Optimization of the immunologic diagnostic criteria for rheumatoid arthritis

Abstract

Objective To optimize the immunologic diagnostic criteria of rheumatoid arthritis commonly used in clinical,to find methods to diagnose rheumatoid arthritis quickly,accurately and economically.Methods The levels of RF,CRP,ESR,anti-CCP,AKA,CP I,anti-MCV in blood of the patients with rheumatoid arthritis were simultaneously measured, and their sensitivity and specificity was compared.Results The sensitivity and specificity of antiMCV was 76.8% and 90.6% ,anti-CCP 67.2% and 90.3% ,AKA 75.2% and 84.7% ,RF 72.8% and 79.1%.The sensitivity and specificity of them were higher.The specificity of GPI(92.1% ) was high,but the sensitivity of it (46.4% )was low.The sensitivity and specificity of other criteria were low.Conclusion anti-MCV,anti-CCP,AKA and RF could be preferentially used in the diagnosis,therapy and monitor of curative effect of rheumatoid arthritis.
