Background: Intranasal ketorolac challenges can induce respiratory reactions in patients with aspirin-exacerbated respiratory disease (AERD). Objective: To determine whether intranasal ketorolac challenges might be used for aspirin desensitization. Methods: One hundred patients with suspected AERD who were referred to Scripps Clinic from May 1, 2007 to December 31, 2009 were challenged with 4 increasing doses of ketorolac intranasally at 30-minute intervals. Symptoms, objective changes in the results of their nasal examination, peak nasal inspiratory flow rates, and forced expiratory volume in 1 second (FEV1) values were recorded. After nasal ketorolac dosing, patients were given oral aspirin as part of the challenge and desensitization. A control group consisted of 100 patients who had previously undergone our standard oral aspirin challenges and desensitization. Both groups were consecutively enrolled and had similar clinical characteristics. Results: Compared with the standard oral aspirin challenge and desensitization, intranasal ketorolac and modified aspirin challenge significantly attenuated the mean percentage decrease in FEV1 values (8.5% vs 13.4%; P = .01) and decreased the percentage of extrapulmonary reactions (23% vs 45%; P = .002), particularly laryngospasm (7% vs19%; P = .02) and gastrointestinal reactions (12% vs 33%; P = .001). This new protocol was significantly shorter, lasting an average of 1.9 vs 2.6 days (P = <.001). In fact, 83% of the patients completed the new protocol in less than 48 hours compared with only 20% in the oral challenge control group (P < .001). Conclusions: Intranasal ketorolac challenge and desensitization followed by rapid oral aspirin challenges is effective, safe, and less time-consuming than our standard oral aspirin desensitization protocol. © 2010 American College of Allergy, Asthma & Immunology.
