乙肝病毒基因型对武汉地区慢性乙型肝炎患者干扰素α-2b疗效的影响

目的:探讨武汉地区慢性乙型肝炎(CHB)患者HBV基因型对干扰素α-2b疗效的影响。方法:以患者年龄、性别、基线指标进行匹配,按照基因分型结果分组,比较干扰素治疗48周时的应答情况。结果:在治疗48周结束时,基因B型HBV感染的患者完全应答率和HBeAg阴转率分别为43.8%(28/64)和68.2%(15/22),显著高于C型患者的完全应答率[22.2%(10/45)]和HBeAg阴转率[28.6%(4/14)]。结论:CHB患者HBV的基因型可影响干扰素α-2b的治疗效果,基因B型在治疗48周时应答情况优于基因C型。

The HBV E Genotype Discover in Dai Nationality in Xishuangbanna, Yunnan Province

To investigate the distribution of Hepatitis B virus (HBV) genotypes among the population of Dai nationality in Xishuangbanna, Yunnan Province HBV genotypes of the Serum samples were tested by PCR-RFLP. This is the first time to discover the B+E genotypes in China. This finding provides new information for understanding the distribution of HBV genotype in China and a provides a basis for establishing a Chinese gene bank.
