Abstract

Hepatitis B virus (HBV) RNA in serum is a novel biomarker that reflectscccDNA activity. We investigated whether HBV RNA can predict serological response to peginterferon (PEG-IFN) treatment.Serum HBV RNA levels were retrospectively measured at weeks 0, 12, 24, and 52 of therapy and after treatment discontinuation (week 78) in 266 HBeAg-positive chronic HBV patients who had participated in a global randomized controlled trial (HBV99-01 study). Patients received 52 weeks PEG-IFN monotherapy (n=136) orPEG-IFN and lamivudine (n=130). The primary endpoint was HBeAg loss 24 weeks after PEG-IFN discontinuation. At baseline, the mean serum level of HBV RNA was 6.8 (SD 1.2) log c/mL. HBV RNA levels declined to 4.7 (1.7) log c/mL after one year of PEG-IFN therapy alone and to 3.3 (1.2)log c/mL after combination therapy. From week 12 onward, HBV RNA level was significantly lower in patients who achieved HBeAg loss at the end of follow-up as compared to those who did not, regardless of treatment allocation (week 12: 4.4 vs. 5.1 log c/mL, p=0.01; week 24: 3.7 vs. 4.9 log c/mL, p<0.001). The performance of a multivariable model based on HBV RNA level was comparable at week 12 (AUC 0.68)and 24 (AUC 0.72) of therapy. HBV RNA level above 5.5 log c/mL at week 12 showed negative predictive values of 93/67/90/64% for HBV genotypes A/B/C/D for the prediction of HBeAg loss. In conclusion, HBV RNA in serum declines profoundly during PEG-IFN treatment. Early on-treatment HBV RNA level may be used to predict non-response.

抽象

血清中的乙型肝炎病毒（HBV）RNA是反映cccDNA活性的新型生物标记。我们调查了HBV RNA是否可以预测对聚乙二醇干扰素（PEG-IFN）治疗的血清学反应。在266例HBeAg阳性患者中，在治疗的第0、12、24和52周以及停药后（第78周）回顾性测量了血清HBV RNA水平。参加了一项全球随机对照试验（HBV99-01研究）的慢性HBV患者。患者接受52周的PEG-IFN单药治疗（n = 136）或PEG-IFN和拉米夫定（n = 130）。主要终点是停用PEG-IFN 24周后HBeAg丢失。在基线时，HBV RNA的平均血清水平为6.8（SD 1.2）log c / mL。单独使用PEG-IFN治疗一年后，HBV RNA水平下降至4.7（1.7）log c / mL，联合治疗后下降至3.3（1.2）log c / mL。从第12周开始，无论治疗分配如何，随访结束时实现HBeAg丢失的患者的HBV RNA水平均显着低于未接受治疗的患者（第12周：4.4 vs. 5.1 log c / mL，p = 0.01；第24周：3.7 vs. 4.9 log c / mL，p <0.001）。在治疗的第12周（AUC 0.68）和24周（AUC 0.72），基于HBV RNA水平的多变量模型的性能相当。在第12周时，高于5.5 log c / mL的HBV RNA水平显示A / B / C / D HBV基因型对HBeAg丢失的预测为93/67/90/64％的阴性预测值。总之，在PEG-IFN治疗期间，血清中的HBV RNA急剧下降。早期治疗中的HBV RNA水平可用于预测无反应。
