Filter by:Study of the efficacy of rituximab for maintenance treatment in systemic ANCA-associated vasculitis: prospective, multicenter, controlled, randomized comparative study of rituximab versus azathioprine
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)
To determine whether a combination of corticosteroids and azathioprine can achieve a higher remission rate and a lower subsequent relapse rate in patients with newly-diagnosed microscopic polyangiitis, polyarteritis nodosa or eosinophilic granulomatosis with polyangiitis (Churg Strauss syndrome) with no poor prognosis factor (FFS=0), and without significantly increasing the rate of adverse events, as compared to corticosteroids alone. The study hypothesis is a reduction of the absolute risk of treatment failure or relapse within the first 24 months following initiation of therapy of least 25%.
Wegener's granulomatosis is a primary systemic vasculitis characterized by granulomatous and necrotizing inflammation predominantly affecting the respiratory tract and the kidneys. Conventional therapy of Wegener's granulomatosis with cyclophosphamide and corticosteroids is limited by incomplete remissions and a high relapse rate. Patients accumulate irreversible damage due to the disease and the consequences of prolonged drug exposure. The efficacy and safety of an alternative immunosuppressive drug, gusperimus, was evaluated in patients with refractory disease. A prospective, international, nulti-centre, single limb, open label study. Entry required active Wegener's granulomatosis with a Birmingham Vasculitis Activity Score (BVAS) >=4 and previous therapy with cyclophosphamide or methotrexate. Immunosuppressive drugs were withdrawn at entry and prednisolone doses adjusted according to clinical status. Gusperimus, 0.5mg/kg/day, was self-administered by subcutaneous injection in six treatment cycles of 21 days with a seven day washout between cycles. Cycles were stopped early for white blood count < 4,000/mm3. The primary endpoint was complete remission (BVAS=0 for at least 2 months) or partial remission (BVAS<50% of entry score). After the sixth cycle azathioprine was commenced and follow-up continued for a further six months.
Wegener's granulomatosis (WG) is a rare disease that causes inflammation of blood vessels, or vasculitis. It may involve many different parts of the body, but typically affects the upper and lower respiratory tract and kidneys. The purpose of this study is to determine the safety and effectiveness of the medication abatacept in treating adults with mild relapsing WG.
A comparison of intermittent pulsed cyclophosphamide to daily oral cyclophosphamide for the treatment of ANCA-associated systemic vasculitides with kidney involvement. Performed by the European Vasculitis Study group.
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 aim of this trial is to lower the morbidity rate in elderly patients affected with systemic necrotizing vasculitides, by reducing mortality and improving global outcome.
The purpose of this study is to compare a 2 immunosuppressant regimen for the treatment of relapsing or refractory necrotizing antineutrophil cytoplasmic antibody (ANCA) associated vasculitides.
The purpose of this study is to determine wich treatment is the most effective in prevention of glucocorticoid-induced osteoporosis in patients with rheumatic diseases. The STOP-study: a randomized placebo controlled trial with alendronate versus alfacalcidol.
