                       THURSDAY, OCTOBER 12, 2000

                           U.S. Senate,    
    Subcommittee on Labor, Health and Human
     Services, and Education, and Related Agencies,
                               Committee on Appropriations,
                                                    Washington, DC.
    The subcommittee met at 9:30 a.m., in room SD-124, Dirksen 
Senate Office Building, Hon. Arlen Specter (chairman) 
presiding.
    Present: Senators Specter, Gorton, and Hutchison.

               OPENING STATEMENT OF SENATOR ARLEN SPECTER

    Senator Specter. Ladies and gentlemen, the hearing of the 
Appropriations Subcommittee on Labor, Health, Human Services 
and Education will now proceed.
    The focus of our hearing this morning is to examine the 
findings of the report by the Institute of Medicine, which was 
filed approximately a month ago on September 7, concerning Gulf 
war syndrome.
    There have been extensive hearings on this very perplexing 
problem. Back in September of 1996 there was a joint hearing of 
the Senate Intelligence Committee with the Senate Veterans 
Affairs Committee. At that time, I chaired the Intelligence 
Committee. We have had a series of hearings in the Veterans 
Affairs Committee and had commissioned a special study. Former 
U.S. attorney for the Eastern District of Pennsylvania, Michael 
Rotco, who conducted a long study, published a very voluminous 
report.
    Senator Rockefeller and I felt that there was a connection 
between these ailments of Gulf war syndrome, but the medical 
evidence has been complicated and not decisive. There are more 
than 125,000 veterans from the Gulf war who have complained of 
a variety of ailments. They were exposed to some 33 toxic 
agents. I will not go into them at this time because our 
witnesses will be doing that.
    There has been an important Center for Disease Control 
study, which had found that Gulf war military personnel were 
more likely than those who did not serve in the Gulf war to 
report symptoms suggestive of cognitive dysfunction, 
depression, chronic fatigue, post traumatic stress disorder, 
and respiratory illnesses. That composite would be known 
generally as Gulf war syndrome.
    I have conducted a series of hearings in my own State of 
Pennsylvania and have found many people complaining about very 
serious maladies, having been exposed to these toxic 
substances.
    One of the perplexing problems was the failure of the 
Department of Defense to make candid disclosures as to what 
people faced at Khamisiyah. Finally it came to light, only as a 
result of hearings and investigations, and underscored the need 
for more candor by the Department of Defense. And this whole 
issue illustrates the importance of taking care of our Gulf war 
veterans and trying to define and determine as best we can the 
scientific causes.
    Today's hearing was requested specially by my distinguished 
colleague from Texas, Kay Bailey Hutchison, who has a special 
interest in this subject. And she is a very valued member of 
the subcommittee; as a matter of fact, the full committee; as a 
matter of fact, the full Senate. So we are delighted to see 
Senator Hutchison here.
    And I now yield to you, Kay.

           OPENING STATEMENT OF SENATOR KAY BAILEY HUTCHISON

    Senator Hutchison. Well, thank you very much, Mr. Chairman. 
And I do want to thank you for calling this hearing, because I 
think it is timely that we look into this. And I know all of 
you have testified before congressional committees before. But 
I think that the House committee in the last couple of weeks 
has opened this issue. There was an article just a couple of 
weeks ago about yet another study, saying that there is no link 
between toxins and gulf illnesses.
    But, Mr. Chairman, like you, I was on the Intelligence 
Committee when we started looking at some of these studies. And 
I was on the Armed Services Committee when we got the early 
testimony from the Department of Defense that basically said 
Gulf war syndrome was just psycho-somatic. That was the early 
testimony.
    But then, as we have gone down the road, as I have talked 
to veterans in my home State, where people have just come up to 
me not even knowing of all of the studies that have been done, 
not even knowing that there is something out there for them, 
but they talk about their symptoms.
    And then I have been very interested in the initial studies 
from the University of Texas Southwestern Medical School, which 
I think really starts pinpointing something that we can hold 
onto, that says basically if there is a certain brain receptor, 
you are going to be more susceptible to chemical gases.
    And I think that warrants much further study and perhaps 
could be used for preventive measures for the chemical warfare 
that we might look to be involved in in the future and even for 
people who deal with pesticides in every day life. I think 
there are a lot of potential uses, if we can take a nugget like 
this and see what can be done.
    So I did ask for this hearing to be held for a variety of 
reasons. No. 1, one in seven Desert Storm veterans reporting 
symptoms just cannot be anecdotal. This is too prevalent for us 
not to look further into it, not that you have not looked into 
it. I know you have spent hundreds of millions of dollars.
    But I think now that we are beginning to see that there is 
some scientific basis that perhaps we can expand on, I am 
hoping that we can look at the types of projects that we have 
done and see if there is a way to focus the research and do 
some things that might now give us better results than we have 
gotten so far.
    I guess, Mr. Chairman, that is it. I will not read my 
statement, but I do want to be able to hear from our witnesses. 
And then I do have a number of questions for them that I hope 
will come to the result that I think we all would want. And 
that is to be able to treat the veterans of the Desert Storm 
war for the symptoms that they are experiencing, and then 
second to expand that research for preventive measures. Because 
there is no doubt in my mind that as we look at the security 
threats to the United States, chemical warfare is one of the 
serious threats that I think we could prevent, or at least be 
able to treat.
    I think that will also apply to civilian terrorist attacks. 
We see in Tokyo that a civilian terrorist has figured out how 
the use of sarin gas can be used for threatening purposes. And 
so all the research that we do for our veterans and for the 
prevention of harm to future military personnel will also be 
applicable to civil terrorism.
    And then third, just the general potential for people who 
deal with chemicals in every day life. You have people who work 
in labs. You have people who work in farm jobs. You have people 
who work in chemical plants. It happens that in my home State 
of Texas we have 50 percent of the petro-chemical industry in 
the world. I would love to have this kind of research for our 
civilian population.
    So that is why I am interested. That is why I asked you to 
call the hearing. And I thank you very much for doing it.
    Senator Specter. Thank you very much, Senator Hutchison.
STATEMENT OF BERNARD D. ROSTKER, Ph.D., UNDER SECRETARY 
            FOR PERSONNEL AND READINESS, DEPARTMENT OF 
            DEFENSE
    Senator Specter. Our first witness will be Dr. Bernard 
Rostker, who has been the special Department of Defense expert 
on Gulf war illness. Dr. Rostker served 4 years as Under 
Secretary of the Army and has recently been promoted to Under 
Secretary of Defense for Personnel and Readiness.
    Dr. Rostker, the first question to you, that really is a 
promotion, is it not?
    Dr. Rostker. Yes, it is.
    Senator Specter. OK. We will turn to you first. Our 
practice is to have 5 minute opening statements leaving the 
maximum amount of time for Q&A dialogue. Dr. Rostker.
    Dr. Rostker. Thank you, Mr. Chairman. I would also note 
that just recently the Secretary of Defense made the Office of 
Gulf War Illnesses a permanent office to oversee medical 
readiness and military deployment, as well as to continue our 
focus on Gulf war illnesses. This is, in fact, the ultimate 
lesson to be learned from the Gulf war, and that is that the 
Department was not well suited to deal with non-traditional 
kinds of casualties and issues raised by the Gulf war.
    So we want to make sure we learn the lesson to be 
responsive to our veterans and take their concerns seriously 
and to do what is necessary to account for what happened on the 
battlefield in the Middle East and any future battlefields. So 
you have our commitment.
    The Department is very appreciative of the work of the 
Institute of Medicine and their efforts to review the medical 
literature relating to the possibility of an association 
between the various exposures and the illness of our veterans. 
The IOM reviewed over 10,000 abstracts and over 1,000 peer-
reviewed articles. The IOM used a well-established taxonomy for 
categorizing their findings in terms of whether the literature 
would support a conclusion that sufficient evidence of a casual 
relationship existed, that sufficient evidence of an 
association existed, whether there was limited or suggested 
evidence of an association, whether there was inadequate or 
insufficient evidence to determine whether an association 
existed, or whether there was limited evidence of no 
association.
    As you know, the IOM examined the program of vaccinations 
of sarin, pyridostigmine bromine and depleted uranium. They 
were able to draw a number of conclusions using the five point 
scale. I think the most interesting from our point was their 
conclusions concerning the lack of a robust literature to draw 
conclusions over unusual occurrences with depleted uranium, 
long-term effects of pyridostigmine bromine, exposure to low 
doses of sarin in terms of long-term adverse effects, long-term 
adverse effects from anthrax, botulism vaccine and multiple 
vaccines. These are mainly areas where research has not gone 
forward because these questions had not been previously raised 
in the medical literature.
    We were particularly noteworthy their conclusions 
concerning depleted geranium, that the literature was robust 
enough for the conclusion that there was no association for 
exposure to uranium and lung cancer or exposure to uranium and 
renal dysfunction at exposure levels that one would have 
anticipated were many times greater than that seen in the Gulf.
    All of these conclusions are quite consistent with the 
positions taken by the Office of the Special Assistant, as we 
have gone through the literature ourselves. And so this was 
reinforcing the conclusions that we had. We support the IOM and 
the research community and the need for continuing research. 
And I think some of my colleagues here will talk about that.
    So again, in closing, we appreciate the interest of this 
committee and that others have shown on the health of our men 
and women who serve and who will continue to serve in the armed 
forces. Their health and fitness are our paramount concern. The 
department wants to achieve this goal to take care of these men 
and women and their families and to protect their health.

                           PREPARED STATEMENT

    We recognize that our commitment to keeping our veterans 
healthy does not end when they leave the active service. There 
will remain a strong post-deployment evaluation and program, in 
coordination with the Department of Veterans Affairs, and 
continue to move forward to implement our force health 
protection strategy.
    I appreciate the opportunity to be here. And I will be 
happy to answer any questions you may have.
    [The statement follows:]
                Prepared Statement of Bernard D. Rostker
    Mr. Chairman and members of the Committee, I am pleased to be here 
today to provide testimony before this subcommittee. I am Dr. Bernard 
Rostker, Under Secretary of Defense, Personnel and Readiness and 
Special Assistant to the Secretary of Defense for Gulf War Illnesses, 
Medical Readiness, and Military Deployments. In your invitation letter 
you indicated the purpose of today's hearing was to examine the 
findings of the recent Institute of Medicine's (IOM) Report on the Gulf 
War and Health.
    The IOM committee and staff reviewed more than 10,000 abstracts of 
scientific and medical articles related to the agents selected for 
study and then carefully examined the full text of over 1,000 peer-
reviewed journal articles. The IOM committee used the five established 
categories of association below, because they have gained wide 
acceptance for more than a decade by Congress, government agencies, 
researchers, and veterans groups.
  --Sufficient Evidence of a Causal Relationship.
  --Sufficient Evidence of an Association.
  --Limited/Suggestive Evidence of an Association.
  --Inadequate/Insufficient Evidence to Determine Whether an 
        Association Does or Does Not Exist.
  --Limited/Suggestive Evidence of No Association.
    I have summarized the IOM committee findings in each of these 
categories of association:
Sufficient Evidence of a Causal Relationship
  --Exposure to sarin and a dose-dependent acute cholinergic syndrome 
        that is evident seconds to hours subsequent to sarin exposure 
        and resolves in days to months.
Sufficient Evidence of an Association
  --Pyridostigmine bromide and transient acute cholinergic effects in 
        doses normally used in treatment and for diagnostic purposes.
  --Anthrax vaccination and transient acute local and systemic effects.
  --Botulinum toxoid vaccination and transient acute local and systemic 
        effects.
Limited/Suggestive Evidence of an Association
  --Exposure to sarin at doses sufficient to cause acute cholinergic 
        signs and symptoms and subsequent long-term health effects.
Inadequate/Insufficient Evidence to Determine Whether an Association 
        Does or Does Not Exist
  --Exposure to uranium and lymphatic cancer; bone cancer; nervous 
        system disease; nonmalignant respiratory disease; or other 
        health outcomes (gastrointestinal disease, immune-mediated 
        disease, effects on hematological parameters, reproductive or 
        development dysfunction, genotoxic effects, cardiovascular 
        effects, hepatic disease, dermal effects, ocular effects, or 
        musculoskeletal effects).
  --Pyridostigmine bromide and long-term adverse health effects.
  --Exposure to sarin at low doses insufficient to cause acute 
        cholinergic signs and symptoms and subsequent long-term adverse 
        health effects.
  --Anthrax vaccination and long-term adverse health effects.
  --Botulinum toxoid vaccination and long-term adverse health effects.
  --Multiple vaccinations and long-term adverse health effects.
Limited/Suggestive Evidence of No Association
  --Exposure to uranium and lung cancer at cumulative internal dose 
        levels lower than 200 mSv or 25 cGy.
  --Exposure to uranium and clinically significant renal dysfunction.
    The Department of Defense agrees with the findings of the Institute 
of Medicine. Moreover, their conclusions on Depleted Uranium (DU) 
reinforce the position of the Special Assistant for Gulf War illnesses 
most recently stated in the 3rd annual report ``. . . the scientific 
literature did not indicate negative health effects from the chemical 
toxicity of DU. In addition, the literature review did not reveal 
negative health effects in humans from the exposure to ionizing 
radiation from depleted or natural uranium.'' These conclusions were 
based on work done by RAND and our own investigations modeling the 
levels of exposure to DU our Gulf War veterans potentially experienced.
    The findings by IOM support the direction and emphasis of our 
ongoing research and investigations concerning potential exposures and 
illnesses among our Gulf War veterans.
    The Departments of Defense, Veterans Affairs, and Health and Human 
Services continue to support a robust research program on illnesses 
among Gulf War veterans, sponsoring over 190 distinct research projects 
through fiscal year 2000. As of March 31, 2000, 109 of these projects 
were ongoing. Through fiscal year 1999, the Federal Government had 
cumulative expenditures of over $125 million for research. Of this 
total, the DOD had funded almost $93M or 75 percent of all federal 
research.
    We appreciate the interest this Committee and others have shown in 
the health of the men and women who serve and have served this nation 
in our armed forces. The health and fitness of military personnel have 
long been concerns of those responsible for ensuring troop readiness 
and effectiveness. The Department wants to achieve its goal to take 
care of those men and women and their families, and protect their 
health. We recognize that our commitment to keeping our veterans 
healthy does not end when they leave active service. We will maintain a 
strong post deployment evaluation and care program in coordination with 
the Department of Veterans Affairs and continue to move forward to 
implement our Force Health Protection strategy.
    Again, we appreciate the opportunity to testify before this 
Committee, and look forward to answering your questions.

    Senator Specter. Thank you very much, Dr. Rostker.
STATEMENT OF JOHN R. FEUSSNER, M.D., CHIEF RESEARCH AND 
            DEVELOPMENT OFFICER, DEPARTMENT OF VETERANS 
            AFFAIRS
ACCOMPANIED BY DR. MARK BROWN, DIRECTOR OF ENVIRONMENTAL AGENT 
            SERVICES, DEPARTMENT OF VETERANS AFFAIRS

    Senator Specter. We now turn to Dr. John Feussner, Chief 
Research and Development Officer for the Department of Veterans 
Affairs, a position he has held since 1996. And that involves 
the direction and overseeing of the VA research program.
    Dr. Feussner is accompanied by Dr. Mark Brown, Director of 
Environmental Agent Services for the Department of Veterans 
Affairs.
    So welcome, Dr. Feussner, and the floor is yours.
    Dr. Feussner. Thank you, Mr. Chairman, Senator Hutchison. 
And thank you for the opportunity to discuss the status of the 
current Federal research program on Gulf war veterans' 
illnesses. In your invitation letter, you indicated that the 
purpose of the hearing was to review the findings and 
recommendations of the recent Institute of Medicine report, 
Gulf war and Health, that focused on depleted uranium, the 
nerve gas sarin, pyridostigmine bromide, and vaccines.
    To date, the Federal Government is projecting cumulative 
expenditures of $151 million for Gulf war research from fiscal 
year 1994 through fiscal year 2000. There are over 192 projects 
at various stages of completion in the research portfolio on 
veterans' illnesses. For the sake of brevity, Mr. Chairman, I 
will summarize only the research recommendation of the 
Institute of Medicine report and the response of the Research 
Working Group.
    With regards to sarin, the Institute of Medicine 
recommended that long-term follow-up of populations exposed to 
sarin in the Matsumoto and Tokyo terrorist attacks continue. 
The Research Working Group concurs with that Institute of 
Medicine recommendation.
    The IOM recommended studies on experimental animals to 
investigate the long-term effects of acute short-term exposures 
to sarin at doses that do not cause overt cholinergic effects. 
Since 1996, DOD has funded nine toxicology studies focusing on 
the effects of sarin alone or in combination.
    Mr. Chairman, in addition to the Institute of Medicine 
recommendation on animal studies of sarin, the Research Working 
Group is coordinating three epidemiological studies that are 
focusing on the health of veterans potentially exposed to low-
level sarin during the demolitions at Khamisiyah, one at the 
Naval Health Research Center in San Diego, a second at the 
Oregon Health Sciences University in Portland, and the medical 
follow-up agency of the Institute of Medicine.
    In addition to the IOM recommendation on animal studies on 
sarin, the Research Working Group has also coordinated a 
contract for the medical follow-up agency to perform an 
epidemiological study of the long-term effects of low dose 
exposures to nerve agents in human volunteers in experiments 
conducted at the Aberdeen Proving Grounds in the 1950s.
    With regards to pyridostigmine bromide, the IOM recommends 
research on chemical interactions between pyridostigmine 
bromide, PB, and other agents such as stressful stimuli and 
certain insecticides. Since 1994, VA and DOD have funded 30 
projects related to PB alone or in combination with other 
chemicals or stressful stimuli. One important and consistent 
result of recent studies is that stressful stimuli, such as 
swimming, heat or restraint stress, do not cause an increase in 
the permeability of the blood brain barrier or cause PB to 
cross the blood brain barrier into the brain. The IOM 
recommended research on differences in genetic susceptibility 
that may contribute to increased risk of disease. VA and DOD 
have funded eight projects on genetic factors that may alter 
susceptibility of the effects of sarin and PB.
    With regards to the issue of vaccines, the IOM has 
recommended long-term systematic research to examine potential 
adverse effects of anthrax and botulinum toxoid vaccination in 
multiple species and strains of animals. The Research Working 
Group concurs that long-term research is needed to examine 
potential adverse effects. Such research is under way in DOD 
laboratories. Also, CDC plans to fund non-human primate studies 
on the health effects and efficacy of the anthrax vaccine later 
this fiscal year.
    The IOM recommended that identification of cohorts of Gulf 
war veterans and Gulf war-era veterans for whom vaccine records 
exist, that those veterans be studied. The CDC published a 
study of Air Force Gulf war veterans in 1998, which included 
measuring antibodies to the anthrax and botulinum vaccines to 
determine which individuals had received the vaccine. The CDC 
found that no relationship between the vaccinations and the 
development of a multi-symptom illness.
    Similarly, researchers in the United Kingdom have also 
published a study this year on a cohort of 923 Gulf war 
veterans for whom vaccination records exist. To date, there was 
no association between having received anthrax vaccine and the 
development of a multi-system illness.
    Finally, with regards to depleted uranium, the Institute of 
Medicine recommended continued follow-up of the Baltimore 
cohort of Gulf war veterans with depleted uranium exposure. The 
Research Working Group again concurs. While the Baltimore 
clinicians have seen no definitive evidence of adverse clinical 
outcomes associated with uranium exposure to date, the veterans 
who were involved in these friendly fire incidents will remain 
under continuing medical surveillance.
    The IOM recommended additional studies of the effects of 
depleted uranium in animals. DOD has funded five toxicology 
projects----
    Senator Specter. Dr. Feussner, could you summarize the 
balance of your testimony, please?
    Dr. Feussner. Yes. I am virtually finished.
    Mr. Chairman, we know that combat casualties do not always 
result in obvious wounds and that some veterans from all 
conflicts return with debilitating health problems. The VA 
recognizes its responsibility for developing effective 
treatments and prevention strategies for such illness.

                           PREPARED STATEMENT

    Mr. Chairman, thank you again for permitting me this 
opportunity to summarize our work. I will conclude my testimony 
here and ask that my entire written testimony be entered into 
the record.
    Senator Specter. Your statement in full will be made a part 
of the record, as will all statements.
    [The statement follows:]
                 Prepared Statement of John R. Feussner
    Mr. Chairman and members of the Subcommittee, thank you for this 
opportunity to discuss the status of the current Federal research 
program on Gulf War veterans' illnesses. I serve as the Department of 
Veterans Affairs' (VA) Chief Research and Development Officer and the 
Chairperson of the Research Working Group (RWG) of the Persian Gulf 
Veterans Coordinating Board (PGVCB).
    In your invitation letter, you indicated that the purpose of the 
hearing was to review the findings and the recommendations of the 
recent Institute of Medicine (IOM) report, ``Gulf War and Health, 
Volume 1.: Depleted Uranium, Sarin, Pyridostigmine Bromide, Vaccines.'' 
In addition, I will provide a progress report on research on Gulf War 
veterans' illnesses.
    As you know, the United States deployed nearly 700,000 military 
personnel during the Gulf War from August 1990 to the cease-fire on 
February 28, 1991. Within months of their return, some Gulf War 
veterans reported various symptoms and illnesses that they considered 
to be connected to their war-time service. Veterans, their families, 
and the VA have been concerned about possible health effects from 
exposures during the Gulf War, including chemical warfare agents, the 
anti-nerve agent drug pyridostigmine bromide, vaccines, and depleted 
uranium.

   OVERVIEW OF THE RESEARCH PORTFOLIO ON GULF WAR VETERANS' ILLNESSES
    To date, the Federal government is projecting cumulative 
expenditures of $155 million for Gulf War research from fiscal year 
1994 through fiscal year 2000. There are 192 projects at various stages 
of completion in the research portfolio on these veterans' illnesses. 
In fiscal year 1999 and fiscal year 2000, 42 new projects have been 
added to this portfolio. Research projects have been funded in the 
categories of basic research and applied research, such as clinical 
epidemiology and population-based epidemiologic research. To date, 83 
federally funded projects have been completed. All projects and their 
focus areas are described in detail in annual reports that are 
submitted to Congress each year. An important role of the Research 
Working Group (RWG) is programmatic review and recommendations to 
funding agencies on research proposals that have been competitively and 
scientifically reviewed. The RWG continues to work diligently to foster 
the highest standards of competition and scientific review for all 
research on Gulf War veterans' illnesses. This is consistent with one 
of the recommendations made by the Senate Veterans Affairs' Committee 
in the Report of the Special Investigation Unit on Gulf War Illnesses 
(SIU report). The recommendation was that DOD and VA ``should only fund 
Gulf War health research pursuant to an impartial, scientific peer 
review process, except in the case of the most serious and extreme 
circumstances.''

