Urticaria: an immunologist's viewpoint

AYY Wu 鄔楊源

Abstract
Urticaria is one of the most commonly encountered chronic conditions in clinical practice. The aetiology of urticaria is diverse, but can be broadly classified into allergic, autoimmune and physical causes. Successful management depends on accurate diagnosis. In allergic urticaria, identification of causative agents and education on avoidance can often ameliorate the problem. Idiopathic or autoimmune urticaria is initially best managed symptomatically, as most of these cases will spontaneously remit, whereas patients with urticarial vasculitis often require immunomodulatory drug treatment.
