This study was performed to evaluate the impacts of vanA positivity of Enterococcus faecium exhibiting diverse susceptibility phenotypes to glycopeptides on clinical outcomes in patients with a bloodstream infection (BSI) through a prospective, multicenter, observational study. A total of 509 patients with E. faecium BSI from eight sentinel hospitals in South Korea during a 2-year period were enrolled in this study. Risk factors of the hosts and causative E. faecium isolates were assessed to determine associations with the 30-day mortality of E. faecium BSI patients via multivariable logistic regression analyses. The vanA gene was detected in 35.2% (179/509) of E. faecium isolates; 131 E. faecium isolates exhibited typical VanA phenotypes (group vanA-VanA), while the remaining 48 E. faecium isolates exhibited atypical phenotypes (group vanA-atypical), which included VanD (n = 43) and vancomycin-variable phenotypes (n = 5). A multivariable logistic regression indicated that vanA positivity of causative pathogens was independently associated with the increased 30-day mortality rate in the patients with E. faecium BSI; however, there was no significant difference in survival rates between the patients of the vanA-VanA and vanA-atypical groups (log rank test, P = 0.904). A high 30-day mortality rate was observed in patients with vanA-positive E. faecium BSIs, and vanA positivity of causative E. faecium isolates was an independent risk factor for early mortality irrespective of the susceptibility phenotypes to glycopeptides; thus, intensified antimicrobial stewardship is needed to improve the clinical outcomes of patients with vanA-positive E. faecium BSI.
