1、南通大学学报(医学版)JournalofNantongUniversity(MedicalSciences)2011:31(6·479·抗突变型瓜氨酸波形蛋白抗体和抗环瓜氨酸肽抗体对类风湿关节炎诊断价值的比较陈相,赵枰,曹兴建,张克霞,郁超,张秀琳(南通大学第二附属医院检验科,南通226001)【摘要】目的:评价抗环瓜氨酸肽(cCP)抗体和抗突变型瓜氨酸波形蛋白抗体(MCV)Xf类风湿关节炎(RA)的诊断价值。方法:用酶联免疫吸附试验(ELISA)~分别测定RA患者47例、其他风湿病患者42例以及健康对照者30例血清中的抗CCP抗体和抗M
2、CV抗体,并应用R0C曲线比较两者对RA的诊断价值。结果:RA组血清抗CCP抗体和抗MCV抗体水平(中位数)分别为120.0U/mL和501.0U/mL,分别与其他风湿病组(分别为12.5U,mL和23.0U/mL)~健康对照组(分别为12.0U,mL和20.5U/mL)比较,差异均有统计学意义(P<0.O1)。抗CCP抗体单项检测、抗MCV抗体单项检测、抗CCP抗体+抗MCV抗体按序列实验联合检测和按平行试验联合检测诊断RA的敏感度分别为68.1%、72.3%、53.2%和83.0%,特异度分别为88.9%、87.5%、91.7%和84
3、.7%,Youden指数分别为0.570、0.598、0.449和0.677。结论:抗MCV抗体同抗CCP抗体一样对RA有较高的诊断价值,以l11.0U/mL为界值点,对RA诊断的正确率更高。联合检测可弥补单项抗体检测造成的RA漏诊,按平行试验联合检测抗MCV抗体和抗CCP抗体对RA的诊断有很大的临床价值。『关键词]抗环瓜氨酸多肽抗体;抗突变型瓜氨酸波形蛋白抗体;类风湿性关节炎[中图分类号】R593.22[文献标志码]A【文章编号]1674—7887(2011)06—0479—03Studyonthediagnosticvalueofan
