Appreciable numbers of aspirin-sensitive asthmatic patients have chronic severe asthmatic symptoms. We report two cases of aspirin-sensitive asthmatics with mild asthmatic symptoms, whose methacholine PC20 levels were 9.07 and 7.06 ㎎/㎖ at first visit. The aspirin sensitivity was confirmed by lysine-aspirin bronchoprovocation at initial diagnosis. After anti-asthmaitc medications and avoidance of salicylate-containing agents, respiratory symptom, airway hyperresponsiveness, and aspirin sensitivity disappeared after 33 and 45 months. These results suggest that early detection and careful avoidance of salicylate-containing agents may have beneficial effects resulting in resolution of airway hyperresponsiveness and aspirin sensitivity in aspirin-sensitive asthmatic patients.
