摘要 目的研究慢性病毒性乙型肝炎患者T细胞亚群、IL-18、IFN-γ变化与其血清HBV DNA的水平,探讨病毒复制程度与机体免疫功能的关系。方法应用流式细胞仪直接免疫荧光法检测60例乙型肝炎病毒感染者、25例健康对照外周血T细胞亚群百分率;用ELISA法检测血清中IL-18、IFN-γ水平;用荧光定量PCR法检测乙型肝炎感染者血清HBV DNA。结果根据HBV感染者血清中HBV DVA载量的高低,将它们分为低拷贝组[(103~104)copy/mL]、高拷贝组[(>104~108)copy/mL]以及DNA阴性组(<103copy/mL)。HBV感染者外周血CD4+T细胞百分率及CD4+/CD8+比值较健康对照组明显减低,且随着HBV DNA载量的增加,CD4+T细胞百分率及CD4+/CD8+比值降低更明显。CD8+T细胞百分率较健康对照组明显升高,乙型肝炎患者IL-18、IFN-γ表达水平明显高于健康对照组,且随着HBV DNA载量的增加,IL-18、IFN-γ增加更明显。结论慢性病毒性乙型肝炎患者存在免疫调节紊乱,HBV DNA复制增加,进一步加重乙型肝炎病毒感染者T细胞亚群和细胞因子的失衡,CD4+/CD8+比值、血清IL-18、IFN-γ的动态变化可及时提示HBV感染者机体免疫功能的变化。
