[Title]: Deleted in colorectal cancer protein expression as a possible predictor of response to adjuvant chemotherapy in colorectal cancer patients.
[Abstract]: PURPOSE: The deleted in colorectal cancer (DCC) gene predicts a poor outcome for patients with colorectal carcinoma. This study was designed to investigate whether the expression of the DCC protein also can predict response to adjuvant chemotherapy. METHODS: The expression of DCC was evaluated immunohistochemically in 74 paraffin-embedded tumor samples from patients with Stage II (n = 41) and Stage III (n = 33) colorectal carcinomas. Follow-up time was at least 60 (median, 64) months. Follow-up was at least five years for all patients who are alive. End points of the study were recurrence of disease and death. Forty-eight patients received adjuvant therapy of 5-fluorouracil + levamisole; 28 were not treated. RESULTS: Fifty percent of tumors were deleted in colorectal cancer-positive (DCC+). Proportion of survival and disease-free survival were higher in the DCC+ patients (83 percent) than in deleted in colorectal cancer-negative (DCC-; 54 percent). In the DCC+ group, adjuvant treatment was a strong positive predictive factor for survival and disease-free survival. All DCC+ patients who received adjuvant chemotherapy (CHEMO+) are alive with no evidence of disease, whereas without chemotherapy (CHEMO-) only 54 percent are alive ( P = 0.0001). When stratification was performed by stage, patients in Stage II who were DCC+/CHEMO+ had survival and disease-free survival of 100 percent, whereas in DCC+/CHEMO- survival rate was 75 percent and disease-free survival rate 62 percent ( P = 0.042). Patients in Stage III who were DCC+/ CHEMO+ had survival and disease-free survival of 100 percent, whereas in DCC+/CHEMO- both dropped to zero ( P = 0.0002). On the other hand, in the DCC- tumors, there was no statistical significant relationship between chemotherapy and survival or disease-free survival (DCC-/CHEMO- had 57 percent survival; DCC-/CHEMO+ had 52 percent survival). CONCLUSIONS: DCC is a prognostic factor for colorectal cancer. Positive expression of DCC identifies a subgroup of patients who respond favorably to adjuvant chemotherapy, which resulted in our cases, in 100 percent survival and disease-free survival rates. Without treatment, the survival rate of DCC+ patients dropped significantly. We suggest that DCC immunostaining should be performed routinely. All DCC+ patients should receive adjuvant chemotherapy. For DCC- tumors, a larger cohort of patients should be studied before definitive conclusions can be drawn; however, clinical trials of new drug combinations should focus on DCC- patients.

[Title]: Directly observed therapy for the management of HIV-infected patients in a methadone program.
[Abstract]: The objective of this prospective, observational clinical study was to evaluate the safety and efficacy of once-daily and twice-daily directly observed therapy (DOT) in human immunodeficiency virus (HIV)-infected patients undergoing methadone treatment. Methadone and highly active antiretroviral therapy (HAART) were dispensed daily as DOT, with patients in the twice-daily HAART group self-administering the second dose. Clinical and laboratory end points were monitored, along with the impact of ongoing cocaine use. We studied 54 patients coinfected with HIV and hepatitis C virus. At baseline, the median virus load was 111,000 copies/mL, and the median CD4+ cell count was 165 cells/mm3. After a median of 24 months, 17 of 29 patients in the once-daily HAART group and 18 of 25 in the twice-daily HAART group had virus loads of &lt;400 copies/mL, regardless of ongoing cocaine use. Thirty-two patients required methadone dose adjustment, which was managed without modification of HAART. Treatment-limiting hepatic toxicity was rare. A DOT program of coadministered methadone and HAART can be implemented with good results, even for patients who continue to use cocaine.

[Title]: [Clinical experience of landiolol for the treatment of intraoperative rapid atrial fibrillation].
[Abstract]: A 79-year-old woman with three vessel disease and mitral as well as tricuspid regurgitation underwent operation twice. Preoperatively she had atrial fibrillation and heart failure. The first operation was coronary artery bypass grafting (CABG), and the second was mediastinal dissection for mediastinitis one month after the CABG. In both operations she developed rapid atrial fibrillation and ventricular fibrillation, showing her cardiac irritablility. Both operations were performed under cardiopulmonary bypass and support. In the first operation digoxin and verapamil partly reduced heart rate of rapid atrial fibrillation from 140-170 to 110-140 beats x min-1, which made us use another drug, a short acting selective beta 1 blocker landiolol in the second operation. Landiolol successfully reduced the heart rate of rapid atrial fibrillation from 140-160 to 80-90 beats x min-1. This case demonstrates that landiolol can be safely used in a patient with heart failure due to rapid atrial fibrillation resistant to digoxin and verapamil.

