Abstract:
Objective To investigate the role of molecular allergen diagnosis in respiratory allergic diseases, and measure the prevalence and the allergen molecular mapping of the asthma and allergic rhinitic patients.Methods Totally 80 cases of asthma or allergic rhinitis patients with two or more inhaled allergens from First Affiliated Hospital of Guangzhou Medical University during 2013 January to 2014 December were tested for serum specific immunoglobulin E ( sIgE ) against 112 allergen components by ImmunoCAP ISAC.Results About 78.8% ( 63/80 ) patients is three or more allergen components sensitization, the most prevalence allergen components were house dust mites′Der f 1 67.5%(54/80), Der f 2 66.2%(53/80), Der p 1 and Der p 2 were 63.8%(51/80) and 61.2%(49/80), Der p 10 was only 12.5%(10/80), follewed by Fel d 1 22.5%(18/80), Cyn d 1 16.2%(13/80), Phl p 4 15.0%(12/80), Pen m 1,Pla a 2,Jug r 2 and Can f 1were all 11.2%(9/80), Lep d 2, Blo t 5, Bla g 7 and Ani s 3 10.0%(8/80).Other allergen components positive rates were low.Conclusions Molecular allergen diagnosis can provide more comprehensive diagnostic information for allergic patients, by providing allergen map.Allergen microarray can discover the neglected allergens such as bermuda grass, timothy grass and plane tree pollen allergens in southen China.
