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 sensitivities of Plasmodium falciparum to different antimalarial drugs in Uganda.
The control of malaria is challenged by resistance of Plasmodium falciparum to multiple drugs. New combination regimens are now advocated for the treatment of uncomplicated falciparum malaria, but the extent of resistance to newer agents is incompletely understood. We measured the in vitro sensitivity of P. falciparum parasites cultured from children enrolled in a drug efficacy trial in Kampala...
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...
متن کاملAntimalarial drug resistance.
Malaria, the most prevalent and most pernicious parasitic disease of humans, is estimated to kill between one and two million people, mainly children, each year. Resistance has emerged to all classes of antimalarial drugs except the artemisinins and is responsible for a recent increase in malaria-related mortality, particularly in Africa. The de novo emergence of resistance can be prevented by ...
