Abstract:
Objective To observe the long dwell ultrafiltration volume after using 7.5% icodextrin in different peritoneal transport characteristics of peritoneal dialysis patients. Methods Subgroup analysis of a perspective multicenter randomized double blind and parallel control study was performed. Continuous ambulatory peritoneal dialysis (CAPD) patients were divided into high transport (H) group, high-average transport (HA) group, low-average transport (LA) group and low transport (L) group according to D/Pcr and Twardoski standard. Ultrafiltration volume of night long dwell dialysate was calculated before and after clinic trial for 2 weeks and 4 weeks to evaluate the different effect of transporters on ultrafiltration volume. Results A total of 201 CAPD patients were enrolled in the study, including 98 patients in icodextrin group (ICO group) and 103 patients in glucose group (GLU group). Male and female cases were 96 and 105 respectively. Age was (56.1±13.7) years old (range from 18 to 81). One hundred and ninety-eight patients finished peritoneal equilibrium test (PET), including 24 (12.1%) of H, 72(36.2%)of HA, 81(40.7%)of LA,and 21 (11.0%)of L. After follow-up for four weeks, the ultrafiltration volume was much higher than baseline in H, HA and LA groups. Also ultrafiltration volume in icodextrin group was much higher than that in glucose-based dialysate. Howerve, the increased volume was not significantly difference in L group. Ultrafiltration volume of icodextrin was positively correlated to D/Pcr (R2=0.1681,P＜0.01), while ultratration volume of dextrose was negatively correlated to D/Pcr (R2=0.0949,P＜0.01). Conclusion Compare to glucose-based dialysate (Dineal), 7.5% icodextrin dialysate (Extraneal) improves the ultrafiltration and peritoneal creatinine clearance of long dwell notabily in H, HA and LA group.
