Effect of Different Dialysis Dosage on Prognosis in Maintenance Peritoneal Dialysis Patients

Effect of Different Dialysis Dosage on Prognosis in Maintenance Peritoneal Dialysis Patients - A Prospective, Randomized, Controlled, Multi-center Clinical Study

Peritoneal dialysis (PD) is an important model of renal replacement therapy for end-stage renal disease (ESRD) patients. Thus far, evidence for the initiation dosage of PD treatment is lacking, most patients begin their PD with four 2 L exchanges per day. However, many patients have their residual renal function at the initiation of PD, an 8 L dialysate per day will enhance the toxicity of bioincompatible dialysate and increase the economic burden compared with that of 6 L dialysate per day. Thus, the investigators perform a prospective, randomized, controlled, multi-center clinical study. The patients initiation of PD treatment within 6 months are randomized to be assigned to two groups: 6 L of dialysate per day and 8 L of dialysate per day, follow up will be regularly performed until 96 weeks. Clinical outcomes such as mortality, complications and life quality between the two groups will be investigated.

To investigate the effect, feasibility and safety of 6L of dialysate per day after initiation of peritoneal dialysis (PD), we perform a prospective, randomized, controlled, multi-center clinical study. The patients initiation of PD treatment within 6 months are randomized to be assigned to two groups: 6L of dialysate per day and 8L of dialysate per day, follow up will be regularly performed at baseline, 4 weeks, 8 weeks, 12 weeks, 24 weeks, 36 weeks, 48 weeks, 60 weeks, 72 weeks, 84 weeks and 96 weeks. Serum biochemical parameters, Kt/V, residual renal function (RRF), life quality and cardiovascular test will be regularly recorded. Clinical outcomes such as mortality, technique failure, complications and life quality between the two groups will be investigated.

complications including cardiovascular disease, nutritional and inflammation status, calcium and phosphorus level, anemia and life quality
