[Aspirin-sensitive urticaria; a clinical study].

In the paper clinical characteristics of patients with aspirin-induced urticaria were performed. The group of 71 patients, 49 women (69%) and 22 men (31%), mean age of sensitivity symptoms demonstration--32.5 years, underwent allergological, laryngological and histamine dihydrochloride inhalatory tests. Nasal polyps were found in 2 persons (2.8%), atopic diseases in 23 persons (32.3%) and at least one feature of atopy in 37 persons (51.9%). 49 subjects (69%) suffered from urticaria which was not associated with ingestion of aspirin. In 22 patients urticaria developed solely due to aspirin. Urticaria not associated with aspirin had been presents for 2 weeks to 30 years before the onset of sensitivity to aspirin. The authors conclude that aspirin-sensitive urticaria results from concomitance of two different phenomena in one person, i.e. sensitivity to aspirin and urticaria not associated with ingestion of the drug.
