Objectives

Narrative objectives1

Angiotensin II type 1 receptor blockers (ARB) have shown various protective effects to the cardiovascular system. However, using ARB is associated with several adverse effects including worsening of hyperkalemia and anemia, especially in end-stage renal disease (ESRD) patients. Cardiovascular diseases are the main cause of death in ESRD patients, and cardiovascular risk in patients on continuous ambulatory peritoneal dialysis (CAPD) may differ from that in those on hemodialysis (HD). Maintaining extracellular fluid and salt balance is a major challenge in dialysis patients, and especially so in CAPD patients with minimal or no residual diuresis. The degree of left ventricular dysfunction is suggested to be more severe in long-term CAPD patients than in HD patients with more pronounced volume expansion, hypertension, and hypoalbuminemia. This study was performed to examine whether ARB is useful for the treatment of hypertension in CAPD patients.

Medicine

Interventions/Control_1

ARB group: Start with once-daily dosing of valsartan 20-40 mg or candesartan 2-4 mg, and increase up to 80-160 mg for valsartan and 8-12 mg for candesartan, respectively, if effects of valsartan or candesartan on the clinical parameters are insufficient. Target blood pressure is less than 140/90 mmHg.

Interventions/Control_2

Control therapy group: Treated with anti-hypertensives principally by other than ARBs or ACE inhibitors.Target blood pressure is less than 140/90 mmHg.
