Clostridium difficile infection (CDI) is the most common infectious cause of nosocomial diarrhea, comprising 10-20% of all cases. CDI is a significant complication for IBD patients. Not only can CDI induce IBD flare, IBD patients also experience significantly higher CDI recurrence when compared to the general population. New monoclonal antibody (mAB) therapies, such as bezlotoxumab, have improved management of recurrent CDI (rCDI). The MODIFY I/II trial included 44 patients with known IBD, 28 of which received bezlotoxumab.
