Abstract
OBJECTIVE: Describe the most frequent microorganisms reported in the cultivations of peritoneal liquid in patient with peritonitis that are in the program of Continuous Ambulatory Peritoneal Dialysis.
PATIENTS AND METHODS: observational, traverse, descriptive design. Patients inscribed to the program of Continuous Ambulatory Peritoneal Dialysis that they are hospitalized with peritonitis diagnosis in the Hospital General de Zona Number 2 of the Instituto Mexicano del Seguro Social. Period november 14, 2006 at the may 14, 2007.
INCLUDED VARIABLES: sex, age, period between the last period of peritonitis and the current one, number of previous episodes of peritonitis, pH of the peritoneal liquid, number of cells in the cytological of peritoneal liquid, and microorganism identified in the cultivation. They were estimated descriptive statistical with 95% of confiance (p=0.05).
RESULTS: 24 patients with peritonitis, 15 male (62,5%) and 9 female (37,5%), without significant difference. Medial age 50 +14 years. 11 patients (45,8%) of first time, 13 patients (54,2%) with antecedents of previous peritonitis. Medial of previous episodes of peritonitis 3 +2. 15 negative cultivations (62,5%) and 9 positive (37,5%). Identified microorganisms Candida albicans 44,4%, Escherichia coli 33,3% and Staphylococcus aureus 22,2%.
CONCLUSIONS: The subject of study present peritonitis with more frequency than those reported by the literature. The microorganisms identified in this series were presented with a frequency different to the one reported by other authors, Candida albicans was the most frequent. It be recommended carry out future series, preferably cohort studies, with peritoneal liquid samples without antibiotics.
Keywords: Peritoneal dialysis. Peritonitis. Causal microorganism.
