Aspirin-induced asthma as a risk factor for asthma mortality.
We have recently reported severe airway obstruction and bronchial hyperresponsiveness (BHR) in fatal asthma compared with patients without a history of near-fatal asthma. Based on these findings, we evaluated whether aspirin-induced asthma (AIA) is a risk factor for asthma mortality by analyzing pulmonary function and BHR. FEV1.0% and methacholine inhalation threshold were significantly lower in the fatal asthma group compared with the AIA and non-AIA groups. However, there were no significant differences between the AIA and non-AIA groups. Our results suggested that AIA is not a risk factor for asthma mortality if avoidance of aspirin and aspirin-like drugs is assured.
