Effect of carbohydrate composition of semi-elemental diets on the nutritional recovery of children with chronic diarrhea.

Abstract

46 of 74 children with chronic diarrhea of unknown etiology between the ages of 44-627 days were studies. They were assigned, by single randomization, to 3 dietary treatments: a) cow's milk, b) a sucrose- free (SED-S), and c) a sucrose containiNG semi-element diet (SED+S), for 15 days. The authors registered the daily increase of body weight, daily amount of ingested kcal, and the increase of body weight/1000 kcal. The number of days with diarrhea before hospitalization, the age and weight of each child before treatment were recorded and analyzed as covariates. Maltase, sucrase, and lactase activity values were compared before treatment, but were not different among the 3 groups. A significant increase of body weight/1000 kcal ingested was observed in children fed the SED-S diet compared to that observed in children on cow's milk (P=.013 in ANCOVA; P+.053 in RANCOVA), and those fed SED+S (P=.009 in Ancova; p.001 in RANCOVA). The covariates did not have any apparent effect on these results. Only 7 of 24 children receiving cow's milk completed the assigned diet. The carbohydrate composition of the semi-elemental diets proved to be fundamental in the nutritional recovery of these patients.
