Daptomycin for the treatment of acute bacterial meningitis: A narrative review

Abstract

There is growing interest in the utilization of daptomycin for the treatment of multi-drug-resistant, Gram-positive infections. Pharmacokinetic studies suggest that daptomycin could penetrate into the cerebrospinal fluid, albeit to a small extent. The objective of this review was to evaluate the available clinical evidence for the use of daptomycin in acute bacterial meningitis of both paediatric and adult patients. Electronic databases were searched up to June 2022 for studies published on the topic. The inclusion criteria were met if the study reported the use of intravenous daptomycin (more than a single dose) for the treatment of diagnosed acute bacterial meningitis. In total, 21 case reports were identified that met the inclusion criteria. These suggest that daptomycin could be a safe and effective alternative to achieve clinical cure of meningitis. In these studies, daptomycin was used in the event of treatment failure, patient intolerance or bacterial resistance to first-line agents. Daptomycin has potential to be an alternative to standard care for meningitis caused by Gram-positive bacteria in the future. However, more robust research is required to establish an optimal dosing regimen, duration of therapy, and place in therapy for the management of meningitis.
