Examination of allergen specific IgE antibodies by CAP-RAST in 2000 and 2001 *
Inspection pf specific serum IgE antibodies using the CAP-radioallergosorbent test and the CAP method was carried out by the Department of Otolaryngology of Kawasaki Medical School in 2000 and 2001. A comparison of the results for 2000 with those for 2001 revealed an increase in the scattering of Japanese cedar and cypress pollen. As a result, many antibody positive persons for Japanese cedar pollen were seen. On the other hand, the rate of perennial antibody positive persons, such as house dust and mites, decreased. There was no change in the rates of insect antibody positive persons, such as from cockroaches and midges, and mold, regardless of the change in the amount of pollen. In addition, in Okayama Prefecture, as the rates of Japanese cedar pollen antibody positive persons have increased, those for ragweed and mugwort have decreased since ten yearsago. It might be useful for both medical participant and allergic rhinitis patients to be continuously aware of the transition in the rates of antibody positive persons. (Accepted on December 17, 2003)
