Abstract The aim of this study was to determine the aeroallergen sensitivity of allergic rhinitis patients. A total of 100 cases (female: 59, male: 41, aged between 10-59 years, mean age 27.9 years) who were diagnosed with allergic rhinitis by history and clinical presentation, underwent a prick skin test with 30 aeroallergens, and the important sensitizing allergens were assessed. Skin test reactivity showing > or = 3 mm wheal with erythema as the positive skin test, was recorded. The results of patients with positive skin tests follow. TREES: acacia 19\%, mango 16\%, coconut 12\%. GRASSES: bermuda 17\%, johnson 21\%, timothy 16\%, bahia 16\% orchard 18\%. WEEDS: pigweed 16\%, kochia 14\%. MOLDS: alternaria 11\%, cladosporium 11\%, aspergillus 12\%, penicillium 16\%, helminthosporium 16\%, botrytis 15\%, rhodotorula 20\%, fusarium 26\%, curvularia 26\%, smut mix 11\%, rust 9\%. EPIDERMALS: cat 29\%, dog 28\%, feathers 37\%. INDOOR ALLERGENS: house dust 72\%, D. pteronyssinus 76\%, D. farinae 79\%, American cockroach 60\%, German cockroach 41\%, kapok 30\%. Eighty-five percent of patients sensitive to house dust mites were positive to both D. pteronyssinus and D. farinae, indicating substantial cross-reactivity. The study shows that the house dust mite and the cockroach are important aeroallergen sensitizers among the Thai population, since more than half the patients were skin-test positive to the house dust mite and the cockroach.
