The sequelae of acute purulent meningitis in childhood
Insights
Acute purulent meningitis in children can lead to long-term neurological and psychological issues, particularly in infants. Early illness severity correlates with these sequelae, impacting cognitive function and brain health.
Area of Science:
- Pediatrics
- Neurology
- Infectious Diseases
Background:
- Acute purulent meningitis is a serious childhood infection with potential long-term consequences.
- Understanding the incidence and nature of sequelae is crucial for patient management and prognosis.
Purpose of the Study:
- To assess the incidence and types of sequelae following acute purulent meningitis in children.
- To investigate the relationship between acute illness severity and the development of sequelae.
- To correlate different methods for identifying sequelae.
Main Methods:
- Retrospective study of 122 children diagnosed with acute purulent meningitis (1952-1956).
- Follow-up study of 41 survivors 2.5 to 7.5 years post-illness.
- Utilized psychiatric, neurological, electroencephalographic (EEG), and psychological testing for sequelae assessment.
Main Results:
- 12% of children died, all under 12 months of age.
- Among survivors, 26% showed neuropsychiatric and/or psychological sequelae.
- Severity of acute illness positively correlated with neuropsychiatric sequelae, defective intelligence, and psychological brain damage evidence.
Conclusions:
- Acute purulent meningitis poses a significant risk of long-term neurological and psychological deficits in children.
- Illness severity is a key predictor of adverse outcomes.
- EEG abnormalities did not correlate with neuropsychiatric defects.
Abstract:
Of a series of 122 children suffering from acute purulent meningitis at the Children's Hospital, Winnipeg, in the years 1952-56, 12 (9.8%) succumbed, all deaths occurring in those 12 months of age or less. Fortyone of the survivors were re-studied 2.5 to 7.5 years after their acute illness to assess the nature and incidence of sequelae, the relationship of sequelae to the severity of the acute illness, and the correlation between the various methods of identifying sequelae. Five children exhibited psychiatric evidence of organic brain damage; seven, neurological abnormality; 11, electroencephalographic abnormality. Three had defective intelligence and nine psychological test evidence of organic brain damage. Children with sequelae tended to have several abnormal test results, the total number with neuropsychiatric and/or psychological sequelae being 11 (26%). There was a positive correlation between the severity of the acute illness and the presence of neuropsychiatric sequelae; also between neuropsychiatric sequelae, defective intelligence and psychological evidence of brain damage. No correlation existed between the electroencephalographic abnormality and neuropsychiatric defect.
