Rheumatoid Arthritis: Systemic Damage Beyond the Joints

Rheumatoid arthritis (RA) is a chronic autoimmune disease primarily targeting synovial joints, but its inflammatory cascade can damage multiple organ systems.

Major Manifestations

• Joint destruction: Synovitis → cartilage/bone erosion → deformities (boutonnière, swan-neck, ulnar deviation).
• Bone loss: Periarticular and systemic osteoporosis → fracture risk.
• Tendon/ligament rupture: Inflammation weakens supports → instability.
• Carpal tunnel syndrome: Wrist synovitis compresses median nerve.
• Lung disease: Interstitial lung disease, pleural effusions.
• Cardiovascular disease: Accelerated atherosclerosis → MI, stroke, PAD.
• Anemia of chronic disease.
• Rheumatoid nodules: Subcutaneous, often at pressure points.
• Eye involvement: Scleritis, keratitis, dry eye.

Management Impact

Early, aggressive treat-to-target therapy with DMARDs/biologics slows structural damage, reduces extra-articular complications, and improves longevity. Regular monitoring is essential.
