Carbapenemase-producing Enterobacteriacea (CPE) cause serious and life-threatening infections. They are resistant to carbapenems and many other classes of commonly used antimicrobial agents; therefore, managing infections caused by them poses a substantial challenge in clinical practice. They can also cause morbidity and mortality in patients with liver transplant. A retrospective analysis of CPE culture-positive patients with a history of liver transplant can help to examine the epidemiology and microbiology of these bacteria, as well as gain information on the possible infection sources, susceptibility patterns, and expected mortality in infected populations. In addition, study of these bacteria could help formulate a consensus on the appropriate use of empirical and directed antibiotic therapy, which can effectively reduce infections in these patients. We reviewed the medical records of 142 subjects who underwent liver transplantation at Ankara University Hospital, a 1900-bed tertiary care university hospital, in Ankara, Turkey, between January 2014 and August 2018. Patients showing signs of infection with culture positivity for CPE-producing organisms were included from the study. Statistical analysis was performed and a value of P < .05 is considered statistically significant. In most cases, the source of infection was the abdomen. Klebsiella species was also predominant in these cases. Model for End-Stage Liver Disease scores and length of hospital stay were higher and statistically significant when compared to patients who were CPE negative. Mortality was highest in the CPE-positive group. Infection is the most important cause of mortality and morbidity after liver transplantation and increases the cost of treatment. Regarding the culture sensitivity patterns and resistance mode, empirical therapy with carbapenems does not produce a solid result. The high mortality observed with these infections reflects very limited therapeutic options.
