Anaphylaxis symptoms range from mild, self-limiting local reactions to life-threatening anaphylaxis. All anaphylaxis guidelines emphasize early recognition and the need for prompt intramuscular adrenaline injection as the first-line treatment [3]. However, adrenaline for anaphylaxis is underused by patients, families and even by health professionals. In the European anaphylaxis registry, 27% of patients treated by a health professional received adrenaline [4].","PeriodicalId":10148,"journal":{"name":"Clinical & Experimental Allergy","volume":"29 1","pages":"117 - 120"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80791342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In one protocol, sensitized pigs were challenged by gavage with a single dose of HEWP. Clinical signs were monitored for 24 hours, and then, gastrointestinal (GI) tissues were collected for histological examination.
