Cerebral malaria. A disseminated vasculomyelinopathy

|May 1, 1978
Summary
Cerebral malaria, a severe Plasmodium falciparum infection, may be a hyperegic reaction causing CNS vasculomyelinopathy. Early corticosteroid treatment, like dexamethasone, alongside antimalarials, could interrupt this process.
Area of Science:
- Neurology
- Immunology
- Infectious Diseases
Background:
- Cerebral malaria is a severe neurological complication of Plasmodium falciparum infection.
- Pathological features suggest a disseminated vasculomyelinopathy and a hyperegic immune response in the central nervous system (CNS).
Purpose of the Study:
- To investigate the neuropathological features of cerebral malaria.
- To propose a mechanism for CNS involvement in Plasmodium falciparum malaria.
- To evaluate potential therapeutic interventions.
Main Methods:
- Neuropathologic examination of 19 fatal cerebral malaria cases.
- Comprehensive review of existing literature on cerebral malaria.
Main Results:
- Findings support viewing cerebral malaria as a disseminated vasculomyelinopathy, a hyperegic CNS reaction to Plasmodium falciparum.
- The proposed pathogenesis involves initial vasculopathy, altered endothelial permeability, leading to brain edema, perivascular changes, demyelination, and gliosis.
- Corticosteroids, specifically parenteral dexamethasone, show potential to interrupt this pathological cascade.
Conclusions:
- Cerebral malaria involves a complex neuropathological process initiated by vasculopathy.
- Early administration of corticosteroids, such as dexamethasone, alongside standard antimalarial therapy is recommended upon initial CNS involvement signs.
- This therapeutic approach may mitigate severe neurological damage in cerebral malaria.
