[Clinical implications of sensitization to inhalants in atopic dermatitis]

Abstract

In 104 children with atopic dermatitis (AD) and RAST tests for 2 inhalant and 9 food allergen mixtures, RAST results, severity of skin involvement and presence of respiratory symptoms by history were analyzed in addition to total serum IgE values available in 66 children. Overall frequency of sensibilization was high (74%) with more positive RAST results for foods than inhalants, although of the latter the only two tested were among the more frequently positive. When the subjects positive for inhalants were considered alone, the frequency of respiratory symptoms was significantly higher in those sensitized to both inhalant mixtures tested (dermatophagoides and graminaceae) and the presence of more severe skin lesions was more common among those sensitized to graminaceae.
