摘要 目的:探讨抗环瓜氨酸肽(CCP)抗体及类风湿因子(RF)对老年起病的类风湿关节炎(EORA)诊断的特异性和敏感性,探讨其与EORA病情活动性之间的相关性。方法:对26例EORA患者、68例非老年起病的类风湿关节炎(NEORA)患者及35例正常老年人的血清进行了抗CCP抗体及RF的测定,并对其与EORA病情活动性之间的关系进行了分析。结果:26例EORA患者中,抗CCP抗体及RF的阳性率分别为65.4%(17/26)及61.5%(16/26)。68例NEORA患者中,抗CCP抗体及RF的阳性率分别为41.2%(28/68)及77.9%(53/68)。35例正常老年人中,仅有1例检测到抗CCP抗体,有2例检测到RF低滴度阳性。抗CCP抗体及RF在26例EORA患者中的敏感性分别为65.4%及61.5%,特异性分别为97.1%及94.3%。抗CCP抗体在EORA组的敏感性显著高于NEORA组,而RF在NEORA组的敏感性则显著高于EORA组(P<0.05)。以28处关节疾病活动度积分(DAS28)来评价EORA患者的病情活动性,在EORA患者中,抗CCP抗体阳性组及RF阳性组患者的病情活动性均分别显著高于各自阴性对照组。结论:抗CCP抗体及RF有助于EORA的诊断及病情活动性判断。
