We prospectively studied clinical outcome and nutrition absorption in male children (6-36 months of age) with persistent diarrhea (PD) and severe protein-energy malnutrition (mean z score for age, -4.2 +/- 0.8). Fifty-one children were randomly allocated to receive a combination of khitchri, a rice-lentil mixture, yogurt, and half-strength buffalo milk (group A; n = 26) or full-strength soy formula (group B; n = 25) for 14 days. The initial caloric intake (p < 0.02) and mean weight gain (p < 0.02) were greater in the group B patients. The mean stool volume and frequency were comparable between the two groups. Seven children in group A were considered clinical failures by criteria of weight loss and PD, compared to three in group B. The coefficients of absorption (COA) for protein were similar between the two groups, but group B patients had higher values of COA for energy and fat (p < 0.05) in the second week of nutritional rehabilitation. The majority (63%) of the children improved on the khichri-yogurt-milk diet but the nutritional outcome was not as good as with the soy formula. These data indicate that a traditional diet can be successfully used in the dietary management of PD and severe malnutrition but that a more optimal composition, yielding a higher success rate, should be sought.

In a prospective study we randomized 102 male children (age 6-36 months) with persistent diarrhea to receive a traditional rice-lentil (Khitchri) diet and yogurt (K-Y) or a soy formula (alone for seven days and then in combination with K-Y for seven days). Of 73 children satisfying the study criteria, 66 were successfully treated and there were 7 treatment failures. There was poor concordance between parental accounts of severity of diarrhea or vomiting and that observed after admission. Significant risk factors associated with treatment failure included younger age (p < 0.005) and vomiting at presentation (p < 0.02). The greatest number of risk factors associated with delayed recovery (> 10 days) were identified during an initial evaluation period (the first 8 h after admission). These included greater severity of watery diarrhoea (p < 0.01) and increased ORS intake (p < 0.02). Our data suggest that an initial evaluation period, including objective observations, may identify children with persistent diarrhea who are at greatest need of hospitalization.
