  1. 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.

    Resistance to chloroquine has, however, steadily spread since the 1960s from two foci, one in South America and one in South East Asia. Throughout the 1980s, chloroquine resistance spread through Africa, the global heartland of malaria mortality and morbidity, and there are very few effective and affordable drugs to take its place. The subsequent transmission of resistant strains of falciparum to new waves of nonimmune workers, month after month, and their treatment with high but often noncurative doses of chloroquine.

    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].

  4. Chloroquine resistance was first reported in both South America and South East Asia in late 1950s. Since then chloroquine resistant strains have spread throughout the ranges where the conditions are favorable for the development of the parasite especially in the regions of sub-Saharan Africa 6.

    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 Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. At doses typically used to treat fish diseases, chloroquine is also toxic to many invertebrates, algae and bacteria. Seriously high ammonia levels 1 mg/l NH 3 are sometimes seen a few days to a week after dosing an aquarium with chloroquine. It is unknown why this is seen in some aquariums but not others.

    Sulfasalazine and Hydroxychloroquine • Versus Arthritis. Hi tere, I take sulphasalazine and hydroxychloroquine in combination with methotrexate, They sometimes give me a slightly dodgy tummy, but nothing unbearable if it gets too problematic I miss 2 or 3 doses and it soon settles again.
