Active clinical trials for "Takayasu Arteritis"

A cross-sectional study design and online questionnaire was used to assess the informational needs of patients with several different types of systemic vasculitis. Patients were recruited from within the Vasculitis Clinical Research Consortium (VCRC) online Patient Contact Registry1. Survey responses from participants in the VCRC Patient Contact Registry were compared to responses from a similar survey recently administered to patients within a United Kingdom (UK) based vasculitis support group (Vasculitis UK).

The purpose of this study is to provide validation of patient-reported data in the VCRC Patient Contact Registry by comparing patient-reported data with data provided by the physician who is the primary provider caring for the patient's vasculitis. Patients enrolled in the Patient Contact Registry with Behcet's disease, eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (EGPA), giant cell arteritis (GCA), granulomatosis with polyangiitis (Wegener's) (GPA), microscopic polyangiitis (MPA), polyarteritis nodosa (PAN), and Takayasu's arteritis (TAK) were invited via email to participate in this study.

The purpose of this study is to learn about the impact of vasculitis on employment and income in patients with different systemic vasculitides. All patients enrolled in the Vasculitis Clinical Research Consortium (VCRC) Patient Contact Registry, living in USA or Canada, and followed for more than 1 year since the vasculitis diagnosis will be invited via email to participate in this study, based on an online survey.

The purpose of this study is to learn about how patients with vasculitis think about their illness and to assess to what extent patient perceptions of illness are associated with physical, mental, and social functioning

Takayasu Arteritis (TA) affects medium and large caliber arteries causing stenosis, occlusion or aneurysms. It has great predilection for the aortic arch, subclavian and extracranial arteries. The global prevalence is of 1 to 2% per million inhabitants, which varies by geographical region. The main cause of death in TA is of cardiovascular origin and includes ischemic cardiomyopathy and valvular disease. The aim of this study was to evaluate the surgical experience according to the type of surgery in subjects with TA with and without inflammatory activity. Methods: This was a retrospective, descriptive, cross-sectional study run between 1977 and 2017. Patients with Takayasu arteritis with more than 3 classification criteria according to the American College of Rheumatology (ACR) were included. The surgeries were classified as: Organ preservation, cardiac, bypass, exclusion and replacement. Inflammatory activity was evaluated.

This study seeks to understand the journey that patients eventually are diagnosed with vasculitis experience in the period prior to their formal diagnosis by a healthcare provider. Data elements of interest include average time from the onset of the first symptoms to the time a diagnosis of vasculitis is confirmed. Other aims include identifying factors associated with the time to diagnosis. These factors will be divided into: a) intrinsic factors, or so-called "patient-related factors", such as the type of vasculitis symptoms, patient demographics, socioeconomic status, patients' beliefs regarding the etiology of their symptoms, and other factors, and b) extrinsic factors, or "professional/health system factors", such as healthcare access, referral patterns, testing patterns, and other factors. Understanding such factors can guide future efforts to shorten delays in diagnosis and thereby improve outcomes. All analyses will be done for the population of patients with vasculitis as a whole and by individual types of vasculitis.

The purpose of this study is to demonstrate that [18F]FDG PET is a a better method than clinical and laboratory values for the identification and assessment of inflammatory activity in patients with Takayasu Arteritis (TA), allowing long-term follow-up with a precise evaluation of response to therapy.

The purpose of this study is to evaluate the ability of contrast enhanced carotid ultrasound to serve as an indicator of disease activity in patients with Takayasu's arteritis or Giant Cell arteritis and to determine if patients with active arteritis have a thickening of their blood vessel walls compared to healthy people of the same age and gender.

Takayasu's arteritis is a rare disorder that causes swelling and damage to the large arteries in the body, such as the aorta. In order to ensure proper treatment, measuring disease activity is critical. The purpose of this study is to establish new biological markers (biomarkers) to assess the severity of disease in people with Takayasu's arteritis.

The purpose of this study is to learn about reproductive health, including fertility and pregnancies, in people with vasculitis.
