摘要: 目的 观察慢性乙型肝炎患者免疫功能的变化,探讨患者干扰素γ(IFN-γ)、白细胞介素10(IL-10)和CD19+与乙型肝炎病毒(HBV)DNA载量的关系。 方法 采用酶联免疫吸附试验(ELISA)和流式细胞术检测76例慢性乙型肝炎患者和30名正常人血清IFN-γ、IL-10和外周血CD19;用荧光定量聚合酶链反应(PCR)检测慢性乙型肝炎患者血清HBV DNA拷贝数。 结果 HBV DNA低拷贝组、高拷贝组的IFN-γ与HBV DNA阴性组比较明显下降,IL-10、CD19与HBV DNA阴性组比较明显增高;IFN-γ水平与HBV DNA载量呈负相关(r=-0.311,P<0.05),IL-10和CD19的水平与HBV DNA载量呈正相关(r=0.350,P<0.05;r=0.321,P<0.05)。 结论 HBV感染者存在免疫功能调节紊乱,IFN-γ、IL-10和CD19水平的检测可作为乙型肝炎相关疾病炎症活动的观察指标。

Abstract: Objective To observe the change of immune function in patients with chronic hepatitis B, and to investigate the relationship of interferon-gamma(IFN-γ), interleukin 10 (IL-10) and CD19 with hepatitis B virus(HBV) DNA load.   Methods By enzyme-linked immunosorbent assay (ELISA) and flow cytometry, the serum IFN-γ, IL-10 and peripheral blood CD19 levels of 76 patients with chronic hepatitis B and 30 healthy subjects were determined. By fluorescence quantitative polymerase chain reaction (PCR), serum HBV DNA copy number was determined. Results The IFN-γ levels in HBV DNA low copy group and high copy group decreased significantly compared with those in HBV DNA negative group. Their IL-10 and CD19 levels increased significantly compared with those in HBV DNA negative group. The IFN-γ levels were correlated negatively with the HBV DNA load (r=-0.311,P<0.05), and the IL-10 and CD19 levels were correlated positively with the HBV DNA load (r=0.350,P<0.05; r=0.321, P<0.05).  Conclusions The patients have immune function adjustment disorder. The IFN-γ, IL-10 and CD19 levels can be monitoring indices for the inflammatory of hepatitis B related diseases.
