摘要 目的探讨抗突变型瓜氨酸波形蛋白(MCV)抗体检测在类风湿关节炎(RA)诊断中的临床意义。方法选择RA患者(RA组)、其他自身免疫病患者(AD组)、健康查体者(对照组)各63例,均采用ELISA法定量检测抗MCV抗体和抗环瓜氨酸肽(CCP)抗体,用速率散射免疫比浊法检测类风湿因子(RF)-IgM,用四格表计算抗MCV抗体、抗CCP抗体和RF-IgM诊断RA的敏感性、特异性、阳性预测值及阴性预测值。结果 RA组抗MCV抗体、抗CCP抗体与RF-IgM阳性率均显著高于AD组和对照组(P均<0.01);抗MCV抗体的诊断敏感性和特异性均显著高于RF-IgM(P均<0.05),其中敏感性显著高于抗CCP抗体(P<0.05);抗MCV抗体诊断RA的阳性预测值和阴性预测值均略高于抗CCP抗体及RF-IgM(P均>0.05)。结论抗MCV抗体对RA有较高的诊断价值,且检测方法简便、快捷,可作为筛查和辅助诊断RA的重要指标。
