Vancomycin treatment for enterococcal meningitis
Abstract:
Although clinical disease due to enterococcus is common, there has been only limited experience in the treatment of central nervous system infections by this pathogen. In particular, there have been few reports regarding the treatment of such infections in the penicillin-allergic individual. We present two cases of meningitis due to enterococci, including one case with a brain abscess, in patients with strong histories of penicillin sensitivity. We treated these patients with vancomycin hydrochloride and an aminoglycoside. Vancomycin with an aminoglycoside seems to be a reasonable treatment for enterococcal central nervous system infections.
Insights
Enterococcal central nervous system infections are challenging, especially in penicillin-allergic patients. Vancomycin combined with an aminoglycoside offers a viable treatment option for these serious infections.
Area of Science:
- Infectious Diseases
- Neurology
- Pharmacology
Background:
- Enterococcal infections, particularly those affecting the central nervous system (CNS), are clinically significant but infrequently reported.
- Limited data exists on treating CNS enterococcal infections in patients with penicillin allergies.
Observation:
- Two cases of meningitis caused by enterococci were treated.
- One case involved a concurrent brain abscess.
- Both patients had a documented history of severe penicillin sensitivity.
Findings:
- Treatment with vancomycin hydrochloride and an aminoglycoside was effective in both cases.
- This combination therapy demonstrated success in managing severe enterococcal CNS infections.
Implications:
- Vancomycin and aminoglycoside combination therapy is a recommended approach for enterococcal CNS infections.
- This treatment strategy provides a crucial alternative for penicillin-allergic individuals facing these infections.
