摘要: 核苷(酸)类似物(NAs)和干扰素(IFN)α治疗慢性乙型肝炎(CHB)患者能有效抑制病毒复制、阻止疾病进展和降低肝细胞癌的发生。但由于肝内共价闭合环状DNA难以被清除,治愈CHB仍面临巨大挑战。开发新型抗乙型肝炎病毒治疗药物有望使CHB功能治愈的目标在未来成为现实。在现有治疗策略中,长期NAs经治的CHB患者序贯或序贯联合IFNα治疗能提高应答率,使部分患者实现功能性治愈。

Abstract: Treatment of chronic hepatitis B (CHB) with nucleos(t)ide  analogs (NA) and interferonα (IFNα) can lead to a significant suppression of viral replication, as well as reduced risk of disease progression and hepatocellular carcinoma. However, challenge remains regarding curing CHB because hepatic covalently closed circular DNA can not be completely eradicated. Discovering new drugs targeted hepatitis B virus may enable the possibility of functional curing CHB in future. Among available therapeutic strategies, switching to or sequential combination with IFNα in patients with longterm NA treatment can induce increased percentages of responses, even make the likelihood of functional cure in a proportion of patients.
