随着近30%的世界人口被感染,B型肝炎病毒(HBV)在世界范围内引起显著的发病率和死亡率。尽管目前使用了几种有效的抗病毒药物来对抗HBV感染,但大多数慢性感染个体不能实现功能性和完全治愈,如通过从血液中清除HB表面抗原(HBsAg)和从肝细胞核中清除共价闭合环状DNA(cccDNA)所测量的。此外,即使接受治疗的患者达到长期(> 10-15年)持续的病毒学应答(检测不到HBV DNA),仍有很高的风险发生肝脏并发症的发病率和死亡率。本文综述了目前正在开发或临床评价中的新型、机制多样的抗HBV治疗策略,并强调了新的联合策略,这些策略可能有助于从感染的肝脏中完全消除HBV DNA和cccDNA,从而完全治愈慢性B型肝炎。
With nearly 30% of the world population infected, hepatitis B virus (HBV) causes significant morbidity and mortality worldwide. Although several potent antiviral agents are currently in use against HBV infection, the majority of chronically infected individuals do not achieve a functional and complete cure, as measured by the clearance of HB surface antigen (HBsAg) from blood and eradication of the covalently closed-circular DNA (cccDNA) from the nuclei of hepatocytes. In addition, even treated persons who achieve a long-term (> 10-15 years) sustained virological response (undetectable HBV DNA), are still at high risk of developing morbidity and mortality from liver complications. This review focuses upon novel, mechanistically diverse anti-HBV therapeutic strategies that are currently in development or in clinical evaluation, and highlights new combination strategies which may contribute to full elimination of HBV DNA and cccDNA from the infected liver, leading to a complete cure of chronic hepatitis B.
