The efficacy of each probiotic should be evaluated separately.
Previously it was shown that Lactobacillus GG is effective in treating acute gastroenteritis in children.
Dr Szajewska and colleagues from Poland updated their 2007 meta-analysis on the effectiveness of Lactobacillus GG in treating acute gastroenteritis in children.
The Cochrane Library, MEDLINE and EMBASE databases were searched from 2006 to 2013, with no language restrictions, for randomized controlled trials and meta-analyses.
The team reported that 15 randomized controlled trials met the inclusion criteria in this updated meta-analysis.
The researchers combined data from 11 randomized controlled trials, and showed that Lactobacillus GG significantly reduced the duration of diarrhoea compared with placebo or no treatment.
Lactobacillus GG was more effective when used at a daily dose =1010 CFU than when used at a daily dose <1010 CFU.

Lactobacillus GG was effective in children treated in Europe.
The team observed that in the non-European setting, the difference between the Lactobacillus GG group and the control group was of a borderline statistical significance.
Dr Szajewska's team concludes, "Lactobacillus GG reduces the duration of diarrhea."
"A subset of patients that is more likely to benefit includes subjects treated with a high daily dose of Lactobacillus GG who are either in-patients or out-patients from geographical Europe."
"Given the methodological limitations of many of the included trials, the evidence should be viewed with caution."
