Detection of serum allergens in children with allergic rhinitis in Hangzhou
Objective To analyze the distribution of common allergens in children with allergic rhinitis(AR)in Hangzhou,and to provide reference for its prevention and treatment.Methods From January 2020 to December 2022,13 521 children who were diagnosed with AR and underwent in vitro serum specific immunoglobulin E(sIgE)detection in Affiliated Hangzhou First People's Hospital,School of Medicine,Westlake University were selected as the research objects.The positive rates of allergens in children with AR of different genders,ages and seasons were compared.Results Among 13 521 children,the positive rate of sIgE was 54.49%(7367/13 521),of which 64.82%were allergic to only one allergen.Among the 19 common allergens,the top three overall positive rates were household dust mite(44.27%),milk(14.62%),and mixed grass(4.82%).The positive rates of allergens of house dust mites,cat hair dander,mulberry,mold combination,tree pollen combination,amaranth,cockroach,milk,shrimp,crab,pineapple,shellfish and mango in male children were significantly higher than those in female children(P<0.05).The positive rates of allergens of house dust mite,mixed grass,cat hair dander,mulberry,mold combination,egg white,shrimp,crab,pineapple,cashew nuts and shellfish in different age groups were statistically significant(P<0.05).July and August were the two months with the highest allergen positive rate.The allergen positive rates of house dust mite,dog and cat hair dander were the highest in summer,and the allergen positive rate of plants was consistent with the flowering season.The sIgE concentration of house dust mite(77.87%)was mainly grade 3 and above.The sIgE concentration of other allergens was mainly grade 1 and 2.Conclusion Dust mites and milk are the most common allergens in children with AR in Hangzhou,and the distribution of allergens varies with gender,age and season.Allergen detection can provide a more accurate plan for the diagnosis,prevention and treatment of AR.
