Cefotaxime diffusion into cerebrospinal fluid of children with meningitis
Abstract:
Cefotaxime diffused consistently and in therapeutic levels into the cerebrospinal fluid (CSF) of 13 children successfully treated for bacterial meningitis. CSF cefotaxime levels early (6.0 micrograms/ml) and late (1.2 micrograms/ml) in treatment were severalfold the MBCs for the infecting organisms. After a single 40-mg/kg dose to each of five infants with ventriculostomies, mean CSF levels of cefotaxime were 6.4, 5.7, and 4.5 micrograms/ml at 2, 4, and 6 h, respectively.
Insights
Cefotaxime effectively treats bacterial meningitis by reaching therapeutic levels in cerebrospinal fluid (CSF). This antibiotic achieved concentrations significantly higher than required to combat the meningitis-causing bacteria in children.
Area of Science:
- Pediatric Infectious Diseases
- Neuroscience
- Pharmacology
Background:
- Bacterial meningitis remains a critical pediatric infection.
- Effective antibiotic penetration into the cerebrospinal fluid (CSF) is essential for treatment success.
- Cefotaxime is a third-generation cephalosporin with broad-spectrum activity.
Purpose of the Study:
- To evaluate cefotaxime's penetration and concentration in the CSF of pediatric patients with bacterial meningitis.
- To determine if CSF cefotaxime levels are therapeutic and exceed the minimum bactericidal concentrations (MBCs) of causative organisms.
Main Methods:
- Analysis of CSF samples from 13 children treated for bacterial meningitis.
- Measurement of cefotaxime concentrations at various time points during treatment.
- Pharmacokinetic assessment in five infants with ventriculostomies after a single dose.
Main Results:
- Consistent and therapeutic levels of cefotaxime were observed in the CSF of treated children.
- Early and late CSF cefotaxime levels were severalfold higher than the MBCs of the infecting pathogens.
- Pharmacokinetic data in infants showed sustained CSF cefotaxime concentrations post-administration.
Conclusions:
- Cefotaxime demonstrates excellent penetration into the CSF in pediatric patients with bacterial meningitis.
- Achieved CSF cefotaxime concentrations support its efficacy in treating this serious infection.
- The drug is well-tolerated and achieves therapeutic levels crucial for combating bacterial meningitis.
