摘要
目的探讨乙型肝炎病毒(HBV)复制情况及其基因分型与HBV相关慢性肝病病变程度之间的关系。方法对500例HBV相关慢性肝病患者进行乙肝标记物、HBV-DNA定量检测,采用PCR微板核酸杂交-ELISA法检测HBV基因型,观察HBV-DNA基因型分布,同时观察慢性乙型肝炎、肝炎后肝硬化、肝细胞癌中基因型的分布差异。结果基因型以B型和C型为主,分别为47.1%和52.9%。慢性肝炎中以B型为主,肝硬化中以C型占优,而在肝细胞癌中B型和C型所占百分比差异无统计学意义。结论 C型HBV感染与乙肝病情加重、肝硬化发生有一定关系;而B型HBV感染者在慢性肝炎中多见,提示预后相对较好。
Objective To examine the correlation between hepatitis B virus（HBV） replication/HBV genotype and HBV- related chronic liver disease. Methods HBV markers and the quantity of HBV-DNA were detected in 500 patients with chronic HBV infections. The HBV genotypes of all the patients were determined by PCR microplate hybridization-ELISA method. The difference in the HBV genotype among chronic HBV disease,liver cirrhosis and hepatocellular carcinoma was evaluated. Results HBV genotypes B and C were commonly seen in patients suffering HBV-related chronic liver disease,and the positive rate of these two genotypes reached 47.1 % and 52.9 % respectively. Genotype B was the most dominant type in chronic hepatitis and genotype C in liver cirrhosis. The percentage of genotype B was not significantly different from that of genotype C in hepatoeel- lular carcinoma. Conclusion Genotype C is associated with the exacerbation of hepatitis and liver cirrhosis. Genotype B infection is more common in chronic hepatitis and it suggests a relatively good prognosis.
