title: [Allergen skin tests to insects, chironomid, caddis fly and silkworm moth, in patients with nasal allergy].
abstract: The present study was undertaken to assess the importance of insects as allergens causing nasal allergy. We performed intradermal skin tests with extracts from three insects, chironomid, caddis fly, and silkworm moth, on patients with nasal allergy and on volunteers among medical students. Twenty-two (27.5%) of 80 nasal allergic patients showed positive reactions to chironomid allergen and 9 (11.3%) had positive reactions to caddis fly allergen and 18 (22.5%) to silkworm moth allergen. These positive rates were as frequent as those to Candida or ragweed. Medical students were divided into two groups, symptomatic and asymptomatic, according to the presence or the absence of nasal allergy. Three (11.5%) of 26 symptomatic group showed positive reactions to chironomid and one (3.8%) to caddis fly and 5 (19.2%) to silkworm moth. While even 4 (8.3%) of 48 asymptomatic group showed positive reactions to chironomid, 2 (4.8%) to caddis fly, and 6 (12.5%) to silkworm moth. These results suggested that these insects, chironomid, caddis fly, and silkworm moth, are relatively common than we expected and suspected as important allergens in nasal allergy.
