[Title]: Fluticasone propionate versus zafirlukast: effect in patients previously receiving inhaled corticosteroid therapy.
[Abstract]: BACKGROUND: The use of inhaled corticosteroids compared with leukotriene modifying drugs in the treatment of persistent asthma has not been extensively studied. OBJECTIVE: To compare the efficacy and safety of a low dose of fluticasone propionate (FP) and zafirlukast in patients previously maintained on inhaled corticosteroids. METHODS: Patients (> or = 12 years old; FEV1 = 60% to 85% of predicted) with persistent asthma who were previously treated with low doses of triamcinolone acetonide (TAA) 400 to 800 microg/day or beclomethasone dipropionate (BDP) 168 to 336 microg/day were randomized to treatment with FP aerosol 88 microg BID (FP, n = 221) or zafirlukast 20 mg BID (n = 216) over 6 weeks. RESULTS: Treatment with FP significantly increased the mean change at endpoint (the last post-baseline observation) in FEV1 (0.22 L versus 0.03 L, P < .001), morning PEF (17.8 versus 3.1 L/min, P = .004), evening PEF (16.7 versus 2.6 L/min, P = .002), the percentage of symptom-free days (16.2 versus 7.1%, P = .007), and the percentage of rescue-free days (23.4 versus 9.3%, P < .001), and significantly decreased rescue albuterol use (-0.66 puffs/day versus an increase of 0.27 puffs/day, P < .001) and combined symptom scores (-0.13 versus an increase of 0.08, P < .001) compared with zafirlukast. Treatment with FP maintained the percentage of awakening-free nights (-1.0 +/- 1.0); in contrast, treatment with zafirlukast reduced the percentage of awakening-free nights (-9.0 +/- 1.6, P < .001). A clinically meaningful difference (change of > or = 0.5; P < .001) was observed between FP and zafirlukast in the Asthma Quality of Life Questionnaire (AQLQ) global score and for each domain score except activity limitation (change of 0.3, P < .001). Significantly more patients in the zafirlukast group experienced an asthma exacerbation (n = 14) compared with FP-treated patients (n = 5, P = .035). Patients in the zafirlukast group were significantly more likely to be withdrawn due to lack of efficacy (P < .001). CONCLUSION: Switching patients from low doses of inhaled corticosteroids to a lower total microgram dose of FP improves pulmonary function, asthma symptoms, and quality of life, while switching to the leukotriene receptor antagonist zafirlukast may result in worsening of asthma control. This was indicated by the significant number of zafirlukast-treated patients who were dropped from the study due to lack of efficacy within 6 weeks of discontinuing inhaled corticosteroids.

[Title]: Cilostazol in secondary prevention of stroke: impact of the Cilostazol Stroke Prevention Study.
[Abstract]: According to recent epidemiological data in Japan, stroke affects roughly 5.3 males and 3.9 females per 1000 person-years and is the third leading cause of mortality. At present, management strategies for secondary prevention of stroke include aggressive treatment of cardiovascular risk factors (i.e., hypertension, smoking cessation, etc.). Antiplatelet drugs in Japan, namely aspirin and cilostazol, are utilized regularly for the prevention of secondary stroke. While aspirin is beneficial for a wide range of cardiovascular endpoints, including total and ischemic strokes, it is also associated with significantly increased risks for hemorrhagic infarction. Cilostazol, by contrast, has been shown to significantly reduce the risk of recurrent strokes without affecting the occurrence of intracranial hemorrhage. In the Cilostazol Stroke Prevention Study, a randomized double-blind, placebo-controlled trial involving more than 1000 Japanese patients, cilostazol was found to reduce the risk of secondary stroke by 41.7% compared with placebo, a statistically significant reduction (P = 0.015). The greatest risk reduction (43.4% in cilostazol versus placebo, P = 0.0373) was found in patients who initially had a lacunar infarction, suggesting that cilostazol has a specific effect against small-vessel disease. In addition, cilostazol achieved significant risk reductions on a number of combined endpoints (e.g., cerebral infarction, intracranial hemorrhage, myocardial infarction, or vascular death), and was associated with benefits in intent-to-treat analyses. These findings indicate that cilostazol may have a role as a vascular neuroprotectant, but the clinical implications are limited by the fact that patients were randomized to placebo instead of aspirin, which is the standard of care.

