Plain-language summary
In Nigeria, malaria is the commonest reason for outpatient clinic attendance in childhood and is responsible for about 20% of childhood deaths. The emergence of strains of P. falciparum resistant to chloroquine and sulfadoxine-pyrimethamine led to severe worsening of morbidity and mortality from malaria. As a result of resistance to previously used monotherapy, the World Health Organization (WHO) in 2001, recommended that malaria-endemic countries experiencing drug-resistant malaria infection adopt combination therapy. Artemisinin-based combination therapy (ACT) is preferred to the non-ACT combination. In this randomized open-label clinical trial, the safety and efficacy of pyronaridine-artesunate and artemether-lumefantrine in the treatment of malaria among children aged 3 to 144 months who have microscopically confirmed symptomatic Plasmodium falciparum malaria were compared. The study was carried out at the Oni Memorial Children's Hospital, Ring Road Ibadan. One hundred and seventy-two children between 3 and 120 months who meet the inclusion criteria will be enrolled after obtaining written or witnessed signed informed consent from the parents or guardian. A detailed history and physical examination were carried out on each enrollee. Finger prick blood samples were taken from each enrolee for thick blood smear for malaria parasite, haematocrit, and blood spots on filter paper. Five millilitres of venous blood will be taken from an arm vein for baseline liver function tests, creatinine, and random blood glucose on days 0, 3, 7 and 28. Enrollees were randomized into one of two groups. Group one received pyronaridine-artesunate while group two received artemether-lumefantrine at standard doses. Enrollees were seen daily from days 0-3, and on days 7, 14, 21 and 28. Study drugs were administered supervised at standard dosage on days 0, 1, and 2. History taking, physical examination and blood smears were done at each contact time. Special attention will be paid to adverse effects. Parasite clearance time, fever clearance time and cure rates were compared between the two groups.
