Abstract
Patients submitted to liver transplantation (LT) are exposed to high risk of cardiovascular (CV) complications which are the main determinants of both short-term and long-term morbidity and mortality in LT. Non-alcoholic fatty liver disease (NAFLD) is a very frequent condition in general population and is associated with a high risk of cardiovascular disease (CVD) which represents the first cause of death of these patients. NAFLD is predicted to become the first indication to LT and nowadays is also frequently detected in patients submitted to LT for other indications. Thus, the risk of CVD in patients submitted to LT is forecasted to increase in the next years. In this review the extent of CV involvement in patients submitted to LT and the role of NAFLD, either recurring after transplantation or as de novo presentation, in increasing CV risk is analysed. The risk of developing metabolic alterations, including diabetes, hypertension, dyslipidemia and weight gain, all manifestations of metabolic syndrome, occurring in the first months after LT, is depicted. The different presentations of cardiac involvement, represented by early atherosclerosis, coronary artery disease, heart failure and arrhythmias in patients with NAFLD submitted to LT is described. In addition, the tools to detect cardiac alterations either before or after LT is reported providing the possibility for an early diagnosis of CVD and an early therapy able to reduce morbidity and mortality for these diseases. The need for long-term concerted multidisciplinary activity with dietary counseling and exercise combined with drug treatment of all manifestations of metabolic syndrome is emphasized.

Abstract
Importance Non-alcoholic fatty liver disease (NAFLD) is a rapidly growing cause of chronic liver disease and is becoming a leading cause of hepatocellular carcinoma (HCC) in many developed countries. This presents major challenges for the surveillance, diagnosis and treatment of HCC. Objective To discuss the clinical challenges faced by clinicians in managing the rising number of NAFLD-HCC cases. Evidence Review MEDLINE, PubMed and Embase databases were searched using the keywords; NAFLD, HCC, surveillance, hepatectomy, liver transplantation, percutaneous ablation, transarterial chemoembolization (TACE), selective internal radiotherapy treatment (SIRT) and sorafenib. Relevant clinical studies were included. Findings Current HCC surveillance programmes are inadequate because they only screen for HCC in patients with cirrhosis, whereas in NAFLD a significant proportion of HCC develops in the absence of cirrhosis. Consequently NAFLD patients often present with a more advanced stage of HCC, with a poorer prognosis. NAFLD-HCC patients also tend to be older and to have more co-morbidities compared to HCC of other etiologies. This limits the use of curative treatments such as liver resection and orthotopic liver transplantation (OLT). Evidence suggests that although NAFLD-HCC patients who undergo liver resection or OLT have worse perioperative and short-term outcomes, overall long-term survival is comparable to HCC of other etiologies. This highlights the importance of careful patient selection, pre-habilitation and perioperative planning for NAFLD-HCC patients being considered for surgical treatment. Careful consideration is also important for non-surgical treatments, although the evidence supporting treatment selection is frequently lacking, as these patients tend to be poorly represented in clinical trials. Locoregional therapies such as percutaneous ablation and TACE may be less well tolerated and less effective in NAFLD patients with obesity or diabetes. The tyrosine kinase inhibitor sorafenib may also be less effective. Conclusions and Relevance This review highlights how international guidelines, for which NAFLD traditionally has made up a small part of the evidence base, may not be appropriate for all NAFLD-HCC patients. Future guidelines need to reflect the changing landscape of HCC, by making specific recommendations for the management of NAFLD-HCC.

Abstract
Non-alcoholic fatty liver disease is a very common medical condition, driven by a combination of genetic and lifestyle factors, ultimately producing a severe chronic liver disease and increased cardiovascular risk. Most people are asymptomatic for a long time, and their daily life is unaffected, leading to difficulty in identifying and managing people who slowly progress to non-alcoholic steatohepatitis (NASH), NASH-cirrhosis, and eventually hepatocellular carcinoma. Despite advances in the understanding of pathogenic mechanisms and the identification of liver fibrosis as the strongest factor in predicting disease progression, no specific treatments have been approved by regulatory agencies. Outside controlled trials, treatment is generally limited to lifestyle intervention aimed at weight loss. Pioglitazone remains the drug of choice to reduce progression of fibrosis in people with diabetes, although it is often used off-label in the absence of diabetes. Vitamin E is mainly used in children and may be considered in adults without diabetes. Several drugs are under investigation according to the agreed targets of reduced NASH activity without worsening of fibrosis or improving fibrosis without worsening of NASH. Anti-inflammatory, anti-fibrotic agents and metabolism modulators have been tested in either phase III or phase IIb randomized controlled trials; a few failed, and others have produced marginally positive results, but only a few are being tested in extension studies. The development of non-invasive, easily repeatable surrogate biomarkers and/or imaging tools is crucial to facilitate clinical studies and limit liver biopsy.

