Abstract

Two patients who suffered from allergic rhinitis, conjunctivitis and contact urticaria caused by the two-spotted spider mite (Tetranychus urticae, Koch) are described. Both patients worked in a greenhouse where they came in contact with both spider mites and predator mites living on bean leaves. Prick, Prausnitz-Küstner and RAST tests indicated type I allergy to spider mite but not to predator mite. Both patients had a high level (RAST score 4) of spider-mite-specific IgE in their sera. Radioallergosorbent test (RAST) inhibition studies revealed no cross-reactivity between spider mite and house dust mite allergens. These results show that spider mites, which are herbivorous mites found in nature, in greenhouses and even in homes, can cause IgE-mediated allergy in man.

摘要

本文描述了两名因二斑叶螨（Tetranychus urticae, Koch）引起过敏性鼻炎、结膜炎和接触性荨麻疹的患者。两名患者均在温室工作，在那里他们接触到生活在豆叶上的叶螨和捕食螨。点刺试验、普劳茨-屈斯特纳试验（被动转移试验）和放射变应原吸附试验表明，患者对叶螨呈I型过敏，而对捕食螨不过敏。两名患者血清中叶螨特异性IgE水平较高（放射变应原吸附试验评分4级）。放射变应原吸附试验（RAST）抑制研究表明，叶螨和屋尘螨变应原之间无交叉反应性。这些结果表明，叶螨这种在自然界、温室甚至家庭中均能发现的食草螨，可在人类中引起IgE介导的过敏反应。
