Rituximab-induced autoimmune hepatitis: A case study and literature review.

Rituximab is a monoclonal antibody to CD20, often used to treat B-cell lymphomas and various autoimmune diseases. While there is extensive literature on rituximab-induced liver injury related to hepatitis B reactivation, there have been no reports to date of autoimmune-type idiopathic drug-induced liver injury from this drug. We present a case of necro-inflammatory hepatitis with autoimmune features in a 40-year-old female after receiving a second dose of rituximab for mucosa-associated lymphoid tissue (MALT) lymphoma, with a review of the literature.
