Daptomycin is a lipopeptide antibiotic with rapid bactericidal activity against Gram-positive bacteria. Reports regarding the use of daptomycin in infants are still limited. Thus, the objective of this report is to describe the safety and efficacy of daptomycin in premature infants with persistent coagulase-negative staphylococci (CoNS) infection.


This was a retrospective chart review of 10 premature infants with persistent CoNS infection who received daptomycin therapy between January 2018 and September 2019. Four patients had endocarditis and 1 had bacterial meningitis and infectious endocarditis. The other 5 patients had persistent CoNS bacteraemia only.


Daptomycin treatment was successful for 5 patients. The others died owing to multiple factors such as prematurity, sepsis, and chronic lung disease. Adverse drug reactions, including elevation of creatine phosphokinase and/or hepatotoxicity, were noted in 4 patients.


Large and randomized studies are necessary to ensure daptomycin's safety and efficacy for the treatment of infants with persistent sepsis caused by Gram-positive bacteria.
