Abstract:
This study describes the bacteriology, cerebrospinal fluid (CSF) findings, and mortality of neonatal meningitis over an 11-year period. The minimum incidence of neonatal meningitis at Tygerberg Hospital is 0.72/1000 live births/year. Eighty-eight patients were included in the study. Median birthweight and age at diagnosis were 2320 g and 12 days, respectively. CSF culture was positive in 77 (88 per cent), blood culture was positive in 51 (57 per cent), and Gram stain was positive in 58 (66 per cent). The most frequently cultured organisms were Group B Streptococcus, Klebsiella pneumoniae, and E. coli. Thirty (34 per cent) patients died, the majority within 72 h after admission. The death rate was significantly increased in babies with a birthweight of less than 1500 g (59 per cent). Increased total CSF protein was associated with an increased risk of death. Normal CSF cell count, total CSF protein and CSF glucose were found in six infants.
Insights
Neonatal meningitis is a serious infection with a high mortality rate, particularly in low birthweight infants. Early diagnosis and treatment are crucial for improving outcomes in neonatal bacterial meningitis.
Area of Science:
- Neonatalogy
- Infectious Diseases
- Microbiology
Background:
- Neonatal meningitis poses a significant threat to infant survival.
- Understanding causative pathogens and risk factors is vital for effective management.
Purpose of the Study:
- To analyze the bacteriology, cerebrospinal fluid (CSF) findings, and mortality patterns of neonatal meningitis.
- To identify key factors influencing survival rates in affected infants.
Main Methods:
- Retrospective analysis of 88 neonatal meningitis cases over 11 years.
- Review of patient demographics, clinical data, CSF, and blood culture results.
- Correlation of clinical parameters with mortality outcomes.
Main Results:
- Minimum incidence of 0.72/1000 live births.
- Common pathogens included Group B Streptococcus, Klebsiella pneumoniae, and E. coli.
- Mortality rate was 34%, with increased risk in infants <1500g and elevated CSF protein.
Conclusions:
- Neonatal meningitis has a substantial mortality rate, especially in vulnerable infants.
- Timely identification of pathogens and risk stratification are essential for clinical care.
- Further research into preventative strategies and targeted therapies is warranted.
