Prevalence of pollen sensitization in younger children who have asthma

Abstract

It is commonly believed that young children are incapable of pollen sensitization; therefore, skin testing usually is not performed to these allergens. The purpose of this study was to identify the frequency of positive skin tests to outdoor allergens among younger children who have asthma. Patients who have asthma, aged 6 months to 10 years, were evaluated for pollen sensitization over a 10-year period. Skin-prick testing was performed to relevant individual aeroallergens including trees, grasses, and weeds. Testing for perennial indoor allergens such as dust mites, cats, dogs, cockroaches, and molds was performed also. A total of 687 children with asthma were evaluated. No child <12 months old was sensitized to pollens. Children between 12 and 24 months of age had a 29% incidence of pollen sensitization. Three-year-old children were as likely to be skin test positive to pollen as an indoor allergen. Notably, 49% of 3- and 4-year olds were sensitized to outdoor allergens. Primary sensitizing pollens in this age group were short ragweed, box elder, and June grass. In this population, pollen sensitization was not related to tobacco or wood smoke exposure. Although it is widely believed that young children with asthma are most co...Continue Reading

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. Discover the latest research on atopic dermatitis here.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
