    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.

    To the Editor Plasmodium vivax is the protozoan that causes the second most common form of malaria. Some resistant strains to chloroquine CQ occur in a few places in Asia and the Indo-Pacific Region 1–4. 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. Chloroquine-resistant P vivax was first reported in 1989, almost 30 years after chloroquine-resistant P falciparum was first noted. 9,10 The absence of reliable, robust, sensitive methods for detection, mapping, and monitoring of antimalarial drug efficacy in P vivax has almost certainly contributed to the delayed recognition of this emerging problem. 11 This delay has had important public health implications.

    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].

    The first patient with chloroquine resistant vivax malaria was reported from Papua New Guinea in 1989. Since then cases have been reported from a vast geographical area spanning the continents of Asia Indonesia, Myanmar, India, Turkey 76–79, Africa Ethiopia and South America Brazil, Peru, Colombia 81–83. In response, several. Chloroquine remains the treatment of choice for vivax malaria, except in Indonesia's Irian Jaya Western New Guinea region and the geographically contiguous Papua New Guinea, where chloroquine resistance is common up to 20% resistance. Chloroquine resistance is an increasing problem in other parts of the world, such as Korea and India. 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.
