Desensitization to acetyl-salicylic acid as a treatment for non-steroid anti-inflammatory drugs (NSAIDs)-exacerbated respiratory disease The coexistence of hypersensitivity to acetylsalicylic acid (ASA) and other NSAIDs with disease of the upper or the lower airways (rhinosinusitis/sinonasal polyposis, or asthma) is defined as NSAIDs-exacerbated respiratory disease. Treatment options include the avoidance of all analgesics that inhibit COX-1 or ASA desensitization, continuing its daily consumption. The latter treatment has shown to improve quality of life, reduce the formation of sinonasal polyps, the episodes of sinus infection, the frequency of hospitalizations and surgeries for resection of polyps and the need for systemic steroid treatment. Multiple desensitization schedules have been used, trying to reduce the risk associated with the procedure and the adverse effects of chronic use of ASA. In this paper we present a review of the different methods of desensitization and two illustrative clinical cases to help understand the factors that influence the choice of treatment for these patients.
