“Presumptive treatment” without the benefit of laboratory confirmation should be reserved for extreme circumstances (strong clinical suspicion or severe disease in a setting where prompt laboratory diagnosis is not available).

Reading oct screening results plaquenil Foods to avoid while taking plaquenil Blood stage treatment In most endemic countries, chloroquine remains the first-line treatment for P. vivax malaria.

Artemisinin or chloroquine for blood stage Plasmodium vivax malaria in Vietnam Article PDF Available in Tropical Medicine & International Health 710858-64 November 2002 with 78 Reads Resistance to chloroquine of malaria strains is known to be associated with a parasite protein named PfCRT, the mutated form of which is able to reduce chloroquine accumulation in the digestive vacuole of the pathogen. Whether the protein mediates extrusion of the drug acting as a channel or as a carrier and which is the protonation state of its chloroquine substrate is the subject of a.

In vitro studies with Chloroquine demonstrated that it is active against the trophozoites of Entamoeba histolytica. Chloroquine enters the red blood cell by simple diffusion, inhibiting the parasite cell and digestive vacuole. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion.
