Abstract Background The potential long-term safety and efficacy of aliskiren in nondiabetic chronic kidney disease (CKD) are unknown. We sought to investigate the renoprotective effect of aliskiren on nondiabetic CKD patients. Methods In this open-label, parallel, randomized controlled trial, nondiabetic CKD Stages 3–4 patients were randomized to receive aliskiren added to an angiotensin II receptor blocker (ARB) at the maximal tolerated dose, or ARB alone. Primary outcome was the rate of change in estimated glomerular filtration rate (eGFR). Secondary endpoints included rate of change in urine protein-to-creatinine ratio (UPCR), cardiovascular events and hyperkalemia. Composite renal outcomes of doubling of baseline serum creatinine or a 40% reduction in eGFR or incident end-stage renal disease or death were analyzed as post hoc analysis. Results Seventy-six patients were randomized: 37 to aliskiren (mean age 55.1 ± 11.1 years) and 39 to control (mean age 55.0 ± 9.4 years). Their baseline demographics were comparable to eGFR (31.9 ± 9.0 versus 27.7 ± 9.0 mL/min/1.73 m2, P = 0.05) and UPCR (30.7 ± 12.6 versus 47.8 ± 2.8 mg/mmol, P = 0.33) for treatment versus control subjects. After 144 weeks of follow-up, there was no difference in the rate of eGFR change between groups. Six patients in the aliskiren group and seven in the control group reached the renal composite endpoint (16.2% versus 17.9%, P = 0.84). The cardiovascular event rate was 10.8% versus 2.6% (P = 0.217). The hyperkalemia rate was 18.9% versus 5.1% with an adjusted hazard ratio of 7.71 (95% confidence interval 1.14 to 52.3, P = 0.04) for the aliskiren arm. Conclusion Aliskiren neither conferred additional renoprotective benefit nor increased adverse events, except for more hyperkalemia in nondiabetic CKD patients.

The current population is characterized by a high prevalence of risk factors for the development of chronic kidney disease: hypertension, diabetes, obesity, metabolic syndrome, physical inactivity, smoking. The development of severe complications and a close connection with potentially fatal cardiovascular disorders make this disease a socially and economically significant problem. Treatment of chronic kidney disease in advanced stages belong to nephrologist duties. However, the success of preventive interventions depends on the time of their onset, which makes it relevant to identify the disease. The use of nephroprotective approaches by physicians of different specialties (general practitioners, cardiologists, gerontologists, nephrologists, endocrinologists) can significantly improve the prognosis of both those at risk of developing renal dysfunction and the existing disease. The review presents data on the clinical and laboratory efficacy of angiotensin-renin blocker use, as well as the combination of angiotensin II receptor blockers with calcium antagonists. Using the combination of the angiotensin II receptor blocker irbesartan and amlodipine as an example, we demonstrated the possibilities of nephroprotective therapy in patients with renal dysfunction.

ObjectivesAlterations in dopamine neurotransmission underlie some of the clinical features of Huntington’s disease (HD) and as such are a target for therapeutic intervention, especially for the treatment of chorea and some behavioural problems. However, justification for such an intervention is mainly based on case reports and small open label studies and the effects these drugs have on cognition in HD remain unclear.MethodsIn this study, we used the Enroll-HD observational database to assess the effects of antidopaminergic medication on motor, psychiatric and cognitive decline, over a 3-year period. We first looked at the annual rate of decline of a group of HD patients taking antidopaminergic medication (n=466) compared with an untreated matched group (n=466). The groups were matched on specified clinical variables using propensity score matching. Next, we studied a separate group of HD patients who were prescribed such medications part way through the study (n=90) and compared their rate of change before and after the drugs were introduced and compared this to a matched control group.ResultsWe found that HD patients taking antidopaminergic medication had a slower progression in chorea and irritability compared with those not taking such medications. However, this same group of patients also displayed significantly greater rate of decline in a range of cognitive tasks.ConclusionIn conclusion we found that antidopaminergic treatment is associated with improvements in the choreic movements and irritability of HD but worsens cognition. However, further research is required to prospectively investigate this and whether these are causally linked, ideally in a double-blind placebo-controlled trial.

