Abstract:
OBJECTIVE To analyze the results of the inhalational allergen detection in children with allergic rhinitis in Tianjin, and to understand the common allergens and their distribution.METHODS Mediwiss (Screen Allergy) was used to determine the specificity of allergen specific IgE in serum. According to sex, age, season, the distribution of allergens was described.RESULTS The most common inhalant allergens in Tianjin were mixed fungus(52.35%), followed by Dermatophagoides pteronyssinus(35.88%), dog dander(24.31%), cat dander(15.10%). The positive single allergen(59.03%) was most common, followed by positive double allergens(25.88%); The positive rate of the boy with inhalation allergen was higher than that of the girl; The positive rate of the inhalation allergen in the infant stage was significantly lower than that in the preschool, the school age, and the adolescent; In summer, the inhaled allergens positive rate was significantly higher than that in winter and spring, above differences were statistically significant(P<0.05). CONCLUSION Mixed fungus, Dermatophagoides pteronyssinus, dog and cat dander are the most common inhalant allergens in children with AR in Tianjin area. The positive rate of allergens has certain regularity in sex, age and season.
