摘要

摘要: 目的了解HBV基因型（HBV/B和HBV/C）对血清HBsAg水平的影响。方法对492例慢乙型肝炎患者应用亚培12000进行血清HBsAg定量检测,基因分型采用PCR联合限制性片段长度多态性方法。将不同基因型HBV复制质粒转染Huh7细胞,比较HBsAg分泌效率。结果HBV/B患者（n=260）血清HBsAg水平高于HBV/C（n=197）患者（P<0.001）。以全部患者为研究对象的多变量回归分析发现,HBV DNA水平（B=0.098,P=0.002）、HBeAg状态（B=0.594,P<0.001）和HBV基因型（B=-0.420,P<0.001）决定血清HBsAg水平;在HBeAg（+）患者中（n=337）,HBV DNA水平（B=0.136,P=0.001）、性别（B=0.441,P=0.011）和HBV基因型（B=-0.278,P=0.049）决定血清HBsAg水平;而在HBeAg（-）患者中（n=155）,仅HBV DNA水平（B=0.195,P=0.018）是影响血清HBsAg水平的因素。转染试验表明HBV/C的HBsAg的分泌效率仅有HBV/B的1/...

Abstract: Objective To investigate the impacts of HBV genotypes (HBV/B and HBV/C) on serum HBsAg levels in chronic hepatitis B patients.Methods Quantification of serum HBsAg was performed with Abbott 12000 and HBV genotypes were determined by PCR-RFLP in 492 patients.Replicative plasmids contained common genotype HBV genome was transiently transfected into Huh7 cells and HBsAg secretion profile was compared.Results Serum HBsAg levels in patients infected with HBV/B (n=260) were higher (P<0.001) than those in HBV/C (n=197) .Multivariate regression analysis with all 492 subjects showed that HBV DNA levels (B=0.098.P=0.002) .HBeAg status (B=0.594.P<0.001) and HBV genotype (B=-0.420.P<0.001) had significant influences on serum HBsAg levels.Regression analysis in HBeAg (+) patients (n=337) showed that HBV DNA (B=0.136, P=0.001) .gender (B=0.441.P=0.011) and HBV genotype (B=-0.278, P=0.049) determined serum HBsAg levels.however.in HBeAg (-) patients (n=155) HNV DNA (B=0.195.P=0.018) was the only factor influenced serum HBsAg levels.HBsAg sectetion efficiency was 33% in HBV/C transfection to that in HBV/B (P=0.010) .Conclusion HBV genotypes affected serum HBsAg levels through different HBsAg secretion efficiency in HBeAg chronic hepatitis B patients.
