Randomized Controlled Trial Comparing Residual Renal Function in Patients Undergoing Three or Four Exchanges CAPD - Full Text View

Purpose

The purpose of this study was to explore the impacts of different continuous ambulatory peritoneal dialysis (CAPD) dosage (three 2-Liter exchanges CAPD vs. four 2-Liter exchanges CAPD) on residual renal function, technique survival and peritonitis rate in incident Chinese peritoneal dialysis patients.

Primary Outcome Measures:

The changes in residual renal function including urine volume and residual glomerular filtration rate. [ Time Frame: Month 1 and 24 after CAPD initiation ] [ Designated as safety issue: No ]
Number of participants developing to anuria (permanently daily urine volume less than 200ml) [ Time Frame: Up to 24 months after CAPD initiation ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Number of participants having technique failure including death and switching to maintenance hemodialyisis [ Time Frame: Up to 24 months after CAPD initiation. ] [ Designated as safety issue: Yes ]
Episodes of peritonitis [ Time Frame: Up to 24 months after CAPD initiation ] [ Designated as safety issue: Yes ]

Arms	Assigned Interventions
Experimental: Three 2-liter exchanges group A group of randomly assigned patients undergoing three 2-liter exchanges daily CAPD.	Other: Three 2-liter exchanges daily CAPD CAPD regimen of three 2-liter daily exchanges Other Name: small volume CAPD
Active Comparator: Four 2-liter exchanges group A group of randomly assigned patients undergoing four 2-liter exchanges daily CAPD.	Other: Three 2-liter exchanges daily CAPD CAPD regimen of three 2-liter daily exchanges Other Name: small volume CAPD

Detailed Description:

The primary end point for this study was changes in RRF including 24-h urine volume and residual GFR. These were evaluated at month 1, which was defined as the baseline, and then at month 6, 12, 18 and 24. At the same time, body weight, blood pressure, daily net ultrafiltration, and dialysis adequacy were assessed. Once an episode of peritonitis or other serious reversible intercurrent illness occurred, all the assessments were delayed one month after being cured. Anuria was termed by daily Uvol permanently less than 200 ml.
The secondary end points included technique survival and peritonitis rate. Technique failure was defined as both death and switch to maintenance hemodialysis.
