Rheumatology Vasculitis Revision Notes
Here are your complete MBBS Revision Notes: Rheumatology — Vasculitis as a visual topper-style image! Here's what's covered:

What's Inside the Notes:

1. Definition

Vasculitis = inflammation + necrosis of vessel walls → ischemia/organ damage (primary vs secondary)

2. Classification — 2012 Chapel Hill Consensus

Organized by vessel size: Large → Medium → Small (ANCA-associated & Immune Complex) → Variable vessel

3. Pathogenesis (All Types)

  • ANCA mechanism: Infection → TNF → neutrophil priming → ANCA activates MPO/PR3 → O₂ radicals + proteases → endothelial necrosis
  • Immune Complex: Ag-Ab deposit → complement → neutrophil infiltration
  • Granulomatous: T-cell mediated → giant cell granuloma

4. Location Table

Each disease mapped to vessel type + exact organs (e.g., PAN = NO lungs, NO ANCA; GPA = upper airway + lungs + kidneys)

5. Diagnosis

ANCA testing, biopsy (gold standard), ESR/CRP, angiography (PAN = beaded), Echo (Kawasaki)

6. Treatment

  • GCA/Takayasu → Prednisolone + Tocilizumab
  • GPA/MPA/EGPA → Rituximab or Cyclophosphamide + steroids
  • Kawasaki → IVIG + Aspirin
  • IgA vasculitis → usually self-limiting

Exam Tips & Mnemonics

  • ★ PAN = NO lung, NO ANCA, NO glomerulonephritis
  • ★ GCA age >50 | Takayasu age <40 | Kawasaki age <5
  • ★ c-ANCA (PR3) = GPA; p-ANCA (MPO) = MPA/EGPA
