Urticaria is a disorder of the skin and mucosal tissues characterized by the occurrence of wheals, angioedema, or both, the latter defining the urticaria-angioedema syndrome. Approximately 12–22% of the general population has suffered at least one subtype of urticaria during life, it is usually self-limited and resolves spontaneously without requiring medical attention. A recent Italian study, based on the consultation of a national registry, reported that there is a prevalence of chronic spontaneous urticaria (0.02% to 0.4%) and an incidence of 0.1–1.5 cases/1000 inhabitants/year.
The researchers found the required data by reviewing the recent international guidelines about urticaria and after that, they described a methodologic approach based on classification, pathophysiology, impact on the quality of life, diagnosis and prognosis, differential diagnosis, and management of all the types of urticaria.
The aim of the present document from the Italian SIAAIC and the Italian Society of Allergological, SIDAPA is to provide updated information to all physicians involved in the diagnosis and management of urticaria and angioedema.
