The Registry Study of Takayasu Arteritis in East China

This registry study tracks patients with Takayasu Arteritis in East China. Takayasu Arteritis is a rare inflammatory disease that affects the large arteries — especially the aorta and its major branches. The inflammation causes the arteries to narrow or become blocked, reducing blood flow to vital organs and limbs. It primarily affects young women and can cause symptoms like arm weakness, blood pressure differences between arms, and arterial bruits (whooshing sounds a doctor can hear with a stethoscope). The registry collects long-term data on diagnosis, treatment, and outcomes to improve understanding and management of this rare disease in the East Asian population, where it is more prevalent than in Western countries. Patients must meet at least 3 of 6 defined clinical criteria for diagnosis and sign informed consent. You may be eligible if: - You have been diagnosed with Takayasu Arteritis (meeting at least 3 of 6 clinical criteria) - You are between 18 and 65 years old (with onset at or before age 40) - You are located in East China - You are willing to sign informed consent You may NOT be eligible if: - You have another autoimmune disease (lupus, ANCA vasculitis, Behcet's, etc.) - You have serious uncontrolled organ disease unrelated to Takayasu - You have active tuberculosis or are at high risk for TB - You have a malignant tumor - You have had an organ transplant or are planning one Talk to your doctor to see if this trial is right for you.
