Active clinical trials for "Granulomatosis with Polyangiitis"

Remission of ANCA-associated vasculitis can be obtained in approximately 80% of the patients with a combination of corticosteroids and cyclophosphamide. However, relapses are frequent. This point warrants the prescription of a maintenance treatment with a less toxic immunosuppressant for several months to years. The optimal drug in this indication is not determine. We decided therefore to compare the 2 most used drugs in this indication. Induction therapy consists in the combination of corticosteroids and intravenous cyclophosphamide pulses. Corticotherapy consisted first in one daily methylprednisolone pulse, for 1 to 3 days, followed by oral prednisolone at the dose of 1 mg/kg/d for 3 weeks, then progressively tapered and stopped at the 18th month from the diagnosis. Cyclophosphamide is administered every 2 weeks for the first 3 bolus (0.6 g/m2 - D1, 15 and 30), then every 3 weeks (0.7 g/m2). Once remission is achieved, patients receive 3 additional bolus (0.7 g/m2). At that time, patients are randomized for a maintenance treatment with azathioprine (2 mg/kg/d, orally) or oral methotrexate (starting at the dose of 0.3 mg/kg/wk, then progressively increased every weeks by 2.5mg, if necessary, to a maximum and optimal dose of 25 mg/wk) for 12 months.

The ultimate goal of this prospective natural history study is to define the natural history of the obstructive airway manifestations of Granulomatosis with polyangiitis (GPA). Additionally this proposal seeks to develop biomarkers of disease activity and define their correlation with clinical outcomes in an effort to transform clinical care and shape future drug development for this devastating rare disease.

A cross-sectional study design and online questionnaire was used to assess the informational needs of patients with several different types of systemic vasculitis. Patients were recruited from within the Vasculitis Clinical Research Consortium (VCRC) online Patient Contact Registry1. Survey responses from participants in the VCRC Patient Contact Registry were compared to responses from a similar survey recently administered to patients within a United Kingdom (UK) based vasculitis support group (Vasculitis UK).

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.

Granulomatosis with polyangiitis (Wegener's) (GPA) and microscopic polyangiitis (MPA) are two rare immune system disorders that cause the inflammation of blood vessels, or vasculitis. In order to properly treat these diseases, it is critical that the level of disease activity can be determined over the course of the disease. The purpose of this study is to determine new biological markers, or biomarkers, that may be used to assess the severity of disease in people with GPA or MPA.

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.

The purpose of this study is to learn about how patients with vasculitis think about their illness and to assess to what extent patient perceptions of illness are associated with physical, mental, and social functioning

This study seeks to understand the journey that patients eventually are diagnosed with vasculitis experience in the period prior to their formal diagnosis by a healthcare provider. Data elements of interest include average time from the onset of the first symptoms to the time a diagnosis of vasculitis is confirmed. Other aims include identifying factors associated with the time to diagnosis. These factors will be divided into: a) intrinsic factors, or so-called "patient-related factors", such as the type of vasculitis symptoms, patient demographics, socioeconomic status, patients' beliefs regarding the etiology of their symptoms, and other factors, and b) extrinsic factors, or "professional/health system factors", such as healthcare access, referral patterns, testing patterns, and other factors. Understanding such factors can guide future efforts to shorten delays in diagnosis and thereby improve outcomes. All analyses will be done for the population of patients with vasculitis as a whole and by individual types of vasculitis.

The purpose of this study is to learn about reproductive health, including fertility and pregnancies, in people with vasculitis.

Granulomatosis with polyangiitis (GPA) is one of antineutrophil cytoplasmic autoantibody (ANCA) - associated vasculitis. Inflammation-induced thrombosis is considered to be a feature of systemic autoimmune diseases. GPA usually involves the upper and lower respiratory tract and renal systems, where necrotizing glomerulonephritis and pulmonary capillaritis are often detected. However, it may also affect other organ systems. Cardiac involvement in GPA occurs in approximately 6% to 44% of cases and is secondary to necrotizing vasculitis with granulomatous infiltrates. Cardiac involvement is an independent predictor of mortality in GPA patients. In this prospective cohort study, consecutive GPA patients who were hospitalized in the Department of Family Medicine, Internal and Metabolic Diseases at the Medical University of Warsaw in Poland are included. In all patients echocardiography and laboratory tests are perform.
