ABSTRACT
Objective To investigate the sensitization pattern of Blomia tropicalis in patients with aller-gic respiratory disease and the association between Blomia tropicalis with allergic rhinitis and / or asthma. Meth-ods 330 allergic rhinitis and / or asthma patients sensitized with mites were selected in Guangzhou,and sIgE lev-el in the serum of all recruited patients of Blomia tropical,Dermatophagoide pteronyssinus and Dermatophagoide fa-rina was measured. Results The sensitization rate of Blomia tropicalis was significantly lower than that of Derma-tophagoide pteronyssinus and Dermatophagoide farina(P < 0.001,both). 80.0% Patients were sensitized with both three mites,and only 0.3% patients were of monosensitization to Blomia tropicalis. The sIgE of these three mites were significantly positive correlated with each other(P < 0.001),Dermatophagoide pteronyssinus and Derma-tophagoide farina have strong correlation(r = 0.906),Blomia tropicalis has moderate correlation with Dermatopha-goide pteronyssinus and Dermatophagoide farina(r = 0.540 and r = 0.512,respectively). With the increase of Blomia tropicalis sIgE,the severe sensitization rate(sIgE level:class 5~6)of patients sensitized combined Der-matophagoide pteronyssinus or Dermatophagoide farina significantly increased(P < 0.001). The sIgE level of Der-matophagoide pteronyssinus and Dermatophagoide farina in allergic asthma and rhinitis patients were significantly higher than that of patients with rhinitis or asthma alone(P < 0.001),and the sIgE level of Blomia tropicalis in pa-tients with both allergic asthma and rhinitis or with asthma alone were also significantly higher than that of patients with rhinitis alone(P = 0.006 and P = 0.020,respectively). Conclusion The Blomia tropicalis sensitized pa-tients usually sensitize together with Dermatophagoide pteronyssinus or Dermatophagoide farina,and the degree of Blomia tropicalis sensitized in asthma patients are higher.
