Staphylococcal CNS infections treated with vancomycin and rifampin

Area of Science:

• Infectious Diseases
• Pediatric Neurology
• Pharmacology

Background:

• Staphylococcal infections of the central nervous system (CNS) pose a significant therapeutic challenge, particularly when caused by methicillin-resistant strains.
• Limited effective treatment options exist for severe CNS staphylococcal infections, necessitating exploration of combination therapies.

Observation:

• Three pediatric cases of CNS staphylococcal infections were analyzed.
• Two of these infections involved methicillin-resistant Staphylococcus organisms.
• Initial treatment with vancomycin hydrochloride alone was unsuccessful in one patient.

Findings:

• Combination therapy with vancomycin hydrochloride and rifampin demonstrated prompt clinical and bacteriologic resolution in all three pediatric cases.
• Satisfactory rifampin levels were achieved via oral or intravenous administration.
• Oral rifampin achieved high concentrations in subdural pus, exceeding minimal bactericidal levels.

Implications:

• Vancomycin and rifampin combination therapy is a recommended treatment strategy for staphylococcal CNS infections in children.
• This combination offers a viable option for managing infections caused by methicillin-resistant Staphylococcus.
• Further research into optimal dosing and efficacy of this combination in pediatric CNS infections is warranted.
