Steroid sparing in vasculitis: Myth or reality?

Abstract

Glucocorticoids are the cornerstone of therapy for all forms of vasculitis. However, glucocorticoid treatment carries with it the risk of glucocorticoid toxicity. Recent research efforts in vasculitis have emphasized investigation into strategies that reduce glucocorticoid exposure. These strategies include the adoption of rapid-acting steroid-sparing agents, reduced-dose glucocorticoid induction regimens, the early introduction of steroid-sparing agents for maintenance therapy, and the extension of maintenance therapy to minimize glucocorticoid exposure associated with disease relapse. These are critical advances to move us toward the goal of glucocorticoid-free treatment of vasculitis. The evidence supporting each of these strategies and directions for future research are explored.
