RAST and PRIST in children with atopic dermatitis.

The study was carried out in 535 children. The frequency of positive RAST for food allergens decreased with age, whereas the frequency of positive RAST for inhalant allergens increased with age. Coexistence of asthma and/or rhinitis was not related to the results of RAST with food allergens. Positive RAST and multiple sensitivity for inhalant allergens were significantly greater in children with coexistence atopic respiratory disease. Total IgE was significantly higher in children with coexistent atopic respiratory disease in all age groups. This study provides information for the critical analysis of a RAST in atopic dermatitis.
