BACKGROUND: The appendix, considered an intestinal microbiota reservoir, may be protective against the risk of fulminant Clostridium difficile infection.
METHODS: Retrospective analysis was performed in patients with C. difficile infection at St. Francis Medical Center from 2007 to 2011. Outcome of infection and history of appendectomy were compared. Statistical analysis was by chi-square and multivariate logistic regression.
RESULTS: In total, 507 patients were hospitalized for C. difficile. Of 388 patients with intact appendix, 20 (5.2%) developed fulminant infection and required colectomy, whereas of 119 patients with previous appendectomy, 13 (10.9%) required colectomy. An increased severity of disease, indicated by increased rate of colectomy, occurred for the group with a history of appendectomy (P = .03). Age and sex were adjusted by multivariant regression (P = .05).
CONCLUSIONS: Appendectomy may be a risk factor for increased severity of C. difficile infection. Although the mechanism is unknown, further studies are warranted.
