DEL ROSARIO-GARCIA, Betel et al. Vancomycin versus daptomycin for the treatment of confirmed gram-positive catheter-related bloodstream infections in oncology patients. Farm Hosp. [online]. 2022, vol.46, n.3, pp.105-108.  Epub July 11, 2022. ISSN 2171-8695.


To analyse the effectiveness and safety of daptomycin versus vancomycin on the management catheter-related bloodstream infections in oncology patients.


A retrospective study was carried out including all patients admitted at the Medical Oncology Unit between 2010 and 2018 with positive blood cultures confirmed catheter-related bloodstream infections due to gram-positive microorganism, who were treated with either vancomycin or daptomycin. The primary end point was all cause 30-days mortality, 30-days hospital readmission and length of hospital stay (length of hospital stay).


A total of 70 patients with catheter-related bloodstream infections were included in the present study: vancomycin was administered to 61.4% (n = 43) and daptomycin to 38.6% (n = 27) of patients. 78.5% (n = 55) of isolated bacteria showed a vancomycin mínimum inhibitory concentration ≤ 1 μg/ml. No differences were observed between the two groups of patients regarding the 30-day mortality rate rate (32.6% [n = 14] versus 29.6% [n = 8]; p = 0.797), the 30-day re-admission rate (30.2% [n = 13] versus 29.6% [n = 8]; p = 0.957) or the length of hospital stay (18.9 versus 16.5 days; p = 0.562). Nephrotoxicity rate was equivalent in both groups: a 7% (n = 3) of vancomycin goup versus a 7.4% (n = 2) of daptomycin group (p = 0.946).


Our results show that both antibiotics are equivalent in their safety and effectiveness. Therefore, vancomycin should continue being the treatment of chose for gram-positive catheter-related bloodstream infections, in particular at hospital centres with a low prevalence of strains that show diminished susceptibility to vancomycin.
