Management of inflammatory bowel disease during the COVID-19 pandemic

The COVID-19 pandemic, caused by novel coronavirus SARS-CoV-2, has had an enormous impact on public health, medical systems, economies, and social conditions. The pandemic has also greatly influenced medical care systems for patients with inflammatory bowel disease (IBD). Establishment of a global registry system and accumulated experiences have led to consensus for IBD management under the COVID-19 pandemic. IBD itself does not pose an increased risk of SARS-CoV-2 infection or aggravation of COVID-19, and immune-control treatments other than systemic steroids, such as biologics, are unlikely to increase this risk. The importance of suppressing disease activity has not changed since before the pandemic. The effects of the COVID-19 pandemic on behavioral changes and psychological states among patients have various results and differ by country or region as well as between adult and pediatric patients. In future, information-sharing tools that can widely and correctly disseminate the views of experts will be very important. Vaccination remains in its infancy, but the impact of immunoregulatory therapy on antibody titers must be investigated. Information about COVID-19 is constantly being updated, and new and accurate medical care updates are needed. In Japan, the Japan COVID-19 Taskforce contributes to information dissemination, patient registries, and clinical research.
