Overview
Rheumatoid arteritis, also known as giant cell arteritis (GCA), is a systemic inflammatory vasculitis primarily affecting large- and medium-sized arteries, particularly the extracranial branches of the carotid artery. It commonly presents with headache, jaw claudication, and visual disturbances, requiring prompt diagnosis and treatment to prevent irreversible complications such as stroke and blindness 2.Diagnosis
Clinical Criteria: Headache, new-onset jaw claudication, visual symptoms (e.g., transient vision loss) 2.
Laboratory Tests: Elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels 2.
Imaging: Temporal artery biopsy remains the gold standard for definitive diagnosis 2.
Imaging Alternatives: Ultrasound of temporal arteries can be useful in identifying inflammatory changes 2.Management
First-Line Treatment: High-dose corticosteroids (e.g., prednisone, typically starting at 40-60 mg/day) 2.
Adjunctive Therapy: Addition of low-dose aspirin for cardiovascular protection in selected patients 2.
Tapering: Gradual tapering of corticosteroids under close monitoring to minimize relapse 2.
Second-Line Agents: Consider methotrexate or other immunosuppressive agents for refractory cases or to facilitate corticosteroid tapering 2.Special Populations
Pregnancy: Limited data; management focuses on balancing maternal safety with disease control, often requiring close monitoring and individualized treatment plans 2.
Elderly: Higher vigilance for complications due to increased comorbidities; management similar to general population but with careful consideration of polypharmacy and frailty 2.Key Recommendations
Initiate high-dose corticosteroids promptly upon diagnosis to prevent irreversible complications (Evidence: Strong 2).
Use ESR and CRP levels to monitor disease activity and guide treatment adjustments (Evidence: Moderate 2).
Consider temporal artery biopsy for definitive diagnosis, especially in atypical presentations (Evidence: Strong 2).References
