Title: Extended Studies on Safety and Efficacy of Zinc-ORS Compared to ORS Alone in Hospitalized Children With Severe and Complicated Acute Diarrhea
Brief Summary: Three-hundred-and-fifty-two males aged 1-36 months with acute non-dysenteric diarrhoea and no systemic illness will be enrolled in this clinical trial. Eligible children will be stratified by their age (1up to 5 months, 6-35 months). Within the two age strata the patients will be randomized to receive zinc-ORS (fortified with 40 mg elemental zinc as zinc gluconate per litre) or standard WHO ORS. The major outcome measures will be stool output and duration of diarrhea. The safety of administering zinc will be determined by examining the effect of zinc ingestion on vomiting, sodium and potassium homeostasis, plasma zinc and copper, and iron stores and concentration of serum transferrin receptor.
