[Therapeutic effects of zinc supplement as adjunctive therapy in infants and young children with rotavirus enteritis].

OBJECTIVE: To investigate the therapeutic effects of oral zinc supplement in infants and young children with rotavirus enteritis, and its preventive effects against diarrhea recurrence within 3 months after treatment. METHODS: A total of 103 infants and young children with rotavirus enteritis were randomly divided into zinc supplement group (n=51) and conventional treatment group (n=52). Both groups were equally treated with a comprehensive therapy, besides which the zinc supplement group received zinc gluconate granules for 10 days. The treatment outcomes were examined at 72 hours after treatment, and the time required for the disappearance of positive symptoms and the recovery of injured extra-intestinal organs were determined. In addition, these patients were followed up for 3 months to determine the incidence of diarrhea recurrence after treatment. RESULTS: The overall response rate in the zinc supplement group was significantly higher than that in the conventional treatment group (90% vs 75%; P<0.05). The durations of diarrhea, high fever, and vomiting in the zinc supplement group were significantly shorter than that in the conventional treatment group (P<0.05). In addition, the recurrence rate of diarrhea and the incidence of severe diarrhea within 3 months after treatment in the zinc supplement group were significantly lower than in the conventional treatment group (P<0.05). CONCLUSIONS: Oral zinc supplement as adjunctive therapy is effective in treating infants and young children with rotavirus enteritis, and reducing the incidence and severity of diarrhea recurrence in the subsequent 3 months.
