- Abstract: BACKGROUND: Avoidance behavior against positive allergens detected by using multiple allergen simultaneous test (MAST)-immunoblot assay in patients with urticaria has been rarely reported. OBJECTIVE: We aimed to assess the avoidance behavior of patients with urticaria against positive allergens detected with a MAST. METHODS: One hundred and one urticaria patients who showed positivity to at least one allergen on a MAST completed a questionnaire regarding their test results. The avoidance behavior of the patients was evaluated, and relevant determining factors of avoidance success/failure were statistically assessed. RESULTS: We detected 144 different data (n=51, food allergens; n=17, pollen allergens; and n=76, aeroallergens) from 101 patients with urticaria. The avoidance failure rates were 33.3% for food allergens, 70.6% for pollen allergens, and 30.3% for aeroallergens. The pollen group showed a significantly higher avoidance failure rate than the food and aeroallergen groups (p<0.05). The patients with higher educational levels or more severe urticaria tended to successfully avoid allergens (p<0.05). The monthly household income level and patients' reliability to the test showed borderline correlations (p=0.057 and p=0.075, respectively). CONCLUSION: We believe that the results of this study could be helpful in predicting avoidance success or failure against allergens in patients with urticaria when clinicians conduct allergen-specific immunoglobulin E tests.