               IOM REPORT: GULF WAR AND HEALTH, VOLUME 1.
Background on the IOM report
    The Under Secretary for Health sent a letter to the National 
Academy of Sciences Institute of Medicine (IOM) on October 31, 1997 
requesting an IOM study. The purpose of the study was to 
comprehensively review, evaluate, and summarize the published peer 
reviewed scientific literature regarding the associations between 
various Gulf War exposures and adverse health effects experienced by 
some Gulf War veterans. The IOM was also requested to make 
recommendations for additional scientific studies to resolve areas of 
continued scientific uncertainty related to health consequences of Gulf 
War service. On June 24, 1998, VA signed a contract with the IOM for a 
27-month study, at a total cost of $1.25 million.
    This effort was modeled after the successful process VA has used 
since the early 1990s to establish compensation policy for Vietnam 
veterans exposed to Agent Orange.
    Four months later, in October 1998, Congress supported this effort 
with legislative mandates, including the ``Veterans Programs 
Enhancement Act of 1998'' (Public Law No. 105-368) and the ``Persian 
Gulf War Veterans Act of 1998'' (Public Law No. 105-277). The contract 
with IOM meets the requirements of these Acts.
    The IOM reviewed the scientific and medical literature on the 
adverse health effects associated with exposure to sarin, 
pyridostigmine bromide, vaccines, and depleted uranium. The review took 
into account the strength of scientific evidence and the 
appropriateness of the scientific methods used to identify 
associations. It includes an assessment of biologic plausibility that 
these exposures are associated with illnesses experienced by Gulf War 
veterans. In many cases, the data distinguished differences between 
transient and long-term health effects, related to the dose of the 
exposure. Therefore, IOM reported separate findings on the potential 
transient, short-term effects of each exposure, as well as the 
potential long-term effects. As required by Public Law 105-277 and 
Public Law 105-368, the Department is currently evaluating the IOM 
report to determine whether or not a presumption of service connection 
is warranted for any illness related to the exposures covered in the 
report.
    A major strength of the study is that in planning its work, the IOM 
committee asked representatives of veterans service organizations for 
advice in setting its priorities. Veterans advised the committee to 
begin the project by reviewing these specific risk factors. Therefore, 
this report looked at the exposures that were of greatest health 
concern to veterans themselves. The IOM report should provide some 
reassurance to veterans and their families about these health concerns.
Findings and Recommendations of the IOM Report and Response of the 
        Research Working Group
            Sarin
    IOM Findings on potential long-term effects of sarin: IOM concluded 
that there was limited or suggestive evidence of an association between 
``exposure to sarin at doses sufficient to cause acute cholinergic 
signs and symptoms and subsequent long-term health effects.'' IOM 
concluded that there was inadequate evidence to determine whether an 
association does or does not exist between ``sarin at low doses 
insufficient to cause acute cholinergic signs and symptoms and 
subsequent adverse long-term effects.'' This is consistent with one of 
the conclusions of the SIU report, which stated ``There is insufficient 
evidence at this time to prove or disprove that there was an actual low 
level exposure of any troops to chemical weapon nerve agents or that 
any of the health effects some veterans are experiencing were caused by 
such exposure.''
    Basis for IOM Findings on potential long-term health effects of 
sarin: IOM stated that, after human exposures to sarin at doses high 
enough to cause poisoning symptoms, numerous chronic effects have been 
reported. These health effects have been observed in industrial workers 
accidentally exposed to sarin in the U.S. and in the two terrorism 
attacks in Japan. IOM noted that ``there are no well-controlled studies 
of long-term health effects in humans exposed to sarin at doses that do 
not produce acute signs and symptoms.''
IOM Recommendations and Research Working Group Response:
    1. Long-term follow-up of populations exposed to sarin in the 
Matsumoto and Tokyo terrorist attacks.
    The RWG concurs with IOM's recommendation that Japanese scientists 
should continue the long-term follow-up of populations exposed to sarin 
in the Matsumoto and Tokyo terrorist attacks. We plan to keep apprised 
of the results of these studies.
    2. Studies in experimental animals to investigate the long-term 
effects of an acute, short-term exposure to sarin at doses that do not 
cause overt cholinergic effects and minimal acetylcholinesterase 
inhibition.
    Since 1996, DOD has funded several studies of the long-term effects 
of short-term sarin exposure at doses that do not cause overt symptoms 
and cause only minimal acetylcholinesterase inhibition. Nine toxicology 
studies are focusing on the effects of sarin, alone or in combination. 
These combinations have included PB, DEET, permethrin, chlorpyrifos, 
heat stress and/or exercise stress.
    3. In addition to the IOM recommendation on animal studies on 
sarin, the RWG is coordinating three epidemiological studies that are 
focusing on the health of veterans potentially exposed to low-level 
sarin due to the demolitions at Khamisiyah. The results of one of these 
projects were published in 1999 (project DOD-1B). The conclusion was 
there were no differences in rates of health problems among Gulf War 
veterans, who were potentially exposed to subclinical levels of sarin, 
compared to Gulf War veterans who were not exposed. The second 
Khamisiyah-related project is being performed by the Oregon Health 
Sciences University (DOD-63). The purpose is to compare neurological 
symptoms and results of neurobehavioral tests between Gulf War 
veterans, who were potentially exposed to low levels of sarin, versus 
Gulf War veterans who were not exposed. The third Khamisiyah-related 
project is being performed by the Medical Follow-Up Agency (MFUA) of 
the IOM (DOD-69). The purpose is to compare self-reported health 
problems between Gulf War veterans, who were potentially exposed to low 
levels of sarin, versus Gulf War veterans who were not exposed.
    4. In addition to the IOM recommendation on animal studies on 
sarin, the RWG is coordinating a contract for MFUA to perform an 
epidemiologic study of the long-term effects of short-term exposure to 
nerve agents in human volunteers in experiments conducted at Aberdeen 
Proving Ground in the 1950s to 1970s (DOD-93).
    5. Research on genetic factors that may alter susceptibility to 
sarin toxicity.
    VA and DOD have funded a number of research projects on genetic 
factors that may alter the susceptibility to sarin and/or PB toxicity. 
These studies are described in detail in the section on PB below.
            Pyridostigmine Bromide (PB)
    IOM Findings on potential long-term effects of PB: IOM concluded 
that there was inadequate evidence to determine whether an association 
does or does not exist between PB and long-term adverse health effects.
    Basis for IOM Findings on potential long-term health effects of PB: 
IOM noted that no reports of chronic toxicity were available related to 
human PB exposure in clinical or military populations. IOM reviewed two 
studies of PB use in Gulf War veterans, and concluded ``the 
epidemiological data do not provide evidence of a link between PB and 
chronic illness in Gulf War veterans.''
IOM Recommendations and Research Working Group Response:
    1. Research on chemical interactions between PB and other agents 
such as stressful stimuli, and certain insecticides.
    Since 1994, VA and DOD have funded 30 projects related to PB, alone 
or in combination with other chemicals or stressful stimuli. In 
particular, VA and DOD have funded 18 projects on the potential 
interactions between PB and other agents. Five of these projects have 
published results, focusing on the effects of PB in rodents, in 
combination with DEET, permethrin, swimming stress, restraint stress, 
or exercise stress (projects VA-49, DOD-10, DOD-37, DOD-62, DOD-65). 
One important and consistent result of recent studies is that stressful 
stimuli, such as swimming stress or restraint stress, do not cause an 
increase in the permeability of the blood-brain barrier, or cause PB to 
cross the blood-brain barrier into the brain. In 1996, the earliest 
research in this area was performed, which indicated increased 
permeability of the blood brain barrier to PB, due to swimming stress 
in a particular strain of mice. Several more recent studies have failed 
to replicate this finding using a variety of species, a variety of 
types of stressful stimuli, and extremely high doses of PB.
    2. Research on differences in genetic susceptibility (e.g., genetic 
polymorphisms of butyrylcholinesterase or paraoxonase) that may 
contribute to increased risk of disease.
    VA and DOD have funded eight projects on genetic factors that may 
alter susceptibility to the effects of PB or sarin, including 
polymorphisms of enzymes. Four projects in humans are evaluating the 
effects of genetic differences in polymorphisms of 
acetylcholinesterase, butyrylcholinesterase, and/or paraoxonase 
(projects DOD-21, DOD-60, DOD-65, DOD-112). Two projects in humans are 
evaluating the effects of gender and weight (project DOD-11, DOD-64). 
Two projects in rats are evaluating the effects of genetic differences 
in polymorphisms of acetylcholinesterase and butyrylcholinesterase (VA-
5D, VA-49).
    3. Epidemiological studies on the possible long-term health effects 
of PB.
    The RWG concurs with IOM that neurologists, who perform long-term 
follow-up of the course and treatment of myasthenia patients, should 
consider the possible long-term effects of PB. These patients take PB 
for many years. IOM concluded that PB has been used safely and 
effectively in thousands of myasthenia gravis patients since the 1950s. 
However, there has not been a systematic evaluation to determine if 
there are subtle long-term effects. We plan to keep apprised of the 
results of such long-term studies of myasthenia gravis patients, and we 
have instituted contacts on this issue with the Myasthenia Gravis 
Foundation of America.
            Vaccines
    IOM Findings on the potential long-term effects of vaccines: IOM 
concluded that there was inadequate evidence to determine whether an 
association does or does not exist between anthrax vaccination, 
botulinum toxoid vaccination, or multiple vaccinations, and long-term 
adverse health effects.
    Basis for IOM Findings on potential long-term health effects of 
vaccines: IOM stated there were no published, controlled studies of the 
long-term effects of anthrax vaccination or botulinum toxoid 
vaccination. IOM reviewed only a few studies of the long-term effects 
of multiple vaccinations, which were too limited to draw conclusions.
IOM Recommendations and Research Working Group Response:
    1. Long-term systematic research to examine potential adverse 
effects of anthrax and botulinum toxoid vaccination in multiple species 
and strains of animals.
    The RWG concurs that long-term research is needed to examine 
potential adverse effects of anthrax and botulinum toxoid vaccination 
in experimental animals. Such research is underway in DOD laboratories. 
Also, CDC plans to fund non-human primate studies of the health effects 
and efficacy of the anthrax vaccine in late 2000.
    2. Identification of cohorts of Gulf War veterans and Gulf War era 
veterans, for whom vaccination records exist, followed by careful 
studies of current symptoms, functional status, and disease status.
    The Centers for Disease Control and Prevention (CDC) published a 
study of Air Force Gulf War veterans in 1998, which included measuring 
antibodies to anthrax and botulinum to determine which individuals had 
received the vaccines. The CDC found no relationship between the 
vaccinations and the development of a multisymptom illness (chronic 
symptoms of fatigue, cognitive and mood problems, and musculoskeletal 
pain).
    The United Kingdom has also published a study in 2000 on a cohort 
of 923 Gulf War veterans for whom vaccination records exist. There was 
no association between having received the anthrax vaccine and the 
development of multisymptom illness, as defined by CDC.
    3. Long-term longitudinal studies of the participants in the 
Anthrax Vaccine Immunization Program that would actively monitor and 
systematically collect and analyze data about symptoms, functional 
status, and disease status.
    In 1999, DOD funded a long-term longitudinal study of participants 
in the Anthrax Vaccine Immunization Program. The Naval Health Research 
Center is establishing DOD-wide surveillance of hospitalizations in 
military hospitals, linking these to data on anthrax vaccine recipients 
(project DOD-99). This active surveillance system ensures early 
detection of any associations between vaccinations and severe reactions 
that require hospitalizations. In addition, there are several ongoing 
projects that are following smaller groups of vaccine recipients to 
evaluate adverse effects. In Chapter 7, IOM summarizes several of these 
smaller completed and ongoing human studies, nearly all of which are 
unpublished. IOM strongly urges the DOD investigators who are 
conducting these studies to submit their results to peer-reviewed 
journals for publication. Additionally, IOM recently started a new two-
year study on the safety and efficacy of the anthrax vaccine, funded by 
DOD. This new study will review some of the unpublished, non-peer 
reviewed information that was not previously available.
            Depleted Uranium (DU)
    IOM Findings on the potential long-term health effects of DU: IOM 
concluded that there is limited or suggestive evidence that there is no 
association between exposure to uranium and ``lung cancer at cumulative 
internal dose levels lower than 200 millisieverts or 25 centigrays.'' 
IOM also concluded that there is limited or suggestive evidence that 
there is no association between exposure to uranium and ``clinically 
significant renal dysfunction.'' IOM concluded that there was 
inadequate evidence to determine whether an association does or does 
not exist for several other potential long-term health effects.
    Basis for IOM Findings on the potential long-term health effects of 
DU: IOM states that lung cancer has been the focus of many cohort 
studies of workers in the uranium processing industry. Many of these 
studies were large (thousands of subjects) and had a long period of 
follow-up (more than 20 years). Lung cancer mortality was not increased 
among workers in most of these cohorts, and IOM focused on the best 
quality studies in forming its conclusions about radiation exposure and 
lung cancer. IOM states that the weight of the human evidence indicates 
little or no clinically important kidney toxicity due to uranium 
exposure. IOM cited the strongest evidence as the absence of kidney 
damage in Gulf War veterans exposed to DU from embedded shrapnel. 
Kidney function was normal in these veterans, years after exposure, 
despite very high urinary uranium concentrations.
IOM Recommendations and Research Working Group Response:
    1. Continued follow-up of the Baltimore cohort of Gulf War veterans 
with DU exposure. Long-term studies of the health of other Gulf War 
veterans at high risk for DU exposure (e.g. cleanup or radiation 
control units).
    The RWG concurs with the long-term follow-up of the veterans in the 
Baltimore cohort, who were injured during friendly fire incidents. This 
cohort was expanded in 1999, beyond the original 33 individuals. While 
the Baltimore researchers have seen no definitive evidence of adverse 
clinical outcomes associated with uranium exposure to date, the 
veterans who were involved in the friendly fire incidents will remain 
under continuing medical surveillance. This is consistent with the SIU 
report, which stated that DOD and VA should ``utilize the existing VA 
Depleted Uranium Medical Follow-Up Program to provide timely and in-
depth medical evaluations to active duty troops and veterans with DU 
injuries.''
    In addition, since mid-1998, VA and DOD have offered a DU medical 
evaluation to hundreds of other veterans with potential DU exposure, 
such as those involved in cleanup operations or radiation control 
units. To date, the published data have shown that only veterans who 
have retained metallic fragments have demonstrated persistently 
elevated urinary uranium levels.
    2. Continued follow-up of the cohorts of uranium processing 
workers.
    The RWG concurs that the long-term follow-up should continue of 
cohorts of uranium processing workers. Many of these studies involve 
employees of manufacturing facilities managed by the Department of 
Energy or its contractors. Because of the recent increase in interest 
in the employees of these facilities, ongoing surveillance is likely to 
intensify in the future. We plan to keep apprised of the results of 
these studies.
    3. Additional studies of the effects of depleted uranium in 
animals.
    DOD has funded five toxicology projects that are investigating the 
health effects of DU in experimental animals (DOD-7A, DOD-7B, DOD-121, 
DOD-122, DOD-123). In particular, since 1994, the Armed Forces 
Radiobiology Research Institute (AFRRI) has been investigating the 
health effects of embedded DU pellets on rats. In Chapter 4, IOM cites 
the results of several published AFRRI studies. For example, there was 
no detectable kidney toxicity in rats embedded with DU pellets, even at 
very high concentrations of urinary uranium. Also, in early 2000, DOD 
released a Broad Agency Announcement to fund additional studies of 
health effects of heavy metals in experimental animals, including DU. 
Outcomes of particular interest include effects on the lung, liver, 
kidney, and nervous systems; and localized soft tissue responses of 
embedded fragments. Awards for these projects should occur by late 
2000.
Plans for Additional Reviews by the IOM
    The present study is only the first phase of a long-term IOM 
review. VA has already initiated a new contract for the next phase of 
IOM's review of Gulf War environmental risk factors. The contract calls 
for the same type of thorough review of peer reviewed literature on the 
potential health effects from exposure to solvents and pesticides used 
during the Gulf War. As with the previous study, it will require two 
years to complete, starting September 1, 2000, at a total cost of $3.57 
million. Following that, we anticipate looking at the several other 
Gulf War risk factors. In addition, the VA and the IOM are committed to 
issuing updated reports as new evidence appears. VA has not ruled out 
any exposures as a possible contributor to Gulf War veterans' 
illnesses.
    In summary, a process is in place to review the scientific evidence 
that becomes available regarding any health consequences from service 
during the Gulf War and to grant compensation benefits using the same 
model as was used for Vietnam veterans regarding Agent Orange.
       status report on research on gulf war veterans' illnesses
    We know that combat casualties do not always result in obvious 
wounds, and that some veterans from all conflicts return with 
debilitating health problems. VA recognizes its responsibility for 
developing effective treatments and prevention strategies for such 
diseases. Studies clearly show that some Gulf War veterans report a 
variety of chronic and ill-defined symptoms including fatigue, 
neurocognitive, and musculoskeletal problems, at rates that are 
significantly greater than non-deployed veterans.
Four Major Research Initiatives on Illnesses in Gulf War Veterans
    Highlights of the ongoing research efforts on Gulf War veterans' 
illnesses include two major treatment trials, Phase III of the VA 
National Survey, and a new epidemiological study of amyotrophic lateral 
sclerosis (ALS) in Gulf War veterans.
    As a result of epidemiological findings to date, subgroups of ill 
Gulf War veterans have been identified for whom trials of potential 
treatment are appropriate. In the spring of 1998, the VA Cooperative 
Studies Program initiated planning for two treatment trials, 
subsequently known as the ``ABT'' (antibiotic treatment) and ``EBT'' 
(exercise-behavioral therapy) trials. Both trials underwent thorough 
scientific review and were approved for funding only after rigorous 
external review provided by the Cooperative Studies Evaluation 
Committee. Patient characteristics for entry into both trials are 
similar. All veterans who served in the Gulf between August 1990 and 
August 1991 are eligible for the studies. Patients are considered to 
have Gulf War Veterans' Illnesses (GWVI) if they have at least two of 
three symptoms (fatigue, musculoskeletal pain, neurocognitive 
dysfunction) that began after August 1990 and that have lasted for more 
than six months up to the present.
    The ABT trial has completed its enrollment of 491 Gulf War veterans 
at 28 sites throughout the U.S. The study initiated patient accession 
in May of 1999. The primary hypothesis of the study is that antibiotic 
treatment directed against mycoplasma species will improve functional 
status of patients with GWVI who are tested as mycoplasma positive at 
baseline. The total cost of this treatment trial is approximately $13 
million. The trial will be completed in October 2001, when patient 
follow-up is finished.
    Preliminary demographic information indicates that 15 percent of 
the study participants are women, nearly 20 percent represent minority 
groups, 37 percent have attained an educational level of college or 
higher, and about 70 percent are employed. Nearly 85 percent of 
patients enrolled in the study exhibit all three symptoms of fatigue, 
pain, and neurocognitive difficulties.
    The EBT trial has completed enrollment of nearly 1,100 Gulf War 
veterans at 20 sites throughout the U.S. The study initiated patient 
accessions in April of 1999. The primary hypotheses of the study is 
that both aerobic exercise and cognitive behavioral therapy (CBT) will 
significantly improve physical function in veterans with GWVI, and that 
the combination of CBT and exercise will be more beneficial than either 
treatment would be alone. The cost of this treatment trial is 
approximately $9.3 million. The trial will be completed on or about 
December 2001.
    Mr. Chairman, I will now provide you with an update of the VA 
National Survey of Persian Gulf Veterans authorized by Public Law 103-
446. The National Survey is designed to determine the prevalence of 
symptoms and illnesses among a national random sampling of Gulf War 
veterans. The Survey is being conducted in three phases. Phase I was a 
population-based mail survey of the health of 30,000 randomly selected 
veterans from the Gulf War era (15,000 Gulf War veterans and 15,000 
non-Gulf War veterans, males and females). The data collection phase is 
complete, analysis of the data continues, and the first report has been 
published in the scientific literature. Phase II consisted of a 
telephone interview of 2,000 non-respondents from Phase I (1,000 from 
each group) to determine if there are any response differences between 
respondents and non-respondents. Phase II is complete. In Phase III, 
2,000 of the veterans who responded to the postal survey are being 
invited, along with their family members, to participate in a 
comprehensive physical examination protocol. These examinations are 
being conducted at 15 VA medical centers and involve specialized 
examinations including neurological, rheumatological, psychological, 
and pulmonological evaluations. When the National Survey is complete we 
will have a much clearer picture of the prevalence of symptoms and 
illnesses among Gulf War veterans.
    The VA's Office of Research and Development awarded funds for Phase 
III of the National Health Survey of Persian Gulf Veterans in November 
1998. Thus far, this study has examined approximately 1,600 veterans, 
plus 2,000 of their spouses and children. The study will cost 
approximately $12 million and will complete patient recruitment in May 
of 2001.
    The medical evaluations in Phase III are designed to determine:
  --Whether Gulf War veterans have an increased prevalence of the 
        following conditions frequently reported in the literature, 
        compared to a control group of non-deployed veterans: Chronic 
        Fatigue Syndrome (CFS); Fibromyalgia (FM); neurologic 
        abnormalities, including peripheral neuropathy and cognitive 
        dysfunction; and post-traumatic stress disorder (PTSD).
  --Whether the specific medical conditions of arthritis, dermatitis, 
        hypertension, bronchitis, and asthma, which have been reported 
        more frequently among Gulf War veterans compared to non-
        deployed veterans, are at higher prevalence among deployed Gulf 
        War veterans upon objective clinical examination.
  --Whether the prevalence of any of these conditions is greater among 
        the spouses of Gulf War veterans than among spouses of non-
        deployed veterans.
  --Whether the prevalence of medical conditions and major birth 
        defects found on a pediatric physical examination in the 
        children conceived after the war is greater for Gulf War 
        veterans than for non-deployed veterans.
    Recently, Gulf War veterans have voiced concerns about a possible 
association between amyotrophic lateral sclerosis (ALS) and service in 
the war. Although there is no clear indication of an excess rate of ALS 
among Gulf veterans, the available data could represent an 
underestimate of the actual rate. Furthermore, preliminary data 
suggested that the age distribution of cases of ALS in Gulf veterans 
appeared to be younger than the age distribution of cases of ALS in the 
general U.S. population. Accordingly, VA is leading a research effort 
to identify all cases of ALS, or other motor-neuron diseases, occurring 
among Gulf War veterans. VA is collaborating with DOD, CDC, and various 
university disease experts to determine the veterans' health status and 
to describe their exposures to potential causal and risk factors for 
ALS, based on clinical examinations at VA or non-VA centers of 
excellence in neurologic diseases. This initial case-finding effort is 
ongoing, and is planned to continue through February 2001. This study 
should provide the most definitive information about the rate of ALS 
among Gulf veterans, and the age distribution of the diagnosed 
patients.
Other Research Initiatives on Illnesses in Gulf War Veterans
    The research program has yielded several important results. Some of 
the highlights of recent research findings include:
  --Population-based epidemiological studies have shown that Gulf War 
        veterans report more symptoms than non-deployed veterans of the 
        same era.
  --The population-based study of Gulf War veterans in Iowa has shown 
        that nearly 90 percent of Gulf War veterans reported their 
        health status as ``good'' to ``excellent,'' while the remainder 
        rated their health status as ``fair'' to ``poor,'' using 
        standard measures of health status. A minority of them (14 
        percent) experienced a significant decline in their health 
        status. Declines were noted in physical functioning and social 
        functioning, while mental health scales showed improvement.
  --Several major studies suggest that Gulf War veterans do not suffer 
        from a unique, previously-unrecognized syndrome. In particular, 
        four studies have evaluated the health of thousands of Gulf War 
        veterans who served in: (a) the U.S. Air Force; (b) the U.S. 
        Navy; (c) all three U.S. services; and (d) all three services 
        from Great Britain. In each study, Gulf War veterans and 
        comparison groups of non-deployed veterans reported the same 
        patterns of symptoms. The results of these four studies are 
        consistent with IOM's conclusion that ``Thus far, there is 
        insufficient evidence to classify veterans' symptoms as a new 
        syndrome.'' IOM also concluded ``All Gulf War veterans do not 
        experience the same array of symptoms . . . Thus, the nature of 
        the symptoms suffered by many Gulf War veterans does not point 
        to an obvious diagnosis, etiology, or standard treatment.'' 
        This is also consistent with the SIU report, which stated that 
        ``What SIU investigation found almost from the beginning was 
        that the concept of a `syndrome' does not accurately describe 
        what is collectively referred to as `Gulf War illnesses.' 
        Instead, these veterans experience a variety of symptoms, 
        illnesses, and disorders that do not appear to fit a particular 
        pattern.''
  --The RWG has determined that population based longitudinal studies 
        to determine the long-term health of Gulf War veterans are a 
        high priority. There are two population based longitudinal 
        studies underway that are supported by DOD and the Centers for 
        Disease Prevention and Control (CDC). They are Iowa (CDC and 
        DOD), and the United Kingdom (U.S. DOD). Altogether, these two 
        studies are following up a total of approximately 12,000 
        veterans. Each of these studies has used questionnaires, 
        including physical symptoms, psychological symptoms, and 
        exposures during the Gulf War. Both the Iowa and United Kingdom 
        studies have included comprehensive medical histories and 
        physical examinations. VA will request proposals to conduct a 
        pilot of a longitudinal study based on its National Gulf War 
        Survey.
  --Neurobehavioral studies of Gulf War veterans and control 
        populations suggest that some Gulf War veterans may have brain 
        function abnormalities in such areas as memory, cognition, and 
        motor control. The current RWG research portfolio includes 
        seven studies using methods of sophisticated brain imaging such 
        as conventional and functional magnetic resonance imaging 
        (fMRI), and magnetic resonance spectroscopy.
  --VA has developed a plan to establish two new Centers for the Study 
        of War-Related Illnesses. These new Centers will assist VA in 
        the development of appropriate preventive strategies to 
        minimize illness and injury following future conflicts, 
        including both combat and peace-keeping operations, and to 
        develop new approaches for improving the care of active-duty 
        and veteran patients with war-related illnesses. VA has 
        released its Request for Proposal for these new Centers and 
        plans to fund them within the next few months.
  --In early 2000, DOD published Broad Agency Announcements to announce 
        the availability of research funding on four topics. The 
        selection and awarding of funds will be completed by the end of 
        2000. The topics are:
      1. Toxicity of heavy metals that are relevant to the military, 
        including DU;
      2. Biomarkers to assess toxic chemical exposures and health 
        effects;
      3. Consequences of deployment stress on health and performance; 
        and
      4. Physiologically based methods to assess health consequences of 
        deployment.

                              CONCLUSIONS
    As the Federal research program continues to provide more results, 
we will substantially increase our understanding of Gulf War veterans' 
illnesses, which, in turn, will enhance our ability to diagnose and 
treat them. In addition, this newly gained knowledge will enhance 
prevention and intervention in illnesses in participants of future 
deployments.
    Mr. Chairman, thank you again for permitting me this opportunity to 
summarize our work to date so that, using science, we may better 
understand the health problems of Gulf War veterans. You have my 
assurance that we will continue this effort to resolve or ameliorate 
health problems in this population to the greatest extent possible. Mr. 
Chairman, I will conclude my testimony here and am happy to answer any 
questions you or other Committee members may have.

    Senator Specter. We have been joined by our distinguished 
colleague from Washington.
    Senator Gorton, would you care to make any comments at this 
time?
    Senator Gorton. No, thank you.
STATEMENT OF DRUE H. BARRETT, Ph.D., CHIEF, HEALTH 
            ACTIVITY WORKING GROUP, CENTERS FOR DISEASE 
            CONTROL AND PREVENTION, DEPARTMENT OF 
            HEALTH AND HUMAN SERVICES
    Senator Specter. Then we will move now to our third 
witness, Dr. Drue Barrett, who serves as the Center for Disease 
Control's liaison to the Department of Health and Human 
Services. Dr. Barrett is the chief of the Veterans Health 
Activity Working Group in the Division of Environmental Hazards 
and Health Effects at the National Center for Environmental 
Health.
    That is quite a litany, Dr. Barrett. The floor is yours.
    Dr. Barrett. Thank you. Mr. Chairman, Senator Hutchison, 
Senator Gorton, thank you for the opportunity to be here and to 
discuss the recent Institute of Medicine report, and also to 
update the committee on the Centers for Disease Control and 
Prevention's research activities dealing with Gulf war 
veterans' illnesses.
    I will focus my testimony on the discussion of the IOM 
report. But first I would like to provide some background 
information on the types of studies that have been initiated to 
investigate Gulf war veterans' health concerns. Efforts to 
investigate Gulf war veterans's health concerns have included 
population-based studies, including cross-sectional and 
longitudinal cohort studies, cluster and cross-sectional 
studies of specific military units, commands, or branches of 
service, and studies of United States and other coalition 
forces.
    Control subjects have been assessed in order to compare 
prevalence rates across groups. Assessment approaches have 
included mail and telephone surveys, in-person questionnaires, 
and physical examinations. The number of respondents 
participating in these various studies have ranged from a few 
hundred to over 20,000. Response rates have ranged from very 
poor, at 31 percent, to very good, at 76 percent.
    The findings have been very consistent, regardless of the 
types of studies that have been used. We find that active duty 
and reserve personnel deployed to the Gulf war nearly all 
report self-assessed symptoms at a higher rate than comparison 
groups. Gulf war veterans are also more likely to rate their 
overall health status since the Gulf war as poorer than their 
nondeployed peers. However, few studies have been able to 
document abnormalities on physical examination and routine 
laboratory tests.
    A number of different environmental exposures have been 
mentioned with regard to the Gulf war. There have been several 
studies that have explored the relationship between these 
exposures and subsequent health outcomes. However, as noted by 
the Institute of Medicine, this research has been hampered by a 
lack of objective exposure data. And so most of the studies 
have had to rely on self-reported health outcomes and self-
reported exposures, which creates difficulty in studying these 
issues.
    To date, no specific exposure has been identified that 
would be responsible for the various types of problems that are 
being reported by Gulf war veterans. In an effort to further 
examine the relationship between health effects and exposures, 
the Institute of Medicine reviewed the scientific and medical 
literature on depleted uranium, sarin, pyridostigmine bromide, 
and vaccines.
    Because of the lack of exposure data among Gulf war 
veterans, the committee was not able to assess the likelihood 
that Gulf war veterans' health problems are associated with or 
caused by these agents. Instead, most of the conclusions in the 
report are based on occupational and clinical exposures.
    As the chairman of the IOM committee is here to discuss the 
report, I will not focus on any of the findings of the report. 
What I would like to do is just comment on some of the methods 
used by the IOM.
    The IOM targeted the exposures of greatest concern to Gulf 
war veterans, as determined by meetings with veterans. They 
based their conclusions on an extensive review of 
scientifically reviewed articles. They used rigorous, well-
established methods for evaluating the strength of the evidence 
for determining the association between studied exposures and 
health outcomes. This included examining the strength of the 
association, the dose response relationship, the consistency of 
the association, the temporal relationship between exposure and 
outcome, the specificity of the association, and biological 
plausibility.
    They also considered alternative explanations, such as 
chance and various forms of bias. The IOM critically examined 
each study and considered specific study design elements, such 
as the method of exposure assessment, sample size, length of 
follow-up, and control of confounding variables. Similar review 
methods have been used previously by IOM committees in studying 
other health issues.
    Although the IOM findings cannot provide conclusive answers 
about the health impact of these exposures on Gulf war 
veterans, this report may provide some reassurance that among 
other populations there does not seem to be strong evidence 
that these exposures are associated with long-term health 
effects, especially in the absence of acute effects.

                           PREPARED STATEMENT

    Mr. Chairman, I refer you to my written testimony for a 
review of CDC's Gulf war research activities and how we have 
coordinated our efforts with the other responsible departments. 
And I will be happy to answer any questions.
    Senator Specter. Thank you very much, Dr. Barrett.
    [The statement follows:]
                 Prepared Statement of Drue H. Barrett
    Mr.Chairman, thank you for the opportunity to update the 
Subcommittee on the Centers for Disease Control and Prevention's (CDC) 
research programs pertaining to Gulf War veterans' illnesses. I am Dr. 
Drue Barrett, Chief of the Veterans' Health Activity Working Group in 
the Division of Environmental Hazards and Health Effects of the 
National Center for Environmental Health (NCEH). I serve as CDC's 
liaison to the Department of Health and Human Services (HHS) on Gulf 
War issues. I am a member of the Research Working Group that serves the 
Persian Gulf Veterans Coordinating Board and the Military and Veterans 
Health Coordinating Board. NCEH has been designated as the lead Center 
at CDC for addressing Gulf War veterans' health concerns; however other 
Centers within CDC have also been involved in this effort, most 
notably, the National Center for Infectious Diseases.
    My testimony will include: (1) a discussion of the recent Institute 
of Medicine (IOM) report on depleted uranium, sarin, pyridostigmine 
bromide, and vaccines; (2) a review of CDC's Gulf War research 
activities; and (3) an assessment of the Federal research effort to 
address the health concerns of Gulf War veterans.

