Abstract

Background Older age and comorbidities are the main risk factors for adverse COVID-19 outcomes in patients with inflammatory bowel disease (IBD). The impact of IBD medications is still under investigation. Aims To assess risk factors for adverse outcomes of COVID-19 in IBD patients and use the identified risk factors to build risk indices. Methods Observational cohort study. Univariable and multivariable logistic regression was used to identify risk factors associated with pneumonia, hospitalisation, need for ventilatory support, and death. Results Of the 937 patients (446 with ulcerative colitis [UC]) evaluated, 128 (13.7%) had asymptomatic SARS-CoV-2 infection, 664 (70.8%) had a favourable course, and 135 (15.5%) had moderate or severe COVID-19. In UC patients, obesity, active disease and comorbidities were significantly associated with adverse outcomes. In patients with Crohn's disease (CD), age, obesity, comorbidities and an additional immune-mediated inflammatory disease were identified as risk factors. These risk factors were incorporated into two indices to identify patients with UC or CD with a higher risk of adverse COVID-19 outcomes. In multivariable analyses, no single IBD medication was associated with poor COVID-19 outcomes, but anti-TNF agents were associated with a lower risk of pneumonia in UC, and lower risks of hospitalisation and severe COVID-19 in CD. Conclusion The course of COVID-19 in patients with IBD is similar to that in the general population. IBD patients with active disease and comorbidities are at greater risk of adverse COVID-19 outcomes. IBD medications do not pose additional risks. The risk indices may help to identify patients who should be prioritised for COVID-19 re-vaccination or for therapies for SARS-CoV-2 infection.
