摘要 目的探讨类风湿因子(RF)、抗角蛋白抗体(AKA)及抗环瓜氨酸多肽(CCP)抗体联合检测对类风湿性关节炎(RA)的临床诊断价值。方法对83例RA和106例非RA患者用速率散射比浊法检测RF,间接免疫荧光染色法检测AKA,酶联免疫吸附法检测抗CCP抗体,并对3种指标检测进行比较分析。结果3种抗体单独检测对RA诊断的敏感性、特异性分别是:RF为71.1%、74.5%,AKA为49.4%、95.3%,抗CCP抗体为65.1%、94.3%;不同方式联合检测对RA诊断的敏感性、特异性分别是RF+AKA为34.9%、97.2%,RF+抗CCP抗体为45.8%、98.1%,RF+AKA+抗CCP抗体为28.9%、100%;RF在AKA、抗CCP抗体分别阴性的RA患者中检出率分别为28.6%和34.5%;AKA和抗CCP抗体在RF阴性的RA患者中分别有45.8%和62.5%的阳性率。结论单独检测RF对RA诊断的敏感性最高,特异性最高的是AKA,抗CCP抗体有较高的的敏感性及特异性,3种指标各有优点,可互为补充,联合检测RF、AKA及抗CCP抗体可提高对RA诊断的特异性,有助于早期RA的诊断。
