“花生贴片”将能拯救生命

根据美国过敏、哮喘与免疫学协会( American Academy of Allergy, Asthma & Immunology)的数据显示, 花生是引起儿童食物过敏的最重要过敏原之一,不幸的是,花生过敏还会发生一种具有潜在致命性的反应。花生过敏是食物过敏死亡的罪魁祸首。而现在,生物技术公司DBV Technologies成功研发一款花生过敏贴片Viaskin Peanut,能够逐步训练人体免疫系统对花生产生耐受性。

美国食品过敏研究联盟已经利用这种贴片进行一项研究,这项研究由美国国家过敏和传染病研究所资助。 截至目前,已有75名4-25岁的花生过敏志愿者在使用这种贴片。 在为期一年的临床试验中,研究证实高剂量(250mg)或低剂量(100mg)的Viaskin Peanut贴片改善了志愿者的花生过敏。

试验结果证实,近一半高剂量组及低剂量组的志愿者摄取的花生蛋白比之前增加了10倍以上,同时并未产生任何过敏反应——4-11岁的儿童表现尤为突出。

值得注意的是,这款产品尚未获得美国食品和药物管理局(FDA)的正式批准。

这项研究成果近日发表在《过敏与临床免疫学杂志》上。
