    Plasmodium falciparum resistance to chloroquine


    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.

    Key words chloroquine, resistance, genetic markers, Pfcrt, Pfmdr, mutations. Introduction The problem of chloroquine resistance in Plasmodium falciparum infections has complicated the management of malaria in countries where chloroquine is the first line antimalarial drug. The effect is felt mostly in the malaria endemic countries Drug-resistant P. falciparum. Chloroquine-resistant P. falciparum first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted. The emergence and spread of drug-resistant Plasmodium falciparum impedes global efforts to control and eliminate malaria. For decades, treatment of malaria has relied on chloroquine CQ, a safe.

    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.

  2. Chloroquine-resistant malaria is now widespread in africa
  3. Chloroquine resistance in the human malaria parasite, Plasmodium falciparum, arises from decreased accumulation of the drug in the `digestive vacuole' of the parasite, an acidic compartment in which chloroquine exerts its primary toxic effect. It has been proposed that changes in the pH of the digestive vacuole might underlie the decreased accumulation of chloroquine by chloroquine-resistant.

    Plasmodium falciparum chloroquine resistance transporter is a H+-coupled polyspecific nutrient and drug exporter Narinobu Jugea,b, Sawako Moriyamac, Takaaki Miyajia, Mamiyo Kawakamic, Haruka Iwai c, Tomoya Fukui, Background Mutations in the chloroquine resistance transporter PfCRT change the susceptibility of Plasmodium falciparum to diverse antimalarial drugs. Results In addition to chloroquine, PfCRT transports quinine, quinidine, and verapamil, which bind to distinct but antagonistically interacting sites. Since the discovery of Plasmodium falciparum chloroquine CQ resistance transporter PfCRT and its role as the primary genetic determinant of chloroquine resistance CQR in P. falciparum, 53 distinct isoforms of this 424 amino acid protein have been found to be expressed in parasite isolates from around the globe 1–4.
