We evaluated the 29 children – 14 with Severe Asthma (SA) and 15 with moderate asthma – control group (CG). All children were tested for specific IgE. All SA children had concomitant allergic rhinitis in contrast to only 2 (13,3%) with CG. Higher eosinophil levels were found in SA group (p<0,05). 92,85% from SA group and 33.33% in CG had minimum 1 elevated antigen titer. The most common clinically significant allergens in SA were dermatophagoides, grass mix and cat, followed by alternaria and birch. Precise allergen detection could help for recommendation plan in patients who are unable to be tested.