                               BACKGROUND
    Shortly after the end of the Gulf War, reports began to emerge that 
veterans were experiencing a variety of somatic symptoms generally not 
accompanied by physical signs or laboratory abnormalities. The most 
commonly reported symptoms include complaints of chronic fatigue, 
headache, muscle and joint aches and pains, and cognitive disturbances.
    In 1994, the findings of a National Institutes of Health Technology 
Assessment Workshop established the priority of conducting controlled 
epidemiologic research to determine the prevalence of symptoms among 
Gulf War veterans and a number of such studies have been completed. 
This research effort has included population-based studies, including 
cross-sectional and longitudinal cohort studies; cluster and cross-
sectional studies of specific military units, commands, or branches of 
service; and studies of U.S. and other coalition forces. Importantly, 
control subjects have been assessed in order to compare prevalence 
rates across groups. These control groups have included military 
personnel activated during the time of the Gulf War who remained 
stateside, troops deployed to other regions during the Gulf War, and 
military participants in other conflicts. Assessment approaches have 
included mail and telephone surveys, in person questionnaires and 
interviews, and physical examinations. The number of respondents 
participating in these studies have ranged from a few hundred to over 
20,000. Response rates have ranged from poor (31 percent) to very good 
(76 percent).
    The findings of these studies have been remarkably consistent, 
regardless of the study methodology employed. Active duty and reserve 
personnel deployed to the Gulf War report nearly all assessed symptoms 
at a higher rate than comparison groups. Gulf War veterans are also 
more likely to rate their overall health status since the Gulf War as 
poorer than their non-deployed peers. The most useful or generalizable 
studies of symptom prevalence have been population-based, have used a 
comparable control group of military era personnel not deployed to the 
Gulf, and have used at least some standardized or validated instruments 
to allow comparisons to other populations or studies.
    A number of environmental exposures have been mentioned in relation 
to Gulf War veterans' health concerns. These have included 
environmental and occupational pollutants (e.g., sand, petroleum 
products, pesticides, Chemical Agent Resistant Coating paint, smoke 
from oil-well fires), medical prophylaxes (e.g., anthrax and botulinum 
toxin vaccines and pyridostigmine bromide), depleted uranium munitions, 
and biologic and chemical warfare agents. Several studies have explored 
the relationship between exposures during the Gulf War and subsequent 
health outcomes. However, as noted by the IOM in their recent report, 
this research has been hampered by a lack of objective exposure data. 
Since most studies have examined the association between retrospective 
recall of exposures and self-reported health outcomes, it has been 
difficult to eliminate the impact of potential recall bias. To date, no 
specific exposure has been identified as responsible for the various 
health complaints of Gulf War veterans.

              IOM REPORT ON GULF WAR EXPOSURES AND HEALTH
    In an effort to further examine the health effects associated with 
exposures encountered during the Gulf War, the IOM reviewed the 
scientific and medical literature on depleted uranium, sarin, 
pyridostigmine bromide, and vaccination against botulinum toxin and 
anthrax. Because of the lack of data on actual exposures among Gulf War 
veterans, the committee was not able to assess the likelihood that Gulf 
War veterans' health problems are associated with or caused by these 
agents. Instead most of the conclusions in the report are based on 
occupational and clinical exposures. Overall the committee found that 
there was not enough evidence to link long-term health problems with 
exposure to agents known to be present during the Gulf War. At most the 
committee found limited evidence from three studies that might suggest 
an association between sarin and long-term health effects. Alternative 
explanations for any possible association could not be ruled out. The 
committee found sufficient evidence for short-term health effects 
associated with high doses of pyridostigmine bromide and anthrax 
botulinum toxoid vaccinations. Pyridostigmine bromide was found to be 
associated with transient, tolerable, and mild gastrointestinal and 
muscular symptoms, and the anthrax and botulinum toxoid vaccinations 
were found to be associated with redness, swelling, and tenderness at 
the site of injections among other mild and short-term symptoms.
    The IOM based their conclusions on an exhaustive review of 1,000 
peer reviewed journal articles. They used rigorous, well-established 
methods for evaluating the strength of the evidence for determining the 
association between the studied exposures and health outcomes. This 
included examining the strength of the association, the dose-response 
relationship, the consistency of the association, the temporal 
relationship between exposure and outcome, the specificity of the 
association, and biological plausibility. They also considered other 
alternative explanations such as chance and various forms of bias. The 
IOM critically examined each study and considered specific study design 
elements, such as method of exposure assessment, sample size, length of 
follow-up, and control of confounding variables. Similar review methods 
have been used previously by IOM committees studying other health 
issues, such as vaccine safety, herbicides used in Vietnam, and indoor 
pollutants related to asthma. Although the IOM findings cannot provide 
conclusive answers about the health impact of depleted uranium, sarin, 
pyridostigmine bromide, and vaccines on Gulf War veterans, this report 
may provide some reassurance that among other populations there does 
not seem to be strong evidence that in the absence of acute effects 
these exposures are associated with long term health effects.

                      CDC-FUNDED GULF WAR STUDIES:
    In order to further explore what is known about Gulf War veterans' 
health concerns, I would like to review CDC's research activities in 
this area. CDC's initial efforts were to examine the health impact of 
the oil well fires. Researchers from the NCEH and several other Federal 
agencies conducted cross-sectional surveys of workers in Kuwait City in 
May 1991 and of firefighters in the oil fields in October 1991. Blood 
samples were tested for 31 volatile organic compounds (VOCs) and 
compared to a referent group of persons living in the United States 
collected as part of the third National Health and Nutrition 
Examination Survey (NHANES III). The median concentration of VOCs among 
the firefighters was quite elevated. However, among the non-
firefighting personnel, VOC concentrations were equal to or lower than 
the levels found among the reference group.
    NCEH also collaborated with the Department of Defense (DOD) in a 
study of 30 members of an Army Unit located in Germany. Blood from 
these military personnel was tested for VOCs at three points in time, 
prior, during and after their deployment to Kuwait. Only one compound, 
tetrachloroethylene, was found to be elevated. This is a compound found 
in degreasing agents used to clean equipment.
    In 1994, CDC collaborated with the Mississippi Department of Health 
and the Department of Veterans Affairs (VA) on an assessment of reports 
of adverse birth outcomes among members of two Mississippi National 
Guard Units that served in the Gulf War. This investigation found no 
increase above expected rates in the total number of birth defects, or 
the frequency of premature birth and low birth weight. The frequency of 
other health problems such as respiratory infections, gastroenteritis, 
and skin diseases among children born to these veterans also did not 
appear to be elevated. Due to the small sample size, this investigation 
was unable to assess individual categories of birth defects.
    In 1994, CDC initiated an epidemiologic study of Gulf War veterans 
from Iowa. The Iowa study, conducted in collaboration with the Iowa 
Department of Public Health and the University of Iowa, was one of the 
first population-based epidemiologic studies to document that Gulf War 
veterans are reporting more medical and psychiatric conditions than 
their non-deployed military peers. In fact, this study was recently 
described by IOM as ``perhaps the strongest study on Gulf War veterans' 
experience of symptoms related to deployment in the Gulf.'' The 3,695 
subjects who completed this study were selected from a larger 
population of almost 29,000 military personnel who listed Iowa as their 
home of record. Furthermore, the subjects in this study were 
specifically selected to represent individuals from all four branches 
of the military, and include both regular military personnel and 
National Guard and reservists. Seventy-six percent of the eligible 
study subjects completed the detailed telephone interviews. This study 
is also one of the first controlled epidemiological studies to evaluate 
the health consequences of the Gulf War. The study included a carefully 
selected comparison group of military personnel who were not deployed 
to the Persian Gulf but who served during the time of the Gulf War. The 
Iowa study found that the Gulf War military personnel were more likely 
than those who did not serve in the Gulf War to report symptoms 
suggestive of cognitive dysfunction, depression, chronic fatigue, post-
traumatic stress disorder, and respiratory illness (asthma and 
bronchitis). The conditions identified in this study appear to have had 
a measurable impact on the functional activity and daily lives of these 
Gulf War veterans. Among Gulf War veterans, minimal differences were 
observed between the National Guard or reserve troops and the regular 
military personnel. The results of the Iowa study were published in the 
``Journal of the American Medical Association'' in 1997.
    More recently the Iowa data has been examined to determine whether 
the health complaints of Gulf War veterans represent a novel illness 
unique to service in the Persian Gulf. We assumed that if there was a 
Gulf War syndrome, the symptom pattern would vary between the deployed 
veterans and the non-deployed controls. Although Gulf War veterans 
reported nearly every symptom more often than those who did not deploy 
to the Gulf, we found that Gulf War veterans and non-deployed controls 
had the same patterns of symptoms suggesting that the health complaints 
of Gulf War veterans are similar to those of the general military 
population and are not consistent with the existence of a unique Gulf 
War syndrome. This study was published earlier this year in the 
``American Journal of Medicine.''
    Also in 1994, CDC initiated a study of Air Force personnel. This 
study organized symptoms reported by Air Force Gulf War veterans into a 
working case definition, characterized clinical features, and evaluated 
risk factors. The cross-sectional questionnaire was sent to 3,723 
currently active volunteers from four Air Force populations. Clinical 
evaluations were performed on 158 Gulf War veterans from one unit, 
irrespective of health status. A case was defined based on reporting 
one or more chronic symptoms from at least 2 of 3 categories (fatigue, 
mood-cognition and musculoskeletal) and was further characterized as 
mild-to- moderate or severe depending on the severity of the reported 
symptoms. The prevalence of mild-to-moderate and severe cases were 39 
percent and 6 percent, respectively, among 1,155 Gulf War veterans 
versus 14 percent and 0.7 percent among 2,520 non-deployed veterans. 
Fifty-nine (37 percent) clinically evaluated Gulf War veterans were 
non-cases, 86 (54 percent) were mild-to-moderate cases and 13 (8 
percent) were severe cases. The key observation of the study was that 
Air Force Gulf War veterans were significantly more likely to meet 
criteria for severe and mild-to-moderate illness than were non- 
deployed personnel. There was no association between the chronic 
multisymptom illness and risk factors specific to combat in the Gulf 
War (month of season of deployment, duration of deployment, duties in 
the Gulf War, direct participation in combat, or locality of Gulf War 
service). The finding that 15 percent of non-deployed veterans also met 
illness criteria was equally important and suggests that the 
multisymptom illness observed in this population is not unique to Gulf 
War service. The clinical evaluation component of the study found that 
neither mild-to-moderate nor severe cases were associated with 
clinically significant abnormalities on physical examination or routine 
laboratory tests. However, Gulf War veterans classified as having mild-
to-moderate and severe illness had a significant decrease in 
functioning and well-being compared with non-cases. The results from 
this study were published in CDC's ``Morbidity and Mortality Weekly 
Report'' in 1995 and in the ``Journal of the American Medical 
Association'' in 1998.
    Subsequent analyses of data from the Air Force study have examined 
the association between physical, chemical, and emotional deployment 
stressors reported by Gulf War veterans and the development of chronic 
multisymptom illness following the war. The illness defined in this 
study was found to be related to reporting pyridostigmine bromide use, 
insect repellent use, injuries that required medical attention, and a 
belief that biological or chemical weapons had been used. These 
findings were published earlier this year in the ``Journal of Nervous 
and Mental Disorders.''
    CDC is currently funding a follow-up to the Iowa study focusing on 
evaluating self-reported symptoms of asthma. This study involves a 
detailed clinical evaluation of a sample of subjects who completed the 
initial telephone survey. This evaluation includes a physical 
examination; tests of lung functioning; questions regarding medical, 
occupational, and exposure history; assessment of functional status and 
quality of life; and assessment of psychiatric history and personality 
functioning. The examinations are being conducted at the University of 
Iowa Hospitals and Clinics in Iowa City, Iowa. This study is in its 
final phases of data collection.
    The University of Iowa has also been funded by DOD to conduct 
validation studies of additional health outcomes among participants of 
the telephone survey. These include validation of depression, cognitive 
dysfunction, and fibromyalgia. CDC is providing technical assistance to 
DOD and the University of Iowa for this study.
    We are also funding the Boston University School of Public Health 
to conduct a study examining the relationship between cognitive 
function and symptom patterns among Gulf War veterans. In one component 
of this study, functional magnetic resonance imaging (fMRI) is being 
used to examine possible differences in brain activation patterns 
between Gulf War veterans and era controls with different levels of 
symptoms. A second component of the study is using a new data-driven 
mathematical technique, Logical Analysis of Data, to examine how Gulf 
War veterans' symptoms cluster together. This may provide useful 
information for determining etiology or for developing a working case 
definition. Finally, this study also includes a component examining the 
neuropsychological functioning of a sample of Danish Gulf War troops. 
Investigators are currently in the data collection phase for the fMRI 
component of this study and in the data analysis phase for the other 
two components. We anticipate that this study will be complete by the 
end of this year.
    Finally, CDC is funding the University of Medicine and Dentistry of 
New Jersey-Robert Wood Johnson Medical School to conduct a study 
examining case definition issues. The study will assess the persistence 
and stability of Gulf War veterans symptoms over time, compare the 
performance of data-driven case definitions to existing definitions for 
medically unexplained symptoms, and examine the role of psychiatric 
conditions in Gulf War veterans' unexplained illnesses. We originally 
expected that this study would be completed in late 2000, however the 
process of protocol development and clearance took somewhat longer than 
we anticipated. Thus, we expect that this study will require an 
additional year to complete.
    CDC is also collaborating with DOD and VA on a number of projects 
including a study of health outcomes among Saudi Arabia National Guard 
members and a study of Amyotrophic Lateral Sclerosis (ALS) among Gulf 
War veterans. This collaboration has included providing input on study 
protocols, reviewing human subjects issues, and assisting in laboratory 
assessments.

                      RESEARCH PLANNING CONFERENCE
    CDC, in collaboration with other the Office of Public Health and 
Science, the National Institutes of Health (NIH), and the Agency for 
Toxic Substances and Disease Registry (ATSDR), recently sponsored a 
conference to develop future Gulf War research recommendations. On 
February 28 through March 2, 1999, CDC brought together scientists, 
clinicians, veterans, veterans' service organizations, Congressional 
staff, and other interested parties to discuss and make recommendations 
regarding the direction of future research on undiagnosed illnesses 
among Gulf War veterans and their links with multiple chemical and 
environmental exposures.
    Concurrent workgroups were convened in order to develop research 
recommendations in four areas: pathophysiology, etiology, and 
mechanisms of action; assessment and diagnosis of illnesses; treatment; 
and prevention of illnesses in future deployments. This conference 
highlighted the importance of including veterans in the process of 
planning and implementing research. Veterans and scientists alike 
expressed that they found the process useful and that future similar 
efforts should be encouraged. A report was released earlier this year 
that summarized the outcome of each of the four workgroup sessions. The 
recommendations developed at this conference have been shared with the 
interagency Research Working Group and need to be considered in light 
of the existing research portfolio in order to avoid unnecessary 
duplication of efforts. We are currently developing a call for research 
proposals that will build on the recommendations developed during the 
conference. We would specifically like to address the issue of health 
risk communication and the development of more effective methods for 
delivering deployment-related health information.

                 ASSESSMENT OF FEDERAL RESEARCH EFFORT
    The Federal research portfolio on Gulf War veterans' illnesses has 
been managed by the Research Working Group of the Persian Gulf Veterans 
Coordinating Board and in the near future will be managed by the 
Military and Veterans' Health Coordinating Board. Various agencies 
within HHS, such as CDC, NIH, and ATSDR, have participated in the 
interagency effort to coordinate research, however the majority of this 
research has been funded by DOD and VA. To date there have been 192 
federally-funded research projects on Gulf War veterans' illnesses. 
These projects represent a broad spectrum of research efforts, ranging 
from small pilot studies to large-scale epidemiology studies addressing 
mechanistic, clinical, and epidemiological issues. Similar efforts have 
been initiated in other coalition countries, most notably in the United 
Kingdom and Canada. Many of the projects are ongoing and we eagerly 
await the results of these studies. In addition to the Federal research 
effort, numerous independent review panels and expert committees, such 
as the IOM committees, have evaluated the available data on Gulf War 
veterans' illnesses. Despite these extensive research and review 
efforts, many questions remain regarding the health impact of the Gulf 
War. However, these remaining questions reflect the complexity of 
assessing and predicting the health impact of military deployments. 
Despite this complexity, the federal research effort continues in an 
effort to uncover the causes of illnesses among Gulf War veterans so 
that effective treatment approaches can be developed and similar 
illnesses in future deployments can be prevented.
    Mr. Chairman, this concludes my testimony. I would be happy to 
answer any questions the Subcommittee may have.
STATEMENT OF ROBERT G. CLAYPOOL, M.D., EXECUTIVE 
            DIRECTOR, MILITARY AND VETERANS HEALTH 
            COORDINATING BOARD
    Senator Specter. We now turn to Dr. Robert Claypool, 
Military and Veterans Health Coordinating Board's first 
executive director as of January 1 of this year, responsible 
for directing the activities of the staff which supports the 
co-chairs, namely the Secretaries of Defense, Health and Human 
Services, and VA.
    Thank you for joining us, Dr. Claypool, and we look forward 
to your testimony.
    Dr. Claypool. Mr. Chairman, Senator Hutchison, Senator 
Gorton, it gives me a great pleasure to be able to speak with 
you about the recent Institute of Medicine's report on Gulf war 
health. Before I do that, I would like to take a moment and 
familiarize you with the workings of the Persian Gulf Veterans 
Coordinating Board or PGVCB, which was established in 1994, and 
its role in coordinating Gulf war programs, including research 
on Gulf war veterans' illnesses.
    I would also like to explain that I serve as the executive 
director of this board, as well as the Military and Veterans 
Health Coordinating Board or MVHCB, both of which, as you 
mentioned, Mr. Chairman, are co-chaired by the Secretaries of 
Defense, Health and Human Services, and Veterans Affairs. 
Whereas the PGVCB was established to focus on Gulf war 
veterans' issues, the MVHCB was built on the success of the 
Persian Gulf Board and looks ahead to enhance military 
personnel and veterans' health in future deployments. We are 
currently working on a plan to formally incorporate the 
functions and missions of the Persian Gulf Board into the 
Military and Veterans Health Coordinating Board.
    On August 31, 1993, prior to the establishment of the 
Persian Gulf Veterans Coordinating Board, and in response to 
section 707 of Public Law 102-585, President Clinton designated 
the Secretary of VA to coordinate research funded by the 
executive branch of the Federal Government into the health 
consequences of service in the Gulf war. VA carries out its 
research coordinating role through the auspices of the Research 
Working Group of the PGVCB.
    Each department's research management program for Gulf war 
veterans' illnesses has been linked through an overall policy 
and management coordination effort carried out by the Research 
Working Group. The Research Working Group makes recommendations 
for research funding through the management authority that each 
department maintains over its scientists and its scientific 
program managers who are responsible for research and its 
budgetary process.
    In addition, each department has its own appropriation for 
biomedical research program. The PGVCB and the three working 
groups, including the Research Working Group, have no 
independent budget authority. Dr. Feussner has already provided 
specific information about the PGVCB research activities.
    I mentioned that three different working groups support the 
PGVCB. These working groups are made up of members of the 
Department of Defense, the VA, and HHS. The PGVCB clinical 
working group oversees accomplishments related to medical care 
and clinical assessment, including coordinating the efforts 
between DOD's Comprehensive Clinical Evaluation Program or CCEP 
and the VA's Gulf war Health Registry, providing comparable 
clinical assessment questionnaires and physical and clinical 
laboratory examinations for each program.
    Under the purview of the PGVCB, educational tools and 
programs were developed and medical articles were published to 
assist clinicians caring for Gulf war veterans and to help 
education patients and the public about Gulf war-related health 
issues. The PGVCB clinical working group became a model for 
exchanging ideas and progress between the three departments.
    In addition, a comprehensive health risk communication 
guide was developed for use by each department to more 
effectively inform military personnel, veterans and their 
families of health-related issues associated with the Gulf war, 
as well as with future deployments.
    The third working group, the Disability and Benefits 
Working Group or DBWG, developed guidelines sensitive to 
legally required documentation. Links were formed between the 
Department of Defense and the VA to facilitate a smoother 
transfer of health-related information between the two 
departments. The DBWG has also addressed the need for 
compensation for other serious conditions that have been 
diagnosed in some Gulf war veterans, such as amyotrophic 
lateral sclerosis or ALS.
    Regarding the IOM study, I feel that the report is a 
comprehensive assessment of the peer-reviewed scientific 
literature. Its conclusions are consistent with my working 
knowledge of these exposure agents, as well as with the 
conclusions of previous review groups, such as the Presidential 
Advisory Committee on Gulf war veterans' illnesses. The IOM 
committee rendered opinions as to the causal or associative 
relationship between these agents and adverse health outcomes. 
It pointed out that detailed exposure information would 
facilitate the ability to link observed health concerns with 
those exposures.
    In addition to other factors, I agree that knowing who was 
exposed to how much of what agent when and where are important 
data elements. Documentation of health encounters capturing 
personal exposure, and comprehensive environmental surveillance 
are all part of total medical situational awareness. This 
cognizance has become an essential component of deployment 
health.
    The Military and Veterans Health Coordinating Board, which, 
as I mentioned, will include the functions of the Persian Gulf 
Veterans Coordinating Board, is working through the Deployment 
Health Working Group to assess, coordinate, and make 
recommendations that will resolve this kind of data deficiency.

                           PREPARED STATEMENT

    As to the specific recommendations made in the IOM report 
regarding research needs, Dr. Feussner, as noted the chair of 
the RWG, has addressed these recommendations in detail in his 
testimony.
    Mr. Chairman, thank you for the opportunity to speak with 
your committee today.
    Senator Specter. Thank you very much, Dr. Claypool.
    [The statement follows:]
                Prepared Statement of Robert G. Claypool
    Mr. Chairman and members of the Subcommittee, thank you for this 
opportunity to speak with you today about the recent Institute of 
Medicine's (IOM) report on Gulf War Health, which examines possible 
associations between some of the agents to which Gulf War veterans may 
have been exposed and their potential for adverse health effects. 
Before I do that I would like to take a moment and familiarize you with 
the workings of the Persian Gulf Veterans Coordinating Board (PGVCB), 
which was established in 1994, and its role in coordinating Gulf War 
programs including research on Gulf War veterans' illnesses. I would 
also like to explain that I serve as the Executive Director of this 
Board as well as the Military and Veterans Health Coordinating Board 
(MVHCB), both of which are Co-Chaired by the Secretaries of Defense, 
Health and Human Services, and Veterans Affairs. Whereas the PGVCB was 
established to focus on Gulf War Veterans' issues, the MVHCB was built 
on the success of the PGVCB and looks ahead to enhance military 
personnel and veterans' health in future deployments. We are currently 
working on a plan to formally incorporate the functions and missions of 
the PGVCB into the MVHCB.
    On August 31, 1993, prior to the establishment of the Persian Gulf 
Veterans Coordinating Board, and in response to section 707 of Public 
Law 102-585, President Clinton designated the Secretary of VA to 
coordinate research funded by the Executive Branch of the Federal 
Government into the health consequences of service in the Gulf War. VA 
carries out its research-coordinating role through the auspices of the 
Research Working Group (RWG) of the PGVCB. Each Department's research 
management program for Gulf War veterans' illnesses research has been 
linked through an overall policy and management coordination effort 
carried out by the RWG. The RWG makes recommendations for research 
funding through the management authority that each department maintains 
over its scientists and its scientific program managers who are 
responsible for research and its budgetary process. In addition, each 
Department has its own appropriation for biomedical research programs. 
The PGVCB and its three working groups, including the RWG, have no 
independent budget authority. Dr. John Feussner has provided specific 
information about the PGVCB RWG research activities.
    I have mentioned that three different working groups support the 
PGVCB. These working groups are made up of members of DOD, VA, and HHS. 
The PGVCB Clinical Working Group (CWG) oversees accomplishments related 
to medical care and clinical assessment including coordinating the 
efforts between DOD's Comprehensive Clinical Evaluation Program (CCEP) 
and the VA's Gulf War Health Registry; providing comparable clinical 
assessment questionnaires; and physical and clinical laboratory 
examinations for each program. Under the purview of the PGVCB, 
educational tools and programs were developed and medical articles were 
published to assist clinicians caring for Gulf War veterans and to help 
educate patients and the public about Gulf War-related health issues. 
The PGVCB Clinical Working Group became a model for exchanging ideas 
and progress between the three departments. In addition, a 
comprehensive health-risk communication guide was developed for use by 
each department to more effectively inform military personnel,

    The third working group, the PGVCB's Disability and Benefits 
Working Group (DBWG), developed guidelines sensitive to legally 
required documentation. Links were formed between DOD and the VA to 
facilitate a smoother transfer of health-related information between 
the two departments. The DBWG has also addressed the need for 
compensation for other serious conditions that have been diagnosed in 
some Gulf War veterans, such as amyotrophic lateral sclerosis (ALS).
    Regarding the IOM study, I feel that the report is a comprehensive 
assessment of the peer-reviewed, scientific literature. Its conclusions 
regarding the evidence for both transient and long-term health effects 
associated with sarin, depleted uranium, pryidostigmine bromide, and 
vaccines are consistent with my working knowledge of these exposure 
agents as well as the conclusions of previous review groups, such as 
the Presidential Advisory Committee on Gulf War Veterans' illnesses. 
The committee rendered opinions as to the causal or associative 
relationship between these agents and adverse health outcomes. It 
pointed out that detailed exposure information would facilitate ability 
to link observed health concerns with those exposures. In addition to 
other factors, I agree that knowing who was exposed to how much of what 
agent when and where are important data elements. Documentation of 
health encounters, capturing personal exposure, and comprehensive 
environmental surveillance are all part of total medical situational 
awareness. This cognizance has become an essential component of 
deployment health. The Military and Veterans Health Coordinating Board 
(MVHCB), which includes the functions of the Persian Gulf Veterans 
Coordinating Board, is working through the Deployment Health Working 
Group to assess, coordinate, and make recommendations that will resolve 
this kind of data deficiency.
    As to the specific recommendations made in the IOM report regarding 
future research needs, I am confident that the Gulf War research 
program will adequately address each recommendation. Dr. Feussner, the 
Chair of the PGVCB RWG, addresses each of the IOM recommendations in 
detail in his testimony presented here today.
    Mr. Chairman, thank you, again for the opportunity to speak with 
the Subcommittee today.

