Description
OBJETIVO: describir los microorganismos más frecuentes reportados en los cultivos de líquido peritoneal en pacientes con peritonitis que se encuentran en el programa de diálisis peritoneal continua ambulatoria.
PACIENTES Y MÉTODOS: diseño observacional, transversal, descriptivo. Pacientes inscritos al programa de diálisis peritoneal continua ambulatoria que sean hospitalizados con diagnóstico de peritonitis durante el período comprendido entre el 14 de noviembre de 2006 al 14 de mayo de 2007 en el Hospital General de Zona N° 2 del Instituto Mexicano del Seguro Social.
VARIABLES INCLUIDAS: sexo, edad, período entre el último período de peritonitis y el actual, número de episodios previos de peritonitis, pH del líquido peritoneal, número de células en el citológico de líquido peritoneal, y microorganismo identificado en el cultivo. Se estimaron estadísticas descriptivas con 95% de confianza (p=0.05).
RESULTADOS: Se obtuvieron 24 pacientes con peritonitis, 15 masculinos (62,5%) y 9 femeninos (37,5%), sin diferencia significativa, media de edad 50 años, desviación estándar +/- 14 años, de los cuales, 11 pacientes (45,8%) correspondían al primer episodio y 13 pacientes (54,2%) con antecedentes de peritonitis previas, la media de episodios previos de peritonitis fue 3 con desviación estándar +/- 2. 15 cultivos fueron negativos (62,5%) y 9 positivos (37,5%). Los microorganismos identificados fueron Candida albicans 44,4%, Escherichia coli 33,3% y Staphylococcus aureus 22,2%.
CONCLUSIONES: Los sujetos de estudio presentan peritonitis con mayor frecuencia que lo reportado por la literatura. Los microorganismos identificados en esta serie se presentaron con una frecuencia diferente a la reportada por otros autores, Candida albicans fue el más frecuente. Se recomienda realizar series futuras, preferiblemente estudios de cohorte, con muestras de líquido peritoneal sin antibióticos.

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.
