Radioallergosorbent tests (RASTs) with five common foods were performed in 183 patients with atopic dermatitis. The results showed that about half of the patients had type I allergy to at least one of the five foodstuffs. The RAST results correlated roughly to the severity of dermatitis. In each group of patients with mild, moderate and severe atopic dermatitis, positive RAST reactions to common foods occurred predominantly in patients who had a personal or a family history of respiratory atopy. Positive RASTs were rare in patients with pure atopic dermatitis who had neither personal nor family history of respiratory atopy. It seems likely that type I food allergy occurs predominantly in those patients with atopic dermatitis who have a predisposition to respiratory atopy.
对183例特应性皮炎患者进行了针对五种常见食物的放射变应原吸附试验（RAST）。结果显示，约一半的患者对这五种食物中的至少一种存在I型过敏。RAST结果与皮炎的严重程度大致相关。在轻度、中度和重度特应性皮炎患者的每组中，对常见食物的RAST阳性反应主要发生在有个人或家族呼吸道特应性病史的患者中。在既无个人也无家族呼吸道特应性病史的单纯特应性皮炎患者中，RAST阳性很少见。I型食物过敏似乎主要发生在那些有呼吸道特应性倾向的特应性皮炎患者中。
