Anti-cyclic Citrullinated Peptide Antibodies in Early Rheumatoid Arthritis
Japanese Journal of Rheumatism and Joint Surgery
Objective: Anti-cyclic citrullinated peptide (anti-CCP) antibody has been known to be a specific autoantibody of rheumatoid arthritis (RA). The objective of this study was to examine the availability of anti-CCP antibody in early RA. Methods: 109 patients with RA were included in this study, and thirty of them had early RA, that was within one year of onset. Anti-CCP antibody and rheumatoid factor (RF) were measured in all serum samples, and their sensitivity as RA markers was analyzed duringdoi:10.11551/jsjd1982.25.19 fatcat:u7vpc5yzizaizbpz46fr3zqlma
