Filter by:Takayasu arteritis (TAK) is a rare chronic inflammatory arteritis, which lacks an effective well-accepted intervention strategy. We classify TAK patients into 3 levels, including mild, moderate, and severe. And the biological agents tocilizumab and adalimumab are randomly prescribed in severe patients, to find out the relatively better treatment strategy, facilitating better intervention strategy in severe TAK patients.
Takayasu arteritis (TAK) is a rare chronic inflammatory arteritis, which lacks an effective well-accepted intervention strategy. Here we tried to classify TAK patients in 3 levels, including mild, moderate, and severe, and prescribe methotrexate and tofacitinib randomly in mild and moderate patients, to observe the relatively better treatment strategy, facilitating better intervention strategy in TAK patients.
AION is the main cause of blindness in patients with GCA. High dose steroid is the reference treatment of this condition, but medical unmet need remains. Subcutaneous tocilizumab, a targeted biotherapy, recently received marketing authorization for the treatment of GCA, but only demonstrated at yet that it can allow steroid dose sparing. The aim of this study is to assess the benefit of tocilizumab and IV steroids combination or IV steroids alone, in the treatment of AION due to GCA.
Imaging the inside of coronary arteries (intravascular imaging) offers great insight into the assessment and treatment of coronary artery disease. Over time, substances such as fat, cholesterol and calcium can build up into 'plaques' in the arteries, causing narrowings or even blockages. These plaques can also rupture, causing cardiovascular events such as heart attacks or strokes. By using ultrasound and infrared technology, intravascular imaging can help assess these plaques, however this is an invasive technique involving angiography. Plaque composition, structure and stability can be affected by inflammation and the stress that the arteries are under. The investigators have pioneered novel minimally-invasive methods for modelling arterial stress using computed tomography coronary angiography (CTCA), as well as imaging coronary arterial inflammation using a positron emission tomography (PET) scan. Before embarking upon a large-scale clinical outcome study to determine whether these novel methods can improve risk prediction, the aim is to perform a proof-of-principle study to further develop our methodology for hybrid image analysis, and to validate this technique against high-resolution intravascular imaging as a surrogate marker of histology.
Longitudinal imaging in patients with large vessel vasculitis to predict further disease course
Evaluation of the structural features of temporal arteritis using two frequencies probes: 18 and 22Mhz.
Cardiovascular Disease (CVD) is a leading cause of death in the developed world. Atherosclerosis causes plaques in the blood vessels and is a common form of CVD. Inflammation is now recognized as a major cause of atherosclerosis. Therapies that target inflammation are being examined as a potential treatment option. Imaging to detect inflammation may be a solution to understand mechanisms and to optimize patient selection and outcomes for these drugs. Fluorodeoxyglucose (FDG) PET imaging can detect inflammation in the plaque and identify patients vulnerable to plaque rupture which cause events such as myocardial infarctions (MI) and strokes. The primary objective of this proposal(CADENCE) is to determine if the drug colchicine has an effect on plaque inflammation in patients at high risk for events (patients with diabetes or pre-diabetes and recent myocardial infarction, stroke or transient ischemic attacks (TIAs)). This mechanistic and proof-of-concept study will set the stage for future studies that will determine if inflammation imaging can be integrated into clinical practice to personalize decisions for anti-inflammation therapies.
The main objective of this study is to evaluate the efficacy of upadacitinib in combination with a corticosteroid taper regimen compared to placebo in combination with a corticosteroid taper regimen.
Giant cell arteritis (GCA) or Horton's disease: frequent large vessel vasculitis (cephalic) (incidence estimated at 9 per 100,000 in France), potentially responsible for blindness. Treatment: corticosteroid therapy, which is effective in the vast majority of cases. Clinical problem: relapse; 36% to 44% of patients have a relapse that occurs in the first year for many patients, requiring a re-escalation of corticosteroid therapy, with its consequences: - Cumulative dose of corticosteroid therapy that causes cardiovascular and infectious morbidity. - Requires additional immunosuppressive treatment.
Takayasu arteritis associated renal artery stenosis (TARAS) is the biggest cause of hypertension in young people <40 years old. Hypertension caused by renal artery stenosis is usually hard to control in spite of two or more anti-hypertension drugs. Percutaneous transluminal angioplasty (PTA) is recommended for hypertension caused by TARAS. In previous clinical practice, we observed relatively effects of PTA on controlling the blood pressure in patients with TARAS. But, high re-stenosis rate was also indicated. Drug coated balloon (DCB)is a new type of PTA, which could improve the re-stenosis rate significantly. In the clinical trials of peripheral vascular disease, it has been confirmed that DCB had lower re-stenosis rate than PTA. However, up to date, no studies was found about the use of DBC in TARAS. Thus, this study was design as a random, double blind trial to evaluated the effects and safety of DCB in the treatment of hypertension caused by TARAS.
