INTRODUCTION: Daptomycin doses 8-12 mg/kg are recommended for susceptible dose-dependent Enterococcus species. However, data remain limited on safety outcomes of such dosing, compared to standard 4-6 mg/kg dosing.
METHODS: In this retrospective cohort study, patients were stratified into daptomycin standard-dose (≤ 6.5 mg/kg) versus high-dose (≥ 7.5 mg/kg) groups. The primary outcome was daptomycin safety based on a composite of creatine kinase elevation, daptomycin-related peripheral blood eosinophilia, eosinophilic pneumonitis, alanine aminotransferase elevation, and alkaline phosphatase elevation. A secondary aim was to identify risk factors for daptomycin adverse effects. Inclusion criteria were age ≥ 18 years old, daptomycin receipt for ≥ 48 h, and Enterococcus cultures with a daptomycin minimal inhibitory concentration 2-4 mg/L.
RESULTS: A total of 119 patients were included for analysis. Median daptomycin doses were 6.0 mg/kg (IQR 5.4, 6.1) and 8.1 mg/kg (IQR 7.9, 9.6) in the standard- and high-dose cohorts, respectively. Median durations were 13.5 days (standard-dose) and 16 days (high-dose) (p = 0.02). The composite safety endpoint occurred in 32.0% of the standard-dose group and 32.5% of the high-dose group (p = 0.96). Daptomycin was dose-reduced or held in 8.1% of patients experiencing an adverse effect. Concurrent antihistamine usage was associated with the composite outcome; however, there was no association with daptomycin dose or concurrent statin use.
CONCLUSION: High-dose daptomycin was not associated with increased laboratory abnormalities or adverse drug reactions compared to standard-dose daptomycin.
