{diamondsuit} Objectives: To evaluate patient and technique survival and to provide an analysis of peritoneal dialysis (PD)-related peritonitis in 25 years of experience in a single center.

{diamondsuit} Study Design: Retrospective study of incident patients on PD from July 1980 to July 2005.

{diamondsuit} Setting: Single, university based, Brazilian dialysis program.

{diamondsuit} Patients: 680 patients were analyzed in our study from July 1980 to July 2005, with a cumulative experience of 15 303 patient-months. All patients over 15 years of age entering the dialysis program were included in the study. Patients with less than 30 days of follow-up were excluded. Biochemical and demographic variables, peritonitis episodes, and patient and technique survival were analyzed.

{diamondsuit} Results: Mean age at start of PD was 53 ± 16 years; diabetic nephropathy was the main cause of chronic kidney disease. Cardiovascular disease was the main cause of death (44%); peritonitis was responsible for 16% of fatal events. The predictors of death in our study were diabetes [relative risk (RR) 1.23, p < 0.01], advanced age (RR 1.58, p < 0.001), low serum albumin level (RR 1.25, p < 0.01), and low serum phosphate level (RR 1.39, p < 0.001) upon starting PD. There were 1048 cases of peritonitis over the 25-year period, with a significant reduction in incidence after the introduction of the double-bag system. The number of incident PD patients originating from hemodialysis increased threefold over the observation period (p < 0.001), with a similar increase in comorbidities over time.

{diamondsuit} Conclusion: In the largest single-center report of PD experience in Latin America, we describe the overall rate and trends over time of peritonitis as well as patient and technique survival, which are similar to previous reports. Significant changes in peritonitis rates and causative organisms as well as a significant time-dependent increase in high-risk patients starting PD were observed.
