Entry of ciprofloxacin into cerebrospinal fluid during bacterial, viral and tuberculous meningitis.
We studied the entry of ciprofloxacin into the cerebrospinal fluid (CSF) in 37 patients with various types of meningitis (bacterial meningitis 10 patients, viral 12 patients, tuberculous 7 patients). Eight patients were in the control group with normal CSF finding. Mean ciprofloxacin concentrations in the CSF 50-60 minutes after 200 mg of ciprofloxacin was given in infusion were 0.20 +/- 0.12 mg/L in patients with bacterial meningitis, which was significantly higher than in other tested groups (p = 0.0325). Ciprofloxacin achieved concentrations in the CSF 6.5-39% of serum (mean value 15% +/- 9%) in the bacterial meningitis group, while in the groups with viral and tuberculous meningitis the levels were significantly lower (approximately 9% of serum) but still higher than in the control group (approximately 5% of serum). Our data suggest that ciprofloxacin should be very cautiously used in selected patients with bacterial meningitis caused by multiple resistant strains of gram negative bacteria.
