High grade malignant lymphoma with clinical characteristics and immunophenotype of natural killer cells
Authors: Schleiffenbaum Boris , Rüegg R. , Zimmermann D. , Fehr JÖRg
Published: February 2007

The malignant proliferation of natural killer (NK) cells which are morphologically characterized as large granular lymphocytes (LGL) is a well known clinical entity which was named after its morphological appearance as LGL‐leukemia/lymphoma. Similar to non‐malignant NK‐cells, these tumors can be divided into those which express the CD3‐T‐cell receptor complex and those which do not. The CD3‐positive type of LGL‐leukemia is immunophenotypologically characterized by the expression of CD16, and variably CD 56 and CD 57, and generally follows a more indolent course. In contrast, malignant proliferations of CD3‐negative LGL express either CD16 or CD 56, and only occasionally CD 57 on their cell surface. Clinically, CD3‐negative NK‐lymphomas tend to progress rapidly. We report here the case of a high grade malignant lymphoma which was characterized by an immunophenotype typical for CD3‐negative NK‐cells (CD2+, CD3−, CD16+, CD56(+), CD57−). The disease proved to be rapidly fatal despite aggressive chemotherapy. Interestingly, the patient suffered from a high turn over pancytopenia, which also characterizes NK‐cell leukemias/lymphomas of the LGL‐type. However, our patient's lymphatic cells appeared highly immature, and cytoplasmic granules, characteristic for LGL‐cells, could not be discerned either microscopically or electronmicroscopically. Furthermore, the malignant lymphatic population had the T‐cell receptor α‐chain rearranged. We therefore concluded that our patient might have suffered from a malignant proliferation of a putative precursor cell intermediate between T‐cells and NK‐cells. © 1995 Wiley‐Liss, Inc.
Anabolic‐Androgenic steroid abuse in weight lifters: Evidence for activation of the hemostatic system
Authors: Ferenchick Gary S. , Hirokawa Shinchirou , Mammen Eberhard F. , Schwartz Kenneth A.
Published: February 2007

Anabolic‐androgenic steroid abuse has recently been linked with acute vascular events in athletes. To date, the relationship between steroid abuse and the potential for cardiovascular disease has been considered almost exclusively in terms of lipid metabolism. However, recent reports of thrombosis in androgen abusing athletes with no evidence of atherosclerosis suggests the hypothesis that thrombosis risk in such athletes could be mediated through androgen induced abnormalities of coagulation.

To determine if anabolic‐androgenic steroid abuse in weight lifters is associated with an activation of the hemostatic system we studied forty‐nine weight lifters recruited through advertisements. History of androgen use or abstinence was confirmed via urine assays. Plasma was assayed for clotting and fibrinolytic activity by measuring thrombin/ antithrombin complexes (TAT), prothrombin fragment 1 + 2 (F1 + 2), and D‐dimers (D‐di); markers of the endothelial based fibrinolytic components were assayed by measuring tissue plasminogen activator antigen (t‐PA Ag) and its inhibitor (PAI‐1); finally, the activity of antithrombin III, protein C, and protein S were measured.

Abnormally high concentrations of TAT complexes were noted in 16% of our confirmed steroid using weight lifters compared to 6% of our confirmed nonusers (P = .01). Steroid users also demonstrated abnormally high concentrations of F1 + 2 and D‐dimers when compared to nonusers (44 vs. 24%, P < .001, and 9 vs. 0%, respectively). Non‐steriod users were more likely to have elevated levels of t‐PA Ag and PAI‐1 than our steroid using weight lifters (both P < .001). The activities of antithrombin III and protein S were more likely to be higher in users compared to nonusers (22 vs. 6%, P = .005; 19 vs. 0%, respectively).

