Infliximab-Associated Immunomediated Hepatitis in Children With Inflammatory Bowel Disease

Abstract

Infliximab (IFX) is commonly used to induce and maintain remission in inflammatory bowel disease (IBD). We report the first 2 cases of children with ulcerative colitis who had normal liver transaminases before IFX and were diagnosed with immunomediated hepatitis after IFX induction. Both the cases had negative antibodies for antinuclear, smooth muscle, and liver kidney microsome, with 1 patient having positive autoimmune serology (dsDNA) and overlap primary sclerosing cholangitis. IFX was discontinued and transaminases normalized without steroid administration. Clinicians treating pediatric patients with IBD with IFX should be aware of IFX immunomediated hepatitis. This phenomenon is previously reported in adult patients with IBD. To our knowledge, these are the first cases reported in pediatric patients with IBD.
