摘要 目的:了解慢性HBV感染患者中Th1、Th2细胞的百分率及其与肝炎活动指标、免疫球蛋白水平和病毒复制的关系。方法:通过免疫荧光染色技术标记乙肝患者和正常对照者外周血单个核细胞表面CD4分子和细胞内IFN-γ或IL-4分子,用流式细胞术分析标记结果。结果:慢性HBV感染患者Th1细胞数量和Th1/Th2细胞的比值明显低于正常人(13.1±4.3vs18.7±10.0,P<0.05,6.3±3.7vs12.9±5.9,P<0.01),以HBV慢性携带组(8.1±0.6)和慢性肝炎轻度组(12.2±3.4)降低最为明显;而Th2细胞的数量(%)在慢性肝炎组则明显增加(2.9±2.2vs1.6±0.8,P<0.05)。T辅助细胞亚群的变化与肝功能和病毒复制指标的相关性不显著。结论:慢性HBV感染患者存在着Th1、Th2细胞数量和Th1/Th2细胞比例的异常,炎性损伤不明显时以Th2细胞比率的增加为主,此种异常可能导致患者的肝脏损伤程度的差异及疾病持续时间的不同。
