Intracranial pressure in childhood cerebral malaria
Insights
In Gambian children with cerebral malaria, elevated cerebrospinal fluid pressure was common but not linked to fatal outcomes. Further research into osmotic agents for treating childhood cerebral malaria is warranted.
Area of Science:
- Pediatrics
- Infectious Diseases
- Neurology
Background:
- Cerebral malaria is a severe complication of Plasmodium falciparum infection.
- Raised intracranial pressure (ICP) is a suspected factor in cerebral malaria mortality.
- Understanding ICP dynamics is crucial for improving outcomes in affected children.
Purpose of the Study:
- To investigate the relationship between cerebrospinal fluid (CSF) opening pressure and outcomes in Gambian children with acute cerebral malaria.
- To assess cerebral perfusion pressure (CPP) in fatal versus surviving cases.
- To evaluate the immediate impact of lumbar puncture on clinical status.
Main Methods:
- Lumbar punctures were conducted on 40 Gambian children diagnosed with acute cerebral malaria.
- CSF opening pressure and CPP were measured.
- Clinical status and outcomes (survival vs. fatality) were recorded and compared.
Main Results:
- Elevated CSF opening pressure (≥ 20 cmH2O) was observed in 80% of the children.
- Mean CSF opening pressure did not significantly differ between fatal (110 mmH2O) and surviving (131 mmH2O) cases.
- Cerebral perfusion pressures were similar in both groups (64 mm Hg).
Conclusions:
- While elevated ICP is frequent in childhood cerebral malaria, it may not be the primary determinant of mortality.
- Brain swelling and brain-stem compression could still contribute to sudden death, particularly from respiratory arrest.
- Prospective studies on osmotic agents for childhood cerebral malaria are justified to explore potential therapeutic interventions.
Abstract:
Lumbar punctures were performed in 40 Gambian children with acute cerebral malaria aged between 18 months and 10 years. The mean opening pressure was elevated in 32 (80%) of the children, but was not significantly different in the 14 fatal cases compared with survivors: 110 (standard deviation 71) versus 131 (58) mm of cerebrospinal fluid respectively. Cerebral perfusion pressures were also similar in the 2 groups: 64 (20) mm Hg versus 64 (11) mm Hg respectively. There was no clear clinical evidence of raised intracranial pressure, and no evidence of deterioration immediately following lumbar puncture. Nevertheless brain swelling, and consequent brain-stem compression, may contribute to a fatal outcome in cerebral malaria--particularly in those children who die from sudden respiratory arrest. A prospective evaluation of osmotic agents in childhood cerebral malaria seems to be justified.
