[Clinical characteristics, diagnosis, and treatment strategies for drug-induced autoimmune hepatitis]

Drug-induced liver injury (DILI) is an important adverse drug reaction with diverse clinical manifestations. Drug-induced autoimmune-like hepatitis (DI-ALH) is a special type of DILI possessing clinical, serological, and histological features similar to autoimmune hepatitis (AIH). However, there are significant differences between DI-ALH and AIH in terms of treatment plan, course of disease, and prognosis; therefore, differential diagnosis between DI-ALH and AIH is crucial. This article summarizes the epidemiology, pathogenesis, clinical characteristics, diagnosis and differential diagnosis, treatment, and prognosis of DI-ALH and analyzes the existing problems in order to provide guidance for the diagnosis, treatment, and future research direction.
