[Title]: A study of the relationships between angiotensin- converting enzyme gene, chymase gene polymorphisms, pharmacological treatment with ACE inhibitor and regression of left ventricular hypertrophy in essential hypertension patients treated with benazepril.
[Abstract]: BACKGROUND: About 15-37% of the adult population worldwide suffers from hypertension. Hypertension is responsible for one-third of all global deaths. Left ventricular hypertrophy (LVH) is one of the most important characteristics of hypertension target organ damage and is also an independent risk factor for cardiovascular events. Therefore, effective regression of LVH is a main aim of hypertension treatment and also an important public health concern. However, few studies of the regression of LVH have been reported. In particular, little is known about the relationship between the genotypes of angiotensin-converting enzyme (ACE) and chymase (CMA) genes, and the effectiveness of antihypertensive drugs in regression of LVH. AIM: The study investigated whether the insertion/deletion (I/D) polymorphism of ACE gene and the A/B polymorphism of the CMA gene are related to the regression of LVH in essential hypertension patients who were participants in a long-term trial of therapy with benazepril. SUBJECTS AND METHODS: Data from 157 patients was collected and used in the analysis. The genotypes of ACE and CMA genes were identified by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). Left ventricular mass (LVM) was measured by echocardiography, and left ventricular mass index (LVMI) was calculated. RESULTS: Blood pressure was markedly reduced and heart rate was unchanged by long-term treatment with benazepril. Regression of LVH was observed. The mean reduction in LVMI was 41.50+/-28.48 g m-2. Reduction of LVM, LVMI and percentage reduction of LVMI were more in the DD group than in the II and ID groups (P&lt;0.05). No significant difference in other indices was found in the different genotype groups of ACE (P&gt;0.05). No significant difference in all indices was found among the different genotype groups of CMA (P&gt;0.05). No interaction was found between the genotypes of ACE and CMA. CONCLUSION: Hypertension patients with the DD genotype are more likely to have regression of LVH when treated with benazepril than patients with other genotypes of ACE. No evidence was found to support an association between CMA genotype and regression of LVH in patients or to support the interaction between the two genes in regression of LVH.

[Title]: A randomized phase II study of paclitaxel with carboplatin +/- amifostine as first line treatment in advanced ovarian carcinoma.
[Abstract]: OBJECTIVE: Will amifostine (A) protect against chemotherapy-induced neuro- and myelotoxicity. PATIENTS AND METHODS: Ninety ovarian cancer patients were randomized to receive standard paclitaxel + carboplatin without (PC) or preceded by amifostine 740 mg/m(2) (PC + A). RESULTS: The mean baseline values of hemoglobin, leukocyte, and platelets were slightly lower in the amifostine group, but the mean percentual decrease of these parameters after each treatment cycle showed no difference between both arms. Symptoms of neurotoxicity remained absent in 40% PC vs. 49% PC + A cycles; sensory neurotoxicity grade I occurred in 45% vs. 48% and grade II in 12% PC vs. 2% of PC + A cycles (overall P &lt; 0.001). Nausea grade II was reported in 2% vs. 6% (P = 0.007) and vomiting grade II in 1% of PC vs. 8% PC + A cycles (P &lt; 0.001). Amifostine was temporarily interrupted in five patients due to hypotension, but no dose reductions were indicated. Quality of life questionnaires showed no difference in neurotoxicity scores between both study arms at treatment completion. The median progression-free survival was 16 vs. 22 months (n.s.) for PC and PC + A patients. In a pooled analysis of four randomized studies, amifostine diminished the risk of developing neurotoxicity grade II-III (Odds Ratio 0.3, 95% confidence interval 0.15-0.63, P &lt; 0.05), but had no effect on the risk for bone marrow toxicity. CONCLUSION: Amifostine shows only minor but significant activity in diminishing neurotoxicity without preventing paclitaxel + carboplatin-induced bone marrow toxicity.

