[Allergen detection and etiological study of adenoidal hypertrophy in children]

Objective:To investigate the etiology of adenoidal hypertrophy by detection of allergen and total serum IgE in children.Method:Using the German Allergy Screen Test Kit testing system, total serum IgE was detected and quentitative detection of allergen specific IgE in 19 groups in 782 children with adenoidal hypertrophy, the proportion of total IgE in serum and the positive rate of allergens were counted, the proportion of atopy and the characteristics of the allergens were analyzed. Result:The proportion of total IgE in serum of 782 children with adenoidal hypertrophy was 66.8%. The top ten allergens (by positive rate) were: milk（32.0%），house dust mite（27.7%），moulds（25.3%），dog hair（22.4%），egg whites（16.5%），cashew nuts（10.5%），house dust（10.4%），cat hair（9.5%），crab（5.1%），beef（3.7%）. Conclusion:In present study, 66.8% adenoidal hypertrophy children with atopy. The following inhalation allergens positive rate of top three in children with adenoidal hypertrophy are: house dust mite, moulds, dog hair. The positive rate of food intake of the first three are: milk,egg whites, cashew nuts.
