Mechanisms of Alcohol Sensitivity in AERD

Not Applicable

• Conditions: Aspirin-Sensitive Asthma With Nasal Polyps; Samter's Syndrome

• Registration Number: NCT03441438
• Lead Sponsor: University of Virginia

Brief Summary

The purpose of this study is to determine what type of reactions in the body may be responsible for the respiratory symptoms that occur when patients with Aspirin Exacerbated Respiratory Disease (AERD) drink alcoholic beverages. These reactions are most often seen with red wine.

Detailed Description

This is a prospective trial of approximately 60 subjects with AERD to explore the mechanisms behind the physiologic reactions that occur when drinking alcoholic beverages. At various time points patients will be asked to ingest a variety of substances found in red wine after which blood and urine markers of the reaction will be measured.
