    Chloroquine resistant p falciparum


    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 is a 4-aminoquinoline which has marked, rapid schizontocidal activity against blood forms of P. ovale and P. malariae and against susceptible strains of P. vivax and P. falciparum. It is also gametocytocidal against P. vivax, P. ovale and P. malariae and immature P. falciparum. It is not active against intrahepatic forms. Chloroquine associated with primaquine since 2009, is the recommended first-line treatment for uncomplicated malaria. In vitro and molecular surveillance data collected during the past 2 decades suggest continued P. falciparum sensitivity to chloroquine 3, 8, 9. Plasmodium falciparum resistance to anti-malarial drugs remains a major obstacle to malaria control and elimination. The parasite has developed resistance to every anti-malarial drug introduced for wide-scale treatment. However, the spread of resistance may be reversible. Malawi was the first country to discontinue chloroquine use due to widespread resistance. Within a decade of the removal of.

    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.

    In this study we have investigated the digestive vacuole pH of a chloroquine-sensitive and a chloroquine-resistant strain of P. falciparum, using a range of dextran-linked pH-sensitive fluorescent dyes. The estimated digestive vacuole pH varied with the concentration and pKa of the dye, ranging from ∼3.7-6.5. DRUG RESISTANT MALARIA Chloroquine resistance Chloroquine is ineffective in almost all malaria endemic countries In India chloroquine resistance was first detected in 1973 in Assam. Severe in northeast and southeastern regions of India with high morbidity and mortality. It has been found that certain strains of P. falciparum have become resistant to 4-aminoquinoline compounds including chloroquine and hydroxychloroquine. Chloroquine resistance is widespread and, at present, is particularly prominent in various parts of the world including sub- Saharan Africa, Southeast Asia, the Indian subcontinent, and over large portions of South America, including the Amazon basin 1.

The following adverse reactions have been identified during post-approval use of PLAQUENIL or other 4-aminoqunoline compounds. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
