Abstract

Objectives. To assess the ability of a multi-biomarker disease activity (MBDA) score to track clinical response in patients with rheumatoid arthritis (RA) treated with different TNF inhibitors. Methods. The study included 147 patients who had received adalimumab, etanercept, or infliximab for a year or more, during routine clinical care at the University Hospital of Occupational and Environmental Health, Japan. MBDA scores and clinical measures of disease activity were evaluated at baseline and, after 24 weeks (N = 84) and 52 weeks of treatment. Relationships between the changes (Δ) in MBDA score and changes in clinical measures or EULAR response categories were evaluated. Results. The median disease activity was 5.7 by DAS28-ESR and 64 by MBDA score at baseline, and decreased significantly with treatment. Δ MBDA scores over 1 year correlated with Δ DAS28-ESR (r = 0.48) and Δ DAS28-CRP (r = 0.46). Linear relationships between Δ MBDA scores and Δ DAS28-ESR or Δ DAS28-CRP were not signifi cantly diff erent between TNF inhibitors. The MBDA scores declined significantly more in good responders (median change: - 29) than moderate (– 21), and more in moderate than in non-responders (+ 2), by the EULAR criteria. Conclusions. MBDA scores tracked disease activity and treatment response in patients with RA treated with three TNF inhibitors. The relationships between Δ MBDA scores and Δ DAS28-ESR or Δ DAS28-CRP were consistent across the three TNF inhibitor groups.
