Background Despite the use of antimicrobial prophylaxis in liver transplant recipients (LTR), infection remains the most likely cause of death (18.94%) in the first year. There is limited data describing the characteristics, & infections of LTR while hospitalized in the first year post-transplantation. We aimed to review the incidence and outcomes of infections in LTR in the first year post-transplant during hospitalization or re-hospitalization. Graph 1.Y-axis; Number of cultures collected, X-axis; type of organism dived over time. Site of bacterial infection Table 1.Number of bacterial infections divided by site/system, involved compared to timing of infection. Methods We performed a single-center retrospective cohort study at The University of Rochester. Electronic medical records of 298 first time adult LTR between 03/5/2011 and 04/01/2020 were reviewed. Demographic and comorbidity data was obtained at time of transplant. Microbiologic data and outcomes were obtained during the first year post-transplant. We compared mortality between those with infection and those without using log-rank survival analysis. Graph 2. Y-Axis; Number of patients with diagnosed viral infection. X-axis virus divided over time. Results 160 (53.7%) patients suffered at least 1 infection while hospitalized in the first year post-transplant. There were 178 bacterial infections in 130 patients of which 115 were intra-abdominal (table 1). The most common organism was Enterococcus sp. (n=102), 65 were vancomycin resistant (VRE). The most common site of fungal infection was abdominal (n=13) and the most common organism was C. glabrata (n=9). The most common viral infection was CMV at 7-12 months although other viral infections occurred between 1-6 months (graph 2). In a univariate chi-square model, bacterial infection at any time was associated with all-cause mortality in the first year (CI 1.7-8.9 p-adj= 0.002). Fungal infection between 2-6 months was also associated with increased mortality (CI 2.7-12.2 p-adj= 0.0005). Conclusion Bacterial infections are the most common type of infection in LTR and occur more frequently during the first 6 months. Bacterial infection at any point was independently associated with increased mortality in the first year post-transplant. The most common organism was Enterococcus with a high rate of VRE which should be taken into consideration for empiric coverage at our institution. Fungal infection between 2 to 6 months was associated with increased mortality. We observed that early bacterial and fungal infections are markers of poor prognosis.