Some anabolic‐androgenic steroid using weight lifters have an accelerated activation of their hemostatic system as evidenced by increased generation of both thrombin and plasmin. These changes could reflect a thrombotic diathesis that may contribute to vascular occlusion reported in young athletes using these drugs. The predictive value of these coagulation abnormalities in terms of risk of thrombosis to individual steroid using weight lifters or the population as a whole remains to be studied. © 1995 Wiley‐Liss, Inc.
Platelet von willebrand factor abnormalities in myeloproliferative syndromes
Authors: Castaman Giancarlo , Lattuada Antonella , Ruggeri Marco , Tosetto Alberto , Mannucci Pier Mannuccio , Rodeghiero Francesco
Published: February 2007

Plasma and platelet von Willebrand factor (vWF) measurements, multimeric pattern and subunit composition of plasma vWF were obtained in 29 consecutive patients with chronic myeloproliferative syndromes. In the 8 patients with chronic myelogenous leukemia (CML), plasma vWF was significantly higher than in the 11 patients with essential thrombocythemia (ET) and in the 10 patients with polycythemia Vera (PV). The RiCof/ vWF:Ag ratio was low in all these groups of patients (mean 0.64 = 0.1, 0.66 = 0.2; and 0.61 = 0.2; normal 0.97 = 0.2). Bleeding time was prolonged (>7.5 min) in 1/8 CML patients, 1/10 with PV, and 3/11 with ET. Plasma vWF multimers showed a minor loss of the largest multimers in 3/8 patients with CML, 4/10 with PV, and a more severe reduction in 9/11 ET patients. The latter pattern correlated with an abnormal proteolysis of vWF, expressed by a major increase of the 140‐Kd fragment and decrease of the intact 225‐Kd subunit in ET patients, whereas the 176‐Kd fragment was significantly increased in all the subgroups of patients. Platelet vWF was significantly higher in CML patients in comparison to ET and normal controls. However, minor losses of the larger multimers were evident in all the subsets of patients. In ET patients also the intermediate forms were lacking in platelets, accompanied by a significant decrease of platelet RiCof. This abnormality was significantly correlated with the occurrence of bleeding symptoms in PV and ET patients (P = 0.007; Fisher's exact test). In conclusion, plasma and platelet vWF abnormalities are common findings in myeloproliferative syndromes and are more severe in ET. The more pronounced platelet vWF abnormalities in ET may reflect the more frequent bleeding symptoms observed in this disorder. © 1995 wiley‐Liss, Inc.
Late appearance of the Philadelphia chromosome with monosomy 7 in a patient with de novo AML with trilineage myelodysplasia
Authors: Matsue Kosei , Miyamoto Toshihiro , Ito Mami , Tsukuda Koji
Published: February 2007

We report here a patient with de novo acute myelocytic leukemia with trilineage myelodysplasia (AML/TMDS) in whom cytogenetic analysis was normal at diagnosis and in whom Philadelphia chromosome (Ph1) with monosomy 7 emerged at the terminal stage of the disease. Reverse transcription polymerse chain reaction (RT‐PCTR) on the Ph1 positive specimen detected the mRNA encoding p190bcr/ab1 was not detected at diagnosis and or at relapse. These observations support the hypothesis that late‐appearing Phl and monosomy 7 might be the result of clonal evolution during the course of leukemia, and p190bcr/abl might play a role in the terminal transformation or progression of leukemia. © 1995 Wiley‐Liss, Inc.

Authors: Waye John S. , Eng Barry , Patterson Margaret , Wasi Parveen , Chui David H. K. , Francombe William H. , Sher Graham D. , Olivieri Nancy F.
Published: February 2007

Among individuals of Mediterranean or Middle Eastern descent, the IVS‐I‐6 (T→C) mutation is one of the most common causes of β‐thalassemia. In this report, we describe the clinical phenotypes of a group of β‐thalassemia patients who are compound heterozygotes for the relatively mild IVS‐I‐6 (T→C) β‐thalassemia mutation and more severe β+‐ or β°‐thalassemia mutations. Although most of these patients are transfusion‐dependent, the requirement for regular transfusions generally occurred late in childhood. A correlation between concomitant α‐thalassemia and a mild transfusion‐independent phenotype is not apparent, indicating the involvement of other ameliorating determinants.
Thrombotic thrombocytopenic purpura/hemolytic uremic syndrome secondary to pancreatitis
Authors: Silva Victor A.
Published: February 2007

