JCLA:不同基因型丙型肝炎病毒RNA与核心抗原的相关性?

2019-05-16 不详 网络

本研究的目的分析不同基因型丙型肝炎病毒(HCV) RNA与HCV核心抗原(HCV cAg)的相关性。

本研究的目的分析不同基因型丙型肝炎病毒(HCV) RNAHCV核心抗原(HCV cAg)的相关性。

研究纳入106例经丙型肝炎病毒RNA检测确诊为丙型肝炎病毒感染的患者。用PCR荧光探针检测HCV基因型。分别用化学发光微粒子免疫(CMIA)和酶联免疫吸附法(ELISA)检测血清中HCV cAg的表达,并比较阳性率。分析了不同基因型HCV RNAHCV cAg的相关性。

研究显示106例丙型肝炎病毒感染者的HCV基因型分布如下:1b基因型46 (43.4%);2a基因型7 (6.6%);3a基因型18 (17.0%);3b基因型3 (2.8%);6a基因型9 (8.5%);1b/3b混合型13 (12.3%);10(9.4%)丙肝病毒cAg CMIAELISA检测到100%56%,统计学意义(χ2 = 60.38,P = 0.000)1b基因型组HCV cAg高于3b1b/3b基因型组,差异有统计学意义(U = 3.0, P = 0.006, U = 165, P = 0.014)1b基因型HCV RNAHCV cAg呈正相关(r = 0.894, P = 0.04)

丙型肝炎病毒基因型的主要遗传亚型为1b。与ELISA法相比,CMIA法检测丙型肝炎cAg可提高阳性率,促进丙型肝炎患者的早期诊断和治疗。随着丙型肝炎病毒RNA载量的增加和丙型肝炎病毒cAg的表达,丙型肝炎病毒cAg可作为诊断1b基因型丙型肝炎病毒感染的早期指标。
