Risk Factors for Peritonitis in a Pediatric Dialysis Program in Guatemala, 2011–2014

Abstract

Background. Peritonitis is the most common complication of peritoneal dialysis but there is limited data regarding peritonitis related risk factors in developing countries. Objective. Describe the PD program at Foundation for Children with Kidney Disease (FUNDANIER), in Guatemala, and identify peritonitis related risk factors in these patients. Methods. This retrospective open cohort study included medical records from FUNDANIER during 2011 to 2014. Baseline demographics, treatment modalities, caregivers’ characteristics, and socioeconomic status were recorded. Results. Eighty-nine medical records were included with a treatment time of 1855 months. Median age of patients was 11.3 years (range 6–17). Median duration of PD therapy was 20.8 months (range 1–28). Sixty-eight peritonitis episodes were registered; forty-eight patients (54%) remained peritonitis-free. Median time to first peritonitis episode was 5 months (range 2–16). Peritonitis rate was one episode every 27 months or 0.44 episodes per patient-year. Peritonitis rate in patients with fair housing was 2.5 times higher than in those with good housing (CI = 1.0–5.2, p=0.01). Conclusion. Housing conditions are a relevant risk factor related to peritonitis. Strategies toward preventing peritonitis must consider housing status, establishing adequate follow-up in high-risk patients. Close monitoring of technique serves to overcome understaffing issues in this setting.
