Comparison of Efficacy Between Nighttime and Daytime Peritoneal Dialysis

Sponsor: Nanfang Hospital, Southern Medical University

Summary

Background: Compared with continuous ambulatory peritoneal dialysis (CAPD), nocturnal continuous cyclic peritoneal dialysis (NCPD) uses a machine to exchange fluid to perform dialysis at night, allowing patients to work or study normally during daytime. Since the dialysis fluid retention time of NCPD patients is shorter than that of CAPD, this RCT was designed to investigate whether there is a difference in the efficacy between the two modalities on peritoneal dialysis. Design: Randomized, open-label, cross-over, multi-center clinical trial. Objective: Primary Objective: To compare the adequacy of peritoneal dialysis between NCPD and CAPD in non-diabetic patients. Secondary Objective: To compare the effects of NCPD and CAPD on the quality of life, including sleep quality, nocturnal blood pressure, and ultra-filtration volume in non-diabetic patients. Hypothesis: In non-diabetic patients, NCDP is non-inferior to CAPD in peritoneal dialysis adequacy. Methods: A total of 124 non-diabetic peritoneal dialysis patients will be enrolled and randomly assgined into two groups in a 1:1 ratio. Patients in group A will receive NCPD treatment from 1 to 12 weeks and then switch to CAPD treatment from 13 to 24 weeks, while patients in group B will receive CAPD treatment from 1 to 12 weeks and then switch to NCPD treatment from 13 to 24 weeks. All patients are required to sign an informed consent before enrollment. The enrolled patients are planned to be followed every 4 weeks, and unplanned visits will be arranged if necessary. The peritoneal dialysis adequacy (weekly total Kt/V) of the patients will be assessed at baseline and at the corresponding visit points. The average daily ultra-filtration volume during the two modalities of treatment will be compared. Sleep quality parameters will be collected using a contact-free continuous vital signs monitoring equipment at baseline, Week 12 and Week 24. The health-related quality of life and social function will be analyzed using the Kidney Disease Quality of Life 36-item short form survey (KDQOL-36) and Social Disability Screening Schedule (SDSS) questionnaire. Twenty-four-hour Ambulatory Blood Pressure (ABP) will be monitored at baseline, Week 12, and Week 24.
