头孢他啶/阿维巴坦治疗耐碳青霉烯类肺炎克雷伯菌感染的研究进展

近年来,耐碳青霉烯类肺炎克雷伯菌(CRKP)感染的流行已成为全球公共卫生问题。头孢他啶/阿维巴坦(CAZ/AVI)作为一种新型的抗菌药物已批准用于治疗医院获得性肺炎/呼吸机相关肺炎、血流感染、肾移植术后感染和肝硬化合并严重感染。然而,随着CAZ/AVI的使用,CAZ/AVI耐药菌株也随之产生。CAZ/AVI主要耐药机制为blaKPC基因过表达、产β-内酰胺酶及关键位点氨基酸的突变、膜孔蛋白丢失导致的细胞通透性改变和外排泵的过表达。本文将对CAZ/AVI在治疗CRKP感染方面的研究进展进行综述,为临床诊断和治疗提供参考依据。
Advances of ceftazidime/avibactam in the treatment of carbapenem-resis-tant Klebsiella pneumoniae infection
In recent years,the prevalence of carbapenem-resistant Klebsiella pneumoniae(CRKP)infection has become a global public health issue.Ceftazidime/avibactam(CAZ/AVI)has been approved as a novel antimicrobial agent for the treatment of healthcare-associated pneumonia/ventilator-associated pneumonia,bloodstream infection,infection after kidney transplantation,and severe infection combined with liver cirrhosis.However,the use of CAZ/AVI has also led to the emergence of drug-resistant strains.The major mechanisms of drug-resistance include over-expression of blaKPC gene,mutation of β-lactamase and amino acids at key sites,changes in cell permeability caused by loss of membrane porin,and over-expression of efflux pump.This article reviews the research progress of CAZ/AVI in the treatment of CRKP infection,providing reference for clinical diagnosis and treatment.
