          摘   要  目的  比较头孢他啶阿维巴坦(CZA)单药与联合疗法用于碳青霉烯类耐药革兰氏阴性菌(CRGNB)感染的疗效,并分析
          其影响因素。方法  回顾性收集2020年1月至2025年3月在我院接受CZA治疗的CRGNB 感染的患者资料,按用药的不同分为
          CZA单药组(52例)与CZA联合组(85例)。比较两组患者的疗效,记录分离菌株的药敏试验结果;采用多因素Logistic回归模型
          分析影响CRGNB感染患者临床疗效的因素。结果  CZA联合组患者的细菌清除率显著高于CRZ单药组(P=0.012),但两组患者
          的30 d病死率及临床有效率比较,差异均无统计学意义(P>0.05)。耐碳青霉烯类肺炎克雷伯菌对替加环素敏感率最高(87.3%),
          耐碳青霉烯类铜绿假单胞菌对阿米卡星的敏感率为90.9%;5株分离菌株对CZA耐药。多因素Logistic回归分析结果显示,发生肺部
          感染、接受连续性肾脏替代治疗(CRRT)、疗程不足与临床治疗失败显著相关(P<0.05)。结论  CZA联合疗法与单药治疗CRGNB感
          染的临床有效率相当,但联合疗法的细菌清除率更高。发生肺部感染、接受CRRT以及疗程不足是临床治疗失败的独立危险因素。

          ABSTRACT    OBJECTIVE  To compare the efficacy of ceftazidime and avibactam (CZA) monotherapy and combination therapy
          in  the  treatment  of  carbapenem-resistant  Gram-negative  bacteria (CRGNB)  infections,  and  analyze  the  influencing  factors.
          METHODS  The  data  of  patients  with  CRGNB  infection  who  received  CZA  treatment  from  January  2020  to  March  2025  were
          collected retrospectively. The patients were divided into the CZA monotherapy group (52 cases) and the CZA combination therapy
          group (85  cases)  according  to  treatment  regimen.  The  therapeutic  effects  of  the  two  groups  were  compared,  and  the  drug
          susceptibility  results  of  isolated  strains  were  recorded.  The  multivariate  Logistic  regression  model  was  used  to  analyze  the  factors
          influencing  clinical  efficacy  of  CRGNB  patients.  RESULTS  The  bacterial  clearance  rate  of  patients  was  significantly  higher  in  the
          CZA combination therapy group than in the CZA monotherapy group (P=0.012). However, when comparing the 30-day mortality
          rate and the clinical response rate between the two groups, no statistically significant differences were observed (P>0.05). Among
          the isolates, carbapenem-resistant Klebsiella pneumoniae had the highest sensitivity to tigecycline (87.3%) and carbapenem-resistant
          Pseudomonas  aeruginosa  showed  90.9%  sensitivity  to  amikacin.  Five  isolates  were  resistant  to  CZA.  The  multivariate  Logistic
          regression showed, lung infection, receiving continuous renal replacement therapy (CRRT), and inadequate treatment courses were
          significantly  correlated  with  clinical  treatment  failure (P<0.05).  CONCLUSIONS  For  CRGNB  infection,  the  clinical  efficacy  of
          CZA combination therapy is similar to that of monotherapy, but the combination therapy has a higher bacterial clearance rate. Lung
                                                              infections,  receiving  CRRT  and  inadequate  treatment  courses