Abstract
Nonalcoholic fatty liver disease is the leading cause of liver disease worldwide. It has expansive extrahepatic morbidity and mortality including increased rates of both cardiovascular disease and venous thromboembolism. Derangements in primary, secondary and tertiary hemostasis are found in nonalcoholic fatty liver disease independent of those ascribed to end-stage liver disease. The abnormalities across all stages of hemostasis explain the increased rates of clinically relevant thrombotic events, including pulmonary embolism, deep vein thrombosis and portal vein thrombosis, which on an epidemiologic basis appears to be independent of obesity and other traditional venous thromboembolic risk factors. However, given the complex interaction between obesity, body composition and nonalcoholic fatty liver disease and the potential for exercise to benefit all three, more research is needed to further define the role of each in contributing to the prohemostatic state of nonalcoholic fatty liver disease in order to improve patient oriented outcomes.

Abstract
The liver transplantation (LT) population is aging, with the need for transplant being driven by the growing prevalence of nonalcoholic steatohepatitis (NASH). Older LT recipients with NASH may be at an increased risk for adverse outcomes after LT. Our objective is to characterize outcomes in these recipients in a large multicenter cohort. All primary LT recipients ≥65 years from 2010 to 2016 at 13 centers in the Re-Evaluating Age Limits in Transplantation (REALT) consortium were included. Of 1023 LT recipients, 226 (22.1%) were over 70 years old, and 207 (20.2%) had NASH. Compared with other LT recipients, NASH recipients were older (68.0 versus 67.3 years), more likely to be female (47.3% versus 32.8%), White (78.3% versus 68.0%), Hispanic (12.1% versus 9.2%), and had higher Model for End-Stage Liver Disease-sodium (21 versus 18) at LT (P < 0.05 for all). Specific cardiac risk factors including diabetes with or without chronic complications (69.6%), hypertension (66.3%), hyperlipidemia (46.3%), coronary artery disease (36.7%), and moderate-to-severe renal disease (44.4%) were highly prevalent among NASH LT recipients. Graft survival among NASH patients was 90.3% at 1 year and 82.4% at 3 years compared with 88.9% at 1 year and 80.4% at 3 years for non-NASH patients (log-rank P = 0.58 and P = 0.59, respectively). Within 1 year after LT, the incidence of graft rejection (17.4%), biliary strictures (20.9%), and solid organ cancers (4.9%) were comparable. Rates of cardiovascular (CV) complications, renal failure, and infection were also similar in both groups. We observed similar posttransplant morbidity and mortality outcomes for NASH and non-NASH LT recipients. Certain CV risk factors were more prevalent in this population, although posttransplant outcomes within 1 year including CV events and renal failure were similar to non-NASH LT recipients.

