Pulse therapy: Opening new vistas in treatment of pemphigus

Abstract

Pemphigus is comprised of a group of life-threatening autoimmune diseases that is characterized by circulating IgG antibodies targeting several types of keratinocyte antigens. After introduction of systemic steroids, survival has improved dramatically. However, mortality and morbidity were still very high due to side effects of steroids. Pulse therapy is defined as discontinuous/intermittent intravenous infusion of very high doses of corticosteroids along with certain immunosuppressive agents over a short period. This therapy was introduced to minimize the side effects of conventional corticosteroid therapy. The target is to achieve a faster response and stronger efficacy and to decrease the need for long-term use of systemic corticosteroids. As a result, this therapy has gained its popularity since three decades. The purpose of this article is to review the various available pulse therapy regimens with dosage, indications and contraindications and side effects.
