本研究目的是利用血清定量的pg-RNA、HBcrAg和HBsAg来识别抗病毒治疗的CHB患者HBsAg血清转化率的预测因子。

本研究目的是利用血清定量的pg-RNA、HBcrAg和HBsAg来识别抗病毒治疗的CHB患者HBsAg血清转化率的预测因子。

研究过程中,在2013年至2017年之间,共招募了335例抗病毒治疗患者,只有23例实现了HBsAg的血清学转化,在312例患者中随机选择了138例未进行HBsAg血清学转化的患者。 在不同时间分析了161例患者的采样日期。 我们将pg-RNA,HBcrAg和HBsAg从基线到6个月和从基线到12个月的滴度降低定义为Δpg-RNA,ΔHBcrAg和ΔHBsAg,然后使用Δpg-RNA,ΔHBcrAg和ΔHBsAg预测HBsAg血清转化。

在接受中位数3.61年的治疗后,约6.9%的患者实现了HBsAg血清转化。 使用ROC预测HBsAg的血清转化,在6周时的ΔHBsAg为0.64 log10 IU / mL,AUC为0.886(0.802,0.969; 95%CI),并且ΔHBsAg为1.45 log10 IU / mL,AUC为0.939(0.868,1.000; 95% CI)在12个月时具有最大化的Youden指数。 使用Kaplan-Meier方法比较23例HBsAg转化患者和138例HBsAg无转化患者的HBcrAg“转化”率,表明两组在抗病毒停药时有显著差异(p = 0.0124)。

研究表明,可以使用ΔHBsAg来选择有可能通过坚持抗病毒治疗实现血清转化的合适患者,这对于达到功能治愈甚至临床治愈的目标非常重要。