[Title]: Tamoxifen for the prevention of breast cancer: current status of the National Surgical Adjuvant Breast and Bowel Project P-1 study.
[Abstract]: BACKGROUND: Initial findings from the National Surgical Adjuvant Breast and Bowel Project Breast Cancer Prevention Trial (P-1) demonstrated that tamoxifen reduced the risk of estrogen receptor-positive tumors and osteoporotic fractures in women at increased risk for breast cancer. Side effects of varying clinical significance were observed. The trial was unblinded because of the positive results, and follow-up continued. This report updates our initial findings. METHODS: Women (n = 13,388) were randomly assigned to receive placebo or tamoxifen for 5 years. Rates of breast cancer and other events were compared by the use of risk ratios (RRs) and 95% confidence intervals (CIs). Estimates of the net benefit from 5 years of tamoxifen therapy were compared by age, race, and categories of predicted breast cancer risk. Statistical tests were two-sided. RESULTS: After 7 years of follow-up, the cumulative rate of invasive breast cancer was reduced from 42.5 per 1000 women in the placebo group to 24.8 per 1000 women in the tamoxifen group (RR = 0.57, 95% CI = 0.46 to 0.70) and the cumulative rate of noninvasive breast cancer was reduced from 15.8 per 1000 women in the placebo group to 10.2 per 1000 women in the tamoxifen group (RR = 0.63, 95% CI = 0.45 to 0.89). These reductions were similar to those seen in the initial report. Tamoxifen led to a 32% reduction in osteoporotic fractures (RR = 0.68, 95% CI = 0.51 to 0.92). Relative risks of stroke, deep-vein thrombosis, and cataracts (which increased with tamoxifen) and of ischemic heart disease and death (which were not changed with tamoxifen) were also similar to those initially reported. Risks of pulmonary embolism were approximately 11% lower than in the original report, and risks of endometrial cancer were about 29% higher, but these differences were not statistically significant. The net benefit achieved with tamoxifen varied according to age, race, and level of breast cancer risk. CONCLUSIONS: Despite the potential bias caused by the unblinding of the P-1 trial, the magnitudes of all beneficial and undesirable treatment effects of tamoxifen were similar to those initially reported, with notable reductions in breast cancer and increased risks of thromboembolic events and endometrial cancer. Readily identifiable subsets of individuals comprising 2.5 million women could derive a net benefit from the drug.

[Title]: Phase II trial of low-dose paclitaxel and cisplatin in patients with advanced gastric cancer.
[Abstract]: BACKGROUND: Paclitaxel has shown promising activity in gastric cancer and has synergism with cisplatin. This study was performed to evaluate the efficacy and toxicity of low-dose paclitaxel (145 mg/m(2)) plus cisplatin chemotherapy in metastatic or relapsed gastric cancer. METHODS: Chemotherapy-naive patients with metastatic or relapsed gastric cancer were enrolled. Paclitaxel 145 mg/m(2) was administered intravenously over 3 h, followed by cisplatin 60 mg/m(2) on Day 1 every 3 weeks in the outpatient setting. RESULTS: Of 39 patients enrolled, 17 (44%) had partial responses. Twelve (31%) had stable disease and eight (21%) progressive disease. Two patients (5%) were not evaluable because of early drop-out. The median time to progression was 4.7 months and the median overall survival was 12.1 months. The most common hematologic toxicity was anemia (41%). Grade 3/4 neutropenia and thrombocytopenia developed in 14 and 3%, respectively. The most common non-hematologic toxicities were peripheral neuropathy (43%) and emesis (43%). Grade 3/4 non-hematologic toxicities included emesis (11%), peripheral neuropathy (3%), diarrhea (3%) and hepatotoxicity (3%). CONCLUSIONS: Low-dose paclitaxel and cisplatin chemotherapy was active and well-tolerated in chemotherapy-naive gastric cancer patients. This regimen seems to have comparable efficacy to previously reported higher-dose paclitaxel plus cisplatin-containing regimens and fewer toxicities.

