摘  要:目的比较聚乙二醇干扰素α-2a联合恩替卡韦与恩替卡韦单药治疗HBeAg阳性慢性乙型肝炎患者的疗效。方法回顾分析2012年12月至2013年12月治疗的58例HBeAg阳性慢性乙型肝炎患者临床资料。其中29例口服恩替卡韦0.5 mg/次、1次/d,共72周(对照组);29例口服恩替卡韦0.5 mg/次、1次/d,共72周,聚乙二醇干扰素α-2a 180 μg每周1次皮下注射,共48周(观察组)。每12周检测乙肝五项标志物和HBV DNA、血清生化。完成72周随访的患者共54例,观察组26例,对照组28例。结果在治疗第24、48及72周,观察组和对照组的ALT复常率[72%(21/29)与93%(27/29),χ^2=2.104;90%(26/29)与97%(28/29),χ^2=0.269;90%(26/29)与97%(28/29),χ^2=0.269)]、HBV DNA阴转率[31%(8/26)与46%(13/28),χ^2=1.391; 62%(16/26)与57%(16/28),χ^2=0.108;77%(20/26)与75%(21/28),χ^2=0.027]、HBeAg阴转率[12%(3/26)与25%(7/28),χ^2=0.850;31%(8/26)与32%(9/28),χ^2=0.012;46%(12/26)与36%(10/28),χ^2=0.609]及HBsAg滴度[(3.63±0.45)与(3.36±1.18) log10 IU/ml,t=-1.066;(3.45±0.43)与(3.23±1.15) log10 IU/ml,t=-0.915;(3.36±0.58)与(2.88± 1.28) log10 IU/ml,t=-1.762],差异均无统计学意义(均P〉0.05)。58例患者中,15例(26%)为HBeAg/抗-HBe双阳性,与HBeAg单阳性患者比较,其基线HBV DNA水平低[(5.07±1.50)与(6.40±1.47)log10 IU/ml,t=2.858,P=0.006]、HBeAg滴度低[14(4~45)与732(296~1 012)S/CO,Z=-5.031,P=0.000];在不同时间点,HBeAg/抗-HBe双阳性患者HBV DNA阴转率均高于HBeAg单阳性患者,在第24、72周差异有统计学意义[ 10/15与26%(10/39), χ^2=7.819, P=0.005; 15/15与69%(27/39),χ^2=4.287,P=0.038]。HBeAg/抗-HBe双阳性患者HBeAg阴转率均较HBeAg单阳性患者高,在第12、48周差异有统计学意义[6/15与10%(4/39),χ^2�Objective To evaluate the efficacy of pegylated interferon α-2a and entecavir (ETV) combination therapy for patients with HBeAg positive chronic hepatitis B(CHB). Methods Fifty eight HBeAg positive CHB patients were assigned to two groups: 29 patients received ETV 0.5 mg daily for 72 weeks (ETV group) and 29 patients received ETV and pegylated interferon α-2a 180 μg weekly for 48 weeks followed by ETV alone for 24 weeks (combination group). Serum samples were collected from all patients every 12 weeks for assessment of biochemical, virological and serological responses to treatment.Results Fifty four patients completed the 72-week study, including 28 in ETV group and 26 in combination group. There were no significant differences in week 24, week 48 and week 72 of ALT normalization [72%(21/29) vs. 93%(27/29), χ^2=2.104; 90%(26/29) vs. 97%(28/29), χ^2=0.269; 90%(26/29) vs. 97%(28/29), χ^2=0.269], HBV DNA undetectable rate [31%(8/26) vs. 46%(13/28), χ^2=1.391; 62%(16/26) vs. 57%(16/28), χ^2=0.108; 77%(20/26) vs. 75%(21/28), χ^2=0.027], HBeAg loss rate[12%(3/26) vs. 25%(7/28), χ^2=0.850; 31%(8/26) vs. 32%(9/28), χ^2=0.012; 46%(12/26) vs. 36%(10/28), χ^2=0.609] and HBsAg levels(log10 IU/ml)(3.63±0.45 vs. 3.36±1.18, t=-1.066; 3.45±0.43 vs. 3.23±1.15, t=-0.915; 3.36±0.58 vs. 2.88± 1.28, t=-1.762)between two regimens (all P〉0.05). Among 58 patients, 15 were HBeAg and anti-HBe double-positive (26%)and 43 were HBeAg mono-positive patients. The baseline HBV DNA level [(5.07±1.50) vs. (6.40±1.47) log10 IU/ml, t=2.858, P〈0.05] and HBeAg titer [14(4-45) vs. 732(296-1 012)S/CO, Z=-5.031, P=0.05] in double-positive patients were lower than those in mono-positive patients. The HBV DNA undetectable rate of double-positive patients was significantly higher than that of mono-positive patients in 24 weeks [10/15 vs. 26%(10/39), χ^2=7.819, P〈0.05] and 72 weeks [15/15 vs. 69%(27/39�
