乙型肝炎病毒X区T^1762－A^1764和前C区A^1896变异对干扰素治疗的影响
被引量：1
摘要
目的：研究乙型肝炎病毒(HBV)基因组X区和前C区热点变异对干扰素(IFN)治疗的影响。方法：采用半套式聚合酶链反应(HN-PCR．)结合限制性片段长度多形态(RFLP)技术检测20例慢性乙型肝炎患者IFN治疗前病毒核苷酸序列的突变。结果：A^1896变异株不影响治疗结束时应答率，6／8例T^1762-A^1764变异株感染者为应答者。停药后12mo时，l例T^1762-A^1764变异株感染者由无应答者变为应答者：在复发者中，既有T^1762-A^1764变异株感染者，又有A^1896变异株感染者，或两者同时存在。结论：T^1762-A^1764变异者近期疗效好，而A^1896变异者不影响近期疗效；T^1762-A^1764变异者远期疗效还有待进一步观察。
