On arrival to the emergency department following initial resuscitation by ambulance staff, he was admitted to the intensive care unit with a presumptive diagnosis of gastroenteritis. This diagnosis was later revised following the availability of tryptase levels and clarification of his presenting circumstances, which established a clear temporal relationship between his anaphylactoid symptoms and the oral ingestion of <jats:italic>Chlorella vulgaris<\/jats:italic> supplements. While there are a few case studies describing allergic\/anaphylactic reactions to several other species of <jats:italic>Chlorella<\/jats:italic>, this appears to be the first reported case of anaphylaxis to <jats:italic>C. vulgaris<\/jats:italic>.<\/jats:p>","DOI":"10.1136\/bcr-2020-237054","type":"journal-article","created":{"date-parts":[[2020,11,2]],"date-time":"2020-11-02T16:05:49Z","timestamp":1604333149000},"page":"e237054","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":9,"title":["Anaphylaxis following enteral exposure to <i>Chlorella vulgaris<\/i>"],"prefix":"10.1136","volume":"13","author":[{"given":"Joshua Haron","family":"Abasszade","sequence":"first","affiliation":[{"name":"General Medicine, Northern Health, Epping, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Palaniraj","family":"Rama Raj","sequence":"additional","affiliation":[{"name":"General Medicine, Northern Health, Epping, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alistair John","family":"Tinson","sequence":"additional","affiliation":[{"name":"General Medicine, Northern Health, Epping, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2020,11,2]]},"reference":[{"key":"2025082801505063000_13.11.e237054.1","unstructured":"Ramsey A , Mustafa SS .
