ABSTRACT

Anti-cyclic citrullinated peptide (anti-CCP) antibody is a highly specific biomarker for Rheumatoid Arthritis (RA), and recognized as a predictor of development of RA.[1,2] It had been demonstrated that some HLA-DRB1 alleles, such as shared epitope (SE) alleles, significantly contribute to the positivity of anti-CCP antibody and the susceptibility of anti-CCP antibody-positive RA.[3,4] However, the quantitative effect of HLA-DRB1 alleles on anti-CCP antibody levels in RA patients is controversial.[3,5,6] Therefore, we carried out a large-scale study to study the quantitative effects of HLA-DRB1 alleles on anti-CCP antibody levels in Japanese patients with RA.
