Publication number: 20170336413Abstract: A method of evaluating disease activity of rheumatoid arthritis with good sensitivity by a simple method, and a kit for use in the method. It 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.Type: ApplicationFiled: October 29, 2015Publication date: November 23, 2017Applicants: NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGY, KEIO UNIVERSITY, GLYCOBIOMARKER LEADING INNOVATION CO.
