He had had coryzal symptoms 2\u2009weeks prior to admission. Medical history included obstructive sleep apnoea and hypertension. His initial blood tests showed a mild hyperbilirubinaemia and acute kidney injury stage 1. Chest X-ray and CT pulmonary angiogram were negative for features suggestive of COVID-19. He later developed a drop in haemoglobin and repeat bloods showed markedly raised lactate dehydrogenase and positive direct antiglobulin test. These results were felt to be consistent with a haemolytic anaemia. A nasopharyngeal swab came back positive for COVID-19. We suspect the cause of his symptoms was an autoimmune haemolytic anaemia secondary to COVID-19 which has recently been described in European cohorts.<\/jats:p>","DOI":"10.1136\/bcr-2020-238118","type":"journal-article","created":{"date-parts":[[2020,12,10]],"date-time":"2020-12-10T14:22:00Z","timestamp":1607610120000},"page":"e238118","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":28,"title":["Haemolytic anaemia: a consequence of COVID-19"],"prefix":"10.1136","volume":"13","author":[{"given":"Memoona","family":"Jawed","sequence":"first","affiliation":[{"name":"Queen\u2019s Medical Centre, Nottingham University Hospital NHS Trust, Nottingham, UK"},{"name":"Acute Medicine, Queen\u2019s Medical Centre, Nottingham University Hospital NHS Trust, Nottingham, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth","family":"Hart","sequence":"additional","affiliation":[{"name":"Acute Medicine, Nottingham University Hospitals NHS Trust, Nottingham, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Malik","family":"Saeed","sequence":"additional","affiliation":[{"name":"Haematology, Nottingham University Hospitals NHS Trust, Nottingham, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,12,10]]},"reference":[{"key":"2025082703592654000_13.12.e238118.1","unstructured":"WHO .
