P-62 INFECTIONS IN THE FIRST MONTH POST LIVER TRANSPLANTATION IN A TRANSPLANT CENTER IN CHILE

Introduction Infections are an important cause of morbidity and mortality in the first month after liver transplantation (LT). It is important to know the local microbiology involved and the resistance patterns, to guide treatment appropriately. Objective To characterize infections in the first month after LT in patients from the Hospital Clinico de la Universidad de Chile. Methods Retrospective study of clinical records of 70 consecutive LT between February 2016 and October 2018. Results 20 infectious events in 16 patients (23%). In 75% it was possible to isolate agent. Eight (40%) were bacteria, 5 were fungi and 2 were viruses; 25% were bacteremia, 20% urinary tract, 20% pulmonary, 10% intra-abdominal, and 5% skin. The agents were: K. pneumoniae (2), S. epidermidis (2), E. faecium (1), C. freundii (1), E. coli (1), S. malthophilia (1). Candidas (4), Aspergillus (1), varicella zoster virus (1), respiratory syncytial virus (1). It was not possible to identify a focus in 4 patients. There was antimicrobial resistance in 7 (35%) of the cases, 3 being multi-resistant (2 due to K. pneumoniae and 1 due to S. epidermidis). 4 microorganisms showed antimicrobial resistance (E. coli, C. freundii, E. faecium, and C. glabatra). The infection was the cause of in-hospital mortality in 2 patients. Conclusion Infections in the first month after LT are frequent in our center, the majority of bacterial origin, as reported by international series. More than 1/3 of the patients present an agent with antimicrobial resistance, which should be considered in the choice of empirical therapy.
