Neonatal meningitis. The ventricle as a bacterial reservoir
Abstract:
We reviewed autopsies of neonates who had died of meningitis. Plexitis and ventricular exudate were usually present. While the pathogenetic relationship between these two phenomena is uncertain, it is possible that the glycogen-rich choroid plexus of the lateral ventricles not only facilitates local bacterial growth but also acts as a bacterial reservoir relatively resistant to antimicrobial agents. We suggest that more drastic approaches than parenteral antimicrobial therapy may be indicated to reduce further the morbidity and mortality of neonatal meningitis.
Insights
Neonatal meningitis autopsies revealed plexitis and ventricular exudate. The choroid plexus may harbor bacteria, suggesting more aggressive treatments are needed beyond antibiotics.
Area of Science:
- Neonatal pathology
- Infectious diseases
- Microbiology
Background:
- Neonatal meningitis is a serious infection with significant mortality.
- Understanding the pathological mechanisms is crucial for improving treatment outcomes.
Purpose of the Study:
- To investigate the pathological findings in neonates who died from meningitis.
- To explore the potential role of the choroid plexus in the pathogenesis of neonatal meningitis.
Main Methods:
- Review of autopsy findings in neonates diagnosed with meningitis.
- Histopathological examination focusing on the central nervous system.
Main Results:
- Plexitis (inflammation of the choroid plexus) and ventricular exudate were consistently observed.
- The choroid plexus, rich in glycogen, may serve as a bacterial reservoir resistant to antimicrobial agents.
Conclusions:
- The choroid plexus's role in bacterial colonization warrants further investigation.
- Current parenteral antimicrobial therapy might be insufficient, necessitating consideration of more aggressive treatment strategies for neonatal meningitis.
