title: [The comparison of clinical features between early rheumatoid arthritis and established rheumatoid arthritis].
abstract: Clinical features between 69 early RA patients (within a year duration) and 79 established RA patients (more than 3 years duration) were compared retrospectively. There were no significant differences about frequencies of morning stiffness (68.2% vs 54.4%) and rheumatoid nodules (20.2% vs 15.2%) between early RA and established RA. There were also no significant differences between two groups about elevation of ESR (92.8% vs 97.4%), positivity of CRP (97.1% vs 94.9%) and rheumatoid factor (RF) (82.6% vs 93.7%), and Lansbury activity index (AI) (mean 68.8% vs 78.8%). After hospitalization and treatment, all clinical indices (ESR, CRP, RF, AI) improved significantly in both groups. There, however, were clinically more "marked improvement" (39.1% vs 16.4%) and "remission" (8.7% vs none) in early RA group. We conclude that by hospitalization and treatment, clinical improvement can be expected in both early and established RA, but to secure satisfactory improvement, early detection and intervention of RA would be recommended.
