This document provides an overview of the use of rectal artesunate (RAS) as a pre-referral treatment for severe P. falciparum malaria, as reviewed by the World Health Organization's Malaria Policy Advisory Group. It discusses the findings from a large-scale study conducted in three African countries, highlighting challenges in real-life application such as incorrect dosing and incomplete treatment adherence. The report emphasizes the importance of adhering to WHO guidelines to prevent the spread of antimalarial resistance. It advises countries to review their deployment of RAS and await further WHO guidance for safe implementation. The intended audience includes health policymakers and practitioners involved in malaria treatment and prevention.

"Artemisinin-based combination treatments (ACTs) are seen as an important tool in the global effort to roll back malaria. With rapidly increasing parasite resistance to chloroquine in many parts of the world, there is greater international recognition of the need for both a different antimalarial and a coordinated malaria treatment strategy to ensure that resistance does not needlessly cut short the useful therapeutic life of any successor drug to chloroquine. The effectiveness of antimalarial drugs is a global public good, of particular value in malarious regions that also are among the most economically impoverished parts of the world. Inappropriate drug use in neighboring countries reduces the incentive of any given country to deploy drug regimens that may be rapidly undermined by resistance originating outside their borders. Therefore, a case can be made for globally coordinated action to protect the effectiveness of these valuable drugs. Translating this case to one for a global subsidy is not straightforward. On the one hand, in the absence of such a subsidy to ensure that ACTs are comparably priced to monotherapies, increasing monotherapy of artemisinin and other antimalarials that would be used along with artemisinin in ACT will hasten the demise of this drug. On the other hand, a global subsidy would greatly increase the use and potential misuse of ACTs and could result in resistance emerging at a more rapid rate. This study finds that a subsidy to ACTs is likely to slow the rate of emergence of resistance to artemisinin and partner drugs, even if such a subsidy were to increase the use of ACTs significantly. This conclusion is robust to alternative assumptions regarding the responsiveness of demand to the lower price for ACTs and a wide range of epidemiological and economic parameters. However, the simulation results show that a subsidy for two or more ACT combinations is likely to be much more cost-effective than a subsidy to a single ACT. The only consideration is that the drugs used as partners to artemisinin be unrelated to each other and to artemisinin in mechanism of action and in genetic bases of resistance, so that a single mutation cannot encode resistance to both components. Such a subsidy program for ACTs, administered globally, that reduces reliance on any single combination, and discourages monotherapy, not only of artemisinin but of any effective antimalarial that could potentially be used as partner drug with artemisinin, is likely to be effective (and cost-effective) both in buying time for ACTs and in saving lives "--World Bank web site.

Ce livre retrace l’histoire passionnante des travaux précurseurs qui ont mené à la découverte de l’artémisinine, également connue sous le nom de Qing Hao Su (青蒿素) et de ses dérivés semi-synthétiques qui possèdent l’action la plus rapide de tous les médicaments actuels contre la malaria. Cet ouvrage présente le processus de modernisation et d’internationalisation d’un traitement utilisé en médecine traditionnelle chinoise depuis plus de 1600 ans et qui contient un grand nombre de documents non publiés ou accessibles uniquement aux personnes parlant le mandarin. Le livre : – recense la structure chimique, les propriétés chimiques, le mode d’extraction, les dérivés, la réaction chromogénique, la pharmacologie générale, la toxicologie, etc. de l’Artemisia ; – inclut des données expérimentales - y compris les résultats de la cristallographie aux rayons X - pour déterminer la configuration moléculaire en utilisant les effets de diffusion des atomes d’oxygène par diffraction des rayons X ; – présente les progrès récents de la dihydroartémisinine et de la nouvelle génération d’antipaludiques, ainsi que les progrès des tests d’efficacité de l’artémisinine et de ses dérivés contre le cancer et diverses autres infections et maladies.
