From the Guidelines
Treatment for Takayasu arteritis should involve a combination of high-dose glucocorticoids and immunosuppressive agents, with the goal of minimizing glucocorticoid-related toxicity and preventing disease progression. The most recent and highest quality study, published in 2021 by the American College of Rheumatology/Vasculitis Foundation 1, recommends initiating treatment with high-dose oral glucocorticoids (GCs) and a non-GC immunosuppressive agent, such as methotrexate (MTX) or azathioprine (AZA), for patients with active Takayasu arteritis.
Key Recommendations
- High-dose glucocorticoids (40-60 mg/day) should be initiated immediately for induction of remission in active Takayasu arteritis 1.
- Non-biological glucocorticoid-sparing agents, such as MTX or AZA, should be given in combination with glucocorticoids in all patients with Takayasu arteritis 1.
- Biological agents, such as tocilizumab or tumor necrosis factor inhibitors, may be used in refractory or relapsing patients 1.
- Regular monitoring of disease activity through clinical assessment, inflammatory markers (ESR, CRP), and vascular imaging is essential 1.
- Surgical interventions, such as angioplasty, stenting, or bypass grafting, may be required for severe vascular stenosis or occlusion causing ischemic symptoms 1.
Treatment Approach
The treatment approach for Takayasu arteritis should be individualized, taking into account the severity of disease, presence of comorbidities, and patient preferences. The goal of treatment is to induce and maintain remission, prevent disease progression, and minimize glucocorticoid-related toxicity.
Monitoring and Follow-up
Regular monitoring of disease activity and adjustment of treatment as needed is crucial to prevent complications and improve outcomes. This includes regular clinical assessments, laboratory tests (e.g., ESR, CRP), and vascular imaging studies (e.g., MRI, CT angiography) 1.

From the Research
Treatment Options for Takayasu Arthritis
- Immunosuppressive agents, including methotrexate, mycophenolate mofetil, and azathioprine, can be used in combination with corticosteroids to bring Takayasu arteritis into remission in many patients 2.
- Anti-tumor necrosis factor-alpha agents have shown promising results in patients with refractory disease 2.
- For patients who require revascularization intervention, both surgical and endovascular procedures can be performed with low morbidity and mortality 2.
- Conventional bypass grafts have been shown to achieve the best long-term outcomes, while percutaneous transluminal angioplasty provides good results for short lesions 2.
Comparison of Immunosuppressive Agents
- A study comparing methotrexate and azathioprine as first-line steroid-sparing immunosuppressive agents found similar remission, relapse, and radiographic progression rates between the two groups 3.
- However, the rate of vascular surgery was significantly higher in the azathioprine group, while the frequency of patients receiving ≤5 mg/day glucocorticoids at the end of follow-up was significantly higher in the methotrexate group 3.
Diagnostic Tests and Treatment Benefits
- A systematic review and meta-analysis found that commonly available diagnostic tests for Takayasu arteritis have varying degrees of accuracy, and that treatment options including glucocorticoids, non-GC nonbiologic therapies, and biologics have different benefits and harms 4.
- Tocilizumab has been shown to improve clinical and laboratory parameters of disease activity in a patient with refractory Takayasu's arteritis, but vascular disease may progress despite treatment 5.
Updates in Diagnosis and Management
- Recent updates in the diagnosis and management of Takayasu's arteritis highlight the importance of early diagnosis and treatment to prevent serious end-organ damage 6.
- Methotrexate, azathioprine, and tumor necrosis factor (TNF) inhibitors have been shown to be effective in treating Takayasu's arteritis, and the 2021 ACR guidelines provide recommendations for diagnosis and management 6.