    Senator Specter. We will now proceed with questions from 
the senators. And we will have 5-minute rounds.
    Dr. Barrett, the Iowa study conducted by the Centers for 
Disease Control has been summarized as finding that the Gulf 
war military personnel were more likely than those that did not 
serve in the Gulf war to report symptoms suggestive of 
cognitive dysfunction, depression, chronic fatigue, post-
traumatic stress disorder, and respiratory illness.
    When you have a finding more likely than not, that 
satisfies the civil burden of proof, preponderance of the 
evidence. Does that in your professional judgment establish a 
finding that exposure to these toxic substances did in fact 
cause Gulf war syndrome?
    Dr. Barrett. Well, I think the first point that is 
important is the Iowa study was conducted as a telephone 
survey. So it did not involve, at that point, doing any 
physical examinations. And it was just reporting on trying to 
get an idea----
    Senator Specter. We have a lot of telephone surveys in this 
day and age. That is about all we do. They call them polls----
    Dr. Barrett. Well, there is some----
    Senator Specter [continuing]. In one respect.
    Dr. Barrett. There is follow-up that is going on.
    Senator Specter. Excuse me. What is wrong with the 
telephone survey?
    Dr. Barrett. Well, the point of the Iowa study was to get a 
handle on the prevalence and adverse health outcomes among 
those who went to the Gulf in comparison to those who did not. 
So the point was to assess a variety of different types of 
health outcomes. What we are currently doing is follow-up on 
that cohort to bring people in to do objective testing to see 
how the self report of symptoms compares with findings on 
physical examinations.
    Senator Specter. How many people were surveyed?
    Dr. Barrett. There were approximately 3,700 people who were 
surveyed.
    Senator Specter. Well, that is a pretty good-sized survey. 
The concern that I have is when are we going to finish the 
studies, and when are we going to finish the task. This is a 
300-page report, which cost a lot of money, conducted by the 
Veterans Affairs Committee in the 105th Congress. And we came 
to the conclusion here--we will try to talk over that noise.
    The conclusion here was that the evidence, the medical 
evidence, was not really very definitive. But the practical 
sense consequence was that there is a pragmatic causal 
relationship between exposure to these toxic substances and all 
of these ailments.
    Senator Hutchison commented about that in her remarks. I 
certainly have found that in a series of hearings in 
Pennsylvania and people that we have talked to here.
    Dr. Rostker, as a principal DOD official in charge----
    Dr. Rostker. We----
    Senator Specter. You have not gotten the question yet, Dr. 
Rostker.
    How many more studies are we going to have? What is the 
point? Have we not really already established in a pragmatic 
sense the cause and effect of the exposure to these toxic 
substances in Gulf war syndrome?
    Dr. Rostker. Sir, we recognize that those who served in the 
Gulf have a higher rate of reporting illnesses. We do not 
understand what that is associated to. You talked about a 
number----
    Senator Specter. What do you mean, not associated to? They 
served in the Gulf war.
    Dr. Rostker. And you defined the Gulf war in terms of a 
number of toxins. An additional factor in the Gulf war was 
stress. There are other unknown factors that could have been 
attributed to the Gulf war. I do not dispute that those who 
served in the Gulf war are reporting illness at a higher rate. 
I cannot make the conclusion that you are willing to make, that 
it is because of exposure to a specific list, definitive list, 
of toxins.
    Senator Specter. Dr. Barrett testified that there is a 
``lack of objective exposure data.'' Well, that is never going 
to improve. We are never going to have any better data after 
the year 2000 from what happened in 1991.
    Dr. Feussner, final question. My yellow light is about to 
expire to a red light. As a practical consequence, are the Gulf 
war veterans who complain of this long list of maladies being 
treated and served by the Veterans Administration on the 
current state of the record without a greater finding of cause 
and effect?
    Dr. Feussner. Yes, I think that is correct. I think what 
the Iowa study--well, to answer your question first, I think 
that veterans who are presenting to VA with a variety of 
symptoms are having those symptoms treated.
    In addition to that, VA and DOD, in addition to the 
standard treatment that you might receive for some of these 
symptoms and clinical problems, the DOD and VA have mounted two 
specific treatment trials that look at other aspects of Gulf 
war veterans' illness, one looking at the use of antibiotics to 
treat the illness complex, and another looking at behavioral 
therapy and exercise therapy. So that in addition to standard 
therapy, there are clinical trials going on looking at new 
treatment strategies. The clinical trials will be finished next 
summer. They involved hundreds, and even thousands, of 
veterans.
    I think you are correct, that information about exposures 
is never going to be better, certainly could not be better 10 
years after the exposure took place. That seriously compromises 
the ease with which the research effort can go forward in 
identifying a causal relationship.
    The other issue that is difficult is that the IOM noted, 
for example with uranium, that in populations that have known 
exposures for known periods of time, it frequently will take 
decades to track those patients because of the latency of 
illness developing after a known exposure. In the Gulf war 
veteran cohort, we are dealing with unknown doses of exposures.
    But those doses are likely to be low and of short duration. 
It is more difficult to tease out long-term consequences of 
low-dose and short-duration exposures than acute effects of 
known high-dose exposures.
    Senator Specter. Thank you very much, Dr. Feussner. My red 
light went on in the middle of your answer. So I am going to 
yield now to Senator Hutchison.
    Senator Hutchison. Well, thank you, Mr. Chairman. Are you 
going to allow a second round, also?
    Senator Specter. I do not think so. But take what time you 
need now, Senator.
    Senator Hutchison. OK. I have several questions of 
different members of the panel. And I wanted to establish a 
couple of things. Let me start with Dr. Barrett.
    The Centers for Disease Control has a classic manual for 
field investigations. It is in a book, actually, entitled, 
Field Epidemiology. I am sure you are familiar with this. I 
understand that the classic approach that the CDC uses is 
outlined in this book. And it is fairly simple. You take up--
first you get a case definition of your disease. You find a 
convenient group where you separate them into people who have 
symptoms and people who do not who were in the same group. Then 
you analyze the data, and you find out which risk factors were 
effective. And then you go through the steps.
    And it is my understanding that this is how you found the 
cause of toxic shock syndrome and Legionnaire's disease. I want 
to ask you if you think that enough of this kind of approach 
has been done for the Desert Storm disease.
    Dr. Barrett. Let me discuss CDC's Air Force study, because 
I think it follows this classic model that you are talking 
about. It was conducted at the end of 1994. There was some 
thought that there was excessive illness among a particular Air 
National Guard unit in the State of Pennsylvania. And the State 
of Pennsylvania, along with the Department of Veterans Affairs 
and the Department of Defense, invited the CDC in to do an 
investigation. CDC then followed the classic model of first 
going in and doing a very careful clinical examination of the 
most characteristic patients. That process found that veterans 
were reporting symptoms, such as fatigue and aches and pains. 
But the initial evaluations, clinical evaluations, were not 
able to identify any findings on physical examination or 
routine laboratory tests.
    The next step that we did was to collect information on 
those who went to the Gulf versus those who did not go to the 
Gulf, collecting much more detailed information about the types 
of symptoms that were being reported and trying to get 
information on the various types of experiences that occurred 
while in the Gulf. This included looking at this particular 
index unit, but also comparing three different control units.
    That step was used to develop a working case definition. I 
think what was important that came out of this case definition 
is that illness was not unique to those who were deployed to 
the Gulf. In fact, about 45 percent of those who were deployed 
to the Gulf met this case definition. About 15 percent of those 
who did not go to the Gulf also met the case definition. So 
clearly, we are dealing with something that is not specific to 
deployment in the Gulf.
    They then took a----
    Senator Hutchison. In that particular unit. But do you 
think this has been employed throughout the United States with 
other groups that--one in seven is not psychosomatic. There is 
something here. And I do not question how much money we have 
spent. I do question that we do not have definitive results.
    Dr. Barrett. Right.
    Senator Hutchison. And I do question that we do not seem to 
be willing to say that there is a Desert Storm disease and then 
go forward with the techniques that we need to use to find--
maybe there are several different causes. I think Dr. Haley's 
examinations have shown that there might be three factors that 
would go into one disease. But it seems like we could get 
beyond the simplicity of saying it is all amorphous, and we 
just cannot say that there is a syndrome here. One in seven, I 
am willing to state for the record is a syndrome, one in seven.
    Dr. Barrett. This has also been looked at in the Iowa study 
as well, this issue of is there a syndrome. And----
    Senator Hutchison. Iowa and Pennsylvania. Are there others?
    Dr. Barrett. And it has been--the idea of whether there is 
a syndrome has been looked at in at least four different 
studies. The approach that has been used to identify a 
definition is a little different than is used in classical 
approaches, that usually when you do a clinical investigation, 
it can point you in the direction of what is the source of the 
illness and what is the agent that you are looking at. In this 
case, those types of clinical evaluations are not pointing us 
in any particular direction.
    So people have gotten somewhat innovative and have turned 
to statistical approaches, and specifically factor analysis. 
And that has been used in several different studies. The Iowa 
study just recently published findings on its data and finds, 
very similar to what the Air Force study found, that when you 
look at both Gulf war veterans and nondeployed veterans, you 
are finding similar clusterings of symptoms. So it does not 
appear that this is representing a unique syndrome.
    Senator Hutchison. Well, let me just say that I think your 
methods have been proven in the past. And maybe 4 in the last 
10 years may not be enough. And I would like to see us perhaps 
pursue some of that.
    Let me ask another question to Dr. Feussner. And this may 
have an impact on how much cooperation you are getting.
    I understand that you are looking in the very early stages 
of the number of younger Gulf war vets who are coming up with 
Lou Gehrig's disease, and that--I am not being scientific here, 
but that you are beginning to see that maybe there are 40 to 50 
cases in a group of Gulf war veterans versus the general 
population, which would be 20 or 25, enough that you are 
pursuing, as I understand, to see if there is a higher 
incidence.
    But then I get a copy of the VA research consent form, 
which says ``if you are receiving compensation for an 
undiagnosed illness,'' which is how many of the people who have 
Desert Storm syndrome are classified, and they are getting 
compensation and treatment, because it is undefined, 
``participation in our study may result in the loss of those 
benefits, if you are diagnosed with Lou Gehrig's disease. VA 
regulations require that this study consent form be filed in 
the veteran's VA medical records. Therefore, we can't guarantee 
VA benefits. And the administration will not learn of any of 
this information nor that any benefits that you may be 
receiving will not be affected as a result of that knowledge.''
    Now, I just want to ask you if you think that there is not 
a double incentive here for people not to participate in a very 
valid question that you are asking to see if perhaps this may 
be causally connected to a debilitating, horrible disease known 
as Lou Gehrig's disease.
    Dr. Feussner. Would you like me to start with the study or 
the consent form, Senator?
    Senator Hutchison. Well, I would like for you to answer----
    Dr. Feussner. OK.
    Senator Hutchison [continuing]. How this consent form would 
allow you to have a study.
    Dr. Feussner. Well, let me say that a Member of Congress 
and I met with a group of veterans in Atlanta in early March. 
And the veterans raised concern about this question of Lou 
Gehrig's disease. Amyotrophic lateral sclerosis is a very rare 
disease. The prevalence of this disease is about 3 or 4 per 
100,000. It is a very difficult disease to study because it is 
rare, and there is no treatment for this disease.
    The veterans were concerned that there might be an excess 
risk of getting this disease because of their service in the 
Gulf war. What we did as a result of that follow-on, in 
collaboration with DOD, is we planned a national case finding 
study, looking, trying to identify 100 percent of cases of ALS 
in all Gulf war veterans, Gulf-era veterans, the 700,000 that 
were deployed, the 1.4 million that were not. We have just 
begun that process in March/April of this calendar year.
    As we planned that study, we looked at some of the data 
very hard. And the preliminary result was that there was no 
increased rate of ALS among Gulf war veterans. But the 
preliminary observation was flawed, because only cases that 
were already known were looked at.
    And the question is: Well, what if there are cases or 
patients with this that are not known? Then we could 
underestimate, and this initial preliminary result could be 
fallacious. The only way to get at that issue is to try to look 
at all of them.
    The second issue, when we looked at this, is that Lou 
Gehrig's disease is typically a disease of older people. Even 
though Lou Gehrig himself died of this disease in his thirties, 
it is typically an older person's illness. And the age 
distribution in the cases that we had identified was younger 
than we expected. So we decided to go forward and try to answer 
this question definitively.
    We engaged the help of the ALS Association of America to 
help us announce that we were doing this. We published a trial 
in multiple VSO and other magazines. We contacted the American 
Academy of Neurology, et cetera. The complicating factor in 
this is that the Congress passed legislation that awarded 
veterans benefits for having an undiagnosed illness. And the 
risk is--let us say that you are getting benefits because you 
have an undiagnosed illness. And I now examine you, and I 
figure out that you have ALS.
    Senator Hutchison. Yes. Are you going to get around to 
telling me if you are going to give protection----
    Dr. Feussner. Yes.
    Senator Hutchison [continuing]. To these people----
    Dr. Feussner. No.
    Senator Hutchison [continuing]. Or is it something we need 
to do?
    Dr. Feussner. Yes.
    Senator Hutchison. Are you telling me Congress needs to 
say----
    Dr. Feussner. Yes.
    Senator Hutchison [continuing]. Veterans benefits will not 
be denied to people who have Lou Gehrig's disease?
    Dr. Feussner. OK.
    Senator Hutchison. Or should it be--look, I am open.
    Dr. Feussner. No. Let me----
    Senator Hutchison. If we need to make it more general, 
particularly as it results to Desert Storm syndrome, because I 
really think that we have spent $130 million, and we are still 
not willing to declare there is a syndrome here. And if that is 
our fault, you tell me. Because I am willing to do a couple of 
things for accountability.
    Senator Specter, I will ask for his help on this. And we 
will introduce some legislation. And I will talk to Senator 
Warner about it and Senator Stevens. And we will see what we 
can do, if we can get a declaration that there is a Gulf war 
syndrome. And now that we have determined that there is one, we 
are going to cover people's treatment and people who have it, 
and we are not going to deny the evidence that they were 
healthy when they went into the war. I mean, we do not even let 
people who are unhealthy go into a deployment. You know that, 
and I know that.
    So if they came in healthy, and they have symptoms now, and 
we have all the evidence in the world that says it is not just 
stress related, tell me what I need to do. And then let us 
focus on the fact that we have a syndrome, and how can we now 
work for treatment of this and future illnesses.
    Dr. Feussner. The issue with the ALS is very frustrating, 
ma'am. We have tried to gain some relief from the fact that if 
you were made--if you were known to have a diagnosis of ALS and 
were previously awarded benefits for having an undiagnosed 
illness, you would not lose those benefits.
    We have actually met with and briefed Congress on this 
matter. We have informally in those briefings asked for 
legislative relief in that area. The legal folk at VA say there 
is no way to give or to retain benefits when the undiagnosed 
illness becomes diagnosed.
    Now----
    Senator Hutchison. Yes. But if----
    Dr. Feussner [continuing]. Ma'am----
    Senator Hutchison [continuing]. We say there is a Desert 
Storm syndrome, which we have never in all of the papers that 
have been written, we keep saying there is really not one, we 
are trying to keep looking, and everything is different, and we 
cannot put it altogether, if we say there is a Desert Storm 
syndrome, does that not solve it? It may not be that all the 
symptoms are the same.
    But then we can go about determining if there is a 
difference between sarin gas or the vaccinations or the 
different potential causes, if we just admit that one in seven 
people who went over there healthy and who came back with 
syndromes are not psychosomatic.
    Can we not just say, OK, we now have a syndrome? Do not we 
solve that problem? And can we not get on with it? And maybe 
Lou Gehrig's disease is one of the results, but there are 
others as well?
    Dr. Feussner. Well, if I could finish the Lou Gehrig 
disease story. Because we were unable to resolve that issue, 
because of that benefits conundrum, and because we are required 
by the common rule to disclose benefits and potential risks of 
research to people who volunteer to participate in these 
trials, we thought it would be very important to make it 
explicit in the informed consent document that this was an non-
resolved issue and that there was a risk to the veteran that 
their benefits issue might be complicated by that.
    Now--so we are disclosing that information fully to 
veterans. To date, we have had four veterans who have refused 
participation in the trial because they were informed that this 
was a potential risk. We are able to count those. It would be 
best to have relief from this conundrum so that we could study 
all of them. But we are counting the ones who refused to 
participate because of this risk. And we will presume that they 
have ALS. And so if we err in the estimation, we err on the 
high side.
    The problem with declaring that there is a Gulf war 
syndrome is, to follow up what Dr. Barrett said, that the 
research suggests that there is not. And the Senate 
investigation unit----
    Senator Specter. Well, the research does not quite suggest 
that. The research is inconclusive. That is a lot different 
from the research suggesting that it is not.
    Senator Hutchison. And we are saying long term as opposed 
to short term.
    Dr. Feussner. I would agree with you, sir.
    Senator Hutchison. And long term, we have had 9 years. That 
is not long term yet. I do not think that you can say in any 
way, even from the stuff that you put out, which seems to be, 
all of you, to go in that direction, that there really is not 
one. But in fact, there are beginnings of nuggets that say 
there is. And we are not into long term yet, but we have a 
whole lot of evidence that says short term, yes; let us keep 
looking.
    Do you not think that--I mean, have we not learned from the 
mistakes of the past? I mean, even agent orange. Why can the 
Department of Defense not get into the forefront of these 
issues? Why cannot the VA do its job of protecting its 
veterans? And I am not singling you out.
    But I am just saying, why are we consulting lawyers instead 
of focusing our money on what our responsibilities are to our 
veterans, the clear common sense evidence that is before us, 
and saying, you know, we are not a bunch of lawyers, we are a 
bunch of doctors who are required to protect the people that 
are serving our country and the veterans and the retirees?
    It just seems to me that we are getting awfully hung up 
trying to say that one in seven people are psychosomatic when 
we could do a whole lot better.
    Senator Specter. Senator Hutchison----
    Senator Hutchison. I appreciate the time.
    Senator Specter. Senator Hutchison, I was about to 
compliment you for your comments. And I would associate myself 
with your remarks. I do not know what long term is, if 9 years 
is not long term.
    And Dr. Feussner, I do not want to place too much emphasis 
on your comment, but I think it may indicate a predisposition 
when you testify that Gulf war syndrome was not caused by the 
exposure. All of the evidence turns out to be, we are told, 
scientifically inconclusive. And it is sometimes a little hard 
to understand what is sufficient to be conclusive 
scientifically.
    And that is why, when Senator Rockefeller and I finished 
this 300 page report, which had been done--he was ranking at 
Veterans, and I chair--that we concluded that there was a 
causal connection between exposure to these toxic substances 
and Gulf war syndrome.
    And Senator Hutchison puts her finger right on the spot 
when she talks about agent orange. That was the cause celebre 
when I came to the Senate after the 1980 election. And finally 
the Congress took the bull by the horns and established a 
presumption. And we deal on the Veterans Affairs Committee with 
some regularity about legislating presumption. If the doctors 
cannot come to conclusions, Congress can legislation 
presumptions.
    But I think Senator Hutchison puts her finger on the point. 
And that is that the pragmatic conclusion is there is a 
connection. But as long as the veterans are being treated, that 
is the most important part. And I think there is an 
institutional reluctance by DOD and VA and other governmental 
agencies to make concessions which are likely to cost any 
money. That is what it comes down to again and again and again. 
And then the Congress has to make a judgment as to what we 
think fairness and equity is based on all the evidence which we 
have seen.
    Senator Hutchison, you had a lot of good questions, and you 
had some time. But if you need more, you are welcome to it.
    Senator Hutchison. No, Mr. Chairman. I would like to go on 
to the second panel.
    I appreciate that you came. I would ask you, if you would 
just consider that you are the trustees. It is like--Senator 
Specter and I are lawyers, and we know that a trustee has a 
higher duty than just an average person. And I think you are 
the trustees for our military personnel. You are the trustees 
for our veterans. One in seven are suffering. And I just do not 
think we have come to the definitive answer that we should, as 
trustees for them.
    So I would just thank you, Mr. Chairman. You have been very 
kind to let me go forward. I do have about five other 
questions, which I am going to abstain from asking. But I do 
think there is a general view here that is not the right one. 
And I would rather you come to Congress and say: We do want to 
declare this a syndrome. There is just too much evidence. We 
want to go for it. And it is going to cost money. Now we are 
putting it in your lap. You provide us the money. We are going 
to do the research. We are going to target it. We are going to 
declare that these people deserve treatment and compensation.
    And let us make that decision. Because I will guarantee 
you, we will give you the money, if you will declare this a 
syndrome. And let us get to the bottom of it.
    Thank you very much.
    Senator Specter. Thank you very much, Senator Hutchison.
    Thank you very much, Dr. Barrett, Dr. Rostker, Dr. 
Feussner, Dr. Claypool, Dr. Brown.
STATEMENT OF HAROLD C. SOX, JR., M.D., PROFESSOR AND 
            CHAIR, DEPARTMENT OF MEDICINE, DARTMOUTH-
            HITCHCOCK MEDICAL CENTER
ACCOMPANIED BY DR. SAMUEL POTOLIKIO, PROFESSOR OF NEUROLOGY, GEORGE 
            WASHINGTON UNIVERSITY

    Senator Specter. We now turn to our second panel. Dr. 
Harold Sox, since 1998, has served as professor and chairman of 
the Department of Medicine at the Dartmouth Medical School. He 
currently chairs the Institute of Medicine Committee on Health 
Effects Associated with Experiences in the Gulf war. He served 
15 years as a professor at the Stanford University School of 
Medicine earlier in his career.
    Dr. Sox, welcome to the hearing room. And we look forward 
to your testimony.
    Dr. Sox. Thank you, Mr. Chairman and members of the 
committee. I am accompanied by Dr. Samuel Potolikio, who is a 
member of our committee, a neurologist, a professor of 
neurology at George Washington University. And I may turn to 
him for help with some of the questions related to several of 
the exposures that we studied.
    The genesis of our report was a request from the Department 
of Veterans Affairs asking the Institute of Medicine to study 
the available scientific evidence on potentially harmful 
effects to which Gulf war veterans may have been exposed. 
Congress subsequently mandated a similar study, assessifying 33 
specific agents.
    Our committee was charged with assessing the scientific 
literature about potential health effects of chemical and 
biological agents present in the Gulf war theater. We expected 
the Department of Veterans Affairs will use our findings as a 
scientific basis for developing a compensation program for Gulf 
war veterans.
    Our committee was not asked by Senator Byrd's and your 
enabling legislation to examine whether a unique Gulf war 
syndrome exists. We did, however, read the scientific 
literature on Gulf war illnesses. And we were aware of the 
symptoms of these illnesses as we read the literature for 
health effects of the agents that we studied.
    In the first study of the series, the Institute of Medicine 
chose to study the agents that were of most concern to the 
veterans: sarin, pyridostigmine bromide, otherwise known as PB, 
depleted uranium, and the vaccines to prevent anthrax and 
botulism.
    Because there have been very few published studies on Gulf 
war veterans, most of the studies that we examined were about 
exposures in occupational, clinical, and healthy volunteer 
settings. Let us begin with the nerve agent sarin. High doses 
of sarin can cause overstimulation of nerves and muscles within 
seconds or hours, creating symptoms such as severe cramping, 
difficulty breathing, twitching, and heavy sweating. All these 
short-term effects are well-documented. And we ranked this 
evidence as sufficient to establish causality, the highest 
level of evidence.
    The long-term effects of sarin, however, are an entirely 
different story. The evidence is more limited in quantity and 
much weaker. Studies describing three different populations 
exposed to sarin, two involving victims of terrorist attacks in 
Japan and one involving industrial accidents in the United 
States, establish possible links to neurological and 
psychological symptoms that persisted for 6 months or longer.
    In all three studies, however, the patients all had an 
immediate, intense, widespread acute reaction, typical of the 
high levels of exposure to sarin. Among the symptoms that 
persisted over the long run in these patients were fatigue, 
headaches, blurred vision, and symptoms of post-traumatic 
stress disorder. But it is important to remember that people 
who had these long-term symptoms all experienced intense 
symptoms immediately. Because we are dealing with the study of 
only three populations and because we could not rule out 
alternate explanations for the effects, the committee 
categorized these findings as limited or suggestive of an 
association between acute exposure to sarin in high doses and 
long-term effects.
    Few, if any, veterans actually reported symptoms of acute 
exposure to sarin. Therefore, we concerned ourselves with 
possible effects of sarin in doses too small to cause the acute 
reaction. And based on the available evidence, we could not 
form a conclusion about an association between long-term health 
effects and exposure to sarin that are low enough so there were 
no immediate signs or symptoms. Yet research with non-human 
primates gives us a hint that long doses of sarin over long 
periods might create delayed neurological reactions, a finding 
that clearly needs substantiation with further research.
    The second agent that we studied was PB, pyridostigmine 
bromide. There have been many effects of the short-term uses of 
PB. And the committee judged this evidence to be sufficiently 
strong to demonstrate an association between exposure and the 
immediate onset of mild, transient symptoms, a length that has 
been seen consistently in many studies. Long-term effects of PB 
are an entirely different story. There simply was not enough 
evidence to draw any conclusion about PB's long-term effects. 
In other words, we do not know if they occur, and we cannot be 
certain that they do not occur. The author of one series of 
studies has suggested that PB alone or in combination with 
other chemicals could be related to some chronic changes in 
nerve function reported by Gulf war veterans. However, 
weaknesses in the design of these studies made it impossible 
for us to decide if exposure to PB is associated with long-term 
nerve damage. And we recommend further investigation with an 
improved design.
    The third agent was depleted uranium. Health effects of 
natural uranium have been widely investigated, mostly in 
occupational settings. While these studies have shown that 
uranium has either no effect or a very small effect, our 
committee found weaknesses in many of these studies. And we 
could not draw conclusions about exposure to uranium and death 
from a number of diseases, including lymphatic or bone cancer.
    We were able, however, to arrive at more certain 
conclusions regarding kidney disease and lung cancer. Based on 
the study of the Baltimore cohort of veterans, we concluded 
that there is limited evidence of no association between kidney 
disease and exposure to uranium. And we based this study on 
several consistent studies that showed good kidney function 
despite continuous exposure to uranium as it dissolve from 
uranium fragments imbedded in body tissues.
    Similarly, at low levels of exposure to uranium, we found 
limited evidence of no effect, or no association, with death 
from lung cancer. At higher levels of exposure, the evidence 
did not permit any conclusion.
    Finally--and I will be wrapping up shortly--our committee 
considered the vaccines given to prevent anthrax and botulism. 
Based on our review of the scientific literature, we concluded 
that the evidence is sufficient to demonstrate an association 
between these vaccines and subsequent long-term--short-term, 
correction--local and systemic effects similar to those 
associated with any vaccination, such as the ones that people 
in the audience have received.
    When we sought evidence for more lasting effects, we did 
not find any published peer review studies that systematically 
followed subjects over the long term, a situation that is not 
unusual as vaccines are seldom monitored for adverse effects 
over long periods of time.
    Some have questioned whether several vaccines in 
combination could result in health effects that would not be 
seen with a single vaccine alone. Although we did find some 
evidence, research, on cumulative effects of combinations of 
vaccines, the shortcomings of these studies made it impossible 
for us to draw a strong conclusion.

                           PREPARED STATEMENT

    The IOM is beginning the second phase of this study, in 
which it will examine the literature on the health effects of 
pesticides and solvents. Plans for future IOM studies include 
completion of studies of the remaining agents from those listed 
in enabling legislation. The IOM will also update its prior 
studies as new studies enter the published literature.
    Thank you for your attention.
    Senator Specter. Thank you very much, Dr. Sox. And thank 
you for your work with the Institute of Medicine.
    [The statement follows:]
                Prepared Statement of Harold C. Sox, Jr.
    Good morning, Mr. Chairman and members of the committee. My name is 
Harold Sox. I am a professor and chair of the Department of Medicine at 
Dartmouth-Hitchcock Medical Center in Lebanon, New Hampshire. I chaired 
the Institute of Medicine Committee on Health Effects Associated with 
Exposures During the Gulf War, which released its report on Thursday, 
September 7. I appreciate the opportunity to provide testimony to you 
today based on the findings of this report. I am accompanied by Dr. 
Samuel Potolicchio, a member of the IOM committee and Professor in the 
Department of Neurology at George Washington University Medical Center.
    The genesis of the report was a request from the Department of 
Veterans Affairs, asking the Institute of Medicine to study the 
available scientific evidence on potentially harmful agents to which 
Gulf War veterans may have been exposed. Congress subsequently mandated 
a similar study listing 33 specific agents for study. Thousands of Gulf 
War veterans have experienced chronic, unexplained health problems, and 
are asking whether these agents might be responsible.
    It is important to clarify the scope of the committee's work. The 
committee was charged with assessing the scientific literature 
regarding potential health effects of chemical and biological agents 
present in the Gulf War. The findings of the report will be used by the 
Department of Veterans Affairs as a scientific basis for developing a 
compensation program for Gulf War veterans. The committee was not asked 
to examine whether a unique Gulf War syndrome exists or to review or 
evaluate the literature on Gulf War syndrome or illnesses. 
Additionally, it was not asked to make judgments regarding the 
veterans' levels of exposure to the putative agents as there is an 
assumption of exposure for Gulf War veterans. For the first study of 
the series, the Institute of Medicine chose to study the agents of most 
concern to the veterans: sarin, pyridostigmine bromide (PB), depleted 
uranium, and the vaccines to prevent anthrax and botulism.
    Because of the limited studies in Gulf War veterans, most of the 
studies that we examined involved exposures in occupational, clinical, 
and healthy-volunteer settings. We carefully assessed each study's 
quality, limitations, and applicability.
    When it comes to the long-term health effects of these substances, 
the bottom line is we simply don't know enough to say whether there is 
a connection between exposure to these agents or combinations of agents 
and specific health outcomes that remain long after the exposure. At 
most, we found some very limited evidence that might suggest a possible 
connection with the nerve agent sarin. These effects, if they truly 
exist, occur in individuals whose dose was large enough to cause acute 
symptoms immediately after the exposure. It will take further research 
to explore this relationship.
    Let's begin with the nerve agent sarin. It is so potent that as 
little as 100 milligrams--about two drops--can cause convulsions and 
death. As a gas, roughly 50 milligrams can be fatal. Lower doses can 
cause overstimulation of nerves and muscles within seconds or hours, 
creating symptoms such as severe cramping, difficulty breathing, 
twitching, and heavy sweating. In the more severe cases, these symptoms 
are widespread and affect many parts of the body.
    All of these short-term effects are well-documented, and we ranked 
the evidence as sufficient to establish causality, the highest level of 
evidence. In part, this means many studies have strongly, repeatedly, 
and consistently linked these acute health effects and exposure to 
sarin, and that the greater the exposure, the greater the effect. But 
the long-term effects of sarin are a very different story. The evidence 
is far more limited and much weaker. Studies describing three different 
populations--two involving victims of terrorist attacks in Japan and 
one involving industrial accidents in the United States--linked 
neurological and psychological symptoms that persisted for six months 
or longer. In one of these studies, some symptoms persisted for up to 
three years, the longest that any of the subjects were followed. In all 
three study populations however, the doses of sarin were high enough to 
trigger an immediate, intense, widespread, and acute reaction. Among 
the conditions that persisted over the long term were fatigue, 
headaches, blurred vision, and symptoms of post-traumatic stress 
disorder. In other words, people who had long-term symptoms were the 
ones who had experienced intense symptoms immediately.
    Because we are dealing with studies of only three populations here, 
and because we could not rule out other explanations for the effects, 
the committee categorized these findings as limited or suggestive of an 
association--well shy of the evidence needed to establish a possible 
link, but warranting further investigation. In this case, we recommend 
research to track the health of the victims of sarin attacks in Japan, 
since they provide the best opportunity for conducting controlled 
studies.
    Based on available research, we could not form a conclusion about 
an association between long-term health effects and exposure to lower 
doses of sarin--low enough so that there were no immediate signs or 
symptoms. Yet, research with nonhuman primates gives a hint that low 
doses of sarin over long periods may create delayed, neurological 
reactions. More research is needed to substantiate this finding. We 
recommend that such studies be pursued.
    The second agent we considered was the drug pyridostigmine bromide. 
It is routinely used to treat patients with myasthenia gravis, a 
disease that causes weakening of the muscles. PB does have side 
effects. It is known to cause mild, tolerable, and transient 
gastrointestinal and muscular symptoms. In the Gulf War, troops were 
given packets of PB tablets to take in advance of a chemical weapons 
attack in order to blunt the effects of nerve agents. The recommended 
doses were lower than those commonly used by doctors to treat patients 
with myasthenia gravis.
    There have been many studies of the short-term effects of PB, and 
the committee judged this evidence to be sufficiently strong to 
demonstrate an association between exposure and the immediate onset of 
mild, transient symptoms. Many studies have repeatedly and consistently 
supported this linkage. Long-term side effects of PB are another story. 
There simply was not enough evidence to draw any conclusion about PB's 
long-term effects. In other words, we don't know if they occur, and we 
can't be certain that they don't occur. One series of studies has 
suggested that PB, either alone or in combination with other chemicals, 
may be related to some chronic changes in nerve function reported by 
Gulf War veterans. However, weaknesses in the design of these studies, 
which include uncertainties about exposures and a small sample, made it 
impossible for us to decide if exposure to PB is associated with long-
term nerve damage. We recommend further investigation using an improved 
design.
    The third agent that we considered was depleted uranium. During the 
Gulf War, some tanks and munitions containing depleted uranium caught 
fire or exploded. As a result, a number of soldiers are likely to have 
inhaled or ingested uranium dust, although the intensity of the 
exposure is unknown. Flying fragments containing depleted uranium 
injured others, leaving fragments embedded in tissue.
    In its depleted form, uranium is 40 percent less radioactive than 
in its natural state. Health effects of natural uranium have been 
widely investigated, mostly in occupational settings. While these 
studies have either shown no effect or a small effect as a result of 
uranium exposure, our committee found weaknesses in many of these 
studies. We could not draw conclusions about exposure to uranium and 
death from a number of diseases, including lymphatic or bone cancer, 
nonmalignant respiratory illness, and diseases of the liver and 
gastrointestinal tract.
    But we were able to arrive at more certain conclusions regarding 
kidney disease and lung cancer. We concluded that there is limited 
evidence of no association between kidney disease and exposure to 
uranium. We based this conclusion on several adequate, consistent 
studies that showed good kidney function despite continuous exposure to 
uranium as it dissolved from uranium fragments embedded in body 
tissues. Similarly, at low levels of exposure, we found limited 
evidence of no association with death from lung cancer. At higher 
levels of exposure, though, the evidence did not permit any conclusion 
about the relationship to lung cancer. We recommend follow-up research 
on veterans with embedded fragments of depleted uranium and other long-
term studies.
    Finally, our committee considered the vaccines given to prevent 
anthrax and botulism. More than 150,000 U.S. troops received injections 
of these vaccines to protect them in the event of biological warfare. 
Based on our review of the scientific literature, we concluded that the 
evidence is sufficient to demonstrate an association between these 
vaccines and subsequent short-term local and systemic effects. The 
symptoms include redness and swelling at the site of injection, similar 
to those associated with any vaccination. But when it came to 
evaluating more lasting effects, we didn't find any published, peer-
reviewed studies that systematically followed subjects over the long 
term. This situation is not unusual, as few vaccines have been 
monitored for adverse effects over long periods of time.
    Since troops usually received several vaccines, often within a 
short span of time, some have questioned whether several vaccines in 
combination may have created a cumulative effect when any single 
injection did not cause a reaction. Although we did find some research 
on cumulative effects of vaccines, the shortcomings in these studies 
made it impossible for us to form a strong conclusion. We did decide 
that this evidence was inadequate to determine whether an association 
exists.
    This is a brief overview of the report's findings. The IOM is 
beginning the second phase of this study, and it will examine the 
literature on the health effects of pesticides and solvents. This study 
will be completed in 2002 as there is a large body of literature on 
these compounds. Plans for future IOM studies include completion of the 
remaining agents from those listed in the legislation. Additionally, 
the IOM will conduct updates of the literature as new studies become 
available.
    Thank you for your attention. My colleagues and I will be happy to 
answer your questions.
STATEMENT OF ROBERT W. HALEY, M.D., PROFESSOR OF 
            EPIDEMIOLOGY, UNIVERSITY OF TEXAS 
            SOUTHWESTERN MEDICAL CENTER
    Senator Specter. We now turn to Dr. Robert Haley, professor 
of internal medicine and chief of epidemiology at the 
Department of Internal Medicine at the University of Texas 
Southwestern Medical Center in Dallas. Prior to this position, 
Dr. Haley served for 10 years as an epidemiologist and division 
director for the Centers for Disease Control and Prevention in 
Atlanta, Georgia.
    Welcome, Dr. Haley, and we look forward to your testimony.
    Dr. Haley. Thank you very much, Senator. Let me get 
organized here a second.
    Well, as you know, we began studies back in 1994 with the 
funding assistance and encouragement of Ross Perot, who is 
going to talk later on this program. As you also know, I spent 
10 years at the CDC involved in investigating epidemics and 
employing the technique that Senator Hutchison referred to a 
little bit ago. And I think that is the way that we should have 
been proceeding all along to try to solve this.
    We need to go to small groups, a number of studies going to 
relatively small groups, so that you can do the types of 
detailed studies that can actually show the cause of this 
illness. This was the lesson we learned in toxic shock 
syndrome, Legionnaire's disease, AIDS, all of the major 
mysteries that have been solved. And this technique has been 
underutilized in this problem.
    We took a group of Seabees, a battalion, went into them, 
applied a case definition, separated them into those that met 
our definition of a syndrome and those, the normals, who did 
not meet the syndromes. And now we have done a series of 
studies funded by the Perot Foundation and then a second series 
funded by the Joint Chiefs and the Secretary of Defense 
Officer, where we have tried to ask the question: How do we 
solve what the problem--how do we decide what the disease is?
    The problem with the studies like the Iowa study, the 
British studies, they are doing a lot of exams in the CCEP. 
They are doing a lot of examinations, but they are using the 
wrong test. They are using superficial physical examinations, x 
rays, you know, the usual brain MRIs that do not show anything. 
And so predictably, those studies are going to show that there 
is no physical problem to these veterans.
    What we have done is gone in the other direction. We have 
used the might of our research institution, four Nobel 
laureates on our faculty--it is a very austere group of 
people--who can measure all types of brain abnormalities. And 
we have asked, what tests now could we use that might show a 
physical basis for this injury or illness.
    So let me just quickly show you up here--Mark, why do you 
not bring those over here? And I will just show the Senator, 
and the audience can look later.
    But basically, this was our original study from the Seabees 
unit. This is--Dr. Drue Barrett from CDC mentioned how people 
are using factor analysis. It is a way of determining, is there 
a syndrome present in these veterans. In other words, Senator 
Hutchison, you wanted to know: Is there a syndrome?
    Well, what you do is you measure the symptoms of veterans, 
and then you apply this mathematical technique. And this scale 
here shows you the strength of clustering into syndromes. And 
what you see here is three very strong syndromes in this group 
of veterans that we studied. Now this is a very unusual 
finding. You do not find this often.
    Now the key to our study was, however, we studied a whole 
bunch of other veterans before this and came up with what we 
thought the syndromes were and asked the very symptoms that 
would show this. That was the symptoms of the Gulf war 
syndrome. The Iowa study and the British study asked about 
psychiatric symptoms, about psychiatric diseases that we know 
are common in any population. And so their syndromes are going 
to be psychiatric. We asked syndromes that we thought were the 
Gulf war syndrome. And sure enough, there they are, three very 
strong syndromes.
    Senator Hutchison. Are you going to tell us what they are?
    Dr. Haley. Well, yes, very briefly. It is really not very 
material, except I will just give you a quick--we call them 
syndromes one, two and three. Syndromes one and three are 
fairly mild. These guys are still working. They have cognitive 
problems, a lot of body pain, depression, sleep problems, and 
so forth.
    Syndrome two is the bad one, though. These guys are the 
ones who are not working, who are really incapacitated. These 
people have dizziness problems. And I think one of the veterans 
that you are going to talk to later was one that we modeled 
this after, actually, when we discovered that dizziness is a 
real big problem in this particular group.
    We recently talked to people in some VA hospitals around 
the country, and they said, ``Well, we don't see any of this 
dizziness.'' And I said, ``Well, they don't bring it up. It's 
subtle. You need to ask about it.''
    And as soon as they did, gee whiz, they found a bunch of 
these. And now they have done some brain scans that I am going 
to show you in a minute, and they have found the same thing in 
another place.
    OK. Now let me go to the next one, because I know we do not 
have much time.
    The second question about those syndromes is what might 
have caused them, and are they different, and is there a 
connection to some cause in the war. We did a lot of 
epidemiologic studies with self-reported risk factors, as you 
have talked about already. And we had evidence that certain 
chemicals were highly associated with being in one of these 
syndrome groups, compared to the controls. But we have now a 
piece of evidence that is even more important.
    This is a study of a gene called the PON gene. PON stands 
for paraoxonase, but that is immaterial. And there is a 
variety, a special variety, of this called the PONQ variety of 
this enzyme. Now this enzyme is in everybody's blood. And the 
purpose of this enzyme--I do not know why God put it there, but 
it protects you from nerve gas. And that is about its only 
function in the toxicological realm. Now it is also important 
in protecting you from heart attacks and so forth, but that is 
irrelevant.
    The point is, it has a very specific effect in detoxifying 
low levels of nerve gas, when it gets in your blood. So we 
reasoned, OK, if nerve gas is the cause, you would expect the 
sick people to have been born with low levels of that, not to 
have any protection, and the well guys would have had high 
levels of that. So when whatever low level sarin came over, the 
people with high blood levels would be protected. And the ones 
that were born without much of that, it would get through their 
blood and into their brain, and they would get sick.
    Well, in fact, that is exactly what we found. Here are the 
controls in the first column. You see the controls. And their 
blood levels are up between 75 and 150, as you see. And that is 
the normal range in most general population. Look at syndrome 
two. Remember? Those are the ones I said had the most brain 
damage, the most severe problem. And look. Their levels are 
extremely low with three exceptions. And, of course, in 
biology, nothing is ever perfect.
    But the point is, this has shifted way down. This suggests 
these people were born with low levels of protection against 
nerve gas.
    Now remember, this enzyme does not protect you against 
anything else. So the question--so this is very provocative, 
Let me say provocative, evidence. This study is too small yet 
to reach a final conclusion, but it is very provocative 
evidence that not only shows why some guys got sick and others 
did not, it also connects it to nerve gas, because this enzyme 
does not do anything else in terms of chemicals.
    OK. The next finding. Now the next real issue--Mark, hold 
those, and let me hold this up--OK, is this brain damage? Now 
everybody says, well, this is just a syndrome. It is just 
symptoms. Symptoms are increased in one group over another. 
Well, no, it is not. We think there is a brain cause for this.
    Now, in order to look at this, we first did a lot of exams, 
a lot of physical exams, by neurologists in X-rays and lab work 
and compared the sick people and the well people. All right? 
None of that was any different. You see, that is what the Iowa 
study is going to show. It is going to show there is no 
difference, because they are only doing those things.
    We then said, well, let us go one step further. Let us do 
brain MRIs, brain scans of the head. Well, we did those. And 
here is a typical brain scan. And those were all normal, all 
the same in both groups, no difference. So there is no tumor or 
stroke or multiple sclerosis or anything like that, 
Alzheimer's, or anything that would explain the difference in 
symptoms.
    So then we went to one further level. There is a new kind 
of scanner called magnetic resonance spectroscopy, or MRS for 
shot. Instead of MRI, this new one is MRS. All right? Now what 
you do there, you have to focus on one part of the brain. And 
what I am showing you, here is the big part of the brain here. 
And this is the little brain stem down here that connects down 
to your spinal cord. All right? We focused on where this little 
box shows right here. We focused the MR machine on that little 
box. And with this new MRS technique, you can measure the 
chemical concentrations of all the chemicals that are right 
here. This is MRS.
    This is a printout that shows you what the chemicals are in 
typical brain tissue. And there are three main chemicals. And I 
will focus on this one. See this big spike here? This is called 
NAA. It means N-acetyl aspartate. But it is one of the main 
chemicals in your brain, and it is found only in nerve cells, 
neurons, nerve cells, and the connections between nerve cells, 
the hardware in your brain.
    Now, this chemical is really interesting. It is like a 
barometer of health of the neuron, of the brain cell. And 
anything that damages that neuron and makes it unable to 
function causes this chemical to go down. It drains out. Now 
nobody knows why or whatever, but the point is, it is a very 
sensitive and well-documented--there are at least 300 papers 
written in scientific literature showing this is a good 
measure. They have used it in multiple sclerosis, in 
Alzheimer's, and 100 different brain diseases to show that this 
is a measure of the health of those brain cells. And anything 
that damages brain cells causes this to go down.
    So we then compared a group of normal veterans and a group 
of sick veterans with our Gulf war syndrome two, you know, the 
one that is really bad. Well, these guys are really sick, where 
they had the genetic predisposition that suggests they were 
exposed to sarin nerve gas and had brain damage as a result. 
Look what we see. In the group of controls, we have a normal 
level of this chemical, meaning their brain cells are normal in 
this part of the brain now. Whereas in the sick veterans with 
syndrome two, look at that. Look at the difference.
    The level of NAA is substantially reduced from 10 to 25 
percent.
    Senator Hutchison. And that is the only thing that is 
different.
    Dr. Haley. That is the only thing that is different.
    Senator Specter. Dr. Haley, how much longer do you expect 
to be?
    Dr. Haley. About 2 minutes.
    OK. This is very strong evidence, at least in this small 
group of people, that there is a brain injury, and it is in the 
brain stem and the surrounding areas, called the basal ganglia, 
these deep brain structures. It turns out, when you look at the 
literature on diseases that affect these structures, the 
symptoms are Gulf war syndrome. It is exactly the kinds of 
symptoms you would expect.
    Now one final finding. We just published this in the last 2 
weeks. So not many people know about this yet. This was in the 
Archives of Neurology 2 weeks ago.
    We now looked at this measure of brain cell injury down 
here, the same one I just showed you. So in other words, up 
here they are normal, normal brains are up in here. And the 
ones with brain injury are down here. OK? We measured here the 
amount of dopamine, the brain neurotransmitter that these 
people's brains are producing.
    And there is a blood test, a way you can test in the blood 
for the breakdown products. But the idea is, how much dopamine 
is their brain producing?
    You remember just 2 days ago, the Nobel prize for this year 
was awarded to the people who discovered the idea of dopamine. 
It is one of the key neurotransmitters of the brain.
    We found that the more brain damage you had, the more 
evidence of abnormal neurons in the basal ganglia--that is, 
these deep brain structures--the higher your brain dopamine 
production goes. In other words, if the brain dopamine 
production is going out of control, this is exactly what you 
find when you experimentally injure these deep brain structures 
in, say, rats or other experimental animals. What happens, the 
first thing that happens, is dopamine goes out of control. And 
then over many, many, many years these cells, being overworked, 
they wear themselves out, and then you get low dopamine, and 
you may get things such as Parkinson's disease or other 
diseases that relate to this area of the brain.
    Now the probability, even though this was a fairly small 
sample, the probability that this result occurred by chance 
because the sample is too small is this, 1 in 100,000. This is 
a very, very strong finding. Now again, this is a small sample, 
and, you know, we have to replicate it.
    Now, in final let me just say, we took a very unique and 
new approach. It is really based on the old CDC technique, 
cases versus controls. And then you do the tests that are 
necessary to show what the disease is. Remember in 
Legionnaire's it took them a year to find all the different 
tests and to find the one that really paid off. Well, we think 
we have done that.
    Now the next step is, we have proposed a large grant 
proposal to replicate this, to take a random sample of those 
who served in the Gulf war and a random sample of those who did 
not, do, Senator Specter, a telephone survey, as you were 
talking about a minute ago, a telephone survey to determine how 
many have these syndromes and how many do not, and then bring 
in small random samples of those and try to replicate this.

                           PREPARED STATEMENT

    In other words, this is not a definitive finding yet, but 
it is a major lead that needs to be followed up. We proposed a 
grant of $25 million, because the survey is expensive. We then 
want to follow these people up and do much more intense brain 
chemistry. We also want to do animal studies in comparison to 
study them in parallel. This is very expensive research over 
several years. That proposal is at Fort Detrick now. We 
actually submitted it as an unsolicited contract proposal, and 
we hope that we will get support.
    Thank you.
    Senator Specter. Thank you very much, Dr. Haley.
    [The statement follows:]
                 Prepared Statement of Robert W. Haley
    Senators--I want to thank you for the opportunity to speak to you 
about the research on the nature and causes of Gulf War syndrome, 
conducted and coordinated by my group at the University of Texas 
Southwestern Medical Center in Dallas. Our research began in 1994 under 
initial funding support from the Perot Foundation of Dallas and has 
been continued under a 1997 cooperative agreement with the Office of 
the Secretary of Defense administered through Ft. Detrick, which 
expired two weeks ago. In July we submitted a proposal for funding a 
new phase of our research.

                            INITIAL FINDINGS
    Our initial studies focused on 249 members of a Reserve Naval 
Mobile Construction Battalion, or Seabees. In that work, we made four 
important observations. First, we found that there is a single Gulf War 
illness with three variants. Second, those with the illness have more 
abnormal brain function by objective tests than well veterans, 
suggesting a brain injury or illness. Third, the sick veterans were 4 
to 32 times more likely to report exposure to combinations of certain 
chemicals in the war, specifically sarin nerve gas, side effects from 
pyridostigmine, highly concentrated government-issue DEET insect 
repellant, and pesticides in flea collars. And fourth, in collaboration 
with researchers at Duke and Kansas State universities and the EPA, we 
experimentally produced brain and nerve damage in hens with 
combinations of some of these same chemicals, not previously thought to 
be neurotoxic. In January 1997 this work passed rigorous peer review 
and was published in three scientific papers, appearing back to back in 
the Journal of the American Medical Association. A research group in 
India led by K. Husain, has extended these findings by demonstrating 
neurological damage from low-level sarin nerve agent in two animal 
species.

                          MOST RECENT FINDINGS
    Later in 1997 we submitted a $16 million proposal to extend and 
replicate our initial findings in a national survey, but it was not 
funded by the government peer review system administered by the Persian 
Gulf Veterans Coordinating Board. Later the Joint Chiefs and the 
Secretary of Defense conducted a special peer review of the proposal 
and granted us partial funding of $3 million through a cooperative 
agreement to begin further testing and plan a national random-sample 
survey to replicate our findings.
    With that funding, we have made four additional important 
observations. First, we identified a gene, the PON1 gene, that appears 
to have predisposed soldiers to getting the Gulf War syndrome and 
appears to link the illness with low-level sarin nerve gas exposure. 
Second, we demonstrated the site of brain damage with a new brain 
scanning test called Magnetic Resonance Spectroscopy (MRS). Third, we 
found abnormal increases in the brain hormone dopamine in those 
veterans with the worst brain damage measured by the MRS scans. (The 
original brain dopamine research was awarded the Nobel Prize earlier 
this week.) These findings were all published in top medical journals 
after passing rigorous peer review. Our fourth finding has been to 
develop an animal model of the Gulf War syndrome, that is, long-term 
behavioral disturbances from administration of low, sub-symptomatic 
doses of the chemicals to which Gulf War veterans were exposed. This 
has not yet been published.
    Along the way, I published important commentaries in peer-reviewed 
journals showing that the government studies pointing to stress as the 
cause of Gulf War syndrome were based on statistical errors that 
invalidated them.

                      LIMITATIONS OF THE RESEARCH
    To put our research findings into proper perspective, it is 
important to realize that we have framed a theory or hypothesis which 
could explain the nature and causes of the Gulf War syndrome, but this 
theory is not thoroughly proven. Since our studies were the first to 
blaze this trail, they were relatively small and focused in a single 
battalion and therefore might not be representative of what is true in 
the larger Gulf War veterans population. On the other hand, the CDC 
studies that have solved hundreds of epidemic mystery diseases in the 
past have traditionally been very similar to our studies on Gulf War 
syndrome. Epidemic diseases have unique characteristics that make these 
studies useful.
    Consequently, our theory is in need of extension by us and 
replication by other researchers working independently but using the 
same methods as we have used in deriving the theory. At present we have 
replicated parts of our work in a new group of Gulf War veterans 
recruited through the Dallas VA Medical Center, and an independent 
researcher in another state has replicated our MRS brain scanning 
finding in a small group of sick and well Gulf War veterans. Several 
other studies have questioned our theory, but none has actually tested 
our findings using the same methods. Scientifically, a replication 
requires use of the same methods.

