Abstract：ObjectiveTo investigate the inhalant allergen spectrum in patients with allergic rhinitis in Beijing Daxing District.MethodsA sensitive quantitative allergen screen system(Allergy Screen)was used in 1200 patients with allergic rhinitis to test the sIgE of inhalant allergens. The patients were divided into two groups according to their ages,group A(3~18 years old)and B(18~82 years old). And the distribution of inhaled allergens of the two groups was compared.ResultThe most common allergen found in group A was mixed fungi(61.26%),followed by house dust mite(57.47%)and house dust(38.32%)etc.The most common allergen found in group B was house dust mite (67.45%),house dust(58.48%),followed by and mixed fungi(35.72%)etc.The top three allergens whose sIgE≥III were mixed fungi(62.89%),house dust mite(56.41%) and mugwort(52.13%)in group A;and house dust mite (60.74%),dwarf ragweed(48.33%)and cockroach (41.38%)in group B. As for dual positive allergens in all patients,the most common allergen combination was mixed fungi + house dust mite,house dust mite + house dust and house dust mite + cockroach.ConclusionThe house dust mite,house dust and mixed fungi were the most important three aeroallergens in Beijing Daxing District. However,the pathogenic allergens were different in patients with different ages.
