What this trial studies

This study aims to establish a national registry for Takayasu arteritis (TA) in China to gather real-world data on the disease's characteristics, diagnosis, activity, severity, treatment, and outcomes. By analyzing this information, researchers hope to enhance understanding of the epidemiology and pathophysiology of TA, particularly in the Chinese Han population. The study will also explore the relationship between specific cytokines and HLA gene alleles with TA activity. The ultimate goal is to develop effective monitoring and treatment strategies for patients with TA.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals diagnosed with Takayasu arteritis who are under 40 years of age and exhibit specific clinical symptoms.

Not a fit: Patients with vessel lesions solely due to atherosclerosis or those with giant cell arteritis may not benefit from this study.

Why it matters

Potential benefit: If successful, this registry could lead to improved monitoring and treatment strategies for patients with Takayasu arteritis.

How similar studies have performed: While there have been studies on Takayasu arteritis, this registry approach is relatively novel and aims to fill significant gaps in understanding the disease in the Chinese population.

Eligibility criteria

Inclusion Criteria:

* Age at disease onset \< 40 years. (Development of symptoms or findings related to Takayasu arteritis at age \<40 years)
* Claudication of extremities. (Development and worsening of fatigue and discomfort in muscles of 1 or more extremity while in use, especially the upper extremities)
* Decreased brachial artery pulse. (Decreased pulsation of 1 or both brachial arteries)
* BP difference \>10 mm Hg. (Difference of \>10 mm Hg in systolic blood pressure between arms)
* Bruit audible on auscultation over 1 or both subclavian arteries or abdominal aorta.
* Arteriogram abnormality. (Arteriographic narrowing or occlusion of the entire aorta, its primary branches, or large arteries in the proximal upper or lower extremities, not due to arteriosclerosis, fibromuscular dysplasia, or similar causes; changes usually focal or segmental)

Exclusion Criteria:
