Background:Recently, evidence from a large randomised controlled trial (RCT) negated efficacy of Lactobacillus rhamnosus GG for treating acute gastroenteritis in children.Aim: To review RCTs in which L rhamnosus GG was used to treat acute gastroenteritis in children.
Methods:The Cochrane Library, MEDLINE, and EMBASE databases were searched from May 2013 (end of last search) to January 2019. The primary outcomes were stool volume and duration of diarrhoea.Results: Eighteen RCTs (n = 4208) were included. Compared with placebo or no treatment, L rhamnosus GG use had no effect on stool volume but was associated with a reduced duration of diarrhoea (15 RCTs, n = 3820, mean difference, MD −0.85 day, 95% CI −1.15 to −0.56). L rhamnosus GG was effective when used at a daily dose of ≥10 10 CFU or <10 10 CFU; however, the latter produced results of borderline significance. L rhamnosus GG was more effective when used in European countries compared with non-European countries, particularly when considered by region.L rhamnosus GG use was associated with a reduced duration of hospitalisation. One RCT found that L rhamnosus GG had no effect on the total clinical severity score at 14 days after enrolment.
Conclusions:Despite a recent large RCT demonstrating no effect of L rhamnosus GG, current evidence shows that, overall, L rhamnosus GG reduced both the duration of diarrhoea (with a higher impact in European countries) and hospitalisation in inpatients. These findings should be viewed in the context of the high heterogeneity and methodological limitations of the included trials.
