View clinical trials related to Takayasu Arteritis.
Filter by:Takayasu's arteritis(TAK) is a rare systemic vasculitis which can cause ischemia or inflammation of the involved organs and increase the overall mortality rate.The traditional treatment of TAK is primarily empirical. The most commonly used drugs for treating active TAK are glucocorticosteroids(GC) and immunosuppressants. However, the genital toxicity of CYC has limited its long term use. In a pilot study carried out by the principal investigator of this study has shown that mycophenolate mofetil(MMF) combined with MTX is effective and with few adverse effects. The purpose of this prospective open-label study is to compare the efficacy and safety of GC+MMF+MTX with GC+CYC followed by GC+AZA for the treatment of active TAK. 150 patients with active TAK will be recruited and randomized in a 2:1 ratio to GC+MMF+MTX group and C+CYC and AZA group. Patients were followed for 52 weeks for efficacy and safety assessment.
The purpose of this study is to investigate the efficacy and Safety of Leflunomide in Patients With Active Phase of Takayasu's Arteritis
The purpose of this study is to collect existing tissue specimens from subjects enrolled in Vasculitis Clinical Research Consortium (VCRC) studies. Analysis of these tissue specimens and linked clinical data collected through VCRC studies may lead to the identification and development of a series of translational research projects. Results of these studies will provide vasculitis researchers with insight into the causes of these diseases and generate new ideas for diagnostic tests and therapies, and will be of great interest to the larger communities of researchers investigating vasculitis and other autoimmune, inflammatory, and vascular diseases.
Takayasu arteritis (TA) is a chronic large-vessel vasculitis that mainly affects the aorta and its major branches. The epidemiology and pathophysiology of TA is still unclear in China, although many studies have been done. Our previous study supporting by National Natural Science Foundation of China indicated the cytokines such as hs-CRP, NT-proBNP and tumor necrosis factor-alpha (TNF-α) can be used to monitor TA activity, and HLA gene alleles were associated with TA in Chinese han population. Further investigations with larger samples are needed to fully understand the a pathophysiology of TA. The purpose of this study is to build a Chinese national registry system for TA to obtain real-world information, such as current status of characteristics, diagnosis, disease activity, the severity of disease, treatment and outcomes of Chinese TA patients. To analysis and development of effective disease monitoring and treatment strategies.
This pilot trial studies how well fluorine F 18 clofarabine positron emission tomography (PET)/computed tomography (CT) works in imaging patients with autoimmune or inflammatory diseases. Fluorine F 18 clofarabine is an imaging agent or tracer which may be taken up by inflammatory tissue in the body. Diagnostic imaging, such as PET/CT scans, can be used to measure the amount of injected tracer that is taken up by inflammatory tissue. PET/CT scan may help to determine how fluorine F 18 clofarabine is distributed throughout the body.
The purpose of this study is to learn about the experience of women with vasculitis who become pregnant. In particular, the study will consist of several online surveys to assess 1. each woman's vasculitis severity and pregnancy-related experiences, and 2. pregnancy outcomes.
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.
Clinical study of anti-tumor necrosis factor therapy in patients with Takayasu arteritis. This study is single arm (anti Tumor necrosis factor therapy only) clinical trial. Enrolled patients will be 11
Background: - Vasculitis is a group of diseases that inflame and damage blood vessels and tissue. It can cause many medical problems. Few tests can diagnose the disease, and none can reliably predict a relapse. Researchers want to study people s genes and follow people over time to see how the disease affects them. Objective: - To learn the signs, symptoms, imaging tests, genetic markers, and blood tests that can help identify people with vasculitis and predict what will happen to them over time. Eligibility: - People age 3 and older who have or are thought to have vasculitis, or are related to someone with it. - Healthy volunteers. Design: - Participants will be evaluated by a doctor who has expertise caring for patients with vasculitis. - Participants will give a blood sample. Some will give a urine sample. - Some participants may have brushings or biopsies taken from the inside lining of the nose. - Images of participants blood vessels may be taken using scans. For some scans, participants will lie on a table that moves in and out of a cylinder that takes pictures. For some scans, a contrast agent may be injected into an arm vein. Other scans may use a radioactive form of sugar. Healthy minors will not have scans. - Some participants will answer questionnaires. - Some participants will have their tests done at NIH. Others will have their doctor take the blood, saliva, or cheek swab samples and send them to NIH. - Some participants will have one visit lasting 1-2 (but sometimes up to 4) days. Some participants may have follow-up visits every 3 - 6 months, indefinitely.
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.
