Abstract

Background: The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has emerged as a dramatic challenge for all healthcare systems worldwide. This outbreak immediately affected gastroenterologists as well as global physicians worldwide because COVID-19 can be associated with not only triggering respiratory inflammation but also gastrointestinal (GI) inflammation based on the mechanism by which SARS-CoV-2 enters cells via its receptor the angiotensin-converting enzyme 2, which is expressed on GI cells. However, the comorbidity spectrum of digestive system in patients with COVID-19 remains unknown. Because the inflammatory bowel disease (IBD) management involves treating uncontrolled inflammation with immune-based therapies, physicians, and patients have great concern about whether IBD patients are more susceptible to SARS-CoV-2 infection and have worsened disease courses.

Summary: It is necessary to precisely ascertain the risk of SARS-CoV-2 infection and the COVID-19 severity in IBD patients and to acknowledge the IBD management during the COVID-19 pandemic with clinically reliable information from COVID-19 cohorts and IBD experts' opinions. In this review, we highlight clinical questions regarding IBD management during the COVID-19 pandemic and make comments corresponding to each question based on recent publications. Key Messages: We propose that there is (1) no evidence that IBD itself increases the risk of SARS-CoV-2 infection, (2) to basically prioritize the control of disease activity of IBD, (3) no need for physicians to suddenly discontinue immunomodulatory or biologic therapy in patients with quiescent IBD, and (4) a need for careful observation of elderly (>60 years old) and IBD patients receiving corticosteroid treatment during the COVID-19 pandemic.
