Abstract

Introduction: Peritoneal dialysis (PD) is an established treatment for patients with end-srage kidney disease. The method was developed as an alternative to hemodialysis (HD) presenting a patient survival rate equivalent to HD and better preservation of residual renal function. Peritoneal dialysis (PD) patients have different peritoneal membrane permeability (transport) characteristics. High peritoneal membrane permeability is associated with increased mortality risk in the patient population. Aim: The aim of this study was to analyze the importance of the peritoneal membrane transport status in patients treated with continuous ambulatory peritoneal dialysis (CAPD). Methods: The study included 60 adult continuous ambulatory peritoneal dialysis (CAPD) patients, 29 male and 31 female, mean age 56.63±15.06 years. All patients treated with conventional glucose- based PD fluids. For the short term (within 3 month after start of PD) and long term (more than 12 months) peritoneal dialysis analysis of peritoneal transport characteristics has been used peritoneal functional test (PFT). With the test, categorisation of patients was possible into high (H), high-average (HA), low average (LA), and low (L) transporters. Results: Dialysate–to plasma ratio (D/P) of creatinine showed significantly increased over time (0.654±0.141 vs... 0.705±0.13, p