[Title]: Zafirlukast for severe recurrent vulvovaginal candidiasis: an open label pilot study.
[Abstract]: BACKGROUND: Recurrent vulvovaginal candidiasis (VVC) has been linked to allergic disease, particularly allergic rhinitis. OBJECTIVE: A pilot study to assess the possible use of the leukotriene receptor antagonist zafirlukast as a treatment for recurrent VVC. METHODS: 20 women with six or more symptomatic attacks of VVC in the past year (at least four proved microbiologically). Clinical atopy determined by the International Study for Asthma and Allergies in Childhood (ISAAC) questionnaire assessed blindly. Monitoring by daily symptom diary and self taken vaginal swabs. Treatment with zafirlukast 20 mg twice daily for 24 weeks or until three microbiologically confirmed episodes of VVC. Response assessed by daily symptom diary and self taken vaginal swabs. Subjective response scales for improvement, side effects, and change in other allergic disease completed when stopping treatment. Semistructured telephone interview 1 year after stopping medication. RESULTS: 14 patients (70%) reported a subjective response on the improvement response scale. Six (30%) showed a complete response with no further symptomatic attacks of VVC or negative swabs when symptomatic. Seven (37%) remained symptom free 18 months after entering the study-that is, 12 months after stopping therapy. 11 (58%) remained symptom free for at least 3 months after stopping therapy. This does not include one patient who remained symptom free but continued on zafirlukast because of an improvement in her asthma. There was no clear relation between response and atopic status. Six of nine atopic subjective responders reported improvements in other allergic symptoms. Side effects were minimal; one seemed clearly attributable to the drug. CONCLUSION: Zafirlukast offers a potential new treatment for recurrent VVC that requires confirmation in controlled studies.

[Title]: Three year naturalistic outcome study of panic disorder patients treated with paroxetine.
[Abstract]: BACKGROUND: This naturalistic open label follow-up study had three objectives: 1) To observe the course of illness in Panic Disorder patients receiving long-term versus intermediate-term paroxetine treatment, 2) To compare the relapse rates and side-effect profile after long-term paroxetine treatment between patients with Panic Disorder and Panic Disorder with Agoraphobia, 3) To observe paroxetine's tolerability over a 24 month period. METHODS: 143 patients with panic disorder (PD), with or without agoraphobia, successfully finished a short-term (ie 12 week) trial of paroxetine treatment. All patients then continued to receive paroxetine maintenance therapy for a total of 12 months. At the end of this period, 72 of the patients chose to discontinue paroxetine pharmacotherapy and agreed to be monitored throughout a one year discontinuation follow-up phase. The remaining 71 patients continued on paroxetine for an additional 12 months and then were monitored, as in the first group, for another year while medication-free. The primary limitation of our study is that the subgroups of patients receiving 12 versus 24 months of maintenance paroxetine therapy were selected according to individual patient preference and therefore were not assigned in a randomized manner. RESULTS: Only 21 of 143 patients (14%) relapsed during the one year medication discontinuation follow-up phase. There were no significant differences in relapse rates between the patients who received intermediate-term (up to 12 months) paroxetine and those who chose the long-term course (24 month paroxetine treatment). 43 patients (30.1%) reported sexual dysfunction. The patients exhibited an average weight gain of 5.06 kg. All patients who eventually relapsed demonstrated significantly greater weight increase (7.3 kg) during the treatment phase. CONCLUSIONS: The extension of paroxetine maintenance treatment from 12 to 24 months did not seem to further decrease the risk of relapse after medication discontinuation. Twenty-four month paroxetine treatment is accompanied by sexual side effects and weight gain similar to those observed in twelve month treatment.

[Title]: Higher pentamidine levels in AIDS patients with hypoglycemia and azotemia during treatment of Pneumocystis carinii pneumonia.
[Abstract]: Trimethoprim-sulfamethoxazole (TMP-SMZ) and pentamidine are both licensed for the treatment of Pneumocystis carinii pneumonia (PCP). However, their use is associated with various adverse side effects. In this prospective study, 26 AIDS patients with 32 episodes of PCP were treated with pentamidine (4 mg/kg/d). Each patient was treated for 12 to 21 days, depending on the rapidity of onset of the clinical response. During the 32 PCP episodes, hypoglycemia occurred in 16 instances, azotemia in 12, liver toxicity in 10, and leukopenia in 8. The occurrence of thrombopenia, leukopenia, and liver toxicity was not related to age, pentamidine levels, or other complications. However, patients who had hypoglycemia during pentamidine treatment had higher serum pentamidine levels than patients who did not have hypoglycemia (107 +/- 40 versus 70 +/- 26 ng/ml, p less than 0.004). In addition, we observed that patients with azotemia showed higher pentamidine levels during treatment (120 +/- 35 versus 64 +/- 22 ng/ml, p less than 0.001). In fact, 100% (11/11) of patients with serum pentamidine concentration greater than 100 ng/ml had fasting hypoglycemia and/or azotemia, while 33% (7/21) of those with pentamidine levels less than 100 ng/ml had these side effects (p less than 0.001). The relative risk of these complications with pentamidine levels greater than 100 ng/ml was 3 (95% confidence interval, 1.6 to 5.5). Fine-tuning the dose of pentamidine may eventually prove useful to avoid toxicity and optimize therapy.

