1概述  自身免疫性肝炎(AIH)是一种由针对肝细胞的自身免疫反应所介导的肝脏实质炎症,以血清自身抗体阳性、高免疫球蛋白G(IgG)和(或)γ-球蛋白血症、肝组织学上存在界面性肝炎为特点,如不治疗常可导致肝硬化、肝衰竭[1]。AIH的临床表现多样,一般表现为慢性、隐匿起病,但也可表现为急性发作,甚至引起急性肝衰竭。20世纪60至80年代,多项临床研究证实,免疫抑制剂治疗可显著改善AIH患者的生物化学指标及临床症状,甚至能逆转肝纤维化,从而显著改善患者预后和生存质量。随着自身抗体和肝活组织病理学检查的广泛开展,我国AIH患者检出率逐年增加。AIH已成为非病毒性肝病的重要组成部分,越来越受到我国消化和肝病学界专家和临床医师的关注[2]。
