title: Perspective on future therapy of vasculitis.
abstract: This article summarizes recent advances in the management of various vasculitic syndromes and discusses potential new therapies based on a better understanding of their pathogenesis and natural history. Current efforts for optimization of testing for antineutrophil cytoplasmic antibodies and improvement of diagnostic criteria will certainly have a significant impact on future therapy. Biologic agents such as interferon-alpha are already in use in various vasculitides, whereas others, such as inhibitors of tumor necrosis factor-alpha, are in phase I clinical trials. Agents that selectively inhibit distinct steps in the pathogenesis of vasculitis are in preclinical or early clinical stages of development. Newer (mycophenolate mofetil, leflunamide) or older (methotrexate, azathioprine) immunosuppresive agents are finding new roles in the management of vasculitides. For patients with severe vasculitis, short-term use of cytotoxic agents, such as cyclophosphamide, alone or in combination with biologic agents, may expedite remission, which could then be better maintained with other, less toxic (and less expensive) immunosuppressive agents, such as methotrexate, azathioprine, mycophenolate mofetil, and leflunamide. For patients with mild or moderately severe vasculitis, these latter agents alone may be adequate. New therapeutic studies in vasculitis should better address the impact of therapy on health-related quality of life and its long-term toxicity.
