摘要


目的:探讨口服恩替卡韦治疗HBeAg阳性乙肝患者48周对血清HBV-DNA和肝组织中HBV cccDNA含量的影响。方法:选取30例HBeAg阳性乙肝患者,所有患者连续48周口服恩替卡韦0.5mg/d,治疗前后分别静脉取血分离血清。检测HBV血清标志物、HBV-DNA及HBVcccDNA含量,并对各指标进行统计学分析。选取治疗48周后血清HBV-DNA未转阴患者,行肝穿检测HBV cccDNA含量。结果:(1)治疗后,血清HBV-DNA、谷丙转氨酶(ALT)水平均显著下降。(2)接受恩替卡韦治疗48周后,血清中HBV-DNA检测结果为阴性(<1.0×10IU/mL)的患者为25例(阴转率为83.3%),对HBV-DNA未转阴的5例患者行肝穿,检测肝细胞中HBV cccDNA含量,仅有1例患者未检测到HBV cccDNA,4例患者可检测到的HBV cccDNA(区间:103-102IU/mL)。(3)接受恩替卡韦治疗48周后,HBeAg阴转率33.3%(10例患者发生e抗原转阴),HBeAg/抗HBe转换率23.3%(7例患者发生血清学转换)。结论:尽管恩替卡韦可明显降低乙肝患者血清HBV-DNA,但恩替卡韦不能彻底清除肝细胞中的HBV。
