INTRODUCTION Hepatitis B virus (HBV) infection is associated with the onset of several major liver diseases. Inactive hepatitis B surface antigen (HBsAg) carriers (IHCs) may be successfully treated with PEGylated interferon-α2b (PEG-IFNα2b)-based antiviral therapy; however, studies on this treatment have been insufficient. In this study, we evaluated the efficacy and safety of PEG-IFNα2b treatment in IHCs. METHODS Nineteen IHCs were treated with subcutaneous PEG-IFNα2b (180 μg/week) for 48 weeks (treatment group). Patients were followed up for 24 weeks after treatment discontinuation. Twenty untreated control patients were observed for 72 weeks (control group). HBsAg clearance (HBsAg < 0.05 IU/mL), HBsAg seroconversion, and alanine aminotransferase levels were monitored. RESULTS Of the 19 patients treated with PEG-IFNα2b, 16 showed HBsAg loss (84.2%), and 13 showed HBsAg seroconversion (68.4%) at 72 weeks. All patients in the treatment group exhibited virological response (serum HBV DNA level < 10 IU/mL) at the time of drug withdrawal. In the control group, no patients experienced HBsAg loss during the observational period. There were no serious adverse events during treatment, and the therapy was well tolerated. CONCLUSIONS Short PEG-IFNα2b therapy in IHCs produced a high functional cure rate and good safety profile, suggesting that PEG-IFNα2b treatment may be the best choice for clinical cure of some IHCs.

聚乙二醇化干扰素-α2b 治疗非活性乙型肝炎表面抗原载体的疗效和安全性分析。

引言 乙型肝炎病毒 (HBV) 感染与几种主要肝脏疾病的发生有关。非活动性乙型肝炎表面抗原 (HBsAg) 携带者 (IHCs) 可通过基于聚乙二醇化干扰素-α2b (PEG-IFNα2b) 的抗病毒疗法成功治疗;然而,对这种治疗的研究还不够充分。在本研究中,我们评估了 PEG-IFNα2b 治疗 IHC 的有效性和安全性。方法 19 个 IHC 用皮下 PEG-IFNα2b(180 μg/周)治疗 48 周(治疗组)。患者在停止治疗后随访 24 周。20 名未经治疗的对照患者被观察了 72 周(对照组)。监测 HBsAg 清除率(HBsAg < 0.05 IU/mL)、HBsAg 血清转化和丙氨酸转氨酶水平。结果 在接受 PEG-IFNα2b 治疗的 19 名患者中,16 例显示 HBsAg 消失(84.2%),13 例显示 HBsAg 血清学转换(68.4%)在 72 周时。治疗组所有患者在停药时均表现出病毒学反应(血清HBV DNA水平<10 IU/mL)。在对照组中,在观察期内没有患者出现 HBsAg 消失。治疗期间未发生严重不良事件,治疗耐受性良好。结论 PEG-IFNα2b 治疗 IHCs 具有较高的功能治愈率和良好的安全性,表明 PEG-IFNα2b 治疗可能是某些 IHCs 临床治愈的最佳选择。在观察期内没有患者出现 HBsAg 消失。治疗期间未发生严重不良事件,治疗耐受性良好。结论 PEG-IFNα2b 治疗 IHCs 具有较高的功能治愈率和良好的安全性,表明 PEG-IFNα2b 治疗可能是某些 IHCs 临床治愈的最佳选择。在观察期内没有患者出现 HBsAg 消失。治疗期间未发生严重不良事件,治疗耐受性良好。结论 PEG-IFNα2b 治疗 IHCs 具有较高的功能治愈率和良好的安全性,表明 PEG-IFNα2b 治疗可能是某些 IHCs 临床治愈的最佳选择。
