Aspirin-Exacerbated Respiratory Disease Defined
Aspirin-exacerbated respiratory disease (AERD), also known as Samter’s Triad, is a chronic medical condition that consists of three clinical features: asthma, sinus disease with recurrent nasal polyps, and sensitivity to aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) that inhibit an enzyme called cyclooxygenase-1. This sensitivity usually manifests as respiratory reactions that occur upon ingesting or inhaling an NSAID, though the exact cause of the reactions is not known. Approximately 9% of all adults with asthma and 30% of patients with asthma and nasal polyps have AERD. In general, AERD develops quite suddenly in adulthood, usually between the ages of 20 and 50, and there is no clearly understood trigger that causes the disease.
