Background: In the six Southeast Asian countries that make up the Greater Mekong Subregion, has developed resistance to derivatives of artemisinin, the main component of first-line treatments for malaria. Clinical resistance to artemisinin monotherapy in other global regions, including Africa, would be problematic.
Methods: In this longitudinal study conducted in Northern Uganda, we treated patients who had infection with intravenous artesunate (a water-soluble artemisinin derivative) and estimated the parasite clearance half-life.
In Uganda, artemether-lumefantrine was introduced as an artemisinin-based combination therapy (ACT) for malaria in 2006. We have previously reported a moderate decrease in ex vivo efficacy of lumefantrine in Northern Uganda, where we also detected ex vivo artemisinin-resistant Plasmodium falciparum. Therefore, it is necessary to search for candidate partner alternatives for ACT.
