COMPARATIVE STUDY
JOURNAL ARTICLE
Comparison of risk factors and outcomes of daptomycin-susceptible and -nonsusceptible vancomycin-resistant Enterococcus faecium infections in liver transplant recipients.
BACKGROUND: Vancomycin-resistant Enterococcus faecium (VRE) infections are common in liver transplant recipients (LTRs). Daptomycin (DAP) is an important treatment for such infections; however, DAP-nonsusceptible VRE (DNS-VRE) are increasingly frequent. The purpose of this study was to compare clinical characteristics and outcomes of LTRs with infections due to DNS-VRE and DAP-susceptible VRE (DS-VRE).
METHODS: A single center, retrospective review of patients who underwent liver transplantation between January 1, 2010 and December 31, 2015 and developed infections due to DS-VRE or DNS-VRE post transplant was performed. Patients with DNS-VRE and DS-VRE infections were compared using univariate and logistic regression analysis.
RESULTS: Fourteen LTRs developed DNS-VRE and 20 LTRs developed DS-VRE infection post-transplantation. No significant differences were observed in demographics, model for end-stage liver disease (MELD) scores, causes of end-stage liver disease, or rate of pre-transplant perirectal VRE colonization between groups. Bleeding complications and renal replacement therapy were more common in the DNS-VRE group than in the DS-VRE group. The duration of transplant hospitalization and post-transplant intensive care unit (ICU) admission was longer in the DNS-VRE group than in the DS-VRE group. The 30-day and 6-month mortality rate associated with DNS-VRE infection was similar to that associated with DS-VRE infection.
CONCLUSIONS: Liver transplant recipients who develop DNS-VRE infection have higher bleeding complications and longer, more complex hospitalizations compared to those who develop DS-VRE infection post transplantation; however, mortality at 30 days and 6 months is not significantly worse. Further study is needed to determine optimal strategies for the prevention and treatment of DNS-VRE infections in LTRs.