BACKGROUND Despite the growing burden of chronic kidney disease (CKD), disease knowledge and understanding are still lacking, especially in Bangladesh. OBJECTIVE The aim of this study was to evaluate the outcome of a health education intervention in order to enhance knowledge, health-related quality of life (QOL), and motivation regarding healthy lifestyles among rural and periurban adults suffering from CKD. METHODS A parallel-group (1:1) randomized controlled trial is ongoing in the Mirzapur subdistrict, Bangladesh, where two groups of patients with CKD are being compared. Patients aged 18 years and over with CKD (stages 1-3) were enrolled in November 2020. Patients were randomly allocated into either the intervention group (n=63) or the control group (n=63). The control group received usual treatment, while the intervention group received health education through a CKD campaign facilitated by a nephrologist and via mHealth (ie, periodic mobile phone calls) from community health workers. Both groups were followed up for a period of 6 months. The primary endpoint is patients’ increased knowledge measured using the Chronic Kidney Disease Knowledge Questionnaire. The secondary endpoints are improved QOL measured using the standardized EuroQol 5-Dimension 5-Level (EQ-5D-5L) questionnaire as well as improvements in the levels of blood pressure, BMI, serum creatinine, fasting blood sugar, hemoglobin, cholesterol, high-density lipoprotein cholesterol, triglyceride, serum uric acid, blood urea nitrogen, and albumin to creatinine ratio. RESULTS Enrollment of participants began in November 2020; the intervention and follow-up were completed in May 2021. We enrolled 126 patients in the study. Patients’ mean ages were 57.97 (SD 15.03) years in the control group and 57.32 (SD 14.37) years in the intervention group. There were 45 out of 63 (71%) females in the control group and 38 out of 63 (60%) females in the intervention group. In addition, there were 38 out of 63 (60%) literate patients in the control group and 33 out of 63 (52%) literate patients in the intervention group. CONCLUSIONS It is expected that a combined approach, incorporating both a CKD campaign and mHealth, for health education may be an effective tool for increasing knowledge and improving QOL among patients with CKD.

Background In the Dapagliflozin And Prevention of Adverse Outcomes in Chronic Kidney Disease (DAPA-CKD) randomized placebo-controlled trial, the sodium-glucose cotransporter 2 inhibitor dapagliflozin significantly reduced risk of kidney failure and prolonged survival in CKD patients with or without type 2 diabetes. Methods In this prespecified analysis of dapagliflozin's effects in patients with stage 4 CKD (eGFR<30 mL/min per 1.73m2) at baseline, we randomized adults with eGFR of 25-75 mL/min per 1.73m2 and urinary albumin-to-creatinine ratio of 200-5000 mg/g to receive dapagliflozin 10 mg/day or placebo. The primary outcome was a composite of time to ≥50% sustained decline in eGFR, end-stage kidney disease, or kidney or cardiovascular death. Secondary outcomes were a kidney composite (same as the primary endpoint but without cardiovascular death), a composite of cardiovascular death or heart failure hospitalization, and all-cause death. Results A total of 293 participants received dapagliflozin and 331 received placebo. Relative to placebo, dapagliflozin was associated with reductions in the primary composite endpoint (hazard ratio [HR], 0.73; 95% confidence interval [95% CI], 0.53 to 1.0), the kidney endpoint (HR, 0.71; 95% CI, 0.49 to 1.02), the cardiovascular endpoint (HR, 0.83; 95% CI, 0.45 to 1.53), and the mortality endpoint (HR, 0.68; 95% CI, 0.39 to 1.21). The eGFR slope declined by 2.15 and 3.38 mL/min per 1.73m2 per year in the dapagliflozin and placebo groups, respectively (P=0.005). Patients treated with dapagliflozin or placebo had similar rates of serious adverse events and adverse events of interest. Conclusions Among patients with stage 4 CKD and albuminuria, dapagliflozin's benefits were consistent with those observed in the DAPA-CKD trial overall, with no evidence of increased risks.
