Changing Antimalarial Drug Resistance Patterns Identified by Surveillance at Three Sites in Uganda.
We assessed Plasmodium falciparum drug resistance markers in parasites collected in 2012, 2013, and 2015 at 3 sites in Uganda. The prevalence and frequency of parasites with mutations in putative transporters previously associated with resistance to aminoquinolines, but increased sensitivity to lumefantrine (pfcrt 76T; pfmdr1 86Y and 1246Y), decreased markedly at all sites. Antifolate resistanc...
متن کاملIn vitro antimalarial susceptibility and molecular markers of drug resistance in Franceville, Gabon
BACKGROUND Malaria remains a major public health problem, due largely to emergence and widespread P. falciparum drug resistance. WHO recommends artemisinine combination based therapy (ACT) to overcome P. falciparum drug resistance, but reports of declining ACT efficacy have been published. A thorough understanding of the molecular bases of P. falciparum resistance to existing drugs is therefore...
متن کاملPrevalence of Plasmodium falciparum Molecular Markers of Antimalarial Drug Resistance in a Residual Malaria Focus Area in Sabah, Malaysia
Chloroquine (CQ) and fansidar (sulphadoxine-pyrimethamine, SP) were widely used for treatment of Plasmodium falciparum for several decades in Malaysia prior to the introduction of Artemisinin-based Combination Therapy (ACT) in 2008. Our previous study in Kalabakan, located in south-east coast of Sabah showed a high prevalence of resistance to CQ and SP, suggesting the use of the treatment may n...
متن کاملSelection of parasites with diminished drug susceptibility by amodiaquine-containing antimalarial regimens in Uganda.
BACKGROUND Amodiaquine (AQ) is paired with artesunate (AS) or sulfadoxine-pyrimethamine (SP) in recommended antimalarial regimens. It is unclear how readily AQ resistance will be selected with combination chemotherapy. METHODS We collected 61 Plasmodium falciparum samples from a cohort of Ugandan children randomized for treatment with AQ-SP, AS-AQ, or artemether-lumefantrine (AL) for uncompli...
متن کاملAntimalarial drug resistance
Antimalarial drug resistance is of great concern in the WHO South-East Asia (SEA) Region. A high degree of resistance of Plasmodium falciparum to chloroquine and sulfadoxine-pyrimethamine is prevalent in this Region. Multidrug resistance is prevalent in some parts of the Greater Mekong Sub-region. Artemisinin and its derivatives in combination with other effective partner drugs, which showed fa...
