Probiotics in the Prevention of Antibiotic Induced Diarrhea and Clostridium Difficile Associated Diarrhea.

The objective of this study is to determine the efficacy of probiotics containing 25Bn (billion) CFU (colony-forming unit) of Lactobacillus rhamnosus, Sacchromyces boulardii and Bifidobacterium breve in the prevention of antibiotic induced diarrhea and Clostridium difficile diarrhea. The chosen population consists of 190 hospitalized patients taking antibiotics. Preselected and randomized patients will take probiotics once daily until 1 week after the course of antibiotic is over or a placebo with 0 CFU. The primary outcome is to detect the occurrence of an antibiotic-associated diarrhea. The secondary outcome is to assess the presence of Clostridium difficile toxins in stool culture.
