Treatment outcomes for drug resistant tuberculosis among children below 15 years in Kenya, 2010‐2016

Background: Tuberculosis is a common cause of morbidity and mortality in children. Children are less likely to acquire resistance during the treatment of tuberculosis (TB). Most of the drug resistant TB infection in children is transmitted from adults.Objective: To determine the characteristics and treatment outcomes among children below 15 years managed for drug resistant TB in Kenya, 2010 – 2016.Design: Retrospective descriptive study.Setting: All health facilities managing drug resistant TB in KenyaSubjects: Children below 15 years treated for drug resistant TB between 2010 and 2016.Results: Sixty three children were notified with DR TB between 2010 and 2016. The median (IQR) age was11 (10‐13) years with a female to male ratio of 1:1. With 32 (52%) and 31 (51%) with smear and culture positive laboratory results respectively. Primary drug resistance was present in 25 (40%) of the children All the sputum and culture converted negative at month three of treatment. HIV testing uptake was 100% with a positivity rate of 26 (41%) and 100% anti‐retroviral therapy uptake. The treatment success rate for the cases was 31(91%) with a mortality rate of 2(5%) and lost‐to‐follow up 1 (3%).Conclusion: Drug‐resistant tuberculosis can be successfully treated and therapy well tolerated among children. There  is need for contact tracing and screening for all at risk including paediatric population

Effect of aliskiren on post-discharge outcomes among diabetic and non-diabetic patients hospitalized for heart failure: insights from the ASTRONAUT trial

Aims The objective of the Aliskiren Trial on Acute Heart Failure Outcomes (ASTRONAUT) was to determine whether aliskiren, a direct renin inhibitor, would improve post-discharge outcomes in patients with hospitalization for heart failure (HHF) with reduced ejection fraction. Pre-specified subgroup analyses suggested potential heterogeneity in post-discharge outcomes with aliskiren in patients with and without baseline diabetes mellitus (DM). Methods and results ASTRONAUT included 953 patients without DM (aliskiren 489; placebo 464) and 662 patients with DM (aliskiren 319; placebo 343) (as reported by study investigators). Study endpoints included the first occurrence of cardiovascular death or HHF within 6 and 12 months, all-cause death within 6 and 12 months, and change from baseline in N-terminal pro-B-type natriuretic peptide (NT-proBNP) at 1, 6, and 12 months. Data regarding risk of hyperkalaemia, renal impairment, and hypotension, and changes in additional serum biomarkers were collected. The effect of aliskiren on cardiovascular death or HHF within 6 months (primary endpoint) did not significantly differ by baseline DM status (P = 0.08 for interaction), but reached statistical significance at 12 months (non-DM: HR: 0.80, 95% CI: 0.64-0.99; DM: HR: 1.16, 95% CI: 0.91-1.47; P = 0.03 for interaction). Risk of 12-month all-cause death with aliskiren significantly differed by the presence of baseline DM (non-DM: HR: 0.69, 95% CI: 0.50-0.94; DM: HR: 1.64, 95% CI: 1.15-2.33; P < 0.01 for interaction). Among non-diabetics, aliskiren significantly reduced NT-proBNP through 6 months and plasma troponin I and aldosterone through 12 months, as compared to placebo. Among diabetic patients, aliskiren reduced plasma troponin I and aldosterone relative to placebo through 1 month only. There was a trend towards differing risk of post-baseline potassium ≥6 mmol/L with aliskiren by underlying DM status (non-DM: HR: 1.17, 95% CI: 0.71-1.93; DM: HR: 2.39, 95% CI: 1.30-4.42; P = 0.07 for interaction). Conclusion This pre-specified subgroup analysis from the ASTRONAUT trial generates the hypothesis that the addition of aliskiren to standard HHF therapy in non-diabetic patients is generally well-tolerated and improves post-discharge outcomes and biomarker profiles. In contrast, diabetic patients receiving aliskiren appear to have worse post-discharge outcomes. Future prospective investigations are needed to confirm potential benefits of renin inhibition in a large cohort of HHF patients without D

Cause of Death and Predictors of All-Cause Mortality in Anticoagulated Patients With Nonvalvular Atrial Fibrillation : Data From ROCKET AF

M. Kaste on työryhmän ROCKET AF Steering Comm jäsen.Background-Atrial fibrillation is associated with higher mortality. Identification of causes of death and contemporary risk factors for all-cause mortality may guide interventions. Methods and Results-In the Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (ROCKET AF) study, patients with nonvalvular atrial fibrillation were randomized to rivaroxaban or dose-adjusted warfarin. Cox proportional hazards regression with backward elimination identified factors at randomization that were independently associated with all-cause mortality in the 14 171 participants in the intention-to-treat population. The median age was 73 years, and the mean CHADS(2) score was 3.5. Over 1.9 years of median follow-up, 1214 (8.6%) patients died. Kaplan-Meier mortality rates were 4.2% at 1 year and 8.9% at 2 years. The majority of classified deaths (1081) were cardiovascular (72%), whereas only 6% were nonhemorrhagic stroke or systemic embolism. No significant difference in all-cause mortality was observed between the rivaroxaban and warfarin arms (P=0.15). Heart failure (hazard ratio 1.51, 95% CI 1.33-1.70, P= 75 years (hazard ratio 1.69, 95% CI 1.51-1.90, P Conclusions-In a large population of patients anticoagulated for nonvalvular atrial fibrillation, approximate to 7 in 10 deaths were cardiovascular, whereasPeer reviewe

A phase II trial of Afimoxifene (4-hydroxytamoxifen gel) for cyclical mastalgia in premenopausal women

Background Many women experience symptoms of cyclical mastalgia, such as breast pain, tenderness, and nodularity. Tamoxifen and other drugs have been used to alleviate cyclical mastalgia symptoms; however, their use is associated with potentially serious side effects. The current study compared the safety and efficacy of two doses of a topical gel containing 4-hydroxytamoxifen (Afimoxifene, formerly known as 4-OHT) with placebo gel for the treatment of moderate to severe cyclical mastalgia. Methods Premenopausal women aged at least 18 years experiencing moderate to severe symptoms were randomized to receive placebo, 2 mg, or 4 mg of Afimoxifene daily delivered as a transdermal hydroalcoholic gel for 4 menstrual cycles. The primary efficacy parameter was change in mean pain intensity as measured by the Visual Analog Scale (VAS) for the seven worst pain score days within a cycle from baseline to the fourth cycle. Results After 4 cycles of treatment, statistically significant improvements relative to placebo were measured in mean VAS score in the 4-mg Afimoxifene group (−12.71 mm [95% confidence interval, −0.96 to −24.47; P = 0.034]). Patient global assessment of pain, physician’s assessment of pain, tenderness on palpation, and nodularity following 4 cycles of treatment were significantly more likely to show improvements in the 4-mg group, compared with placebo (P = 0.010 [pain]; P = 0.012 [tenderness]; P = 0.017 [nodularity]). Overall, Afimoxifene was well tolerated with few adverse events and no drug-related SAE occurred in any group. There were no changes in menstrual pattern or plasma hormone levels and no breakthrough vaginal bleeding in patients treated with Afimoxifene. Conclusion After 4 months of treatment, daily topical breast application of Afimoxifene resulted in statistically significant improvements in signs and symptoms of cyclical mastalgia across patient- and physician-rated scales with excellent tolerability and safety
