Lactobacillus GG and acute diarrhoea in young children in the tropics.
A prospect i ve , placebo controlled , triple blind clinical trial was undertaken in Thail and to determine the effect of Lactobacillus GG on recovery from acute diarrhoea in children . Thirty-nine children ( mean age = 8 months ) were enrolled and following rehydration received either oral Lactobacillus GG ( n = 20 ) as a freeze-dried preparation or placebo ( n = 19 ) twice daily for 2 days . The clinical characteristics of the study groups were similar . There was no significant difference overall in clinical response detected between the study groups . When only those with acute non-bloody diarrhoea ( n = 26 ) were considered , the mean duration of diarrhoea was significantly shorter in the lactobacillus group ( 1.9 days ) than in the placebo group ( 3.3 days ) ( P < 0.055 ) . Stool frequency was less on the second day in the lactobacillus group ( P < 0.05 ) . The results suggest that Lactobacillus GG accelerates  recovery  from acute watery diarrhoea in young children in a tropical setting
