Antibiotic-associated Diarrhea | Lactobacillus Reuteri in the Prevention of Antibiotic Associated-diarrhea and Clostridium Difficile

Antibiotic-associated Diarrhea research study

What is the primary objective of this study?

The purpose of this study is to find whether Lactobacillus reuteri prevents antibiotic-associated diarrhea and related Clostridium difficile infections. Subjects will be admitted from the University Hospitals Case Medical Center. They will be randomly assigned to an intervention group receiving L. reuteri or a placebo. Supplementation will occur during antibiotic treatment and for an additional 7 days after cessation of treatment. Data collection will occur at baseline, end of antibiotic use, 7 days after antibiotic cessation, and 21 days after antibiotic cessation. Primary data includes diarrhea instances. Secondary data includes severity of diarrhea, presence of C. difficile toxins, and presence of other GI symptoms.
