Abstract

Based on the cerebral malaria coma scale, 39 falciparum malaria autopsy cases from the Hospital for Tropical Diseases, Mahidol University, Bangkok, Thailand were divided into two groups of patients that had either cerebral malaria or non-cerebral malaria. We then studied significant pathological differences, such as parasitized erythrocyte (PRBC) sequestration, ring hemorrhages and cerebral edema, between these two groups in order to investigate the correlation between the clinical coma scale and pathological findings. Patients with a coma grade of 2 and higher were designated as having cerebral malaria, and had erythrocyte PRBC sequestration in cerebral microvessels. Ninety four percent (94%) of cerebral microvessels showed PRBC sequestration when quantitatively analyzed. On the other hand, only 13% of cerebral microvessels showed sequestration in non-cerebral malaria patients with a coma grade of 1 and lower, although some degree of PRBC sequestration was found in 50% of these patients. Our study, therefore, clearly demonstrated that the degree of the PRBC sequestration in cerebral microvessels appeared to correlate closely with the clinical coma scale.

    In vivo assessments to determine the neuroanatomical correlates of malaria-related coma and subsequent neurologic sequelae have been limited to gross clinical assessments. Autopsy studies have provided insights into the clinicopathologic correlates of fatal cases and indicate a range of pathological findings [3,13]. These include sequestration of parasitized red blood cells in brain capillaries with diffuse oedema, petechial hemorrhages in the brain parenchyma surrounding ruptured vessels, ring hemorrhages; parenchymal necrosis with perivascular oedema and neuronal cell loss and microglial aggregates (Durck's granulomas).