[Title]: Effects of metoprolol and carvedilol on cause-specific mortality and morbidity in patients with chronic heart failure--COMET.
[Abstract]: BACKGROUND: Beta-blockers with different receptor bindings reduce mortality in patients with chronic heart failure. We compared the effects of the beta1-blocker metoprolol tartrate and the beta1-, beta2-, and alpha1-blocker carvedilol. METHODS: In a randomized double-blind design, 3029 patients with chronic congestive heart failure requiring diuretic therapy and with left ventricular dysfunction were randomized to treatment with carvedilol (n = 1511) or metoprolol tartrate (n = 1518) and titrated to target doses of 25 mg of carvedilol twice daily or 50 mg of metoprolol tartrate twice daily. The main outcome measures were total mortality and the combination of mortality or hospitalization for any cause. Secondary end points were cardiovascular death, combinations of morbidity and mortality, New York Heart Association class, worsening of heart failure, hospitalizations, and discontinuation of study therapy. RESULTS: A total of 512 and 600 patients in the carvedilol group and metoprolol group, respectively, died (hazard ratio [HR] 0.83, 95% CI 0.74-0.93, P = .0017). Cardiovascular death was reduced by carvedilol (HR 0.80, 95% CI 0.70-0.90, P = .0004). There were fewer sudden deaths and deaths caused by circulatory failure or by stroke in the carvedilol group. There was no difference in all-cause hospitalizations or in worsening heart failure between treatment groups. The incidence of fatal or nonfatal acute myocardial infarction was significantly lower in the carvedilol group (HR 0.71, 95% CI 0.52-0.97, P = .03). Discontinuations of study therapy were similar in the 2 groups. CONCLUSION: Compared with metoprolol tartrate, carvedilol reduced cardiovascular mortality, sudden death, death caused by circulatory failure, death caused by stroke, as well as fatal and nonfatal myocardial infarctions.

[Title]: Risperidone and haloperidol in first-episode psychosis: a long-term randomized trial.
[Abstract]: OBJECTIVE: The first episode of psychotic illness is a key intervention point. The initial experience with medication can affect willingness to accept treatment. Further, relapse prevention is a treatment cornerstone during the first years of illness because active psychotic illness may affect lifetime outcomes. Thus, initial treatment of active symptoms and subsequent relapse prevention are central goals of pharmacotherapy. This study compared long-term effectiveness of risperidone versus haloperidol in first-episode psychosis patients. METHOD: First-episode psychosis patients (N=555, mean age=25.4 years) participated in a double-blind, randomized, controlled flexible-dose trial that compared risperidone (mean modal dose=3.3 mg) and haloperidol (mean modal dose=2.9 mg). The median treatment length was 206 days (maximum=1,514). RESULTS: Positive and Negative Syndrome Scale scores and Clinical Global Impression ratings improved significantly relative to baseline, with no significant differences between groups. Three-quarters of the patients achieved initial clinical improvement, defined as &gt;20% reduction in total Positive and Negative Syndrome Scale score. However, among those who achieved clinical improvement, 42% of the risperidone group experienced a relapse compared with 55% of the haloperidol group. The median time to relapse was 466 days for risperidone-treated subjects and 205 days for those given haloperidol. These differences were statistically significant based on Kaplan-Meier survival analysis. Adverse effects distinguished the treatments: there were significantly more extrapyramidal signs and symptoms and adjunctive medication use in the haloperidol group and greater prolactin elevation in the risperidone group. There was less weight gain with haloperidol initially but no significant differences between groups at endpoint. CONCLUSIONS: Relatively low doses of antipsychotic drugs lead to significant symptom amelioration in the majority of first-episode psychosis patients. In the long term, risperidone prevents relapse in more patients and for a longer time and also induces less abnormal movements than haloperidol.

[Title]: [Efficacy of anti-thymocyte globulin and cyclosporin A combined therapy in aplastic anemia complicated with limited cutaneous systemic sclerosis].
[Abstract]: We reported here on a case of limited cutaneous systemic sclerosis (lcSSc) with aplastic anemia treated by anti-thymocyte globulin and cyclosporin A. The use of this therapy resulted not only in marrow recovery but also in resolution of the skin sclerosis. A 68 year-old woman was diagnosed as lcSSc accompanied by Hashimoto's thyroiditis and primary biliary cirrhosis. Treatment by D-penicillamine was started. After 11 months, She complained of nasal bleeding and subcutaneous bleeding. Her laboratory data revealed pancytopenia. White blood cell count, hemoglobin concentration and platelet count were decreased at 2300/microl, 8.2 g/dl, and 3000/microl respectively. Bone marrow was severely hypoplastic, suggesting aplastic anemia. The etiology of hypopastic marrow was considered to be D-penicillamine which had been frequently reported to cause hematopoietic cell suppression. We immediately started methylprednisolone pulse therapy combined with G-CSF and cyclosporin A, which showed little effectiveness. Next we tried the anti-thymocyte globulin therapy combined with G-CSF and cyclosporin A. Her blood cell counts gradually improved. After 4 months, she did not need the blood transfusion anymore. Furthermore, the sclerosis of her skin began to improve gradually, and the titer of anti-centromere antibody also decreased. Thus, anti-thymocyte globulin and cyclosporin A combined therapy can be considered among the therapies of systemic sclerosis.