[Title]: Effect of the non-steroidal anti-inflammatory drug sulindac on colorectal adenomas of uncolectomized familial adenomatous polyposis.
[Abstract]: BACKGROUND: The aim of the present study was to elucidate the effect of sulindac on uncolectomized familial adenomatous polyposis (FAP). METHODS: Seven FAP patients (SU group) without proctocolectomy were given sulindac 300 mg/day orally for 12 months. Six FAP patients without sulindac (non-SU group) served as controls. Colorectal lesions were assessed by protrusion index (no. radiolucent areas/cm(2); PI) under barium enema examination and non-polypoid lesion were assessed under chromoscopy prior to and at the end of the observation period. In the SU group, germline adenomatous polyposis coli (APC) mutation was determined by protein truncation test. RESULTS: In the SU group, PI decreased significantly in the distal colon (from 3.0 +/- 1.1 to 1.1 +/- 0.8/cm(2), P &lt; 0.02) and in the proximal colon (from 3.4 +/- 2.4 to 0.9 +/- 1.3/cm(2), P &lt; 0.02). The PI in the non-SU group slightly but significantly increased in the distal colon (from 1.0 +/- 0.8 to 1.2 +/- 0.9/cm(2); P &lt; 0.05) and it remained unchanged in the proximal colon (from 0.6 +/- 0.3 to 0.7 +/- 0.3/cm(2); P &gt; 0.05). Chromoscopy at the end of observation identified non-polypoid lesions in five patients in the SU group, whereas such lesions were not found in the non-SU group (71% vs 0%, P = 0.016). Decrease in PI was not different among distal APC mutation (exons 1-9), proximal APC mutation (exons 10-15) and negative mutation. CONCLUSION: Sulindac reduces colorectal adenomas of protruding type in uncolectomized FAP. The effect of sulindac may be unrelated to genotype of FAP.

[Title]: Quetiapine for insomnia associated with refractory depression exacerbated by phenelzine.
[Abstract]: OBJECTIVE: To report the successful treatment of phenelzine-associated insomnia with low-dose quetiapine in a patient with refractory depression. CASE SUMMARY: A 42-year-old white man with severe major depression unresponsive to selective serotonin-reuptake inhibitors, bupropion, and tricyclic antidepressants improved following treatment with the monoamine oxidase inhibitor (MAOI) phenelzine. Insomnia, present to a moderate degree prior to antidepressant therapy, worsened markedly following phenelzine treatment and failed to respond to diphenhydramine, temazepam, triazolam, clonazepam, zolpidem, or trazodone given at high therapeutic doses. Sleep disturbance resolved with low-dose (50 mg) adjunctive quetiapine, with no adverse effects. DISCUSSION: Major depression refractory to standard therapy is a common and serious condition. Some cases respond to MAOIs; however, orthostatic hypotension and insomnia frequently occur. Potentially serious MAOI interactions with psychotropic drugs have raised concerns about combining these agents. In this case, a failure of a number of other medications known to treat MAOI-associated insomnia safely prompted a trial of quetiapine. Despite the possibility that enhanced serotonergic activity might have resulted in serotonin syndrome, no adverse interactions between phenelzine and quetiapine were noted. The use of low-dose, once-daily quetiapine, along with its unique binding properties, may account for its increased safety in combination with phenelzine. CONCLUSIONS: This case illustrates that low-dose quetiapine may be an alternative treatment for phenelzine-associated insomnia. Further case reports are needed to establish the safety and effectiveness of combining these agents.

[Title]: Drug concentration monitoring with tolerability and efficacy assessments during open-label, long-term sertraline treatment of children and adolescents.
[Abstract]: OBJECTIVE: The aim of this study was to evaluate the long-term pharmacokinetics, safety, and efficacy of sertraline in children and adolescents with obsessive-compulsive disorder (OCD) or major depressive disorder (MDD). METHOD: After 42-day initial treatment and 9-day withdrawal phases, children (6-12 years, n = 16) and adolescents (13-18 years, n = 27) entered a 24-week open-label phase, with sertraline titrated to 200 mg/day. Blood samples for plasma sertraline and N-desmethylsertraline levels were taken at the beginning of the 24-week phase and at weeks 1, 4, 8, 12, and 24. Efficacy and safety data were also collected. RESULTS: Mean maximum daily dose at endpoint was 157 +/- 49 mg. For female and male children, mean sertraline/N-desmethylsertraline concentrations normalized to a 200-mg dose were 85.0/160 ng/mL (n = 8) and 79.3/134 ng/mL (n = 8), respectively, and for female and male adolescents, 70.5/109 ng/mL (n = 16) and 76.3/120 ng/mL (n = 8). No significant age or gender effects or age-by-gender interactions were observed in sertraline values. Mean sertraline plasma concentrations normalized for dose and body weight did not differ significantly by age or gender. Three (3) patients (7%) discontinued owing to adverse events. In patients with OCD (n = 10), improvements were observed in Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) (p = 0.029) and National Institute of Mental Health (NIMH) Global Obsessive Compulsive Scale (OCS) (p = 0.01). In MDD patients (n = 32), Clinical Global Impression (CGI) Severity (p = 0.002) and Improvement (p = 0.011) improved. CONCLUSIONS: Long-term treatment of MDD and OCD with sertraline up to 200 mg/day in children and adolescents results in dose-normalized plasma concentrations comparable to those seen in adults. Sertraline was generally well tolerated, and patients demonstrated clinical improvement over 24 weeks of treatment.

