摘要: 目的 探讨胸水中的脂阿拉伯甘露聚糖(LAM)抗原对结核性胸膜炎的诊断价值,以获取一种诊断结核性胸膜炎的辅助指标。方法 收集胸水标本共96例,其中结核性胸膜炎46例,非结核性胸膜炎50例,采用双抗体夹心酶联免疫吸附试验(ELISA)检测胸水中的LAM抗原。结果 结核性胸膜炎胸水中LAM抗原阳性率为54%,非结核性胸膜炎胸水中LAM抗原阳性率为22%,二者差异有统计学意义(P<0.05)。结论 胸水中LAM抗原检测可作为结核性胸膜炎诊断的一项新指标。

Abstract: Objective To investigate whether the determination of lipoarabinomannan (LAM) antigen in pleural fluid may be used as an indicator for the diagnosis of tuberculous pleurisy. Methods Double antibody sandwich enzymelinked immunosorbent assay(ELISA) was performed to detect LAM antigen in 96 pleural fluid samples (46 patients with tuberculous pleurisy and 50 patients with nontuberculous pleurisy). Results The positive rate of LAM antigen in pleural fluid with tuberculous pleurisy group was 54%, and the positive rate in pleural fluid with nontuberculous pleurisy was 22%. There was a statistical difference between them(P<0.05). Conclusions LAM antigen could be used as a new indicator for the diagnosis of tuberculous pleurisy.
