Association of malarial parasitaemia with dehydrating diarrhoea in Nigerian children.

Abstract

Records of 402 children--216 (53.7%) males and 186 (46.3%) females--aged 1-36 month(s), admitted to the Diarrhoea Treatment and Training Unit of the University of Benin Teaching Hospital, Benin city, Nigeria, during July 1993-June 1996, were reviewed to document the relationship between dehydration and malaria parasitaemia. There was a significant association between severity of dehydration and malaria parasitaemia (p < 0.0001). Association of parasitaemia (p < 0.006) with dehydration (p < 0.0001) was significantly more marked in patients with acute watery diarrhoea than in those with persistent and bloody diarrhoea. Parasitaemia was demonstrated in 50.5% of those not initially suspected to have malaria. Parasitaemia was also significantly associated with fever (p < 0.001) and fever coexisting with vomiting (p < 0.01). The prevalence of malaria-associated diarrhoea was 61.7%. More infants (75.6%) than older children had diarrhoea. It was concluded that the prevalence of malaria-associated diarrhoea was high and that children with dehydration are more likely to manifest malaria parasitaemia.
