摘要: 目的 研究慢性乙型肝炎患者HBV基因型和亚型流行情况。方法 应用HBV基因型和亚型特异性引物PCR法对北京、长春、大连、西安、石家庄、郑州和合肥7个城市660份HBV DNA阳性慢性乙型肝炎患者血清进行基因型和亚型分析。结果 在660份HBV DNA阳性血清中,B基因型、C基因型和B/C混合感染分别为16.67%(110/660)、74.54%(492/660)和 8.79%(58/660);在C基因型中,C1亚型6例(1.22%)、C2亚型473例(96.14%)、C1/C2混合基因亚型13例(2.64%);B基因型均为Ba亚型,B基因型和C基因型混合感染者均为Ba与C2亚型混合感染,未发现其他基因型和基因亚型;不同基因型感染患者HBeAg阳性率差异无统计学意义(P=0.153);B基因型和C基因型患者之间血清HBV DNA水平差异无统计学意义(6.37±1.62 lg copies/ml对6.29±1.76 lg copies/ml),但均高于B和C基因型混合感染患者(5.25±1.65 lg copies/ml)。结论 这7个城市慢性乙型肝炎患者以B基因型和C基因型感染为主,有部分B/C基因型混合感染。HBV亚型以Ba和C2亚型占优势。

Abstract: Objective To study hepatitis B virus (HBV) genotypes and subtypes distribution in chronic hepatitis B patients. Methods Genotype/subtype-specific primer PCR was used to detect HBV genotypes and subtypes in 660 chronic hepatitis B patients from Beijing(n=474),Shijiazhuang(n=40),Changchun(n=55),Dalian(n=20),Zhengzhou(n=33), Xi’an(n=26) and Hefei(n=12). Results Among 660 patients with chronic hepatitis B (all with serum HBV DNA positive),the prevalences of genotype B,C,and B/C subtype were 16.67%(110/660),74.54%(492/660),and 8.79%(58/660),respectively;In genotype C-infected patients,6(1.22%) were subtype C1,473(96.14%) were subtype C2,and 13(2.64%) were C1/C2 coinfection;All genotype B were subtype Ba;There was no significant difference of HBeAg positivities or serum HBV DNA levels between subtype B and subtype C infected patients. Conclusion The common HBV genotypes in these seven cities are genotype B and C,and genotype C prevail,while subtypes Ba and C2 are predominant.
