Pneumococcal meningitis in children: prognostic indicators and outcome

Area of Science:

• Pediatric Infectious Diseases
• Neurology
• Epidemiology

Background:

• Pneumococcal meningitis remains a significant cause of childhood morbidity and mortality.
• Understanding outcomes and predictive factors is crucial for improving pediatric care.
• This study examines a cohort of children diagnosed with pneumococcal meningitis over a 25-year period.

Purpose of the Study:

• To analyze the mortality and sequelae rates in children with pneumococcal meningitis.
• To identify clinical and laboratory factors associated with mortality and neurological sequelae.
• To compare pediatric outcomes with those typically seen in adult populations.

Main Methods:

• Retrospective analysis of 83 children diagnosed with pneumococcal meningitis between 1970 and 1994.
• Data collection included patient demographics, clinical presentation, cerebrospinal fluid (CSF) analysis, and outcomes (mortality, sequelae).
• Statistical analysis identified factors associated with mortality and sequelae.

Main Results:

• Overall mortality rate was 17%, with significantly higher rates in secondary referrals (35%) compared to primary referrals (7%).
• Neurological sequelae (25%) and hearing loss (19%) were observed in 36% of survivors.
• Factors predicting mortality included coma, respiratory distress, shock, high CSF protein, low peripheral white blood cell count, and low serum sodium. Coma and low CSF glucose predicted sequelae.

Conclusions:

• Pneumococcal meningitis in children has a lower mortality rate than in adults, who often succumb to cardiorespiratory failure.
• Neurological sequelae are a major concern for surviving children.
• Coma, respiratory distress, and shock are critical indicators for predicting severe outcomes in pediatric pneumococcal meningitis.
