    In regards to malaria what is chloroquine resistance


    Protecting the efficacy of artemisinin-based combination therapies (ACTs) as the current first- and second-line treatment for Antimalarial drug efficacy is assessed through therapeutic efficacy studies (TES). TES are conducted in a controlled environment in which drug administration is supervised, the results of microscopic examinations of blood films are validated, and the origin and quality of the drugs are verified.

    The key mutation appears to be K76T since no chloroquine resistant isolate carries the wild type lysine at place 76. It should be noted that often numerous other mutations are famous in chloroquine resistant malaria, however only the K76T amino acid switch is seen persistently in the chloroquine resistant malaria. Although chloroquine-resistant P. falciparum predominates in Africa, it is found in combination with chloroquine-sensitive P. vivax malaria in South America and Asia. Resistance of P. vivax to chloroquine has been confirmed only in Papua New Guinea and Indonesia. For destinations where any chloroquine-resistant malaria is present, in addition. The clinical usefulness of chloroquine, and in some recent cases of quinine as well, has been much reduced by the evolution and spread of chloroquine resistant malaria parasites. The mechanism of resistance involves a reduced accumulation of the drug, although again the mechanism involved is controversial.

    Studies at regular intervals at the same sites allow for the early detection of resistance. TES are prospective evaluations of patients’ clinical and parasitological responses to directly observed treatment for uncomplicated malaria.

  7. Feb 29, 2020 Hydroxychloroquine and chloroquine are medications traditionally prescribed to prevent or treat malaria infections. In certain countries and parts of the world where malaria is still present, a person can easily catch malaria from a seemingly insignificant mosquito bite.

    Chloroquine is a 9-aminoquinoline known since 1934. Apart from its well-known antimalarial effects, the drug has interesting biochemical properties that might be applied against some viral infections. Chloroquine exerts direct antiviral effects, inhibiting pH-dependent steps of the replication of several viruses including members of the flaviviruses, retroviruses, and coronaviruses. Its best. Chloroquine resistance has emerged independently less than ten times in the past 50 years and the most of the chloroquine resistance targets are localized in the acid food vacuole of the malaria. 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.

    Combination therapy with methotrexate and hydroxychloroquine. OBJECTIVE To examine the bioavailability of methotrexate MTX in the presence of hydroxychloroquine HCQ, and vice versa, to determine a possible pharmacokinetic explanation for the observation that combination treatment of rheumatoid arthritis with MTX and HCQ has been shown, clinically, to be more potent than MTX used alone.
