    History of chloroquine resistance


    Rapid diagnostic assays for Pf CRT mutations are already employed as surveillance tools for drug resistance. Here, we review recent field studies that support the central role of Pf CRT mutations in chloroquine resistance.

    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. Development of Chloroquine Resistance in Plasmodium falciparum. Drug resistance is the ability of a parasite to survive despite the presence of a drug that is meant to kill it in toxic levels. Resistance developed by most parasites that were initially sensitive to drugs mostly result from mutations in the genes responsive to the drug. Sep 15, 2001 The fact that chloroquine resistance took many years to develop in a limited number of foci contrasts with observations that resistance to another widely used antimalarial, pyrimethamine, arose rapidly on many independent occasions.

    Recognition of the value of chloroquine was delayed, and it was not brought forward until it was reevaluated in the United States and designated the drug of choice against malaria near the end of World War II [3]. These studies suggest chloroquine resistance arose in ⩾4 distinct geographic foci and substantiate an important role of immunity in the outcomes of resistant infections after chloroquine treatment. Investigation of the resistance mechanisms and of the role of immunity in therapeutic outcomes will support new approaches to drugs that can take the place of chloroquine or augment its efficiency Early in the 20th century, intense demands for an effective quinine substitute launched the discovery and evaluation of a series of organic compounds (beginning with methylene blue), which led to pamaquine and quinacrine after World War I and ultimately produced chloroquine in 1934 [1, 2].

    Compare Malarone vs Plaquenil - Plaquenil hydroxychloroquine is an effective medication for autoimmune conditions and malaria that comes with less side effects than other DMARDs. Plaquenil hydroxychloroquine has been shown to improve physical function in up to 80% of patients with rheumatoid arthritis.
