大约20%的人群患偏头痛,女性比男性常见.食物可能是偏头痛的原因.因此作者前瞻性研究了一组神经科门诊严重偏头痛患者的食物变态反应性.通过放射变态反应性吸收剂试验(RAST)评价对食物特异性IgE试验的价值.发现这些患者可分为2组:大多数RAST阳性者对排除食物具有良好的反应,而一小部份RAST阴性者对排除食物无反应.作者的结论是:食物过敏性反应对偏头痛起了作用,RAST有助于明确引起偏头痛的食物.研究方案:第一阶段,对47例患者进行了前瞻性研究了食物过敏性,除因各种原因14例未能统计
About 20% of the population has migraine headaches, and women are more common than men.Food may be the cause of migraine.So the authors prospectively studied the food allergy in a group of neurological outpatients with severe migraines.With radiation-allergic absorbent Trial (RAST) evaluates the value of the food-specific IgE test and found that these patients could be divided into two groups: the majority of RAST-positive patients had a good response to the exclusion of food while the small number of RAST-negatives did not respond to the exclusion of food. The authors conclude that food allergic reactions play a role in migraine and that RAST helps to pinpoint the foods that cause migraines Research Protocol: Phase I, a prospective study of 47 patients with food allergy, except for 14 cases for various reasons failed to statistics
