抗病毒治疗期间慢性乙型肝炎病毒 (HBV) 感染患者的 HBsAg 或 HBeAg 血清转化预测指标仍然难以捉摸。我们的目的是研究基线时 HBsAb 特异性 B 细胞的存在是否可以预测 HBsAg 或 HBeAg 血清转化。在这项研究中,纳入了 134 名未经治疗的慢性乙型肝炎患者。对所有入组患者进行基线 HBsAb 特异性 B 细胞 ELISpot 测定。对于接受 Peg-IFN-α 治疗的患者,在第 12、24 和 48 周收集血清样本;对于接受 NA 治疗的患者,在 1 年、3 年和 5 年收集血清样本。进行了 HBsAg、HBsAb、HBeAg、HBeAb、HBcAb、HBV DNA、ALT 和 AST 的实验室检测。我们观察到,慢性 HBV 患者中 HBsAb 特异性 B 细胞的频率明显低于健康个体。在 Peg-IFN-α 治疗组中,41.2% 具有基线 HBsAb 特异性 B 细胞的患者实现 HBsAg 血清转换,而基线不具有 HBsAb 特异性 B 细胞的患者中只有 13.6% 实现 HBsAg 血清转换 (p = 0.006)。通过逻辑回归分析,基线 HBsAb 特异性 B 细胞和 HBsAg ≤ 1500 的患者在治疗结束时具有较高的 HBsAg 清除率 (p < 0.05)。在 NA 治疗组中,基线 HBsAb 特异性 B 细胞的患者中有 58.3% 实现了 HBeAg 血清转化,而基线不具有 HBsAb 特异性 B 细胞的患者中只有 30.0% 实现了 HBeAg 血清转化 (p = 0.114)。我们的结果表明,通过 ELISpot 检测得出的基线 HBsAb 特异性 B 细胞可能是慢性 HBV 治疗患者中 HBsAg 或 HBeAg 血清转化的有价值的预测生物标志物。
Indices for predicting HBsAg or HBeAg seroconversion in patients with chronic hepatitis B virus (HBV) infection during antiviral therapy remain elusive. We aimed to investigate if the presence of HBsAb-specific B cells at baseline can predict HBsAg or HBeAg seroconversion. In this study, 134 treatment-naive patients with chronic HBV were enrolled. A baseline HBsAb-specific B cell ELISpot assay was performed for all the patients that enrolled. Serum samples were collected at 12, 24, and 48 weeks for patients treated with Peg-IFN-α, or at 1 year, 3 years, and 5 years for patients treated with NAs. Laboratory testing of HBsAg, HBsAb, HBeAg, HBeAb, HBcAb, HBV DNA, ALT, and AST was done. We observed a significantly lower frequency of HBsAb-specific B cells in patients with chronic HBV than in healthy individuals . In the Peg-IFN-α-treated group, 41.2% of patients with baseline HBsAb-specific B cells achieved HBsAg seroconversion, while only 13.6% of patients without baseline HBsAb-specific B cells achieved HBsAg seroconversion (p = 0.006). By logistic regression analysis, patients with baseline HBsAb-specific B cells and HBsAg ≤ 1500 had higher HBsAg clearance at the end of treatment (p < 0.05). In the NA-treated group, 58.3% of patients with baseline HBsAb-specific B cells achieved HBeAg seroconversion, whereas only 30.0% of patients without baseline HBsAb-specific B cells achieved HBeAg seroconversion (p = 0.114). Our result revealed that baseline HBsAb-specific B cells by ELISpot assay might be a valuable predictive biomarker of HBsAg or HBeAg seroconversion in patients with chronic HBV on treatment.
