Nifedipine plus candesartan combination increases blood pressure control regardless of race and improves the side effect profile: DISTINCT randomized trial results.

ABSTRACT: DISTINCT (reDefining Intervention with Studies Testing Innovative Nifedipine GITS - Candesartan Therapy) aimed to determine the dose-response and tolerability of nifedipine GITS and/or candesartan cilexetil therapy in participants with hypertension.In this 8-week, multinational, multicentre, randomized, double-blind, placebo-controlled study, adults with mean seated DBP of at least 95 to less than 110?mmHg received combination or monotherapy with nifedipine GITS (N) 20, 30 or 60?mg and candesartan cilexetil (C) 4, 8, 16 or 32?mg, or placebo. The primary endpoint, change in DBP from baseline to Week 8, was analysed using the response surface model (RSM); this analysis was repeated for mean seated SBP.Overall, 1381 participants (mean baseline SBP/DBP: 156.5/99.6?mmHg) were randomized. Both N and C contributed independently to SBP/DBP reductions [P?

Project description:Objective: In obese men, the increased expression of the aromatase enzyme in adipose tissue leads to high conversion of androgens to estrogens contributing to hypogonadotropic hypogonadism (HHG). Our objective is to evaluate efficacy and safety of weight loss (WL) plus aromatase inhibitor (AI) therapy in severely obese men with HHG. We hypothesize that AI+WL will be more effective as compared to WL alone in improving the hormonal profile, thus muscle strength and symptoms of HHG (primary outcomes), with no significant adverse effects on lean mass, metabolic profile, and bone mineral density (secondary outcomes). Design: Randomized double-blind placebo-controlled pilot trial. Methods: Twenty-three obese men (BMI≥35 kg/m2), 35-65 years old, were randomized to weight loss (diet and exercise) plus either anastrozole (AI+WL, n = 12) at 1 mg daily or placebo (PBO+WL, n = 11) for 6 months. Inclusion criteria: total testosterone <300 ng/mL (average of 2 measurements), estradiol≥10.9 pg/ml, LH <9 IU/l. Symptoms of hypogonadism by questionnaires; muscle strength by Biodex dynamometer; body composition and bone mineral density by dual-energy X-ray absorptiometry; bone microarchitecture and finite element analysis by high resolution peripheral quantitative-computed tomography. Results: After 6 months of therapy, AI+WL group had higher testosterone (p = 0.003) and lower estradiol (p = 0.001) compared to PBO+WL. Changes in symptoms and muscle strength did not differ between groups. AI+WL resulted in higher fat mass loss than PBO+WL (p = 0.04) without differences in changes in lean mass. Total and LDL cholesterol reduced more in the PBO+WL group compared to AI+WL (p = 0.03 for both), who experienced a minimal increase with unlikely meaningful clinical impact. Tibial trabecular bone area decreased more in PBO+WL than AI+WL group for which it remained stable (p = 0.03). Conclusions:Although AI+WL is effective in reversing the hormonal profile of HHG in severely obese men without causing major side effects, it does not lead to greater improvements in muscle strength and symptoms of hypogonadism compared to WL alone.

Project description:Different types of graft-versus-host disease prophylaxis have been proposed in the setting of reduced intensity and non-myeloablative allogeneic stem cell transplantation. An alternative combination with sirolimus and tacrolimus has recently been tested although comparative studies against the classical combination of a calcineurin inhibitor and mycophenolate mofetil or methotrexate are lacking. We describe the results of a prospective, multicenter trial using sirolimus + tacrolimus as immunoprophylaxis, and compare this approach with our previous experience using cyclosporine + mycophenolate in the setting of unrelated donor transplantation setting after reduced-intensity conditioning. Forty-five patients received cyclosporine + mycophenolate between 2002 and mid-2007, while the subsequent 50 patients, who were transplanted from late 2007, were given sirolimus + tacrolimus. No significant differences were observed in terms of hematopoietic recovery or acute graft-versus-host disease overall, although gastrointestinal acute graft-versus-host disease grade ≥ 2 was more common in the cyclosporine + mycophenolate group (55% versus 21%, respectively, P=0.003). The 1-year cumulative incidence of chronic graft-versus-host disease was 50% versus 90% for the patients treated with the sirolimus- versus cyclosporine-based regimen, respectively (P<0.001), while the incidence of extensive chronic disease was 27% versus 49%, respectively (P=0.043). The 2-year non-relapse mortality rate was 18% versus 38% for patients receiving the sirolimus- versus the cyclosporine-based regimen, respectively (P=0.02). The event-free survival and overall survival at 2 years were 53% versus 29% (P=0.028) and 70% versus 45% (P=0.018) among patients receiving the sirolimus- versus the cyclosporine-based regimen, respectively. In conclusion, in the setting of reduced intensity transplantation from an unrelated donor, promising results can be achieved with the combination of sirolimus + tacrolimus, due to a lower risk of chronic graft-versus-host disease and non-relapse mortality, which translates into better event-free and overall survival rates, in comparison with those achieved with cyclosporine + mycophenolate.

Project description:BackgroundObservational studies can provide important information on the efficacy and safety of antihypertensive agents in the real-life clinical setting. AdADOSE was a large observational study to assess the effectiveness of nifedipine GITS in combination with other antihypertensive agent(s). The study was also the first to examine the role of combination therapy with nifedipine GITS in the Middle East, Pakistan and Russia, regions that are associated with particularly high cardiovascular risk.MethodsAdADOSE was a 12-week, international, multicenter, prospective, observational study. Patients with hypertension (ie, blood pressure [BP] >140/90 mm Hg, or >130/80 mm Hg in patients at high or very high cardiovascular risk) received once-daily nifedipine GITS (30, 60 or 90 mg) in combination with another antihypertensive or as add-on to existing therapy. The primary study endpoint was the proportion of patients who achieved the target BP of <140/90 mm Hg (or <130/80 mm Hg for those at high or very high cardiovascular risk). Study outcomes are reported by descriptive statistics.ResultsThe study enrolled 4497 patients (n = 4477, safety population; n = 3430, efficacy population). Baseline mean systolic/diastolic BP (SBP/DBP) was 166.4/99.7 mm Hg; 85.2 % of patients had received prior antihypertensive treatment, and 90.6 % had ≥ 1 concomitant diseases. Following combination treatment with nifedipine GITS, target BP was achieved by 64.8% of patients without concomitant diseases, and by 56.5%, 32.3% and 22.6% with 1, 2-3 and >3 concomitant diseases, respectively. The proportion of patients achieving target BP was 51.5% in previously untreated and 33.7% in previously treated patients. Nifedipine GITS combination treatment provided mean SBP/DBP changes of -36.1/-18.8 mm Hg in all patients, -40.2/-21.5 mm Hg in previously untreated patients, and -35.6/-18.4 mm Hg in previously treated patients, with similar BP reductions irrespective of the number of concomitant diseases. Drug-related adverse events (AEs) were reported in 2.6% patients. There were no serious AEs and only 0.8% of patients discontinued due to drug-related AEs.ConclusionsCombination therapy with nifedipine GITS in a real-life observational setting was highly effective in reducing SBP/DBP in a range of hypertensive patients, with low rates of treatment-related AEs.Trial registrationTrial registrationat ClinicalTrials.gov registration number NCT01118286 .
