2022-12-16 15:05:00 分类:顶刊鉴析

经过二十余载岁月的沉淀,HBV RNA的临床应用方向不断的被探索和挖掘,在此我们重点介绍已有研究成果及应用价值的6个方向:DNA阴性及LLV患者疗效监测、 预测肝细胞癌/与肝细胞癌进展相关性、预测停药后复发风险、 预测经干扰素/核苷类治疗后HBeAg的血清学转换、与肝纤维化/肝硬化进展相关性以及预测HBsAg下降/清除/停药后逆转。其中,DNA阴性及LLV患者疗效监测,预测肝细胞癌/与肝细胞癌进展相关性是目前备受关注的研究方向,而预测停药后复发以及指导干扰素用药是研究较早,是有一定数据基础的方向。

01   DNA阴性及LLV患者疗效监测
  01   DNA阴性及LLV患者疗效监测

● 当前研究现状: 

由于HBV DNA低载量人群缺乏有效的疗效评估指标, 目前在HBV RNA各个方向的研究当中,DNA阴性患者使用HBV RNA进行疗效监测的研究备受关注,已经有数据显示HBV RNA在DNA阴转后有疗效提示价值,以下方向值得继续深挖:

a) HBV DNA高敏阴转后各节点随访HBV RNA阳性比率及具体水平

b) HBV DNA低载量患者HBV RNA与疗效相关性、与更换方案有效性等研究

c) HBV DNA低载量患者HBV RNA与其他不良肝病的相关性

d) HBV DNA低载量患者HBV RNA与其他血清学指标(e.g., HBsAg)的关系

● 当前主要结论: 

HBV RNA阴转时间晚于HBV DNA,在DNA阴转后可继续作为疗效提示指标监测病情。

  02   预测肝细胞癌/与肝细胞癌进展相关性

● 当前研究现状: 

目前关于HBV RNA与肝癌相关性的结论较为统一,HBV RNA阳性的患者无论是从远期肝癌的发生还是从术后肝癌的复发来说,都有更高的风险。但是由于肝癌的前瞻性研究耗时较长、随访跟踪脱落率较高,研究开展存在一定难度。

● 当前主要结论: 

相比于HBV DNA,是更加优良的肝癌风险因子,与肝癌的关系更加紧密,能够提示远期的肝癌发生风险。是肝癌术后复发的风险因子,能够评估患者术后的预后和复发风险。

  03   预测停药后复发风险


● 当前研究现状: 

临床医生认可度较高的一个方向,发表数据较多。“HBV RNA阳性不能停药” 已经被运用到临床患者诊疗中。

 当前主要结论: 

HBV RNA含量与停药后的复发风险密切相关,HBV RNA含量高的病人,更容易发生停药后的病毒学与临床复发。不建议HBV RNA水平大于50 copies/mL的患者停药。HBV RNA还可以与其他指标联用实现更佳的预测效果。

  04 是经干扰素/核苷类治疗后HBeAg的良好预测因子


● 当前研究现状: 

已有不少研究指出HBV RNA在指导干扰素用药、预测HBeAg阴转方面有不错的表现。但是由于使用的HBV RNA检测方法灵敏度存在差异,因此预测HBeAg阴转的准确cut-off值仍有待进一步确定。

● 当前主要结论: 

HBV RNA在基线、12周及24周均能有效预测干扰素治疗的HBeAg血清学转换及病毒学复发。NA治疗患者基线HBV RNA水平与HBeAg清除率和DNA阴转率相关;12周及24周水平是预测HBeAg血清学转换的最佳因子。

  05   与肝纤维化/肝硬化进展相关性


● 当前研究现状: 

目前关于HBV RNA与肝纤维化和肝硬化数据不多,而且现有数据都是一次性截面数据,以下方向值得继续深挖:

a) HBV RNA与肝纤维化进展或逆转的随访数据

b) HBV RNA与肝硬化进展的随访数据

● 当前主要结论: 

HBV RNA水平与肝纤维化/肝硬化水平呈正相关。无论是HBeAg阴性或者HBeAg阳性病人,HBV RNA相比于传统血清学指标FIB-4和APRI可能具有更佳的诊断和预测价值。

  06   预测HBsAg下降/清除/停药后逆转


● 当前研究现状: 

由于S抗原阴转难,在抗病毒治疗过程中下降和变化水平也相对稳定。因此,HBV RNA预测HBsAg下降/清除的研究并不多。HBV RNA在治疗早期预测HBsAg状态的研究有待考证。

● 当前主要结论: 

HBV RNA不仅可以在早期抗病毒治疗期间预测HBsAg的应答,还能在患者停药后预测HBsAg逆转风险。24周时,与未获得HBsAg血清学转换的患者相比,获得HBsAg血清学转换患者的HBV RNA水平下降更迅速。
