摘要 目的:探讨GPI抗原及RF联合检测在类风湿关节炎中的诊断价值。方法:采用横断面研究,110例RA患者,47例其他风湿性疾病患者,32例非风湿性疾病患者,用ELISA方法检测血清中的GPI抗原,免疫比浊法测RF,并比较GPI抗原、RF抗体及串联检测对于RA的敏感性和特异性,并分析两者之间的相关性。结果:GPI抗原、RF在RA组的检测结果明显高于非RA风湿性疾病组和非RA对照组,经t检验P【0.01;GPI抗原对诊断RA敏感性不如RF(GPI71.8%,RF81.8%),但有很高的特异性(GPI91.1%,RF82.3%),与RF串联检测对诊断RA的有更高特异性(97.4%),较单独检测RF有更高的阳性预测值(PPV)97.2%,阴性预测值(NPV)有所下降65.2%;GPI抗原与RF两者之间呈正相关。结论:相对于RF,GPI抗原对RA具有更高的特异性,它与RF抗体的串联检测能提高RA的早期诊断率。
