Autoimmune Hepatitis During Ledipasvir/Sofosbuvir Treatment of Hepatitis C: A Case Report.

We report the case of a woman with chronic hepatitis C and idiopathic thrombocytopenic purpura (ITP) who developed autoimmune hepatitis (AIH) during antiviral therapy with ledipasvir (LDV)/sofosbuvir (SOF). The onset of acute hepatitis rose two weeks after starting treatment with LDV/SOF when HCV-RNA tested negative, suggesting a link between rapid HCV clearance and autoimmune diseases. This case report proposes new immunologic scenarios in patients with hepatitis C virus (HCV) with laboratory or clinical signs of autoimmunity during direct-acting antiviral (DAA) therapy.
