摘要 目的:评价γ-干扰素释放试验T-SPOT.TB检测外周血结核分枝杆菌抗原特异性γ-干扰素水平在肺外结核病诊断中的临床意义。方法:选取肺外结核患者(肺外结核组,30例)和健康人(健康对照组,31例)外周血单个核细胞(PBMC),利用结核分枝杆菌特异抗原ESAT-6和CFP-10与PBMC共同培养,采用ELISPOT检测培养液中IFN-γ浓度。比较T-SPOT.TB与TST及相关指标TB-AB、ESR、ADA等的结果。结果:T-SPOT.TB检测在肺外结核病中的敏感性是93.3%,高于健康对照组,差异有统计学意义(P<0.05)。两组间TST阳性率比较,差异无统计学意义(P>0.05)。在健康对照组中,T-SPOT.TB检测特异性(93.5%)高于TST(54.8%),结果比较差异有统计学意义(P<0.05)。肺外结核组TB-AB,ESR,ADA水平高于健康对照组,差异有统计学意义(P<0.05)。结论:T-SPOT.TB检测法对肺外结核病诊断特异性高,优于TST试验,其联合TB-AB、ESR、ADA等对于肺外结核病的诊断意义更大。
