    • Lupus Systemic Lupus Erythematosus (SLE)

    • Chronic inflammatory auto-immune disorder
    • Can affect almost all organ systems (systemic),especially:
      • Skin 
      • Joints
      • Blood
      • Kidneys
    • Variable presentations, course, and prognosis 
    • Characterized by remissions and flares
    • Mild, serious, life-threatening, or death

    Historical Context

    • “Lupus erythematosus” named for the characteristic skin rash
    • Malar “Butterfly” Rash
    • Systemic
    • Autoimmune
    • A “rheumatic disease”
    • Common feature = presence of symptoms or signs of disease in the joints or periarticular tissues

    ACR Criteria for Classification of SLE:

    • 11 criteria
    • SLE suspected in patients with features affecting ≥ 2 organ systems
    • Patients with ≥ 4 or more criteria at any time
      • SLE diagnosis
      • 95% specificity
      • 85% sensitivity
    • Patients with < 4 criteria may still be diagnosed with SLE
