摘要 目的评价类风湿关节炎(RA)患者的血清学辅助诊断指标:抗突变型瓜氨酸波形蛋白(anti-mutated citrullinated vimentin,anti-MCV)抗体、抗环瓜氨酸多肽(anti-cyclic citrullinated peptides,anti-CCP)抗体和类风湿因子(rheumatoid factor,RF)的临床意义。方法用ELISA法测定76例RA患者、35例其他自身免疫性疾病患者和40例健康体检者血清抗MCV抗体、抗CCP抗体和RF,计算单项或联合检测的敏感性和特异性,绘制ROC曲线,计算ROC曲线下面积。结果单指标检测,抗MCV抗体对RA的敏感性为84.21%(64/76),特异性为96.00%(72/75),优于抗CCP抗体及RF(均P<0.01)。抗MCV抗体的ROC曲线下面积最大(面积0.966,95%可信区间0.940-0.992),临床诊断效能优于抗CCP抗体及RF。三指标联合检测敏感性可提高至94.74%,但以抗MCV抗体和抗CCP抗体两项联合检测的敏感性和特异性之和最大。结论抗MCV抗体为一高度敏感的新的RA诊断血清学标志物,其与抗CCP抗体和RF联合检测,对于筛查和辅助诊断早期RA有重要意义。
