Bacterial meningitis in older neonates
Abstract:
During a five-year period, 24 patients' conditions (age range, 2 to 6 weeks) were diagnosed, and they were treated for bacterial meningitis. Organisms recovered from the CSF included group B Streptococcus (n = 6), Escherichia coli (n = 5), Listeria monocytogenes (n = 5), Hemophilus influenzae (n = 4), Streptococcus pneumoniae (n = 2), and group D and group A Streptococcus (one each). Initial antimicrobial therapy must include antibiotics that are effective across this spectrum of potential pathogens. Symptoms and signs were often subtle. Six children (25%) experienced major neurologic residua, including five patients (21%) in whom hydrocephalus developed. Ultrasound examination of the head at the end of therapy was an effective technique for early assessment of neurologic sequelae.
Insights
Bacterial meningitis in infants (2-6 weeks) requires broad-spectrum antibiotics due to diverse pathogens like Group B Streptococcus and E. coli. Early ultrasound can detect neurologic issues such as hydrocephalus, a common sequela.
Area of Science:
- Neonatal infectious diseases
- Pediatric neurology
- Microbiology
Background:
- Bacterial meningitis is a serious infection in neonates.
- Common causative agents vary and require broad-spectrum antibiotic coverage.
- Neurologic sequelae are a significant concern in affected infants.
Purpose of the Study:
- To identify common bacterial pathogens causing meningitis in neonates.
- To evaluate the incidence of neurologic sequelae.
- To assess the utility of head ultrasound in detecting these sequelae.
Main Methods:
- Retrospective analysis of 24 neonates diagnosed with bacterial meningitis over five years.
- Identification of causative organisms from cerebrospinal fluid (CSF) cultures.
- Clinical assessment for neurologic outcomes and use of head ultrasound.
Main Results:
- Group B Streptococcus and Escherichia coli were the most frequent pathogens.
- Twenty-five percent of patients experienced major neurologic residua.
- Hydrocephalus developed in 21% of patients.
- Head ultrasound proved effective in early assessment of neurologic sequelae.
Conclusions:
- Empirical antibiotic therapy should target a wide range of potential neonatal meningitis pathogens.
- Neurologic complications, particularly hydrocephalus, are common.
- Head ultrasound is a valuable tool for the early detection of neurologic sequelae in neonates treated for bacterial meningitis.
