Abstract

Abstract: Background: The impact of COVID-19 has been of great concern in patients with inflammatory bowel disease (IBD) worldwide, including an increased risk of severe outcomes and/or possible flare of IBD. This study aims to evaluate prevalence, outcomes, the impact of COVID-19 in patients with IBD, and risk factors associated with severe COVID-19 or flare of IBD activity. Methods: A consecutive cohort of IBD patients followed at the McGill University Health Care Centre diagnosed with COVID-19 infection was obtained between March 1, 2020, and April 30, 2021. Demographics, comorbidities, IBD (type, treatments, pre-and post-COVID clinical activity, biomarkers, and endoscopic activity), and COVID-related outcomes (pneumonia, hospitalization, death, and flare of IBD disease) were analyzed. Results: A total of 3, 516 IBD cohort patients were included. 82 patients (2.3%) were diagnosed with COVID-19 infection (median age 39.0 (IQR 27.8–48.0), 77% with Crohn's disease, 50% were female). The prevalence of COVID infection in IBD was significantly lower compared to the general population in Canada and Quebec (3.5% vs. 4.3%, p<0.001). Severe COVID occurred in 6 patients (7.3%); 2 patients (2.4%) died. A flare of IBD post-COVID infection was reported in 8 patients (9.8%) within 3 months. Biologic therapy was held during active COVID infection in 37% of patients. Age ≥55 years (odds ratio (OR):11.1, 95%CI:1.8–68.0), systemic corticosteroid use (OR:4.6, 95%CI:0.7–30.1), active IBD (OR:3.8, 95%CI:0.7–20.8) and comorbidity (OR:4.9, 95%CI:0.8–28.6) were factors associated with severe COVID. After initial infection, 61% of IBD patients received COVID-19 vaccinations. Conclusion: The prevalence of COVID-19 infection among patients with IBD was lower than that in the general population in Canada. Severe COVID, mortality, and flare of IBD were relatively rare, while a large proportion of patients received COVID vaccination. Older age, comorbidities, active IBD disease, and systemic corticosteroid, but not immunosuppressive or biological therapy were associated with severe COVID infection.
