Background
Clostridium difficile infection (CDI) is one of the leading causes of health-care-associated infections in the USA. There are limited data available regarding CDI in hospitalized patients with inflammatory bowel disease-related ileal pouch.
Aims
This study aimed to evaluate the demographics, clinical features, risk factors, and admission outcomes among hospitalized patients with CDI-related pouchitis (CDP).
Methods
Retrospective chart review was performed for patients who were admitted to our institute for pouchitis between 2013 and 2016 to identify patients with CDP. Logistic regression analysis was performed to assess the risk factors associated with CDP.
Results
A total of 160 subjects with pouchitis had a total of 218 admissions during the study period. Primary admission diagnosis was pouchitis or inflammatory bowel disease flare-up for 202 (93%) admissions. Clostridium difficile was tested at least once for 72 patients, and the diagnosis of CDP was established for 16 (10%) patients. All patients with CDP were symptomatic, 13 (81%) had diarrhea, 8 (50%) had abdominal pain, 7 (44%) had nausea/vomiting, and 2 (13%) had gastrointestinal bleeding. On multivariable analysis, only body mass index > 25 (OR 0.25, 95% CI 0.06–0.94, p = 0.048) was significantly associated with decreased risk of CDP. No patients in CDP cohort were admitted to ICU, died at the hospital, or readmitted in 30 days after the discharge.
Conclusions
In our cohort, obesity was associated with low risk of CDP among hospitalized patients with pouchitis. This finding warrants further validation in prospective studies.
