摘要 目的观察替比夫定治疗HBeAg阳性慢性乙肝患者对HBV特异性T细胞细胞亚群的影响。方法选取2013年12月至2015年1月在我院接受替比夫定治疗的HBeAg阳性慢性乙型肝炎患者10例,其中完全应答(CR)组3例,部分应答(PR)组4例,无应答(NR)组3例,观察治疗后HBV特异性细胞毒T淋巴细胞(CTL)水平及HBV DNA、干扰素-γ(IFN-γ)、肿瘤坏死因子-α(TNF-α)等的变化。结果三组患者HBV DNA水平随着治疗时间的延长而下降,CR组和PR组差异有统计学意义(F=17.21,P<0.05)。患者HBV特异性CTL水平随着治疗时间的延长而增加,对于CR组,强烈的增殖反应在12周时达到最高,持续反应到36周(t=28.27,P<0.05),对于PR组,强烈的增殖反应出现在12周(t=15.57,P<0.05),而NR组则无明显的增殖反应(P=0.286)。患者治疗后第3个月IFN-γ和TNF-α含量较治疗开始时高,差异有统计学意义(F_(IFN-γ)=23.43,F_(TNF-α)=18.27,P<0.05),第6个月、第12个月IFN-γ和TNF-α含量均高于治疗第3个月,差异有统计学意义(F_(IFN-γ)=27.35,F_(TNF-α)=16.17,P<0.05);第6个月和第12个月IFN-γ、TNF-α含量比较,差异无统计学意义(P>0.05)。结论替比夫定治疗HBeAg阳性慢性乙型肝炎患者能有效抑制HBV的复制,降低HBeAg水平,HBV特异性细胞毒T淋巴细胞功能随着治疗的延长而增强,治疗后HBeAg血清学转换的发生与HBV特异性细胞毒T淋巴细胞水平升高有关。 Objective To observe the influence of antiviral therapy on cellular immune responses during sus tained Telbivudine treatment. Methods Ten HBeAg positive CHB patients were divided into the CR group (3 cases), PR group (4 cases) or NR group (3 cases) respectively and treated with Telbivudine. After treatment for one year, the levels of HBV specific cytotoxic CTL, IFN-γ and TNF-α in three groups were compared. Results The effectively-treated patients showed an augmented proliferative response of HBV- specific T-cells to hepatitis B core antigen (HBcAg), and the induction of eytokines, such as IFN-γ and TNF-α release at the site of infection compared to nomresponsive patients. Conclusion Enhanced HBV-specific T-cell reactivity to Telbivudine therapy, which peaked at treatment week 12, was confined to a sub- group of effectively-treated patients who achieved greater viral suppression.
