An immunofluorescence study of cerebral malaria. A correlation with histopathology.
Histopathologic and immunopathologic features of cerebral malaria have been defined in a study of six autopsy cases with severe Plasmodium falciparum infection. In five cases, immunofluorescent studies demonstrated intense deposition of P falciparum antigen, IgG, and fibrin in cerebral vessels associated with the histopathologic finding of hemorrhage in the white matter of cerebrum and cerebellum regardless of the presence of parasitized erythrocytes in the cerebral vessels. Immunofluorescent study also demonstrated the extravascular deposits of P falciparum granular antigen associated with acute inflammatory lesion in cerebral tissue in one case. These findings suggested that the immunopathogenic mechanism may in some way play a role in the pathogenesis of cerebral malaria.
