  【摘 要】 目的  探讨定量检测乙型肝炎病毒血清标志物(HBVM)与(HBV DNA)定量之间的关系及临床意义。 方法  采用实时荧光定量PCR仪检测HBV DNA,采用时间分辨荧光免疫分析仪检测HBVM。 结果  375例乙肝患者在HBV DNA含量分组中,随HBV DNA含量增高,HBsAg、HBeAg含量也增高,后两者与前者有良好的一致性,存在一定的相关性(r=0.5332,r=0.3809)。抗HBs,抗HBe及抗HBc与HBV DNA之间,无明显规律。HBsAg含量:慢性轻度肝炎分别与急性肝炎、慢性重度、亚重肝、慢性重型肝炎,肝硬化比较差异有非常显著性(P<0.01,0.05或0.001),HBeAg含量:慢性轻度肝炎分别与急性肝炎、慢性中度、慢性重度、亚重肝、慢性重肝,肝硬化比较差异非常显著(P<0.01或0.001),HBsAg含量及HBeAg含量在其他临床分型中比较部分有统计学意义。HBV DNA阳性率及HBV DNA定量在部分临床分型中比较有统计学意义。 结论  时间分辨荧光免疫(DELFIA)是一敏感、特异方法,定量检测HBsAg、HBeAg能反映HBV DNA载量及复制情况;部分情况表明肝脏病变越重,其HBsAg及HBeAg血清含量越低,HBV DNA阳性率及HBV DNA载量与乙肝临床分型之间关系无确定性结论。

    The relationship between hepatitic B virus markers through quantity testing and HBV DNA quantity and their clinical signifi┐cance GAO Yu-jin,LIU Cheng-yong,SUN Qing.(Hospital of infectious Diseases and Hepatitis Research Institute,Xuzhou Jiangsu221004,China)

    【Abstract】 Objective To explore the clinical significance and the relationship between the HBV DNA quantity and the quanti-ty testing of HBVM.Methods HBV DNA was tested with the real-time fluorescent quantitative PCR,and Hepatitis B virus markers with time-resolution immunofluorescence.Results In the375cases of Hepatitis B,the increase of the quantity of HBV DNA was followed by that of HBsAg and HBeAg,with the latter two fairly coherent and closely relevant to the former(r=0.5332,r=0.3809).Anti-HBs,anti-HBe or anti-HBc is not related to HBV DNA regularly.Quantity of HBsAg:A remarkable dif-ference between chronic low-degree hepatitis B and acute hepatitis B,chronic severe degree hepatitis B,sub-severe hepatiti B,chronic severe hepatitis B,or hepatocirrhosis.Quantity of HBeAg:A remarkable difference between chronic low-degree hepatitis B and acute hepatitis B,chronic mild degree hepatitis B,chronic severe degree hepatitis B,sub-severe hepatitis B,chronic severe hepatitis B,or hepatocirrhosis(P<0.01,0.05or0.001).The quantity of HBsAg and that of HBeAg for other clinical classifica-tions illustrate statistical significance,and so is the case with parts of clinical classifications in positive proportion and quantity of HBV DNA.Conclusion Quantity testing of HBsAg/HBeAg with sensitive,special DELFIA can reflect the quantity of HBVD-NA and its copies.Part of exploration shows that the severer a hepatic disease is,the lower the quantity of blood serum in HBsAg and HBeAg will be;No final conclusion can be drawn upon between the positive proportion of HBVDNA,the quantity of HBVD-NA and clinical classifications of hepatitis B.

    乙型肝炎病毒标志物(HBVM)以往采用ELISA法定性检测,近年来采用时间分辨荧光免疫分析等方法定量检测已渐用于临床,其具有敏感性高、特异性强,无放射污染等特点;HBVDNA定量检测能更好了解患者病毒载量变化,同时对评估抗病毒疗效及患者预后有重要的参考价值,本文就定量检原则,以期收到较为理想的治疗效果。
