科学领域:

临床免疫学和诊断临床免疫学和诊断
自动抗体检测方法自动抗体检测方法
风湿病学和自身免疫性疾病

背景情况:

抗脂抗体 (aPL) 测试对于诊断抗脂综合征 (APS) 是必不可少的.
2023年ACR/EULAR分类标准强调与酶相关的免疫吸收试验 (ELISA) 和特定的阳性值.
越来越多的非ELISA方法在临床实践中需要与传统的ELISA进行比较.

研究的目的:

为了比较和评估ELISA和非ELISA (化学发光免疫测试 - CLIA) 抗脂抗体测试的性能.
评估这些方法在现实世界医院环境中的一致性和临床相关性.
确定测试方法对抗脂综合征分类的影响.

主要方法:

使用ELISA和CLIA测量了抗心脂蛋白 (aCL) 和抗β2糖蛋白I (aß2GPI) 抗体 (IgG和IgM).
在2021年1月至2024年6月期间,对946个样本进行了并行测试.
结果与临床和实验室特征的一致性和关联性进行了比较,包括APS诊断.

主要成果:

总体上,ELISA和CLIA之间的一致性仅在aß2GPI IgG上是可接受的;在aCL IgG/IgM和aß2GPI IgM上观察到的一致性很差.
在APS患者中,对aß2GPI IgG和IgM的一致性是可以接受的,但对aCL IgG和IgM的一致性很差.
与ELISA相比,CLIA在APS患者中显示出显著更高的抗体水平,影响了阳性率和分类.

结论:

在aPL测试中,ELISA和CLIA之间存在大量依赖方法的差异,影响了定量和质量结果.
虽然这两种方法都可以用于APS分类,但测试的选择可能会影响诊断结果.
对aPL结果的临床解释需要仔细考虑所采用的特定测试方法.
