[Survival analysis of acute pyogenic meningitis in children]
Abstract:
In order to determine the survival curves of lethality in acute bacterial meningitis (ABM) in children, we reviewed the charts of all patients admitted to the Hospital Couto Maia from January 1990 to December 1992. The Kaplan-Meir analysis was used to compare the survival rate and hospitalar permanence of patients with identified pathogens with those whose bacteria were not determined. The same analysis was used to compare the curves of the three most frequent agents. Statistical difference between the identified and nonidentified groups was not observed. The analysis of the three curves shows that the first 24 hours were responsible for the most elevated lethality rate. When the curves are compared, it is clear that S. pneumoniae has the most important intrahospitalar lethality and N. meningitidis the most benign evolution. We conclude that efforts have to be made to determine which variables are related to prognosis of ABM at the first day of hospital admission.
Insights
This study analyzed childhood acute bacterial meningitis (ABM) survival rates. Streptococcus pneumoniae showed higher lethality, while Neisseria meningitidis had a better prognosis, highlighting the need for early prognostic variable identification.
Area of Science:
- Pediatrics
- Infectious Diseases
- Epidemiology
Context:
- Acute bacterial meningitis (ABM) remains a significant cause of child mortality.
- Understanding survival curves and prognostic factors is crucial for improving outcomes.
Purpose:
- To determine lethality survival curves in pediatric acute bacterial meningitis (ABM).
- To compare survival rates based on identified pathogens versus unidentified bacteria.
- To analyze survival curves for the three most frequent bacterial agents.
Summary:
- A retrospective chart review of pediatric ABM patients from 1990-1992 was conducted.
- Kaplan-Meier analysis revealed no statistical difference in survival between identified and unidentified pathogen groups.
- Streptococcus pneumoniae exhibited higher in-hospital lethality, whereas Neisseria meningitidis showed a more benign clinical course.
Impact:
- The initial 24 hours post-admission are critical, associated with the highest lethality.
- Findings underscore the importance of identifying prognostic variables early in hospital admission for ABM.
- Differentiated lethality among common bacterial agents suggests pathogen-specific management considerations.
