Use of daptomycin for the treatment of methicillin-resistant coagulase-negative staphylococcal ventriculitis

Area of Science:

• Infectious Diseases
• Neuroscience
• Pharmacology

Background:

• Coagulase-negative staphylococci (CoNS) are primary pathogens in hospital-acquired external-ventricular-drain (EVD) and lumbar-drain (LD) associated meningitis and ventriculitis.
• Treatment for these central nervous system (CNS) infections is challenging, often necessitating combined intraventricular and intravenous antibiotic administration.
• Limited data exist on daptomycin's efficacy in CNS infections, though animal studies suggest good penetration and bactericidal activity.

Observation:

• This report details the clinical experience of treating a specific case of an EVD-related infection.
• The study focuses on the use of daptomycin, an antibiotic with demonstrated activity against CoNS.

Findings:

• Daptomycin exhibits rapid bactericidal activity.
• The antibiotic demonstrates adequate penetration into inflamed meninges.
• Daptomycin has an extended half-life within the ventricles.

Implications:

• Further clinical investigation into daptomycin for CNS infections is warranted.
• Daptomycin may represent a viable therapeutic option for EVD/LD-associated meningitis and ventriculitis.
• This case contributes to the limited clinical data on daptomycin use in CNS infections.