Pancreatitis is a rare (∼2.0%) complication of thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS). The opposite finding has rarely been reported. We present a case of an 18 years old obese male with alcohol associated pancreatitis (amylase 840 IU/L) who three days after onset, as the pancreatitis subsided (amylase 341 U/L), developed TTP/HUS. The TTP/HUS was marked by oliguria and severe renal failure (creatinine 1,326 μmol/L), was treated with daily plasma exchanges, obtained a complete response, and recovered renal function (creatinine 115 μmol/L). Similarly, in six of seven other cases from the medical literature the TTP/HUS occurred within 2–3 days of the onset of pancreatitis.
EDTA‐dependent pseudothrombocytopenia: A clinical and epidemiological study of 112 cases, with 10‐year follow‐up
Authors: Bizzaro Nicola
Published: February 2007

In the past 10 years, we have observed 112 cases of EDTA‐dependent pseudothrombocytopenia (PTCP) due to in vitro platelet clumping at room temperature. 93 patients had antiplatelet antibodies (48 IgM, 30 IgG, 3 IgA, and 12 had two different isotypes concomitantly). In 20% of patients, the presence of IgM antibodies characteristically accompanied platelet agglutination also at 37°C, and in citrated blood. The phenomenon was not age or sex related, nor was it associated with any particular pathology or use of specific drugs, and was present in both healthy subjects and patients with various diseases.

Flow cytofluorimetric analysis of CD5‐positive B cells, which are responsible for autoantibody production, did not demonstrate any changes in the percentage and absolute number of this lymphocyte subset.

Average follow‐up was 5 years (6 months‐10 years); however, previous clinical records disclosed that PTCP was present for more than 15 years in four cases, and more than 20 years in three others, with no clinical manifestation of disease.

This study confirms that EDTA‐dependent PTCP is a phenomenon related to the presence of natural autoantibodies with antiplatelet activity, devoid of pathological significance. Its clinical interest resides in the need for its prompt and certain recognition in order to avoid unnecessary examinations and therapeutic interventions.

The best and most rapid technique for obtaining accurate platelet counts in PTCP subjects is to collect and examine EDTA blood at 37°C; however, clumping will still be present in about 20% of these cases, and even in citrated blood. To obviate this phenomenon, blood should be collected in ammonium oxalate, and platelets counted in a Burker chamber.

Published: February 2007

We report three patients with pulmonary disorders associated with myelodysplastic syndromes (MDS). All three patients had symptoms of pyrexia and respiratory discomfort. One patient had pulmonary eosinophilia with bilateral pleural effusion, one had interstitial pneumonia, and one had bilateral pleural effusion caused by systemic vasculitis. Elevated C‐reactive protein (CRP) levels, polyclonal hypergammaglobulinemia, and morphological abnormalities in peripheral blood were observed in all three patients. The bone marrow of these patients revealed trilineage dysplasia and eosinophilia. Cytogenetic analysis showed [46,XY,‐7,+der(1q;7p)]. Antibiotic treatment was not effective. However, improvement was dramatic after corticosteroid treatment; CRP levels were reduced and the hypergammaglobulinemia was improved. These cases suggest that MDS with [‐7,+der(1q;7p)] may be correlated with bone marrow eosinophilia and that an immunologic abnormality may be involved in the pulmonary disorders.
Sustained activation of blood coagulation in patients with cerebral thrombosis
Authors: Seki Yoshinobu , Takahashi Hoyu , Wada Ken , Shibata Akira
Published: February 2007

