Efficacious antimalarial medicines are critical to malaria control and elimination. Continuous monitoring of their efficacy is needed to inform treatment policies in malaria-endemic countries, and to ensure early detection of, and response to, drug resistance.
Pour combattre et éliminer le paludisme, il est essentiel de disposer de médicaments antipaludiques efficaces. Un suivi régulier de l’efficacité des médicaments s’impose pour orienter les politiques de traitement dans les pays d’endémie palustre et assurer la détection précoce de la ph...armacorésistance et une intervention rapide.

WHO recommends artemisinin-based combination therapies for treating uncomplicated malaria, alongside studies to monitor treatment effectiveness. Given the threat of antimalarial resistance, including partial resistance in several African countries, molecular tools are vital for tracking resistance. ...In 2015, WHO launched the External Quality Assessment scheme for nucleic acid amplification testing to ensure reliable lab results. Coordinated by WHO and operated by the United Kingdom National External Quality Assessment Service for Parasitology, the scheme provides quality-controlled specimens and reports to help improve testing accuracy. Experts recently discussed expanding the scheme to include antimalarial resistance markers.

Effective malaria case management requires quick access to diagnostics and antimalarial treatments to reduce illness and death. Artemisinin-based combination therapy (ACT) has been essential to malaria treatment since 2001, as it combines artemisinin for rapid parasite reduction with a partner drug ...to ensure complete cure. However, resistance to antimalarial drugs, where parasites survive standard doses, threatens malaria control.

The Strategy to respond to antimalarial drug resistance in Africa is a technical and advocacy document, grounded in the best available evidence to date and aimed at minimizing the threat and impact of antimalarial drug resistance of Plasmodium falciparum parasites in Africa. Its objectives are to: i...) improve the detection of resistance to ensure a timely response; ii) delay the emergence of resistance to artemisinin and artemisinin-based combination therapy (ACT) partner drugs; and iii) limit the selection and spread of resistant parasites where resistance has been confirmed.

La Stratégie de riposte face à la résistance aux antipaludiques en Afrique est un document technique de sensibilisation qui se fonde sur les bases factuelles les plus solides dont on dispose et vise à réduire au maximum la menace et l’impact de la résistance aux antipaludiques de Plasmodium ...falciparum en Afrique. Elle a pour objectifs i) d’améliorer la détection de la résistance et d’assurer une riposte en temps utile ; ii) de retarder l’émergence de la résistance à l’artémisinine et aux médicaments associés utilisés dans les combinaisons thérapeutiques à base d’artémisinine (CTA) ; et iii) de freiner la sélection et la propagation des parasites résistants là où une pharmacorésistance est confirmée. Si la Stratégie cible l’Afrique, il convient de noter que la
menace de la résistance aux antipaludiques concerne tous les pays d’endémie palustre et que les interventions proposées dans le présent document sont applicables dans d’autres régions géographiques à condition d’être adaptées aux spécificités locales.

Antimalarial drug resistance has emerged as a threat to global malaria control efforts, particularly in the Greater Mekong subregion. Drawing on data collected through more than 1000 therapeutic efficacy studies as well as molecular marker studies of Plasmodium falciparum drug resistance, the Report... on antimalarial drug efficacy, resistance and response: 10 years of surveillance (2010–2019) presents a decade’s worth of data on drug efficacy and surveillance, as well as recommendations to monitor and protect the efficacy of malaria treatment in the decades to come.

Infection and Drug Resistance 2020:13 4047–4060
Launch of the WHO Report on antimalarial drug efficacy, resistance and response: 10 years of surveillance (2010–2019). Key findings
The reports bring together the latest findings and conclusions about the state of resistance to artemisinins and artemisinin-based combination therapy (ACT), summarize WHO’s current policy and treatment recommendations, and highlight areas of concern.
