Filter by: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 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 purpose of this study is to investigate whether abatacept can prevent relapse in patients with ANCA associated vasculitis(AAV). This is a randomised double blinded placebo controlled trial.
The aim of this study is to study the efficacy of intravenous immunoglobulins for inducing remission in patients relapsing of systemic vasculitides.
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).
