The evaluation of allergens and allergic diseases in children.
Knowing the incidence of allergic diseases and their relationship with allergens is a crucial requirement for therapeutic judgment. We present our experience on the incidence, clinical features and allergens of the allergic diseases detected by multiple allergosorbent chemiluminescent assay (MAST-CLA) in children from 1997 to 1999 at the Taipei Veterans General Hospital. The incidence of bronchial asthma, allergic rhinitis and atopic dermatitis are significantly different when stratified by age groups. Among the enrolled 2008 patients, 980 (48.8%) patients have positive MAST-CLA results. Of these, 562 (57.3%) are male and 418 (42.7%) are female. A significant increase among patients with positive allergens is also found when stratified by age group. Inhalant allergen is the major allergen detected in our patients. House dust mites Dermatophagoides pteronyssinus (Dp) and Dermatophagoides farinae (Df), cockroaches, feathers, and dog dander show the highest incidence in the 7- to 12-year-old group. In the fungal group, Aspergillus and Penicillium also show a significant difference in the incidence among different age groups. Pollen allergens, on a whole, show significant difference in incidence among different age groups. The food allergen group shows variable significant difference in incidence. Crab, milk, and egg white show the highest significant incidence in the 2- to 6-year-old group. These results suggest that the incidence of allergens detected in allergic diseases varies among different age groups.
