Rheumatoid Arthritis Management

Diagnostic Workup

The American College of Rheumatology recommends evaluating for symmetric polyarthritis with joint swelling, especially of the hands and feet, although any appendicular joint may be involved 1, 3
Document morning stiffness lasting 1 hour or longer, as this is a characteristic symptom of rheumatoid arthritis 3
Look for characteristic subcutaneous nodules and extra-articular manifestations (interstitial lung disease, vasculitis, inflammatory eye disease) which indicate severe disease 3, 4
Anti-citrullinated protein antibody (ACPA) has high specificity (90%) and moderate sensitivity (60%) for RA, while Rheumatoid factor (RF) has lower specificity (70%) with comparable sensitivity to ACPA 1
Inflammatory markers such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) can be used to assess disease activity 1

The European League Against Rheumatism recommends initiating early treatment to prevent joint damage and disability, with the goal of achieving remission or low disease activity within 3-6 months of treatment initiation 1, 2, 5
Use a treat-to-target approach with regular monitoring and treatment adjustment, targeting remission or low disease activity 2, 5, 6
Methotrexate (MTX) is the first-line DMARD for newly diagnosed RA, and should be started at an appropriate dose and optimized before considering inadequate response 7
Consider adding hydroxychloroquine and sulfasalazine (triple therapy) if MTX monotherapy is insufficient 8
If disease activity remains moderate to high despite optimized MTX, add a biologic agent (TNF inhibitor, abatacept, tocilizumab) or targeted synthetic DMARD (JAK inhibitor) 9, 5

Use composite measures (SDAI, CDAI) to determine disease activity, with remission defined as SDAI ≤3.3 or CDAI ≤2.8, and low disease activity defined as SDAI ≤11 or CDAI ≤10 3, 7, 9
Monitor every 1-3 months during active disease, and adjust therapy if target is not reached within 3-6 months 2, 1

Patient education about disease pathophysiology and self-management is crucial for effective disease management 7
Occupational therapy for joint protection techniques and assistive devices, dynamic exercise programs incorporating aerobic exercise and resistance training, and adequate rest during periods of active inflammation can help improve functional outcomes 7
Cognitive behavioral therapy for fatigue management can also be beneficial 7

Smoking cessation is critical as tobacco use predicts worse outcomes in patients with rheumatoid arthritis 7
Multidisciplinary care involving a rheumatologist, primary care physician, and allied health professionals is essential for optimal disease management 7
