The role of low levels of HDV-RNA during and after interferon therapy of hepatitis D is unknown. We re-analysed HDV RNA in 372 samples collected in the HIDIT-2 trial (Wedemeyer et al, Lancet Infectious Diseases 2019) with the Robogene assay (RA; Jena Analytics). Data were compared with the previously reported in-house assay (IA). We detected HDV-RNA in one-third of samples previously classified as undetectable using the highly sensitive RA. Low HDV viraemia detectable at week 48 or week 96 was associated with a high risk for post-treatment relapse, defined as HDV RNA positivity in both assays at week 120. HDV RNA relapses occurred in 10/15 (67%) patients with detectable low HDV RNA at week 48 and in 10/13 (77%) patients with low viraemia samples at week 96. In contrast, the post-treatment relapse rate was lower in patients with undetectable HDV RNA in both assays during treatment.
丁型肝炎干扰素治疗期间及之后低水平丁型肝炎病毒核糖核酸(HDV-RNA)的作用尚不清楚。我们使用Robogene检测法(RA;耶拿分析公司)对在HIDIT-2试验(韦德迈尔等人,《柳叶刀·传染病学》2019年)中收集的372份样本中的HDV RNA进行了重新分析。将数据与先前报告的内部检测法(IA)进行了比较。我们在先前使用高度灵敏的RA检测法分类为检测不到的三分之一样本中检测到了HDV-RNA。在第48周或第96周可检测到的低HDV病毒血症与治疗后复发的高风险相关,治疗后复发定义为在第120周两种检测法中HDV RNA均呈阳性。在第48周HDV RNA可检测到的低水平患者中,10/15(67%)出现了HDV RNA复发,在第96周病毒血症水平低的样本患者中,10/13(77%)出现了复发。相比之下,在治疗期间两种检测法中HDV RNA均检测不到的患者,其治疗后复发率较低。
