    Chloroquine resistance in plasmodium falciparum


    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.

    Chloroquine mechanism of drug action and resistance in Plasmodium falciparum. Slater AF1. Author information 1Picower Institute for Medical Research, Manhasset, NY 11030. Quinoline-containing drugs such as chloroquine and quinine have had a long and successful history in antimalarial chemotherapy. Chloroquine-resistant Plasmodium falciparum accumulate significantly less chloroquine than susceptible parasites, and this is thought to be the basis of their resistance. However, the reason for the lower accumulation of chloroquine was unknown. The resistant parasite has now been found to release chloroquine 40 to 50 times more rapidly than the susceptible parasite, although their initial. Malaria. Chloroquine has long been used in the treatment or prevention of malaria from Plasmodium vivax, P. ovale, and P. malariae, excluding the malaria parasite Plasmodium falciparum, for it started to develop widespread resistance to it. Chloroquine has been extensively used in mass drug administrations.

    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.

    The mutations in the digestive vacuole transmembrane protein Plasmodium falciparum chloroquine resistance transporter PfCRT are mainly responsible for chloroquine resistance CQR in Plasmodium. Standard triple-dose therapy with chloroquine 25 mg base/kg failed to clear asexual Plasmodium falciparum parasites from the blood of 22 of 98 patients infected in various parts of Ethiopia and evaluated in Addis Ababa, a malaria-free city. RI to RIII levels of resistance A distinct genotype designated Dd2-type profile consisting of 12 point mutations and 3 repetitive regions of the CG2 gene, a candidate gene for chloroquine resistance, has been associated with in vitro resistance in laboratory-adapted strains of Plasmodium falciparum. The DNA sequence of clinical isolates, characterized by in vitro and in vivo tests, was analyzed to evaluate whether the genotype corresponds to the phenotype in naturally occurring parasites.

    SARCOIDOSIS TREATMENT GUIDELINES Hydroxychloroquine. As a treatment for sarcoidosis, the antimalarial drug hydroxychloroquine Plaquenil® is most likely to be effective in patients with dermatologic involve-ment, joint manifestations and hypercalcemia. Due to poten-tial macular toxicity, it is recommended that patients on hydroxychloroquine have an eye examination every 6-12.
