Cefepime and cefpirome are new beta-lactamase resistant parenteral cephalosporin derivatives whose spectrum of activity makes them suitable for use in the treatment of severe infections such as bacterial meningitis. However, the published information on the penetration of these new agents into human CSF and on their use in the treatment of bacterial meningitis are really scarce. Experimental studies have shown that cefepime and cefpirome penetrated remarkably well into the CSF of animals infected with Streptococcus pneumoniae, Streptococcus agalactiae, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Haemophilus influenzae type b or Pseudomonas aeruginosa. The mean changes in bacterial colony count in CSF after cefpirome or cefepime administration express the antibacterial activity of these drugs. Studies in patients show that cefepime and cefpirome crossed the blood-brain barrier and reached concentrations in the CSF that are bactericidal against most potential pathogens. Higher levels are likely to be achieved with multiple dosing and in the presence of inflamed meninges. No study has been performed to investigate the efficacy of cefpirome in the treatment of bacterial meningitis. Cefepime was as effective and safe as cefotaxime for treatment of patients with bacterial meningitis as shown in the only clinical trial.

PMID:Diffusion of 3-quaternary ammonium cephem antibiotics into cerebrospinal fluid of patients with bacterial meningitis. 873 50

A 64-year-old man with fever, appetite loss, and pain in the back of the neck visited our hospital. We diagnosed him as having bacterial meningitis because of pleocytosis of the cerebrospinal fluid, and started treatment with antibiotics. Multiple cerebral infarcts were found on brain MRI. We suspected that the origin of the bacterial meningitis was infective endocarditis, and administered Cefepime and Gentamicin according to the guidelines for treatment of infective endocarditis. Three days later, he became drowsy and had myoclonus and flapping of the extremities. An electroencephalograph showed generalized periodic discharge and a triphasic wave pattern. We thought that the cause of disturbance in consciousness was Cefepime-induced encephalopathy, and stopped administration of Cefepime. A few days later, he became clear, and the myoclonus and flapping disappeared. It was difficult to distinguish between non-convulsive status epilepticus and Cefepime-induced encephalopathy. However, since stopping Cefepime treatment had made the patient clear, we diagnosed his condition as Cefepime-induced encephalopathy, which often occurs in patients with renal or liver dysfunction, or in brain infarction or meningitis, which results in blood-brain barrier disruption. Thus, care should be taken when administering Cefepime to such patients.
