Takayasu arteritis
Background
- Large-vessel vasculitis, leads to fibrosis and narrowing of the vessels [1]
- Most often affects women of Asian descent during reproductive age
- Diagnosis is often delayed due to the rarity of the disease and varied symptoms
- The disease process chronically improves and relapses[2]
Vasculitis Syndrome Types
- Large vessel
- Takayasu arteritis
- Giant cell arteritis (temporal arteritis)
- Medium-vessel
- Kawasaki disease
- Polyarteritis nodosa
- Thromboangiitis obliterans (Buerger's disease)
- Primary angiitis of the central nervous system
- Small-vessel
- Henoch-Schönlein purpura
- ANCA-associated vasculitides
- Granulomatosis with polyangiitis (Wegner's)
- Eosinophilic granulomatosis with polyangiitis (Churg-Strauss)
- Microscopic polyangiitis
- Cutaneous leukocytoclastic angiitis (“hypersensitivity vasculitis”)
- Essential cryoglobulinemia, cryoglobulinemic vasculitis due to hepatitis C
- Behçet's disease]
- Secondary vasculitides and other/miscellaneous
- Drug-induced vasculitis
- Serum sickness
- Vasculitis associated with other rheumatic diseases (e.g. SLE)
Clinical Features
- Hypertension
- Congestive Heart Failure
- CVA
- Dizziness
- Pulselessness
- Claudication
- Bruits
- Visual disturbances
- Arthralgias/Myalgias
- Aortic Regurgitation
- Weight Loss
- Arterial Aneurysm
Differential Diagnosis
Evaluation
- Work up should be tailored to the patient's symptoms as this disease process affects multiple organ systems due to vascular damage
Laboratory
- ESR, CRP, WBC may or may not be elevated
- Anemia may be present
Imaging
- Angiography revealing narrowing/occlusion of large vessels (e.g. Aorta) is the gold standard [3]
- MRA or CTA can be used as well to appreciate vascular stenoses
Management
- Oral Prednisone 1 mg/kg for the first month followed by a taper
- Taper to approximately 10 mg/day
- The addition of Methotrexate or Mycophenolate mofetil to Prednisone therapy may be more effective than monotherapy
- Additional processes (e.g. Hypertension or Congestive Heart Failure) will require disease specific treatments
- In advanced disease processes, Cardiac or Vascular Surgery or Interventional Radiology may be required for angioplasty, stenting, or valvular repair
Disposition
- Disposition dependent on presentation and disease severity
- Admit patients with severe aortic regurgitation, large aortic aneurysm, or other concerning features
