Only few drugs for uncomplicated Plasmodium falciparum malaria are available in children. Atovaquone-proguanil is a recent antimalarial drug licensed in France for the uncomplicated P. falciparum malaria in adults. Few paediatric studies have evaluated atovaquone-proguanil in children for uncomplicated malaria in endemic area, but no study have evaluated this treatment for imported malaria.
Objective: To evaluate treatment by atovaquone-proguanil for uncomplicated and imported P. falciparum malaria in children.
Methods: We retrospectively evaluated the tolerance and the efficacy of atovaquone-proguanil in the children admitted in Robert-Debré Hospital (Paris) for a P. falciparum malaria. From January 2004 to December 2005, 48 children with a median age of 7,5 years (IQR 4-11) were treated with atovaquone-proguanil for a uncomplicated P. falciparum malaria, except for 5 children who had an isolated hyperparasitemia greater or equal to 5%.
Results: Atovaquone-proguanil was stopped for 3/48 children because of vomiting. Fever resolved in all the children between Day 3 and 7, following the beginning of the treatment. One child, with a favourable outcome, had a positive parasitemia at Day 4 equal to the initial parasitemia (0,1%). No late therapeutic failure was observed among the 24 children evaluated up to one month after starting treatment.
Conclusion: Atovaquone-proguanil is an efficient and well-tolerated antimalarial treatment for uncomplicated P. falciparum malaria in children. The risk of vomiting should lead to a systematic initial hospitalisation of children treated with atovaquone-proguanil.
