Gram-negative bacillary meningitis
The Medical Clinics of North America
|March 1, 1985
Abstract:
The incidence of gram-negative bacillary meningitis has increased significantly in the past two decades. Approximately two thirds of all reported cases have occurred after neurosurgical procedures. With the development of the newer cephalosporins, the overall mortality rate has decreased from 40 to 80 per cent to 10 to 20 per cent.
Insights
Gram-negative bacillary meningitis, often occurring post-neurosurgery, has seen increased incidence. Newer cephalosporins have significantly reduced mortality rates for this serious infection.
Area of Science:
- Neuroscience
- Infectious Diseases
- Critical Care Medicine
Background:
- The incidence of gram-negative bacillary meningitis (GNBM) has risen over the last 20 years.
- A significant proportion, approximately two-thirds, of GNBM cases are associated with neurosurgical procedures.
Purpose of the Study:
- To review the trends in gram-negative bacillary meningitis incidence.
- To highlight the impact of neurosurgery on meningitis cases.
- To assess the effect of modern antibiotic therapy on patient outcomes.
Main Methods:
- Retrospective analysis of reported gram-negative bacillary meningitis cases.
- Review of neurosurgical complication data.
- Evaluation of mortality rates in relation to treatment advancements.
Main Results:
- A notable increase in the incidence of gram-negative bacillary meningitis has been observed.
- Gram-negative bacillary meningitis frequently complicates neurosurgical interventions.
- The introduction of newer cephalosporins has led to a substantial decrease in mortality.
Conclusions:
- Gram-negative bacillary meningitis remains a significant concern, particularly following neurosurgery.
- Advances in antibiotic therapy, specifically newer cephalosporins, have dramatically improved survival rates for GNBM.
- Continued vigilance and appropriate antibiotic strategies are crucial for managing post-neurosurgical meningitis.
