杭州地区体检人群乙型肝炎病毒标志物阴性结果分析

Analysis of negative results of hepatitis B virus markers in healthy population in Hangzhou district

目的分析2014年杭州地区体检人群乙型肝炎病毒血清学五项标志物(HBV-M)全阴模式的分布特征,为预防和控制HBV-M阴性人群感染乙型肝炎病毒(HBV)提供对策。方法采用ELISA对体检人群的血液标本进行HBV-M(HBsAg、HBsAb、HBeAg、HBeAb和HBcAb)检测。对保存的300例HBV-M阴性标本,分别使用化学发光免疫分析法检测HBsAg、HBsAb和PROCLEIX ULTRIOAssay检测HBV-DNA,对HBV-DNA反应性标本进行病毒载量测定。结果在检测的9 143例体检者的标本中,2 213例标本为HBV-M阴性,阴性率为24.20%;男女HBV-M阴性率比值为1∶1.21。使用化学发光免疫分析法和PROCLEIX ULTRIOAssay分别检测出1例低浓度的HBsAg标本(HBsAb及HBV DNA均无反应性),4例低浓度的HBsAb标本(HBsAg及HBV DNA均无反应性),2例HBV-DNA反应性标本(HBV-M阴性)。其中1例HBV-DNA反应性标本定量检测为560IU/mL。结论杭州地区ELISA HBV-M阴性的体检人群中,少数人可检出低浓度的HBsAg或HBsAb或HBV DNA。针对ELISA HBV-M阴性人群,建议接种乙肝疫苗前进行HBV-M和HBV-DNA定量检测,以确定是否需要接种乙肝疫苗及接种乙肝疫苗的方案。

Objective To analyse the distribution characteristics of negative pattern of hepatitis B virus Markers （HBV‐M ） in healthy population in Hangzhou district in 2014 ,and provide strategy for the prevention and control of HBV infection in HBV‐M negative population .Methods The HBV‐M （HBsAg ,HBsAb ,HBeAg ,HBeAb and HBcAb） in blood specimens of health examina‐tion population were tested by using ELISA .For 300 cases preserved HBV‐M negative specimens ,HBsAg and HBsAb were detec‐ted by using chemiluminescence immunoassay and HBV‐DNA was detected by using PROCLEIX ULTRIO？ Assay .The viral load of HBV‐DNA reactive sample was quantitatively determined .Results Among 9 143 blood samples ,2 213 samples were HBV‐M negative ,and the negative rate was 24 .20% .The negative rate of male to female was 1∶1 .21 .Using chemiluminescence immunoas‐says and PROCLEIX ULTRIO？ Assay simultaneously ,we found one case of low concentration of HBsAg（both HBsAb and HBV DNA nonreactive） ,four cases of low concentration of HBsAb（both HBsAg and HBV DNA nonreactive） ,two cases of HBV‐DNA reactive（HBV‐M negative） .One HBV‐DNA reactive sample could be quantified as 560 IU/mL .Conclusion In HBV‐M （ELISA） negative population of health examination of Hangzhou district ,a few subjects had low concentrations of HBsAg or HBsAb or HBV‐DNA .For HBV‐M negative population ,quantitative detection of HBV‐M and HBV‐DNA before HBV vaccination is recom‐mended to determine w hether they need HBV vaccine and the HBV vaccination plan .
