Description

• Chronic and systemic inflammatory autoimmune disease
• Unknown etiology
• Usually affects diarthrodial joints, synovial membranes
• Affects muscles, joints, and extra-articular structures of the body
• Fibrinoid degeneration of the collagen fibers in mesenchymal
• Arthropathy
• Synovitis
• Polyarthritis

Essentials of Diagnosis2

• Part of a broad spectrum of autoimmune rheumatic disorders
• 2010 ACR-EULAR classification criteria for rheumatoid arthritis: a score of ≥ 6/10 is needed for classification of a patient as having definite RA):
  • Joint involvement
    • 0 = large joint
    • 1 = 2-10 large joints
    • 2 = 1-3 small joints (with or without involvement of large joints)
    • 3 = 4-10 small joints (with or without involvement of large joints)
    • 5 = >10 joints (at least 1 ...