                       CURRENT RESEARCH PROPOSAL
    Last summer my research team submitted a new proposal to extend and 
replicate our work. We asked for $25 million over two years to 
establish an independent Gulf War Illness Research Center to do the 
studies necessary to advance the findings substantially. Briefly, we 
proposed to:
    1. Perform a national survey in random samples of Gulf War-era 
deployed and non-deployed veterans to compare the prevalence of the 
illness we have identified. DOD has already invested $500,000 in 
planning this survey, and it is virtually ready to go. An independent 
survey firm will carry out the survey to ensure objectivity.
    2. Upgrade to the latest brain imaging technology to explore deeper 
into the nature of the brain damage and attempt to develop a cost-
effective diagnostic test that could be widely applied to make 
objective diagnoses.
    3. Extend our new laboratory animal model of Gulf War syndrome by 
testing for chronic behavioral effects of low-level sarin alone and in 
combination with pesticides and pyridostigmine.
    4. Re-study veterans from our prior studies to determine whether 
they are getting better or worse over time.
    5. Identify and test promising treatments.
    For this new work to be successful, it will be important to receive 
funding under a mechanism that will give us an appropriate degree of 
independence to follow our own instincts on research directions in a 
timely manner. In addition, we will need the cooperation of the 
Department of Defense in providing the computer list of Gulf War-era 
military personnel for us to draw our national random sample, assisting 
us in promoting the survey to maximize the participation rate, and 
providing exclusive chemical reagents for our laboratory experiments.
    This research was submitted as an unsolicited contract proposal to 
Ft. Detrick's contracting department in July, and we are awaiting a 
reply.
STATEMENT OF HON. MAX CLELAND, U.S. SENATOR FROM 
            GEORGIA
    Senator Specter. We have been joined by our distinguished 
colleague from Georgia, Senator Max Cleland. Senator Cleland is 
here to make an introduction. And as our custom is, when a 
colleague enters the room, we defer to him. We do interrupt a 
witness, but we defer to our colleague as soon as there is a 
break in the action.
    So we welcome you here, Senator Cleland. We understand you 
are going to introduce Mr. Ross Perot. We are not sure that Mr. 
Perot needs an introduction, but that is not the standard for 
introductions in the Senate.
    But just a word or two about you, Max. You have an 
extraordinary record. It has been our pleasure to have you in 
the Senate since your election in 1996 and a very distinguished 
veteran. I was very impressed when at lunch one day you told me 
what life day was.
    Life day is the day when you live, notwithstanding being 
victimized by a shrap line explosion where you suffered very 
severe injuries, as are apparent, and then went to become a 
State senator and Secretary of State and head of the Veterans 
Administration and now a U.S. Senator.
    We are proud to serve with you, Senator Cleland, and the 
floor is yours.
    Senator Cleland. Thank you very much, Mr. Chairman. It is 
in my capacity as a former veteran and certainly as a former 
head of the Veterans Administration and my continuing interest 
in the lives and well-being of our veterans that I gladly 
appear today. It has been my pleasure to get to know Dr. Haley 
and his magnificent pioneering research. We have discussed this 
matter over the last 2 or 3 years. And it is a magnificent 
story, an investigative story, worthy of Sherlock Holmes at his 
best. And these deductions bring a profound insight, I think, 
into the question of the Gulf war syndrome.
    But one of the men, if not the man, behind getting this 
research under way is the person I am about to introduce today. 
He is a man who is deeply dedicated to our country. He is 
deeply dedicated to our veterans and the families who suffer 
from war and from military service.
    Ross Perot has a long history of coming to the aid of our 
country's servicemen and women. In 1972, he received the Medal 
for Distinguished Public Service for his 4-year project to 
improve treatment of our Vietnam prisoners of war. I can think 
of no citizen who has done more for our service men and women.
    Almost 700,000 active duty service members and activated 
National Guard and Reserve members served in the Gulf theater 
of operations. And after hearing stories of soldiers who 
returned from the Persian Gulf war sick or disabled for unknown 
reasons, Ross Perot approached the University of Texas 
Southwestern Medical Center in Dallas to personally fund a U.S. 
Armed Forces veterans distinguished Chair for medical research.
    Ross is the power and the driving force behind this 
research that Dr. Haley has brought to us. He is helping 
researchers to investigate Gulf war illnesses and search for 
ways to prevent and treat it. He has helped combine the private 
sector with researchers at the Departments of Defense and 
Veterans Affairs to enhance efforts to help those who served 
our country so heroically.
    It is my honor to introduce a great patriot, a great 
American, and a man who is deeply committed to finding the 
answers to Gulf war syndrome, Mr. Ross Perot.
    Senator Hutchison. Mr. Chairman, as Mr. Perot is coming 
forward, I would just like to say that I cannot think of anyone 
who could better take my prerogative away and introduce one of 
my constituents than Senator Cleland.
    And I am proud that he did. Thank you.
STATEMENT OF ROSS PEROT, PRESIDENT, CEO AND CHAIRMAN, 
            PEROT SYSTEMS CORP.
    Senator Specter. Well, welcome, Mr. Perot. We know of 
your--go on.
    Mr. Perot. I have two things that I would like all of you 
to look at. I would like you to look at this picture of a young 
tiger going into combat in Desert Storm. That is a book. He is 
dying there. He is dying of Desert Storm syndrome. I would like 
you to look at him now, sitting in his wheelchair with his 
little children around him in the last few months he had. That 
is what this is all about.
    Senator Specter. Well, thank you very much for the book and 
the magazine, Mr. Perot. And we----
    Mr. Perot. I just--you see a picture is worth a thousand 
words. And when you think of what----
    Senator Specter. We are not going to charge any of that 
against your time. Subtract 2,000 words from your testimony.
    Mr. Perot. There is one other good example here today, the 
young man who works with Senator Cleland. Remember the story of 
the enlisted man whose legs got entangled in a mooring line on 
a ship? He was being dragged to a point where his legs had been 
literally torn off. And this ensign raced in to rescue him, 
freed him up, and then his leg got tied up, and he lost his 
leg.
    This is Ensign Johnson. He must--he was here a minute ago. 
I hope he is here now. Now this is a man who did the right 
thing. And when you see Senator Cleland, I am sure if you ask 
him, if you say: Well, as soon as you were wounded, did someone 
come out and get you? He could tell you stories that would make 
you cry, in terms of risks that people took to rescue him.
    That is what we are talking about here today, is rescuing 
people that have suffered for 9, 10 years, and defining what 
the injury is and clearing it up. I have had the privilege for 
many years for assisting military personnel and their families 
with health problems that could not be taken care of within the 
military health system. I got started in this when a group of 
seriously injured Desert Storm veterans contacted me in 1994 
seeking medical assistance. They had been exposed to chemical 
agents and other toxic chemicals during the war.
    These people had a wide range of serious health problems, 
including children that had been born with crippling 
deformities. Can you--I would much rather lose my leg than have 
a child born without one. And I know all of you would agree 
with that. That is a real price to pay for your country.
    Logically, you would ask, where did Iraq get these chemical 
weapons. We gave them to them in the 1980s to use against Iran. 
That was a violation of the rules of warfare. We did it. That 
is history. In plain talk, we violated the first rule of war, 
and that is do not shoot yourself. That is maybe one of the 
reasons we, you know, juggle, tap dance, and chew gum instead 
of working on this problem.
    Studies indicate that up to 100,000 people who fought in 
Desert Storm have these health problems, including brain damage 
from chemical agents, which we refer to as Gulf war syndrome. 
We must solve these problems for two reasons. One, to treat our 
wounded soldiers and their families, and to protect our 
military forces and our entire population from these chemical 
agents in future wars.
    Other nations have been working on how to protect their 
populations since the 1950s. Russia had all this work done in 
Czechoslovakia. The Russians brought people who were captured 
in the wars of Vietnam and Korea, our men, all the way in, and 
they were used as human guinea pigs to determine how you test 
your people against chemical weapons and nuclear radiation.
    If you question that, there was a Dr. Jan, J-a-n, Sejna, S-
e-j-n-a, who worked in the--he was a defector from 
Czechoslovakia, came out in about 1968. He worked in the 
Pentagon in the Defense Intelligence Agency. So he must have 
some credibility. I have heard him speak openly in meetings 
about the fact that our men were used as laboratory animals.
    The interesting phenomena is--let us fast-forward to this 
war--guess who we used at the frontiers of technology to 
protect our people from chemical weapons, the Czechoslovakian 
group. They have written a book about it. I am having it 
translated into English now. And now you see all the pieces of 
the puzzle coming together. We did not prepare to protect our 
men, and we had to rely on the Russia technology done in 
Czechoslovakia to have that done during the war.
    Modern technologies, including nuclear, chemical and 
bacteriological weapons can totally change the nature of future 
wars. We could have our entire population--this is how 
important this meeting is. We could have our entire population 
devastated in a non-declared war waged in the United States, 
and we will not even be able to identify the enemy. I am sure 
you will recall the use of chemical agents in the Tokyo subway, 
as one little example.
    You know we have nuclear weapons with the destructive power 
of the weapon we dropped on Hiroshima that you can put in a 
suitcase. Think creatively about how that could be used. We 
have no effective defense against these chemical weapons and no 
effective way to protect our troops against these chemical 
weapons. These are compelling reasons to move forward 
aggressively to find answers.
    Our Government has spent $500 million trying to prove that 
these illnesses were created by stress. And they have failed. 
This conclusion is--now, look, you went over, you fought, you 
were wounded, you came home, you cannot do the things you used 
to do. And I have talked to so many of these people, it would 
break your heart when you talk to them. And you have some here 
today.
    They served us. We have not served them. And then to have 
all of this just written off saying, well, he could not handle 
the stress. It makes no sense at all, when you look at the 
numbers from prior wars. Do not think for a minute that the 
military units in the Pentagon are doing this. The military 
units in the Pentagon care for these people. And if somebody in 
this audience is wondering how to get me to go away, if the 
Chairman of the Joint Chiefs and all the service chiefs called 
me and said: Perot, we do not want you do this, you are doing 
the wrong thing, our men have stress, they are not wounded in 
combat, I will stop.
    Well, let us assume the stress theory has validity. Well, 
we should have had terrible stress in World War II. It was a 
really long, hard, dirty war, fighting day after day, month 
after month after month. We have twice the incidents of stress 
using the definition that this group has come up with in the 
100-hour almost non-war that we had in World War II. To me that 
indicates right away. Three times the incidence of stress that 
we had in Korea. We had battles in Korea.
    You remember when the Marines were fighting the Chinese? 
There were so many of them, and some of them did not even have 
weapons. But there were just so many of them, they could not 
fire fast enough to keep from being overwhelmed. That is a 
stressful situation. And yet we have three times the stress in 
Desert Storm that we had there.
    Now then, after Vietnam we did have a post-Vietnam stress 
syndrome. I think if we had ever done any real research on it, 
we would find that most of that came from rude treatment 
received by men when they came home. When you come home and get 
spat on on the streets, that is worse than getting shot at.
    Now interestingly enough, we had no post-Vietnam stress 
syndrome from prisoners of war, who normally are treated as 
unlucky people when they come home. But in that war, they were 
treated as heroes. Our men coming home from the short war in 
Desert Storm were treated as heroes. There were parades all 
over the place. They got the warm welcome home, but they had 
been poisoned by chemical agents. And we have an obligation to 
treat them.
    This is agent orange revisited. I lost several friends to 
agent orange. So I have spent a lot of time studying it. It was 
a serious problem in Vietnam that has resulted in many deaths 
over a long period of time. Now keep in mind, just because you 
die 25 years later from something you got on the battlefield, 
it is still as relevant as if you get hit in the head with a 
bullet. And just because it is subtle, let us not duck it and 
bob and play little games here.
    Our Vietnam veterans are still dying. For example, as I was 
writing this speech yesterday, I got an emergency call from a 
former marine in Houston, Texas, that is dying from agent 
orange that cannot get any kind of reasonable help through the 
Veterans Administration. With his own money, he went to M.D. 
Anderson Hospital, which is one of the best places in the world 
to go. Then he tried to get help from them. You see the flaws 
in the system?
    OK. So the worst thing that we can do to these men, if you 
want to hit them in the face, is call what they have stress. I 
have worked with the U.T. Southwestern School since the mid-
1980s, funding their research. Southwestern is one of the most 
respected medical institutions in the United States.
    It has four Nobel prize recipients actively working in 
research today, more than any other medical school in the 
world, part of it involved with Desert Storm syndrome. I have 
worked for over 10 years with Drs. Brown and Goldstein, who 
were two Nobel prize recipients, whose research on findings in 
cholesterol have had a worldwide impact on controlling heart 
disease.
    Now again, I want you to know this about Southwestern. I 
have called them again and again and again since the mid-
eighties. Panama. Let us just take all of them that we have 
been through. Haiti. Every single situation, we had people with 
serious problems. A who's who of the military would call me and 
say: You have to take care--I love this. Generals and admirals 
calling you concerned about their privates.
    Now if we had that sort of--and their seamen. It just--it 
goes on and on. But they would call. Southwestern would step 
in. The top people would look at the people. Again and again 
they would treat them successfully, and in many cases never 
even send a bill to anybody for it. It was their way of saying 
thank you for your service.
    That is the reason I asked Southwestern to put together a 
team. They selected Dr. Haley. You have heard his background. I 
will not go through that again. He spent months analyzing this. 
He started out in a very skeptical way, like a good detective, 
and just gathered the facts. And you have heard his conclusions 
here today.
    One thing I want to make very clear. You start with small 
studies, and then you come up with what looks like might be a 
good, solid idea. And then you spend all your money. And that 
is the approach he has used. And that is the approach that has 
been successful again and again and again.
    Senator Specter. Mr. Perot, how much longer would you take 
for your testimony?
    Mr. Perot. I will stop right quick and just say that our 
challenge--we have had a 10-year delay. It is caused by a group 
that has branded this stress and wants to keep it stress, no 
matter what. And I think the only way to get this program 
moving is to come up with a new plan, where they work either 
for the National Institute of Health or the Center for Disease 
Control.
    And certainly they cannot be reporting into this group, 
because it is a non-responsive group. Sometimes we have waited 
up to 18 months to get the things we need. And if you are 
working on some of these things, you need a quick response and 
keep moving.
    We also have had--and I do not think anybody has mentioned 
this. Only in America would we waste taxpayer money on a 150--
let me see. I think it is $150 million that they have spent so 
far on public relations trying to sell the stress idea, and at 
one time had even hired a guy that was a lobbyist for the 
tobacco industry. There is no more negative thing I think you 
could do, in terms of offending a person who was wounded by 
this.
    Now let me close my comments now and take your questions. 
Sorry if I overran.
    Senator Specter. Well, thank you very much, Mr. Perot. We 
thank you for your leadership on the issue. And the frustration 
which you expressed Senator Hutchison had commented on, and I 
had, too, after our first panel.
STATEMENT OF CAPTAIN JULIA DYCKMAN, U.S. NAVY RESERVE 
            (RETIRED)
    Senator Specter. We have one more witness before we are 
going to turn to questions. And that is Captain Julia Dyckman, 
who served in the Persian Gulf war at Combat Fleet Hospital 15. 
Commander Dyckman was on active duty in the Persian Gulf for 5 
months and suffers from Gulf war syndrome.
    You were a commander at the time, a captain now. We welcome 
you here, Captain Dyckman, and look forward to your testimony.
    Captain Dyckman. You have to bear with me, because I do 
have Gulf war illness. So I have a lot of the results of the 
damage that the rest of the vets have.
    I would like to graciously thank the subcommittee for 
allowing me to testify regarding the appropriation of funds for 
research and treatment of Persian Gulf illness. At the time of 
the Persian Gulf, I was a commander with Naval Reserve Fleet 
Hospital 15. And it was a 500-bed hospital, and it was 
assembled at the site west of Al Jabar, Saudi Arabia.
    When I came back, I have 21 medical diagnoses given to me 
by the Navy as a result of my Persian Gulf experience. I am on 
what they call TDRL, which is a temporary disabled retired 
list, which gives me 90-percent disability from the military 
and 100 percent from VA, because I am unemployable. As for 
these 21 diagnoses, you can find them in my written statement, 
which I will be providing.
    Now you have to remember I had a complete military physical 
when mobilized and was in excellent health before leaving the 
United States. However, after 9\1/2\ years what is important is 
not these particular diagnoses, but the unique findings in 
myself and other veterans who have received advanced diagnostic 
procedures.
    The advanced tests have shown that we have 
hypercoagulability, nerve damage, abnormal PETs and MRSs now, 
decreased circulation throughout the whole body, degenerative 
bone disease, mitochondrial changes in muscle tissues, abnormal 
immune lab results, and an increased number of various 
autoimmune diseases.
    Laboratory tests and biopsies have shown organisms such as 
microplasm cytomegalovirus, abnormal levels of antibodies to a 
chemical compound called squalene, herpes six viruses, and now 
newly discovered stealth virus, and even a fraction of the HIV 
envelope. Discovery of these results required very specific 
tests, but DOD, VA or NIH did not provide these tests.
    In my personal experience, I have dealt with DOD, VA and 
the National Institute of Health. I do want to say one other 
thing, though. Another problem I found is that an organization 
cannot investigate itself, if that organization possibly caused 
the problem in the first place. In other words, the fox should 
not watch the henhouse.
    Now, I am willing to give some examples of the problems I 
have had with these organizations and their protocols. And you 
can read some of the other ones in my written testimony.
    First of all, DOD. Its major failing is that it acts as if 
it thinks it is guilty of something and thus becomes defensive. 
It seems to predetermine the results at once, and so spends 
millions proving that any abnormality or the cause either does 
not exist or is not the responsibility or the result of DOD 
action.
    DOD did have a proper protocol via the Comprehensive 
Clinical Evaluation Program to actually determine the causes of 
Persian Gulf illness. However, for whatever reason, they did 
not follow their own protocol. And hence, the CCEP program 
became useless.
    Now here are some examples that I have encountered. In 
September of 1997, Mr. Rostker signed a letter, which was sent 
to me, regarding events in and around the Al Jabar area. I was 
with the Seabees that Dr. Haley is talking about. The Seabees 
stationed there had parts of their t-shirts and combat boots 
turn purple and also sought medical treatment after being 
exposed to airborne unidentified noxious fumes.
    DOD's assessment was that these personnel were definitely 
not exposed to chemical warfare agents. Lab findings said that 
the change could be a result of bi-products of industrial area 
operations, such as a fertilizer plant, which was located 
nearby. OK. It was not a chemical warfare agent, but it was 
chemicals. Anyone who lived near Bhopal, India, knows what a 
chemical will do.
    The DOD has also spent many years and several million 
dollars proving that the soldiers and the marines that had 
chemical burns, well, they simply did not. I find it 
interesting that they can go back almost 10 years and determine 
by reading valid medical records written by on-the-scene 
examining physicians that the doctors were simply mistaken.
    In 1996, a research team found that higher-than-normal 
levels of squalene were present in Gulf war veterans and that 
the source of this squalene was probably immunization. The DOD 
said wrong. However, just recently, DOD stated that there are 
low naturally occurring levels of squalene in the anthrax 
vaccine. DOD's credibility is shot.
    VA. The VA is controlled by cost. They have a fixed budget. 
And this seems to result in a priority to minimize disability 
compensation by proving that you do not have a service-
connected disability. They cannot afford to do proper research 
or even allow expensive or unique tests. Medical care and lab 
results are unpredictable and unreliable. They do not have the 
specialists necessary for proper care. And it seems when they 
get someone who is that specialist, they are let go, except in 
psychiatry.
    Now, an example: I participated in a VA study at the 
University of Pennsylvania. And they were doing whole body PETs 
and a xion study to assess muscle blood flow in the legs. The 
results showed that I had decreased blood flow to certain areas 
of my body and inflammatory muscle disease. However, their 
funding was not renewed, and the physicians were discharged.
    The VA did get funding to perform this blind study 
involving microplasm and doxycycline. I applied to be in the 
study. I did test positive for microplasm, but I had taken 
doxycycline a number of years ago, and they said I was 
ineligible to participate in the study.
    As for the study on exercise, the study was limited to the 
Philadelphia area. And so to participate in this study, I would 
have to drive 2 hours to Philadelphia, exercise, and drive 2 
hours home. I have inflammatory muscle disease and chronic 
fatigue. This would have been impossible for me and other 
veterans with Persian Gulf illness.
    Senator Specter. Captain Dyckman, how much longer will your 
testimony be?
    Captain Dyckman. Quite a bit longer, if that is at all 
possible.
    Senator Specter. Well, could you summarize it for us, 
please?
    Captain Dyckman. OK. I will skip then some of the other 
examples. But NIH, I had problems with their recording of the 
results. And they ended up being tied into Bethesda Naval 
Hospital. When the results did not meet their criteria, they 
never sent another veteran over to this particular study.
    Here is my recommendations. It will take me 2 minutes.
    Remove DOD and VA as designers of the research. They are 
valuable for their input, and they can provide goal setting. 
And they need to be involved by following the research and 
suggested protocols, plus providing referrals of their veterans 
to appropriate researchers.
    Some of the doctors that I have dealt with that have 
produced some of the abnormal results, and they have also given 
me some relief. Dr. Pam Asa discovered squalene in my blood 
several years ago. Research needs to find out where the 
squalene came from.
    Dr. Bronswager in the area of neurological effects and 
treatment has been effective in developing preventive measures 
to reduce flare-ups of the illness. Dr. John Martin of the 
Center for Complex Infectious Diseases has detected stealth 
virus in my tissues through blood work and biopsies. His 
research has possibility in linking viral and bacteriological 
organisms to the cause of Persian Gulf illness.
    Dr. David Berg of Hemex Corporation has developed a 
valuable test to prove the hypercoagulability of some veterans. 
His results are being published this month. Dr. Kathleen 
Hannen, along with Dr. Berg, have developed a protocol for 
treatment for hypercoagulability in Persian Gulf illness. I am 
presently undergoing treatment using heparin, as well as the 
transfer factor in this new protocol.
    One last area in funding for treatment and testing, the 
average Persian Gulf veteran and his family cannot obtain 
either the testing or treatment for their various illness. 
Since the illness is not named, most insurance companies and/or 
Medicare will not cover their testing and treatment. The 
illness must be named now.

                           PREPARED STATEMENT

    Persian Gulf illness is called an undiagnosed illness. No 
one pays for testing or treatment of an illness that might not 
be there. After battling for years, I am better off now than 
when I started in 1991. This is mainly due to interest and 
kindness of private researchers, often unfunded. I feel like my 
government has left me out in the cold after many years of 
service.
    [The statement follows:]
                 Prepared Statement of Julia Y. Dyckman
    I would like to graciously thank the Subcommittee for allowing me 
to testify regarding the appropriation of funds for research and 
treatment of Persian Gulf Illness.
    My name is Julia Dyckman and I am a Persian Gulf and Vietnam 
veteran. Currently I am a Captain, USNR on TDRL. TDRL means I am on the 
Temporary Disabled Retired List from the US Navy with a 90 percent 
disability rating. The VA considers me 100 percent disabled 
unemployable. I am an unemployed registered nurse, Pediatric Nurse 
Practitioner, and have a MPH from the University of Hawaii School of 
Public Health.
    I would like to describe my experiences as a Persian Gulf vet who 
became ill while in the Persian Gulf and has been trying to get help 
for the last 9\1/2\ years. Throughout these years, I had to deal with 
the Department of Defense (DOD), Veterans Administration (VA) and other 
organizations, becoming a participant in some research programs as well 
as a few treatments protocols.
    At the time of the Persian Gulf war, I was a Commander in the Naval 
Reserve who was activated January 16, 1991 to serve at Combat Zone 
Fleet Hospital 15. Fleet Hospital 15 was a 500-bed hospital. It was 
assembled at a site west of Al Jubayl, Saudi Arabia.
    I have received a total of 21 medical diagnoses from the Navy as a 
result of my Persian Gulf experience, they are:
  --Diffusely increased sympathetic nerve traffic with increased 
        sympathoneuronal outflows due to autonomic nervous system 
        dysfunction
  --Hypertension secondary to the above
  --Resting tachycardia
  --Hepatitic steatosis and bile stasis
  --Chronic cholecystitis
  --Right upper quadrant intra-abdominal adhesions
  --Reflus esophagitis
  --Chronic gastritis/duodenitis
  --Irritable bowel syndrome
  --Chronic diverticulosis
  --Chronic abdominal pain due to above diagnoses
  --Menometrorrhagia
  --Polyclonal gammopathy of unknown significance
  --Cephalgia
  --Abnormal brain magnetic resonance imaging
  --Cognitive dysfunction
  --Fibromyalgia
  --Symptom complex compatible with chronic fatigue syndrome
  --Plantar fasciitis
  --Perifollicular dermatitis
  --Post-traumatic stress disorder
    Remember that I had a complete military physical when mobilized and 
was in excellent health before leaving the United States.
    However, after 9\1/2\ years, what is important is not these 
particular diagnoses but the unique findings in myself and other 
veterans who have received advanced diagnostic procedures. The advanced 
tests have shown that we have:
  --hypercoagulability
  --nerve damage
  --abnormal PETS and MRS's
  --decreased circulation throughout the whole body
  --degenerative bone disease
  --mitochondrial changes in muscle tissue
  --abnormal immune lab results
  --increased numbers of various autoimmune diseases.
    Laboratory tests and biopsy results have shown organisms such as:
  --mycoplasm
  --cytomegalovirus
  --abnormal levels of antibodies to a chemical compound called 
        squalene
  --herpes VI virus
  --newly discovered stealth viruses
  --fractions of the HIV envelope
    Discovery of these results required very specific tests but DOD, 
the VA, or NIH does not routinely run these tests.
    This combination of unique abnormal findings is important in 
determining the cause of the Persian Gulf Illness. Finding the cause is 
necessary so that funding and research can be directed to the 
organizations that have the attitude, desire, and strategy to find a 
cure or at least a treatment that leads to a better quality of life. An 
organization cannot investigate itself if that organization possibly 
caused the problem in the first place. In other words, the fox should 
not be watching the hen house.
    In my personal experiences I have dealt with the DOD, the VA, and 
the National Institutes of Health (NIH). These were the only 
organizations available to me after my return from the Persian Gulf. 
Frankly, I do not understand their working inter-relationships and 
their inability to be objective when it comes to Persian Gulf Illness.
    Department of Defense.--Its major failing is that it acts as if it 
thinks it is guilty of something and thus becomes defensive. It seems 
to predetermine the results it wants and so spends millions proving 
that any abnormality or the cause either doesn't exist or is not the 
responsibility or the result of DOD action. DOD did have the proper 
protocol, via the Comprehensive Clinical Evaluation Program (CCEP), to 
actually determine the causes of Persian Gulf illness. However, for 
whatever reason they did NOT follow their own protocol and hence the 
CCEP became useless. Examples of DOD problems are:
    In 1997, Mr. Rostker signed a letter regarding events in and around 
Al Jubayl, Saudi Arabia. Seabees stationed there had parts of their T-
shirts and combat boots turn purple and also sought medical treatment 
after being exposed to airborne unidentified noxious fumes. DOD's 
assessment was that these personnel were definitely not exposed to 
chemical warfare agents. Analysis by the Natick Laboratories said that 
the change could be as a result of by products of industrial area 
operations, such as a fertilizer plant, which was located nearby. OK . 
. . it was not a chemical warfare agent, but it was chemicals. Ask 
anyone who lived near Bhopal, India what a chemical will do.
    The DOD also just spent many years and several million dollars 
``proving'' that the soldiers and marines that had chemical burns--well 
they simply didn't. I find it interesting that they can go back almost 
10 years and determine by reading valid medical records, written by on-
the-scene examining physicians that the doctors were simply 
``mistaken''.
    In 1996, a research team found that higher than normal levels of 
squalene were present in Gulf War veterans and that the source of this 
squalene was probably immunizations. The DOD said ``WRONG''. However, 
just recently the DOD stated that there are low, naturally occurring 
levels of squalene in the anthrax vaccine. Since this vaccine is 
artificially created, how did the squalene magically appear? DOD's 
credibility is shot.
    Veterans Administration.--The VA is controlled by costs. They have 
a fixed budget. This seems to result in a priority to minimize 
disability compensation by proving that veterans do not have a service-
connected disability. If you are not service-connected, then the VA can 
charge your insurance, if you have any. They rob Peter to pay Paul; in 
other words, if they increase services in one clinic then they must 
reduce the staffing of another clinic. They cannot afford to do proper 
research or even allow expensive or unique tests. Being understaffed 
their medical care and lab results are unpredictable and unreliable. 
They do not have the specialists necessary for proper care and it seems 
when they get some physicians who find abnormalities they are let go, 
except in psychiatry. For example:
    In 1997, I was seen at the Veterans Administration Medical Center, 
Philadelphia, Persian Gulf Clinic. Testing was performed at the 
University of Pennsylvania utilizing the ``Whole Body PET'' and a 
``Xenon Study to Assess Muscle Blood Flow in the Legs''. The results 
showed that I had decreased blood flow to certain areas of my body and 
Inflammatory Muscle disease. This was consistent with what they had 
seen with other Persian Gulf veterans and was decidedly different than 
other non-Persian Gulf veterans. However, their funding was NOT renewed 
and the physicians were discharged.
    The VA did get funding to perform a blind study involving mycoplasm 
and doxycycline. This study was limited to the Philadelphia area. I was 
not accepted into since I had used doxycycline in the past, even though 
I was positive for mycoplasm. The VA was also running a study on 
exercise and illness for the Persian Gulf vets, this was also conducted 
in the Philadelphia area. To participate I would have to drive 2 hours 
to Philadelphia, exercise and drive 2 hours home. I have inflammatory 
muscle disease and chronic fatigue. This trip would have been 
physically impossible for myself or any other out-of-area veterans. The 
VA said they had no way to transport me or to have their program go 
outside the Philadelphia area. Hence, their research study is 
artificially limited.
    The VA just recently had me wear a heart monitor to see if my heart 
problems were continuing. However, it took over a month and a half to 
get the results read. Those results stated ``normal sinus rhythm'' and 
``no sustained arrhythmia's''. The test showed that I had sinus 
tachycardia with heart rates ranging from 53 to 148, however these 
results were not explained. Of course sustained arrhythmia means I am 
dead.
    The VA performed a biopsy of my right leg. Do you know I have a 
kidney in my leg? The VA results said they found ``a small floater of 
kidney tissue'' and that they could rule out ``tuberculosis or fungus 
as a cause''. This is unacceptable.
    The VA also said in their records, after performing an x-ray of my 
back, that ``. . . he did not show up for the test''.
    These laboratory results show sloppy lab work, poor performance, 
and are totally useless.
    National Institutes of Health.--I only dealt with NIH once. Their 
clientele comes from controlled sources. In my case this control meant 
that their study was not truly independent and hence their results 
could be tainted with DOD influence. For example:
    Beginning in 1994 the Department of Defense evaluated me over a 
three-year period. During the CCEP, Bethesda Naval Hospital sent me to 
the NIH in an effort to verify that my conditions were caused by 
``stress''. The very lengthy and invasive procedures found that I had 
``autonomic nervous system dysfunction''. During my interview process, 
I remarked that I thought that I had been exposed to chemicals. 
However, NIH, in their final report to me recorded that I said I was 
NOT exposed to chemicals, among many other errors. It could have been 
an honest mistake except that. their procedures would not allow me to 
correct the records. All they said was that my rebuttal would be 
retained in my record. This culminated in a toned down final result. 
However, since my results did not support the Navy diagnosis of 
``stress'', the Navy never sent ANY other Persian Gulf veterans to NIH 
for evaluation in this specific area.
    I am sorry, but giving funding to governmental bodies such as NIH, 
the VA, or DOD is like taking your life-savings and giving them to a 
bear. He will merely bury it in the woods and . . . believe me . . . 
you will get no return on your investment and you will not even get 
back your initial investment. My experiences support the contention 
that these and similar agencies have one focus . . . to prove that 
there is NO ILLNESS, that there are NO ABNORMAL indicators, and that 
there is NO PROBLEM except a psychiatric one caused by the veteran 
himself.
    The following are my recommendations.
    Remove DOD and VA as designers of any research. They still have an 
important role to provide data and other assistance during the 
research. They need to be involved by following the research and 
suggested protocols plus providing referrals of their veterans to 
researchers.
    The following are private doctors and researchers that have helped 
me. They offer various avenues of research that should be explored.
  --Dr. Pamela Asa who discovered squalene in my blood several years 
        ago. Research needs to continue to find out where the squalene 
        comes from.
  --Dr. William Baumzweiger in the area of neurological effects and 
        treatment. He has been effective in developing preventative 
        measures to reduce flair-ups of the illness. He has used 
        medications as well as other treatments that are helpful in 
        stopping progression of Persian Gulf symptoms.
  --Dr. John Martin of the Center for Complex Infectious Diseases. He 
        has detected stealth viruses in my tissues through blood work 
        and biopsies. His research has possibilities linking viral and 
        bacteriological organisms to the cause of Persian Gulf Illness.
  --Dr. David Berg of HEMEX Corporation has developed a valuable test 
        to prove the hypercoagulability of some veterans. His results 
        are being published in a medical journal this month.
  --Dr. Kathleen Hannan, along with the research of Dr. Berg, has 
        developed a protocol of treatment for hypercoagulability and 
        Persian Gulf Illness. I am presently undergoing treatment using 
        heparin as well as a ``transfer factor'' in a new protocol. The 
        medication and specific lab tests are very expensive.
  --Dr. Garth Nicolson. He has been effective in working with 
        mycoplasm.
    One last area is funding for treatment and testing. The average 
Persian Gulf veteran and his family cannot obtain either the testing or 
treatment for their various illnesses. Since the ``illness'' is not 
named, most insurance companies and/or Medicare will NOT cover this 
testing and treatment. The illness must be named . . . right now. 
Persian Gulf illness is called an ``undiagnosed illness,'' no one pays 
for testing or treatment of an illness that ``might not be there!''
    After battling for years I am better off now than when I started in 
1991. This is mainly due to the interest and kindness of private 
researchers, often unfunded. I feel like my government has left me out 
in the cold after many years of service. As a veteran of two wars I 
shouldn't have to beg to get truthful answers, expensive diagnostic 
tests, proper medical care, or essential treatment.

