Abstract
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.
