Abstrakt: A matched 1:2 case-control study was conducted among critically ill patients in order to identify the risk factors of colistin or tigecycline-resistant carbapenemase-producing Klebsiella pneumoniae (ColR-Kp, TigR-Kp) bacteraemia. MIC to colistin and tigecycline were determined by Etest. From 224 bacteraemic patients, 46.4% and 29.5% were resistant to colistin and tigecycline, respectively. PCR revealed that 199 isolates carried the bla KPC gene. PCR revealed that no isolate carried the mcr-1 gene. Risk factors for ColR-Kp bacteraemia as compared to patients with bacteraemia by a colistin-susceptible isolate or patients without carbapenemase-producing K. pneumoniae bacteraemia were colistin or tigecycline administration and tracheostomy, while TigR-Kp bacteraemia as compared to either patients with bacteraemia by tigecycline-susceptible isolate or patients without carbapenemase-producing K. pneumoniae bacteraemia were colistin or tigecycline administration, number of comorbidities and prior bacteraemia by a Gram-negative pathogen. Administration of colistin and tigecycline predisposed to development of bacteraemia by either ColR-Kp or TigR-Kp.
