Abstract:

The purpose of this review article is to evaluate clinical data indicating the benefits of oral zinc supplementation to prevent andor treat diarrhea in children and extend these findings to adults. Zinc plays an important role in modulating host resistance to infectious agents and reducing the risk, severity, and duration of diarrheal diseases. Zinc is important in the developing world and in low-income and middle-income countries where mild-to-moderate zinc deficiency is highly prevalent. The WHOUNICEF recommendations for zinc supplementation are based on meta-analyses of randomized, controlled intervention trials on children 20 mg zincday for 10-14 days for children with acute diarrhea and 10 mgday for infants under 6 months of age. Effective forms include sulfate, gluconate, or acetate, No similar studies have been conducted on adults. Thus, carefully conducted clinical trials are necessary to ascertain the efficacy of zinc in the prevention of acute and persistent diarrhea in adults. Faced with rising antibiotic resistance and the lack of effective antidiarrheal vaccines, oral zinc provides substantial benefit in the reduction of stool output and disease duration combined with safety, selectivity of action, and low cost. Thus, oral zinc supplementation is a practical therapeutic intervention for the treatment of diarrhea in children, and by extension, should be provided to adults.
