Cerebral malaria (CM) is a severe complication of malaria, in which cytokine production can produce immunopathological consequences. Cytokines can up-regulate prostaglandin synthesis via an increase in cyclooxygenase (COX) enzyme activity. We investigated the expression of COX enzymes, COX-1 and COX-2, in the brain by use of murine models of CM and of malaria without cerebral involvement. Altho...

Cerebral malaria is a fatal complication of infection by Plasmodium falciparum in man. The neurological symptoms that characterize this form of malarial disease are accompanied by the adhesion of infected erythrocytes to the vasculature of the brain. To study this phenomenon in vivo, an acute phase severe combined immunodeficiency (SCID) mouse model was developed in which sequestration of P. fa...

Parasite virulence, an important factor contributing to the severity of Plasmodium falciparum infection, varies among P. falciparum strains. Relatively little is known regarding markers of virulence capable of identifying strains responsible for severe malaria. We investigated the effects of genetic variations in the P.f. merozoite surface protein 2 gene (msp2) on virulence, as it was previousl...

Cerebral malaria is the most common cause of non-traumatic encephalopathy in the world. The mainstay of therapy is either quinine or artemisinin, both of which are effective antimalarials. The clinical picture of cerebral malaria may persist or even become worse in spite of the clearance of parasites from blood. The death rate is unacceptably high even with effective antimalarials in tertiary c...

The first in vivo magnetic resonance study of experimental cerebral malaria is presented. Cerebral involvement is a lethal complication of malaria. To explore the brain of susceptible mice infected with Plasmodium berghei ANKA, multimodal magnetic resonance techniques were applied (imaging, diffusion, perfusion, angiography, spectroscopy). They reveal vascular damage including blood-brain barri...

The most common indication for epilepsy surgery is temporal lobe epilepsy (TLE) which usually is divided into two categories, mesial and lateral TLE. The commonest pathology underlying mesial temporal lobe epilepsy (MTLE) is mesial temporal sclerosis (MTS); we report on a 50-year-old male patient, who contracted cerebral malaria and developed MTLE shortly thereafter. Magnetic resonance imaging ...

Cerebral malaria is the most severe and rapidly fatal neurological complication of Plasmodium falciparum infection and responsible for more than two million deaths annually. The current therapy is inadequate in terms of reducing mortality or post-treatment symptoms such as neurological and cognitive deficits. The pathophysiology of cerebral malaria is quite complex and offers a variety of targe...

Cerebral malaria is the most important manifestation of severe Plasmodium falciparum infection. The clinical picture in South East Asian adults differs from that in African children. The children are more likely to have abnormal brain stem reflexes, signs suggestive of cerebral herniation, and raised CSF opening pressure, and to suffer persistent neurological sequelae. The mortality remains hig...

The pathogenesis of cerebral malaria from Plasmodium falciparum infection is thought to involve inflammation of the central nervous system. Since monocyte chemoattractant protein 1 (MCP-1) is a chemokine strongly involved in the inflammatory process, we here study MCP-1 gene polymorphisms in association with severe or cerebral malaria in Thailand. Malaria patients in the northwest of Thailand w...
