[The study of 18 cases of aspirin urticaria at dermatology of Yodogawa Christian Hospital--on the difference between aspirin asthma and aspirin urticaria].
Aspirin intolerance manifests itself as two clinical symptoms, urticaria/angioedema and asthma. However, there is seldom patient of aspirin intolerance who has the both symptoms, urticaria and asthma. So we suspect that the pathogenic mechanism for aspirin urticaria differs from that for aspirin asthma. We examined 18 patients of aspirin urticaria at dermatology of Yodogawa Christian Hospital, especially as to oral aspirin challenge test. All patients had no symptom of asthma. Threshold dose evoke urticaria/angioedema after ingesting 100 to 500 mg of aspirin (average, 311 mg). Urticaria/angioedema occurred within 50 minutes to 14 hours (average, 3 hours 16 minutes) after ingesting aspirin. The dose and the time of oral aspirin challenge test for these 18 patients were more spent than those for reported patients of aspirin asthma. These results support the opinion that aspirin urticaria has the different pathogenic mechanism from aspirin asthma. In addition, we experienced one patient of aspirin intolerance which caused hyperemia and edema of the bulbar conjunctiva. She had no symptom of urticaria and asthma, and had the both character of aspirin urticaria and asthma as to aspirin challenge test. We propose that aspirin intolerance is classified in reaction of the skin (urticaria/angioedema) and reaction of the mucosa (asthma), and it has an intermediate type.
