Abstract
Background: Both indoor and outdoor allergens are an important risk factor in atopic disease development. There is no data about the prevalence of skin test positivities to aeroallergens in children with atopic disease in Surin Provine.
Objective: To detect the prevalence of skin test positivities to indoor and outdoor allergens in children with atopic disease
Setting: Pediatric allergy clinic, Surin Hospital.
Research Design: Cross-sectional Discriptive Study
Method: Children with allergic rhinitis, allergic conjunctivitis, allergic rhinoconjunctivitis,
atopic dermatitis and asthma at Surin Hospital were enrolled. Skin test with indoor allergen, molds and grass pollens were performed by stallerpointes and interpreted according to the standard procedure. SPSS version 11 was used to analysed the data.
Results: There were 173 patients (64.74% male (112case), 35.26% female (61cases))
with average age of 8.46 years. Among the 173 patients, 129 (74.6%) had at least one positive skin prick test reaction. The most frequent allergens were Dermatophagoides pteronyssinus (60.7%) follow by Dermatophagoides farinae (56.6%), mixed cockroach(47.4%), Johnson grass (37.0%), Bermuda grass (30.0%), Cat (18.5%), Dog (7.5%) and Mold (4.6%). Prevalence of positive skin prick test to pollens were significantly increased according to allergic conjunctivitis, allergic rhinoconjunctivitis (odd ratio 4.350, 2.650) respectively.
Conclusion: The prevalence of skin test positivity at least one allergen in children with allergic disease at Surin Hospital was 74.6%. Dermatophagoides pteronyssinus, Dermatophagoides farinae, mixed cockroach, Johnson and Bermuda grass were the five most common allergens. Allergic conjunctivitis and Allergic rhinoconjunctivitis had risk factor for positive skin test to grass pollens.
