Autoimmune hepatitis after vaccination against COVID-19

Abstract

Summary: In this case report, we present a 61-year-old patient admitted to the hospital because of tiredness and jaundice less than three weeks after vaccination against SARS-CoV-2 with the first dose of the Comirnaty vaccine (Pfizer/BioNTech). Based on the patient’s medical history, laboratory data, imaging methods and liver bio­psy, we dia­gnosed autoimmune hepatitis. The patient developed acute liver failure, and his liver function did not improve after corticosteroid administration. Therefore, the patient was enrolled in the waiting list and underwent a successful orthotopic liver transplantation. Key words: autoimmune hepatitis – COVID-19 – vaccination – liver failure
