Abstract:
Background The use of intrathecal antibiotic therapy for the treatment of ventriculitis and/or meningitis has demonstrated efficacy especially when sterilization of the cerebrospinal fluid is not possible with intravenous antibiotics alone. Case Description We describe the successful treatment of Enterococcus faecalis ventriculitis utilizing intrathecal linezolid in a 32-year-old female patient with severe allergy to vancomycin, prohibitive bacterial susceptibilities, and failure of previous attempts to sterilize the cerebrospinal fluid despite multimodal treatment. Conclusion Intrathecal linezolid is a useful treatment in the setting of multidrug-resistant bacterial ventriculitis. We present a useful dosing regimen for the administration of intrathecal linezolid.
Insights
Intrathecal linezolid successfully treated a patient with Enterococcus faecalis ventriculitis when other options failed. This study presents a dosing regimen for this effective treatment of drug-resistant bacterial meningitis.
Area of Science:
- Infectious Diseases
- Neuroscience
- Pharmacology
Background:
- Intrathecal antibiotic therapy is effective for ventriculitis and meningitis when intravenous antibiotics fail.
- Cerebrospinal fluid sterilization remains a challenge in complex cases.
- Multidrug-resistant pathogens necessitate novel therapeutic strategies.
Observation:
- A 32-year-old female patient presented with Enterococcus faecalis ventriculitis.
- The patient had a severe allergy to vancomycin and limited antibiotic options.
- Previous treatments failed to sterilize cerebrospinal fluid despite multimodal approaches.
Findings:
- Successful treatment of ventriculitis was achieved using intrathecal linezolid.
- This case highlights the efficacy of intrathecal linezolid in a vancomycin-allergic patient.
- A practical dosing regimen for intrathecal linezolid administration is provided.
Implications:
- Intrathecal linezolid is a viable option for multidrug-resistant bacterial ventriculitis.
- This approach offers a solution for patients with antibiotic allergies.
- The presented dosing regimen can guide clinical practice for intrathecal linezolid use.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
