乙型肝炎表面抗原阳性肝硬化患者前S1抗原、e抗原及乙型肝炎病毒DNA结果分析DOI: CNKI:51-1356/R.20120115.1546.014, PP. 63-65 Keywords: 肝硬化,乙型肝炎病毒前S1抗原,乙型肝炎病毒e抗原,乙型肝炎病毒核酸定量检测 Abstract: 目的 探讨乙型肝炎病毒(HBV)表面抗原(HBsAg)阳性肝硬化患者血清中HBV前S1抗原(前S1抗原)、HBVe抗原(HBeAg)及HBV核酸定量检测(HBVDNA)相关性。方法 2008年7月-2011年5月对97例HBsAg阳性肝硬化住院患者和50份HBsAg阴性的健康体检者血清进行前S1抗原、HBV血清标志物检测及实时荧光定量PCR检测HBVDNA结果进行分析。结果 97份HBsAg阳性肝硬化患者血清中,前S1抗原、HBeAg及HBVDNA阳性率分别为53.6%(52/97)、22.7%(22/97)及61.8%(60/97)。22例HBeAg阳性血清中,前S1抗原阳性18例(81.8%),HBVDNA阳性20例(90.9%)。75例HBeAg阴性血清中,前S1抗原阳性34例(45.3%),HBVDNA阳性40例(53.3%),两者的前S1抗原与HBVDNA结果间都具有很好的相关性。HBVDNA含量与前S1抗原及HBeAg阳性结果显示HBsAg阳性的肝硬化患者血清中HBVDNA阴性率为38.1%(含量<103copies/mL),而阳性检出率HBVDNA含量主要集中在103~105copies/mL,占81.7%(49/60),HBVDNA含量>105copies/mL占18.3%(11/60)。结论 HBsAg阳性的肝硬化患者血清中主要以HBV非HBeAg阳性血清学模式为主,HBVDNA阳性检出率的含量主要集中在103~105copies/mL。前S1抗原在HBeAg阳性血清中与其含有HBsAg病毒及HBeAg阳性患者具有很好的相关性,而在HBeAg阴性血清中存在着差异。Objective TostudythecorrelationamongPre-S1antigen,HBeAgandHBVDNAresultsinpatientswithHBsAg-positivelivercirrhosis.Methods Weretrospectivelyanalyzedtheserumpre-S1-antigen,HBVserummarkersandreal-timequantitativePCRHBVDNAresultsin97patientswithHBsAg-positivelivercirrhosisand50HBsAg-negativehealthyvolunteersinourhospitalfromJuly2008toMay2011.Results Amongthe97samplesofHBsAg-positivelivercirrhosispatients’serum,thepositiveratesofPre-S1antigen,HBeAgandHBVDNAwere53.6%(52/97),22.7%(22/97)and61.8%(60/97),respectively.Inthe22samplesofHBeAg-positiveserum,thenumberofpositivepre-S1antigenandHBVDNAwas18(81.8%)and20,respectively.Inthe75samplesofnegativeHBeAgserum,thenumberofpositivepre-S1antigenandHBVDNAwas34(45.3%)and40(53.3%)respectively.Thepre-S1antigenwascorrelatedwellwithHBVDNAresultsinboththetwogroups.HBVDNAlevel,pre-S1antigenandHBeAg-positiveresultsshowedthattheserumHBVDNAnegativerateofHBsAg-positivepatientswithcirrhosiswas38.1%(<103copies/mL),whilethepositiverateofHBVDNAlevelwasmainlyconcentratedat103~105copies/mL,accountingfor81.7%(49/60),andHBVDNAlevelover105copies/mLaccountedforonly18.3%(11/60).Conclusions HBsAg-positivepatientswithcirrhosismainlyhaveaserumnon-HBeAg-positiveHBVserologypattern,andHBVDNApositiverateofthecontentismainlyconcentratedat103~105copies/mL.Thereisagoodcorrelationbetweenpre-S1antigeninHBeAg-positiveserumandpatientswithHBsAgvirusorpositiveHBeAg,whileforPre-S1antigeninHBeAg-negativeserum,itisquitedifferent.
