Diagnosis of Aspirin Hypersensitivity in Aspirin Exacerbated Respiratory Disease (ASAS)
Recruitment status was Recruiting
To diagnose aspirin hypersensitivity in asthmatics by using and safe, low-dose aspirin oral challenge.
Hypothesis 1: A low dose of oral ASA (20 or 40 mg) will induce significantly different concentrations of arachidonic acid metabolites in ASA-sensitive asthmatics as compared to ASA-tolerant asthmatics.
Hypothesis 2: The low dose (20 or 40 mg) ASA challenge will be well tolerated by ASA-sensitive asthmatics.
