BackgroundCerebrospinal fluid (CSF) penetration of vancomycin through the blood-brain barrier is poor but important inflammation improved it. Hence, vancomycin is recommended for the treatment of community meningitis. However, what about mild inflammatory health care-associated meningitis? The aim of this study was to evaluate the impact of vancomycin diffusion on CSF in Staphylococcus epidermidis health care-associated meningitis.Case DescriptionThis was a retrospective study of all consecutive patients with S. epidermidis CSF shunt-associated infection, which was treated by continuous intravenous vancomycin after standard of care (60 mg/kg/d after a loading dose of 15 mg/kg). Patient outcome, CSF protein level, and vancomycin concentration in CSF and serum were assessed. We report 6 consecutives cases. Clinical and biologic manifestations were of mild intensity. Meningeal permeability was moderately altered with low CSF protein levels. Despite appropriate vancomycin dosage resulting in high serum concentrations, CSF remained below the S. epidermidis minimal inhibitory concentration.ConclusionsWe propose to reassess vancomycin use as first-line therapy when meningeal inflammation is mild-to-moderate in favor of antibiotics, which have a better CSF penetration.Copyright © 2016 Elsevier Inc.
