Abstract
Liver transplantation offers a new lease of life to patients with end-stage liver disease and hepatocellular carcinoma. However, the implantation of an exogenous allograft and the accompanying immunosuppression bring their own challenges. Moreover, the persistence of risk factors for the initial liver insult place the new graft at a higher risk of damage. With the increasing number of liver transplants along with the improvement in survival posttransplant, the recurrence of primary disease in liver grafts has become more common. Pre-2015, the most common disease to recur after transplant was hepatitis C. However, directly acting antivirals have nearly eliminated this problem. The greatest challenge of disease recurrence we now face are those of nonalcoholic steatohepatitis, alcohol-related liver disease, and primary sclerosing cholangitis. We focus on the epidemiology and pathophysiology of the recurrence of primary disease after transplant. We also discuss means of early identification, risk stratification, prevention, and management of recurrent primary disease after liver transplantation.

Metabolic-Dysfunction-Associated Steatotic Liver Disease (MASLD) after Liver Transplantation: A Narrative Review of an Emerging Issue. J Clin Med 2024; 13:3871.

Abstract
The development of steatotic liver disease after liver transplant (LT) is widely described, and epidemiological data have revealed an increased incidence in recent times. Its evolution runs from simple steatosis to steatohepatitis and, in a small proportion of patients, to significant fibrosis and cirrhosis. Apparently, post-LT steatotic disease has no impact on the recipient's overall survival; however, a higher cardiovascular and malignancy burden has been reported. Many donors' and recipients' risk factors have been associated with this occurrence, although the recipient-related ones seem of greater impact. Particularly, pre- and post-LT metabolic alterations are strictly associated with steatotic graft disease, sharing common pathophysiologic mechanisms that converge on insulin resistance. Other relevant risk factors include genetic variants, sex, age, baseline liver diseases, and immunosuppressive drugs. Diagnostic evaluation relies on liver biopsy, although non-invasive methods are being increasingly used to detect and monitor both steatosis and fibrosis stages. Management requires a multifaceted approach focusing on lifestyle modifications, the optimization of immunosuppressive therapy, and the management of metabolic complications. This review aims to synthesize the current knowledge of post-LT steatotic liver disease, focusing on the recent definition of metabolic-dysfunction-associated steatotic liver disease (MASLD) and its metabolic and multisystemic concerns.

Abstract
Improvement in immunosuppression has led to a remarkable improvement in short-term and long-term outcomes post-liver transplant (LT). However, with improvements in long-term survival, complications related to immunosuppressive drugs, either directly or indirectly, have also increased. The adverse events could be drug-specific, class-specific, or generic. Calcineurin inhibitors (cyclosporine and tacrolimus) are the backbone of the immunosuppression after LT and the main culprit associated with most of the complications, including renal failure, post-transplant diabetes mellitus (PTDM), and metabolic syndrome. Steroids are also implicated in the development of diabetes, osteoporosis, and metabolic syndrome post-LT. The development of infections and de novo malignancies (DNMs) is a generic effect linked to the overall cumulative immunosuppression. The development of these complications significantly hampers the quality of life and leads to increased morbidity and mortality post-LT. Thus, it is important to minimize the cumulative immunosuppression dose while simultaneously preventing allograft rejection. This review provides up-to-date, comprehensive knowledge of the complications of long-term immunosuppression post-LT along with associated risk factors and strategies to minimize the risk of complications.

Abstract
Despite advances in posttransplant care, long-term outcomes for liver transplant recipients remain unchanged. Approximately 25% of recipients will advance to graft cirrhosis and require retransplantation. Graft fibrosis progresses in the context of de novo or recurrent disease. Recurrent hepatitis C virus infection was previously the most important cause of graft failure but is now curable in the majority of patients. However, with an increasing prevalence of obesity and diabetes and nonalcoholic fatty liver disease as the most rapidly increasing indication for liver transplantation, metabolic dysfunction-associated liver injury is anticipated to become an important cause of graft fibrosis alongside alloimmune hepatitis and alcoholic liver disease. To better understand the landscape of the graft fibrosis literature, we summarize the associated epidemiology, cause, potential mechanisms, diagnosis, and complications. We additionally highlight the need for better noninvasive methods to ameliorate the management of graft fibrosis. Some examples include leveraging the microbiome, genetic, and machine learning methods to address these limitations. Overall, graft fibrosis is routinely seen by transplant clinicians, but it requires a better understanding of its underlying biology and contributors that can help inform diagnostic and therapeutic practices.

Abstract
Non-alcoholic fatty liver disease (NAFLD) has emerged as one of the common causes of cirrhosis and hepatocellular carcinoma (HCC) and is a leading indication for liver transplantation (LT). Patients with NAFLD-related cirrhosis and HCC are at high risk for the development of recurrent NAFLD after LT. NAFLD can also develop de novo post-transplantation in patients subjected to LT for other indications. Besides the pretransplant presence of various components of metabolic syndrome (MS) use of immunosuppressive agents in the post-LT setting forms one of the major drivers for the development of post-LT NAFLD. Individual components of conventional immunosuppressive regimens (corticosteroids, calcineurin inhibitors, and m-TOR inhibitors) are all implicated in the development of post-LT metabolic derangement and follow unique mechanisms of action and degree of disturbances. The development of cardiovascular risk is associated with post-LT NAFLD, although graft outcomes do not seem to be influenced only by the presence of post-LT NAFLD. Measures in consonance with the management of NAFLD, in general, including lifestyle modifications and control of metabolic risk factors, hold true for post-LT NAFLD. Tailoring immunosuppression strategies with early corticosteroid withdrawal and calcineurin inhibitor minimization balancing against the risk of graft rejection constitutes important nuances in the individualized management of post-LT NAFLD.

Abstract
Transient elastography by FibroScan® (Echosens, Paris, France) is a non-invasive method that can provide a reliable measurement of liver fibrosis through the evaluation of liver stiffness. Despite its limitations and risks, liver biopsy has thus far been the only procedure able to provide data to quantify fibrosis. Scientific evidence and clinical practice have made it possible to use FibroScan® in the diagnostic work-up of several liver diseases to monitor patients' long-term treatment response and for complication prevention. For these reasons, this procedure is widely used in clinical practice and is still being investigated for further applications. The aim of this narrative review is to provide a comprehensive overview of the main applications of transient elastography in the current clinical practice.

