摘要 目的观察替比夫定(LDT)治疗HBeAg阳性慢性乙型肝炎(CHB)患者48周疗效、HBeAg变化及可能的影响因素。方法检测46例HBeAg阳性CHB患者在LDT治疗前及治疗12周、24周、48周时ALT、HBVDNA定量、HBeAg定量、HBeAg阴转及血清转换率、HBsAg定量,以治疗48周时HBeAg阴转与否分A、B两组,观察两组在治疗前及治疗12周、24周、48周各项指标比较差异有无统计学意义。结果随治疗时间延长,HBVDNA定量、HBeAg定量、HBsAg定量呈逐步下降趋势,治疗48周时ALT复常率91.60%,HBVDNA阴转率89.13%,HBeAg阴转率34.78%,HBeAg血清学转换率26.09%,1例患者出现HBsAg阴转,HBsAg阴转率2.2%;治疗48周HBeAg阴转组患者在治疗前ALT水平较高,治疗12周HBVDNA阴转率100%,治疗12周、24周HBeAg定量较治疗前的下降更为明显,治疗24周、48周时HBsAg定量较治疗前的下降更为明显,与未阴转组比较差异有统计学意义。结论 LDT治疗HBeAg阳性CHB患者具有较强抑制病毒能力、较高HBeAg血清转换率,且伴有HBsAg定量的下降;治疗前ALT水平较高、12周HBVDNA阴转、治疗12周及24周HBeAg明显下降、治疗24周及48周HBsAg明显下降对治疗48周HBeAg阴转具有预测作用。
