摘要慢性HBV感染仍是全球重大公共卫生问题.慢性乙型肝炎(Chronic hepatitis B, CHB)临床治愈(亦称功能性治愈)即完成有限疗程治疗后,血清HBsAg和HBV DNA持续检测不到、HBeAg阴转、伴或不伴HBsAg血清学转换,肝脏炎症缓解和组织病理学改善,终末期肝病发生率显著降低,是目前国内外最新CHB防治指南推荐的理想治疗目标.临床实践证明,以直接抗病毒药物[如核苷(酸)类似物]或免疫调节剂(如聚乙二醇干扰素α)序贯或联合治疗的优化方案针对部分优势人群显示出良好的疗效,开展了系列成功实现HBsAg阴转的多中心随机对照临床研究. 《慢性乙型肝炎临床治愈(功能性治愈)专家共识》阐述了联合治疗方案的最新循证医学依据,并总结了CHB临床治愈路线图,以指导临床医师治疗决策的制定.

abstractsChronic hepatitis B virus (HBV) infection remains a major public health problem in the world.Current guidelines for the prevention and treatment of chronic hepatitis B ( CHB) have suggested clinical cure ( also known as functional cure ) as the ideal therapeutic goal , which is associated with decreased risk of cirrhosis and hepatocellular carcinoma.Clinical cure is defined as sustainably undetectable serum HBsAg,HBeAg and HBV DNA with or without seroconversion to anti-HBs, but with the persistence of residual cccDNA, accompanied by resolution of liver injury after the completion of a finite course of treatment.Accumulating data from a series of randomized controlled trials as well as clinical practice have confirmed certain clinical benefit of optimal sequential ／combination strategies of direct acting antiviral drugs (DAAs), such as nucleos(t)ide analogues (NAs) or immunomodulators , such as pegylated interferon alpha (PegIFNα) for appropriately selected CHB patients.This consensus provides an updated and comprehensive analysis of the data supporting the use of combination therapies and summarizes the roadmap towards clinical cure of CHB to guide decision-making in clinical practice.
