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 .
Efficacy of Lactobacillus GG in prevention of nosocomial diarrhea in infants.
OBJECTIVE Nosocomial diarrhea is a major problem in pediatric hospitals worldwide . We evaluated the efficacy of orally administered Lactobacillus GG ( LGG ) in the prevention of this disease in young children . STUDY DESIGN Eighty-one children aged 1 to 36 months who were hospitalized for reasons other than diarrhea were enrolled in a double-blind trial and r and omly assigned at admission to receive LGG ( n = 45 ) at a dose of 6 x 10(9 ) colony-forming units or a comparable placebo ( n = 36 ) twice daily orally for the duration of their hospital stay . RESULTS LGG reduced the risk of nosocomial diarrhea ( > or =3 loose or watery stools/24 h ) in comparison with placebo ( 6.7 % vs 33.3 % ; relative risk : 0.2 ; [ 95 % CI : 0.06 - 0.6 ] ; number needed to treat : 4 [ 95 % CI : 2 - 10 ] ) . The prevalence of rotavirus infection was similar in LGG and placebo groups ( 20 % vs 27.8 % , respectively ; relative risk : 0.72 ; 95 % CI : 0.33 - 1.56 ) . However , the use of LGG compared with placebo significantly reduced the risk of rotavirus gastroenteritis ( 1/45 [ 2.2 % ] vs 6/36 [ 16.7 % ] , respectively ; relative risk : 0.13 ; 95 % CI : 0.02 - 0.79 ; number needed to treat : 7 ; 95 % CI : 3 - 40 ) . CONCLUSIONS Prophylactic use of LGG significantly reduced the risk of nosocomial diarrhea in infants , particularly nosocomial rotavirus gastroenteritis
