Abstract:
Objective To analyze the results of inhaled allergens detection in children with allergic rhinitis(AR)in Changzhou ar-ea and the distribution situation of allergens in different age groups.Methods The levels of serum allergen specific IgE antibodies in 473 children cases(aged 1-12 years)of allergic rhinitis(AR)were detected by the Allergy Screen allergen screen system.The children cases were divided into the infants group(0-3 years old),preschool children(4-6 years old)and school age children(7 -12 years old)according to age.The allergen positive rates and the change tendency were compared among different age groups.Re-sults Among 473 children cases of allergic rhinitis,340 cases(71.9%)were positive.The top three allergens were house dust mite (55.6%),mixed fungi(25.8%)and house dust(18.8%).The positive rate of allergen showed the upward trend with the age in-crease.The distribution of house dust mite(χ2 =21.061,P =0.000),house dust (χ2 =15.111,P =0.000)and the cat and dog dan-der(χ2 = 7.597,P = 0.022 )was statistically significant among the three groups.Single allergen positive rate was the highest (38.5%)and the secand was double allergens(23.7%).The top three positive in single allergens was consistent with sort of total allergen positive rate.The most common double allergen was the combination of house dust mites and house dust.The multiple al-lergen positive rate had statistical significance in the distribution among groups(χ2 =13.399,P =0.001).Conclusion The inhaled allergens of AR children in Changzhou area are dominated by house dust mite,mixed fungi and house dust.The positive rate shows the increasing trend with age increase.The allergen constituents are different in different age groups.The positive single allergen is most common,followed by positive double allergens.
