Insights
Cerebral malaria in Ghanaian children presents with fever, seizures, and altered consciousness, especially in first-time infections. Young children face higher risks of severe disease, long-term effects, and mortality.
Area of Science:
- Pediatrics
- Infectious Diseases
- Tropical Medicine
Background:
- Malaria remains a significant health challenge in West Africa.
- Cerebral malaria, a severe form of the disease, disproportionately affects young children.
- Understanding the clinical presentation and risk factors is crucial for effective management.
Purpose of the Study:
- To describe the clinical characteristics of cerebral malaria in children admitted to a hospital in Ghana.
- To identify risk factors associated with central nervous system involvement and poor outcomes.
- To inform public health strategies for managing severe malaria in endemic regions.
Main Methods:
- Retrospective chart review of 187 children admitted with cerebral malaria in 1993.
- Analysis of clinical presentations, including fever, neurological status, and organomegaly.
- Statistical analysis to determine risk factors for severe disease and mortality.
Main Results:
- Fever, sensorial depression, and convulsions were the most common symptoms in children with their first malaria episode.
- Splenomegaly (50%), hepatomegaly, vomiting, and headache were also frequent.
- Long-term sequelae occurred in 9% and mortality in 6% of cases.
- Risk factors for CNS disease included no prior malaria history and high parasitemia.
- Multiple seizures and prolonged altered consciousness predicted poor outcomes.
Conclusions:
- Young children experiencing their first malaria episode are vulnerable to severe cerebral malaria.
- Prompt recognition and management of severe malaria symptoms are vital to reduce mortality and long-term complications.
- Targeted interventions for high-risk groups are needed as malaria incidence rises in West Africa.
Abstract:
A retrospective chart review for the 1993 calendar year identified 187 children with cerebral malaria admitted to a large teaching hospital in central Ghana, West Africa. The most common clinical presentation was fever, sensorial depression and convulsions in young children experiencing their first episode of malaria. One-half had splenomegaly. Additional features, seen in decreasing frequency, were hepatomegaly, vomiting, abdominal pain and headache. Long term sequelae were identified in 9% and mortality in 6%. Risk factors for central nervous system disease were negative history for previous malaria (P < 0.005) and a high percentage of parasitemia (P < 0.001). Death or long term sequelae were associated with multiple seizures and prolonged sensorial depression. The incidence of malaria is currently increasing in Western Africa and young children are more likely than older children to develop severe disease.
