To determine whether patients with IBD have an increased risk of developing SARS-CoV-2 compared with patients without IBD, a nationwide, retrospective cohort study was carried out in the U.S. Veterans Affairs Healthcare System from January 2020 to June 30, 2020. Each patient with IBD was matched with 2 patients without IBD on age, sex, race, location, and comorbidities. The outcome of interest was development of SARSCoV-2.
A total of 38,378 patients with IBD and 67,433 patients without IBD, were evaluated; 87 (0.22%) and 132 (0.20%) patients developed incident CoVID-2 infection, respectively.
It was concluded that patients with IBD are not at significantly increased risk of developing SARS CoV-2 infection when compared with patients without IBD.
