33 名特应性皮炎患者接受了双盲安慰剂对照食物挑战,以评估组胺在食物过敏中的作用。排除可疑食物 10 天后,用最多 8 克脱水食物进行口服挑战。总共 35 次阳性挑战在 10 至 90 分钟内引发了皮肤 (31)、胃肠道 (17)、鼻 (8) 和呼吸道 (6) 症状。 41 项食物挑战呈阴性,所有 60 项安慰剂挑战均呈阴性。只有食物挑战呈阳性的患者组血浆组胺浓度平均 (±S.E.M.) 显着上升,从挑战前的 296±80 pg/毫升上升到挑战后的 1055±356 (P<0.001)。在这些积极的口服食物挑战后观察到的血浆组胺升高表明肥大细胞或嗜碱性粒细胞介质参与了食物过敏的发病机制,包括特应性皮炎患者的皮肤变化。 (新英格兰医学杂志 1984 年;311:372-6。)
Thirty-three patients with atopic dermatitis underwent double-blind placebo-controlled food challenges for evaluation of the role of histamine in hypersensitivity to food. After suspect foods were eliminated for 10 days, oral challenges were performed with up to 8 g of dehydrated food. A total of 35 positive challenges elicited symptoms that were cutaneous (31), gastrointestinal (17), nasal (8), and respiratory (6) within 10 to 90 minutes. Forty-one food challenges were negative, and all 60 placebo challenges were negative. Only the group of patients with positive food challenges had a significant mean (±S.E.M.) rise in the plasma histamine concentration, from 296±80 pg per milliliter before challenge to 1055±356 after challenge (P<0.001). Rises in plasma histamine that were seen after these positive oral food challenges implicate mast-cell or basophil mediators in the pathogenesis of food allergy, including cutaneous changes in patients with atopic dermatitis.
