Leuk Lymphoma:达托霉素治疗万古霉素耐药的肠球菌血流感染:风险因素和结局

2017-08-14 吴刚 环球医学

达托霉素常用作血液系统恶性肿瘤患者万古霉素耐药的肠球菌(VRE)血流感染(BSI)的治疗选择,但是越来越多的研究报道了达托霉素不敏感的VRE。2017年12月,发表在《Leuk Lymphoma》的一项研究调查了血液系统恶性肿瘤患者中,达托霉素不敏感的VRE血流感染的风险因素和结局。



达托霉素常用作血液系统恶性肿瘤患者万古霉素耐药的肠球菌(VRE)血流感染(BSI)的治疗选择,但是越来越多的研究报道了达托霉素不敏感的VRE。2017年12月,发表在《Leuk Lymphoma》的一项研究调查了血液系统恶性肿瘤患者中,达托霉素不敏感的VRE血流感染的风险因素和结局。

研究人员回顾了血液系统恶性肿瘤患者中,达托霉素不敏感的VRE BSI的经历。研究人员比较了20例达托霉素不敏感的VRE BSI(病例患者)与40例达托霉素敏感的VRE BSI配对对照患者的风险因素和结局。

结果显示,病例患者具有更多的并发症(6/20 vs 2/40,P=0.013),两组全因死亡率相似。多变量分析显示,仅有90天内既往达托霉素暴露与达托霉素不敏感的VRE BSI显着相关(比值比,26.71;P<0.0001)。25%的病例患者中,VRE分离株的初始最小抑菌浓度(MIC)为4μg/mL的所有患者在治疗期间都出现了不敏感,这对较高剂量的达托霉素是否可用于血液系统恶性肿瘤患者VRE BSI的治疗提出了质疑。