Abstract
NAFLD can occur after liver transplantation (LT), as recurrence or de novo hepatic steatosis (HS). We aimed to evaluate the literature on prevalence, risk factors, and prognosis of post-LT HS. Systematic review with meta-analysis through a search on: PUBMED, Scopus, and Web-of-Science, from inception until the September 30, 2021. Forty studies were included, representing 6979 patients. The post-LT HS prevalence was 39.76% (95% CI, 34.06-45.46), with a rising kinetics (11.06% increase per decade, p =0.04), and a geographical distribution (15.10% more prevalent in American continent compared with Europe and Asia). Recurrent HS was up to 5-fold more likely than de novo HS [OR: 5.38 (2.69-10.76)]. Metabolic disturbances were stronger risk factors in the post-LT recipient [obesity: OR: 4.62 (3.07-6.96); metabolic syndrome: OR: 3.26 (2.03-5.25)] as compared with pre-LT recipients, with the exception of diabetes mellitus, which doubled the risk at any set [pre-LT diabetes mellitus: OR: 2.06 (1.58-2.68); post-LT diabetes mellitus: OR: 2.12 (1.73-2.59)]. Donor factors were not the relevant risk factors for post-LT HS and the only immunosuppressive drug associated with increased risk was sirolimus [OR: 1.68 (1.07-2.64)]. The prevalence of post-LT steatohepatitis was 28.82% (19.62-38.03) and the strongest risk factor was pre-LT NAFLD. Limited outcomes data suggest that post-LT HS did not increase the risk for liver cirrhosis or mortality in these studies. Two out of 5 patients submitted to LT will develop post-LT HS, being recurrent HS more common than de novo HS. Diabetes mellitus and post-LT metabolic syndrome are the strongest risk factors for HS and baseline NAFLD for steatohepatitis. All transplanted patients should be enrolled in lifestyle interventions to prevent post-LT metabolic syndrome, and sirolimus should be avoided in high-risk patients.

Abstract
Background & Aims Liver transplantation (LT) is the only available treatment for end-stage non-alcoholic fatty liver disease (NAFLD) (related decompensated cirrhosis and/or hepatocellular carcinoma). The aim of our study was to evaluate the risk of disease recurrence after LT and the factors influencing it. Method This retrospective multicenter study included adults transplanted for NAFLD cirrhosis between 2000 and 2019 in 20 participating French-speaking centers. Disease recurrence (steatosis, steatohepatitis and fibrosis) was diagnosed from liver graft biopsies. Results We analyzed 150 patients with at least one graft liver biopsy available ≥6 months after transplantation, among 361 patients transplanted for NAFLD. The median (IQR) age at LT was 61.3 (54.4-64.6) years. The median follow-up after LT was 4.7 (2.8-8.1) years. The cumulative recurrence rates of steatosis and steatohepatitis at 5 years were 80.0% and 60.3%, respectively. Significant risk factors for steatohepatitis recurrence in multivariate analysis were recipient age at LT <65 years (odds ratio [OR] 4.214; p = 0.044), high-density lipoprotein-cholesterol <1.15 mmol/L after LT (OR 3.463; p = 0.013) and grade ≥2 steatosis on the graft at 1 year after LT (OR 10.196; p = 0.001). The cumulative incidence of advanced fibrosis (F3-F4) was 20.0% at 5 years after LT and significant risk factors from multivariate analysis were metabolic syndrome before LT (OR 8.550; p = 0.038), long-term use of cyclosporine (OR 11.388; p = 0.031) and grade ≥2 steatosis at 1 year after LT (OR 10.720; p = 0.049). No re-LT was performed for NAFLD cirrhosis recurrence. Conclusion Our results strongly suggest that recurrence of initial disease after LT for NAFLD is inevitable and progressive in a large proportion of patients; the means to prevent it remain to be further evaluated. Impact and implications Non-alcoholic fatty liver disease (NAFLD) is a growing indication for liver transplantation, but the analysis of disease recurrence, based on graft liver biopsies, has been poorly studied. Cumulative incidences of steatosis, steatohepatitis and NAFLD-related significant fibrosis recurrence at 5 years were 85.0%, 60.3% and 48.0%, respectively. Grade ≥2 steatosis on graft biopsy at 1 year (present in 25% of patients) is highly predictive of recurrence of steatohepatitis and advanced fibrosis: bariatric surgery should be discussed in these patients specifically.

Abstract
Aim The course of cryptogenic cirrhosis (CC) after liver transplantation (LT) is unknown. We therefore clarified the natural course post-LT for CC and investigated the etiology of CC. Methods Eighteen patients who underwent LT for CC were included. To rule out the possibility of NASH in patients with CC, those with a history of obesity or liver steatosis found pretransplantation were excluded. A liver biopsy was performed one year after LT and annually thereafter. Results Liver steatosis and steatohepatitis were identified in 61% and 39% of patients after LT, respectively, with a median time to the onset of 12 and 27 months, respectively. There were no other pathological findings such as liver allograft rejection, autoimmune hepatitis, or primary biliary cholangitis. The body mass index after LT (28.5 vs. 22.4 kg/m2; P=0.002) and mean muscle attenuation at the time of LT were significantly higher (33.3 vs. 25.8 Hounsfield units, P=0.03) and the postoperative hospitalization period shorter (50 vs. 102 days; P=0.02) in the steatosis group than in the non-steatosis group. Recipients were significantly younger in the steatohepatitis subgroup than in the simple steatosis subgroup (55.0 vs. 63.5 years old; P=0.04). Conclusions Despite excluding CC patients with a history of obesity, we observed that patients with CC had a high prevalence of steatosis after LT than those without CC. Young patients with a favorable postoperative course were noted to have a high risk of NASH after LT for CC. Patients with CC may represent cases of non-obese NASH.

