Background
Peritonitis is a major cause of morbidity, mortality and increase health care cost in patients on peritoneal dialysis (PD). PD infection is associated with peritoneal membrane loss, technique failure and mortality. Following an episode of peritonitis, the risk of more peritonitis episodes, hemodialysis switch and death increased during the first month and during the next 6 months.
Methods
We evaluated retrospectively all patients with peritonitis episode from October 2014 to December 2016 in the “National Institute of Cardiology Ignacio Chávez” in Mexico City on different PD modalities: Continuous Ambulatory Peritoneal Dialysis (CAPD) and automated peritoneal dialysis (APD).
Results
71 patients were evaluated, 36 (50.7%) of female sex with a median age of 50 years. 54 (76.1%) on CAPD and 17 (23.9%) on APD. The main cause of renal failure were diabetic nephropathy in 34 patients (45.1%).On 28 patients (39.4%)no history of peritonitis and the comorbidities were chronic hypertension (47.9%), ischemic heart disease (16.9%) and chronic heart failure (8.5%). The most frequent organism identified on cultures were S aureus in 23 (32.4%) patients, E coli in 7 (9.9%), S marcescens in 5 (7%), S epidermidis with 5 (7%) cases and Candida in 5 patients (7%).
Conclusion
The CAPD group presented more frequently peritonitis episodes.
Most frequent infection was gram positive organisms: S. aureus in 39.4%.
Mechanical dysfunction presented only in 1 patient of APD patients, and also only 1 patient died in this group.
The level of albumin and BUN demonstrated a statistical significance and are associated with worst outcome in all patients.