Transplant Outcomes in Older Patients With Nonalcoholic Steatohepatitis Compared to Alcohol-related Liver Disease and Hepatitis C. Transplantation 2020; 104:e164-e173. [PMID: 32150036 DOI: 10.1097/tp.0000000000003219] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/27/2022]
Abstract
BACKGROUND Patients with nonalcoholic steatohepatitis (NASH) are waitlisted at older ages than individuals with other liver diseases, but the effect of age on liver transplantation (LT) outcomes in this population and whether it differs from other etiologies is not known. We aimed to evaluate the impact of age on LT outcomes in NASH. METHODS The United Network for Organ Sharing database was used to identify adults with NASH, hepatitis C virus (HCV) infection, and alcohol-related liver disease (ALD) listed for LT during 2004-2017. Patients were split into age groups (18-49, 50-54, 55-59, 60-64, 65-69, ≥70), and their outcomes were compared. RESULTS From 2004 to 2017, 14 197 adults with NASH were waitlisted, and the proportion ≥65 increased from 15.8% to 28.9%. NASH patients ages 65-69 had an increased risk of waitlist and posttransplant mortality compared to younger groups, whereas the outcomes in ages 60-64 and 55-59 were similar. The outcomes of individuals with NASH were similar to patients of the same age group with ALD or HCV. Functional status and dialysis were predictors of posttransplant mortality in individuals ≥65 with NASH, and cardiovascular disease was the leading cause of death. CONCLUSIONS Older NASH patients (≥65) have an increased risk of waitlist and posttransplant mortality compared to younger individuals, although outcomes were similar to patients with ALD or HCV of corresponding age. These individuals should be carefully evaluated prior to LT, considering their functional status, renal function, and cardiovascular risk. Further studies are needed to optimize outcomes in this growing population of transplant candidates.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a serious health concern as it can progress to liver cirrhosis and hepatoma. We investigated past trends in the prevalence of NAFLD and related factors among Korean men and women from 1998 to 2017 and predicted their future prevalence among Korean men. We used data from the Korea National Health and Nutrition Examination Survey I–VII (KNHANES). NAFLD was defined as a hepatic steatosis index of >36. Subjects with viral hepatitis, liver cirrhosis, cancer, pregnancy, and a habit of drinking ≥30 g alcohol per occasion were excluded. We evaluated the prevalence trends of NAFLD, obesity, abdominal obesity, high fat intake, and low physical activity in each KNHANES wave. For future prevalence predictions, average annual percentage changes (AAPCs) were estimated from the joinpoint model. In men, NAFLD prevalence has increased by approximately 11 percentage points in the past 19 years, reaching 30.7% in wave VII. Prevalence of obesity, abdominal obesity, high fat intake, and low physical activity also increased. The AAPC of NAFLD prevalence was 2.3% per year, and the estimated NAFLD prevalence in 2030 and 2035 was 39.1% and 43.8%, respectively. The forecasted prevalence of obesity, abdominal obesity, and high fat intake among Korean men in 2035 was 65.0%, 52.2%, and 23.5%, respectively. The estimated future prevalence of NAFLD and related factors was considerably high in the younger age group (19–45 year). In women, NAFLD prevalence has increased by approximately three percentage points in the past 19 years; however, this increase was not significant in the multivariate analysis. Public strategies to manage obesity, abdominal obesity, and unhealthy lifestyles are needed to prevent NAFLD.

Abstract
Non-alcoholic steatohepatitis (NASH) is the most common chronic liver disease worldwide, and the fastest growing indication for liver transplantation in the United States. NASH is now the leading etiology for liver transplantation in women, the second leading indication for men, and the most common cause amongst recipients aged 65 years and older. Patients with end-stage liver disease related to NASH represent a unique and challenging patient population due the high incidence of associated comorbid diseases, including obesity, type 2 diabetes (T2D), and hypertension. These challenges manifest in the pre-liver transplantation period with increased waitlist times and waitlist mortality. Furthermore, these patients carry considerable risk of morbidity and mortality both before after liver transplantation, with high rates of T2D, cardiovascular disease, chronic kidney disease, poor nutrition, and disease recurrence. Successful transplantation for these patients requires identification and management of their comorbidities in the face of liver failure. Multidisciplinary evaluations include a thorough pre-transplant workup with a complete cardiac evaluation, control of diabetes, nutritional support, and even, potentially, consultation with a bariatric surgeon. This article provides a comprehensive review of the conditions and challenges facing patients with NASH cirrhosis undergoing liver transplantation and provides recommendations for evaluation and management to optimize them before liver transplantation to produce successful outcomes.

Abstract
Along with the obesity epidemic there has been a major increase in non-alcoholic fatty liver disease (NAFLD) prevalence, paralleling a steady increase in cirrhosis of the liver and hepatocellular cancer (HCC) related to NAFLD. Currently, NAFLD (related HCC and cirrhosis) is the second most common cause for liver transplantation (LT) and it is projected to take the top spot in the next 3-5 years. Patients with NAFLD cirrhosis and HCC have a unique set of comorbidities which potentially increases their risk for cardiovascular disease (CVD) and mortality. However, a review of the published data in NAFLD patients who undergo LT, does not paint a clear picture. While CVD is the most common cause of non-graft related mortality over the long-term, the short and intermediate-term survival post LT in NAFLD cirrhosis appears to be on par with other etiologies when age and comorbidities are factored. The cardiovascular complications are increased in the immediate post-transplant period but there is a shift from ischemic complications to arrhythmias and heart failure (HF). NAFLD recurs in 80-100% patients and occurs de novo in about 50% after LT, potentially impacting their long-term morbidity and mortality. This review summarizes the available data on CVD in NAFLD patients before and after LT, explains what is currently known about the epidemiology and pathogenesis of CVD in NAFLD and posits strategies to improve wait-list and post-transplant survival.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of metabolic syndrome. The spread of obesity worldwide in pandemic proportions has led to a rapid rise of NAFLD in developed and developing countries alike. There are no approved pharmacological agents to treat steatohepatitis or advanced fibrosis but obeticholic acid recently has shown some promise in phase III trial. Currently, NAFLD is the number one etiology for simultaneous liver and kidney transplantation in the USA, second most common indication for liver transplantation (LT) and projected to become number one very soon. LT for NAFLD poses unique challenges, as these patients are generally older, obese and more likely to have a number of metabolic risk factors. Bariatric surgery is an option and can be considered if a structured weight loss program does not achieve the sustained weight loss goal. Comprehensive cardiovascular risk assessment and aggressive management of comorbid conditions are crucial in the LT evaluation process to improve post-transplant survival. Recurrent nonalcoholic steatohepatitis after LT is not uncommon, and thus warrants primary and secondary prevention strategies through a multidisciplinary approach. Prevalence of NAFLD in a donor population is a unique and growing concern that limits the access to quality liver grafts.

