Real-world evidence of dalbavancin effectiveness as consolidation therapy in infective endocarditis due to Enterococcus spp

# metadata.dc.description.abstract[].value
Enterococcal endocarditis (EIE) affects elderly patients, with high rates of complications and mortality, and dalbavancin (DBV) exhibits significant antimicrobial activity against most enterococci. However, data are lacking on the use of DBV in EIE. The main objective was to evaluate the outcomes of treatment with DBV in the consolidation therapy of IE by Enterococcus spp. Methods: Spanish-French retrospective observational study of patients with EIE enrolled between November 2016 and June 30, 2022 receiving DBV in consolidation phase and followed for >= 12 months. Results: Ninety-eight patients were enrolled, 69.4 % male, with mean age of 71.2 (+/- 12.51) years and median Charlson index of 5 (IQR 3-7). Criteria for definite IE were met by 84.7%; 60.2 % had IE on native valve, 26.5 % late prosthetic IE, 8.2 % early prosthetic IE, 2 % cardiovascular implantable electronic-IE (CIE-IE), and 3.1 % CIE-IE and valve. Aortic valve involvement was observed in 66.3 %. E. faecalis was isolated in 86.7 %, E. faecium in 11.2%; 32.6% underwent surgery, and these had a higher cure rate (100% vs 75.8 %; p = 0.005) and lower mortality (0 vs 13.6 %; p = 0.029). DBV was administered to facilitate discharge in 88.8 %. Total dose was 2500 mg (1500-3000) over 3.5 weeks (2-4). Loss to follow-up was 0%, relapse rate 8.2 %, 1-year IE-related mortality 3.1 %, and clinical cure rate 81.2 %. Severe adverse events affected 1 % (acute tubular necrosis). Hospital stay was reduced by 21 days (14-28). Conclusions: DBV appears to be highly effective, safe, and cost-effective as consolidation therapy in patients with IE caused by Enterococcus spp., with minimal adverse events.
