乙型肝炎病毒DNA与血清标志物的关系

目的探讨乙型肝炎(下称乙肝)免疫标志物(HBV-M)两对半模式与乙肝病毒核酸(HBV DNA)阳性率及复制水平之间的关系和临床意义。方法乙肝患者血清分别采用酶联免疫吸附试验(ELISA)检测乙肝两对半免疫指标(HBsAg、抗-HBs、HBeAg、抗-HBe、抗-HBc),实时荧光定量-聚合酶链反应(FQ-PCR)检测HBV DNA含量,并对结果进行对比分析。结果在HBV-M不同模式中,HBV DNA的阳性率不同,HBV DNA含量也不相同;在HBV-M中HBeAg阳性与HBV DNA检出率呈正相关。以HBsAg(+)HBeAg(+)抗-HBc(+)组(大三阳组)HBV DNA的阳性率最高,病毒载量较高。结论不同HBV-M具有不同的临床意义,而HBV DNA是衡量乙肝传染性的最精确指标,是确定HBV感染不同复制状态的检测手段,HBV DNA阳性表明有完整的病毒颗粒复制,即有传染性。因此,联合检测HBV-M和HBV DNA,不仅可以提高检出率,避免漏诊,而且为临床对HBV感染、复制、传染性判定以及抗病毒治疗的疗效评估提供了更为可靠的判定依据。

Relation between virus serum markers and nucleic acid of hepatitis B virus

Objective To discuss the connection between immunity markers of hepatitis B virus serum markers(HBV-M) and the positive rate and duplication of HBV DNA and its clinical meaning.Methods To detect the immunity markers of HBV-M(HBsAg,HBsAb,HBeAg,HBeAb,HBcAb) with ELISA and DNA content of HBV with FQ-PCR in order to do contrast analysis.Results If the HBV-M was different,the positive rate of HBV DNA was also different,the content of HBV DNA was also different;the positive rate of HBeAg had positive correlation ...
