Clinical efficacy of oral immunoglobulin Y in infant rotavirus enteritis: Systematic review and meta-analysis.

Abstract

Background:Rotavirus (RV) can cause vomiting and diarrhea in infants and children, and could be treated clinically with immunoglobulin Y (IgY), which is an immunoglobulin extracted from chicken yolk. There is no systematic evaluation of immunoglobulin in the treatment of rotavirus enteritis. Therefore, we systematically evaluated rotavirus enteritis with oral immunoglobulin Y therapy using meta-analysis.Methods:We conducted a systematic search in CNKI, WANFANG DATA, VIP, PubMed, and the Cochrane Library databases (up to April 30, 2018). Using Revman 5.3 software for meta-analysis.Results:A total of 2626 subjects with rotavirus diarrhea from 17 randomized clinical trials were included in the meta-analysis. Of these, 1347 subjects received oral immunoglobulin Y and 1279 subjects received conventional treatment. The results of the meta-analysis indicated that the total number of effective cases and effective rates of immunoglobulin Y in treatment of rotavirus enteritis in infants and children was statistically different from that in the control group (odds ratio [OR] = 3.87, 95% confidence interval [CI] (3.17, 4.74), P < .00001) and (OR = 3.63, 95% CI [2.75, 4.80], P < .00001).Conclusions:Immunoglobulin Y is effective in the treatment of infantile rotavirus enteritis. Oral immunoglobulin Y can be widely used in the treatment of rotavirus enteritis in clinic.
