Scientific title
Study objectivesCytoadherence of parasitised erythrocytes to microvascular endothelium is the pathological hallmark of falciparum malaria. In vitro studies show that levamisole, a specific alkaline-phosphatase inhibitor, decreases adhesion of parasitised erythrocytes to CD36. This pilot study aims to examine whether this happens in vivo.
Ethics approval(s)Oxford Tropical Research Ethics Committee gave approval on the 1st June 2006 (ref: 007-06)
Health condition(s) or problem(s) studiedFalciparum malaria
InterventionPatients admitted to Mae Sot Hospital with uncomplicated falciparum malaria will be randomised to either adjunctive treatment with a single dose of 150 mg oral levamisole hydrochloride, or no adjunctive treatment. Antimalarial treatment will be oral quinine and doxycycline.

Peripheral blood parasitaemia and parasite stages will be assessed frequently. If sequestration of parasitised erythrocytes is reduced, an initial increase in peripheral blood parasitaemia and appearance of more mature parasites in the peripheral blood can be expected.
Intervention typeDrug
PhaseNot Applicable
Drug / device / biological / vaccine name(s)Levamisole hydrochloride, quinine and doxycycline
Primary outcome measure(s)

Sequential assessment of peripheral blood parasitaemia and parasite stages.
