Abstract
The severity of diarrhea and nutritional status were measured in a prospective study of 97 patients hospitalized with cholera in Dacca, Bangladesh. Ninety-five percent of both adults and children were below their respective medians in weight as related to height; <15% of each group showed second-degree protein-calorie malnutrition. Duration of diarrhea, but not volume of stool per hour, was prolonged by 30%–70% in those adults and children suffering from more severe malnutrition. The increased stool loss was unrelated to antibiotic usage, to presence of intestinal parasites, or to the refeeding diet given. It is suggested that the prolongation of diarrhea represents the continued effect of cholera toxin that is irreversibly bound to intestinal mucosal cells, the replacement of which would be retarded under conditions of poor nutrition.
