    Abstract SARS-CoV-2 infection has produced a pandemic with serious consequences for our health care system. Although liver transplant patients represent only a minority of the population, the hepatologists who follow these patients have tried to coordinate efforts to produce a protocol the management of immunosuppression during SARS-CoV-2 infection. Although there are no solid studies to support general recommendations, experiences with other viral infections (hepatitis C, cytomegalovirus) suggest that management of immunosuppression without mycophenolate mofetil or m-Tor inhibitors (drugs that are also associated with leukopenia and lymphopenia) may be beneficial. It is also important to pay attention to possible drug interactions, especially in the case of tacrolimus, with some of the treatments with antiviral effect given in the context of COVID 19 (lopinavir/ritonavir, azithromycin). Finally, the immunosuppressive effect of immunomodulating drugs (tocilizumab and similar) administered to patients with severe lung disease should be taken into account. The mechanisms of action of the different immunosuppressive drugs are reviewed in this article, as well as their potential effect on SARS-CoV-2 infection, and suggests guidelines for the management of immunosuppression.

    Abstract Objective: Assess cost-effectiveness and -utility associated with posttransplant HCC surveillance compared to standard follow-up.
    Summary of background data: Despite lack of prospective clinical data, expert consensus recommends posttransplant surveillance to detect HCC recurrence in a latent phase, while it might be amenable to curative-intent therapy.
    Methods: A Markov-based transition model was created to estimate life expectancy and quality-of-life among liver transplant patients undergoing HCC surveillance. Models were built for 2 cohorts: 1 undergoing HCC surveillance with contrast-enhanced computed tomography of chest and abdomen and serum alpha-fetoprotein analysis and the other receiving standard posttransplant follow-up. Primary model outputs included LY and QALY gains, incremental cost-effectiveness ratio, and incremental cost-utility ratio. Willingness-to-pay for a QALY gain (cost-effectiveness threshold) was used to estimate efficiency.
    Results: Surveillance was marginally more effective versus no surveillance, resulting in means of 0.069 LYs and 0.026 QALYs gained. Costs for surveillance were increased by an average of 988.32€, resulting in incremental cost-effectiveness ratio 14,410.15€/LY and incremental cost-utility ratio 37,547.97€/QALY. Surveillance did not seem cost-effective in our setting, considering willingness-to-pay threshold of 25,000€/QALY. Probabilistic sensitivity analysis indicated surveillance might be cost-effective in 42% of cases, but degree of uncertainty in the analysis was high.
    Conclusions: Performing posttransplant HCC surveillance offers marginal clinical benefits and increases costs. Although expert consensus supports surveillance, results of this decision analysis raise doubt regarding the utility of such recommendations and support ongoing need for prospective clinical trials.

    Abstract Background: The management of liver transplantation has become a complex process involving different healthcare professionals. Teamwork, standardisation and definition of the best practices are essential for success, patient satisfaction and society's favourable perception of transplantation programmes.ISO 9001:2015 certification provides the necessary elements to help implement a quality management system (QMS) to ensure that patient care is performed with the highest guarantees of clinical quality and safety. The aim of this study is to describe the steps, strengths and limitations in the implementation of a QMS in a liver transplant programme (LTP).
    Project management method: This included analysing the starting point, setting up a working group, training, defining the scope of certification, preparing documentation, and conducting an internal and external audit, which culminated in the ISO 9001 quality certification award. The scope of QMS includes all the processes of LTP, from referral of candidates to long-term follow-up after transplantation.
    Results: The project was structured in seven phases that took place between 2008 and 2011. The implementation of QMS led to the generation of all the necessary documentation to meet the requirements of the standard, including internal and legal requirements related to the transplant activity. The establishment of indicators to measure the effectiveness of processes, risk management and the identification of incidents allows us to implement measures devoted to avoiding the deficiencies and to meet the established objectives.
    Conclusion: ISO 9001:2015 certification has contributed to the adaptation of a new quality and safety culture focused on the patient. All activities are protocolised, everything is recorded, measured, and verified, and all steps are taken as planned. Work is carried out in terms of continuous improvement. This has led to less variability in daily clinical practice and a better understanding of work dynamics.

    Abstract Introduction: The use of noninvasive biomarkers may avoid the need for liver biopsy (LB) and could guide immunosuppression adjustment in liver transplantation (LT). The aims of this study were: to confirm the predictive and diagnostic capacity of plasmatic expression of miR-155-5p, miR-181a-5p, miR-122-5p and CXCL-10 for assessing T-cell mediated rejection (TCMR) risk; to develop a score based on a panel of noninvasive biomarkers to predict graft rejection risk and to validate this score in a separate cohort.
    Methods: A prospective, observational study was conducted with a cohort of 79 patients followed during the first year after LT. Plasma samples were collected at predetermined time points for the analysis of miRNAs and the CXCL-10. Patients with LFTs abnormalities were submitted to a LB to rule out rejection, assessing previous and concurrent expression of the biomarkers to evaluate their predictive and diagnostic ability. Information from 86 patients included in a previous study was collected and used as a validation cohort.
    Results: Twenty-four rejection episodes were diagnosed in 22 patients. Plasmatic CXCL-10 concentration and the expression of the three miRNAs were significantly elevated prior to and at the moment of the diagnosis of rejection. We developed a logistic model for rejection prediction and diagnosis, which included CXCL-10, miR-155-5p and miR-181a-5p. The area under the ROC curve (AUROC) for rejection prediction was 0.975 (79.6% sensitivity, 99.1% specificity, 90,7% PPV; 97.7% NPV; 97.1% correctly classified) and 0.99 for diagnosis (87.5% sensitivity, 99.5% specificity, 91.3% PPV; 99.3% NPV; 98.9% correctly classified). In the validation cohort (n=86; 14 rejections), the same cut-off points were used obtaining AUROCs for rejection prediction and diagnosis of 0.89 and 0.92 respectively. In patients with graft dysfunction in both cohorts the score could discriminate those with rejection regarding other causes with an AUROC of 0.98 (97.3% sensitivity, 94.1%specificity).
    Conclusion: These results suggest that the clinical implementation of the monitoring of this noninvasive plasmatic score may allow the prediction and diagnosis of rejection and identify patients with graft dysfunction due to rejection, helping with a more efficient guide for immunosuppressive therapy adjustment. This finding warrants the development of prospective biomarker-guided clinical trials.
