    Chloroquine resistant plasmodium falciparum treatment


    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.

    Chloroquine CQ was the cornerstone of anti-malarial treatment in Africa for almost 50 years, but has been widely withdrawn due to the emergence and spread of resistance. Recent reports have suggested that CQ-susceptibility may return following the cessation of CQ usage. Here, we monitor CQ sensitivity and determine the prevalence of genetic polymorphisms in the CQ resistance transporter. Non-falciparum malaria treatment Non-falciparum malaria is usually caused by Plasmodium vivax and less commonly by P. ovale and P. malariae. P. knowlesi is also present in the Asia-Pacific region. Chloroquine is the drug of choice for the treatment of non-falciparum malaria but chloroquine-resistant P. vivax has been reported in the Indonesian archipelago, the Malay Peninsula, including. This treatment summary topic describes Malaria, treatment. Falciparum malaria treatment Falciparum malaria malignant malaria is caused by Plasmodium most parts of the world P. falciparum is now resistant to chloroquine which should not therefore be given for treatment.

    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.

  5. Plasmodium falciparum chloroquine resistance is a major cause of worldwide increases in malaria mortality and morbidity. Recent laboratory and clinical studies have associated chloroquine resistance with point mutations in the gene pfcrt. However, direct proof of a causal relationship has remained elusive and most models have posited a multigenic basis of resistance.

    We obtained 78 human blood samples from areas in Haiti with high transmission of malaria and found no drug resistance–associated mutations in Plasmodium falciparum chloroquine resistance transporter and Kelch 13 genes. We recommend maintaining chloroquine as the first-line drug for malaria in Haiti. Artemisinin-based therapy can be used as alternative therapy. Abstract. Background. Due to development of multidrug-resistant Plasmodium falciparum new antimalarial therapies are needed. In Guinea-Bissau, routinely used triple standard-dose chloroquine remained effective for decades despite the existence of “chloroquine-resistant” P. falciparum. Since Moore And Lanier's 1 report of two patients with chloroquine-resistant Plasmodium falciparum infections acquired in the Magdalena Valley of Columbia in 1961, a fear has existed among malariologists that large-scale outbreaks of resistant malignant tertian malaria might develop. This fear was increased considerably by the discovery of strains of chloroquine-resistant P. falciparum in.
