          摘  要  目的  系统评价多黏菌素 B 治疗碳青霉烯类耐药革兰阴性菌(CR-GNB)感染者全因死亡的影响因素。方法  检索
          PubMed、Embase、The Cochrane Library、Web of Science、万方、维普、中国生物医学文献数据库和中国知网,收集多黏菌素 B 治疗
          CR-GNB感染者30 d内或28 d内全因死亡的临床报道,检索期限为数据库建库至2025年7月。筛选文献、提取数据、评价文献质
          量后,采用 RevMan 5.4 软件进行 Meta 分析。结果  共纳入 12 篇文献,涉及 1 326 例患者,其中死亡患者为 529 例,死亡率为
          39.89%。Meta 分析结果显示,合并心血管疾病[OR=2.06,95%CI(1.37,3.09),P=0.005]、序贯器官衰竭评估(SOFA)评分升高
          [OR=1.20,95%CI(1.07,1.35),P=0.003]、机械通气[OR=2.35,95%CI(1.65,3.34),P<0.001]、连续性肾脏替代治疗(CRRT)
          [OR=2.58,95%CI(1.67,3.97),P<0.001]、血流感染[OR=3.24,95%CI(2.19,4.78),P<0.001]、多部位感染[OR=1.51,95%CI
         (1.03,2.20),P=0.03]、感染性休克[OR=3.19,95%CI(1.94,5.24),P<0.001]、使用血管活性药物[OR=2.90,95%CI(1.97,4.27),
          P<0.001]、发生急性肾损伤(AKI)[OR=2.17,95%CI(1.41,3.36),P<0.001]是多黏菌素B治疗CR-GNB感染者全因死亡的危险因
          素,多黏菌素 B 用药疗程延长[OR=0.92,95%CI(0.86,0.99),P=0.03]和 CR-GNB 感染后早期用药[OR=0.47,95%CI(0.25,
          0.85),P=0.01]是保护因素。结论  合并心血管疾病,接受机械通气或CRRT,发生血流感染、多部位感染、感染性休克,合并使用
          血管活性药物,出现AKI且SOFA评分升高的CR-GNB感染者,全因死亡风险较高;而延长多黏菌素B用药疗程(>7 d)、在确诊
          CR-GNB感染后48 h内早期给药,可显著降低该类患者的全因死亡风险。

          Meta-analysis  of  influential  factors  for  all-cause  mortality  in  patients  with  carbapenem-resistant  Gram-
          negative bacteria treated with polymyxin B

          ABSTRACT   OBJECTIVE  To  systematically  evaluate  the  influential  factors  for  all-cause  mortality  in  patients  with  carbapenem-
          resistant Gram-negative bacteria (CR-GNB) treated with polymyxin B. METHODS PubMed, Embase, the Cochrane Library, Web
          of Science, Wanfang Data, VIP, CBM and CNKI were searched to collect clinical studies on all-cause death within 30 days or 28
          days after treatment with polymyxin B in patients with CR-GNB infection from database establishment to July 2025. After literature
          screening, data extraction and evaluation of literature quality, meta-analysis was performed using RevMan 5.4 software. RESULTS
          A  total  of  12  studies  were  included,  involving  1  326  patients,  among  whom  529  patients  died,  with  a  mortality  rate  of  39.89%.
          Meta-analysis  results  showed  that  combined  with  cardiovascular  disease  [OR=2.06,  95%CI (1.37,  3.09),  P=0.005],  increased
          Sequential  Organ  Failure Assessment (SOFA)  score  [OR=1.20,  95%CI (1.07,  1.35),  P=0.003],  mechanical  ventilation  [OR=
          2.35,  95%CI (1.65,  3.34),  P<0.001],  continuous  renal  replacement  therapy (CRRT)  [OR=2.58,  95%CI (1.67,  3.97),  P<
          0.001],  bloodstream  infection  [OR=3.24,  95%CI (2.19,  4.78),  P<0.001],  multiple-site  infection  [OR=1.51,  95%CI (1.03,
          2.20),  P=0.03],  septic  shock  [OR=3.19,  95%CI (1.94,  5.24),  P<0.001],  use  of  vasoactive  drugs  [OR=2.90,  95%CI (1.97,
          4.27), P<0.001], and the occurrence of acute kidney injury (AKI) [OR=2.17, 95%CI (1.41, 3.36), P<0.001] were risk factors
          for  all-cause  mortality  in  patients  with  CR-GNB  infection  treated  with  polymyxin  B.  Conversely,  an  extended  duration  of
          polymyxin  B  treatment  [OR=0.92,  95%CI (0.86,  0.99),  P=0.03]  and  early  administration  after  CR-GNB  infection  [OR=0.47,
          95%CI (0.25,  0.85),  P=0.01]  were  protective  factors.  CONCLUSIONS  Patients  with  cardiovascular  disease,  receiving
          mechanical  ventilation  or  CRRT,  having  bloodstream  infection,  multiple-site  infection  or  septic  shock,  combining  with  vasoactive
          drugs,  with  AKI  and  increased  SOFA  scores  have  a  higher  risk  of  all-cause  mortality.  Conversely,  extending  the  duration  of
                                                             polymyxin  B  treatment  (beyond  7  days)  and  early
                                                             administration  within  48  hours  after  confirmed  CR-GNB
