摘要 目的观察阿德福韦酯对慢性乙型肝炎患者外周血HBV-DNA和Th1/Th2细胞因子的调节作用。方法选择40例轻中度慢性乙型肝炎患者作为治疗组,予阿德福韦酯10mg口服,每日1次,连续服用12周,检测治疗前和治疗12周后患者外周血HBV-DNA和白细胞介素4(IL-4)、干扰素-γ(IFN-γ)含量的变化,并根据HBV-DNA复制指标及HBeAg/HBeAb转换情况将治疗组分为治疗有效组与治疗无效组。另选择30例正常健康体检者作为对照组。结果与对照组比较,治疗组患者外周血培养上清单个核细胞(PBMC)中IL-4水平明显上升,而IFN-γ水平明显下降(P均小于0.01)。治疗12周后患者外周血培养上清PBMC中IL-4水平和HBV-DNA含量明显下降,而IFN-γ水平明显上升(P<0.05或P<0.01)。治疗有效组外周血培养上清PBMC中IFN-γ水平明显高于治疗无效组,IL-4水平和HBV-DNA含量则明显低于治疗无效组(P均小于0.01)。结论慢性乙型肝炎患者存在Th1/Th2平衡失调,阿德福韦既能抑制HBV-DNA复制又能调节Th1/Th2细胞因子比例平衡,使免疫反应由Th2型向Th1型逆转。
