摘要: 目的 探讨雌激素受体α基因 PvuⅡ多态性与慢性乙型肝炎患者干扰素治疗发生早期应答的相关性。方法 采用聚合酶链反应-限制性片段长度多态性法检测100例首次接受干扰素治疗的慢性乙型肝炎患者外周血雌激素α受体基因PvuⅡ多态性,并分析了基因型与干扰素早期应答的相关性。结果 在雌激素受体基因PvuⅡ的PP、Pp和pp三个基因型间, PP基因型患者早期病毒学应答率(70.8%)明显高于Pp(40.0%)和pp(37.2%)基因型,差异具有统计学意义(P<0.05),但早期联合应答率和早期HBeAg血清转换率在PP、Pp和pp三种基因型间的差异均无统计学意义(P>0.05)。结论 研究提示PvuⅡ多态性检测可能是预测慢性乙型肝炎患者干扰素-α治疗后早期应答率的重要因素之一。

Abstract: Objective To investigate the relationship between estrogen receptor α gene polymorphisms and therapeutic response to interferon-alpha in patients with chronic hepatitis B. Methods PvuII polymorphisms of estrogen receptor α(ESR1)gene were analyzed in 100 naive patients with chronic hepatitis B receiving interferon-alpha treatment by polymerase chain reaction-restriction fragment length polymorphism technique. Results Among PP,Pp and pp genotype group,the early virological response were markedly higher in PP genotype groups (70.8%) than 40.0% in Pp and 37.2% in pp genotype group(P<0.05),while neither the combined response nor HBeAg disappearance or seroconversion among PP,Pp and pp genotype groups had no significant difference(P>0.05). Conclusion PvuII genotype polymorphism of ESR1 is associated with early virological response to IFN-α in patients with CHB and the detection of PvuII genotype polymorphism might be helpful for predicting early response to IFN-α treatment.
