Abstract | 近年ユスリカが気管支喘息の原因抗原となり得ることが報告されている。しかし,その臨床的特徴はいまだ明らかにされていない。このユスリカ抗原の特徴を検討する目的で,気管支喘息症例163例をHD(ハウスダスト)に感作されたRAST score2+以上の陽性例82例とscore1+以下の陰性例81例とに分けて比較検討を行なった。その結果皮膚反応,ヒスタミン遊離,CTT抗原を用いた特異的IgE抗体いずれの検討においても,HDに感作された症例が,よりユスリカ抗原にも感作されやすいことが明らかになった。

抄録(別言語) | In recent years it has been reported that chironomid migdes might be one of the causative allergens in bronchial asthma. In order to clarify the clinical characteristics of bronchial asthma induced by chironomid midges (Tokunagayusurika akamusi), 163 patients with bronchial asthma were studied. The subjects were divided into two groups ; cases with negative (0~1 + ) and positive (2 + or more) RAST score to house dust. 1. Skin reaction to midges was positive in 54 cases (33.1%) out of 163 patients with bronchial asthma. Thirty-six cases (43.9%) out of 82 asthmatics with positive RAST score to house dust showed positive skin reaction to midges, but in 81 cases with negative RAST score, only 18 cases (22.2%) showed positive skin reaction. 2. Fourteen cases out of 85 asthmatics showed a significant amount of histamine release (more than 15%). A significant amount of histamine release was observed in 12 cases (23.5%) out of 51 cases with positive RAST score, but in only two cases (5.9%) out of 24 cases with negative RAST score. 3. Specific IgE antibodies to CTT (Chiromonus thummi thummi) was positive in 12 cases (18.2%) out of 66 asthmatics. In 41 asthmatics with positive RAST score to house dust, 12 cases (29.3%) showed positive RAST score to CTT, though in 25 cases with negative RAST score to house dust no cases showed positive RAST score to CTT. In conclusion, cases with house dust allergy were more easily sensitized by chironomid migdes than those cases without house dust allergy.