Abstract
Organ transplantation as an option to overcome end-stage diseases is common in countries with advanced healthcare systems and is increasingly provided in emerging and developing countries. A review of the literature points to sex- and gender-based inequity in the field with differences reported at each step of the transplant process, including access to a transplantation waiting list, access to transplantation once waitlisted, as well as outcome after transplantation. In this review, we summarize the data regarding sex- and gender-based disparity in adult and pediatric kidney, liver, lung, heart, and hematopoietic stem cell transplantation and argue that there are not only biological but also psychological and socioeconomic issues that contribute to disparity in the outcome, as well as an inequitable access to transplantation for women and girls. Because the demand for organs has always exceeded the supply, the transplant community has long recognized the need to ensure equity and efficiency of the organ allocation system. In the spirit of equity and equality, the authors call for recognition of these inequities and the development of policies that have the potential to ensure that girls and women have equitable access to transplantation.

Abstract
GOALS The aim of this study was to perform a comprehensive assessment of liver transplant (LT) outcomes among US adults with a specific focus on understanding race/ethnicity-specific disparities. BACKGROUND Despite improvements in the liver allocation and LT-related care, disparities in LT outcomes persist. STUDY Using data from the 2005 to 2016 United Networks for Organ Sharing LT registry, we evaluated waitlist survival, probability of receiving LT, and post-LT survival among US adults stratified by race/ethnicity and liver disease etiology. Kaplan-Meier methods evaluated unadjusted waitlist and post-LT outcomes, and multivariate regression models evaluated adjusted waitlist and post-LT outcomes. RESULTS Among 88,542 listed for LT patients (41.3% hepatitis C virus, 25.3% alcoholic liver disease, 22.3% nonalcoholic steatohepatitis, 11.1% hepatitis C virus/alcoholic liver disease), significant race/ethnicity-specific disparities were observed. Compared with non-Hispanic whites, Hispanics had a significantly lower risk of waitlist death [hazard ratio (HR)=0.84, 95% confidence interval (CI): 0.79-0.90, P<0.001]. Compared with non-Hispanic whites, significantly lower likelihood of receiving LT was observed in African Americans (HR=0.94, 95% CI: 0.91-0.98, P<0.001), Hispanics (HR=0.70, 95% CI: 0.68-0.73, P<0.001) and Asians (HR=0.74, 95% CI: 0.69-0.80, P<0.001). Compared with non-Hispanic whites, African Americans had a significantly higher risk of 5-year post-LT death (HR=1.31, 95% CI: 1.23-1.39, P<0.001). CONCLUSION Among US adults awaiting LT, significant race/ethnicity-specific disparities in LT outcomes were observed. Despite evaluating an era after implementation of the Model for End-Stage Liver Disease, ethnic minorities continue to demonstrate a lower probability of receiving LT, and significantly higher risk of death post-LT in African Americans.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease. Nonalcoholic steatohepatitis (NASH) is the clinically aggressive variant of NAFLD and has a propensity for fibrosis progression and cirrhosis. The prevalence of NAFLD and NASH is projected to increase rapidly in the near future and dramatically add to the already substantial health care burden. Cirrhosis and end-stage liver disease resulting from NASH is now the fastest growing indication for liver transplant (LT) in the United States. Patients with NASH cirrhosis have higher prevalence of cardiometabolic diseases. Following LT, recurrence of NAFLD and NASH is common.

