| 摘 要： | [摘要] 目的: 建立检测脑脊液中抗INF-γ自身抗体的ELISA方法，并检测结核性脑膜炎患者脑脊液中抗INF-γ自身抗体水平，初步探讨抗INF-γ自身抗体与结核性脑膜炎发病机制的关系。方法：通过对封闭条件、抗原用量等条件进行优化，建立了检测脑脊液中抗INF-γ自身抗体的ELISA检测方法。采用建立的最佳检测条件对21例结核性脑膜炎和6例对照的脑脊液进行了抗INF-γ自身抗体检测。结果：在14例重症结核性脑膜炎患者的脑脊液中测到高滴度的抗INF-γ自身抗体，平均值和阳性比例明显高于正常对照和7例轻症患者(P<0.01)，轻症患者的阳性比例高于正常对照(P<0.05)。结论：检测方法简便、可靠，结核性脑膜炎患者脑脊液中存在抗INF-γ自身抗体，与病情程度相关，对抗INF-γ自身抗体的研究有助于进一步探讨结核性脑膜炎的免疫病理机制。

| Abstract: | [Abstract] Objective To establish an immune enzyme assay for detecting anti-interferon-gamma autoantibody in cerebrospinal fluid(CSF) and to investigate the relationship between anti-IFN-γ autoantibody levels and tuberculosis meningitis. Methods An ELISA was established by optimizing the condition of blocking and concentration of antigen.The cerebrospinal fluid from 21 patients with tuberculosis meningitis were assayed for anti-IFN-γ autoantibody, and was compared with samples from 6 healthy control subjects. Result The median level and positive percentage in the severe cases was higher than mild cases and healthy controls.The positive percentage in mild cases was higher than the healthy controls. Conclusion In this study, anti-IFN-γ autoantibody in the CSF detected by enzyme-linked immunosorbent assay(ELISA)is reliable and simple.The level of anti-IFN-γ autoantibody is significantly elevated and correlated with the pathogenetic condition of tuberculosis meningitis.The further research would promote the understanding about the immunopathogenesis mechanism of the tuberculosis meningitis. |
