Aspirin-sensitive rhinosinusitis: the clinical syndrome and effects of aspirin administration.

Nineteen aspirin sensitive adult patients were identified who experienced naso-ocular responses without associated bronchospasm during standardized oral aspirin challenge. These 19 patients exhibited the characteristics of the aspirin triad except asthma. These included hypertrophic rhinitis with or without associated nasal polyps, abnormal sinus roentgenograms, nasal eosinophilia, aspirin-provoked responses of the upper airway identical to those observed in aspirin-sensitive asthmatics, capacity of the upper airway to be desensitized to aspirin, and cross-reactivity and/or cross-desensitization of the upper airway to indomethacin. Of the 17 patients who were treated with daily aspirin after desensitization, 77% experienced improvement in their nasal symptoms.
