Abstract:
      目的了解母婴匹配人群隐匿性HBV感染(OBI)及显性和隐匿性病毒株s基因的变异。方法基础调查时随访135对母婴,填写调查表及采血样,采用ELISA检测HBsAg,Real—time PcR测定病毒载量,PCR扩增HBV S基因并进行进化分析。结果共采集母血94份,其子女血样101份,OBI感染率分别为10.0%和2.0%,母亲显著高于其子女;显性和隐匿性病毒株病毒载量中位数分别为399.9 IU/ml和247.6 IU/ml,两者差异无统计学意义;OBI病毒株有l株为B基因型、adw血清型,其余7株均为C基因型、adr血清型;显性HBV感染病毒株有15株为B基因型、adw血清型,其余8株为c基因型、adr血清型;OBI病毒株中C基因型比例显著高于显性HBV病毒株。结论母婴人群存在一定比例的OBI,应重视其预防。
English Abstract:
      Objective Prevalence of occult hepatitis B virus (HBV) infection (OBI) was investigated in a paired mother-teenager population and HBV S gene variation including overt and occult HBV,was determined.Methods A follow-up study based on an initial survey of 135 mother-teenager pairs was carried out through collection of questionnaires and blood samples HBsAg were detected by ELISA method,viral load by PCR amplification and HBV S gene by phylogenetic analysis.Results 102 pairs of subjects were followed-up.Blood samples from 94 mothers and 101children were collected.OBI prevalence in mothers was 10.0% (6/60),significantly higher than 2.0%(2/101) in teenagers.Medians of viral load were 399.9 IU/ml and 247.6 IU/ml in overt and occult HBV strains,but without significant difference.1 occult HBV strain belonged to genotype B with serotype adw while the other 7 were genotype C with serotype adr.15 of the overt HBV strains belonged to genotype B with serotype adw and the other 8 were genotype C with serotype adr.Proportions of genotype-C strains were significantly higher in occult HBV strains than in overt HBV strains.Conclusion OBI was seen in teenage-mother population.
