Urticaria crónica espontánea: revisión de la literatura

Abstract: Chronic spontaneous urticaria is a disease that produces a great compromise in patient's quality of life. The associated pathophysiological mechanisms are still largely unknown because they are not generalizable to all individuals. There are intrinsic and extrinsic factors involved in the development and persistence of the disease that can act individually or coexist. In this review are proposing some changes in the current classification of the disease, which includes a subdivision into the chronic urticaria called mixed chronic urticaria that makes reference to cases where intrinsic and extrinsic factors coexist for the onset of the disease in the same individual. Some viral, bacterial and parasite infectious processes have been associated with the development or severity of chronic urticaria symptoms in a subgroup of patients, therefore, they are included as extrinsic factors to the individual within chronic inducible urticaria non-physical. These modifications are proposed in order to optimized the diagnosis and treatment of patients with chronic spontaneous urticaria. (AU)
