    Chloroquine and bacterial 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 is still the drug of choice for the treatment of uncomplicated falciparum malaria in most of sub-Saharan Africa. But the increasing number of therapeutic failures with chloroquine has led to concern about whether this drug can remain effective for long in Africa. Before deciding to change the drug policy on the first-line antimalarial treatment, the extent of true drug resistance. An ancillary role for PfMDR1 in chloroquine resistance cannot be ruled out though. A genetic cross and mapping studies between a chloroquine resistant clone and a chloroquine sensitive clone resulted in the identification of a 36 kb region on chromosome 7 associated with chloroquine resistance. Chloroquine is the generic form of the brand-name prescription medicine Aralen, which is used to prevent and treat malaria — a mosquito-borne disease caused by a parasite — and to treat.

    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].

  6. 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.

    Drug-resistant P. falciparum. Chloroquine-resistant P. falciparum first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted. This chloroquine efflux occurs at a rate 40 to 50 fold faster among resistant parasites than that in sensitive ones Mutations in pfmdr­1 & 2 and pfcrt gene have also been associated with chloroquine resistance. J Vect Borne Dis 41, September & December 2004, pp 45–53 The term “chloroquine resistance” can lead to misunderstandings when it is considered by some to refer to in vitro phenotypes, by others to refer to the ability of malaria parasites to survive chloroquine at therapeutic serum concentrations in vivo, and yet by others to refer to the outcome of a clinical episode after chloroquine therapy.

    DMARDs Disease-Modifying Antirheumatic Drugs – CreakyJoints Other DMARDs include sulfasalazine Azulfidine®, leflunomide Arava®, hydroxychloroquine. One of the side effects of leflunomide Arava, like methotrexate, is the potential for liver toxicity. Azathioprine Imuran® is indicated for rheumatoid arthritis. It is used very rarely to treat psoriatic arthritis.

Significant risk factors for retinal damage include daily doses of chloroquine phosphate more than 2.3 mg/kg of actual body weight, duration of use more than 5 years, subnormal glomerular filtration renal impairment or renal failure, use of some concomitant drug products such as tamoxifen, and concurrent macular disease.
