ABSTRACT
Background:
Malaria is the primary cause of hospitalization in Ctte d'Ivoire. Early treatment is one of the strategies to control this illness. However; the spread of resistance of Plasmodium falciparum to antimalarial drugs can seriously compromise this strategy.Objectives:
The aim of this study was to assess the in vitro susceptibility of P. falciparum to monodesethylamodiaquine and aminoalcohols in Abidjan (Ctte d'Ivoire).Methods:
We assessed the in vitro susceptibility of isolates collected from patients with uncomplicated malaria by using the WHO optical microtest technique.Results:
The proportions of resistance to monodesethylamodiaquine; m?floquine and halofantrine were 12.5; 15.6and 25.9; respectively. For quinine; none of isolates showed evidence of in vitro resistance. However; two isolates (6.1) had IC 50 values above 300 nM. The IC 50 of each drug was positively and significantly correlated to that of the other three drugs; and the correlation was higher between halofantrine and mefloquine.Conclusions:
Our results showed that the in vitro chloroquine resistance reported in previous studies has been extended to other antimalarial drugs investigated in this study except for quinine. Therefore; it is necessary to implement a long-term monitoring system of antimalarial drug resistance. 15.6and 25.9; respectively.
