ABSTRACT

Resumen El objetivo de nuestro estudio fue describir las características clínico-epidemiológicas de los pacientes pediátricos con diarrea por Aeromonas spp. y estudiar lasensibilidad antibiótica de dicho agente, a partir del análisis de casos ocurridos en un períodode 7 anos. Aeromonas caviae fue identificada en 93 muestras de heces recuperadas de ninos,el 52,2% de ellos fueron varones y el 85,6% menores de 36 meses. La estación del ano conmenor cantidad de aislamientos fue el invierno (14,4%). Hubo coinfección con otros microorganismos diarreogénicos en el 31,1% de esas muestras. El mayor número de muestras procediódel servicio de urgencias de nuestro hospital (45,6%). El 43,3% de los pacientes presentaronfiebre; el 87,8%, diarrea (43% con productos patológicos) y el 67,8%, vómitos. El 73,3% de lospacientes no precisó ingreso hospitalario. Se encontró una sensibilidad superior al 87% frentea trimetoprima-sulfametoxazol, ciprofloxacina, cefotaxima y cefepime. Todos los pacientessuperaron el proceso infeccioso aun cuando el 63,3% no recibió ningún tratamiento antibiótico.Concluimos que el tratamiento antibiótico estaría indicado en casos seleccionados, cuandoexiste gravedad clínica.© 2019 Asociacion Argentina de Microbiologıa.

Abstract The aim of our study was to describe the epidemiological features of pediatric patients with diarrhea caused by Aeromonas spp. and to study the antibiotic susceptibility of this agent during a seven-year period. Aeromonas caviae was identified in 93 stool samples from 52.2% males and 85.6% patients younger than 36 months. The season with the lowest number of isolates was winter (14.4%). Coinfection with other diarrheagenic microorganisms was observed in 31.1% of the cases. The largest number of isolates was obtained from Emergency Department samples (45.6%); 43.3% of the patients presented with fever, 87.8% with diarrhea (43% of these cases were associated with pathological products) and 67.8% with vomiting, while 73.3% of the patients did not require hospital admission. Susceptibility higher than 87% was observed to trimethoprim-sulfamethoxazole, ciprofloxacin, cefotaxime and cefepime. All the patients overcame the infectious process and 63.3% of them did not receive any antibiotic treat-ment during the process. A. caviae was the isolated species associated with intestinal infection. Antibiotic treatment would be specifically indicated in cases selected for their clinical severity. © 2019 Asociación Argentina de Microbiología. Published by Elsevier España, S.L.U.
