    Is p falciparum chloroquine resistant

    Chloroquine was first discovered in the 1930s in Germany and began to be widely used as an anti-malaria post-World War II, in the late 1940s. However, resistance to the drug also rapidly emerged, with the first cases of not being cured by administration of chloroquine being reported in the 1950s.

    Phenotypic analysis showed that mutant pfcrt alleles conferred a CQR phenotype to chloroquine-sensitive P. falciparum Fig. 1A. Recombinant clones expressing pfcrt alleles from the chloroquine-resistant lines Dd2, K76I, and 7G8 all had 50% inhibitory concentration IC 50 values in the range of 100 to 150 nM. Patients receiving chloroquine plus primaquine had an equivalent or lower risk of P. vivax recurrence by day 28 compared with patients receiving chloroquine alone. Overall P. vivax was defined as chloroquine resistant for more than half of the 122 sites where efficacy could be assessed. Malaria caused by Plasmodium falciparum is a severe infectious disease with high mortality and morbidity rates worldwide. Chloroquine CQ is a widely used antimalarial agent, but the emergence and spread of CQ-resistant parasites is a growing

    Nowadays, other drugs, and notably ones containing artemisinin-based compounds, are preferentially used to treat uncomplicated malaria and especially in areas where chloroquine resistance is known to occur. Since then, resistance has spread rapidly (since obviously it is beneficial to the parasite to be resistant, so various mutations conferring this protection have arisen multiple times in different areas in the world and also been passed on preferentially to new generations of malaria parasites), and now chloroquine resistant are found in multiple locations in south-east Asia, such as Myanmar and India, as well as from Guyana in South America.

  5. Chloroquine resistance is widespread in P. falciparum and is reported in P. vivax. Before using Chloroquine for prophylaxis, it should be ascertained whether Chloroquine is appropriate for use in the region to be visited by the traveler. Information regarding the geographic areas where resistance to Chloroquine occurs, is available at the Centers for Disease Control and Prevention gov\malaria.

    Summary Chloroquine-resistant malaria from P. falciparum is confirmed in patients from widespread areas throughout Thailand. For adequate treatment of patients and for the successful pursuit of malaria eradication in this area, there is an urgent need for new effective antimalarial drugs.

Recent studies have associated the reduced chloroquine accumulation observed in the parasite vacuole of resistant strains 12 with point mutations in the gene encoding for the P. falciparum chloroquine resistance transporter PfCRT protein for a review see 14, 15.
