Abstract: Objective To explore the value of human leucocyte antigen-DR53 (HLA-DR53),anti-Sa antibody and anti-cyclic citrullinated peptide antibody(anti-CCP) factors combination in rheumatoid arthritis.Methods 170 patients with rheumatoid arthritis and 50 healthy individuals in the hospital were chosen.The levels of HLA-DR53 by PCR-SSP,the levels of anti-Sa and anti-CCP by ELISA,compared their diagnostic value by consistency analysis and joint detection analysis.Results The sensibility of anti-Sa,HLA-DR53 and anti-CCP in RA were 44.07％ (P =0.00,x2 =165.214),68.65 ％ (P =0.00,x2 =9.837) and 79.45 ％ (P=0.00,x2=48.028).Consistency analysis in RA,HLA DR53,anti-CCP and anti-Sa highly consistent,OR were 3.94,38.6 and 184.52.The sensitivity and Youden index of anti-CCP were the highest.The sensitivity of anti Sa and anti-CCP parallelled was 88.51 ％.The sensitivity of HLA-DR53 and anti-CCP parallelled was 93.56％,and the spe cificity of anti-Sa and anti-CCP of RA were 100％.Conclusion There is a certain correlation between HLA-DR53,anti-Sa and anti-CCP antibody,which are related risk factors of RA,co-detection will improve the diagnosis of RA.
