BACKGROUND Plasmodium vivax is more common than P. falciparum as a cause of malaria in many parts of the tropics outside Africa. P. falciparum infection has harmful effects in pregnancy, but the effects of P. vivax have not been characterised. We investigated the effects of P. vivax infection during pregnancy. METHODS Since 1986, pregnant Karen women(More)
BACKGROUND The effects of malaria and its treatment in the first trimester of pregnancy remain an area of concern. We aimed to assess the outcome of malaria-exposed and malaria-unexposed first-trimester pregnancies of women from the Thai-Burmese border and compare outcomes after chloroquine-based, quinine-based, or artemisinin-based treatments. METHODS We(More)
Platelet-activating factor (PAF) is a potent endogenous proinflammatory mediator implicated in the pathogenesis of septic shock. A double-blind randomized placebo-controlled trial of an intravenous PAF receptor antagonist (lexipafant) was conducted with 131 adult Thai patients with suspected severe sepsis (66 of whom had positive blood cultures). Detailed(More)
To investigate the rosette formation properties of Plasmodium vivax, blood was sampled from 26 adult Thai patients admitted with acute P. vivax malaria and a predominance of trophozoite and schizont stages in their peripheral blood smears. In each case, P. vivax-infected cells formed spontaneous rosettes with two or more uninfected red blood cells. Rosette(More)
There are ~660,000 deaths from severe malaria each year. Intravenous artesunate (i.v. ARS) is the first-line treatment in adults and children. To optimize the dosing regimen of i.v. ARS, the largest pooled population pharmacokinetic study to date of the active metabolite dihydroartemisinin (DHA) was performed. The pooled dataset consisted of 71 adults and(More)
