Evaluation of Continuous Ambulatory Peritoneal Dialysis-Related Peritonitis Episodes

Abstract

OBJECTIVE: The aim of this study was to determine the incidence of peritonitis in patients with continuous ambulatory peritoneal dialysis (CAPD)-related peritonitis, microorganisms causing peritonitis and the clinical course of patients during the 15-year study period. MATERIAL and METHODS: A total of 61 patients (26 male, 35 female) with CAPD-related peritonitis treated in our hospital between 2000-2014 were enrolled into this study. RESULTS: During the study period, 103 episodes of peritonitis were observed, with a mean incidence of 0.29 episodes per patient year. Overall, 58.3% of the episodes were due to gram-positive organisms, 7.8% due to gram-negative organisms and 30.1% were culture negative. The treatment was successful in 96.1% of the episodes, and removal of the Tenckhoff catheter was required in 4 patients. It was observed when the distribution of the causative organisms over the years were examined that the number of CAPD peritonitis and the rate of culture-negative episodes decreased after the year 2008. CONCLUSION: In our center, the main causes of peritonitis were gram-positive microorganisms. During follow-up, the incidence of peritonitis and the rate of culture-negative episodes decreased but there was no change in the gram stain characteristics of organisms. Reducing the incidence of CAPD-related peritonitis could be possible by providing intensive training to patients and strict monitoring.
