摘要 目的研究抗环瓜氨酸肽(CCP)抗体、抗角蛋白抗体(AKA)在老年发病类风湿关节炎(EORA)中的临床意义。方法检测69例EORA患者和42例风湿性多肌痛(PMR)患者中的两种抗体,其中抗CCP抗体采用ELISA法,AKA采用间接免疫荧光(IIF)法检测。结果EORA组两种抗体的阳性率显著高于PMR组(P<0.05),两种抗体诊断EORA的敏感性和特异性分别为:抗CCP抗体(55.1%、94.3%)、AKA(33.3%、91.5%),抗CCP抗体和AKA合用敏感性有所降低,但能使特异性增高至98.3%。结论抗CCP抗体有很高的敏感性和特异性,抗CCP抗体和AKA在EORA组中的阳性率明显高于PMR组,两种抗体联合检测使特异性提高近100%,有利于EORA的鉴别诊断,结合影像学改变,对提高EORA的诊断率也有临床应用价值。
