Abstract:
Chronic urticaria is common and patients may present with transient eruption of itchy, eruthematous, edematous swellings of the dermis, which lasts more than six weeks. One type of chronic idiopathic urticaria, and part of it, is the chronic autoimmune urticaria. The chronic autoimmune urticaria is caused by high affinity of IgE receptors (anti-FcRI) and less frequently by anti-IgE autoantibodies, also the role of complement activation, that leads to mast and basophil activation. Despite many recent advances in the understanding of chronic autoimmune urticaria, this condition remains a major challenge in the terms of its etiology, investigations, and management.
