[Prevalence of mite hypersensitivity in children with asthma].

Abstract

By skin prick test, three kinds of mite allergens (Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tropicalis) were tested in a group of asthma children in Jinhua area from Oct 2005 to Sep 2006. The positive rate to allergen from D. pteronyssinus and D. farinae was 80.6% and 77.8% respectively, higher than that of Blomia tropicalis (61.1%) (chi2 = 21.39, P < 0.05). Cases positive to Blomia tropicalis allergen showed 100% and 95.9% positive reaction to D. pteronyssinus and D. farinae respectively. The results demonstrated that the important allergens for children's asthma are from D. pteronyssinus and D. farinae, while the with the former two mite allergens. Blomia tropicalis allergen is supposed to have cross-reactivity
