BackgroundInfections caused by vancomycin-resistant Enterococcus faecium (VRE) are a major cause of morbidity and mortality in the liver transplant population. Daptomycin (DAP) is often used to treat infections caused by VRE, but DAP nonsusceptibility in Enterococcus is increasing. MethodPatients with DAP-nonsusceptible Enterococcus (DNSE) infections who had undergone liver transplantation between January 1, 2010 and July 31, 2014 were retrospectively reviewed. A convenience sample of DNSE isolates was analyzed by pulsed-field gel electrophoresis (PFGE). ResultsWe identified 14 liver transplant recipients (LTRs) who developed DNSE infections post transplantation. Postoperative complications were common, and most patients required repeat abdominal surgery within 90 days of transplantation. The initial DNSE culture was taken a median of 74.5 days post transplant and was secondary to an intra-abdominal infection in all but 1 patient. Half of patients were VRE colonized before or at the time of organ transplantation, and all those who were not VRE colonized at the time of transplantation later became colonized, a median of 27 days post transplant. Overall mortality in this cohort was 71%. PFGE did not demonstrate genetic relatedness among DNSE isolates. ConclusionThis study, the largest published series to our knowledge of DNSE infections in LTRs, demonstrates that these infections occur in patients with serious surgical complications and are associated with high morbidity and mortality. Established risk factors for VRE infection were common, as was DAP exposure. Although many risk factors for DNSE infection cannot be changed, this case series identifies several potentially modifiable variables. Further work is needed to identify interventions to decrease the risk of developing DNSE infections in this complex patient population.