Recent progress in the measurements of the hemostatic markers enables us to assess the detailed profiles of hemostatic activation in various diseases. To evaluate the degree of hemostatic system activation in patients with cerebral thrombosis, detailed coagulation studies were performed in 28 patients with acute‐phase cerebral thrombosis and in 36 with chronic‐phase cerebral thrombosis, together with 6 with chronic‐phase cerebral hemorrhage and 37 age‐matched healthy volunteers. In both acute‐phase and chronic‐phase cerebral thrombosis, plasma levels of thrombin‐antithrombin III complex, plasmin‐α2‐plasmin inhibitor complex and D‐dimer were significantly higher, and antithrombin III and protein C were significantly lower than those in the normal group. Plasma fibrinogen concentration was significantly higher in chronic‐phase cerebral thrombosis than that in chronic‐phase cerebral hemorrhage. No significant difference was found in these variables between acute‐phase and chronic‐phase cerebral thrombosis. In addition, there was no difference in these parameters between chronic phase cerebral hemorrhage and normal subjects. These findings indicate that a sustained activation of coagulation and fibrinolysis is present in cerebral thrombosis, and it might contribute to the pathogenesis of cerebral thrombosis.
Triosephosphate isomerase deficiency: Repetitive occurrence of point mutation in amino acid 104 in multiple apparently unrelated families
Authors: Schneider Arthur , Westwood Beryl , Yim Catherine , Prchal Josef , Berkow Roger , Labotka Richard , Warrier Rajasekharan , Beutler Ernest
Published: February 2007

The molecular basis of triosephosphate isomerase (TPI) deficiency was studied in 3 patients from three separate families. In all 3 patients, genomic DNA directly sequenced after amplification by the polymerase chain reaction exhibited the point mutation TPI315C amino acid 104 Glu→Asp. Although other mutations known to cause TPI deficiency have been restricted to single families, the amino acid 104 defect has now been described in nine apparently unrelated families throughout the world and is clearly the most frequently occurring form of the disorder. The basis of the repetitive occurrence of this mutation remains unexplained.

Published: February 2007

Hereditary factor VII deficiency is a rare autosomal recessive condition, usually associated with normal or reduced levels of a functionally defective molecule. The available means of treating this condition in North America presents serious health risks to the patient. Transfusion with fresh frozen plasma carries a risk of volume overload and a significant risk for viral transmission. Sustained prothrombin complex therapy is associated with a high risk for thrombogenic complications. This communication describes the use of Factor VII Concentrate (Human) Immuno, Vapor Heated—an intermediate purity factor VII concentrate from Immuno A.G.—for the treatment of 13 patients with factor VII deficiency. Treatment regimens described include those for long‐term prophylaxis (three children), acute hemorrhages (two children, one adult), peripartum prophylaxis (one patient), and surgical coverage (two children, four adults). Prophylaxis and therapy were successful in all cases, the medication was well‐tolerated, and there were no complications. In the three cases of long‐term prophylaxis in children, doses of 10‐50 lU/kg were given one to three times a week; one patient has undergone long‐term prophylaxis for approximately 8 years, one patient for 1 year, and one patient for 1 1/2 years. Three cases in which Factor VII Concentrate was principally used for treatment of acute episodes of bleeding are described. One infant received Factor VII Concentrate on about 50 occasions for treatment of mucosal bleeding; a correction to 40–100% resulted in cessation of bleeding within 15 min in all cases. For treatment of an episode of intracranial bleeding, an 8‐year‐old boy received a dose of 37 IU/kg Factor VII Concentrate every 6 hr for peak factor VII levels of approximately 100% and troughs as low as 4% over the 11‐day treatment period. A 37‐year‐old adult male with intracranial bleeding received alternating doses of 16 IU/kg and 8 IU/kg every 6 hr for 10 days with peak factor VII levels in the upper thirties (%). The peak favor VII level during surgical coverage with Factor VII Concentrate (neurosurgery, open reduction of ankle bones, dental surgery, pituitary adenoma surgery, closed liver biopsy) was approximately 100% in all cases, with trough levels ranging from 8 to 65% over treatment periods of 24 hr to 16 days using treatment intervals of 6–12 hr.

Published: February 2007

Background

Data on prevalence of lung diseases due to inhalation of carbonaceous materials other than mineral coal is very limited.

