The purpose of the study is to determine whether the artesunate-amodiaquine combination is effective in treating uncomplicated Plasmodium falciparum malaria in children with severe acute malnutrition.

Infection with Plasmodium falciparum malaria remains a significant cause of morbidity and mortality in malnourished children. Malnutrition is known to have a modulating effect on the incidence of malaria infections, its severity and effectiveness of treatments. However, little data exists on antimalarial drug efficacy in malnourished children. Artesunate-amodiaquine combination is the first line treatment used in Médecins Sans Frontières programmes in Niger. The assumption of current efficacy of artesunate-amodiaquine is based on non malnourished children. The aim of this study is to measure the clinical and parasitological efficacy in severely malnourished children.

The study is consistent with the standard WHO protocol for monitoring antimalarial drug efficacy (WHO: Methods for surveillance of antimalarial drug efficacy. Geneva; 2009), except for one inclusion criterion. Severe acute malnutrition is an inclusion criteria, instead of being an exclusion criteria. The study will encompass a pharmacokinetic part that will provide important information on the absorption of the drug.

  • Consent of a parent or guardian who is at least 18 years of age.

Exclusion Criteria:
