IBDtreatment and body mass index correlated with COVID-19 disease development with symptoms.CONCLUSIONThe IBD population does not have a higher risk of severe COVID-19. The relative risk of havingSARS-CoV-2 antibodies and symptoms was higher for patients taking azathioprine, then biologictherapy and lastly mesalazine. None of the patients under biologic therapy developed severeCOVID-19.展开更多
