title: Serum copper and its relationship to clinical symptoms in rheumatoid arthritis.
abstract: Total serum copper and ultrafilterable copper levels in patients with rheumatoid arthritis were determined and related to articular index, erythrocyte sedimentation rate (ESR), and serum iron concentration. Relationships were found between serum copper and ESR, and between ultrafilterable copper and articular index. The relationship between serum copper and serum iron was found to be a drug-dependent.
