摘要
慢性乙型肝炎(CHB)功能性治愈,即表面抗原(HBsAg)阴转伴有或不伴有表面抗体(抗-HBs)的出现,被视为目前CHB治疗的理想终点。研究表明HBsAg阴转可以降低肝硬化、肝细胞癌等HBV并发症的发生风险。但是HBsAg的阴转率较低,这可能与HBV感染造成的机体免疫耐受状态有关。HBsAg的阴转和/或抗-HBs的出现提示机体针对HBV免疫功能的部分恢复。本文将对影响CHB功能性治愈的因素及其机制进行讨论。
Functional cure of chronic hepatitis B(CHB),defined as negative hepatitis B surface antigen(HBsAg)with or without the pres-ence of hepatitis B surface antibody(anti-HBs),is considered the optimal endpoint for CHB treatment at present.Studies have shown that HBsAg clearance can reduce the risk of HBV complications such as liver cirrhosis and hepatocellular carcinoma.However,HBsAg clearance rate remains at a relatively low level,which may be associated with the immune tolerance state caused by HBV infection.HBsAg clearance and/or the presence of anti-HBs indicate the partial recovery of HBV-specific immunity.This article discusses the influencing factors for the functional cure of CHB and the underlying mechanisms.
