Investigation of Skin Prick Test in 664 Patients with Allergic Rhinitis

Objective The purpose of this study was to determine the distribution of inhalation and ingestion allergens among patients with allergic rhinitis from The Second Hospital of Tianjin Medical University.Methods A total of 664 allergic rhinitis cases diagnosed by the clinical history and presentation in the hospital were examined with the skin prick test(SPT) with 38 standardized aeroallergens,and the important sensitizing allergens were assessed.The cases were stratified based on gender and age.Difference of SPT responses among the groups was analyzed.Results The positive rate of SPT ranked as Dermatophagoides farinae(53.92%),Dermatophagoides pteronyssinus(47.29%),Plantain(34.19%),Candida albicans(32.38%),Mugwort(30.12%),Mycetes(23.95%).The positive rate of the SPT is much higher in the children group compared with adult(P0.05).The inhalant allergens were much higher compared with the food allergens(P0.05).There were no significant difference in the positive rate of allergens between male and female.Conclusion The inhalation allergens are the most important aeroallergens in Tianjin,and all of these the most important are dermatophagoides farinae and dermatophagoides pteronyssinus.
