    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.

    Now, chloroquine resistant forms of P. vivax are found in multiple locations in south-east Asia, such as Myanmar and India, as well as from Guyana in South America. 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 the first documentation of P. falciparum chloroquine resistance in the 1950s, resistant strains have appeared throughout East and West Africa, Southeast Asia, and South America. The effectiveness of chloroquine against P. falciparum has declined as resistant strains of the parasite evolved. P. falciparum malaria is almost always choloroquine resistant, although cases acquired in Haiti are a notable exception. Extensive reports of chloroquine treatment failures with P. vivax have been reported from Papua New Guinea and Indonesia along with sporadic reports from Brazil, Myanmar, India, Guyana, and Colombia.

    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.

  3. However, the efficiency of chloroquine has been severely impacted by the recent development of chloroquine resistant plasmodium falciparum parasites. The development of chloroquine resistance by malaria parasites is increasing at an alarming rate especially in the tropical countries where it is used extensively as an antimalarial drug 2.

    Chloroquine sensitive parasites CQS accumulate much more chloroquine in the DV than chloroquine resistant strains CQR. 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. 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. In most parts of the world, P. falciparum is resistant to chloroquine, and the recommended treatment is artemisinin bases combinations. Primaquine should be used in P. vivax and P. ovale malaria for eradicating the persisting liver forms and in P. falciparum malaria to destroy the gametocytes, so as to prevent the spread of infection.
