    • The present invention addresses the problem of providing a method whereby disease activity of rheumatoid arthritis is evaluated reliably and with good sensitivity by a simple method, and a kit for use in the method. The present invention furthermore provides a method for accurate diagnosis of polymyalgia rheumatica and relapsing polychondritis, which are similar rheumatic diseases, a method for differentiating rheumatoid arthritis, and a kit for use in the same. The present invention provides a Jacalin-binding O-linked oligosaccharide epitope as a negative marker for diagnosing rheumatoid arthritis, and enables more accurate assessment of disease condition by more objectively determining disease activity of rheumatoid arthritis using the amount of variation of a value obtained by multiplying the amount of MMP-3 in the blood or the amount of bound MMP-3 and ABA, ACA, or ACG in the blood by the reciprocal of the amount of bound MMP-3 and Jacalin in the blood. Through the discovery that an LEL or STL-reactive sugar chain on MMP-3 in the blood is a sugar chain marker for diagnosing polymyalgia rheumatica and relapsing polychondritis, the present invention also provides a method for accurate diagnosis of polymyalgia rheumatica and relapsing polychondritis. The present invention furthermore provides a method for accurate diagnosis of rheumatoid arthritis capable of differentiating between similar rheumatic diseases, by measuring the ratio of the amount of LEL or STL bound on MMP-3 and the amount of Jacalin, ACG, or the like bound on MMP-3 in the blood.
    • 本发明解决了提供一种方法的问题,该方法通过简单的方法可靠且以良好的灵敏度评估类风湿性关节炎的疾病活性,以及​​用于该方法的试剂盒。 本发明还提供了用于准确诊断风湿性多肌痛和类风湿性疾病的复发性多软骨炎的方法,用于区分类风湿性关节炎的方法和用于其的试剂盒。 本发明提供了一种结合Jacalin的O-连接寡糖表位作为诊断类风湿性关节炎的阴性标记物,并且通过使用通过将类风湿性关节炎相关的数值的变化量更加客观地确定类风湿性关节炎的疾病活性,能够更准确地评估疾病状态 血液中MMP-3的量或血液中结合的MMP-3和ABA,ACA或ACG的量由血液中结合的MMP-3和Jacalin的量的倒数决定。 通过发现血液中MMP-3上的LEL或STL-反应性糖链是诊断风湿性多动脉炎和复发性多软骨炎的糖链标志物,本发明还提供了用于准确诊断风湿性多肌痛和复发性多软骨炎的方法。 本发明进一步提供了一种通过测量与MMP-3结合的LEL或STL的量与结合的Jacalin,ACG等的量之比来准确诊断能够区分类风湿性疾病的类风湿性关节炎的方法 MMP-3在血液中。
