Term anaphylaxis means an immediate hypersensitivity reaction mediated by IgE that produces a clinical syndrome with systemic affection of variable severity. Its prevalence varies according to the habits of each region and of the studied population from 3.2 to 7.6 cases per 100,000 inhabitants per year. Anaphylaxis secondary to the food ingestion accounts for 30-50% of the cases. Some risk factors have been defined, among them the most important are asthma, food allergy and previous reactions to the same food. Biphasic anaphylactic reactions are those presenting a recurrence of anaphylactic symptoms, after the initial remission of them. Success of treatment is based on the early recognition of signs and symptoms and the instauration of treatment with adrenaline.
过敏反应一词是指由IgE介导的即刻超敏反应，可产生具有不同严重程度全身影响的临床综合征。其患病率因各地区和所研究人群的习惯而异，每年每10万居民中有3.2至7.6例。食物摄入继发的过敏反应占病例的30%-50%。已确定了一些危险因素，其中最重要的是哮喘、食物过敏和既往对同一食物的反应。双相过敏反应是指在最初症状缓解后，过敏症状再次出现。治疗的成功基于对体征和症状的早期识别以及肾上腺素治疗的启动。
