Estudo etiológico da diarréia em crianças hospitalizadas no Instituto Materno Infantil Prof. Fernando Figueira, IMIP, em Recife, Pernambuco

Abstract

Objectives: to identify enteropathogens in the stools of children hospitalized with diarrhea. Methods: case series studies, comprising 36 children aged between zero and 60 months old with diarrhea hospitalized in the Instituto Materno Infantil Prof. Fernando Figueira, IMIP, between January and May, 2005. Social and demographic variables were collected, mothers'characteristics and diarrhea episode. Etiological research used stools culture and serologic tests. Results: the majority of the children (80.5%) were under 12 months old. Families had very poor social and economic conditions and 83.4% had per capita incomes under half a minimum salary per month. As for the microorganisms detected in stools culture, classis enteropathogenic E.coli (EPEC) appeared in 8.4% of the cases with no growth of Salmonella sp. or Shiguella sp. and Klebsiella sp. ESBL + was isolated in 33.3% of the patients. Klebisiellas demonstrated a high resistance profile in the antibiogram, compatible with hospital strains catalogued by the institution. Conclusions: the study presented a low enteropathogenic bacteria recovery rate but revealed a prevalent mutiresistant Klebsiella strain with important nosocomial infection risk implications and diarrhea persistence.
