Abstract

目的:通过比较抗环瓜氨酸肽抗体(Anti-CCP)、抗角蛋白抗体(AKA)和类风湿因子(RF)在类风湿关节炎(RA)中的敏感性及特异性,来探讨三者联合检测在RA中的意义.方法:应用酶联免疫吸附试验(ELISA)检测80例RA患者、60例非RA患者抗环瓜氨酸抗体和抗角蛋白抗体,同时应用乳胶凝集试验检测RF,对结果进行统计比较.结果:Anti-CCP和AKA的检测灵敏度与RF接近,但二者的特异性均高于RF.Anti-CCP和AKA在RA患者中的检出率分别为42.5%和43.8%,但在RF阳性的RA患者中,Anti-CCP和AKA的检出率为71.1%和68.4%,显著高于RF阴性组的检出率16.7%和21.4%(P<0.01).结论:Anti-CCP和AKA是检测RA的一项特异性较高的血清学指标,且可以作为RA的早期诊断指标.
