Abstract
We measured specific IgE antibodies (CAP-RAST) to Japanese cedar, Cryptomeria japonica, orchard grass, ragweed, mites and house dust 2, in order to elucidate the distribution of specific IgE antibodies to common aeroallergens in young male subjects in their 20s. The specific IgE antibody positive to Japanese cedar was present in 36.4% of the subjects ; that to mites, 33.1% ; and that to house dust 2, 35.5%. Regarding the relationship between self-reported allergic diseases and the specific IgE antibody, levels of specific IgE antibodies to Cryptomeria japonica, mites and house dust 2 were significantly higher in subjects with allergic diseases compared to those without. Levels of specific IgE to Japanese cedar, Cryptomeria japonica and mites were significantly higher in subjects with pollinosis compared to those without. These results indicate that Cryptomeria japonica, mites and house dust 2 influence allergic diseases, and Japanese cedar, Cryptomeria japonica and mites have an effect on pollinosis. We also confirmed the existence of subjects who were specific IgE-positive and symptom free, and subjects who were specific IgE-negative with symptoms.
