[The significance of individual inhalation allergens in the sensitization of children with respiratory allergy].

Four hundred children were skin tested with following allergens: Dermatophagoides pteronyssinus, moulds, animal dander (mixture of dog, cat, sheep and horse dander), tree pollens, weed pollen (Ambrosia artemisifolia), and six grass pollens, as well as three nutritive allergens in children less than three years of age. Results demonstrated that in 200 children with perenial rhinitis and/or asthma. Dermatophagoides gave positive results in over 90%. In 200 children with pollen allergy, grasses were major allergens, and among them Timothy (Phleum pratense) gave over 90% of positive results. It is to be concluded than skin testing with many inhalatory allergens is not necessary in patients with typical clinical picture. Skin test with Dermatophagoides and Timothy should be done, and further evaluation taken into consideration only if these are negative.