[Title]: Pharmacokinetics of ximelagatran and relationship to clinical response in acute deep vein thrombosis.
[Abstract]: OBJECTIVE: Our objective was to characterize the pharmacokinetics of melagatran, the active form of the oral direct thrombin inhibitor ximelagatran, and the relationship between melagatran exposure and clinical outcome in patients with acute deep vein thrombosis. METHODS: A population pharmacokinetic analysis was performed on samples from patients with deep vein thrombosis participating in a randomized dose-finding study (THRombin Inhibitor in Venous thrombo-Embolism [THRIVE I]). Patients received fixed doses of oral ximelagatran (24, 36, 48, or 60 mg twice daily) for 12 to 16 days. Thrombus size was evaluated by venography before and after treatment. Exposure-response curves were characterized for the probability of regression, no change, and progression of the thrombus extension and of having a bleeding-related event, by use of logistic regression models. RESULTS: The pharmacokinetics of melagatran (1836 samples in 264 patients) was predictable, without significant time or dose dependencies. Clearance after oral administration (population mean, 27.3 L/h) was correlated with creatinine clearance (P < 10(-6)), and volume of distribution (population mean, 176 L) was correlated with body weight (P = 2 x 10(-5)). Gender, age, or smoking did not significantly influence melagatran pharmacokinetics after the influence of renal function and body weight was accounted for. Unexplained interpatient variability values in total plasma clearance and bioavailability were 19% and 21%, respectively. The median area under the plasma melagatran concentration versus time curve across all patients and dose levels was 3.22 h x micromol/L (5th-95th percentiles, 1.35-7.69). There was no significant relationship between area under the plasma concentration versus time curve and change in thrombus extension (P = .59) or bleeding-related events (P = .77), and the estimated exposure-response curves were relatively flat. CONCLUSIONS: The pharmacokinetics of melagatran in patients with acute deep vein thrombosis was predictable after oral ximelagatran administration. Shallow exposure-response curves for efficacy and bleeding indicate that there is no need for individualized dosing or therapeutic drug monitoring in the patient population studied.

[Title]: Cocaine abuse in schizophrenic patients treated with olanzapine versus haloperidol.
[Abstract]: Comorbid cocaine abuse adversely affects clinical outcomes in schizophrenia. Using a prospective, randomized, parallel group design (N = 24), we tested the hypothesis that patients with schizophrenia treated with olanzapine have reduced cocaine craving and abuse compared with those treated with haloperidol. In addition, we examined whether this differential effect correlated with reductions in extrapyramidal symptoms, positive and negative symptoms, and/or depression. There were no significant differences overall in proportions of positive drug screens between treatment groups; no differences in positive, negative, or depressive symptoms; and few differences between treatment conditions in extrapyramidal symptoms. However, craving for cocaine was rated significantly lower by patients treated with haloperidol compared with patients treated with olanzapine. Important study limitations include a small sample size and high attrition rates. Larger controlled studies are necessary to determine optimal antipsychotic therapy for patients with schizophrenia and comorbid cocaine abuse.

[Title]: Usefulness of famotidine in functional dyspepsia patient treatment: comparison among prokinetic, acid suppression and antianxiety therapies.
[Abstract]: BACKGROUND: The treatment of functional dyspepsia is controversial. AIM: The purpose of this paper is to clarify the initial effect of prokinetic, acid suppression and antianxiety treatment for functional dyspepsia patients. PATIENTS AND METHODS: Sixty-four functional dyspepsia patients without Helicobacter pylori infection were randomly assigned to 15 mg/day of mosapride, 40 mg/day of famotidine, or 30 mg/day of tandospirone during an 8-week treatment. Individual functional dyspepsia symptoms were evaluated with 4 cm visual analogue scale before and at 2, 4 and 8 weeks after treatment. RESULTS: Among 64 enrolled patients, 62 completed the study. Within 2 weeks, visual analogue scale score in the mosapride-treated group decreased from 2.29 +/-0.14 to 1.57 +/- 0.20; in the famotidine from 2.04 +/- 0.16 to 1.09 +/- 0.12 (mean +/- S.E.). Therefore, there were significant improvements of functional dyspepsia symptoms in mosapride- and famotidine-treated patients (P &lt;0.01). Furthermore, famotidine was significantly more effective than mosapride (P &lt; 0.05). On the contrary, visual analogue scale score in the tandospirone therapy was 2.23 +/- 0.20 and 2.13 +/- 0.22 before and at 2 weeks, respectively, without any significant improvement. CONCLUSIONS: A treatment regimen of famotidine at 40 mg/day had a significant favourable effect on the clinical outcome in functional dyspepsia patients.
