RT Journal Article SR Electronic T1 Acute kidney injury secondary to severe delayed haemolysis in intravenous artesunate use for severe malaria JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e237501 DO 10.1136/bcr-2020-237501 VO 14 IS 1 A1 Leong, Kai Wen A1 Singh, Kasha P A1 Leder, Karin A1 Tong, Steven Y C YR 2021 UL http://casereports.bmj.com/content/14/1/e237501.abstract AB The use of artemisinin derivatives has been recommended by the WHO guidelines in malaria treatment largely due to its rapid parasite clearance and safety profile. This case report details the development of delayed haemolysis and subsequent severe acute kidney injury (AKI) 13 days after commencing intravenous artesunate treatment for malaria in an Australian returned traveller. Delayed haemolysis may be an under-recognised complication following artesunate use and if severe, can be complicated by AKI. Therefore, close patient follow-up following treatment is required to ensure prompt recognition of this phenomenon.
