The pooled estimate of efficacy of lactobacillus rhamnosus GG and other probiotics significantly reduced the duration of diarrhea .
In conclusion , probiotics exert positive effect in reducing the duration of acute rotavirus diarrhea  compared with control
BACKGROUND Probiotic therapies with different strains demonstrated some beneficial effects , although some studies did not show any significant effects .
This study assessed systematic ally the current knowledge on the effect of probiotic bacteria on duration of  acute rotavirus diarrhea in children compared with control .
Limitations of Probiotic Therapy in Acute, Severe Dehydrating Diarrhea
Background Recent studies have shown that probiotics , most commonly Lactobacillus GG , may be useful in treating acute gastroenteritis . However , beneficial effects appear to be limited to a modest decrease in the duration of diarrhea . No studies have evaluated this therapy in moderate to severe dehydrating diarrhea in a metabolic facility . Methods Male children less than 2 years of age were admitted to a metabolic unit of the Department of Pediatrics at the Federal University of Bahia , Brazil , with moderate dehydration and were r and omized in a double-blind , placebo-controlled fashion . Oral rehydration solution ( ORS ) was administered per protocol and either placebo or Lactobacillus GG was given in combination with the ORS .  Output of urine , stool , and vomitus was recorded along with stool weight , nude body weight , and st and ard laboratory assessment s for hydration . Results There was no significant reduction in diarrhea duration and stool output in the Lactobacillus GG group . However , Kaplan-Meier survival analysis demonstrated that , even in moderate to severe diarrhea , resolution of the illness occurred so rapidly , that statistically significant benefits of probiotic therapy could not be demonstrated . Conclusion Our data implies that colonization must occur before benefits of probiotics can be realized . Probiotics are , therefore , likely to be of limited benefit in treating diarrheal illnesses of short duration such as viral enteritis . The beneficial effects of probiotics may be limited to prophylactic usage in high-risk population
