Abstract

Objective · To investigate the clinical characteristics of initial peritoneal dialysis (PD) patients with different peritoneal transport status, and analyze risk factors of high peritoneal transport status in PD patients.  Methods · A total of 455 consecutive PD patients newly starting PD between January 2007 to October 2015 were retrospectively analyzed. According to the results of the first sPET, patients were divided into H/HA (4h D/Pcr≥0.65) and L/ LA (4h D/Pcr<0.65) groups. Clinical and biochemical characteristics between the two groups were compared. Multivariate logistic regression model was established to investigate risk factors of higher peritoneal transport status of incident PD patients.  Results · The study included 372 incident PD patients. The L/LA group and H/HA group had 264 cases (71.2%) and 108 cases (28.8%) respectively. The H/HA group had higher proportion of male patients (63.0% vs 50.8%, P=0.03), lower residual renal function [RRF, (4.26±2.77) mL/min vs (5.79±4.53) mL/min, P<0.01], lower serum albumin level [(29.34±6.89) g/L vs (32.08±5.86) g/L, P=0.00], and more frequent diabetic nephropathy (19.4% vs 9.5%, P=0.00), compared with L/LA group. Univariate and multivariate logistic regression analysis showed that higher peritoneal transport status was associated with lower serum albumin level (OR=0.96, 95% CI 0.28-0.99; P=0.02), male (OR=1.92, 95% CI 1.19-3.12; P=0.00), presence of diabetic nephropathy (OR=2.52, 95% CI 1.26-5.05; P=0.00) and lower residual renal function (OR=0.90, 95% CI 0.83-0.96; P=0.00). The level of hsCRP in patients with hypoalbuminemia was higher than that in patients with normal albumin level (1.69 mg/L vs 0.69 mg/L, P=0.00).  Conclusion · Low and low average peritoneal transport status accounted for the majority of the patients in this study. Low serum albumin levels, male, diabetic nephropathy, RRF were risk factors of initial high peritoneal solute transport status. Chronic inflammatory status might partially explain for the correlation between hypoalbuminemia and high peritoneal solute transport status in PD patients.
