Carbapenem-resistant Klebsiella pneumoniae (CRKP) is an increasing global threat. Here, we describe the prevalence and impact of tigecycline use in a cohort of patients with CRKP bacteriuria nested within a multicentre, prospective study. In the 21-month study period, 260 unique patients were included. Tigecycline was given to 80 (31%) patients. The use of tigecycline during the index hospitalization was significantly associated with the subsequent development of tigecycline resistance in the same patient (OR, 6.13; 95% CI, 1.15-48.65; p 0.03). In conclusion, the use of tigecycline with CRKP bacteriuria is common, and is associated with the subsequent development of tigecycline resistance.
耐碳青霉烯类肺炎克雷伯菌(CRKP)对全球的威胁日益增大。在此,我们在一项多中心前瞻性研究中,描述了替加环素在一组CRKP菌尿症患者中的使用情况及其影响。在为期21个月的研究期间,共纳入了260例不同患者。80例(31%)患者接受了替加环素治疗。在首次住院期间使用替加环素与同一患者随后出现替加环素耐药性显著相关(比值比,6.13;95%置信区间,1.15 - 48.65;P = 0.03)。总之,在CRKP菌尿症患者中使用替加环素很常见,且与随后出现替加环素耐药性有关。
