摘  要:目的评价恩替卡韦(ETV)长期治疗拉米夫定(LAM)失效的慢性乙型肝炎(CHB)患者的疗效和安全性。方法2003年参加ETV(1.0mg/d)治疗LAM失效CHB患者II期临床实验(ETV-056)的32例患者,继续接受ETV的延长治疗至第8年,检测不同时期患者病毒学、血清学及生物化学的应答情况。结果分析采用按意向性治疗原则(ITT)方法。结果HBVDNA〈300拷贝/ml的患者百分比在基线及8、12、24、48、96、144、192、240、420周分别为0、6.3%(2/32)、9.4%(3/32)、18.8%(6/32)、18.8%(6/32)、46.9%(15/32)、43.8%(14/32)、50.O%(16/32)、50.0%(16/32)、62.5%(20/32)。病毒学反弹率在48、96、168、192、240、420周分别为6.1%(2/32)、9.40/0(3/32)、12.5%(4/32)、18.8%(6/32)、25.0%(8/32)、28.1%(9/32)。8年的HBeAg血清学转换率为32.3%(10/31),HBsAg血清学转换共4例。结论ETV(1.0mg/d)长期治疗LAM失效的CHB患者,在抑制病毒及增加血清学转换方面疗效有限,长程应用安全肚良好,但经济成本高,病毒学反弹率随时间明显增加。Objective To evaluate the efficacy and safety of entecavir (ETV) as a long-term treatment in patients with lamivudine (LAM)-refractory chronic hepatitis B (CHB). Methods In this phase II study of ETV-056, 32 CHB patients with resistance to LAM monotherapy were administered ETV at 1.0 mg/day and monitored over a period of 8 years. The virologic, serologic and biochemical responses were measured throughout the treatment course. Outcomes analysis was conducted according to intention- to-treat principles. Results At baseline and treatment weeks 8, 12, 24, 48, 96, 144, 192, 240, and 420, the proportion of patients with hepatitis B virus (HBV) DNA 〈 300 copies/ml was 0, 6.3% (2/32), 9.4% (3/32), 18.8% (6/32), 18.8%(6/32), 46.9% (15/32), 43.8% (14/32), 50.0% (16/32), 50.0% (16/32), and 62.5% (20/32). At treatment weeks 48, 96, 168, 192, 240, and 420, the proportion of patients experiencing virological breakthrough was 6.1% (2/32), 9.4% (3/32), 12.5% (4/32), 18.8%(6/32), 25.0%(8/32), and 28.1% (9/32). In the 8 year study period, 32.3% (10/31) of patients achieved HBs seroconversion and four patients achieved HBe seroconversion. Conclusion While treatment with 1.0 mg/day ETV for up to 8 years resulted in mild HBV DNA suppression and increase of HBeAg seroconversion, the safety profile of this therapy was good but the economic cost was high and virological breakthrough rates were high.
