STUDY OBJECTIVE: To determine the safety of daptomycin administered using a variety of doses and dosing frequencies in patients receiving intermittent hemodialysis who had probable or confirmed gram-positive infections.
DESIGN: Analysis of data from the Cubicin Outcomes Registry and Experience (CORE), a multicenter, retrospective, observational registry.
SETTING: Fifty-four study sites, mostly (46%) large teaching hospitals.
PATIENTS: Three hundred ninety-three adults in the CORE registry who received intermittent hemodialysis between 2005 and 2008.
MEASUREMENTS AND MAIN RESULTS: The CORE registry is noninterventional and collects standard-of-care data on daptomycin treatment from health care institutions. Of the 393 patients, 370 (94%) could be categorized by daptomycin dosing frequency: every 48 hours (251 patients [64%]), 3 times/week (87 [22%]), and every 24 hours (32 [8%]); the remaining 23 (6%) had unreported dosing frequencies or received a single dose of daptomycin. Three hundred eighty-four patients (98%) received part of their daptomycin therapy as an inpatient and 129 patients (33%) received part of their daptomycin therapy in an intensive care setting. The primary infection type was bacteremia (224 patients [57%]), and the most common pathogen was Staphylococcus aureus (155 patients [39%]). Thirty-eight adverse events possibly related to daptomycin occurred in 28 patients (7%); increased blood creatine kinase level (7 patients [1.8%]) was the most common adverse event. Adverse-event rates were similar across all dosing regimens.
CONCLUSION: In these patients undergoing hemodialysis, daptomycin was a well-tolerated treatment for gram-positive infections across several doses and dosing frequencies. Further study in prospective trials is warranted.
