BACKGROUND The relevance of vancomycin resistance in enterococcal blood stream infections (BSI) is still controversial. Aim of this study was to outline the effect of vancomycin resistance of Enterococcus faecium on the outcome of patients with BSI after orthotopic liver transplantation (OLT). METHODS The outcome of OLT recipients developing BSI with vancomycin-resistant (VRE) versus vancomycin-susceptible Enterococcus faecium (VSE) was compared based on data extraction from medical records. Multivariate regression analyses identified risk factors for mortality and unfavourable outcomes (defined as death or prolonged intensive care stay) after 30 and 90 days. RESULTS Mortality was similar between VRE- (n = 39) and VSE- (n = 138) group after 30 (p = 0.44) or 90 days (p = 0.39). Comparable results occurred regarding unfavourable outcomes. Mean SOFANon-GCS score during the 7-day-period before BSI onset was the independent predictor for mortality at both timepoints (HR 1.32; CI 1.14-1.53; and HR 1.18; CI 1.08-1.28). Timely appropriate antibiotic therapy, recent ICU stay and vancomycin resistance did not affect outcome after adjusting for confounders. CONCLUSION Vancomycin resistance did not influence outcome among patients with Enterococcus faecium bacteraemia after OLT. Only underlying severity of disease predicted poor outcome among this homogenous patient population. TRIAL REGISTRATION This study was registered at the German clinical trials register (DRKS-ID: DRKS00013285).

万古霉素耐药性会增加原位肝移植后粪肠球菌菌血症的死亡率吗?回顾性研究。

背景技术在肠球菌血流感染(BSI)中对万古霉素耐药的相关性仍存在争议。这项研究的目的是概述原肠肝移植(OLT)后粪便肠球菌对万古霉素的耐药性对BSI患者预后的影响。方法根据从病历中提取的数据,比较了OLT接受者发展出具有万古霉素耐药性(VRE)与万古霉素敏感性肠球菌(VSE)的BSI的结果。多元回归分析确定了30天和90天后的死亡率和不良结局(定义为死亡或长期重症监护病房)的危险因素。结果在30天(p = 0.44)或90天(p = 0.39)后,VRE-(n = 39)和VSE-(n = 138)组的死亡率相似。就不利的结果发生了可比较的结果。BSI发作前7天期间的平均SOFANon-GCS得分是两个时间点死亡率的独立预测因子(HR 1.32; CI 1.14-1.53​​; HR 1.18; CI 1.08-1.28)。调整混杂因素后,及时进行适当的抗生素治疗,近期入住ICU和万古霉素耐药性均不会影响预后。结论万古霉素耐药对OLT术后粪肠球菌菌血症患者的预后没有影响。只有潜在的疾病严重程度预示了这一同质患者人群的不良结果。试验注册本研究已在德国临床试验注册处注册(DRKS-ID:DRKS00013285)。校正混杂因素后,近期ICU停留时间和万古霉素耐药性均未影响预后。结论万古霉素耐药对OLT术后粪肠球菌菌血症患者的预后没有影响。只有潜在的疾病严重程度预示了这一同质患者人群的不良结果。试验注册本研究已在德国临床试验注册处注册(DRKS-ID:DRKS00013285)。校正混杂因素后,近期ICU停留时间和万古霉素耐药性均未影响预后。结论万古霉素耐药对OLT术后粪肠球菌菌血症患者的预后没有影响。只有潜在的疾病严重程度预示了这一同质患者人群的不良结果。试验注册本研究已在德国临床试验注册处注册(DRKS-ID:DRKS00013285)。