[Title]: After myocardial infarction carvedilol improves insulin resistance compared to metoprolol.
[Abstract]: PRINCIPLES: Both carvedilol and metoprolol have cardioprotective effects and decrease infarct size in myocardium. We compared effects of carvedilol and metoprolol on insulin resistance and serum lipid levels after myocardial infarction. METHODS: Fifty-nine patients aged between 30 and 70 and BMI = 25-30 kg/m2, who were diagnosed with myocardial infarction with ST segment elevation, were considered to be eligible for the study. Patients were randomly allocated to two different therapy protocols. Metoprolol 100 mg bid or carvedilol 25 mg bid was added to their standardized therapy regimen. Baseline to week 4 and 12, fasting blood glucose, serum lipid profile, BMI, C-peptide, insulin and homeostasis model assessment of insulin resistance (HOMA-IR) were measured. RESULTS: After 12 weeks of metoprolol therapy HOMA-IR, insulin and C-peptide levels were significantly higher (p &lt; 0.05 for all) and total cholesterol and triglyceride levels decreased significantly (p &lt; 0.05 for all) compared to baseline. After 12 weeks of carvedilol therapy HOMA-IR, insulin and C-peptide (p &lt; 0.05 for all), total cholesterol and triglyceride (p = 0.001 for all) decreased significantly compared to baseline. Carvedilol provided more decrease in total cholesterol and LDL levels than metoprolol (p = 0.043 and p = 0.021, respectively). CONCLUSIONS: In patients after myocardial infarction, carvedilol added to background therapy improved insulin resistance and lipid profile.

[Title]: [Comparison of the antiemetic effectiveness of granisetron and alizapride plus dexamethasone in cytostatic therapy].
[Abstract]: In a randomized single-blind international multicentre trial, two antiemetic regimens were compared in 115 oncology patients undergoing chemotherapy for the first time (cisplatin greater than 15 mg/m2, or ifosfamide greater than 1200 mg/m2 or etoposide greater than 120 mg/m2). One group received granisetron, a 5-hydroxytryptamine type-3-receptor antagonist, 40 micrograms/kg alone intravenously before chemotherapy, with, if necessary, up to two further doses daily of 40 micrograms/kg. The second group received a combination of alizapride plus dexamethasone (4 mg/kg alizapride and 8 mg/kg dexamethasone before chemotherapy, repeated, if necessary, after 4 and 8 hours up to two additional doses). There was good antiemetic efficacy (a maximum of one episode of vomiting in 24 hours = "major efficacy") in 50 of 62 patients (80.7%) in the granisetron group, and in 37 out of 53 (69.8%) of those treated with alizapride and dexamethasone; failure of antiemetic therapy occurred in 4.8% (granisetron) and 15.1% (combination) of patients. For the first day of each 5-day chemotherapy cycle, there was a higher rate of excellent antiemetic efficacy (no or only mild nausea, and no vomiting) with granisetron (90.3% vs 69.8%, P less than 0.006). The frequency (29% vs 32%) and nature of side effects (obstipation, diarrhoea, headaches, anxiety, vertigo), the causes of which were not differentiated, were similar. No extrapyramidal reactions occurred with granisetron. Of the 62 patients treated with granisetron, 47 did not require any further granisetron after the single daily prophylactic dose.