    Senator Specter. Captain Dyckman, we would be interested to 
know precisely what symptoms, what ailments, you have suffered 
as a result of your exposure and your Gulf war illness.
    Captain Dyckman. I have hypercoagulability. I have 
autonomic nervous system damage. I have uncontrollable blood 
pressure. I have irritable bowel syndrome. I have stomach 
ulcers. I have brain lesions. I have degenerative bone disease. 
I have had to have a total hysterectomy in a pre-cancerous 
state. I have had to have my gallbladder removed. I have a foot 
of my colon removed. And I have chronic headaches, chronic 
sinus and chronic fatigue, fibromyalgia. And those are the main 
ones.
    Senator Specter. Have you been accorded treatment by the 
Veterans Administration, when you have taken those ailments to 
them?
    Captain Dyckman. No. There is certain protocols that I 
bring in from outside doctors. And they usually have their pile 
of the research.
    Senator Specter. But do they deny you medical treatment, or 
is it a matter of your being dissatisfied----
    Captain Dyckman. No.
    Senator Specter [continuing]. With what they have done?
    Captain Dyckman. It is not a denial of treatment in its 
acceptance of what is wrong with you. I had some tests done----
    Senator Specter. They doubt your complaints?
    Captain Dyckman. Right. I had--an example was I had the 
biopsy to send the muscle tissue out to John Martin. What the 
VA said in their pathology report is that I had kidney tissue 
in my leg and that it was not caused by tuberculosis or fungus. 
Those are the kind of results that people are saying. It made 
no sense. It was improper. It was unprofessional. It was 
inaccurate. When you go----
    Senator Specter. Let me move over to Dr. Haley for a 
question or two here.
    Dr. Haley, is the long and short of the charts you showed 
us and your medical research that you find a connection between 
the symptoms complained by the Gulf war veterans and Gulf war 
illness a Gulf war syndrome?
    Dr. Haley. Right. In the group that we studied, it appears 
there is an injury in brain cells in just that area of the 
brain that would cause the symptoms of Gulf war syndrome, the--
--
    Senator Specter. So your conclusion differs from the other 
studies in that you do in fact find cause and effect as a 
professional conclusion from your studies as a research 
scientist.
    Dr. Haley. That is correct, although those have to be 
replicated in larger studies. But to the extent that we have 
done it in this unit, we think that is correct.
    Senator Specter. Well, are your studies sufficient to lead 
you to a professional judgment on cause and effect?
    Dr. Haley. Complicated issue. I think I would say, I would 
conclude that in this group of people we studied, in this 
Seabees unit, yes, that is correct. There is a cause and effect 
relationship in this group. Now whether that can be 
extrapolated more broadly to how many veterans, that requires 
an actual sample survey to have a valid result. But in this 
group, we think there is a cause and effect relationship.
    Senator Specter. Well, what sort of an additional study are 
you talking about?
    Dr. Haley. OK. We have proposed taking a random sample, 
about 3,000 of the guys who went over, a random sample of those 
who did not go over from a computer tape of personnel during 
the war, which is available. We have designed a telephone 
survey. The Pentagon spent $500,000 with us to design this 
survey.
    Senator Specter. Well, Doctor, let me cut through. I am at 
a little bit of a loss. You have conducted certain studies.
    Dr. Haley. Right.
    Senator Specter. And you say there is cause and effect. Why 
not stop there?
    Dr. Haley. Scientifically sometimes what you get in a 
smaller sample may not be true of a larger group. It is just in 
science we know some things that look really good in a small 
group turn out to fizzle when you go bigger. So you have to do 
that.
    Senator Specter. Well, Doctor, quantify the small group and 
quantify the big group.
    Dr. Haley. OK. Right. We studied 249 veterans in the 
Seabees unit, 63 of them had 1 of our 3 Gulf war syndromes.
    Senator Specter. How many would constitute--we are trying 
to move ahead here.
    Dr. Haley. Right.
    Senator Specter. How many----
    Dr. Haley. Three thousand in each group in a telephone 
survey and then take small random samples from the sick and the 
well in those, about 100.
    Senator Specter. Dr. Sox, what do you think of Dr. Haley's 
testimony?
    Dr. Sox. Well, our committee concluded that the evidence 
that linked PB to long-term health effects----
    Senator Specter. Are you familiar with Dr. Haley's studies?
    Dr. Sox. We reviewed Dr. Haley's studies. He had an 
opportunity to testify before our committee. We engaged in a 
very fruitful discussion with Dr. Haley about his work.
    Senator Specter. What do you think of his conclusion on 
cause and effect?
    Dr. Sox. Well, it does not meet the criteria established by 
the Institute of Medicine for cause and effect, the same 
criteria that had been used in scientific studies for the past 
50 years, that were used in the Vietnam War----
    Senator Specter. Would his elongated study, expanded study, 
meet the Institute of Medicine's criteria for cause and effect?
    Dr. Sox. I do not believe so. And the reason I do not 
believe so is that in order to establish cause and effect, you 
have to show that the bigger the exposure, the bigger the 
effect. And that has been sort of an important principle of 
scientific inference for 50 years. And because we do not have 
reliable information on the degree of exposure in veterans of 
the Gulf war, I do not think he is going to be able to meet our 
criteria.
    Senator Specter. My red light went on in the middle of Dr. 
Sox's answer. So I am going to yield to Senator Hutchison. But 
we will have a second round.
    Senator Hutchison. Because I would love for you to finish 
that thought, because it seems to me that we are very close 
here to having some common sense be put on this issue.
    Let me ask you, Dr. Sox, if you are not persuaded with the 
obviously small sampling, but with the scientific basis that 
Dr. Haley has shown for his presumptions, are you impressed 
with that little study?
    Dr. Sox. The study still has--and I am speaking for the 
committee now and for our conclusions. The study still has some 
problems. No information on exposure. We do not know the 
exposure of the veterans that were in his study by any reliable 
means.
    Senator Hutchison. Let me ask you----
    Dr. Sox. We do not have unexposed group that never even 
went into the theater of war. And it is possible that the 
effects that Dr. Haley observed occur in people who did not go 
into that theater of war.
    Senator Hutchison. Do you think that his research is a 
nugget on which you could put together a bigger proposal that 
might--maybe we do not need to talk about the legal definitions 
of causal connection. Maybe we just need to say, what is the 
next step to what is clearly a scientific finding that appears 
to be--would you not say it is a well-done study that could be 
built upon?
    Dr. Sox. Well, I want to emphasize that our committee has a 
lot of respect for what Dr. Haley is doing. And we feel that 
his findings represent an interesting observation that, first 
of all, needs to be replicated in a more representative 
population.
    But we also believe it needs to be replicated by other 
investigators. It is a paradigm of science that somebody makes 
a finding, and then other people check it to be sure that they 
can reproduce it before it really becomes regarded as 
scientific truth.
    Senator Hutchison. So the next step would be to take that 
basic finding and perhaps get others, outside independent 
sources, that might replicate it or have similar studies to see 
if that, in fact, comes out again with a different group.
    Dr. Sox. Yes, Senator.
    Senator Hutchison. Would you think that would be a worthy 
next step?
    Dr. Sox. I do.
    Senator Hutchison. So you think the research he has done is 
worthy of pursuing the next step that would be to see if this 
finding had merit.
    Dr. Sox. Yes. Our report contains a statement that these 
findings require further study with improved study design. So 
that was the conclusion of our committee.
    Senator Hutchison. Do you think that the proposal that Dr. 
Haley made of expanding his efforts would also add to the body 
of knowledge, going the next step perhaps?
    Dr. Sox. Well, since I have not had a chance to really look 
at the research protocol carefully, I think it would be 
inappropriate of me to make any statement----
    Senator Hutchison. On that particular study.
    Dr. Sox [continuing]. On that score. Yes.
    Senator Hutchison. Well, let me ask you this: Do you think 
that the--let me say, in your study you looked at peer-reviewed 
scientific publications. But you specifically did not look at 
any classified military data, battlefield reports, eyewitness 
accounts. That was not in your purview, is that correct?
    Dr. Sox. That is correct.
    Senator Hutchison. So you were not able to even look at the 
check observations of the Khamisiyah ammunition dump. You were 
not able to put any of that into your factoring as eyewitness 
accounts.
    Dr. Sox. That is correct.
    Senator Hutchison. Do you think that with your studies just 
on the scientific reports, in which you said there was limited 
suggestive published evidence that low level sarin, in enough 
concentrations to cause immediate symptoms--I think I am 
quoting the report--could leave someone with permanent brain 
damage that would cause chronic symptoms like Gulf war 
syndrome, do you think that with that conclusion, and then with 
the added battlefield eyewitness account information, and then 
with the large number of veterans who have come back, that we 
should pursue the studies that would be focused on trying to 
determine that this a syndrome, that we would then begin to 
focus on causal connections and from that would come 
treatments?
    Dr. Sox. Well, before we could draw a cause and effect 
relationship between exposure to sarin and these long-term 
symptoms, which have a lot in common with the symptoms reported 
by veterans with unexplained Gulf war illness, we would have to 
establish that the veterans who had these long-term symptoms 
also had the short-term syndrome. That would be a formidable 
task, to establish that with certainty, given that there has 
been 8 years passage of time since the exposure actually 
occurred.
    So I think it would be quite a challenge to accumulate 
credible evidence that this veteran experienced the acute 
symptoms and this veteran did not. So in theory, I think it is 
possible. In practice, I think it is going to be difficult to 
get really credible scientific evidence on that point. But that 
would be the direction that you would want to go.
    Senator Hutchison. Yes. I was just going to say, you are a 
scientist. We have one in seven people in the last conflict in 
which America was involved, who have some kind of malady. We 
are looking at the future. We are looking at how we can best 
equip ourselves to fight the next conflict, in which it is very 
likely that chemicals will be involved.
    You are the scientist. You just said, finally, that you 
think we should pursue this direction. What would you lay out 
as the next step to take to do our duty, my duty, to make sure 
that our men and women in the services have all of the 
equipment they need to do the job they are being asked to do, 
and that we protect them as we should?
    Dr. Sox. Well, I am going to limit my response to something 
I am pretty confident of. And that is that in the next conflict 
we need to have much more precise information about who got 
exposed to what, when, and to what amount.
    And when we have that information and then we track 
returning veterans' illness experience over time and try to 
link that to the exposures, we will be in a much better 
position to understand what are the environmental exposures 
that really make a difference. And then we are in a better 
position to protect against those.
    Senator Hutchison. That is the future. And we certainly----
    Dr. Sox. That is the future.
    Senator Hutchison [continuing]. Have learned enough to do 
that. But what about now? And what about doing the best job we 
can to protect the people? I mean, I do not want to send them 
out there as guinea pigs to be the next test case. So what can 
we do now to give them the support they need to do this job?
    Dr. Sox. I wish I could satisfy you with an answer that 
would lead to immediate action. But the only immediate action I 
am confident is important is to lay the groundwork for better 
understanding in the future. And I just point out that it has 
only been a matter of 10 years that we have started to consider 
war as the possible progenitor of chronic illness.
    So we are at the beginning of a quest for understanding 
that is going to take a long time, just as it has taken us 40 
years to start to get our arms around the causative factors in 
cancer, for example.
    Senator Hutchison. Dr. Sox, you and I will not disagree one 
degree that we need to do better data collection in the next 
war.
    I would just maybe ask you, Dr. Haley, I am not satisfied 
to wait and send someone out without doing something now that 
will give them a better chance to have antidotes and also 
protection from the kinds of disease that we are seeing right 
now in one of seven veterans of the last conflict we had. What 
would be your suggestion for the next----
    Dr. Haley. Well, I think that the way we solved toxic shock 
syndrome, Legionnaire's disease and AIDS, as you pointed out 
earlier, is the formula. You know, what is interesting here is 
we are dealing with an epidemic. If there is anything going on 
here, it is an epidemic, one out of seven. What has been shown 
over 50 years of CDC research is epidemics are different than 
the way diseases occur in the general population.
    In the general population, when you are studying cancer, 
heart disease, those are very difficult things to study. You 
have to have long-term, big studies with large numbers. In 
epidemics you do not need big studies, because you have a 
homogenous exposure and a very homogenous disease that are 
tightly connected. Otherwise it would not be an epidemic.
    And looking at toxic shock syndrome, remember the Rely 
tampon was quickly implicated by a very small case control 
study, smaller than the one that we did.
    Senator Hutchison. And the specific hotel in Legionnaire's 
disease.
    Dr. Haley. And Legionnaire's disease and the link with the 
air conditioning in the Bellevue Stratford Hotel. That was all 
done by self-reported risk factors. You get a group of cases 
who are sick and a group of matched controls and you give them 
a carefully worded questionnaire that gets at the possible risk 
factors, and you find out which risk factor did most of the 
sick people say they were exposed to and most of the well 
people say they were not.
    Now, the reason that has not been done here is the people 
who have been in charge of all these studies, one, assumed from 
the beginning that it was a psychiatric disease. It was stress 
and psychological. And second, they do not trust veterans. They 
think veterans will lie and inflate. And so they never 
undertook those studies because they just did not believe they 
would work out.
    Well, if they had used that logic when faced with toxic 
shock syndrome, Legionnaire's or AIDS--AIDS was cracked the 
same way, at least the risk factors. The behavioral risk 
factors were determined by self-reported risk factors.
    What I would suggest is, even now, I think it is still time 
for us to mount 30 or 40 different case control studies, get a 
whole bunch of people who know how to do this, preferably 
former CDC people or people with a school of public health 
training, who know how to investigate epidemics, and let them 
loose, as you mentioned, in every city in the country, and do a 
bunch of these and see if we can find some risk factor 
associations we would agree on.
    Now this may not--I think Dr. Sox's points are very 
important. And I really appreciated their report. I think it 
was very carefully done. But the type of evidence that IOM is 
considering to be definitive evidence and to meet those 
criteria, those are much more excessive than the general view 
of science. Science generally goes when you have a whole bunch 
of studies that agree with each other that finally start 
reaching agreement. That mosaic of evidence is what generally 
tends to confront scientists.
    Senator Specter. We are going to have to conclude this 
hearing----
    Dr. Haley. That is what I think we should do.
    Senator Specter. We are going to have to conclude this 
hearing by noon. We have been at it now for 2\1/4\ hours. I see 
Dr. Rostker shaking his head negatively in the back row.
    Dr. Rostker, we are going to give you a chance to comment 
here. We do not want you just on the record here, head being 
shaken negatively. I had to step out for a minute. We are in 
the final stages of an appropriations bill for the Departments 
of Labor, Health, Human Services, and I have to turn to that, 
where we are trying to bring that to the floor tomorrow to see 
if we can get some funding for some of this stuff.
    Dr. Sox, I could not be here. I conclude that Senator 
Hutchison solved the issues as between you and Dr. Haley. What 
do you think of his proposed expanded study to give an 
acceptable resolution of the cause and effect issue?
    Dr. Sox. Well, first of all, I did not have a chance to 
look at the protocol. So all I can do is state in generalities 
that it is important to replicate his studies in a broader 
representative population that includes non-exposed veterans.
    Senator Specter. Well, will you take a look at his protocol 
and give the committee a response?
    Dr. Rostker, step forward here. Pull up an extra chair. Mr. 
Perot will lend you his microphone, even though he paid for 
that microphone.
    He has paid for more than one microphone around here.
    What do you think about Dr. Haley's study, Dr. Rostker?
    Dr. Rostker. Well, let me----
    Senator Specter. Or in the alternative, how are we going to 
come to a conclusion here?
    Dr. Rostker. I anticipated that since Dr. Haley would be on 
the panel that you would be interested in our interactions. And 
I have a statement that I would like to have placed in the 
record. Moreover----
    Senator Specter. We would be glad to have it placed in the 
record.
    [The information follows:]
  Review of the Department of Defense's Interactions with Dr. Robert 
                      Haley Between 1997 and 2000
    Thank you for this question, Mr. Chairman. While the stated purpose 
of this hearing is to ``examine findings of the recently announced 
Institute of Medicine (IOM) study,'' I anticipated that since Dr. 
Robert Haley was included as a witness, questions concerning DOD's 
interactions with him might be asked. Accordingly, I have prepared a 
review of these interactions. These two notebooks contain the various 
correspondences between the Office of the Special Assistant for Gulf 
War Illnesses and Dr. Haley, and DOD's medical research community and 
Dr. Haley. I would like to make these notebooks available to the 
committee for your consideration.
    In summary, we view our interactions with Dr. Haley over the last 
three years with disappointment and frustration. After going against 
our normal procedures and overriding the peer review and competitive 
process to provide $3 million to Dr. Haley, we have been frustrated in 
getting Dr. Haley to meet the terms of his research cooperative 
agreement. We have been faced with a constant barrage of lobbying by 
Dr. Haley and others on his behalf with the purposes of forcing the DOD 
to once again ignore its peer review process and provide additional 
research funds outside of the competitive grant system. This is even 
more disturbing, since, as a result of his lobbying, Dr. Haley's work 
has been reviewed by a number of independent groups charged with 
oversight of the DOD's Gulf War research efforts. These groups have not 
endorsed Dr. Haley's demands. They have consistently told the DOD not 
to override the peer review competitive process again. Moreover, the 
consistent theme of these reviews is the need to expand the sample 
beyond the original cohort that was the basis for Dr. Haley's original 
research. In fact, if Dr. Haley had complied with the terms of the DOD 
Cooperative Agreement (CA) he would have already met these critiques. 
In the CA he proposed to ``determine whether the findings of study #1 
can be replicated in an independent population of Gulf War veterans.'' 
[1] To date Dr. Haley has failed to provide an ``expanded set of cases 
and controls'' as required by his agreement with the Government.
    At this point, if you would like me to continue, I would be pleased 
to provide direct testimony concerning our relationship with Dr. Haley. 
If you would prefer, however, my statement could be placed in the 
record. I would like, however, to call to your attention the scope of 
my statement. Specifically, my statement covers:
  --Dr. Haley's initial lobbying, and our decision to award a 
        noncompetitive contract for $3 million,
  --The negative reaction to that decision from the Presidential 
        Advisory Committee on Gulf War Veterans' Illnesses, [2]
  --The independent assessment by a panel of the American Institute of 
        Biological Sciences of Dr. Haley's first [3] and second [4] 
        annual reports, and his response to this independent panel's 
        assessment [5]
  --And, the current discussions concerning future funding, including 
        Dr. Haley's assertion that Senator Hutchinson has added funding 
        to the fiscal year 2001 budget for his latest project. I note 
        that the DOD has not received any guidance from the Congress 
        for a new noncompetitive funding for Dr. Haley.
    In addition to the issue of funding, the Government has had other 
interactions with Dr. Haley over the last several years. These include:
  --A number of independent assessments of Dr. Haley's work that all 
        make about the same point recently made by the IOM.
  --Dr Haley has been the lone author of extreme criticisms attacking 
        findings published in leading scientific journals by government 
        and non government scientists both in the U.S. and abroad. [6] 
        [7] [8] [9] [10] Given the highly technical nature of the 
        exchange of statistical analysis used in the ``American Journal 
        of Epidemiology,'' I asked the RAND Corporation to prepare a 
        technical assessment of the issues raised by Dr. Haley. Their 
        review agreeing with the DOD and VA researchers is available to 
        the committee. [11]
  --Dr. Haley's attack on the veracity of researchers at the RAND 
        Corporation because their review of the medical literature on 
        ``Stress'' did not reference an article authored by Dr. Haley. 
        [12] Dr. Haley believes his article is the definitive article 
        on the subject.
  --Dr. Haley's criticism of a paper on British Gulf War veterans, 
        demanding its retraction, because it did not replicate his 
        study. [13] [14]
  --My exchange of letters with Dr. Haley because he wrote and reported 
        there were chemical agents on the battlefield. [15] [16] [17] 
        He has not provided any documentation of that occurring and in 
        his latest publication on September 14, 2000 reports ``. . . 
        sarin was documented in ambient air,'' on the battlefield. [18]
  --Dr. Haley's claim to the Veterans of Foreign Wars that the Office 
        of the Special Assistant has mounted a campaign to impugn his 
        work [19] and the VFW's request that we provide additional 
        funding to Dr. Haley. [20]
  --Dr. Haley's assertion that there is strong evidence of an epidemic 
        of ALS in young Gulf War veterans [21] and his request for 
        special access to personnel records. [22] Additionally he has 
        suggested the possibility of future Parkinsonlike syndromes 
        among Gulf War veterans. [18] ''

REVIEW OF THE COOPERATIVE AGREEMENT (CA) BETWEEN THE U.S. ARMY MEDICAL 
      RESEARCH AND MATERIEL COMMAND (USAMRMC) AND DR. ROBERT HALEY
    In 1997, Dr. Haley submitted a $12M research proposal [1] to the 
USAMRMC for a study concerning Gulf War-related illnesses. Dr. Haley 
submitted his proposal in response to a Broad Agency Announcement (BAA) 
(Announcement 95-1) which announced the availability of $10M of DOD 
funds for competitively awarded, peer reviewed Gulf War-related 
illnesses research projects. Dr. Haley's proposal was among 39 
proposals received by the USAMRMC under the 95-1 solicitation.
    The American Institute of Biological Sciences (AIBS), under 
contract with the USAMRMC, assembled a panel of independent, non-DOD 
scientists to peer review the scientific merit of the research 
proposals submitted under the 95-1 Announcement. [23] The panel 
assigned a low scientific merit score to Dr. Haley's proposal overall 
and recommended that only specific portions of the proposal met 
scientific merit criteria for funding. The Research Working Group (RWG) 
of the Persian Gulf Veterans Coordinating Board recommended against 
funding Dr. Haley's proposal based on its low overall scientific merit 
score and its cost exceeding the total funds available for the 95-1 
solicitation. [24]
    Following intense lobbying efforts by Dr. Haley, DOD agreed to make 
limited research funds ($3M) available to fund only those specific 
portions of his proposal that were deemed to be scientifically 
meritorious by the independent peer review panel. [25] This lobbying 
included a call by Mr. H. Ross Perot and visits to the Pentagon by Dr. 
Haley individually to the Service Chiefs of Staff and the Office of the 
Secretary of Defense. In order to be as open as possible, the Special 
Assistant for Gulf War Illnesses ordered funding for those portions of 
Dr. Haley's proposal that were judged by the AIBS to meet ``scientific 
merit.'' The primary goal of the $3M project was to try to validate Dr. 
Haley's initial epidemiologic observations of six syndromes in 100 new 
individuals and to develop a hypothesis that could be tested. 
Validation requires confirming these initial observations with a new 
sample and comparing service members who deployed with those who did 
not. Accordingly, additional funds were provided above those allocated 
to the Persian Gulf Veterans Coordinating Board for the competitive 
medical research process. The PAC, however, noted ``serious concern 
that a substantial amount of . . . (research) recently has been funded 
without undergoing external competition and peer review; it is 
immaterial to us that these funds did not come from the allocation set 
aside for the most recent solicitations and awards. [2] ''
    On September 30, 1997, the USAMRMC entered into a Cooperative 
Agreement (CA) [26] with the University of Texas Southwestern Medical 
Center at Dallas which provided $3M of DOD funds to Dr. Haley for 
research efforts on, ``Multi-Disciplinary Pathophysiologic Studies of 
Neurotoxic Gulf War-related Syndrome Leading to Diagnosis and 
Treatment.'' The CA was for an 18-month period of performance ending 
March 29, 1999, but it allowed an 18-month extension with the mutual 
agreement of the parties. The CA requires Dr. Haley to provide the 
USAMRMC with annual progress reports detailing scientific issues and 
accomplishments. It also requires a final report detailing the findings 
and issues of the entire project.
    Dr. Haley submitted his first annual progress report to the USAMRMC 
in October 1998, covering the period September 30, 1997 to September 
29, 1998. [27] The AIBS, under contract with the USAMRMC, provided an 
independent scientific peer review of the annual report. The peer 
reviewers judged the report to be incomplete and difficult to evaluate 
without substantial additional information. [3] The USAMRMC returned 
the annual report to Dr. Haley in February 1999, requesting that he 
revise it to address the peer review comments. [28] They also expressed 
concern that Dr. Haley had not accomplished the primary task under the 
CA to expand his original sample to a total of 100 cases and controls 
in order to confirm his original findings. Dr. Haley responded to this 
request with an extensive written rebuttal to every point in the peer 
review report. [5]
    In a conference call on March 18, 1999 between the USAMRMC and the 
University of Texas, Dr. Haley agreed to: (1) provide a more complete 
summary of his research in his next annual progress report; (2) submit 
a modest proposal for a validation study of his original findings to be 
considered for funding under the existing CA; (3) submit a modest 
proposal for a pilot study to work out methodology for a national 
survey; and (4) provide a detailed written request for permission to 
use DOD funding for those portions of his study which were conducted 
before he had completed DOD human use approval. [29] The USAMRMC agreed 
to authorize an 18-month no-cost extension to the CA and to approve his 
use of the existing funds to purchase additional equipment to enable 
Dr. Haley to more efficiently analyze his data. On April 1, 1999, 
USAMRMC granted the 18-month no cost extension of the CA. [30] The 
current period of performance is September 30, 1997 to September 30, 
2000.
    Dr. Haley submitted his second annual progress report in October 
1999, covering the period September 30, 1998 to September 30, 1999. 
[31] The USAMRMC obtained an independent scientific peer review of this 
report from the AIBS and received the review comments in April 2000. 
The reviewers concluded that this latest report was substantially 
unchanged from the previous annual report. They also expressed concerns 
that the report lacked adequate data to permit a thorough analysis of 
the progress of this project. [4] In a letter, dated August 10, 2000, 
[32] the USAMRMC provided these comments to Dr. Haley and requested 
that he review the comments and prepare a final report which is 
comprehensive in the analysis and reporting of the results from the 
experiments conducted under this CA. In their letter to Dr. Haley, they 
also proposed a site visit on October 30, 2000 by personnel from the 
USAMRMC's Regulatory Compliance and Quality Directorate to review all 
data gathered during the project and to discuss compliance with human 
use procedures. Dr. Haley has agreed to the site visit.
    Notwithstanding the incomplete status of the CA, Dr. Haley has 
submitted a new proposal entitled ``Establishment of a Gulf War Illness 
Research Center'' and he requested $25,253,397 for a 24-month period of 
performance. This is currently in scientific review by an external 
panel of experts. Dr. Haley has asserted to the DOD contracting officer 
representative that Senator Hutchinson (R-Tex) added funding to the 
fiscal year 2001 budget for his project. DOD has received no guidance 
on new, non-competitive funding directed in statute to Dr. Haley.

