Low prevalence of Clostridioides difficile infection in acute severe ulcerative colitis: A retrospective cohort study from northern India

Background The incidence of Clostridioides difficile infection (CDI) is high in ulcerative colitis and is associated with disease flares and adverse outcomes. However, the data on the dynamics of CDI in patients with acute severe ulcerative colitis (ASUC) is rather scarce. We evaluated the prevalenc...

Description
Summary:Background The incidence of Clostridioides difficile infection (CDI) is high in ulcerative colitis and is associated with disease flares and adverse outcomes. However, the data on the dynamics of CDI in patients with acute severe ulcerative colitis (ASUC) is rather scarce. We evaluated the prevalence of CDI in patients with ASUC. Methods This retrospective analysis of a prospectively maintained cohort admitted to the All India Institute of Medical Sciences, India, from May 2016 to December 2021, included patients with ASUC (as per Truelove and Witts criteria) who were tested for CDI. CDI testing was performed using enzyme-linked immunoassay for toxins A and B. Risk factors for developing CDI were analyzed along with short-term outcomes of ASUC. Steroid failure was defined as the need for medical rescue therapy or colectomy. Results Total 153 patients with ASUC were included (mean age 34.92 ± 12.24 years; males 56.2%; disease duration 36 (IQR: 16–55.5) months, pancolitis 67.3%). Ninety-eight (63.4%), 72 (47%) and 10 (6.5%) patients, respectively, had received steroids, azathioprine and biologics in the past. Forty patients (26.14%) had a prior history of ASUC. Among risk factors for CDI, 14% of the patients had prior admission within 30 days, 22.2% had a recent history of antibiotics and 3.9% had long-term non-steroidal anti-inflammatory drug intake. Only one sample was positive for Clostridioides difficile toxin assay. Tissue Cytomegalovirus DNA-PCR positivity was noted in 57 patients (37.3%). Fifty-seven patients (37.3%) had steroid failure, 35 required medical rescue therapy and 30 (19.6%) required colectomy (eight after medical rescue therapy failure). Conclusion Despite antecedent risk factors for CDI, the overall prevalence of CDI in ASUC was low and the outcomes were determined by underlying disease severity.
