摘要
目的分析恩替卡韦与α干扰素在不同基线丙氨酸氨基转移酶(ALT)水平治疗48周后的疗效,为临床慢性乙型肝炎(CHB)抗病毒治疗提供参考依据。方法回顾性分析369例CHB患者的资料,根据治疗方案及基线ALT水平分组,分析治疗48周后不同治疗方案、不同基线ALT水平的病毒学应答率、HBeAg转阴率、HBsAg下降情况,评估治疗效果。结果①病毒学应答情况:治疗48周后恩替卡韦组在基线ALT≤5倍正常值上限(ULN)(组1)、5～10×ULN(组2)、>10×ULN(组3)的病毒学应答率分别为83.3%、91.4%、95.5%,α干扰素组则分别为19.7%,40%,42.9%,不同治疗方案之间及不同ALT水平组之间对比差异均有统计学意义(P<0.05)。②HBeAg转阴情况:恩替卡韦组的组1、组2、组3在治疗48周后的HBeAg转阴率分别为8.3%、16.7%、35.5%,而α干扰素组分别为1.8%、41.9%、38.1%,对比同一治疗方案不同ALT分组,差异具有统计学意义(P<0.05),而分析同一ALT分组不同治疗方案,仅在组2中两种治疗方案的HBeAg转阴率差异有统计学意义(P<0.05)。③HBsAg下降情况:恩替卡韦组在基线ALT≤5×ULN组和>5×ULN组的HBsAg小于200 U/mL率分别为2.5%、13.8%,两者差异无统计学意义,α干扰素组则分别为30.6%、33.3%,差异无统计学意义(P>0.05),而同一ALT分组两种治疗方案的HBsAg小于200 U/mL率的差异均具有统计学意义(P<0.05)。结论治疗48周后,恩替卡韦组在各个ALT组均较α干扰素组有更高的病毒学应答率。在基线ALT5～10×ULN组中,α干扰素组的HBeAg转阴率高于恩替卡韦组。对于HBsAg下降情况,α干扰素组在各个ALT组均较恩替卡韦组有更好的效果,而同一治疗方案不同ALT组中,基线高ALT水平(ALT>5×ULN)组的疗效均优于基线低ALT水平(ALT≤5×ULN)组。因此,建议基线ALT水平在5～10×ULN的患者优先选择α干扰素治疗,而基线ALT水平≤5×ULN、>10×ULN的患者选用恩替卡韦治疗。
Objective To evaluate the therapeutic effects of entecavir (ETV) and interferon-α(IFN-α) treatments for 48 weeks for chronic hepatitis B (CHB) in patients with different baseline alanine aminotransferase (ALT) levels. Methods We retrospectively analyzed the data of 369 CHB patients receiving ETV and IFN-α treatments for 48 weeks. We compared the virological response rates, HBsAg clearance, and HBsAg reduction between the patients receiving ETV and IFN-α treatments with different baseline ALT levels [≤5×upper limits of normal (ULN) level (subgroup 1), 5-10×ULN (subgroup 2), and >10× ULN (subgroup 3)]. Results In patients receiving ETV treatment, the virological response rate was 83.3% in subgroup 1, 91.4% in subgroup 2, and 95.5% in subgroup 3, as compared with 19.7%, 40%, and 42.9% in the 3 subgroups with IFN-α treatment, respectively, showing significantly differences both among different subgroups with the same treatment and between the same subgroup with different treatments (P<0.05). HBeAg clearance rates in the 3 subgroups were 8.3%, 16.7% and 35.5% in patients with ETV treatment and were 1.8%, 41.9%, and 38.1% in patients with IFN-α treatment, respectively, showing significant differences among the 3 subgroups with the same treatment (P<0.05);in the same subgroups with different treatments, the rates differed significantly only between subgroups 2 (P<0.05). In ETV group, the rate of HBsAg reduction to below 200 IU/ml was 2.5% in subgroup 1 and 13.8% in subgroup 2, showing no significant difference between the two subgroups;in IFN-α group, the rates were also similar between subgroups 1 and 2 (30.6% vs 33.3%, P>0.05);but the rates differed significantly between the same subgroups with different treatments (P<0.05). Conclusion In all the subgroups with different baseline ALT levels, ETV treatment for 48 weeks results in significantly higher virological response rates than IFN-α treatment in patients with CHB. In patients with a baseline ALT of 5-10 ×ULN, IFN-α can result in a higher HBeAg clear
