WHAT IS KNOWN AND OBJECTIVE: To compare the penetration of vancomycin into cerebrospinal fluid (CSF) in patients with postoperative intracranial infection and community-acquired meningitis, and to identify related factors influencing the penetration in these two diseases.
METHODS: The concentrations of vancomycin in serum and CSF were determined by enzyme amplified immunoassay, and the CSF-to-serum ratios were calculated. The correlation between CSF-to-serum ratios of vancomycin and CSF elements was analyzed.
RESULTS AND DISCUSSION: In postoperative intracranial infection patients and community-acquired meningitis patients, the vancomycin concentration in CSF was 1.90 ± 1.29 mg/L and 2.47 ± 1.15 mg/L, while the CSF-to-serum ratio was 0.19 ± 0.12 and 0.26 ± 0.12, respectively. There was a significant correlation between vancomycin serum concentration and bodyweight (P < 0.05). The CSF-to-serum ratio in postoperative intracranial infection patients was correlated to white blood cell count in CSF. However, in community-acquired meningitis patients, no relationship was seen with regards to CSF white blood cell count, protein or glucose.
WHAT IS NEW AND CONCLUSION: Cerebrospinal fluid vancomycin penetration was similar in postoperative intracranial infection and community-acquired meningitis patients. The CSF-to-serum ratio was only correlated to CSF white blood cell count in postoperative intracranial infection patients.
