摘要
目的进一步探讨乙型肝炎病毒(HBV)基因型与血清学标志物及与HBV DNA病毒复制载量的关系。方法研究病例为170例,其中急性乙型肝炎14例、慢性乙型肝炎88例、肝硬化24例、重型肝炎18例、肝细胞癌2例和慢性无症状携带者24例。抽取其外周血,用酶免疫法(EIA法)测定其基因型,同时检测HBV血清标志物和HBV DNA病毒复制载量,分析相互之间的关系。结果检出C基因型105例(61.76%),B基因型59例(34.71%),D基因型3例(1.76%),B+C基因型1例(0.59%)和基因型未明2例(1.18%)。B、C基因型在慢性肝炎、肝硬化、重型肝炎和肝细胞癌病人中分布存在差异(分别为22.94%、52.35%),C基因型病人的HBeAg阳性率与B基因型的HBeAg阳性率无明显差异(P〉0.05)。C基因型病人的HBV DNA病毒复制水平高于B基因型病人的HBV DNA病毒复制水平(P〈0.01).结论C基因型的血清HBV DNA病毒复制水平高于B基因型,病毒复制活跃,C基因型与较重的肝脏损害有一定关系。
Objective To investigate the relationship between the Hepatitis B virus (HBV) genotypes, HBV-M and HBV DNA virus load. Methods 170 patients were detected by Enzyme immunoassary analyzer (EIA) technique. According to clinic type, acute hepatitis 18 cases, chronic hepatitis (CHB) 88 cases, liver cirrhosis (LC) 24 cases, fulminant hepatic failure (FHF) 18 cases, 2 cases of hepatoceliniar carcinoma (HCC) and HBV asymptomatic carriers (ASC) 24 cases. Meantime the HBV DNA virus load and HBV-M were tested. Results Within 170 cases, genotype B 59 (34.71%), genotype C 105 (61.76%), genotype D 3 (1.76%), genotype B+C 1 (1.76%)and 2 (1.18%) cases' of genotype remained unknown. The ratio of genotype B, C in CHB, LC, FHF, HCC patients was 22.94% and 52.35%. The distribution of genotype B or C in CHB, LC, FHF and HCC had no statistic significance (P〉0.05). Comparing the virus load of HBV DNA, it was higher in genotype C group than that in genotype B group, having statistic significance (P〈0.01). Condusions The virus load of HBV DNA in genotype C is significantly higher than that in genotype B. Hepatitis C virus copies actively. And genotype C may induce more severe liver inflammation than genotype B.
