Predictors of Fatigue in Rheumatoid Arthritis Patients in Remission or in a Low Disease Activity State.

Objective: Fatigue is a frequently occurring symptom in patients with rheumatoid arthritis (RA). Our aims were to assess the level of reported fatigue in RA patients who had achieved remission or low disease activity after 6 months of treatment with disease-modifying antirheumatic drugs (DMARDs), and to explore associations between fatigue and demographics, disease activity, and other patient-reported outcomes in this patient group.

Methods: A total of 2,193 RA patients (ages ≥18 years) starting either methotrexate (MTX) monotherapy or a tumor necrosis factor inhibitor in combination with MTX were retrieved from the Norwegian Disease-Modifying Antirheumatic Drugs Register (NOR-DMARD).
