Carbapenem-resistant Enterobacteriaceae (CRE) have emerged as a major threat. Commonly used antibiotics are generally inactive against CRE. Therefore, timely detection of CRE is of paramount importance. Among CRE, those producing carbapenem-hydrolyzing β-lactamase enzymes (carbapenemase-producing Enterobacteriaceae) are particularly of concern because they tend to spread, and treatment is difficult. The carbapenemase groups most commonly encountered include KPC, NDM, and OXA-48. Treatment options are limited and include combinations of polymyxins, tigecycline, aminoglycosides, or carbapenems; newer agents with activity against CRE and better safety profiles are becoming available and will likely emerge as the preferred therapy.
耐碳青霉烯类肠杆菌科细菌(CRE)已成为一个重大威胁。常用抗生素通常对CRE无活性。因此,及时检测CRE至关重要。在CRE中,那些产生碳青霉烯水解β-内酰胺酶的细菌(产碳青霉烯酶肠杆菌科细菌)尤其令人担忧,因为它们易于传播且治疗困难。最常见的碳青霉烯酶类别包括KPC、NDM和OXA-48。治疗选择有限,包括多黏菌素、替加环素、氨基糖苷类或碳青霉烯类药物的联合使用;对CRE有活性且安全性更好的新型药物正在出现,并可能成为首选治疗方法。