              INDEPENDENT ASSESSMENTS OF DR. HALEY'S WORK
    Over the years, there have been a number of assessments of Dr. 
Haley's work that all make the same point made by the IOM in their most 
recent review.
  --In 1998 the U.S. Senate Committee on Veterans' Affairs' Special 
        Investigation Unit on Gulf War Illnesses noted that:

    ``[Dr. Haley] conclude[s] that . . . [his] . . . results show an 
increase in nervous system impairment and a pattern consistent with 
exposure to specific neurotoxicants (Haley et al., 1997). 
Unfortunately, nearly all of these studies were performed on `samples 
of convenience' and, as a result, cannot be used to draw conclusions 
about the larger but unstudied group of all Gulf War veterans. This 
body of literature has added little to the collective understanding of 
symptoms and health concerns among Persian Gulf War veterans. [33]''

  --In June 1999, Dr. Haley testified before the Presidential Special 
        Oversight Board (PSOB). [34] The PSOB consulted with Dr. 
        Jonathan Samet, the Chairman of the Department of Epidemiology 
        of the Johns Hopkins University, School of Hygiene and Public 
        Health. On June 24, 1999 Dr. Samet wrote the PSOB:

    ``To recapitulate the story of Dr. Haley's research, . . . he has 
moved rapidly from a descriptive study to research for exposures 
causing various Gulf War syndromes, and even to the potential genetic 
basis of these syndromes. He also mentioned clinical trials of 
therapeutic agents. The pace of this work is breathtaking and perhaps 
warranted by the needs of the Gulf War veterans. On the other hand, 
needed, confirmatory work by others has not yet taken place. . . .
    ``In spite of Dr. Haley's enthusiasm, I do have concerns about some 
of the findings. As I pointed out earlier this week in my remarks to 
the Board, Dr. Haley has been using poorly specified outcome measures, 
symptoms and syndromes, and exposure variables that represent 
surrogates for unknown agents. There must be misclassification (error) 
affecting both exposures and outcome and consequently the finding of 
extremely strong associations between the outcome measures and the 
putative exposures is surprising. For example, the use of flea collars 
is likely to be an inaccurate indicator of exposure to the insecticides 
in the collar. One explanation for the findings that cannot yet be 
discarded is the possibility of information bias, that is, persons who 
report symptoms are also more likely to report exposures.
    ``Dr. Haley has outlined an ambitious program of research. Assuming 
that his research agenda moves forward, I suggest that a coordinated 
program of research be developed that will assure replication by others 
at each stage. Lacking such coordination, there is every potential for 
further contentious debate that cannot be appropriately resolved with 
evidence. Additionally, appropriate oversight should be developed for 
Dr. Haley's program to assure that proper peer review and guidance is 
maintained throughout. Like many projects on controversial topics with 
substantial public policy implications, independent oversight enhances 
the credibility of the research and the researcher.'' [35]

    It is important to note that in the Cooperative Agreement with DOD 
Dr. Haley ``proposed following up promising findings from our prior 
research . . . by applying an extended battery of . . . tests to our 
sets of cases and controls and to test the external validity of our 
prior findings in new populations of Gulf War veterans.'' [1] To date 
Dr. Haley has failed to provide data on an ``expanded set of cases and 
controls.''

    DR. HALEY'S REVIEW OF WORK PUBLISHED BY DOD MEDICAL RESEARCHERS
    In 1998 Dr. Haley published in the ``American Journal of 
Epidemiology'' a critique of published work by DOD and VA researchers 
raising not only technical points, but also inferring the government 
sponsored research among Gulf War veterans cannot be trusted. [6] The 
author's responses [7] [8] [9] and Dr. Haley's criticism of their 
responses were also published. [10] Since these were very technical 
statistical arguments, outside of the competence of the Office of the 
Special Assistant, we asked the RAND Corporation, a Federally Funded 
Research and Development Center for DOD to review the arguments and to 
advise us accordingly. Their review concluded Dr. Haley's formulation 
exaggerated the precision of statistical measures, ignored numerous 
sources of error and constituted an unsatisfactory basis for 
statistical analysis. The RAND analysis concurred with the rebuttals of 
Dr. Haley's criticisms by DOD and VA authors. [11]

    AN ATTACK ON THE VERACITY OF RESEARCHERS AT THE RAND CORPORATION
    Independent of the above and on an entirely different subject, Dr. 
Haley attacked the veracity of researchers at the RAND Corporation 
because they did not include an article he had written in their review 
of the medical literature on ``stress.'' Specifically, Dr. Haley wrote 
the President of the RAND Corporation:

    ``I wish to bring to your attention what appears to be a most 
grievous abuse of the scientific process which may constitute 
scientific misconduct on a federally sponsored project within the RAND 
Corporation. . . . The RAND authors represent the monograph as a 
complete review of the scientific literature on the issue of the 
possible role of psychological stress in causing physical or 
psychological illnesses in Gulf War veterans. . . . In the body of the 
monograph and its extensive bibliography, the authors did not cite my 
1997 peer reviewed paper, `Is the Gulf War syndrome due to stress: the 
evidence reexamined. . . .'
    `` `It would be unreasonable to assume that the RAND authors were 
unaware of my paper. . . . Therefore, it appears highly probable that . 
. . (the authors) and colleagues at RAND knowingly censored my paper 
from their review of the scientific literature and based their 
conclusions on evidence that was disqualified by my paper. . . .'
    ``In view of the excellent scientific reputation enjoyed by RAND, I 
trust that you will review this matter and take proper action to 
rectify the misconduct of your staff members and correct the 
misinformation.'' [12]

    When the original RAND literature search was done, Dr. Haley's 
paper was not published. The peer reviewers of the first edition of 
this monograph [36] recommended including several recent publications 
on stress related to the Gulf War, including Dr. Haley's 1997 
publication. The RAND internal review determined that Dr. Haley's work 
was indeed, not censured, but was just not available for the first 
edition on stress. Several of his publications were referenced in the 
second edition. [37] While noting Dr. Haley's contention that the PTSD 
rate is nearly zero in Gulf War veterans, RAND did not assess whether 
or not Dr. Haley's assumptions were correct or not. The RAND authors 
concluded additional empiric research is necessary to determine if PTSD 
in Gulf War veterans is zero or merely low.

                    CRITICISM OF BRITISH RESEARCHERS
    Dr. Haley commented [13] on a paper done by British researchers 
evaluating the factor structure of the symptoms reported in a randomly 
selected UK Gulf War cohort from the factor structure of two other 
randomly selected cohorts. Dr. Haley contended he was never informed 
they had undertaken such an analysis to replicate his work. He then 
said they omitted 12 of his 23 symptoms, their mathematical methods of 
factor analysis were incorrect in at least three important respects and 
they used different factor weights. He contended they misrepresented 
their analysis as an approximation of his factor model and stated they 
should retract the paper. The British authors responded [14] that their 
Gulf War group was 3,225 individuals with a 70 percent response rate, 
while Haley's was 249 individuals with a 41 percent response rate. 
Further, they had two large control groups; Haley had none. The British 
found that subjective reporting of symptoms in the Gulf War cohort was 
similar to the two other cohorts. The British contended that Haley was 
confused over the differences between exploratory factor analysis and 
confirmatory factor analysis. The British concluded that the model 
loosely based on his results did not fit well.

 AN EXCHANGE BETWEEN DR. HALEY AND THE OFFICE OF THE SPECIAL ASSISTANT 
     CONCERNING THE PRESENCE OR ABSENCE OF CHEMICAL AGENTS ON THE 
                              BATTLEFIELD
    Last August (1999), I wrote Dr. Haley [15] of my concerns that he 
was making unsubstantiated statements concerning the use of chemical 
weapons during the Gulf War. I reminded him that UNSCOM [38] and CIA 
[39] had concluded from direct evidence that no chemicals were shipped 
south of Khamisyah. And I could add that the PSOB [40] and the Senate's 
own SIU [41] drew the same conclusion. Specifically, I noted that:

    ``Unsubstantiated statements concerning exposure to chemical 
warfare agents cause needless alarm and confusion among our Gulf War 
veterans and do them a great disservice. If you do have any verifiable 
evidence to support your claim that members of the Naval Mobile 
Construction Battalion 24 were exposed to chemical warfare agents, we 
are extremely interested and request that you provide us with copies 
and sources. Absent such evidence, I respectfully ask you to set the 
record straight. I know it was never your intent to unnecessarily alarm 
Gulf War veterans.'' [15]

    Dr. Haley responded that:

    ``I generally say very little about the issue of actual exposures 
to chemical nerve agents during the Gulf War. . . . I think the 
ultimate source of the concerns may be the two scientific papers we 
have published that bear indirectly on the possible role of chemical 
nerve agent in one of the Gulf War syndromes. . . . I would not be 
surprised if the coverage (in the press) created some concerns, but 
there was really nothing I could do to avoid that other than to be 
careful not to go beyond our scientific findings in my public comments. 
I believe I have been very careful in that respect. I seem to recall 
that I only suggested nerve agent as a possibility, and no more, 
certainly a question that is on everyone's minds.'' [16]

    In a return letter, [17] I pointed out that contrary to his 
response, he had repeatedly been quoted as making declarative 
statements to the effect that neurological ``damage was caused by 
exposure to combinations of low-level chemical nerve agents and other 
chemicals.'' As recently as September 2000, Dr. Haley in a signed 
letter to the Veterans of Foreign Wars claimed that he has ``evidence 
that sarin nerve gas was present in low concentrations among our 
troops. [19] '' He also published a paper on dopamine activity in Gulf 
War Syndrome in which he states ``. . . sarin was documented in ambient 
air,'' on the battlefield. [18] We know of no such documentation and 
would welcome this information for evaluation.

DR. HALEY'S CLAIM THAT THE OFFICE OF THE SPECIAL ASSISTANT HAS MOUNTED 
                A CAMPAIGN TO DISCREDIT HIM AND HIS WORK
    Last month (September 2000) Dr. Haley charged that:

    ``I am reassured by my colleagues here at UT Southwestern and in 
other Universities that had our discoveries been made in any other 
areas of medicine, they would have created immense excitement, 
generated feverish research by others throughout the country, and 
resulted in millions of dollars of grant funds coming to our 
universities to further the discoveries. For example, NIH would have 
encouraged us to submit a program project grant to accelerate the 
research along multiple tracks. These typically amount to $20-30 
million each. Under withering fire from the $30 million per year OSAGWI 
counterattacks on us, however, our work has been largely obscured, 
unfairly impugned out of political motivations and greatly underfunded. 
[19] ''

    I know of no action by anyone in the DOD to impugn Dr. Haley's 
work. Such charges are completely without substance or merit.
    On September 19, 2000, the VFW asked the Secretary of Defense to 
provide ``additional government funding for expanded research'' by Dr. 
Haley. [20] The PSOB advised the Secretary of Defense on September 25, 
2000 that:

    ``The Board is not in a position to evaluate the validity of Dr. 
Haley's findings. We do believe that his findings are of interest and 
we support the concept that his work needs to be replicated by 
independent scientists not affiliated with Dr. Haley.
    ``We believe that when a scientist promotes and advocates his or 
her findings through political and/or public pressure, rather than by 
scientific replication and confirmation, the objectivity of the subject 
scientific findings are called into question. There are well known 
efforts to obtain funding for research on behalf of Dr. Haley despite 
critical evaluations by peer reviewers. Dr. Haley's responsiveness to 
contractual requirements, based on funding that he obtained from the 
Department of Defense after ``intense lobbying,'' has been the subject 
of past discussion. . . .
    ``The Board believes that the VFW, Dr. Haley and the University of 
Texas should welcome independent replication of the Haley's methods and 
findings. Independent verification will either validate his [Dr. 
Haley's] findings or validate the scientific critiques that address his 
work.'' [42]

 DR. HALEY'S REQUEST FOR SPECIAL ACCESS TO PERSONNEL RECORDS TO STUDY 
                                  ALS
    On April 28, 1999 Dr. Haley asked our help in sending a letter ``to 
veterans making them aware of the study we (Haley) are doing on ALS-
like illness in military personnel. [43] '' The DOD and the Department 
of Veterans Affairs responded on June 8, 1999 by (conference) call with 
Dr. Haley. [44] As a result of the call Dr. Haley provided (1) a 
protocol for review (2) IRB approval and (3) informed consent form 
which the VA would require for approval of his request. Subsequently, 
Mr. H. Ross Perot called the Chairman of the Joint Chiefs of Staff 
claiming that veterans of the Gulf War are ten times more likely to be 
suffering from ALS. Dr. Haley met with the Secretary of Veterans 
Affairs to discuss his project. Mr. Perot called the Secretary of 
Veterans Affairs and the Under Secretary for Health of the DVA to press 
Dr. Haley's case. On August 27, 1999 the Acting Under Secretary for 
Health of the DVA wrote Mr. Perot to explain:

    ``Dr. Haley had originally requested access to specific Gulf War 
veteran patient records, including patient identifiers, for the purpose 
of recruiting VA patients into his research study. The Department of 
Veterans Affairs (VA) cannot provide such information to Dr. Haley 
because it would violate the Privacy Act and the confidentiality of our 
veteran patients records. All of our veterans trust us to preserve 
their legally entitled privacy.
    ``An option would be for VA to conduct a blind mailing to targeted 
veterans to provide them information about Dr. Haley's proposed 
research, along with an invitation to contact him should they wish to 
participate in his research. . . . (However,) the material provided to 
VA thus far, including the research protocol and the informed consent 
document Dr. Haley proposes to use, does not provide sufficient 
assurance that VA patients would be afforded the twin protections that 
are due to them. . . .
    ``Because Dr. Haley's request is unprecedented, I am taking certain 
steps that will better afford VA the necessary assurance before we 
could consider agreeing to a targeted mailing to Gulf War veterans. . . 
. If the review groups approve the protocol with recommended changes in 
the protocol, Dr. Haley must satisfy their recommendations before VA 
will conduct a blind mailing. [22] ''

    To date Dr. Haley has not re-submitted a protocol, informed consent 
and Institutional Review Board approval that met the VA's requirements.

    Senator Specter. We give you no assurances as to how many 
people will read it. Tell us.
    Dr. Rostker. That is fine. We have been, frankly, over the 
last 3 years very disappointed and frustrated. After going out 
against----
    Senator Specter. No, no. Do not read a statement. I want to 
know----
    Dr. Rostker. Sir, 3 years ago, I----
    Senator Specter. I want to know what you think of Dr. 
Haley's conclusions.
    Dr. Rostker. Right. Three years ago, I went out personally, 
based on Dr. Haley's conclusions, and overrode the scientific 
community and provided Dr. Haley with $3 million worth of 
government research money to carry on his work. And I was 
lambasted by the scientific community. I was singled out in the 
President's Advisory Committee for----
    Senator Specter. But you got promoted. What did you think 
of his work?
    Dr. Rostker. Let me finish, please, sir.
    Senator Specter. OK.
    Dr. Rostker. OK? Part of what we funded was an extension of 
Dr. Haley's research proposal in terms of bringing in case 
controls and bringing in other people. And to date, Dr. Haley 
has failed to deliver on his cooperative agreement with the 
Government. Now, I think Dr. Haley's research is interesting, 
and I would encourage him to put it in the peer review process 
and let competent medical scientists review it against other 
research that is also competing for research funds.
    We do not draw a conclusion on Dr. Haley's research. We are 
perfectly willing to support it. But we do not again want to 
see Dr. Haley lobbying in place of the peer review competitive 
research process.
    Senator Specter. Dr. Rostker has made a comment about your 
not having fulfilled your commitment, Dr. Haley. You are 
entitled to a chance to respond to that.
    Dr. Haley. Sure. Well, first of all, I think the main 
answer is, we published 21 papers in peer review journals. And 
I think that speaks for itself. Second, we proposed--our 
proposal that went through peer review, we have been turned 
down five times. We have submitted five protocols to the peer 
review, and all five have been turned down. That research has 
ultimately been funded, and we published 21 papers from it in 
the top peer review journals.
    Senator Hutchison. Do you mean privately funded?
    Dr. Haley. About half of that was privately funded by the 
Perot Foundation and about half of that was funded by the 
Office of the Secretary of Defense. And I think it was really 
Secretary Cohen, not Mr. Rostker, that funded that.
    But what is really important here is, we submitted a 
proposal for $16 million after we published our three papers 
back to back in the Journal of the American Medical 
Association. Look, no other researchers, as far as I know, have 
ever published three papers back to back in the top medical 
journal.
    We then immediately envisioned a research proposal that 
would take five different tracks, we got five different groups 
collaborating with us to go in parallel, to take different 
parts of it, to try to get within two or three to get to a 
resolution of this with a national survey, which I talked to 
you. We proposed this back in 1997. Animals studies to 
correlate with the human studies and treatment studies to see 
if we could start finding treatment, a $16 million proposal.
    It went up. It was turned down. The Secretary of Defense 
then pulled it back out of the press, the mess, and called us 
up, went back over it. With Dr. Rostker's concurrence, they 
funded $3 million of that, not the $16 million. Well, they are 
trying to hold us accountable to the standard for the $16 
million proposal and say we have not finished it.
    The point is, we finished $3 million worth of that, which 
we negotiated with the project officers ahead of time. And he 
is not aware of that. We have completed that study. It was 
completed about three weeks ago was the final date. Twenty-one 
publications have come out totally from our work. And I think 
it speaks for itself. So I think what he is saying is 
completely off base and just an attempt to try to keep us out 
of the funding stream.
    Dr. Rostker. Sir, just review the annual reports that Dr. 
Haley submitted that were reviewed independently by the 
American Institute of Biological Sciences. The cooperative 
agreement for $3 million had in it, and I quote, ``to determine 
whether the findings of the study, number one, can be 
replicated in an independent population of Gulf war veterans.''
    That was part of the $3 million that Dr. Haley committed 
to. He has been told each year that the study annual reports 
were inadequate. And he is--we have expressed our concern that 
his efforts would not lead to a replication of the study 
material, as he committed to in the cooperative agreement.
    Now putting all of that besides, Dr. Haley's proposal 
should be viewed on the merits. They should be viewed on the 
merits by a peer review process, a competitive process. And 
that is what we support.
    I am not a physician. I take no view on Dr. Haley's medical 
competence one way or the other. But having gone around the 
peer review process, I am now convinced that the best way to 
move forward is through a competitive peer review process.
    Senator Specter. Well, Dr. Rostker, what are you referring 
to as having gone around the peer review process any lobbying? 
Dr. Haley says he has gone through the peer review process.
    Dr. Rostker. And, sir, the peer review process did not mark 
down Dr. Haley's results. When we funded Dr. Haley for $3 
million, I went back and asked the committee to identify those 
components of Dr. Haley's proposal, which they rated had 
scientific merit. And then we took it away from the competitive 
portion, having now identified the area that the peer reviews 
had scientific merit, and we funded all of the scientific 
merit. That is how we got to the $3 million.
    Senator Specter. Dr. Haley, did the peer review make 
findings? Is Dr. Rostker correct about that?
    Dr. Haley. Oh, I do not think that proposal was peer 
reviewed. We were contacted by the Office of Secretary of 
Defense above Dr. Rostker's office, invited to come up, present 
to the service chiefs and to the Secretary himself. And the 
Secretary put $3 million on the table there.
    Dr. Rostker. Not correct, sir.
    Dr. Haley. Dr. Rostker was not even there.
    Dr. Rostker. That is not correct. And by the way----
    Senator Specter. What is correct, Dr. Rostker?
    Dr. Rostker. What is correct is that Dr. Haley responded to 
a broad area announcement that was promulgated in 1995, 
promulgated by the U.S. Army Research and Medical Command. He 
asked for $12 million. The total amount that was available was 
$10 million. The American Institute of Biological Science, 
under contract to the Army, assembled a panel of independent, 
non-DOD scientists to peer review the scientific merit of the 
proposal submitted under 95-1 broad area announcement.
    The panel assigned a low scientific merit score to Dr. 
Haley's proposal overall and recommended only specific portions 
of the proposal met scientific merit for funding. The working 
group of the Persian Gulf Veterans Coordinating Board, which is 
the competitive selection authority, recommended against Dr. 
Haley's proposal based on its low overall scientific score. And 
its cost exceeded the total funds available for the 95-1 
solicitation.
    Following intense lobbying by Dr. Haley, DOD agreed to make 
limited funds, $3 million, available to fund only those 
specific portions of his proposal that were deemed to be 
scientifically meritorious by the independent peer review 
panel.
    Senator Specter. Dr. Sox, where do you suggest, after 
hearing this difference of opinion, to put it mildly, where do 
you suggest that the direction ought to be taken as to try to 
make a definitive answer. You testified that there were short-
term effects from the toxics you referred to. Where do you 
suggest we ought to go at this point?
    May the record show a grimace?
    Dr. Sox. Well, our committee regarded Dr. Haley's findings 
as interesting observations that were worthy of further study 
and replication in larger populations by other investigators. 
And my personal opinion is that that is the direction that we 
should go, through a peer review mechanism. The peer review 
mechanism for deciding who is going to get research money and 
who does not has served this country very well. And I am in 
agreement with Dr. Rostker that that is the right way to go.
    Mr. Perot. May I say something?
    Senator Specter. By all means. Mr. Perot, we were saving 
the best for last.
    Mr. Perot. I think you now clearly understand why this has 
gone on for 10 years and nothing has happened. It is this kind 
of talk right here. This is the captain of the stress team 
right here on my left.
    And that is his whole strategy.
    Dr. Rostker. Absolutely untrue. We looked at--I 
commissioned the Rand Corporation----
    Mr. Perot. Take it to court.
    Dr. Rostker. Good. Let us do that.
    We commissioned the Rand Corporation to do a whole series 
of reviews similar to what the IOM did, because those reviews 
were not available. One of the papers that Rand did was stress.
    And what Rand said was there are no markers for stress, 
that you could not draw a conclusion about stress, but that did 
not mean it existed. And we have never stressed stress. We have 
looked at pyridostigmine bromine. We have looked at pesticides. 
We have extensively looked, as you know, Mr. Chairman, at the 
use of chemicals on the battlefield.
    In part of my statement is an exchange between me and Dr. 
Haley about the possibility of chemicals on the battlefield, in 
which Dr. Haley declared himself not to be an expert on 
chemicals on the battlefield. In fact, he said he hardly ever 
talked about it. And you heard today that he claims to have 
definitive proof of chemicals on the battlefield. He has turned 
the whole logic train upside down.
    Senator Specter. Do you want to respond to that, Dr. Haley?
    Dr. Haley. Yes. That is strange, because I have not said 
anything about chemicals on the battlefield. What I have talked 
about is a genetic difference with a genetic enzyme whose only 
function in a toxicologic realm is protecting against nerve 
gas. In other words, there are different ways to skin a cat.
    And that is, it may well be that we will never have 
evidence, we will never amass enough evidence, to know who was 
exposed to what. But maybe the answer is not in their exposure 
histories, but it may be in their stars, you know, in their 
genes. And we can look in this genetic mechanism. If this 
finding is replicated, I think it is an inescapable conclusion 
that nerve gas was probably related to this problem.
    Senator Specter. Well, what I glean from what we have heard 
here today is that there is no real comprehensive, agreed-upon 
way to proceed. Dr. Rostker, you have the responsibility in the 
Department of Defense. The subcommittee would like you to give 
us your idea of a battle plan, to get a definitive answer and 
how you would go about it and how long it is going to take and 
what it is going to cost.
    And in the interim, Dr. Haley, we would encourage you 
pursue your line of inquiry. You are buttressed by what Dr. Sox 
has to say about the initial work which you have done.
    And, Dr. Sox, we would like you to look at the protocol. 
And before yielding to Senator Hutchison for the final, final 
word, Mr. Perot, what are your views at this point?
    Mr. Perot. Well, I think we ought to follow Churchill's 
words in World War II, action this day. We can talk about this 
forever. We can quibble about it forever. In the meantime, the 
men are suffering.
    Now what if, when this enlisted man was tangled in the 
rope, Ensign Johnson had gone through this thought pattern? 
Well, the guy would have lost--you know, while he was thinking 
about it, the guy would have died. Now, men are dying all the 
time. We have wasted most of our time on this bureaucratic 
rambling that goes on.
    There is, whether they want to admit it or not, a total 
bias to try to make this stress and keep everybody out of the 
arena that is trying to do anything except declare it stress. 
Stress, that just does not walk, even to a layman. You do not 
have to be an M.D. to figure out these patterns between the 
three of the wars and what have you. It does not fit. And a 
100-hour war is not a giant stress producer.
    More than anything else, we have to, in order to prepare 
and protect our people from the next war, we have to solve this 
problem. And as we solve the problem, one segment of it will 
be, how do you treat people. And we should move forward in a 
very orderly way.
    That is the reason I recommend, and I can summarize my 
recommendation, to turn it over to the National Institute of 
Health or CDC and have them run it.
    Senator Specter. Senator Hutchison, the last word----
    Mr. Perot. That is their business. They know how to do it.
    Senator Specter. Senator Hutchison, the last word.
    Senator Hutchison. Well, thank you, Mr. Chairman, for 
calling this hearing. I think it has been very informative. I 
am always reminded of the two different kinds of lawyers. There 
are the kinds of lawyers that tell you all the ways you cannot 
do something, and there are the kinds of lawyers who take the 
most complicated problem and tell you what you can do legally.
    I would like to see us tone down the rhetoric here. We have 
a few studies that seem to be definitive, the Rand study that 
says that really they did not find the stress-related causal 
connection. I think we should throw that out the window. So we 
have physical problems, and we now have a pretty good study 
that says it is not stress.
    So I think we need to take the next step. We have Dr. 
Haley's study, which I think certainly is a nugget from which 
to go. I think, Dr. Rostker, you were very right and correct 
and brave to go against all the scientists who had come for 10 
years with really nothing very definitive. And you said, OK, 
let us give this other approach a chance. You did that. And now 
I think you have something to hang onto. And let us do go--I 
believe that Dr. Haley would be very pleased to put his work to 
the test of other experts in the field.
    And I hope that the conflict between the two of you will 
not keep you from working together, because I think we have 
something to build on, maybe for the first time. And we 
certainly do not have any definitive results from this great 
other body of work, other than that stress is not a cause. So I 
think we have the nugget to work. And if we--I think we all 
have the same goal. And it is the goal that was stated by Mr. 
Perot. We have the responsibility to protect the next group 
that we send into the field.
    And if we could put the past behind us and say we have a 
nugget, let us take the next step to see where we go, and just 
hopefully we will be able to declare a Gulf war syndrome and 
focus on all the potential causal connections and the 
treatments and the protection in the future. And that is what I 
think all of us would like to do.
    And I thank all of you for the contributions you have made 
to hopefully starting that process.
    Senator Specter. Thank you very much, Captain Dyckman, Dr. 
Haley, Dr. Sox, Dr. Rostker.
