In vitro growth competition experiments that suggest consequences of the substandard artemisinin epidemic that may be accelerating drug resistance in P. falciparum malaria

Artemisinin Resistance in Falciparum Malaria

We reported two cases of complicated falciparum malaria who had poor response to artesunate with delayed parasite clearance times. They were splenectomized patients who were treated with high doses of artemisinin derivatives. Our cases showed the importance of the spleen in the clearance of malaria parasites and had different clinical outcome, one fatal and one recovery. The host factors, the p...

Artemisinin resistance in Plasmodium falciparum malaria.

BACKGROUND Artemisinin-based combination therapies are the recommended first-line treatments of falciparum malaria in all countries with endemic disease. There are recent concerns that the efficacy of such therapies has declined on the Thai-Cambodian border, historically a site of emerging antimalarial-drug resistance. METHODS In two open-label, randomized trials, we compared the efficacies o...

Artemisinin Resistance in Plasmodium falciparum Malaria

Malaria drug - resistance in Iran

Introduction: Malaria is a public health problem for approximately 2.4 billion people, 40% of the world’s population, particularly in the tropical and subtropical countries. Countries in Asia, and Latin America, the islands of the South, West, and central pacific ocean are all affected. Drug resistance is the greatest challenge in combating against malaria. Drug resistance in malaria is now w...

Spread of artemisinin resistance in Plasmodium falciparum malaria.

BACKGROUND Artemisinin resistance in Plasmodium falciparum has emerged in Southeast Asia and now poses a threat to the control and elimination of malaria. Mapping the geographic extent of resistance is essential for planning containment and elimination strategies. METHODS Between May 2011 and April 2013, we enrolled 1241 adults and children with acute, uncomplicated falciparum malaria in an o...
