    Abstract:
    OBJECTIVE: To investigate the clinical features of Clostridium difficile infection (CDI) in hospitalized patients with inflammatory bowel disease (IBD) and to analyze the impact of CDI on IBD. METHODS: A prospective study on patients newly diagnosed with IBD was conducted at the IBD center at Sir Run Run Shaw Hospital from March 2015 to May 2016. Stool samples for anaerobic culture and polymerase chain reaction were used to test CDI and to detect the different toxins in the groups. The patients were followed up for 2 years. RESULTS: Altogether 230 patients with IBD were enrolled, including 77 with ulcerative colitis (UC) and 153 with Crohn's disease (CD). The incidence rate of CDI was 13.9% (32/230). Patients with UC were more susceptible to CDI than those with CD (24.7% vs 8.5%, P < 0.01). Among UC patients, a long disease course, prior hospitalization, proton pump inhibitor use, and disease severity were associated with an increased risk of CDI (all P < 0.05). CDI prolonged hospital stay and increased the rate of long-term surgery rate in UC (both P < 0.05). Among patients with CD, CDI increased both short- and long-term surgery rates during the 2-year follow-up (P < 0.05) and increased repeated hospitalization in the follow-up study (odds ratio 2.41, P = 0.02). CONCLUSIONS: A high incidence rate of CDI in patients hospitalized with IBD was related with longer hospital stay and higher surgery rates in our center. Patients with UC are more vulnerable to CDI than those with CD.
