First-line treatments
Disease management and monitoring
Active treatment with regular monitoring by a healthcare provider is recommended.
Glucocorticoid Induction Therapy
High-dose corticosteroids initiate rapid control of aortic inflammation. Gradual taper over 3-6 months based on clinical and radiographic response. Represents the cornerstone of initial disease management.
Rituximab for Refractory Disease
Anti-CD20 monoclonal antibody depletes B cells and reduces IgG4-producing plasma cells. Particularly useful in patients who relapse on steroids or have contraindications to prolonged corticosteroid use.
Additional treatment options
Vascular Imaging Surveillance
Serial CT or MR angiography to monitor aortic wall thickness, aneurysm formation, and response to therapy. Imaging frequency determined by disease severity and treatment response.
monitoringSteroid-Sparing Immunosuppressants
Conventional steroid-sparing agents such as mycophenolate mofetil, azathioprine, or methotrexate help maintain remission while reducing corticosteroid exposure. Used for maintenance therapy.
medicationCardiovascular Risk Reduction
Aggressive blood pressure control, lipid management, and smoking cessation to reduce stress on the affected aorta. Low-impact exercise as tolerated; avoid activities that significantly elevate blood pressure.
