简要总结
Two hundred fifteen children (114 in the artemether-lumefantrine group and 101 in the artesunate-amodiaquine group) were studied. At the end of 28 days, 111 and 94 children in the artemether-lumefantrine and artesunate-amodiaquine groups, respectively, achieved the desired endpoints. Cure rates of greater than 99% were observed with both treatments. All but one patient were free of parasites at day 3. None of the 215 day 0 samples carried a K13 mutation known to be associated with artemisinin partial resistance. Most samples carried crt wild type (79% to 89%). For the mdr-1 gene, the single 184F mutation, which has no clear impact on the efficacy of artemisinin-based combination therapies, was very common. Furthermore, the dhfr/dhps quintuple responsible for sulfadoxine/pyrimethamine treatment failures was not detected. No adverse events were observed in treated patients. The results of this study support the continued use of first- and second-line therapies for uncomplicated falciparum malaria and sulfadoxine/pyrimethamine for intermittent preventive treatment during pregnancy.
