Molecular Method Optimization to Identify Plasmodium falciparum Multidrug Resistance 1 (pfmdr1) gene as a Predictor of Antimalarial Resistance [PDF]

Biology, Medicine & Natural Product Chemistry
Several approaches have been designed to control malaria, a disease with high morbidity and mortality, but they face some hurdles. Antimalarial resistance is one of the major challenges for malaria elimination, so the detection of antimalarial resistance

Correlation of molecular markers, Pfmdr1-N86Y and Pfcrt-K76T, with in vitro chloroquine resistant Plasmodium falciparum, isolated in the malaria endemic states of Assam and Arunachal Pradesh, Northeast India.

PLoS ONE, 2014
The mechanism of chloroquine (CQ) resistance in Plasmodium falciparum is not clearly understood. However, CQ resistance has been shown to be associated with point mutations in Pfcrt and Pfmdr1.

The Impact of <i>pfmdr1</i> Gene Copy Number on the Efficacy of Dihydroartemisinin-Piperaquine in Treating Malaria in West Sumba and Kupang Districts, East Nusa Tenggara, Indonesia. [PDF]

J Parasitol Res
The efficacy of antimalarial treatment, particularly artemisinin‐based combination therapy (ACT), continues to face persistent threats due to the development of drug resistance in Plasmodium falciparum. Although artemisinin derivatives remain effective, ACT regimen failure often results from decreased efficacy of the companion drug.

Polymorphism of <i>pfmdr1</i> Gene Mutation Conferring Resistance to Artemisinin-Based Combination Therapy in <i>Plasmodium falciparum</i> in Patients at Gulu Regional Referral Hospital in Northern Uganda. [PDF]

J Parasitol Res
Background Malaria is one of the most devastating infectious diseases in humans, and antimalarial drugs have been used to combat it with minimal success. Worldwide, malaria treatment is threatened by the emergence and spread of artemisinin resistance, which is associated with mutations in the PfK13 propeller domain. In Sub‐saharan Africa, data relating

Polymorphisms in Plasmodium falciparum chloroquine resistance transporter and multidrug resistance 1 genes: parasite risk factors that affect treatment outcomes for P. falciparum malaria after artemether-lumefantrine and artesunate-amodiaquine. [PDF]

, 2014
Adequate clinical and parasitologic cure by artemisinin combination therapies relies on the artemisinin component and the partner drug. Polymorphisms in the Plasmodium falciparum chloroquine resistance transporter (pfcrt) and P.

Molecular Markers of Antimalarial Drug Resistance in Plasmodium falciparum From Kumasi, Ghana, 2023. [PDF]

Trop Med Int Health
ABSTRACT Objectives Artemisinin partial resistance has emerged in East Africa and is feared to spread across the continent, potentially compromising artemisinin‐based combination treatment. Molecular markers can serve as early warning signals for the development of specific drug resistance.
