Impact of AHCC® Supplementation for Prevention of Respiratory Tract Infections Among Children Age 4-6 Years Old

Официальное название

A Double-Blind, Randomized, Placebo-Controlled Trial of AHCC® Supplementation for Prevention of Respiratory Tract Infections Among Children Age 4-6 Years Old

Обзор

This is a study to evaluate the effects of a prebiotic, AHCC, a standardized extract of cultured Lentinula edodes mycelia, on immunologic markers and the incidence of respiratory tract infections in children.

Подробное описание

A three-month, randomized, double-blind, placebo-controlled, pilot study will be performed in Indonesian healthy children aged 4 to 6 years in Nursery Schools. Subjects will be administered dextrin alone (placebo) or dextrin including AHCC. The incidence of RTI will be the primary outcome, and changes in serum Interferon Gamma (IFN-γ) as the crucial cytokine that acts as anti infective in the immune system will be the secondary outcome. Following completion of the 3 months intervention, participants will enter a 5 months follow up period (Months 4-8). New onset adverse events, ongoing adverse events, serious adverse events, and investigator assessed intervention related adverse events will be collected and evaluated.
