Used alongside rehydration therapy, probiotics appear to be safe and have clear beneficial effects in shortening the duration and reducing stool frequency in acute infectious diarrhoea. However, more research is needed to guide the use of particular probiotic regimens in specific patient groups.
Efficacy of high-dose Lactobacillus rhamnosus GG in controlling acute watery diarrhea in Indian children: a randomized controlled trial.
To evaluate the effective dose of Lactobacillus rhamnosus GG (LGG) as probiotic in acute watery diarrhea (AWD) in Indian children.
                Hospital-based study.
                Randomized, controlled, blinded trial.
                All patients of AWD admitted over 1 year were included in the study. They were randomized into 3 groups to receive either only oral rehydration solution (ORS) (group A/control), ORS+LGG powder containing 10(10) colony forming units (CFU) (group B), or ORS+LGG powder containing 10(12) CFU (group C) twice daily for a minimum period of 7 days or until diarrhea stopped along with correction of dehydration. None of them received any other drug such as antibiotic or antidiarrheal medication. The duration and frequency of diarrhea and vomiting were studied. Data were analyzed by SPSS-10 software.
                The study comprised of 559 patients, group A/controls (n=185), group B (n=188), and group C (n=186). All the groups were similar with respect to age, number of breastfed infants, presentation with dehydration, degree of protein energy malnutrition, and rotavirus infection. The frequency and duration of diarrhea, requirement for intravenous therapy, and hospital stay were significantly lower in both the intervention groups compared with the controls. There was no significant difference between the 2 intervention groups. No complication was observed from the doses of LGG used.
                Both the doses of LGG (10(10) and 10(12) CFU) were equally effective to decrease the frequency and duration of diarrhea and reduction in hospital stay in patients of AWD.
