[The efficacy of intraventricularly administered vancomycin in the case of central nervous system infection caused by enterococcus faecalis]. / Skutecznosc wankomycyny stosowanej dokomorowo w zakazeniu osrodkowego ukladu nerwowego wywolanego przez Enterococcus faecalis.

The case of 40 years old man with subarachnoid hemorrhage with intraventricular bleeding and with consecutive cerebro-meningitis is presented. The bacterial pathogen was Enterococcus faecalis sensitive only to glycopeptide antibiotics. The standard therapy with intravenously administered Vancomycin and Teicoplanin was not effective. Because of the worsening of patient's clinical status and clinical symptoms of sepsis the intraventricular Vancomycin (20 mg/day) was introduced. At the second day of the therapy the gradual patient's recovery was observed. The symptoms typical for meningitis diminished as well as cerebro-spinal fluid (CSF) parameters normalized. There was no bacterial growth in the blood serum and in CSF. As we can observe the intraventricular administration of Vancomycin is efficient method of cerebro-meningitis treatment. In our opinion the blood-brain barrier, even pathologically changed by infection, do not allow antibiotics to penetrate CSF, even in the maximal intravenous doses. In the cases of cerebro-meningitis caused by bacteria sensitive only to glycopeptide antibiotics, the intraventricular administration of the drug might be an alternative way of therapy especially when the doses of intravenous antibiotics need to be reduced.
