AbstractsOther managements were similar in all groups. Stool weight(g) and duration of diarrhea were the primary outcomes. Results There was a trend in stool weight reduction in the groups receiving L-isoleucine and the reduction was significant on day 2 (mean ± SD, L-isoleucine vs. vit D vs. L -isoleucine + vit D vs. control, 276±228 vs. 386±302 vs. 301± 181 vs. 447± 325, p=0.039) and day3 (176±157 vs. 321±273 vs. 276±169 vs. 341±292, p=0.045). The duration of diarrhea was similar in all groups. Conclusion L-isoleucine supplemented food reduces stool weight in children with acute diarrhea.
