Clostridium difficile infection and inflammatory bowel disease

The importance of Clostridium difficile (C. difficile) infection amongst patients with inflammatory bowel disease (IBD) is increasingly being recognized. Recent studies have demonstrated a concerning trend towards increased rates of infection, morbidity, mortality and health costs, and guidelines now promote testing for C. difficile in IBD patients experiencing a relapse. This critical review focuses on the epidemiology, risk factors, pathogenesis, treatment options and outcomes associated with C. difficile infection in patients with IBD.
