食物过敏反应可见于婴儿,并常伴随其它特应性表现,这种反应需有一定比例的食物抗原与IgE抗体相接触后才能发生;若发生在与有关食品接触前,有人认为系产前致敏或产后疏忽进食或皮肤试验所致敏。近年虽有报道婴儿初次进食牛乳或蛋类而发生直接过敏反应者,然尚乏满意解释。故作者报道8例研究及随访结果,并对有关机理进行了探讨。 Food allergies can be seen in infants and are often accompanied by other atopic manifestations that require a certain percentage of food antigens to come into contact with IgE antibodies; if it occurs prior to contact with the food concerned, it is considered prenatal to Sensitive or postpartum negligent eating or skin test sensitization. In recent years, although there are reports of infant first intake of milk or eggs and direct allergic reactions occur, but still not satisfied with the explanation. Therefore, the authors report 8 cases of research and follow-up results, and the relevant mechanisms were discussed.
