[Asthma severity in relation to allergenic risk factors in childhood].
The majority of asthmatic patients are atopic--that is to say, they exhibit IgE-mediated sensitivity to common inhalant allergens. Exposure and sensitisation to allergens from the housedust mite has been established as an important risk factor in asthma in most parts of the world. The aim of our study was to assess total IgE and specific IgE on airborne allergens (Dermatophagoides pteronyssinus--DP, Dermatophagoides farinae--DF, mould, and grass pollen) in relation to asthma severity. The study involved 64 children with atopic asthma. Statistical significance was present between groups of intermittent and moderately persistent asthma for IgE and specific IgE on DP and moulds. In mild and moderate asthma, statistically significant differences were present for all parameters except for DF.
