Background: Aspirin (ASA) desensitization and continuous daily ASA therapy is the criterion standard treatment for ASA-exacerbated respiratory disease (AERD). However, the optimal maintenance dosage of ASA and safety of "bridging" patients with AERD and with alternative cyclooxygenase-1 inhibitors for surgery have not been determined and require further investigation. Objective: This study was designed to compare the long-term effects of different maintenance doses of ASA and to assess the success of bridging subjects with AERD for surgery without losing desensitization. Methods: We retrospectively assessed 36 subjects with AERD who successfully underwent ASA desensitization from 2011 to 2017. We performed comprehensive medical record reviews and subsequent telephone interviews with a questionnaire. Results: Of 36 subjects, the average age was 52.8 years, with an average of 3.2 years since desensitization, and 65% were women. The subjects reported a decrease in frequency of nasal symptoms (p < 0.001), asthma symptoms (p = 0.016), and sinus infections (p < 0.001) after desensitization. Improvements were reported in sense of smell, taste, quality of sleep, and quality of life (p < 0.001) in all dosage groups. Thirteen subjects required stopping of ASA for surgeries. Six subjects (46%) were bridged with ibuprofen on an average of 5.9 days before surgery and restarted ASA on an average of 1.3 days after surgery, with no incidence of major adverse events or loss of desensitization. Seven subjects (54%) were not bridged, with three subjects restarting ASA after surgery without symptoms and four subjects losing desensitization. Conclusion: There did not seem to be a difference of benefits between 325 mg once or twice a day compared with 650 mg once or twice a day, but our small subject numbers made this conclusion difficult to prove. Desensitization improved subjective reporting on sleep quality as well as quality of life. Bridging the subjects with AERD who required surgery by using ibuprofen seemed to be safe and effective in maintaining ASA desensitization.
