Active clinical trials for "Vasculitis"

Longitudinal prospective multicenter Armenian registry of systemic autoimmune, autoinflammatory diseases with constitution of bio-banking.

To date, there are no reliable diagnostic blood markers of adult vasculitis. To date, the diagnosis of vasculitis is based on invasive procedure, biopsy of affected tissues potentially at risk of complication . In addition, there are no reliable biomarkers to predict the evolution of vasculitis (relapse, refractory form ...) necessary for the management of patients (type of treatment, duration ..) Prospective study, monocentric (CHU de Tours), non-interventional, aimed at finding diagnostic and prognostic biomarkers (both metabolomic and immunologic) in adult vasculitis patients.

The incidence in pediatrics is very low (about 0.5 per million according to a French study) and therefore the data on the pathology very poor, especially on the therapeutic level. Without appropriate treatment, the mortality rate of the pathology is very high. Existing treatments are almost exclusively composed of immunomodulatory and/or immunosuppressive treatments. Complications related to pathology and iatrogeny are among the first causes of mortality from this pathology and deserve to be studied in order to be known and if possible avoided. The purpose of the study is to achieve a national comparison of clinical and therapeutic practices.

This study will assess the effect of a mindfulness meditation program administered via a smartphone application on health-related quality of life for patients with rheumatic disease.

The purpose of this study it to determine whether the use of a gonadotropin releasing hormone (GnRH)-agonist (depot-leuprolide acetate) during cyclophosphamide (CYC) therapy in women with rheumatic diseases will provide greater ovarian protection than placebo.

The aim of IMPROVE is to define the optimal maintenance therapy for ANCA-associated vasculitides (AASV) by comparing the AZA (standard regimen) with MMF in terms of efficacy, i.e. in preventing relapses. HYPOTHESIS : MMF might be more effective than azathioprine as maintenance drug in AASV patients, reducing by 50% relapse rate, with a same frequency of adverse effects

The systemic vasculitis is a wide-ranging group of diseases that are characterized by the presence of blood vessel inflammation (1). Despite this common feature, each type of vasculitis has a unique variety of clinical manifestations that influences its degree of disease severity and ultimately its management. Immunosuppressive therapy forms the foundation of treatment for almost all forms of systemic vasculitis. The systemic necrotizing vasculitis (SNV) are a subset of vasculitis with significant morbidity and mortality (2). The SNV are Wegener's granulomatosis, allergic angiitis and granulomatosis (AAG) (also known as Churg-Strauss syndrome), polyarteritis nodosum (PAN), microscopic polyangiitis (MPA), and overlap syndrome. In spite of modern therapeutic immune suppressive agents, there remains a not inconsequential morbidity and mortality associated with SNV. The current standard therapy for SNV is chronic oral cyclophosphamide (1-3 mg/kg/day) and corticosteroids (3-6). Transplant doses of cyclophosphamide at 200 mg/kg infused over 4 days is the most common worldwide transplant regimen for systemic lupus erythematosus (SLE) (7). Like SLE, SNV are cyclophosphamide responsive disease. We, therefore, propose a trial of high dose cyclophosphamide with anti-thymocyte globulin (ATG) for patients with SNV.

Treatment of patients with PR3-ANCA-associated vasculitis consists of two phases: remission induction with highly effective, but also relatively toxic, drugs and, secondly, after remission is achieved, maintenance therapy with less toxic drugs. Currently, remission-maintenance therapy with azathioprine is stopped after approximately 18 months. However, the optimal duration of azathioprine maintenance therapy is unknown. The investigators have found that patients with PR3-ANCA-associated vasculitis who remain cytoplasmic anti-neutrophil cytoplasmic autoantibody (C-ANCA) positive after induction of remission have an increased risk to experience relapse of disease. Therefore they will test whether relapse risk in these patients can be reduced by extending maintenance therapy at the cost of acceptable therapy related toxicity. After induction of stable remission, ANCA will be measured by immunofluorescence (IIF). C-ANCA positive patients will be randomized for either standard therapy with azathioprine (until 18 months after diagnosis), or longterm azathioprine maintenance therapy (until 48 months after diagnosis).

The purpose of this study is to test whether additional therapy with plasma exchange improves the chances of kidney recovery in severe kidney vasculitis.

People with rheumatic disease often have decreased strength, muscle mass, and bone mineral density due to repeated bouts of inflammation, normal effects of aging, disuse, and inactivity. The medications used to quell the disease process, such as prednisone, can also have detrimental effects on body composition, strength, and functional capacity. The investigators propose to investigate the feasibility, safety, and effects of resistance exercise in older patients with rheumatoid arthritis (RA) and vasculitis. The unique resistance protocol the investigators propose involves performing movements in a slow and controlled fashion (i.e., no acceleration or use of momentum in the lifting and lowering of the resistance) to minimize force on the joints and connective tissues. This will be conducted in an individually-supervised environment with a new generation of exercise equipment that will accommodate their musculoskeletal capabilities and allow for reproducibility of the exercise protocol. The investigators intend to investigate the feasibility, safety, musculoskeletal, and psychological effects of this resistance exercise protocol in older patients with rheumatoid arthritis and vasculitis by testing their strength, body composition, functional ability, mood, and quality of life before and after this 16-week resistance exercise intervention.