Abstract
Nonalcoholic fatty liver disease includes a spectrum of liver disorders that range from simple steatosis to nonalcoholic steatohepatitis (NASH), fibrosis, and cirrhosis. Risk factors such as obesity, hypertension, hyperlipidemia, chronic kidney disease, and smoking status increase risk of progression to cirrhosis among patients with NASH. Cirrhosis derived from non-NASH causes may share similar features with patients with NASH but embody distinct pathogenetic mechanisms, genetic associations, prognosis, and outcomes. This article discusses in detail the comparison of clinical, genetic, and outcome characteristics between patients with NASH cirrhosis as opposed to alternative causes of chronic liver disease.

Abstract
The incidence of non-alcoholic fatty liver disease (NAFLD) is rapidly growing, affecting 25% of the world population. Non-alcoholic steatohepatitis (NASH) is the most severe form of NAFLD and affects 1.5% to 6.5% of the world population. Its rising incidence will make end-stage liver disease (ESLD) due to NASH the number one indication for liver transplantation (LT) in the next 10 to 20 years, overtaking Hepatitis C. Patients with NASH also have a high prevalence of associated comorbidities such as type 2 diabetes, obesity, metabolic syndrome, cardiovascular disease, and chronic kidney disease (CKD), which must be adequately managed during the peritransplant period for optimal post-transplant outcomes. The focus of this review article is to provide a comprehensive overview of the unique challenges these patients present in the peritransplant period, which comprises the pre-transplant, intraoperative, and immediate postoperative periods.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a spectrum of disease, extending from simple steatosis to inflammation and fibrosis with a significant risk for the development of cirrhosis. It is highly prevalent and is associated with significant adverse outcomes both through liver-specific morbidity and mortality but, perhaps more important, through adverse cardiovascular and metabolic outcomes. It is closely associated with type 2 diabetes and obesity, and both of these conditions drive progressive disease toward the more advanced stages. The mechanisms that govern hepatic lipid accumulation and the predisposition to inflammation and fibrosis are still not fully understood but reflect a complex interplay between metabolic target tissues including adipose and skeletal muscle, and immune and inflammatory cells. The ability to make an accurate assessment of disease stage (that relates to clinical outcome) can also be challenging. While liver biopsy is still regarded as the gold-standard investigative tool, there is an extensive literature on the search for novel noninvasive biomarkers and imaging modalities that aim to accurately reflect the stage of underlying disease. Finally, although no therapies are currently licensed for the treatment of NAFLD, there are interventions that appear to have proven efficacy in randomized controlled trials as well as an extensive emerging therapeutic landscape of new agents that target many of the fundamental pathophysiological processes that drive NAFLD. It is highly likely that over the next few years, new treatments with a specific license for the treatment of NAFLD will become available.

Abstract
Currently, nonalcoholic steatohepatitis (NASH) is the second leading indication for liver transplantation (LT), behind alcohol-related liver disease. After transplant, both recurrent and de novo nonalcoholic fatty liver disease are common; however, recurrence rates of NASH and advanced fibrosis are low. Identification of high-risk groups and optimizing treatment of metabolic comorbidities both before and after LT is paramount to maintaining a healthy allograft, especially with the additional consequences of longterm immunosuppression. In addition, NASH LT recipients are at an increased risk of cardiovascular events and malignancy, and their condition warrants a tailored approach to management. The optimal approach to NASH LT recipients including metabolic comorbidities management, tailored immunosuppression, the role of bariatric surgery, and nutritional and pharmacotherapy of NASH are discussed in this review. Overall, aggressive management of metabolic syndrome after LT via medical and surgical modalities and a minimalist approach to immunosuppression is advised.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a major national and international health burden. It is one of the most common liver diseases worldwide and the most common cause of abnormal liver enzymes in many developed countries. Non-alcoholic fatty liver disease is also known as an important cause of cryptogenic cirrhosis and second leading cause for liver transplantation. It is commonly associated with metabolic syndrome. Non-alcoholic steatohepatitis (NASH) is the progressive phenotype of NAFLD. In spite of promising performance of non-invasive tools, liver biopsy remains the gold standard test for NASH diagnosis. Over decades, many drugs have been investigated in phase 2 and 3; however, no approved therapy to date. Despite the alarming global rates of NAFLD, there are no local community-based studies on the prevalence of NAFLD or local practice guidelines on its management; this expert review aims to fill this gap.

Increased Risk of Death in First Year After Liver Transplantation Among Patients With Nonalcoholic Steatohepatitis vs Liver Disease of Other Etiologies. Clin Gastroenterol Hepatol 2019; 17:2759-2768.e5.

Abstract
BACKGROUND & AIMS An increasing number of patients with non-alcoholic steatohepatitis (NASH) require liver transplantation. We compared outcomes of patients with liver diseases of different etiologies (NASH, hepatitis C virus [HCV]-associated liver disease, and alcohol-associated liver disease [ALD]). METHODS We analyzed data from the United Network for Organ Sharing registry on 6344 patients who underwent liver transplantation for NASH, 17,037 for cirrhosis from chronic HCV infection, and 9279 for ALD. We collected data from patients who underwent liver transplantation during the following time periods: 2008-2010, 2011-2013, 2014-2015, 2016-2017. We compared outcomes of different groups using Cox regression models, adjusting for donor and recipient characteristics. RESULTS For patients who underwent liver transplantation during 2016-2017, a significantly lower proportion of patients with NASH survived for 1 year after transplantation than patients with HCV (P = .004) or ALD (P < .001). During this time period, the adjusted risk of death within 1 year was significantly higher for patients with NASH than with ALD (hazard ratio, 1.37; P = .03), regardless of the presence of hepatocellular carcinoma. The effects of increasing age were greatest among patients with NASH: compared to patients younger than 50 years, hazard ratios for overall mortality were 1.31 for patients 50-59 years (P = .02), 1.66 for patients 60-64 years (P < .001), 2.08 for patients 65-69 years (P < .001), and 2.66 and for patients and ≥70 years (P < .001). Mortality from cardiovascular or cerebrovascular disease(s) was highest among patients with NASH, accounting for 11.5% of deaths, compared to 7.0% of deaths in patients with HCV infection and 9.6% in patients with ALD (P < .001). CONCLUSIONS In an analysis of data from patients who underwent liver transplantation during 2016-2017, we found the risk of death within 1 year after transplant was higher among patients with NASH than HCV-associated liver disease or ALD. Risk of death increased with age, and patients with NASH have a higher risk of death from cardiovascular or cerebrovascular disease.

Abstract
BACKGROUND & AIMS Little is known about outcomes of liver transplantation for patients with non-alcoholic steatohepatitis (NASH). We aimed to determine the frequency and outcomes of liver transplantation for patients with NASH in Europe and identify prognostic factors. METHODS We analysed data from patients transplanted for end-stage liver disease between January 2002 and December 2016 using the European Liver Transplant Registry database. We compared data between patients with NASH versus other aetiologies. The principle endpoints were patient and overall allograft survival. RESULTS Among 68,950 adults undergoing first liver transplantation, 4.0% were transplanted for NASH - an increase from 1.2% in 2002 to 8.4% in 2016. A greater proportion of patients transplanted for NASH (39.1%) had hepatocellular carcinoma (HCC) than non-NASH patients (28.9%, p <0.001). NASH was not significantly associated with survival of patients (hazard ratio [HR] 1.02, p = 0.713) or grafts (HR 0.99; p = 0.815) after accounting for available recipient and donor variables. Infection (24.0%) and cardio/cerebrovascular complications (5.3%) were the commonest causes of death in patients with NASH without HCC. Increasing recipient age (61-65 years: HR 2.07, p <0.001; >65: HR 1.72, p = 0.017), elevated model for end-stage liver disease score (>23: HR 1.48, p = 0.048) and low (<18.5 kg/m2: HR 4.29, p = 0.048) or high (>40 kg/m2: HR 1.96, p = 0.012) recipient body mass index independently predicted death in patients transplanted for NASH without HCC. Data must be interpreted in the context of absent recognised confounders, such as pre-morbid metabolic risk factors. CONCLUSIONS The number and proportion of liver transplants performed for NASH in Europe has increased from 2002 through 2016. HCC was more common in patients transplanted with NASH. Survival of patients and grafts in patients with NASH is comparable to that of other disease indications. LAY SUMMARY The prevalence of non-alcoholic fatty liver disease has increased dramatically in parallel with the worldwide increase in obesity and diabetes. Its progressive form, non-alcoholic steatohepatitis, is a growing indication for liver transplantation in Europe, with good overall outcomes reported. However, careful risk factor assessment is required to maintain favourable post-transplant outcomes in patients with non-alcoholic steatohepatitis.

Abstract
Nonalcoholic steatohepatitis (NASH)-related cirrhosis has become one of the most common indications for liver transplantation (LT), particularly in candidates older than 65 years. Typically, NASH candidates have concurrent obesity, metabolic, and cardiovascular risks, which directly impact patient evaluation and selection, waitlist morbidity and mortality, and eventually posttransplant outcomes. The purpose of these guidelines is to highlight specific features commonly observed in NASH candidates and strategies to optimize pretransplant evaluation and waitlist survival. More specifically, the working group addressed the following clinically relevant questions providing recommendations based on the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) system supported by rigorous systematic reviews and consensus: (1) Is the outcome after LT similar to that of other etiologies of liver disease? (2) Is the natural history of NASH-related cirrhosis different from other etiologies of end-stage liver disease? (3) How should cardiovascular risk be assessed in the candidate for LT? Should the assessment differ from that done in other etiologies? (4) How should comorbidities (hypertension, diabetes, dyslipidemia, obesity, renal dysfunction, etc.) be treated in the candidate for LT? Should treatment and monitoring of these comorbidities differ from that applied in other etiologies? (5) What are the therapeutic strategies recommended to improve the cardiovascular and nutritional status of a NASH patient in the waiting list for LT? (6) Is there any circumstance where obesity should contraindicate LT? (7) What is the optimal time for bariatric surgery: before, during, or after LT? (8) How relevant is donor steatosis for LT in NASH patients?

Abstract
Nonalcoholic fatty liver disease (NAFLD) affects 25% of the global adult population with a range of 13.5% in Africa and 31.8% in the Middle East. Nonalcoholic fatty liver disease is closely associated with a constellation of metabolic comorbidities which include: obesity, type 2 diabetes mellitus, hypertension, and hypercholesteremia. In fact, the increasing number of metabolic comorbidities not only increases the prevalence of NAFLD but also places patients at higher risk for progressive liver disease. As such, NAFLD is presently among the top etiologies for hepatocellular carcinoma and an indication for liver transplantation (LT) in the United States. Therefore, the following recommendations are made based on our current knowledge of NAFLD and its consequences: (1) the evaluation of the risk of liver disease progression can be affected by patient's ethnic origin and sex; (2) fibrosis in NAFLD is the most important predictor of mortality; (3) we recommend that individuals who present with features of metabolic syndrome in the presence of elevated liver enzymes should be screened for NAFLD and, more importantly, nonalcoholic steatohepatitis (NASH); (4) we recommend that NAFLD patients, especially those with multiple risk factors, should be screened for cardiovascular diseases and managed accordingly; (5) comorbidities in NAFLD/NASH patients who are considered for LT need to be assessed in the pretransplant and posttransplant settings because these factors can affect waitlist mortality, resource utilization, as well as posttransplant complications, morbidity, and perhaps, mortality; (6) any attempt to decrease the incidence of NAFLD should ideally address the development of obesity in childhood and early adulthood, favoring the adoption of healthy lifestyles through comprehensive health policy programs.

Abstract
PURPOSE OF REVIEW Nonalcoholic fatty liver disease (NAFLD) is a growing cause of chronic liver disease globally and nonalcoholic steatohepatitis is projected to become the most common indication for liver transplantation. The purpose of this review is to highlight key issues surrounding NAFLD as an indication for liver transplantation, including its increasing prevalence, outcomes related to liver transplantation, development of post liver transplant NAFLD and NAFLD in the liver donor pool. RECENT FINDINGS With the advent of direct-acting antiviral therapies, the proportion of patients on the liver transplant list or undergoing liver transplant for chronic hepatitis C infection is steadily decreasing. In contrast, the number transplants performed for NAFLD is increasing. By 2030, it is estimated that the incidence of decompensated cirrhosis and hepatocellular carcinoma will increase by 168 and 137%, respectively, and the number of deaths will increase by 178%. SUMMARY Liver transplantation cures cirrhosis but does not treat the underlying metabolic disease associated with NAFLD. Thus, strategies to control comorbidities in patients with NAFLD prior to transplant are needed to decrease waitlist mortality and the recurrence of NAFLD after liver transplant. NAFLD in the donor pool is also a growing concern. Strategies to minimize steatosis and expand the number of donors are critical to meet the growing demand for liver transplantation.

