慢性乙型病毒性肝炎分为慢性迁延性肝炎(简称慢迁肝)和慢性活动性肝炎(简称慢活肝),前者为非进行性的,预后良好,后者为进行性者,预后较差,二者在临床、生化、病理、治疗和转归方面均有不同,其发病机理目前虽未完全清楚,但国内外学者公认细胞免疫和特异性抗体缺陷或不足,是导致乙型肝炎病毒慢性感染的主要原因,慢迁肝一般无自身免疫表现,而慢活肝的病机与自身免疫有密切关系,自身免疫的形成认为是抑制性T细胞功能不全所致,因此,目前国内外对慢性乙肝的治 Chronic hepatitis B virus is divided into chronic persistent hepatitis (referred to as slowly moving liver) and chronic active hepatitis (referred to as slow living liver), the former is non-progressive, the prognosis is good, the latter is progressive, the prognosis is poor , Both in clinical, biochemical, pathological, treatment and prognosis are different, the pathogenesis is not yet fully understood, but scholars at home and abroad recognize cellular immunity and specific antibody defects or deficiencies, is leading to chronic hepatitis B The main reason for infection, slowly moving liver generally no autoimmune manifestations, and chronic liver disease pathogenesis and autoimmunity are closely related to the formation of autoimmune is considered to be caused by inhibition of T cell dysfunction, therefore, at home and abroad on chronic Hepatitis B treatment
