Sci Rep:血清HBcrAg是乙肝HBV-DNA的一种新型标志物!

2017-03-13 MedSci MedSci原创

最近,有一些建议认为乙型肝炎核心相关抗原(HBcrAg)可以作为乙型肝炎病毒(HBV)感染的另一种标记物。近期,一项发表在杂志Sci Rep上的研究旨在探讨血清定量HBcrAg(qHBcrAg)是否为肝内共价闭合环状DNA(cccDNA)的一种替代标志物。此项研究共有139名患者进行肝活检,包括59名免疫耐受(IT)阶段患者,52名免疫清除(IC)阶段患者,18名低复制(LR)阶段患者以及10名重

最近,有一些建议认为乙型肝炎核心相关抗原(HBcrAg)可以作为乙型肝炎病毒(HBV)感染的另一种标记物。


近期,一项发表在杂志Sci Rep上的研究旨在探讨血清定量HBcrAg(qHBcrAg)是否为肝内共价闭合环状DNA(cccDNA)的一种替代标志物。

此项研究共有139名患者进行肝活检,包括59名免疫耐受(IT)阶段患者,52名免疫清除(IC)阶段患者,18名低复制(LR)阶段患者以及10名重新激活阶段患者。所有IC期的患者均接受恩替卡韦(ETV)治疗,其中有32例患者在24个月时接受第二次肝活检。

在这些患者中,qHBcrAg与肝内cccDNA强相关,优于qHBsAg和HBV DNA。在IT,IC,LR和再激活阶段的患者中也观察到类似的发现。

在IC期第二次肝活检的32例ETV治疗的患者中,肝内cccDNA的下降伴随着qHBcrAg和qHBsAg的变化。然而,与qHBsAg相比,qHBcrAg的变化更强烈地与肝内cccDNA下降相关。

此研究表明,血清qHBcrAg可以作为CHB患者肝内HBV cccDNA令人满意的一种替代物。

乙肝疫苗后不产生抗体!这是为什么?

肝疫苗按规定时间接种了3次,但几个月后复查乙肝病毒五项指标,疫苗没有产生效果——乙肝表面抗体始终不产生。大概有以下几种情况:1、检测方法不精确:实际已产生抗体,但因检测方法不精确而致结果阴性。这时应当用最灵敏的方法,如酶联免疫法或放射免疫法来重新检测。因为有的地方检测方法不先进或不灵敏而得出假阴性结果。2、免疫反应太弱:机体对疫苗的免疫反应太弱,只产生微量的抗体,以至用先进的检测方法仍未能发现表面
