Given the diarrhea did not improve within the four first days of hospitalization, gelatin tannate was since prescribed. Gelatin tannate has been recently approved in Europe as a medical device to control and reduce the symptoms associated with diarrhea. The use of tannates for the treatment of diarrhea in infants and children has been proven to be effective and safe in previous studies, leading to significant decrease of both the duration of diarrhea and number of watery stools within the first 24 to 48 hours either against placebo [6] or compared to ORS alone [7]. The mechanism of action for gelatin tannate is not entirely clear but it is thought to act locally on the intestinal wall via the formation of a protein-based film thereby protecting the gut from the irritable effect of intestinal secretions responsible for intestinal toxemia. Tannins are well known for their astringent properties, permitting the precipitation of proinflammatory mucoproteins from the intestinal mucus responsible for local inflammation and elimination through the feces
