恩替卡韦与阿德福韦酯抑制乙型肝炎调节性T细胞的效价差异

目的:比较恩替卡韦(ETV)与阿德福韦酯(ADV)在抑制慢性乙型肝炎(CHB)患者调节性T细胞(Treg)效价的差异。方法:收集36例CHB患者随机分为ETV及ADV组,分别给予口服ETV 0.5 mg q.d.及ADV 10 mg q.d.;治疗48周,分别于第12、24、36及48周采血检测Treg的含量,使用定量PCR检测其功能因子叉头蛋白p3(Foxp3)mRNA含量,用ELISA检测其细胞因子白介素10(IL-10)及转化生长因子β1(TGF-β1)的含量,并检测乙肝病毒定量(HBVDNA)、肝功能。结果:治疗前两组患者上述指标均不存在统计学差异(P>0.05);治疗后第24、36及48周ETV组Treg含量均显著低于ADV组(P<0.05);ETV组第12、36及48周的Foxp3均低于ADV组;ETV组第48周的IL-10含量低于ADV;ETV组第36及48周的TGF-β1含量低于ADV组(P<0.05);ETV组第12及36周的HBV DNA低于ADV组,且第48周两组的HBV DNA均已降至1000 copies/mL的参考值以内;第12周ETV组的ALT显著低于ADV组,ETV组其余时间点的ALT以及总胆红素均与ADV组不存在统计学差异;相关性分析显示Treg与HBV DNA呈显著正相关性(r=0.785,P=0.016)。结论:在抗HBV效价相当的情况下,ETV抑制调节性T细胞的效价优于ADV。

Comparison of entecavir and adefovir dipivoxil on suppressing for the function of regulatory T cells for patients with chronic hepatitis B

AIM:To observe the effect of entecavir(ETV) and adefovir dipivoxil(ADV)on suppressing for the function of regulatory T cells(Treg) for patients with chronic hepatitis B(CHB). METHODS: Thirty six CHB patients were randomly divided into the ETV and ADV groups.Patients in ETV group were administrated ETV 0.5 mg q.d.,whereas the ones in the ADV group were dosed with ADV 10 mg q.d..All the subjects were treated for 48 weeks and were followed at the end of the 12th,24th,36th and 48th week to collect the periphera...