Predictors of patient survival following liver transplant in non-alcoholic steatohepatitis: A systematic review and meta-analysis. EClinicalMedicine 2022; 50:101534. [PMID: 35812989 PMCID: PMC9257342 DOI: 10.1016/j.eclinm.2022.101534] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2021] [Revised: 06/01/2022] [Accepted: 06/08/2022] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Non-alcoholic steatohepatitis (NASH) is the second-leading indication for liver transplantation (LT) worldwide and is projected to become the leading indication. Our study aimed to determine clinical variables that predict post-LT survival in NASH. METHODS A systematic review and meta-analysis was performed. On June 18, 2020 and April 28, 2022, Ovid MEDLINE ALL, Ovid Embase, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials were searched. No date limits were applied. Inclusion criteria specified the type of study and our study's population/comparison and outcome/timepoints. Pediatric, animal, retransplantation-only, and studies classifying cryptogenic cirrhosis patients with body mass index (BMI) <30 as NASH were excluded. Studies with duplicate cohorts and missing information were excluded from the meta-analysis. Studies were appraised using the Newcastle-Ottawa Scale. This study was preregistered in PROSPERO (CRD42020196915). FINDINGS Out of 8583 studies identified, 25 studies were included in the systematic review, while 5 studies were included in the meta-analysis. Our quantitative review suggested that the following variables were predictive of post-LT NASH patient survival: recipient age, functional status, pre-LT hepatoma, model for end-stage liver disease (MELD) score, diabetes mellitus (DM), pre-LT dialysis, hepatic encephalopathy, portal vein thrombosis, hospitalization/ICU at LT, and year of LT. Predictors of graft survival included recipient age, BMI, pre-LT dialysis, and DM. Our pooled meta-analyses included five predictors of patient survival. Increased patient mortality was associated with older recipient age (HR=2·07, 95%CI: 1·71-2·50, I2=0, τ2=0, p=0·40) and pretransplant DM (HR=1·18, 95%CI: 1·08-1·28, I2=0, τ2=0, p=0·76). INTERPRETATION Our systematic review and meta-analysis aimed to synthesise predictive variables of mortality in LT NASH patients. Clinically, this might help to identify modifiable risk factors that can be optimized in the post-transplant setting to improve patient outcomes and optimises decision making in the resource-limited LT setting.

A Comprehensive Review on the Risk of Metabolic Syndrome and Cardiovascular Disease after Liver Transplantation. LIVERS 2022.

Abstract
Survival rates after liver transplantation have increased dramatically over the past 20 years. Cardiovascular disease is the most common extra-hepatic cause of mortality in the long-term post liver transplant. This is intimately linked with both the higher pre-existing rates of metabolic syndrome in these patients as well as increased propensity to develop de novo metabolic syndrome post-transplant. This unfavorable metabolic profile that contributes to cardiovascular disease is multifactorial and largely preventable. This review explores metabolic syndrome and cardiovascular disease and their contributory factors post liver transplantation to highlight areas for potential intervention and thus reduce the significant morbidity and mortality of patients due to metabolic syndrome and cardiovascular disease.

Abstract
Metabolic dysfunction-associated fatty liver disease (MAFLD) is a new acronym adopted from the consensus of international experts. Given the increasing prevalence of MAFLD in pre-transplant settings, de novo and recurrent graft steatosis/MAFLD are common in post-transplant settings. The impact of graft steatosis on long-term outcomes is unclear. The current knowledge of incidence rate, risk factors, diagnosis, long-term outcomes, and management of graft steatosis (both de novo and recurrent) is discussed in this review.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a rising indication for liver transplantation (LT). Identification of NAFLD recurrence and those at risk for more progressive disease after LT remains elusive as the diagnosis requires biopsy, which is invasive and impractical for serial monitoring. We therefore aimed to identify metabolites in the blood associated with recurrent NAFLD that could potentially be used for detection and monitoring.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease in the world. The rising prevalence of nonalcoholic steatohepatitis (NASH) has led to a 170% increase in NASH cirrhosis as the listing indication for liver transplantation from 2004 to 2013. As of 2018, NASH has overtaken hepatitis C as an indication for liver transplantation in the USA. After liver transplantation, the allograft often develops recurrent NAFLD among patients with known NASH cirrhosis. In addition to recurrent disease, de novo NAFLD has been reported in patients with other indications for liver transplantation. In this review, we will discuss the risk factors associated with recurrent and de novo NAFLD, natural course of the disease, and management strategies after liver transplantation.

Abstract
Due to the rising prevalence of obesity and type II diabetes mellitus, non-alcoholic fatty liver disease is becoming the leading cause of chronic liver disease in the Western world. In some patients, simple steatosis can result in non-alcoholic steatohepatitis which over time can lead to liver cirrhosis and its associated sequelae, including hepatocellular carcinoma. Early identification and management of patients at risk with intensive dietary and lifestyle modification are essential to prevent the development of advanced liver disease and its complications. In this review, we will discuss the epidemiology of non-alcoholic fatty liver disease, pathogenesis, diagnosis, management and surveillance strategies to offset the morbidity and mortality of this disease, as well as liver and non-liver-related complications.

Abstract
Obesity is increasing in prevalence in liver transplant candidates and recipients. The rise in liver transplantation for nonalcoholic steatohepatitis reflects this increase. Management of obesity in liver transplant candidates can be challenging due to the presence of decompensated cirrhosis and sarcopenia. Obesity may increase peritransplant morbidity but does not have an impact on long-term post-transplant survival. Bariatric surgery may be a feasible option in select patients before, during, or after liver transplantation. Use of weight loss drugs and/or endoscopic therapies for obesity management ultimately may play a role in liver transplant patients, but more research is needed to determine safety.

Abstract
INTRODUCTION Hepatocellular carcinoma (HCC) is an increasingly common disease with liver transplant (LT) the best long-term therapy for early stage disease. We will review the data for assessing risk and managing recurrence for patients undergoing LT for HCC. AREAS COVERED In this review, we will provide an overview of methods of patient risk stratification in the post-transplant period, the data around surveillance for HCC recurrence, and the evidence for and against post-LT adjuvant treatment strategies. Finally, we will provide data regarding treatment options for patients with HCC recurrence after LT. Using an extensive search of original papers and society guidelines, this paper provides a comprehensive review of the data for assessing risk and managing recurrence for patients undergoing LT for HCC. EXPERT OPINION The development of multiple post-transplant prognostic scoring systems have allowed for improved assessment of recurrence risk and stratification of patients. However, the ability to translate this information into surveillance and therapeutic strategies that improve patient outcomes still have to be fully demonstrated. Post-LT immunosuppression strategies have been implemented in order to attempt to reduce this risk. Evidence-based strategies for managing recurrent HCC are evolving. We expect that with further understanding of individual patient characteristics will allow for optimal therapeutic selection.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is one of the most common causes of liver disease and non-alcoholic steatohepatitis (NASH) related cirrhosis is third common indication for liver transplantation (LT). Patients who have NASH related cirrhosis and are candidates for LT often have multiple comorbidities. These comorbidities need to be addressed before and after transplantation as it affects overall survival. Like hepatitis B, hepatitis C, primary biliary cirrhosis, autoimmune hepatitis which recurs after transplantation, NASH also recurs after transplant however the impact of the recurrence on allograft and patient outcomes is unclear. Limited data suggests that it does not affect graft and patient survival. De novo NAFLD which is defined as occurrence of fatty liver in a patient who did not have fatty liver prior to LT can also occur in the allograft of patients transplanted for non-NAFLD liver disease. Obesity, hyperlipidemia, diabetes as well as steroid dose and duration after LT are common predictors of recurrence of NAFLD after transplantation. Studies on prevention and treatment of NASH in post-transplant patients are lacking. Prevention of weight gain, regular exercises, weight reducing surgery, limited steroid use or steroid free regimen have been tried with varying success. Future studies for the prevention of NAFLD/NASH are required especially in post liver transplant patient.

Abstract
INTRODUCTION Liver transplantation is a life-changing event for patients and survival following transplantation has improved significantly since the first transplantation in 1967. Following liver transplantation, patients face a unique set of healthcare management decisions including transplantation-specific complications, recurrence of primary liver disease, as well as metabolic and malignancy concerns related to immunosuppression. As more patients with liver disease receive transplantation and live longer, understanding and managing these patients will require not only transplant specialist but also local subspecialist and primary care physicians. AREAS COVERED This review covers common issues related to the management of patients following liver transplantation including immunosuppression, liver allograft dysfunction, metabolic complications, as well as routine health maintenance such as immunizations and cancer screening. EXPERT OPINION Optimizing medical care for patients following liver transplant will benefit from ensuring all providers, not just transplant specialist, have a basic understanding of the common issues encountered in the post-transplant patient. This review provides an overview of common healthcare concerns and management options for patients following liver transplantation.

Incidence and Risks for Nonalcoholic Fatty Liver Disease and Steatohepatitis Post-liver Transplant: Systematic Review and Meta-analysis. Transplantation 2020; 103:e345-e354.

Abstract
BACKGROUND The true incidence and unique risk factors for recurrent and de novo nonalcoholic fatty liver (NAFLD) and nonalcoholic steatohepatitis (NASH) post-liver transplant (LT) remain poorly characterized. We aimed to identify the incidence and risk factors for recurrent and de novo NAFLD/NASH post-LT. METHODS MEDLINE via PubMed, Embase, Scopus, and CINAHL were searched for studies from 2000 to 2018. Risk of bias was adjudicated using the Newcastle-Ottawa Scale. RESULTS Seventeen studies representing 2378 patients were included. All were retrospective analyses of patients with post-LT liver biopsies, with the exception of 2 studies that used imaging for outcome assessment. Seven studies evaluated occurrence of recurrent NAFLD/NASH, 3 evaluated de novo occurrence, and 7 evaluated both recurrent and de novo. In studies at generally high or moderate risk of bias, mean 1-, 3-, and ≥5-year incidence rates may be 59%, 57%, and 82% for recurrent NAFLD; 67%, 40%, and 78% for de novo NAFLD; 53%, 57.4%, and 38% for recurrent NASH; and 13%, 16%, and 17% for de novo NASH. Multivariate analysis demonstrated that post-LT body mass index (summarized odds ratio = 1.27) and hyperlipidemia were the most consistent predictors of outcomes. CONCLUSIONS There is low confidence in the incidence of recurrent and de novo NAFLD and NASH after LT due to study heterogeneity. Recurrent and de novo NAFLD may occur in over half of recipients as soon as 1 year after LT. NASH recurs in most patients after LT, whereas de novo NASH occurs rarely. NAFLD/NASH after LT is associated with metabolic risk factors.

Abstract
AIM Allograft steatosis is an emerging concern after liver transplantation (LT). The use of transient elastography (TE) with controlled attenuation parameter (CAP) may facilitate early detection of and intervention for allograft steatosis. This study aimed to evaluate the prevalence and risk factors of allograft steatosis using TE and CAP. METHODS The presence of steatosis and severe steatosis were defined by CAP ≥222 and ≥290 dB/m, respectively. Demographics and clinical characteristics were compared between patients with and without severe steatosis. Regression analyses were performed to determine factors associated with severe steatosis. RESULTS Of 150 patients, 105 (70%) had steatosis while 40% of these had severe steatosis. Thirty-four (81.0%) patients with severe steatosis had normal alanine transaminase at the time of TE. In multivariable analyses, age at LT (odds ratio [OR] 1.05, 95% confidence interval [CI] 1.01-1.08), post-LT obesity (OR 5.34, 95% CI 1.53-18.65), and alcoholic liver disease (OR 12.86, 95% CI 2.24-73.74) were significant predictors of severe steatosis. Five patients underwent liver biopsies as a result of advance fibrosis seen on TE and were later diagnosed with chronic allograft rejection. Two of these patients had normal liver chemistries, and the remaining 3 had mild elevation of alkaline phosphatase. CONCLUSION Steatosis was present in 70% of patients who underwent TE after LT. Advanced age at LT, post-LT obesity, and alcoholic liver disease were significant predictors for severe steatosis. The majority of patients with severe steatosis had normal liver enzymes. TE should be considered as a screening modality for allograft steatosis and fibrosis even when liver chemistries are normal.

Abstract
Liver transplantation represents the only curative option for patients with end-stage liver disease, fulminant hepatitis and advanced hepatocellular carcinoma. Even though major advances in transplantation in the last decades have achieved excellent survival rates in the early post-transplantation period, long-term survival is hampered by the lack of improvement in survival in the late post transplantation period (over 5 years after transplantation). The main etiologies for late mortality are malignancies and cardiovascular complications. The latter are increasingly prevalent in liver transplant recipients due to the development or worsening of metabolic syndrome and all its components (arterial hypertension, dyslipidemia, obesity, renal injury, etc.). These comorbidities result from a combination of pre-liver transplant features, immunosuppressive agent side-effects, changes in metabolism and hemodynamics after liver transplantation and the adoption of a sedentary lifestyle. In this review we describe the most prevalent metabolic and cardiovascular complications present after liver transplantation, as well as proposing management strategies.

Abstract
Nonalcoholic steatohepatitis (NASH) is the fastest growing indication for liver transplant (LT)worldwide and is deemed to be the foremost indication in the near future. Recurrence of NASH can occur post LT and has been observed to be a common phenomenon. Baseline metabolic co-morbidities and worsening of metabolic profile post LT are the principal drivers of NASH recurrence. Liver biopsy remains the gold standard for establishing the diagnosis. However, noninvasive methods including transient elastography (TE) and magnetic resonance imaging (MRI) seem to be promising. The implications of recurrent NASH on post LT outcomes, graft steatosis, progression to fibrosis, overall survival, and cardiovascular associations warrant careful evaluation. Control of metabolic parameters and weight gain along with tailored immunosuppression remain the cornerstone of management. Extrapolation of the ever-increasing armamentarium of NASH pharmacotherapy specifically in this population of recurrent NAFLD remains a challenge for the future.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a systemic disorder with a complex multifactorial pathogenesis and heterogenous clinical manifestations. NAFLD, once believed to be an innocuous condition, has now become the most common cause of chronic liver disease in many countries worldwide. NAFLD is already highly prevalent in the general population, and owing to a rising incidence of obesity and diabetes mellitus, the incidence of NAFLD and its impact on global healthcare are expected to increase in the future. A subset of patients with NAFLD develops progressive liver disease leading to cirrhosis, hepatocellular carcinoma, and liver failure. NAFLD has emerged as one of the leading causes of cirrhosis and hepatocellular carcinoma in recent years. Moreover, HCC can occur in NAFLD even in absence of cirrhosis. Compared with the general population, NAFLD increases the risk of liver-related, cardiovascular and all-cause mortality. NAFLD is bidirectionally associated with metabolic syndrome. NAFLD increases the risk and contributes to aggravation of the pathophysiology of atherosclerosis, cardiovascular diseases, diabetes mellitus, and chronic kidney disease. In addition, NAFLD is linked to colorectal polyps, polycystic ovarian syndrome, osteoporosis, obstructive sleep apnea, stroke, and various extrahepatic malignancies. Extended resection of steatotic liver is associated with increased risk of liver failure and mortality. There is an increasing trend of NAFLD-related cirrhosis requiring liver transplantation, and the recurrence of NAFLD in such patients is almost universal. This review discusses the growing burden of NAFLD, its outcomes, and adverse associations with various diseases.

Abstract
Liver biopsy is considered the gold standard method for diagnosing and staging liver disease, particularly in the post-liver transplant setting. Given the invasive nature of biopsy, alternate means for accurately assessing liver fibrosis and steatosis are preferred especially as the number of patients with fatty liver disease is increasing. Transient elastography has been validated as a useful tool for evaluation of liver fibrosis, as has controlled attenuation parameter index as a tool for assessing steatosis. It is a non-invasive, rapid, and highly reproducible approach to demonstrate the presence of fibrosis among non-transplant patients with chronic liver disease of various etiologies. However, it has not yet found wide acceptance in liver transplant recipients. There are few published studies evaluating the merits and applicability of transient elastography to assess allografts after liver transplantation. We review the published data on the use of transient elastography with concurrent controlled attenuation parameter in liver transplant recipients and recommend its greater use to follow allograft function over time.

Abstract
Although hepatocellular carcinoma (HCC) is as prevalent as ever as a cancer-related mortality, and some would even argue that it is increasing, the pattern of its etiologies has been changing. Specifically, the domination of viral hepatitis C virus is being overcome, partly because of the emergence of the antiviral treatments, and partly because of the significant increase, especially in developed countries, of the combination of obesity, diabetes, metabolic syndrome, non-alcoholic fatty liver disease and non-alcoholic steatohepatitis. This editorial will explore the interconnection of this group of diseases and how they are linked to HCC. More importantly, it will argue that this shift in HCC etiology essentially means that we have to change how we approach the treatment of HCC, by changing our focus (and resources) to earlier stages of the disease development in order to prevent the appearance and progression of HCC.

Abstract
BACKGROUND Cirrhosis secondary to nonalcoholic steatohepatitis (NASH) is projected to become the leading indication for liver transplantation (LT) in the USA in the next decade. The long-term implications of post-LT NASH, specifically on the development of allograft cirrhosis, are not well known. METHODS A retrospective cohort of patients at a single large center undergoing LT for NASH from 2000 to 2015 was identified using a prospectively collected database. A total of 226 patients undergoing LT for NASH were identified. Mean follow-up for the cohort was 7 years. Seventy-five percent of patients underwent at least one liver biopsy post-LT. RESULTS Eighty-one patients (36%) developed recurrence of biopsy-proven NASH. Fifteen patients developed bridging fibrosis but only four patients (1.8%) progressed to recurrent NASH cirrhosis at a mean of 9 years post-LT. Body mass index at the time of LT was statistically higher in the NASH allograft cirrhosis group. Recurrent disease was less common and less severe in those transplanted with black donors. All four patients with recurrent NASH cirrhosis developed evidence of portal hypertension, but all remained alive at follow-up. CONCLUSION Although recurrent NASH following LT is common, the development of allograft cirrhosis is rare. These findings are useful when counseling patients and important to consider during their post-LT care.

Abstract
In the last years, nonalcoholic steatohepatitis (NASH) has become a leading indication for liver transplant (LT). After transplant, both recurrent and de novo nonalcoholic fatty liver disease (NAFLD) can be commonly diagnosed. However, dedicated surveillance programs for patients with pre- or post-transplant NAFLD are not available. Areas covered: Patients waiting for LT for NASH show specific peculiarities and would deserve targeted stratification of mortality risk. Obesity, hyperlipidemia, and diabetes mellitus can be often found after transplant. These conditions, together with immunosuppressive regimen, make LT recipients a high-risk population for both recurrent and de novo NAFLD. Development of fatty liver disease after LT has a relevant impact on both morbidity and mortality. Expert commentary: A targeted stratification of neoplastic and cardiovascular risk for patients with NASH waiting for LT would be mandatory. In both pre- and post-transplant period, NAFLD should be considered not only a liver disease but also a cardiovascular risk factor. Patients within Transplant Program, especially those with known metabolic risk factors, should be followed with personalized diagnostic and life-style interventions before and after LT.

Abstract
OBJECTIVES Nonalcoholic steatohepatitis (NASH), which is a common and increasing indication for liver transplantation (LT), is known to recur after LT. Since the recurrence of NASH can lead to graft failure, the identification of predictive factors is needed and preventive strategies should be implemented. METHODS We retrospectively examined 95 patients who had undergone LT for NASH or alcoholic liver disease (ALD) as a primary indication. We evaluated peritransplant characteristics and histological findings 1-year post LT among liver transplant patients due to NASH or ALD. RESULTS Pre-LT body mass index (BMI) was higher and pre-LT diabetes was more prevalent in NASH patients than in ALD patients (p < .01). The difference of BMI persisted at 3 months and 1 year after LT. There were no differences between the groups regarding histopathological findings including the degree of steatosis and fibrosis in 1-year biopsy. In multivariate analysis, recipient age and 1-year BMI were independent risk factors for post-LT fatty liver disease development. Regarding predictive factors of NASH recurrence, the prevalence of pre-LT insulin-dependent diabetes was significantly higher in patients who developed NASH recurrence than those who did not. The increase of HbA1c at 1-year post-LT checkup was higher in patients who developed recurrence than those who did not, although the difference did not reach statistical significance. CONCLUSIONS The results of this study suggest that insulin-dependent diabetes has detrimental effects on NASH recurrence following LT. Optimal glycemic control should be recommended, but studies are needed to prove its preventive effect on NASH recurrence.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is an emerging entity, becoming the most prevalent pediatric chronic liver disease. Its broad spectrum of histological findings, comorbidities, and complications, including cirrhosis and liver failure, can occur in childhood, emphasizing the severity of pediatric NAFLD. Current lifestyle and diet modifications have been linked to the increasing prevalence of NAFLD, including the rise of fructose consumption, a monosaccharide present in foods that contain added sugar, such as sugar‐sweetened beverages. Excessive fructose consumption is believed to cause addiction like alcohol and other drugs. As such, the new term “fructoholism” refers to the consumption of a substance (fructose) that can cause psychological and physical damage and become a major public health concern, highlighting the seriousness of the excessive consumption of fructose in the pediatric age. Hepatic fructose metabolization leads to hepatic steatosis and progression to fibrosis through mechanisms comparable to alcoholic liver disease, hence the term “fructoholic liver disease.” Conclusion: The importance of implementing reliable global strategies, such as education campaigns to promote healthy diet, increasing taxes on foods that contain added sugars, subsidies to promote accessibility to fruit and vegetables, and strict food industry regulation to reduce sugar intake in children and adolescents, cannot be overemphasized.

Abstract
Background: Liver transplantation leads to non-alcoholic fatty liver disease or non-alcoholic steatohepatitis in up to 40% of graft recipients. The aim of our study was to assess transcriptomic profiles of liver grafts and to contrast the hepatic gene expression between the patients after transplantation with vs. without graft steatosis. Methods: Total RNA was isolated from liver graft biopsies of 91 recipients. Clinical characteristics were compared between steatotic (n = 48) and control (n = 43) samples. Their transcriptomic profiles were assessed using Affymetrix HuGene 2.1 ST Array Strips processed in Affymetrix GeneAtlas. Data were analyzed using Partek Genomics Suite 6.6 and Ingenuity Pathway Analysis. Results: The individuals with hepatic steatosis showed higher indices of obesity including weight, waist circumference or BMI but the two groups were comparable in measures of insulin sensitivity and cholesterol concentrations. We have identified 747 transcripts (326 upregulated and 421 downregulated in steatotic samples compared to controls) significantly differentially expressed between grafts with vs. those without steatosis. Among the most downregulated genes in steatotic samples were P4HA1, IGF1, or fetuin B while the most upregulated were PLIN1 and ME1. Most influential upstream regulators included HNF1A, RXRA, and FXR. The metabolic pathways dysregulated in steatotic liver grafts comprised blood coagulation, bile acid synthesis and transport, cell redox homeostasis, lipid and cholesterol metabolism, epithelial adherence junction signaling, amino acid metabolism, AMPK and glucagon signaling, transmethylation reactions, and inflammation-related pathways. The derived mechanistic network underlying major transcriptome differences between steatotic samples and controls featured PPARA and SERPINE1 as main nodes. Conclusions: While there is a certain overlap between the results of the current study and published transcriptomic profiles of non-transplanted livers with steatosis, we have identified discrete characteristics of the non-alcoholic fatty liver disease in liver grafts potentially utilizable for the establishment of predictive signature.

Abstract
Post-transplant nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH) is common and can be recurrent or de novo. The available data suggest that progression of fibrosis is accelerated in these patients compared to NASH in general population. The long-term data suggest more risk of metabolic syndrome and associated metabolic comorbidities and cardiovascular disease in these patients. The current review focuses on prevalence and prevention/treatment of post-transplant NAFLD or NASH.

Abstract
OBJECTIVE Patients who have undergone transplantation often develop metabolic syndrome (MetS) and de-novo nonalcoholic fatty liver disease (NAFLD). Our aim was to evaluate the impact of metabolic disease on cardiovascular and neoplastic risk and survival. PATIENTS AND METHODS Data from patients who underwent transplantation between 2000 and 2005 in two Italian transplant centers were analyzed. Cox regression analysis was carried out for predictors of de-novo NAFLD and nonalcoholic steatohepatitis (NASH), cardiovascular events, de-novo extrahepatic cancers, and survival. Survival analysis was completed using the Kaplan-Meier method. A P value less than 0.05 was considered significant for all tests. RESULTS De-novo NAFLD was found in one-fifth of 194 patients. Patients with de-novo NAFLD fulfilled the criteria of MetS in 74.4% of cases, while patients without de-novo NAFLD in 29.8% (P=0.000). On multivariate analysis, MetS correlated independently with de-novo NAFLD and this emerged as an independent predictor of cardiovascular events and as a relevant risk factor for solid extrahepatic cancer. Data on smoking habits, which represent a consolidated risk factor for cardiovascular events and cancer in both the general population and patients who have undergone transplantation, are not available. In the subset of histologically proven NASH, it was the strongest predictor of long-term survival (hazard ratio=4.133, 95% confidence interval: 1.385-12.331, P=0.011). CONCLUSION Post-transplant NAFLD represented a strong risk factor for cardiovascular atherosclerotic disease and solid extrahepatic cancer, whereas de novo histologically proven NASH was an independent predictor of long-term mortality.

Abstract
BACKGROUND & AIMS We hypothesized that patients currently diagnosed with cryptogenic cirrhosis (CC) have truly 'cryptogenic' liver disease, which is unlikely to have evolved from NASH. The aim of this study is to characterize patients with CC, and compare their characteristics to patients with cirrhosis of other etiologies. METHODS To investigate this, we compared the clinical characteristics of adults with CC (n = 7,999) to those with cirrhosis caused by non-alcoholic steatohepatitis (NASH) (n = 11,302), alcohol (n = 21,714) and autoimmune hepatitis (n = 3,447), using the UNOS database from 2002-16. We performed an age, gender and year of listing matched comparison of CC and NASH (n = 7,201 in each group), and also stratified patients by the presence of obesity or diabetes mellitus (DM). RESULTS From 2002 to 2016, patients listed with a diagnosis of NASH increased from about 1% to 16% while CC decreased from 8% to 4%. A logistic regression model using the entire United Network for Organ Sharing data (n = 138,021) suggested that the strongest predictors of NASH were type 2 DM, obesity, age ≥60 years, female gender and white race. Type 2 DM was more common in patients with NASH (53%) than those with CC (29%), alcoholic cirrhosis (16%) and autoimmune hepatitis (16%), and obesity was more common in NASH (65.3%) compared to the other three groups (33-42%). There were more white individuals (82.3%) in the NASH group and a lower prevalence of black, Hispanic and Asian individuals, compared to the other three groups. Hepatocellular carcinoma was more commonly seen in NASH (19% vs. 9-13% in the other groups) and this is not influenced by obesity and type 2 DM. The differences between CC and NASH remained unchanged even when two groups were matched for age, gender and year of listing, or when stratified by the presence or absence of obesity or type 2DM. CONCLUSIONS Based on risk perspectives, CC should not be equated with the term 'NASH cirrhosis'. LAY SUMMARY We hypothesized that cryptogenic cirrhosis is a distinct condition from cirrhosis caused by non-alcoholic steatohepatitis (NASH). By comparing cryptogenic cirrhosis with cirrhosis of other causes, we found clear clinical differences. Therefore, cryptogenic cirrhosis should not be considered the same as NASH cirrhosis. Further investigations are required to identify unknown causes of cirrhosis.

Abstract
The number of transplants caused by nonalcoholic fatty liver disease/nonalcoholic steatohepatitis (NASH) has been progressively increasing and this is expected to become the most common indication for liver transplant in the United States. Patients with NASH show many features of the metabolic syndrome and, as a result, are at higher risk for postoperative cardiovascular morbidity and mortality. Despite this, patients with NASH have long-term graft and patient survival rates comparable with other causes of chronic liver disease. Posttransplant metabolic syndrome is a common occurrence that increases the risk of steatosis in the graft liver.

Nonalcoholic fatty liver disease (NAFLD) is a major cause of chronic liver disease worldwide, and its clinical and economic burden will continue to grow with parallel increases in rates of obesity, diabetes, and the metabolic syndrome. Evolving understanding of the natural history of NAFLD suggests that these patients are at risk for disease progression to steatohepatitis, fibrosis, and cirrhosis. Recent studies also suggest that these patients are at elevated risk for cardiovascular-, malignancy-, and liver-related morbidity and mortality, although their risk for progression, decompensation, and hepatocellular carcinoma may be less than that of patients with alternative causes of chronic liver disease.

Abstract
The focus in liver transplantation in the next 10 years will likely change from preventing viral disease recurrence to minimizing the toll of rejection and fatty liver disease, minimizing the complications from immunosuppression with withdrawal strategies, and more optimal management of long-term risks, such as malignancy, cardiovascular disease, and renal failure. In addition, now that short-term results (<1 year) have improved significantly, there will be a shift toward improving long-term patient and graft survival, as well as a focus on primary care preventive strategies.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in developing countries. Approximately 25% of patients with NAFLD develop nonalcoholic steatohepatitis (NASH). NASH-related cirrhosis is now a leading listing indication for liver transplantation in the United States. Although posttransplant survival for NASH-related cirrhosis is comparable with that of other liver diseases, many patients have features of metabolic syndrome, which can contribute to a recurrence of NAFLD or NASH. This article reviews the epidemiology, pathophysiology, and treatment of de novo and recurrence of NASH after liver transplantation.

Abstract
INTRODUCTION Metabolic syndrome is associated with increased risk of cardiovascular events, which contributes to the elevated mortality rate among liver transplant recipients. The objective of this systematic review and meta-analysis was to assess the prevalence and risk factors for metabolic syndrome after liver transplantation. METHODS The databases Medline and Scopus were searched for observational studies evaluating prevalence and risk factors for metabolic syndrome after liver transplantation. Meta-analyses were performed based on odds ratios (ORs) from multivariable analyses. The Newcastle-Ottawa Scale was used for assessment of bias. RESULTS The literature search generated 1815 records of which 16 articles were included comprising 3539 patients. The post-transplant prevalence of metabolic syndrome was 39%. Eight studies were eligible for meta-analyses, which showed that pre-transplant diabetes (OR=3.54, 95% confidence interval (CI): 2.51-4.98) and pre-transplant obesity (OR=2.44, 95% CI: 1.48-4.03) were risk factors for metabolic syndrome. Six out of seven studies reported that recipients with metabolic syndrome had a higher incidence of cardiovascular events. Four studies showed that survival was not affected by metabolic syndrome. CONCLUSIONS The prevalences of metabolic syndrome and new-onset metabolic syndrome were high after liver transplantation. Metabolic syndrome was associated with cardiovascular events, but not poorer survival. Patients with pre-transplant diabetes and -obesity are at high risk of metabolic syndrome and should be under careful surveillance in order to prevent, earlier diagnose, and treat metabolic syndrome and thereby limit the risk of cardiovascular events.

Abstract
BACKGROUND Nonalcoholic steatohepatitis (NASH) is known to recur following liver transplantation (LT). Metabolic risk factors increase with immunosuppression. However, the rate of fibrosis progression following LT for NASH while on immunosuppression is less clear. AIM The incidences of steatosis, NASH, and fibrosis following LT for NASH were quantified and compared with those transplanted for alcoholic liver disease (ALD). PATIENTS AND METHODS Records of all NASH patients and 1 : 2 match with ALD transplant recipients between 2001 and 2006 were reviewed retrospectively. Patients without liver biopsies beyond 2 months following LT were excluded. RESULTS NASH patients (n=77) were older (P=0.0006) and less likely male (P<0.001) than ALD patients (n=108). The incidence of steatosis, NASH, and fibrosis stage increased at 1, 3, and 5 years in both groups. Although steatosis and nonalcoholic fatty liver disease activity scores were higher, fibrosis was lower in NASH compared with ALD (0.43 vs. 1.0 stage/year; P=0.0045). The incremental increase in the rate of fibrosis was faster in the first year compared with 4-5 years (0.8 vs. 0.04 stage/year) following LT. The rate of fibrosis progression during 4-5 years was decreased in NASH compared with ALD recipients (0.04 vs. 0.33 stage/year; P=0.015). NASH etiology was associated with reduced rate of fibrosis progression (odds ratio=0.67) on multivariate analysis. CONCLUSION Despite having more steatosis and inflammation, progression of fibrosis was slower in NASH compared with ALD recipients. Fibrosis progression slows with time following LT on immunosuppression and approximates the pretransplant progression rate by year 5.

Abstract
Liver transplantation is an effective and widely used therapy for several patients with acute and chronic liver diseases. The discrepancy between the number of patients on the waiting list and available donors remains the key issue and is responsible for the high rate of waiting list mortality. The recent news is that the majority of patients with hepatitis C virus related liver disease will be cured by new antivirals therefore we should expect soon a reduction in the need of liver transplantation for these recipients. This review aims to highlight, in two different sections, the main open issues of liver transplantation concerning the current and future strategies to the best use of limited number of organs. The first section cover the strategies to increase the donor pool, discussing the use of older donors, split grafts, living donation and donation after cardiac death and mechanical perfusion systems to improve the preservation of organs before liver transplantation. Challenges in immunosuppressive therapy and operational tolerance induction will be evaluated as potential tools to increase the survival in liver transplant recipients and to reducing the need of re-transplantation. The second section is devoted to the evaluation of possible new indications to liver transplantation, where the availability of organs by implementing the strategies mentioned in the first section and the reduction in the number of waiting transplants for HCV disease is realized. Among these new potential indications for transplantation, the expansion of the Milan criteria for hepatocellular cancer is certainly the most open to question.

