Abstract
Purpose
Dalbavancin is a novel lipoglycopeptide with potent activity against several gram-positive pathogens, an excellent safety profile and a long elimination half-life.
Methods
In this case series observed at the University Hospital of Vienna between 2015 and 2017, all adult patients with gram-positive infections who received at least one dosage of dalbavancin were screened (n = 118). A total of 72 patients were included in the final analysis. The number of included patients stratified by the source of infection was: skin and soft tissue infection (SSTI) (n = 26), osteomyelitis (n = 20), spondylodiscitis (n = 14), acute septic arthritis (n = 4) and prosthetic joint infection (n = 8).
Results
In 46 patients (64%), clinical cure was detected at the end of dalbavancin therapy without additional antibiotic therapy. Of the 26 patients who received additional antibiotic therapy other than dalbavancin, 15 patients (21%) showed no clinical improvement under dalbavancin therapy, four patients (5%) had side effects (nausea n = 1, exanthema n = 2, hyperglycemia n = 1), and in seven patients (10%) clinical improvement under dalbavancin therapy was detected but antibiotic therapy was de-escalated to an oral drug.
Conclusion
We demonstrated high clinical effectiveness of dalbavancin for acute gram-positive infections primarily acute SSTI, acute septic arthritis, acute osteomyelitis and spondylodiscitis. In patients with biofilm-associated infection (chronic infection or joint prosthesis), source control was absolutely necessary for treatment success.
