  Purpose
This study is being conducted to validate various biomarkers in patients with RA with varying levels of disease severity. Subjects with a diagnosis of rheumatoid arthritis (RA) will be included as controls. The sudy will measure the baseline levels and the intra- and inter-subject variability of exhaled nitric oxide (NO) in patients with inactive/mild and moderate/severe RA on stable therapy or during a course glucocorticoids. In addition exhaled NO levels will be correlated with intra-articular inflammation (power Doppler ultrasonography) as well as markers of systemic inflammation (CRP, ESR).

Condition Intervention
Rheumatoid Arthritis Osteoarthritis Procedure: Power doppler ultrasonography Procedure: High frequency ultrasonography Procedure: Exhaled nitric oxide assessment

Study Type: Observational
Study Design: Time Perspective: Prospective
Official Title: An Enabling Study to Investigate the Correlation of Biomarkers of the Activity of Inducible Nitric Oxide Synthase (iNOS) With Disease Activity and Treatment Response in Patients With Rheumatoid Arthritis(RA)
