Takayasu’s Arteritis

Takayasu’s Arteritis (TAK) is a chronic, idiopathic, large-vessel vasculitis that primarily targets the aorta and its major primary branches. It is characterized by granulomatous inflammation leading to stenosis, occlusion, aneurysm formation, or dilatation of the affected vessels.

The exact etiology remains unknown. It is considered an autoimmune process triggered by an unidentified antigen in genetically susceptible individuals. There is a strong association with specific HLA alleles (e.g., HLA-B52).

TAK involves T-cell and macrophage-mediated inflammation of the vessel wall. Inflammatory cells infiltrate the vasa vasorum, leading to thickening of the media and adventitia, destruction of elastic fibers, and eventual fibrosis, which results in luminal narrowing or arterial wall weakening.

TAK primarily affects females (ratio 8:1 to 9:1), usually with an onset between ages 10 and

1. Prevalence is highest in Asian populations, though it occurs globally.

Genetic predisposition (HLA-B52), female gender, age under 40, and potential environmental triggers or infections (e.g., Mycobacterium tuberculosis).

A. Early Symptoms: Fatigue, malaise, fever, weight loss, night sweats, arthralgia.
B. Common Symptoms: Claudication of extremities, dizziness, syncope, headaches, visual disturbances.
C. Advanced Symptoms: Hypertension (renal artery involvement), angina, heart failure, stroke, aortic regurgitation.
D. Emergency Symptoms: Sudden loss of vision, acute limb ischemia, aortic dissection, severe hypertension-related crisis.

Asymmetric blood pressure readings, absent or diminished peripheral pulses ("pulselessness"), arterial bruits (carotid, subclavian, abdominal aorta), and disparity in pulse volume.

A. Clinical Assessment: Based on American College of Rheumatology (ACR) criteria.
B. Laboratory Testing: Elevated ESR and CRP.
C. Imaging Studies: MRA, CTA, or PET-CT are gold standards.
D. Functional Tests: Cardiac stress testing.
E. Biopsy Findings: Not typically performed; shows granulomatous arteritis.
F. Genetic Testing: HLA-B52 screening (research/supportive).
G. Differential Diagnosis: Giant cell arteritis, atherosclerosis, fibromuscular dysplasia.

Erythrocyte Sedimentation Rate (ESR)
Type: Blood Test
Purpose: Assess systemic inflammation.
Expected Findings: Elevated levels.
Interpretation: Correlates with disease activity.

Magnetic Resonance Angiography (MRA): Excellent for visualizing vessel wall thickening and luminal changes without ionizing radiation.
Positron Emission Tomography (PET-CT): Detects active metabolic inflammation in vessel walls prior to structural changes.

Giant Cell Arteritis (usually age >50), atherosclerosis (usually localized, risk factors present), fibromuscular dysplasia (bead-like appearance), and infectious aortitis.

Stenosis, aneurysms, aortic regurgitation, stroke, renovascular hypertension, and myocardial infarction.

A. Lifestyle Modifications: Smoking cessation, aerobic exercise (as tolerated).
B. Preventive Measures: Blood pressure monitoring, aspirin for cardiovascular risk.
C. Medical Treatment: Corticosteroids (Prednisone), DMARDs (Methotrexate, Azathioprine), Biologics (Tocilizumab, TNF-inhibitors).
D. Surgical Treatment: Bypass grafting for critical stenosis.
E. Interventional Procedures: Angioplasty or stenting (reserved for stable disease).
F. Rehabilitation: Physical therapy for endurance.
G. Emergency Management: High-dose IV steroids, surgical repair of dissection.

Variable; many achieve remission, but others face progressive vascular damage. Early diagnosis significantly improves survival and reduces severe complications.

No primary prevention exists. Secondary prevention involves rigorous control of inflammation and blood pressure management.
