Aeroallergen Specific IgE in Serum of Patients with Allergic Rhinitis / 中山大学学报(医学科学版)

ABSTRACT

[Objective] To study the aeroallergens in the patients with allergic rhinitis in Guangzhou.[Methods] Using the German screen allergens quantitative detection system to determinate serum aeroallergen specific IgE and total IgE levels of 625 cases with allergic rhinitis diagnosed in The Third Hospital of SUN Yat-sen University.The samples were stratified on two age groupsthe juvenile and the adult.Difference of serum aeroallergen specific IgE of the two groups was investigated.[Results]Aeroallergen specific IgE antibody in the serum of 625 patients with allergic rhinitis were positive.Total IgE in serum was positive in 413 cases,accounting for 66.1%.The positive rate of total IgE was less than that of aeroallergen specific IgE.The positive rate of aeroallergen specific IgE in order were mite mixture (84.32%),cockroach (19.04%),cypress (15.20%),cat-dog epithelia (13.12%),tree mixture (7.20%),ragweed (5.12%),humulus lupulus (1.76%),mugwort (1.76%),mould mixture (1.44%).In the two groups,the positive rate of aeroallergen specific IgE in order were similar.There were significantly higher sensitivity and positive rate of mite mixture in the juvenile group than the adult group (P ＜ 0.01).[Conclusion] The most important aeroallergens are mite mixture,cockroach,cypress,cat-dog epithelia,which could be referenced as Guangzhou patients .The juvenile is more sensitive to mite than the adult.
