Plant lipid transfer proteins (LTPs) are widespread plant food allergens, highly resistant to food processing and to the gastrointestinal environment, which have been described as the most common food allergens in the Mediterranean area. LTP allergy is widely described in adults, but it represents an emerging allergen also in the pediatric population. Little is known about the real prevalence and the clinical features of this allergy in children and it still often remains underdiagnosed in these patients.

An early identification and a deeper knowledge of this allergy in childhood can avoid severe systemic reactions and improve the child's quality of life. Pediatricians should always consider the possibility of LTP involvement in cases of plant-derived food allergy.

植物脂质转移蛋白 (LTP) 是广泛存在的植物性食物过敏原，对食品加工和胃肠道环境具有高度抵抗力，已被描述为地中海地区最常见的食物过敏原。LTP 过敏在成人中被广泛描述，但它也代表了儿科人群中的一种新兴过敏原。人们对这种过敏症在儿童中的真实患病率和临床特征知之甚少，并且在这些患者中仍然经常未被诊断出来。

在儿童时期及早识别并深入了解这种过敏症，可以避免严重的全身反应，提高孩子的生活质量。儿科医生应始终考虑 LTP 参与植物源性食物过敏的可能性。
