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 .
A human Lactobacillus strain (Lactobacillus casei sp strain GG) promotes recovery from acute diarrhea in children.
To determine the effect of a human Lactobacillus strain  ( Lactobacillus casei sp strain GG , Gefilac ) on  recovery from acute diarrhea ( 82 % rotavirus ) , 71 well-nourished children between 4 and 45 months of age were studied . After oral rehydration , the patients r and omly received either Lactobacillus GG-fermented milk product , 125 g ( 10(10 - 11 ) colony-forming units ) twice daily ( group 1 ) ; Lactobacillus GG freeze-dried powder , one dose ( 10(10 - 11 ) colony-forming units ) twice daily ( group 2 ) ; or a placebo , a pasteurized yogurt ( group 3 ) 125 g twice daily ; each diet was given for 5 days , in addition to normal full diet otherwise free of fermented dairy products . The mean ( SD ) duration of diarrhea after commencing the therapy was significantly shorter in group 1 ( 1.4 [ 0.8 ] days ) and in group 2 ( 1.4 [ 0.8 ] days ) than in group 3 ( 2.4 [ 1.1 ] days ) ; F = 8.70 , P less than 0.001 . After rehydration , each dietary group maintained a positive weight trend . The urinary lactulose-mannitol recovery ratios ( means [ 95 % confidence intervals ] ) on admission were 0.09 ( 0.03 , 0.24 ) in group 1 , 0.12 ( 0.07 , 0.22 ) in group 2 , and 0.08 ( 0.04 , 0.18 ) in group 3 ; no significant alterations in intestinal permeability were observed at retesting after 2 days of realimentation . The result indicates that early nutritional repletion after rehydration causes no mucosal disruption and is beneficial for recovery from diarrhea . It is further suggested that Lactobacillus GG in the form of fermented milk or freeze-dried powder is effective in shortening the course of acute diarrhea
