A prospective, placebo controlled, triple blind clinical trial was und
ertaken in Thailand to determine the effect of Lactobacillus GG on rec
overy from acute diarrhoea in children. Thirty-nine children (mean age
=8 months) mere enrolled and following rehydration received either ora
l Lactobacillus GG (n=20) as a freeze-dried preparation or placebo (n=
19) twice daily far 2 days. The clinical characteristics of the study
groups were similar. There was no significant difference overall in cl
inical response detected between the study groups. When only those wit
h 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 frequenc
y 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.
