Current Status of Nonantibiotic and Adjunct Therapies for Clostridium difficile Infection.

Clostridium difficile infection (CDI) is a leading cause of nosocomial infections and the most important cause of health care-associated diarrhea worldwide. Standard treatment of CDI consists of modifying underlying antibiotic exposure, aggressive supportive measures, and therapy with specific antibiotics, most commonly metronidazole or vancomycin. This general approach to CDI has remained largely unchanged for decades. In an effort to improve outcomes and reduce recurrences of CDI, interest has been renewed in the development of nonantibiotic and adjunct approaches to therapy. In this review, we highlight some of these recent, resurrected, and novel nonantibiotic treatments.
