摘要 目的评价抗环瓜氨酸肽抗体(抗CCP抗体)、葡萄糖-6-磷酸异构酶(GPI)和抗角蛋白抗体(AKA)单项或联合检测在类风湿关节炎(RA)早期诊断中的作用。方法收集47例我院住院的RA患者和45例同时期入住我院的非RA患者作为对照人群的血清,进行抗CCP抗体、GPI和AKA检测。结果抗CCP抗体、GPI、AKA抗体诊断RA的灵敏度分别为85. 1%,85. 1%和69. 5%,诊断RA的特异性分别为97. 8%,95. 6%和91. 1%。抗CCP抗体对RA的灵敏度较AKA高,差异有统计学意义(P<0. 05),抗CCP抗体与GPI的特异性对比,差异无统计学意义(P>0. 05),而抗CCP抗体对于RA诊断特异性高于AKA,差异有统计学意义(P<0. 05)。抗CCP抗体的阳性预测值最高,阴性预测值以抗CCP抗体、GPI、AKA三者联合检测较好。Youden index亦显示三者联合检测较单独检测抗CCP抗体、GPI或AKA效果好。结论抗CCP抗体、GPI对RA具有较好的灵敏度和高度的特异性,联合检测抗CCP抗体、GPI和AKA可作为早期RA患者及GPI阴性RA患者的早期诊断指标。
