Rheumatoid Arthritis Treatment Guidelines

Initial Treatment Protocol

• The American College of Rheumatology recommends starting methotrexate at 15 mg/week with folic acid 1 mg/day, with dose escalation to 20-25 mg/week as tolerated within the first 3 months if needed 1, 2
• Lower doses may be required in elderly patients and those with chronic kidney disease, and consider short-term systemic glucocorticoids for temporary symptom relief 1, 3, 2

Initial Diagnostic Investigations

• Perform clinical examination to detect synovitis, which may be confirmed by ultrasonography if needed, and assess risk factors for persistent/erosive disease including number of swollen and tender joints, elevated inflammatory markers, presence of rheumatoid factor and anti-CCP antibodies, and radiographic erosions 2

Treatment Escalation

• For patients with moderate disease activity after 3-6 months on optimized MTX, add sulfasalazine and hydroxychloroquine for triple DMARD therapy, or consider switching to subcutaneous MTX if oral administration is ineffective 4, 2
• For patients with high disease activity at 3 months despite optimized MTX, add a biologic agent, such as a TNF inhibitor or abatacept 4, 2

Monitoring and Adjustment

• Assess disease activity every 1-3 months until treatment target is reached, using composite measures like SDAI or CDAI, and adjust therapy accordingly 2
• If low disease activity is achieved, continue current therapy, but if moderate or high disease activity persists, optimize MTX dose or consider adding biologic therapy 1, 3

Non-Pharmacological Interventions

• Incorporate dynamic exercises and occupational therapy, provide patient education about disease management, implement programs for coping with pain and maintaining work ability, and consider cognitive behavioral therapy for patients with fatigue 2, 5