Abstract
Because of global epidemics of obesity and type 2 diabetes, the prevalence of non-alcoholic fatty liver disease (NAFLD) is increasing both in Europe and the United States, becoming one of the most frequent causes of chronic liver disease and predictably, one of the leading causes of liver transplantation both for end-stage liver disease and hepatocellular carcinoma. For most transplant teams around the world this will raise many challenges in terms of pre- and post-transplant management. Here we review the multifaceted impact of NAFLD on liver transplantation and will discuss: (1) NAFLD as a frequent cause of cryptogenic cirrhosis, end-stage chronic liver disease, and hepatocellular carcinoma; (2) prevalence of NAFLD as an indication for liver transplantation both in Europe and the United States; (3) the impact of NAFLD on the donor pool; (4) the access of NAFLD patients to liver transplantation and their management on the waiting list in regard to metabolic, renal and vascular comorbidities; (5) the prevalence and consequences of post-transplant metabolic syndrome, recurrent and de novo NAFLD; (6) the alternative management and therapeutic options to improve the long-term outcomes with particular emphasis on the correction and control of metabolic comorbidities.

Abstract
Improved surgical techniques and greater efficacy of new anti-rejection drugs have significantly improved the survival of patients undergoing orthotopic liver transplantation (OLT). This has led to an increased incidence of metabolic disorders as well as cardiovascular and cerebrovascular diseases as causes of morbidity and mortality in OLT patients. In the last decade, several studies have examined which predisposing factors lead to increased cardiovascular risk (i.e., age, ethnicity, diabetes, NASH, atrial fibrillation, and some echocardiographic parameters) as well as which factors after OLT (i.e., weight gain, metabolic syndrome, immunosuppressive therapy, and renal failure) are linked to increased cardiovascular mortality. However, currently, there are no available data that evaluate the development of atherosclerotic damage after OLT. The awareness of high cardiovascular risk after OLT has not only lead to the definition of new but generally not accepted screening of high risk patients before transplantation, but also to the need for careful patient follow up and treatment to control metabolic and cardiovascular pathologies after transplant. Prospective studies are needed to better define the predisposing factors for recurrence and de novo occurrence of metabolic alterations responsible for cardiovascular damage after OLT. Moreover, such studies will help to identify the timing of disease progression and damage, which in turn may help to prevent morbidity and mortality for cardiovascular diseases. Our preliminary results show early occurrence of atherosclerotic damage, which is already present a few weeks following OLT, suggesting that specific, patient-tailored therapies should be started immediately post OLT.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the liver injury most often associated with disorders of insulin resistance, including obesity, diabetes and the metabolic syndrome. The term encompasses several patterns of liver injury, including a relatively benign condition of steatosis without hepatocellular injury, nonalcoholic steatohepatitis (NASH), and a pattern of zone 1 steatosis, inflammation and fibrosis mainly observed in prepubertal children. Staging and grading systems have been developed to characterize the histological changes in NAFLD, mainly as a tool for clinical research. The histological features of NAFLD across these different manifestations and the scoring systems used to evaluate disease severity are discussed.

Abstract
Non-alcoholic steatohepatitis is a growing liver-related health problem. In Europe, non-alcoholic fatty liver disease is the most usual reason of chronic liver illness while steatohepatitis, its progressive form, affects 1% of Europeans and North Americans. In the United States steatohepatitis-related cirrhosis is one of the main indications for liver transplant. A targeted stratification for patients waiting for transplant and affected by this disease is mandatory especially because of their increased cardiovascular and cancer risk. The adequate treatment of NAFLD is crucial for the reduction of the disease related morbidity and mortality. In post-transplant setting, the recurrent or de novo steatosis might seriously affect the allograft short- and long-term outcome. Many conditions can represent the basis of the post-transplant steatohepatitis: obesity, hyperlipidaemia, diabetes mellitus, arterial hypertension, immunosuppressant treatment, alcoholic habit and liver graft steatosis. Today, the only consolidated therapy is represented by a deep life-style intervention since the use of drug-based alternative strategies is still limited and a very few data are available for the post-transplant period. Targeted and personalized behaviour and pharmacological interventions have to be developed for both the pre- and post-transplant phase.

Abstract
Steatosis occurs frequently after liver transplantation (LT). We aimed to determine the prevalence of steatosis in adult LT recipients, to determine the effects of significant (>33%; grades 2-3) steatosis on patient survival, and to identify risk factors for the development of significant steatosis and its effect on fibrosis progression. We retrospectively examined 2360 posttransplant biopsies of 548 LT recipients. Survival was compared between patients with significant steatosis and those with grades 0-1 steatosis. Patients with significant steatosis were compared to controls without steatosis (grade 0) for clinical and laboratory factors and fibrosis progression. Steatosis was found in 309 (56.4%) patients, including 93 (17.0%) patients with significant steatosis. Steatohepatitis (nonalcoholic fatty liver disease activity score ≥ 5) was diagnosed in 57 (10.4%) patients. The prevalence of steatosis increased from 30.3% at 1 year to 47.6% at 10 years after LT (P < 0.001). Survival times did not differ between groups (P = 0.29). On multivariate analysis of pretransplant factors and initial immunosuppression (IS), alcohol-induced cirrhosis (P < 0.001) and high body mass index (BMI; P = 0.002) were associated with the development of significant steatosis, whereas increased levels of alkaline phosphatase (P = 0.01) and mycophenolate mofetil given initially (P = 0.009) appeared to protect against significant steatosis. On multivariate analysis of posttransplant factors, high BMI (P < 0.001), serum triglycerides (P < 0.001), alcohol consumption (P = 0.005), and type 2 diabetes mellitus (P = 0.048) were associated with significant steatosis, whereas high creatinine (P = 0.02) appeared to protect against significant steatosis. Significant steatosis was not associated with a higher fibrosis stage (P = 0.62). Posttransplant steatosis affects 56.4% of LT recipients, and the prevalence increases with time after LT. Recipient factors and types of IS affect the risk for significant steatosis, which is not associated with a higher fibrosis stage or worse patient survival.
