Filter by:The goal of this multicentre observational study is to compare the safety and effectiveness of rituximab biosimilars to the originator in Canadian patients with Granulomatosis with Polyangiitis (GPA) and Microscopic Polyangiitis (MPA), two main forms of ANCA-associated vasculitis (AAV). The main questions it aims to answer are: - Is there a difference in vasculitis control between originator and biosimilar rituximab? - Is there a difference in adverse effects between originator and biosimilar rituximab? - In the Canadian healthcare context, are wait times to receive approval (financial coverage) for rituximab shorter for biosimilars compared to originators? Investigators will perform study assessments (including recording disease activity, damage, and adverse events) at the time of participants' usual clinical care visits, at regular intervals for 2 years after starting rituximab (for induction or maintenance treatment) or switching from an originator to a biosimilar as part of their usual care. Researchers will compare outcomes among participants who have received rituximab originators (from 2018 onwards) or biosimilars as part of their usual care, to see if there are differences in relapses, remission rates, damage, serious infections, serious adverse events, and treatment approval wait times.
ANCA-associated vasculitis is an autoimmune disease that causes damage to blood vessels. This leads to organ damage with the number of organs affected and the severity of damage varying significantly between patients. Vasculitis patients also have a very high risk of heart attacks and strokes, called cardiovascular disease. A chemical called 'endothelin', produced by the blood vessels, causes vessels to stiffen and raises blood pressure and this associates with cardiovascular risk. The investigators have previously shown that by blocking the effects of endothelin you reduce vessel stiffness, lower blood pressure and improve vessel function. However, these studies only blocked endothelin for a few hours. Now, the investigators would like to see if it is possible to maintain these benefits by blocking endothelin for longer. Sparsentan is a tablet that blocks endothelin and lowers blood pressure. The investigators plan to give sparsentan to patients with vasculitis for 6 weeks. To determine if any beneficial effects of sparsentan are due to blood pressure lowering the investigators will give another group of vasculitis patients a tablet called irbesartan which lowers blood pressure but does not block endothelin. The investigators will compare the results between the two groups.
The main objective is to identify specific risk factors for ANCA vasculitis of occupational and/or environmental origin (exposures identified by questioning, geographical distribution of cases) from the RNV3P data. The secondary objectives are as follows: - Description of cases of ANCA vasculitis seen in French occupational pathology consultation centres: - reasons for consultation, - occupational and environmental etiologies described - occupational situations responsible - aptitude notices - recognition as an occupational disease - Identification of specific risk factors for ANCA vasculitis of occupational and/or environmental origin (exposures identified on questioning, geographical distribution of cases). - For occupational and non-occupational cases of ANCA vasculitis: identification of difficulties encountered by patients at work and proposed work adaptations. - Estimation of the number of applications for recognition of disabled worker status made within this patient group. - Identification of clinical severity and autoimmune profiles of ANCA vasculitis of occupational and/or environmental origin.
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.
The purpose of this study is to evaluate the efficacy and safety of obinutuzumab for the treatment of proteinase 3 Anti-Neutrophil Cytoplasmic Antibody (ANCA)-Associated Vasculitis (PR3-AAV).
As rare disease, vasculitis affects a small number of patients, the cohorts available in the literature are few and the pathophysiological mechanisms remain to be elucidated. The collection of standardized data within a patientheque as part of a multi-year follow-up will facilitate the study of the characteristics of these diseases. This may, in particular, address the main objective of identifying predictors of relapse, as well as secondary objectives for predictive factors of mortality, infectious, cardiovascular or neoplastic complications that affect the prognosis of vasculitis in order to establish a more appropriate management of the patients concerned.
This study aimed to explore the incidence of Anti-neutrophil cytoplasmic antibody (ANCA）-associated vasculitis (AAV) progression and its association with adverse consequences. It will enroll approximately 500 AAV patients in Hunan province of China and follow-up for at least 5 years. Demographic characteristics, clinical and laboratory data will be collected at baseline and every follow-up. The principal clinical outcomes of the study consist of end stage renal disease (ESRD) and death.
The aim of the trial is to study the efficacy and safety of treatment with BDB-001 Injection substitution of glucocorticoid in patients with ANCA-associated vasculitis.
The goal of this study is to evaluate the efficacy and safety of tofacitinib 5 mg twice daily in AAV patients.
1. Include qualified 50 ANCA-associated vasculitis(AAV) patients; and the first 27 patients will be divided into 3 groups with different diffused tension image (DTI) parameters and to choose the best strategy； 2. On baseline, 6 months after treatment and 24 months after treatment, the AAV patients will accomplish the Birming-ham vasculitis activity score(BVAS) besides DTI； 3. The new serum biomarkers of AAV associated peripheral neuropathy will be measured by ELISA； (4) Another cohort with 50 patients with AAV associated peripheral neuropathy who were evaluated by traditional methods (electromyogram) and compared to the patients cohort that evaluated using DTI by cost-benefit analysis
