Clinical cure strategies for chronic hepatitis B patients with hepatitis B virus surface antigen <100 IU/mL after treatment with nucleos(t)ide analogues
-
摘要: 在长期接受核苷(酸)类似物(NAs)治疗的慢性乙型肝炎(CHB)患者中,10%~20%可达到乙型肝炎病毒表面抗原(HBsAg)<100 IU/mL的低水平状态。该人群是实现临床治愈(HBsAg清除)的优势人群,也是当前停药及联合治疗策略重点关注的对象。在临床管理策略选择方面,基于“免疫再激活”理论的NAs停药策略虽能促使部分患者(尤其是高加索人群)实现HBsAg清除,但其停药后复发风险不容忽视。以聚乙二醇干扰素α为基础的治疗策略显示出更高的主动清除潜力,部分新型免疫调节剂亦显示出初步疗效。总体而言,对于HBsAg<100 IU/mL的NAs经治CHB患者,应基于个体风险与获益,审慎评估停药或主动联合治疗路径。未来需结合更精细的生物标志物进行精准分层,并探索有限疗程、安全高效的新型联合方案,以推动更多患者实现临床治愈,并降低远期肝病风险。

Abstract: Among chronic hepatitis B patients undergoing long-term treatment with nucleos(t)ide analogues (NAs), approximately 10%—20% can achieve a low level of <100 IU/mL for hepatitis B surface antigen (HBsAg). These patients have the advantage to achieve clinical cure (HBsAg clearance) and are currently a key focus for treatment discontinuation and combination treatment strategies. As for the selection of clinical management strategies, the NAs discontinuation strategy, based on the “immune reactivation” hypothesis, may lead to HBsAg clearance in some patients, especially among Caucasians, but the risk of recurrence after discontinuation cannot be neglected. The treatment strategies based on pegylated interferon-α exhibit a higher potential for active HBsAg clearance, and some novel immunomodulators have also shown preliminary efficacy. Overall, for patients with HBsAg <100 IU/mL previously treated with NAs, treatment discontinuation or active combination treatment should be carefully assessed based on individual risk-benefit profiles. In the future, it is essential to incorporate more refined biomarkers for precise stratification and explore novel combination regimens with finite treatment courses that are safe and highly effective, in order to help more patients achieve clinical cure and reduce long-term risks of liver disease. -
