RESUMO
BACKGROUND: Carbapenem-resistant Enterobacterales (CRE) colonisation at liver transplantation (LT) increases the risk of CRE infection after LT, which impacts on recipients' survival. Colonization status usually becomes evident only near LT. Thus, predictive models can be useful to guide antibiotic prophylaxis in endemic centres. AIMS: This study aimed to identify risk factors for CRE colonisation at LT in order to build a predictive model. METHODS: Retrospective multicentre study including consecutive adult patients who underwent LT, from 2010 to 2019, at two large teaching hospitals. We excluded patients who had CRE infections within 90 days before LT. CRE screening was performed in all patients on the day of LT. Exposure variables were considered within 90 days before LT and included cirrhosis complications, underlying disease, time on the waiting list, MELD and CLIF-SOFA scores, antibiotic use, intensive care unit and hospital stay, and infections. A machine learning model was trained to detect the probability of a patient being colonized with CRE at LT. RESULTS: A total of 1544 patients were analyzed, 116 (7.5%) patients were colonized by CRE at LT. The median time from CRE isolation to LT was 5 days. Use of antibiotics, hepato-renal syndrome, worst CLIF sofa score, and use of beta-lactam/beta-lactamase inhibitor increased the probability of a patient having pre-LT CRE. The proposed algorithm had a sensitivity of 66% and a specificity of 83% with a negative predictive value of 97%. CONCLUSIONS: We created a model able to predict CRE colonization at LT based on easy-to-obtain features that could guide antibiotic prophylaxis.

Liver transplant candidates and recipients are at high risk of psychological distress. Social, psychological and psychiatric patterns seem to influence morbidity and mortality of patients before and after transplant. An accurate organ allocation is mandatory to guarantee an optimal graft and recipient survival. In this context, the pre-transplant social, psychological and psychiatric selection of potential candidates is essential for excluding major psychiatric illness and for estimating the patient compliance. Depression is one of the most studied psychological conditions in the field of organ transplantation. Notably, an ineffectively treated depression in the pre-transplant period has been associated to a worst long-term recipient survival. After transplant, personalized psychological intervention might favor recovery process, improvement of quality of life and immunosuppressant adherence. Active coping strategy represents one of the most encouraging ways to positively influence the clinical course of transplanted patients. In conclusion, multidisciplinary team should act in three directions: prevention of mood distress, early diagnosis and effective treatment. Active coping, social support and multidisciplinary approach might improve the clinical outcome of transplanted patients.

INTRODUCTION: Hepatitis C virus genotype 4 is predominant in the Middle East and Northern Africa, even if it has recently spread to Southern Europe. Data about the treatment of post-liver transplantation (LT) genotype 4 hepatitis C recurrence are scarce. We report a retrospective analysis of post-LT genotype 4 hepatitis C treatment in 9 Italian transplant centres, focusing on the overall survival rates and treatment outcome. RESULTS: Among 452 recipients, we identified 17 HCV genotype 4 patients (16 males, 1 female) transplanted between 1998 and 2007. All patients received combined antiviral treatment with conventional doses of interferon (recombinant or pegylated) and ribavirin after histological diagnosis of hepatitis C recurrence. The observed overall survival after LT was 100% at 1 year and 83.3% at 5 years. More than 1/3 (35.3%) of patients achieved a sustained virological response (SVR) and 40% (data available in 15 subjects) an early virological response (EVR), which was significantly associated with the achievement of SVR (overall accuracy: 85.7%; predictive values of EVR absence/presence 80/88.8%; chi-square p < 0.05). CONCLUSION: In conclusion, in post-LT genotype 4 hepatitis C treatment, SVR rates are similar to genotype 1. Patients who don't show an EVR are not likely to achieve a SVR.
