Parasitosis intestinales en niños hospitalizados: distribución por edad y aspectos clínicos / Intestinal parasites in hospitalized children: age distribution and clinical aspects

RESUMEN

Objetivo: Estimar la prevalencia de enteroparásitos y su comportamiento por edades en niños ingresados durante un periodo de cinco meses (enero-mayo) en el hospital Pediátrico Universitario del Cerro, en La Habana, Cuba. Métodos: Se realizó un estudio observacional descriptivo de corte transversal en el que se recogieron tres muestras de heces para exámenes coproparasitológicos y datos de interés clínico y epidemiológico por cuestionarios. Resultados: Giardia lamblia fue el protozoo más frecuente (31,7%), especialmente en los servicios de Gastroenterología (p0,05). Conclusiones: Se recomienda la búsqueda sistemática de estos agentes parasitarios en los niños ingresados con diarreas, para un mejor conocimiento de las enteroparasitosis en la población pediátrica, y la implementación oportuna de medidas de control.

ABSTRACT

Objective: To estimate the prevalence of intestinal parasitic infections and their behavior according to age. Methods: Adescriptive cross sectional survey was carried out in admitted patients and three faecal samples were collected for each child and were examined by parasitological techniques. Clinical and epidemiological data were too collected with questionnaires. Results: Giardia lamblia was the most frequent parasite isolated (31,7%), in special in diarrhea wards (p<0.05). Parasitic and commensal infections increased with age (p<0.01); and children aged more than five years showed the higher percentages (45,6%) (p<0.01). G. lamblia and Blastocystis spp. were found with a major frequency in preschool and school children; while Cryptosporidium spp. was found only in preschoolers. Abdominal pain was found in higher frequency in children infected with parasites (p<0,01), followed by anal itching, antecedents of shedding parasites (p<0,01), and anorexia (p<0,05). No statistical differences were found with the rest of symptoms. Conclusions: The systematic searching of these parasitic agents is recommended in children admitted with diarrhea, and this action would increase the knowledge of parasitic infections in our pediatric population and the implementation of opportune measures for the control.
