摘要 目的以DNA测序法为标准,探讨实时荧光定量聚合酶链反应(PCR)技术检测乙型肝炎(下称乙肝)病毒YMDD基因变异的敏感性和特异性。方法选取68例乙肝患者经拉米夫定治疗前及治疗9个月后其血清采用荧光定量PCR技术联合检测HBV DNA及YMDD变异,并随机选取10例(5例实时荧光定量PCR提示YMDD变异;5例提示未变异)慢性乙肝患者做DNA测序,分析二者的检测结果。结果拉米夫定治疗前HBVDNA的载量,两组相比差异无统计学意义(P>0.05),9个月后YMDD的变异率为14.7%(10/68);YMDD变异型组HBV DNA无l例阴转,YMDD野生型组HBV DNA阴转率为79.3%(46/58),差异有统计学意义(P<0.01);10例测序法所测结果与实时荧光定量PCR完全相符,总符合率为100.0%。结论实时荧光定量PCR技术联合检测HBV DNA及YMDD变异具有很好的临床应用前景。
