[Viral Hepatitis in Patients with Inflammatory Bowel Disease]

Abstract

There has been a rise in the incidence of inflammatory bowel disease (IBD) in developing countries, including South Korea. Consequently, the use of immunosuppressive agents such as immunomodulators or biologics has also increased. Due to immunosuppression, patients on these agents are at increased risk of various opportunistic infections during treatment, which may sometimes lead to serious adverse outcomes. Viral hepatitis, especially hepatitis B, is one of the infectious conditions that can be reactivated during immunosuppressive therapy, and adequate strategies for monitoring and prophylaxis are needed to prevent it. South Korea is one of the countries with intermediate endemicity for hepatitis A and B. Thus, taking adequate precautions against viral hepatitis could prevent new infections or reactivation of these conditions in patients with IBD on immunosuppressive therapy. In this review article, we have summarized the latest evidence on viral hepatitis in patients with IBD that would be of assistance in clinical practice.
