Comparative Study of Prognosis and QOL Between APD-RPM and CAPD

This is an observational study based on the real-word diagnosis and treatments. Target subject population include end-stage renal disease patients (aged 18-75 years) with peritoneal dialysis 3 months and longer. Standard peritoneal balance test of eligible patients should be rapid peritoneal solute transfer rate (4-hour D/P creatinine value \> 0.65). Patients will be divided into two groups to receive standard APD-RPM or CAPD with a ratio of 1:2. Peritoneal dialysis in APD-RPM group (n=250): (1) APD mode is recommended but not limited to continuous circulating peritoneal dialysis (CCPD); (2) Dialysis dose ranges from 5 to 10 liters per day and depends on previous APD prescription and dialysis adequacy; (3) Glucose concentration starts from low concentration (1.5%) and depends on previous dialysis prescription. Peritoneal dialysis in CAPD group (n=500): (1) Dialysis dose ranges from 5 to 10 liters per day at the run-in period. For those with regular peritoneal dialysis, the original dose can be used according to the volume status and solute clearance effect in the past 3 months; (2) Exchange time and abdominal retention time is generally 2-5 times and 1 time at daytime and night, separately; (3) Glucose concentration includes 1.5%, 2.5% or 4.25%; (4) The treatments can be adjusted according to the change of residual renal function, peritoneal transport characteristics, volume status, solute clearance, clinical status and peritonitis.
