Meningitis due to Staphylococcus aureus in children
1Department of Pediatrics, Bowman Gray School of Medicine, Wake Forest University, Brenner Children's Hospital, Winston-Salem, North Carolina 27157.
Summary
Staphylococcus aureus meningitis is rare, often linked to central nervous system (CNS) issues or surgery. In children without known CNS problems, a hidden CNS abnormality may be present and requires investigation.
Area of Science:
- Pediatric Neurology
- Infectious Diseases
- Neurosurgery
Background:
- Meningitis caused by Staphylococcus aureus is infrequent.
- It predominantly affects individuals with pre-existing central nervous system (CNS) abnormalities, such as those with a history of neurosurgery or trauma.
Observation:
- A review of 40 children with S. aureus meningitis was conducted across two medical centers.
- The majority (80%) had known CNS abnormalities, frequently related to neurosurgery for ventriculoperitoneal shunts.
- A significant minority (20%) lacked apparent predisposing CNS factors.
Findings:
- Of the eight patients without known CNS abnormalities, four were immunocompromised.
- The remaining four patients without known risk factors were found to have an occult CNS abnormality upon further investigation.
- This highlights the importance of thorough workup in seemingly uncomplicated cases.
Implications:
- The study underscores the need for a prompt and thorough search for occult CNS abnormalities in children diagnosed with S. aureus meningitis, especially when no clear predisposing factors are identified.
- Early detection of underlying CNS issues is crucial for effective management and improved patient outcomes.
- This research contributes to understanding the diverse etiologies and risk factors associated with S. aureus meningitis in pediatric populations.
