Background: Plasmodium falciparum resistance to antimalarial drugs remains to be a major threat to the control of malaria globally. After the deployment of artemisinin-based combination therapy (ACT), there have been reports of reduced sensitivity of the drug to parasite clearance. In Kenya, artemisinin-lumefantrine (AL) is the recommended first-line drug in the treatment of uncomplicated malaria. This study sought to assess the efficacy of AL after its reintroduction in Kenya, a decade later. In this study, we assessed clinical and parasitological responses of children under five years in May and November 2015 in Chulaimbo sub-County, Kisumu, Kenya.Method: Patients of ≥6 and ≤60 months of age with confirmed Plasmodium falciparum mono-infection were enrolled in the study. The patients were treated with a standard dose of AL and followed up for 28 days. During which period we monitored treatment responses and follow-up adherence.Results: Of the 90 patients enrolled, fourteen (14) were lost to follow-up, with 76 completing the study period. Seventy-five patients 75 (98.7%) cleared, parasitemia within 48 hours while one (1.3%) cleared on day 3. There was 100% clinical and parasitological parasite clearance. Conclusion: Artemisinin lumefantrine was found to be highly efficacious to plasmodium falciparum parasites in children aged ≥6 and ≤60 months. Based on this, the drug can be used to treat uncomplicated malaria in the study population. However, there is need for continued monitoring of its effectiveness in children and adults to counter the threat of resistance. |
