[Immunotherapy with Immune Checkpoint Inhibitors and Hepatitis].

Immunotherapy, with « checkpoint » inhibitors (CPIs), has become an essential therapeutic weapon against cancer. Autoimmune disorders related to overactivation of the immune system are well known side effects. The risk of reactivation of the hepatitis B and C viruses and exacerbation of the hepatitis, known from the introduction of immunosuppressive drugs such as chemotherapy, is poorly documented under immunotherapy.
