ABSTRACT

Background: Ideal empiric treatment for peritonitis associated with continuous ambulatory peritoneal dialysis should be as effective as possible, without favoring the increase of methicillin-resistant Staphylococcus aureus and cover most common etiologic germs found at each hospital. Objective: To identify the most common etiologic agent of peritonitis associated with continuous ambulatory peritoneal dialysis in our emergency unit in the last five years. Methods: Review of medical records of patients with the diagnosis of dialysis-associated peritonitis admitted to the adult emergency department in the last five years and describe the most common etiologic agent. Results: The study included 149 patients. The causative agents were distributed as follows: 77 cases Gram positive representing 51.7%; Gram negative 60 cases representing 40.3%; fungi were isolated in 12 patients representing 8.1% of cases. Among the Gram positive Staphylococcus aureus was the most frequently isolated in 40 cases, representing 51.9% of Gram positive. Conclusions: In our hospital the most common causative germ is Staphylococcus aureus, being methicillin resistant in 18%, so empirical use of vancomycin is justified. Cases caused by Gram negative germs have been increasing worldwide, being severe and difficult to eradicate.
