The epidemiology of hypertension among hemodialysis (HD) patients is difficult to describe accurately because of difficulties in the assessment of blood pressure (BP). ⋯ Interdialytic hypertension is highly prevalent and difficult to control among HD patients. End-expiration IVC diameter is associated with poor control of hypertension in cross-sectional analyses as well as after washout of antihypertensive drugs. Among HD patients, an attractive target for improving hypertension control appears to be the reduction of extracellular fluid volume.

Contrast-induced nephropathy (CIN) remains a leading cause of iatrogenic acute renal failure. Terlipressin, a long-acting analog of vasopressin, may improve renal function. This study aimed to investigate the possible protective effect of terlipressin against the development of experimental CIN in rats. ⋯ These results demonstrate that terlipressin can inhibit the development of CIN.

Acute kidney injury (AKI) is common in patients undergoing cardiac surgery and is associated with a high rate of death, long-term sequelae and healthcare costs. We conducted a systematic review of randomized controlled trials for strategies to prevent or treat AKI in cardiac surgery. ⋯ This summary of all the literature on prevention and treatment strategies for AKI in cardiac surgery highlights the need for better information. The results advocate large, good-quality, multicenter studies to determine whether promising interventions reliably reduce rates of acute renal replacement therapy and mortality in the cardiac surgery setting.

Contrast-induced acute kidney injury (CI-AKI) is an important cause of acute renal injury. Several clinical trials using renal replacement therapy (RRT) for prevention of CI-AKI yielded conflicting results. We performed a meta-analysis to assess the efficacy of prophylactic RRT on CI-AKI. ⋯ RRT fails to reduce the incidence of CI-AKI in CKD stage 3 patients, but may be beneficial in patients with more advanced renal function. CRRT is more effective than hemodialysis for prevention of CI-AKI. RRT is effective in reducing the in-hospital mortality of CI-AKI patients.

hypertension is a modifiable risk factor in chronic kidney disease (CKD), and medication adherence (MA) is critical in reaching the treatment goals. Patterns of MA for antihypertensive agents and its impact on blood pressure (BP) in CKD practice settings are not well studied. ⋯ 33% of CKD patients have Poor MA for antihypertensive agents, and MA worsens with declining renal function. Poor MA is associated with a 23% greater risk of uncontrolled hypertension. Monitoring and improving adherence in CKD practice may improve outcomes.
