Abstract
Autoimmune hepatitis (AIH) is a kind of immune-mediated chronic liver disease, and its specific pathogenesis has not yet been fully elucidated. In recent years, the International Autoimmune Hepatitis Expert Group has revised histology and autoantibody evaluation criteria for diagnosing AIH and has clarified the definition of treatment response. The current standard treatment regimen is still glucocorticoids and azathioprine, but novel biological agents offer new therapeutic options for patients with refractory AIH. This article reviews the new progress in the diagnosis and treatment of AIH and explores the current challenges and future research directions.
