Relationship Between Alcohol Intolerance and Aspirin‐Exacerbated Respiratory Disease (AERD): Systematic Review

Objective Previous studies have suggested that patients with aspirin‐exacerbated respiratory disease (AERD) have a high likelihood of alcohol intolerance. The purpose of this systematic review is to identify if there is sufficient evidence to confirm this correlation and the impact of medical therapy on subsequent alcohol tolerance. Data Sources PubMed, EMBASE, SCOPUS, EBSCO, Google Scholar, Cochrane Library, and Grey literature. We also performed snowballing on the identified observational studies (OS) for additional data. Review Methods A systematic review was conducted from 1968 to 2022 to identify those studies describing AERD symptomatology triggered by alcohol intake. The primary outcome was to analyze the current literature for the association between alcohol intolerance and AERD symptoms. The secondary outcome looked for improvement in alcohol tolerance after aspirin desensitization or biological therapy. Results A total of 775 studies were identified and 40 s were evaluated. From these, 5 studies met the inclusion criteria. Of the 5 manuscripts, there was 1 case‐control, 2 cohort, and 2 cross‐sectional studies. A total of 522 participants with AERD and a history of alcohol consumption were included, with 52.8% reporting at least 1 sinopulmonary exacerbation after alcohol intake. One of 3 studies noted improvement in alcohol tolerance after medical therapy with aspirin desensitization. Conclusion The current literature suggests that patients with AERD have a high risk of alcohol intolerance. Additionally, aspirin desensitization may improve alcohol tolerance in this patient population.
