The purpose of this study is to determine whether anti-inflammatory treatment with adalimumab (Humira) reduces endothelial activation in blood vessels in patients with active rheumatoid arthritis. Markers of endothelial activation are assessed in muscle tissue before treatment and after 3 months, and related to other biomarkers and clinical outcomes.
