Filter by: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 reproductive health, including fertility and pregnancies, in people with vasculitis.
Multi-center, randomized, double-blind, placebo-controlled trial to evaluate the efficacy of abatacept to achieve sustained glucocorticoid-free remission in patients with relapsing non-severe granulomatosis with polyangiitis (Wegener's) (GPA) . Participants will be randomized 1:1 to receive either abatacept 125 mg or placebo administered by subcutaneous injection once a week. Participants will continue on study treatment for a minimum of 12 months unless they experience a disease relapse or disease flare. Participants who experience a non-severe disease relapse, non-severe disease worsening, or who have not achieved remission by month 6 will have the option of entering an open-label trial period whereby they would receive open-label abatacept.
TRANSREG will assess the safety and biological efficacy of low-dose IL2 as a Treg inducer in a set of 14 autoimmune and auto-inflammatory diseases, with the aim to select diseases in which further therapeutic development will be performed. Extensive biological- and immune-monitoring pre- and post-IL2 will contribute (i) to define the common or distinct processes responsible for the breakdown of immunological tolerance in these pathologies and (ii) to discover potential biomarkers of the IL2 response.
The purpose of this study is to test whether additional therapy with plasma exchange improves the chances of kidney recovery in severe kidney vasculitis.
The investigators recently showed an abnormal expansion of NK-like CD4+ T cells in Wegener's granulomatosis (WG), mainly in the diffuse vasculitis presentation. These cells expressed an assortment of activating NK cell receptors and their signaling partners, in particular DAP12. The investigators hypothesize that DAP12, or a downstream signaling target of DAP12, is the missing link between the different cell components involved in WG (neutrophils, macrophages, CD4 T cells).
Vasculitis is group of diseases where inflammation of blood vessels is the common feature. Patients typically present with fever, fatigue, weakness and muscle and joint aches. These symptoms are very common among many different diseases, not just vasculitis. A clustering of other symptoms, physical examination findings, blood tests, radiology and biopsy help make the diagnosis. There are currently no criteria to help doctors make a diagnosis of vasculitis when a patient presents with these non specific symptoms and they are reliant on previous experience and disease definitions. One of the aims of this project is to develop diagnostic criteria for the primary systemic vasculitides (granulomatosis with polyangiitis (Wegener's), microscopic polyangiitis, Churg Strauss syndrome, polyarteritis nodosa, giant cell arteritis, Takayasu arteritis). We, the investigators, will do this by studying a large group of patients with vasculitis and comparing them to a large group of patients that present in a similar way, but do not have vasculitis. By comparing the 2 groups we will create a list of items to differentiate between vasculitis and 'vasculitis mimics'. We also aim to update the current classification criteria. Classification criteria are used to group patients into different types of vasculitis, once a diagnosis of vasculitis has been made, and are useful for studying patients in clinical trials with similar or identical diseases. The current classification criteria (American college of Rheumatology 1990 criteria) were developed 20 years ago, before the availability of some important diagnostic tests (e.g. antineutrophil cytoplasmic antibodies [ANCA]), and are now not consistent with some of the current disease definitions. Therefore to progress future research in vasculitis, it is important that the classification criteria are updated. We will recruit 260 patients with each of the 6 types of vasculitis and compare them with 1300 controls (patients with the 5 other types of vasculitis), in order to determine the optimal combination of symptoms, signs and investigations that classify each person into the appropriate group.
The purpose of this study is to determine whether Infliximab (monoclonal anti-tumour necrosis factor alpha antibodies) are safe and effective in the treatment of anti-neutrophil cytoplasm antibody (ANCA) associated vasculitis.
The Systemic Necrotizing Vasculitides (SNV) encompass a group of rare diseases which include Wegener's Granulomatosis (WG), Churg-Strauss Syndrome (CSS), Microscopic polyangiitis (MPA)and Polyarteritis nodosa (PAN). Common histological findings are inflammation with fibrinoid necrosis of the small vessels and sporadic or absent immune-deposits. The gold standard therapy for SNV is currently represented by the association of Cyclophosphamide and Prednisone. The limits of this approach are the high frequency of recurrent disease and an increased incidence of malignancy and infections. The aim of the present study is to compare the efficacy of Methotrexate vs Cyclophosphamide for Remission Maintenance in SNV.
The purpose of this study is to evaluate the safety, effectiveness, and side effects of the CryoSpray AblationTM System (CryoSpray AblationTM, "CSA" or "cryospray therapy") to treat benign airway disease in the lung using liquid nitrogen sprayed through a catheter via flexible fiber optic bronchoscopy (FFB)
