Aspirin-Exacerbated Respiratory Disease Management
Introduction to AERD
- Daily aspirin and ibuprofen use in an uncontrolled asthmatic is a critical red flag for AERD, a syndrome characterized by asthma, chronic rhinosinusitis with nasal polyps, and precipitation of respiratory reactions to aspirin and NSAIDs, according to the Journal of Allergy and Clinical Immunology 1
Rationale for Treatment
- Leukotriene modifiers are specifically recommended as pretreatment for patients with AERD to diminish respiratory responses, as stated by the Journal of Allergy and Clinical Immunology 1
- The addition of montelukast to high-dose ICS and LABA is a reasonable therapeutic option before considering biologics or further escalation, as recommended by the Journal of Allergy and Clinical Immunology 2 and 3
Diagnostic Considerations
- Testing for IgE and serum eosinophils should come after addressing obvious exacerbating factors, such as daily NSAID use, as suggested by the Journal of Allergy and Clinical Immunology 4
Treatment Implementation
- Immediately discontinue both aspirin and ibuprofen and counsel the patient on avoiding all COX-1 inhibiting NSAIDs, as advised by the Journal of Allergy and Clinical Immunology 1
- Start montelukast 10 mg daily, recognizing that the FDA has issued a boxed warning for neuropsychiatric events, as noted by the Journal of Allergy and Clinical Immunology 4
Follow-up and Outcomes
- Reassess asthma control in 2-6 weeks after NSAID discontinuation and montelukast initiation, as recommended by the Journal of Allergy and Clinical Immunology 4
- If asthma control improves significantly with NSAID avoidance and montelukast, this confirms AERD as a major contributor, although this specific fact is not directly cited, a similar recommendation is made by the Journal of Allergy and Clinical Immunology 4
Special Considerations
- Avoid substituting one NSAID for another, as cross-reactivity occurs with all COX-1 inhibitors, as warned by the Journal of Allergy and Clinical Immunology 1
- If aspirin desensitization is eventually considered, it must be done in a controlled setting with appropriate pretreatment including leukotriene modifiers and optimized ICS/LABA therapy, as stated by the Journal of Allergy and Clinical Immunology 1
