The aim of this study was to provide the first comprehensive spatiotemporal picture of Plasmodium falciparum resistance in various geographic areas in Madagascar. Additional data about the antimalarial resistance in the neighboring islands of the Comoros archipelago were also collected.
Artemisinin, from which the artemether component of Coartem®(artemether/lumefantrine, AL) is derived, is obtained from the plant sweet wormwood (Artemisia annua) which has been used for over 2,000 years as a Chinese herbal remedy. Artemisinin was first identified by Chinese researchers as the active anti-malarial constituent of A. annua and its derivatives were found to be the most potent of all anti-malarial drugs.
This article gives an overview of some of the ongoing challenges that are faced in the prevention, diagnosis and treatment of malaria.
This supplement reviews the contribution made by AL as an ACT to the tremendous progress made in the control of malaria and establishes effective treatment as a cornerstone in the foundation of effective, quality patient care for infants, children and adults with malaria.
This paper reviews the historical experience and current rationale for the use of schools and school children as a complementary, inexpensive framework for planning, monitoring and evaluating malaria control in Africa.
A haplotype block in which a primary polymorphism associated with severe malaria is likely to be encoded was identified in Thai malaria patients.
The discovery of genetically engineered parasite strains that are fully attenuated during the early asymptomatic liver infection and confer complete sterile protection in animal malaria models support the development of a live attenuated sporozoite vaccine for Plasmodium falciparum and its accelerated safety and efficacy testing in malaria challenge models and in malaria endemic areas.
The Pfmsp1 block2 locus presents a very large population sequence diversity. The lack of stable acquisition of novel antibody specificities despite exposure to novel allelic forms is reminiscent of clonal imprinting. The locus appears under antibody-mediated diversifying selection in a variable environment that maintains a balance between the various family types without selecting for sequence variant allelic forms. There is no evidence of positive selection for intra-family sequence diversity, consistent with the observed characteristics of the antibody response.
Basing policies on the best available evidence will help ensure maximum impact in terms of reducing death and illness globally, and, with such a high disease burden globally, this has to be a priority in international health.
