Update in clinical science: Autoimmune hepatitis

Abstract

Autoimmune hepatitis (AIH) is an enigmatic, relatively rare disease with a variable spectrum of presentation whose pathogenesis, diagnosis and management remain a major challenge. We have performed a review of recent developments in basic science, epidemiology, clinical science, therapeutics, and regulatory science, evaluating the challenges associated with the application of translational research and clinical trial design to a condition that is a chameleon in nature, where outcomes range from relatively benign disease through cirrhosis and acute liver failure. This review is focused on developments from 2020 onwards so we can present a forward-looking view on the challenges and remaining questions that must be addressed to improve patient care and outcomes in AIH. We also outline areas of debate and offer insights into these areas.
