    Chloroquine resistance vivax


    Rapid diagnostic assays for Pf CRT mutations are already employed as surveillance tools for drug resistance. Here, we review recent field studies that support the central role of Pf CRT mutations in chloroquine resistance.

    Usual Adult Dose for Malaria Prophylaxis. 500 mg chloroquine phosphate 300 mg base orally on the same day each week Comments-If possible, suppressive therapy should start 2 weeks prior to exposure; if unable to start 2 weeks before exposure, an initial loading dose of 1 g chloroquine phosphate 600 mg base may be taken orally in 2 divided doses, 6 hours apart. Emerging resistance to chloroquine CQ by Plasmodium vivax threatens the health of the hundreds of millions of people routinely exposed to the risk of infection with this organism. CQ has been the first-line therapy for vivax malaria since 1946 32, 115. Sep 15, 2001 Although the action of chloroquine is probably similar in P. vivax and P. falciparum it appears that the development of chloroquine resistance involved different molecular events in these 2 species. The P. vivax homologue of the PfCRT transporter was identified recently and was found to lack mutations that could be associated with chloroquine treatment failures in humans or monkeys 72.

    Recognition of the value of chloroquine was delayed, and it was not brought forward until it was reevaluated in the United States and designated the drug of choice against malaria near the end of World War II [3]. These studies suggest chloroquine resistance arose in ⩾4 distinct geographic foci and substantiate an important role of immunity in the outcomes of resistant infections after chloroquine treatment. Investigation of the resistance mechanisms and of the role of immunity in therapeutic outcomes will support new approaches to drugs that can take the place of chloroquine or augment its efficiency Early in the 20th century, intense demands for an effective quinine substitute launched the discovery and evaluation of a series of organic compounds (beginning with methylene blue), which led to pamaquine and quinacrine after World War I and ultimately produced chloroquine in 1934 [1, 2].

    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. Here, a cross of Plasmodium vivax malaria parasites links a chloroquine resistance CQR phenotype to a 76 kb region of chromosome 1 and greater expression of pvcrt, an ortholog of the Plasmodium. Chloroquine resistance was first reported in both South America and South East Asia in late 1950s. Since then chloroquine resistant strains have spread throughout the ranges where the conditions are favorable for the development of the parasite especially in the regions of sub-Saharan Africa 6.
