Core Tip

Core Tip: The management of hepatitis B virus (HBV) infection poses significant challenges for patients with inflammatory bowel disease (IBD). Lower rates of vaccination for HBV have been reported in this population and immunization programs should be encouraged and intensively implemented. In addition, patients who receive immune-modifying therapies may develop suboptimal responses to vaccination. In the presence of present or past HBV infection, immunosuppressive therapies may increase the risk for reactivation of the virus with adverse clinical outcomes. Close surveillance and/or prophylactic anti-viral treatment may be employed depending on the status of HBV infection and the IBD-specific therapy.
