Rectal artesunate suppositories are a useful option for pre-referral treatment of severe malaria, specifically in children under 6 years of age in remote malaria-endemic areas. The main challenges are to improve the solubility of drugs in the rectal fluids and prevent the product from turning rancid or melting in a tropical climate.
Little is known on the use of artesunate compared with quinine for the treatment of imported malaria cases in nonendemic countries with a high level of care. Therefore, we compared the 2 treatments in terms of mortality and hospital and intensive care unit (ICU) discharge rates.
The Democratic Republic of the Congo adopted the strategy of using, at the community level, a dose of rectal artesunate as a pre-referral treatment for severe malaria amongst children under 5 years who could not quickly reach a health care facility and take oral medication. However, the adherence to referral advice after the integration of this strategy and the acceptability of the strategy were unknown.
We found that AMA1 was a major target of naturally acquired invasion-inhibitory antibodies that were highly prevalent in malaria-endemic populations and showed a high degree of allele specificity. Significantly, the prevalence of inhibitory antibodies to different alleles varied substantially within populations and between geographic locations.
Our results indicate that there is scope to strengthen already effective methods of communication, in addition to a strong demand by scientists (expressed by 79.9 % of respondents) to develop new, creative modes of public engagement.
We prospectively evaluated a cohort of 123 patients in France who had severe imported malaria that was treated with artesunate; our evaluation focused on outcome, adverse events, and postartesunate delayed-onset hemolysis (PADH). Of the 123 patients, 6 (5%) died. Overall, 97 adverse events occurred.
Sulphadoxine-pyrimethamine + amodiaquine therapy was as efficacious as sulphadoxine-pyrimethamine + artesunate, but more efficacious than sulphadoxine-pyrimethamine alone in the treatment of uncomplicated P. falciparum malaria in Mali.
The prevalence of isolates with a reduced susceptibility to MQ remains high and stable in Dakar. Since 2004, the prevalence of CQ resistance decreased, but rebounded in 2013 in Dakar. PND, PPQ and PVB showed high in vitro activity in P. falciparum parasites from Dakar
In this study, we aimed to elucidate the molecular mechanisms underlying ART-induced cell death. We first confirmed that ART induces apoptotic cell death in cancer cells. Interestingly, we found that ART preferably accumulates in the lysosomes and is able to activate lysosomal function via promotion of lysosomal V-ATPase assembly.
This review presents a background for recommending artesunate as the first-line treatment of severe malaria in children and adults, and interventions that are recommended to accelerate access to injectable artesunate.
