ABSTRACT

A prospective study was performed on 20 bacteriologically proven pediatric cases of severe shigellosis admitted to the Department of Pediatrics, Chulalongkorn Hospital during March 1989 to March 1990. Fourteen patients were male and six were female. Shigella B was found in 85% and Shigella D in 15% of cases. The major indications for admission were convulsions and dehydration. Fifteen per cent of cases had underlying malignancies and 42.1% had malnutrition. Most patients had a peak of fever between 39.5 and 40.5 degrees C, serum sodium between 128-144 mEq/l. Mild acidosis was detected in 45% and moderate acidosis in 30% of cases. There were no statistical differences in peak of fever and serum sodium between patients who had convulsion and who did not. Shigellemia was found in one case who also had underlying neuroblastoma. One patient died due to necrotizing enterocolitis, septic shock and renal failure. Most of the organisms found resisted to ampicillin and trimethoprim-sulfamethoxazole (TMP-SMX). However, TMP-SMX was prescribed in most immunocompetent patients and they recovered well. All of three patients with underlying malignancy responded well to ceftriaxone.

ABSTRACT

Se define como shigelosis a la enfermedad intestinal producida por las diferentes especies del género Shigella, de las cuales el humano es el principal hospedero. Shigella es un bacilo corto, Gram-negativo, de la familia Enterobacteriaceae. La shigelosis se manifiesta en tres formas: 1) disentería clásica (sangre, moco, pus), 2) diarrea acuosa no complicada y 3) una combinación de disentería y diarrea acuosa. La mayoría de los casos de diarrea acuosa no son distinguibles de las que son ocacionadas por otras etiologías. Concluye el documento enfatizando que, no existe hasta el momento actual ninguna vacuna contra Shigella que pueda ser recomendable para la aplicación en población general. Todos los esfuerzos hasta ahora realizados han quedado en pequeños estudios en voluntarios, en los cuales se han obtenido fracasos y en otros ensayos se han vislumbrado posibles vacunas para emplear en el futuro. Dentro de los modelos experimentales de vacunas que hasta el momento hay, se está intentando corregir los posibles errores y por otra parte conjuntar los mecanismos de acción propuestos para cada tipo de vacuna. Finalmente si la shigelosis es un problema de salud pública, principalmente en los países en vías de desarrollo, son importantes los esfuerzos para lograr obtener una vacuna que en lo futuro pueda reducir uno de los principales problemas de morbilidad infantil