Methods

We present three cases of wood charcoal pneumoconiosis, two due to activated carbon, and one from wood charcoal artisan handling. To our knowledge, no clinical cases of wood charcoal pneumoconiosis, from artisan handling has been published so far.

Clinical Cases

The three cases had their X rays classified by two B‐readers as p/q round opacities with profusion ranging from 2/2 to 3/3. HRCT of two of them showed a diffuse centrilobular ground glass nodular pattern with subpleural small areas of consolidations. Transbronchial biopsies showed deposition of black pigment in the bronchiolar interstice similar to the histological appearance of simple coal workers pneumoconiosis, with no signs of fibrosis. Spirometry showed no abnormalities in the three cases.

Conclusions

The authors point out to a probably underestimated respiratory occupational risk related to wood charcoal manipulation, which must be addressed mostly in developing countries, where deficient workplace conditions can lead to exposure above limit levels.

Estimation of the number of working hours critical for the development of mental and physical fatigue symptoms in Japanese male workers—application of benchmark dose method
Authors: Suwazono Yasushi , Nagashima Shouji , Okubo Yasushi , Uetani Mirei , Kobayashi Etsuko , Kido Teruhiko , Nogawa Koji
Published: February 2007

Background

To clarify the influence of working hours on subjective fatigue symptoms and obtain the critical dose (number of hours) to determine the number of permissible working hours, we calculated the benchmark dose (BMD) and the 95% lower confidence limit on BMD (BMDL) of working hours for subjective mental and fatigue symptoms using multivariate logistic regression.

Methods

Self‐administered questionnaires were distributed to all 843 male daytime workers aged ≤60 years in a single chemical factory, and 715 provided complete replies. The odds ratios of daily working hours were determined using positive findings of the Self‐rating Depression Scale and 8 subscales of the Cumulative Fatigue Symptom Index as dependent variables, and other potential covariates as independent variables. Using significant parameters for the working hours and those for other covariates, the BMD and BMDL (BMD/BMDL) values were calculated for corresponding dependent variables. The benchmark response (BMR) was set at 5% or 10%.

Results

The BMDL with a BMR of 5% was shown to be 9.6–11.6 hr per day, which corresponds to 48–58 working hours per week and 36–78 overtime hours per month.

Conclusions

These results suggest that special attention should be paid to the workers whose working hours exceed these BMD/BMDL values. Am. J. Ind. Med. 50: 173–182, 2007. © 2007 Wiley‐Liss, Inc.

Frequency of single nucleotide polymorphisms of CYP2D6 in the Czech population
Authors: Buzková Helena , Pechandová Kristina , Slanař Ondřej , Perlík František
Published: February 2007

CYP2D6 is a member of cytochrome P450 enzymes that metabolise over 25% of commonly used drugs. Genetic polymorphisms can cause insufficient drug efficacy at usually administered doses or can be the cause of adverse drug reaction. CYP2D6 genotyping can be used to predict CYP2D6 phenotype and thereby explain some abnormalities in drug response and thus optimize pharmacotherapy. The aim of this study was to investigate the frequency of functionally important variant alleles of the CYP2D6 gene throughout the Czech population to predict the prevalence of ultra‐rapid and poor metabolizer phenotypes. The DNA of 223 unrelated, healthy volunteers was analysed to detect the presence of CYP2D6*6, *5, *4, *3 and gene duplication. The variant allele frequencies in our population were 0.22%, 3.14%, 22.87%, 1.12% and 3.14% for CYP2D6*6, CYP2D6*5, CYP2D6*4, CYP2D6*3 and CYP2D6*MxN, respectively. Fifteen subjects carried two variant alleles leading to predicted poor type of metabolism, 84 subjects were heterozygous extensive metabolizers (het‐EM). The full‐text contains detailed comparison with European white populations. The distribution of variant alleles complies with the Hardy–Weinberg equilibrium. The frequencies of functional variant alleles of CYP2D6 in Czech population are in concordance with other Caucasian populations. Copyright © 2007 John Wiley & Sons, Ltd.
