Acinetobacter baumannii has become an increasingly important nosocomial pathogen. Carbapenem is the preferred drug of choice for treatment of multidrug-resistant gram-negative bacilli, but carbapenem-resistant A baumannii (CRAB) has now emerged. The aim of this study was to determine the incidence, outcomes, and risk factors for CRAB bacteremia in liver transplant recipients.The medical records of 393 subjects who underwent living donor liver transplant at Seoul St. Mary's Hospital from January 2008 to April 2015 were reviewed.A total of 92 (23.4%) bacteremic patients, comprising 156 episodes, were identified. Fourteen patients, totaling 18 episodes, had CRAB bacteremia. The median time of emergence of CRAB bacteremia was 55.5 (range, 2-829) days after transplantation, and 72.2% of episodes (n = 13) occurred within 6 months of transplant. The presumed sources of infection were intra-abdominal (n = 11, 61.1%), biliary tract (n = 3, 16.7%), lung (n = 2, 11.1%), catheter (n = 1, 5.6%), and wound (n = 1, 5.6%). By multivariate analysis, length of post-transplant intensive care unit (ICU) stay (odds ratio [OR], 1.1, 95% confidence interval [CI], 1.11-1.15; P = .04) was associated with CRAB bacteremia. Overall mortality in 14 recipients with CRAB bacteremia was 50% (n = 7), but only 10% (30 of 301) in non-bacteremic patients and 20.5% (16 of 78) in other bacteremic patients excluding CRAB (P < .001).In our study, patients with CRAB bacteremia after liver transplant showed an unfavorable outcome and, recently, CRAB has become an increasingly major pathogen at our center. Reducing the length of ICU stay could be a solution for preventing CRAB bacteremia.
