BACKGROUND AND OBJECTIVE: In recent years, meningitis caused by methicillin-resistant S. aureus has increased. This study was undertaken to compare the clinical characteristics and prognosis of methicillin-resistant S. aureus (MRSA) postneurosurgical meningitis and methicillin-sensible S. aureus (MSSA) postneurosurgical meningitis.
PATIENTS AND METHODS: Twenty-five episodes of postneurosurgical meningitis due to S. aureus (13 methicillin-resistant strains) seen during a ten-year period were retrospectively reviewed.
RESULTS: Most common underlying diseases were: intracerebral hemorrhage (50% of MRSA patients and 46% of MSSA patients) and neoplasm (53% of MRSA patients and 33% of MSSA patients). Eleven patients (6 of them with MRSA infection) had received antibiotic treatment previously. Thirteen patients were carriers of intraventricular catheters (8 with MRSA infection), 5 wore a ventriculoperitoneal shunt (4 with infections by MSSA), 5 cases had a CSF leakage (4 with infections by MRSA), and one patient with infection by MSSA wore an epidural catheter. Fifteen patients were cured (7 with MRSA infection), and 8 died due to the infection (27% with MSSA infection and 38% with MRSA infection).
CONCLUSIONS: The prognosis of postneurosurgical meningitis by S. aureus does not depend on the presence of resistance to methicillin. Nowadays, the intravenous administration of vancomycin is the treatment of choice in MRSA meningitis.
