Atorvastatin prevents Plasmodium falciparum cytoadherence and endothelial damage

<p>Abstract</p> <p>Background</p> <p>The adhesion of <it>Plasmodium falciparum </it>parasitized red blood cell (PRBC) to human endothelial cells (EC) induces inflammatory processes, coagulation cascades, oxidative stress and apoptosis. These pathological processes are suspected to be responsible for the blood-brain-barrier and other organs' endothelial dysfunctions observed in fatal cases of malaria. Atorvastatin, a drug that belongs to the lowering cholesterol molecule family of statins, has been shown to ameliorate endothelial functions and is widely used in patients with cardiovascular disorders.</p> <p>Methods</p> <p>The effect of this compound on PRBC induced endothelial impairments was assessed using endothelial co-culture models.</p> <p>Results</p> <p>Atorvastatin pre-treatment of EC was found to reduce the expression of adhesion molecules and <it>P. falciparum </it>cytoadherence, to protect cells against PRBC-induced apoptosis and to enhance endothelial monolayer integrity during co-incubation with parasites.</p> <p>Conclusions</p> <p>These results might suggest a potential interest use of atorvastatin as a protective treatment to interfere with the pathophysiological cascades leading to severe malaria.</p
