title: 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.
