Oral Zinc for the Treatment of Acute Diarrhea in US Children

Study Summary

Diarrheal diseases are the third leading cause of mortality in the world, with nearly 2 million deaths annually among children under age 5 years. Several clinical trials of oral zinc supplementation performed in developing country populations have confirmed this nutrient's efficacy in reducing the severity and frequency of diarrhea. The World Health Organization (WHO) has recommended global use of zinc supplementation in all children with diarrhea despite little or no data from trials in industrialized/developed settings. In the United States over 4 million children suffer annually from diarrheal illness. Although mortality is not a significant factor in U.S. cases, 75% of all cases present to medical care resulting in over 200,000 hospitalizations annually for diarrhea. This has significant impact on U.S. healthcare costs, with an average of $391 per outpatient treatment and $2,549 per inpatient treatment spent on each episode of acute diarrheal illness. The goal of this study is to evaluate the effectiveness of oral zinc in decreasing the duration of diarrhea in children treated as outpatients and in decreasing the duration of hospitalization in children treated as inpatients in an industrialized country. The results of this study promise to have a substantial impact on the management of a common pediatric health problem, and could conceivably affect direct and indirect healthcare costs to society.

Primary Outcome

Patients symptoms will be assessed to identify the duration of diarrhea between zinc and placebo groups before it becomes chronic diarrhea which by definition lasts longer than 14 days. Outcome of all patients in study will be assessed at study conclusion.

Interventions
