[Treatment of neurosurgical bacterial meningitis using the combination of ceftriaxone-fosfomycin].

16 patients with bacterial meningitis following a neurosurgical procedure were given a combination of ceftriaxone and fosfomycin. 8 microorganism were isolated: 2 Staphylococcus epidermidis, 1 Staphylococcus aureus, 1 Neisseria meningitidis, 1 Streptococcus pneumoniae, 1 Haemophilus influenzae, 1 Serratia marcescens and 1 Aeromonas hydrophila. No pathogen was identified in the remaining cases. All of the isolated strains were susceptible to both antibiotics. In vitro, neither synergy nor antagonism were observed between the two antimicrobial agents. The acute infectious episode resolved in all patients. One relapse only was observed, in a patient with meningitis related to a ventricular shunt, and successfully treated by the same therapeutic schedule associated with removal of the tubing. Lastly, CSF concentrations of both antibiotics were assayed and found to be comparable with those reported by most author.
