Autoimmunity and complement in the pathogenesis of chronic urticaria

Alexander M Marsland. Curr Allergy Asthma Rep. 2006 Jul.

Abstract

Chronic urticaria is a debilitating skin disease that is believed to have an underlying autoimmune etiology in 35% to 50% of cases. Patients with autoimmune urticaria have functional antibodies in their sera that release histamine from basophils and mast cells. The C5a component of complement is required for mast cell degranulation in this process and at least augments basophil histamine release. In this article, the evidence that is key to our understanding of autoimmunity and complement in the pathogenesis of a subset of patients with chronic urticaria is outlined. Some of the issues in testing for and treating autoimmune urticaria are discussed.
