    Plasmodium falciparum chloroquine resistance usmle


    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    We obtained 78 human blood samples from areas in Haiti with high transmission of malaria and found no drug resistance–associated mutations in Plasmodium falciparum chloroquine resistance transporter and Kelch 13 genes. We recommend maintaining chloroquine as the first-line drug for malaria in Haiti. Artemisinin-based therapy can be used as alternative therapy. Widespread use of antimalarial agents can profoundly influence the evolution of the human malaria parasite Plasmodium falciparum. Recent selective sweeps for drug-resistant genotypes may have. Used in areas with high rates of chloroquine resistance; atovaquone/proguanil or artemether-lumefantrine. used in areas with high rates of chloroquine resistance. first-line treatment for P. falciparum resistant to chloroquine; primaquine. used to kill latent hypnozoites in Plasmodium vivax and Plasmodium ovale infection ; intravenous quinidine.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

    To determine whether withdrawal of chloroquine can lead to the reemergence of chloroquine sensitivity, the prevalence of the pfcrt 76T molecular marker for chloroquine-resistant Plasmodium falciparum malaria was retrospectively measured in Blantyre, Malawi. Despite its strategic location and importance, malaria epidemiology and molecular status of chloroquine resistance had not been well documented, and since chloroquine CQ, as the first-line treatment in Plasmodium falciparum infection was discontinued since 2008, it was expected that CQ-sensitive haplotype would be more abundant. Chloroquine-resistant Plasmodium falciparum accumulate significantly less chloroquine than susceptible parasites, and this is thought to be the basis of their resistance. However, the reason for the lower accumulation of chloroquine was unknown. The resistant parasite has now been found to release chloroquine 40 to 50 times more rapidly than the susceptible parasite, although their initial.