[Title]: Treatment of acute heart failure in an infant after cardiac surgery using levosimendan.
[Abstract]: An infant, 2 months old, underwent cardiac surgery because of congenital heart defects and pulmonary hypertension. Surgery was performed in hypothermia and cardiac standstill. On the second day after surgery the infant had to be resuscitated due to a combination of acute left-ventricular failure, pulmonary vascular hypertension and a slight right-to-left-shunt. A breakthrough in the treatment was achieved by using levosimendan to improve left-ventricular function and to decrease vascular resistance.

[Title]: Arsenic trioxide and thalidomide combination produces multi-lineage hematological responses in myelodysplastic syndromes patients, particularly in those with high pre-therapy EVI1 expression.
[Abstract]: Twenty-eight myelodysplastic syndromes (MDS) patients were treated with arsenic trioxide (ATO) and thalidomide. Seven patients responded including one complete hematologic and cytogenetic response and one with regression in spleen size. Two trilineage responses were seen in patients with inv(3)(q21q26.2). Three of five patients who had high pre-therapy EVI1 levels showed unexpectedly good responses while two died early in the first cycle. In vitro studies using 32Dcl3 cells forced to express EVI1 confirmed increased sensitivity of these cells to ATO. Both low/high risk MDS may benefit significantly from therapy with ATO/thalidomide, and those with high pre-therapy EVI1 expression may be uniquely sensitive.

[Title]: Sex differences in cocaine-dependent individuals' response to disulfiram treatment.
[Abstract]: The objective of this study is to evaluate differential response to disulfiram treatment of cocaine dependence by sex. Sex by treatment interactions from two pooled randomized clinical trials involving 191 cocaine-dependent subjects (36% female) were evaluated. Primary outcomes were days of abstinence and percentage of drug-free urine specimens. Significant sex by treatment interactions were found, where men treated with disulfiram had better outcomes than those who were not. Women had an intermediate outcome regardless of whether they received disulfiram. Sex differences in response to disulfiram treatment have important clinical and theoretical implications. Reasons for this apparent sex-based response are not clear, but possible mechanisms worthy of greater study include differences in alcohol use by sex as well as differences in dopamine-mediated responses to cocaine and disulfiram.

[Title]: Equivalence of indapamide SR and enalapril on microalbuminuria reduction in hypertensive patients with type 2 diabetes: the NESTOR Study.
[Abstract]: OBJECTIVES: To test whether microalbuminuria in patients with type 2 diabetes and hypertension is primarily dependent on the severity of hypertension, and to compare the effectiveness of two antihypertensive drugs with opposite effects on the renin-angiotensin system [the diuretic, indapamide sustained release (SR), and an angiotensin-converting enzyme inhibitor, enalapril] in reducing microalbuminuria. DESIGN: A multinational, multicentre, controlled, double-blind, double-dummy, randomized, two-parallel-groups study over 1 year. METHODS: After a 4-week placebo run-in period, 570 patients (ages 60.0 +/- 9.9 years, 64% men) with type 2 diabetes, essential hypertension [systolic blood pressure (SBP) 140-180 mmHg, and diastolic blood pressure (DBP) &lt; 110 mmHg], and persistent microalbuminuria (20-200 microg/min) were allocated randomly to groups to receive indapamide SR 1.5 mg (n = 284) or enalapril 10 mg (n = 286) once a day. Amlodipine, atenolol, or both were added, if necessary, to achieve the target blood pressure of 140/85 mmHg. RESULTS: There was a significant reduction in the urinary albumin : creatinine ratio. Mean reductions were 35% [95% confidence interval (CI) 24 to 43] and 39% (95% CI 30 to 47%) in the indapamide SR and enalapril groups, respectively. Equivalence was demonstrated between the two groups [1.08 (95% CI 0.89 to 1.31%); P = 0.01]. The reductions in mean arterial pressure (MAP) were 16.6 +/- 9.0 mmHg for the indapamide SR group and 15.0 +/- 9.1 mmHg for the enalapril group (NS); the reduction in SBP was significantly greater (P = 0.0245 ) with indapamide SR. More than 50% of patients in each group required additional antihypertensive therapy, with no differences between groups. Both treatments were well tolerated. CONCLUSIONS: Indapamide-SR-based therapy is equivalent to enalapril-based therapy in reducing microalbuminuria with effective blood pressure reduction in patients with hypertension and type 2 diabetes.
