Aspirin-exacerbated cutaneous disease

Abstract

It has been recognized that a high proportion of chronic urticaria patients experience symptom aggravation when exposed to aspirin and NSAIDs. This clinical picture is known as Aspirin-exacerbated cutaneous disease. The pathogenesis of these exacerbations is related to the inhibition of cyclooxygenase-1 leading to a decreased synthesis of PGE2 and an increased cysteinyl leukotriene production in the skin and subcutaneous tissues. Patient management comprises the treatment of the underlying cutaneous disease with nonsedating antihistamines and other medications, avoidance of COX-1 inhibitors, and the use of alternative NSAIDs that do not inhibit COX-1 for the relief of pain, inflammation and fever.
