研究目的: |
(1)明确乙肝疫苗联合聚乙二醇干扰素α-2b治疗是否有助于实现HBsAg阴转及促进抗-HBs产生。 (2)通过检测各组患者的HBsAg、HBsAb、HBV DNA、HBV RNA及其他生化指标,分析乙肝疫苗诱导的免疫应答对抗HBV的效果,揭示乙肝疫苗及联合聚乙二醇干扰素α-2b治疗在实现HBsAg阴转及伴随抗-HBs产生中的作用机制。 (3)探讨各组患者中HBsAg清除率与临床特征、治疗过程中的关键指标之间的相关性,利用统计分析建立HBsAg清除和HBV病毒学应答之间的预测模型,为未来向功能性治愈的转变提供理论依据。 (4)长期随访研究,评估疫苗接种对血清HBsAg复阳率,以及患者HCC发生率、长期生存等结局指标的影响,验证其在维持临床治愈中的持久效益。 (5)评估乙肝疫苗联合聚乙二醇干扰素α-2b在初治和经治慢性乙肝患者中的安全性与耐受性,确定不同组间的治疗副作用发生率,为后续治疗方案的优化提供基础数据。 (6)免疫机制研究,全面评估疫苗接种后对T/B细胞亚群、炎症因子等免疫参数的影响,深入揭示其免疫调控机制。 |

Objectives of Study: |
(1) To clarify whether the treatment of hepatitis B vaccine combined with pegylated interferon α-2b is helpful to achieve negative conversion of HBsAg and promote the production of anti-HBs. (2) By detecting HBsAg, HBsAb, HBV DNA, HBV RNA and other biochemical indicators of patients in each group, the effect of the immune response induced by hepatitis B vaccine against HBV was analyzed, and the mechanism of action of hepatitis B vaccine and combined pegylated interferon α-2b treatment in achieving HBsAg negative conversion and the production of accompanying anti-HBs was revealed. (3) To explore the correlation between HBsAg clearance rate and clinical characteristics as well as key indicators during the treatment process in each group of patients, and to establish a predictive model between HBsAg clearance and HBV virological response through statistical analysis, providing a theoretical basis for the future shift towards functional cure. (4) Long-term follow-up studies were conducted to evaluate the impact of vaccination on the re-positive rate of serum HBsAg, the incidence of HCC in patients, long-term survival and other outcome indicators, and to verify its lasting benefits in maintaining clinical cure. (5) To evaluate the safety and tolerability of hepatitis B vaccine combined with peginterferon α-2b in both newly diagnosed and previously treated patients with chronic hepatitis B, determine the incidence of treatment side effects among different groups. (6) Immune mechanism research, comprehensive evaluation of the impact of vaccination on immune parameters such as T/B cell subsets and inflammatory factors, and in-depth revelation of its immune regulatory mechanism. |
