摘要 目的探讨6-磷酸葡萄糖异构酶抗原(GPI)及其联合抗环瓜氨酸肽抗体(抗CCP)和抗角蛋白抗体(AKA)的检测在自身类风湿性关节炎(RA)的诊断意义。方法应用酶联免疫固相吸附试验(ELISA)和间接免疫荧光法,对65例RA患者,55例非RA相关疾病患者血清中GPI、抗环瓜氨酸肽抗体(抗CCP)和抗角蛋白抗体(AKA)水平进行检测,设本院门诊健康体检73例为正常对照。结果RA患者GPI、抗CCP和AKA阳性检出率分别为86.2%、70.8%、33.8%,若抗CCP联合AKA检测,阳性率可提高到73.8%;联合3个指标检测,RA诊断阳性率为95.4%,临床符合率高达91.2%。结论GPI是协助诊断RA的一个新的特异性血清学指标,同时结合抗CCP抗体和AKA的检测可以提高RA阳性诊断率,适合在各级实验室推广使用。
