我们之前已经开发了一种基于尿液中分枝杆菌阿拉伯甘露聚糖(LAM)检测的结核病诊断试验。这种方法依赖于费力的浓缩步骤。我们现在已经开发了一种基于磁性免疫分析平台的易于执行的检测方法,利用高亲和力的单抗检测尿液中的LAM。与常规的酶联免疫吸附试验相比,该方法的分析灵敏度提高了50-100倍。在一项针对HIV阴性的结核患者(n=17)和健康对照(n=22)的初步研究中,该检测的敏感性为82%,特异性为100%。这与使用多克隆抗LAM抗体进行商业检测的一系列研究形成了鲜明的对比,在这些研究中,HIV阴性结核病患者的检测敏感性非常低。
We have previously developed a diagnostic test for tuberculosis based on detection of mycobacterial lipoarabinomannan (LAM) in urine. The method depended on a laborious concentration step. We have now developed an easy to perform test based on a magnetic immunoassay platform, utilizing high avidity monoclonal antibodies for the detection of LAM in urine. With this method the analytical sensitivity of the assay was increased 50-100-fold compared to conventional ELISA. In a pilot study of HIV-negative patients with microbiologically verified TB (n=17) and healthy controls (n=22) the sensitivity of the test was 82% and the specificity 100%. This is in stark positive contrast to a range of studies using available commercial tests with polyclonal anti-LAM Abs where the sensitivity of the tests in HIV-negative TB patients was very low.
