Abstract
Data regarding extraintestinal Clostridioides difficile infections (ECDIs) remain scarce and anecdotal. We conducted a retrospective cohort study to investigate characteristics and prognostic factors in patients with ECDI. From January 1997 through December 2018, 60 patients were enrolled and divided into three groups as follows: group A (gastrointestinal [GI] disruption caused by malignancy, n = 13); group B (GI disruption from causes other than malignancy, n = 25); group C (no GI disruption, n = 22). GI disruption was defined as compromised integrity of the GI tract caused by abdominal surgery, perforation, malignancy, enterocolitis, or bleeding. The incidence of ECDI was 2.53 per 100,000 admissions. The most common specimens yielded C. difficile were blood (36.7%), peritoneal fluid (20.0%), and abscesses (16.7%). Six patients (10.0%) had confirmed C. difficile enterocolitis, and 36 patients (60.0%) had a polymicrobial infection. C. difficile bacteremia was significantly more common in group A patients than those in groups B or C (53.8% vs. 48.0% vs. 13.6%, p = 0.02), as was the 30-day mortality rate (69.2% vs. 12.0% vs. 18.2%, respectively; p < 0.001). In multivariate analysis, group A (adjusted odds ratio [aOR], 17.32; 95% confidence interval [CI], 2.96–101.21; p = 0.002) and an age of > 65 years (aOR, 7.09; 95% CI, 1.31–38.45; p = 0.02) were independent risk factors for 30-day mortality. ECDI was uncommonly associated with C. difficile enterocolitis. Two factors, GI disruption caused by malignancy, and old age, were associated with significantly poorer short-term outcomes.
