    • 摘要: 目的 探讨儿童碳青霉烯类肠杆菌科细菌(CRE)感染与临床抗菌药物使用的相关性。方法 回顾性分析徐州市儿童医院2022年10月—2024年12月收治的住院患儿临床资料(根据样本量估算公式,估算需117例,最终符合纳入标准100例)。对所有患儿检测样本进行CRE检测及常用抗菌药物药敏试验,观察分离菌株类型与耐药性结果。结果 共检出100株CRE菌株,其中肺炎克雷伯菌50株(50.00%)、大肠埃希菌31株(31.00%)、阴沟肠杆菌11株(11.00%)为主要菌株;肺炎克雷伯菌对亚胺培南、美罗培南、头孢噻肟、头孢曲松、氨苄西林耐药率均达100%;对四环素、环丙沙星、头孢替坦、庆大霉素分别为88.00%、80.00%、78.00%、76.00%。大肠埃希菌对亚胺培南、美罗培南、头孢噻肟、头孢曲松耐药率达100%;对环丙沙星、头孢替坦、氨苄西林、左氧氟沙星分别为83.87%、74.19%、74.19%、70.97%。阴沟肠杆菌对头孢噻肟、头孢曲松耐药率达100%,对氨苄西林达72.73%。结论 儿童临床CRE感染主要致病菌为肺炎克雷伯菌、大肠埃希菌、阴沟肠杆菌,肺炎克雷伯菌与大肠埃希菌对临床常用抗菌药耐药性较高,阴沟肠杆菌对头孢噻肟、头孢曲松耐药性突出。

       

      Abstract: Objective To investigate the relationship between carbapenem-resistant Enterobacterales (CRE) infections in children and clinical antibacterial drug use. Methods Hospitalized children who were admitted to Xuzhou Children's Hospital from October 2022 to December 2024 were selected and their clinical data were retrospectively analyzed. (Based on the sample size estimation formula, the estimated required sample size was 117 cases; finally, 100 cases met the inclusion criteria.) All specimens were tested for CRE, and antimicrobial susceptibility testing was performed for commonly used antibacterial agents. The types of isolated strains and their resistance profiles were analyzed. Results A total of 100 CRE isolates were identified, with Klebsiella pneumoniae (50 isolates, 50.00%), Escherichia coli (31 isolates, 31.00%), and Enterobacter cloacae (11 isolates, 11.00%) as the predominant organisms. K. pneumoniae showed 100% resistance to imipenem, meropenem, cefotaxime, ceftriaxone, and ampicillin; resistance rates to tetracycline, ciprofloxacin, cefotetan, and gentamicin were 88.00%, 80.00%, 78.00%, and 76.00%, respectively. E. coli exhibited 100% resistance to imipenem, meropenem, cefotaxime, and ceftriaxone; resistance rates to ciprofloxacin, cefotetan, ampicillin, and levofloxacin were 83.87%, 74.19%, 74.19%, and 70.97%, respectively. E. cloacae showed 100% resistance to cefotaxime and ceftriaxone, and 72.73% resistance to ampicillin. Conclusions The main pathogens causing clinical CRE infections in children were K. pneumoniae, E. coli, and E. cloacae. K. pneumoniae and E. coli demonstrate high resistance to commonly used antibacterial agents in clinical practice, while E. cloacae showed particularly prominent resistance to cefotaxime and ceftriaxone.
