Study Notes
Large Vessel Vasculitis
- Characterized by compromised vessel lumen, leading to tissue ischemia.
- Includes Giant Cell Arteritis and Takayasu’s Arteritis.
Medium Vessel Arteritis
- Conditions include Polyarteritis Nodosa and Kawasaki’s Disease.
Small Vessel Vasculitis
- Includes various conditions:
- Granulomatosis with Polyangiitis (Wegener’s granulomatosis)
- Eosinophilic Granulomatosis with Polyangiitis (EGPA) (Churg-Strauss syndrome)
- Microscopic Polyangiitis
- Henoch-Schönlein Purpura
- Essential Cryoglobulinemic Vasculitis
- Cutaneous Leukocytoclastic Vasculitis
Major Pathophysiologic Mechanisms
- Immune complex mediated mechanisms involved.
- Conditions related to immune complexes include:
- Henoch-Schönlein Purpura
- Serum Sickness
- Cryoglobulinemia
- Vasculitis associated with chronic viral disease.
ANCA-Associated Vasculitis
- Includes:
- Granulomatosis with Polyangiitis
- Eosinophilic Granulomatosis with Polyangiitis (EGPA)
- Microscopic Polyangiitis
- Associated with antineutrophil cytoplasmic antibodies (ANCA) that target cytoplasmic granule antigens.
Clinical Features of Vasculitis
- Common symptoms include:
- Constitutional symptoms (fatigue, fever)
- Headaches
- Scalp tenderness
- Cranial artery abnormalities
- Visual symptoms
- Claudication and neurologic problems
- Bruit and pulselessness
Takayasu’s Arteritis
- Granulomatous inflammation of large arteries in young women (ages 10-30).
- Female to male ratio of 4:1.
- Clinical symptoms include:
- Upper extremity claudication
- Hypertension
- Pain in carotid arteries
- Visual abnormalities
- Musculoskeletal symptoms
- Bruit, pulselessness, blood pressure discrepancies
- Erythema nodosum
- Cardiac and pulmonary symptoms.
Polyarteritis Nodosa
- Most prevalent in individuals in their 5th-6th decade of life (age group).
- Male to female ratio is 2:1.
- Symptoms include:
- Muscle pain or weakness
- Weight loss
- Mononeuritis multiplex
- Polyneuropathy
- Azotemia and hypertension
- Testicular pain
- Skin ulcers and infarcts
- Livedo reticularis
- Abdominal pain.
- Diagnosis often involves biopsy and angiography.
Kawasaki’s Disease
- Acute febrile illness associated with systemic vasculitis primarily in infants and young children (mean age 1.5 years).
- Male to female ratio of 1.5:1.
- Principal clinical features:
- Fever
- Rash
- Conjunctivitis
- Changes in lips and oral cavity
- Changes in peripheral extremities
- Cervical lymphadenopathy.
Granulomatosis with Polyangiitis (Wegener’s Granulomatosis)
- Prevalence of 0.003%.
- Affects all age groups (mean age 41).
- Male to female ratio is equal.
- Clinical features include involvement of:
- Upper airway
- Lungs
- Kidneys
- Eyes
- Skin
- Musculoskeletal system
- Gastrointestinal, genitourinary, and cardiac systems.
Eosinophilic Granulomatosis with Polyangiitis (EGPA)
- Also known as Churg-Strauss syndrome.
- Key symptoms include:
- Asthma and pulmonary disease
- Nervous system involvement
- Renal disease
- Skin manifestations
- Gastrointestinal, cardiac, and ocular symptoms.
Microscopic Polyangiitis
- Affects small vessels with minimal or no immune deposits.
- Characterized by necrotizing vasculitis.
