摘　　要：目的通过皮肤点刺试验(skin prick test,SPT)和开放式食物激发试验(open oral food challenge,OFC)验证沙葱是一种能够诱发过敏性鼻炎或哮喘的新型过敏原。方法对我科收治的3例沙葱诱发过敏性哮喘患者(实验组)的临床资料进行回顾分析,同时选择3例无过敏病史的健康成人作为对照组,进行SPT和OFC。结果全部受试者的SPT和OFC结果均呈阳性;OFC显示食入沙葱后10 min出现皮肤瘙痒、喘憋症状或过敏性鼻炎症状,一秒用力呼气容积降低20%以上。结论沙葱是一种新发现的食物过敏原,在接触或食入后可能会诱发严重的食物过敏反应。Objective To investigate whether the Allium mongolicum is a novel allergen causing allergic rhinitis or allergic asthma with the skin prick test（SPT）and open oral food challenge（OFC）.
