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 .
Lactobacillus paracasei Strain ST11 Has No Effect on Rotavirus but Ameliorates the Outcome of Nonrotavirus Diarrhea in Children From Bangladesh
Background . Previous studies have shown that selected strains of lactobacilli that are administered orally result in a modest reduction of diarrhea duration . However , duration alone is not considered optimal for therapeutic evaluation of any agent in diarrhea . Objective . To examine the effect of a new probiotic , Lactobacillus paracasei strain ST11 ( ST11 ) , in acute childhood diarrhea by using evaluation criteria recommended by the World Health Organization . Methods . In a r and omized , double-blind , placebo-controlled clinical trial , 230 male infants and young children , 4 to 24 months of age , presenting with diarrhea of < 2 days ' duration were admitted to the metabolic research ward of the International Centre for Diarrheal Disease Research , Bangladesh , and fed 1010 colony-forming units of lyophilized ST11 or placebo daily for 5 days . Stool output and frequency , oral rehydration solution intake , and excretion of rotavirus were monitored daily . Results . No effect of ST11 treatment on severe rotavirus diarrhea was observed . However , the probiotic treatment did significantly reduce cumulative stool output ( 225 ± 218 vs 381 ± 240 mL/kg ) , stool frequency ( 27.9 ± 17 vs 42.5 ± 26 ) , and oral rehydration solution intake ( 180 ± 207 vs 331 ± 236 mL/kg ) in children with less-severe nonrotavirus diarrhea compared with those receiving placebo treatment . A significantly higher proportion of nonrotavirus children receiving ST11 had their diarrhea resolve within 6 days of therapy ( ST11 versus placebo : 76 % vs 49 % ) . Conclusions . ST11 has a clinical ly significant benefit in the management of children with nonrotavirus-induced diarrhea , but it is ineffective in those with rotavirus diarrhea
