Persistent meningeal inflammation associated with intrathecal gentamicin
The American Journal of the Medical Sciences
|September 1, 1977
Abstract:
A 30-year-old woman was treated with intraventricular gentamicin for Klebsiella meningitis. Cultures became sterile, but meningeal inflammation, associated with high central spinal fluid gentamicin levels, persisted until gentamicin was discontinued.
Insights
Intraventricular gentamicin cleared Klebsiella meningitis, but high drug levels in cerebrospinal fluid caused persistent inflammation. Discontinuing gentamicin resolved the inflammation, highlighting potential neurotoxicity risks.
Area of Science:
- Neuroscience
- Infectious Diseases
- Pharmacology
Background:
- Bacterial meningitis poses significant neurological risks.
- Intraventricular antibiotics are used for severe or refractory cases.
- Gentamicin is an aminoglycoside antibiotic with potential ototoxicity and nephrotoxicity.
Observation:
- A patient with Klebsiella meningitis received intraventricular gentamicin.
- Cerebrospinal fluid cultures became sterile after treatment.
- Persistent meningeal inflammation was noted despite sterile cultures.
Findings:
- High gentamicin concentrations were detected in the cerebrospinal fluid.
- Meningeal inflammation correlated with elevated gentamicin levels.
- Cessation of gentamicin led to the resolution of meningeal inflammation.
Implications:
- High intraventricular gentamicin levels may cause sustained meningeal inflammation.
- Careful monitoring of drug levels and potential neurotoxicity is crucial.
- Alternative or adjunctive therapies may be needed for meningitis treatment.
