Recently, three epidemics in Dutch hospitals were caused by vancomycin-resistant enterococci (VRE). Although the number of infections was small, spread of colonization was extensive and many infection control measures were necessary to prevent further spread. VRE are relatively avirulent bacteria. However, few, if any, antibiotics are available for treatment of infections caused by VRE and the genetic code for resistance may be transferable to other, more virulent, bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA). Although colonization and infection with MRSA have become endemic in many surrounding countries, such a situation has been prevented in the Netherlands by employing an aggressive 'search and destroy' policy. Although many questions regarding the optimal approach of VRE remain unanswered, a similar policy as employed for MRSA will not be possible. In contrast to MRSA, colonization with VRE occurs in the open population, no populations with increased risk for colonization appear to be definable and colonization cannot be eradicated. Based on common sense, a differentiated approach seems indicated in which extensive infection control measures should only be implemented when spread of a single genotype has been demonstrated. A reference laboratory should be created for uniform genotyping.
最近,荷兰医院发生的三起疫情是由耐万古霉素肠球菌(VRE)引起的。尽管感染数量不多,但定植传播广泛,需要采取许多感染控制措施以防止进一步传播。VRE是相对无毒力的细菌。然而,治疗VRE引起的感染可用的抗生素很少,即便有也寥寥无几,而且耐药基因编码可能会转移到其他毒性更强的细菌,如耐甲氧西林金黄色葡萄球菌(MRSA)。尽管在许多周边国家,MRSA的定植和感染已变得很普遍,但荷兰通过采取积极的“搜索并消灭”政策避免了这种情况的发生。尽管关于VRE的最佳应对方法仍有许多问题未得到解答,但采用与MRSA相同的政策是不可能的。与MRSA不同,VRE在普通人群中发生定植,似乎无法确定定植风险增加的人群,而且定植无法根除。基于常识,似乎需要采取一种差异化的方法,即只有在证明单一基因型传播时才应实施广泛的感染控制措施。应设立一个参考实验室进行统一的基因分型。
