Probiotic for the Prevention of Functional Disorders in Childhood

The present study has several aims: 1. Establish whether Lactobacillus Rhamnosus Strain GG is able to prevent the onset of IBS in a high risk group of children enrolled after an acute gastroenteritis (the study has been powered to this aim). 2. Establish whether Lactobacillus Rhamnosus Strain GG is able to stabilize the intestinal microbiota after an acute gastroenteritis. 3. Define the intestinal microbiota of children following an acute gastroenteritis and identify, if possible, a modification of the microbiota that can predict the emergence of Irritable Bowel Syndrome.
