The relation of radiographic changes to serum acute-phase proteins and rheumatoid factor in 200 patients with rheumatoid arthritis

Abstract

Radiographic parameters in 200 patients with rheumatoid arthritis (RA) were correlated with laboratory parameters, including hemoglobin (Hb), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), orosomucoid (OROS), immunoglobulin G (IgG), IgM, IgA, and rheumatoid factor (RF). CRP, OROS, and Hb showed a significant association with the severity and progress of radiographic parameters. ESR and WARO showed a significant association with the severity of radiographic parameters in late RA only. IgG, IgM, and IgA did not show any significant correlation with radiographic parameters.