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
Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide and is associated with hepatocellular carcinoma (HCC), the most frequent malignant liver tumor. The increasing prevalence of obesity and diabetes is influencing the epidemiology of HCC with the most dramatic increases in NAFLD-related HCC seen in Western countries. Although cirrhosis is the major risk factor for HCC in NAFLD, there is increasing recognition that NAFLD-HCC occurs in the absence of cirrhosis. Areas covered: The epidemiology of NAFLD related HCC and its impact on changing the incidence of HCC globally. We overview risk factors for NAFLD-HCC in the presence and absence of cirrhosis and examine trends in liver transplantation (LT) related to NAFLD-HCC. Expert commentary: The incidence of NAFLD-related cirrhosis will continue to rise globally in parallel with risk factors of obesity and diabetes. Consequently, NAFLD-related HCC will become an increasingly important cause of liver-related morbidity and mortality and a common indication for LT worldwide. Further identification of risk factors for NAFLD-HCC and effective treatments for NAFLD are required to reduce this future burden of disease.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide. Patients with NAFLD are at a higher risk of developing cardiovascular disease (CVD). In fact, CVD-related mortality is more common in patients with NAFLD in comparison to liver-related mortality. This association is related to the common metabolic risk factors such as obesity, dyslipidemia, diabetes, and hypertension shared by both NAFLD and CVD, and also there is independent association of NAFLD with CVD because of risk factors such as insulin resistance, systemic inflammation, and atherogenic dyslipidemia. While there is abundant literature on association of NAFLD with CVD, there is sparse literature regarding the screening for CVD in patients with NAFLD. In the current review article, we discuss as to which patients with NAFLD to screen and how to screen for CVD.

Abstract
In parallel with the rising prevalence of metabolic syndrome globally, nonalcoholic fatty liver (NAFL) disease is the most common chronic liver disease in Western countries and nonalcoholic steatohepatitis (NASH) has become increasingly associated with hepatocellular carcinoma. Recent studies have identified NASH as the most rapidly growing indication for liver transplantation (LT). As a hepatic manifestation of the metabolic syndrome, NAFL disease can be histologically divided into NAFL and NASH. NAFL is considered a benign condition, with histological changes of hepatocyte steatosis but without evidence of hepatocellular injury or fibrosis. This is distinct from NASH, which is characterized by hepatocyte ballooning and inflammation, and which can progress to fibrosis and cirrhosis, hepatocellular carcinoma, and liver failure. As for any other end-stage liver disease, LT is a curative option for NASH after the onset of decompensated cirrhosis or hepatocellular carcinoma. Although some studies have suggested increased rates of sepsis and cardiovascular complications in the immediate postoperative period, the long-term posttransplant survival of NASH cases is similar to other indications for LT. Recurrence of NAFL following LT is common and can be challenging, although recurrence rates of NASH are lower. The persistence or progression of metabolic syndrome components after LT are likely responsible for NASH recurrence in transplanted liver. Therefore, while maintaining access to LT is important, concerted effort to address the modifiable risk factors and develop effective screening strategies to identify early stages of disease are paramount to effectively tackle this growing epidemic.

Abstract
BACKGROUND & AIMS Nonalcoholic fatty liver disease(NAFLD) is the second most common cause of liver transplantation in the US. Data on NAFLD as a liver transplantation indication from countries with lower prevalences of obesity are lacking. We studied the temporal trends of NAFLD as an indication for liver transplantation in the Nordic countries, and compared outcomes for patients with NAFLD to patients with other indications for liver transplantation. METHOD Population-based cohort study using data from the Nordic Liver Transplant Registry on adults listed for liver transplantation between 1994 and 2015. NAFLD as the underlying indication for liver transplantation was defined as a listing diagnosis of NAFLD/nonalcoholic steatohepatitis, or cryptogenic cirrhosis with a body mass index ≥25 kg/m2 and absence of other liver diseases. Waiting time for liver transplantation, mortality and withdrawal from the transplant waiting list were registered. Survival after liver transplantation was calculated using multivariable Cox regression, adjusted for age, sex, body mass index and model for end-stage liver disease. RESULTS A total of 4609 patients listed for liver transplantation were included. NAFLD as the underlying indication for liver transplantation increased from 2.0% in 1994-1995 to 6.2% in 2011-2015 (P = .01) and was the second most rapidly increasing indication. NAFLD patients had higher age, model for end-stage liver disease and body mass index when listed for liver transplantation, but overall survival after liver transplantation was comparable to non--NAFLD patients (aHR 1.03, 95% CI 0.70-1.53 P = .87). CONCLUSION NAFLD is an increasing indication for liver transplantation in the Nordic countries. Despite more advanced liver disease, NAFLD patients have a comparable survival to other patients listed for liver transplantation.

Abstract
Liver transplantation (LT) has become the treatment of choice for a wide range of liver diseases in both adult and pediatric patients. Until recently, the largest proportion of LT in adults, were performed in patients with hepatitis C (HCV) related cirrhosis. The recent availability of safe and effective direct antiviral agents to cure HCV infection in almost all patients whatever the HCV genotype and severity of liver disease, will reduce the need for LT in this category of recipients. Thus, it is presumed that in the next 1 to 2 decades HCV related liver disease will diminish substantially, whereas non-alcoholic steato-hepatitis (NASH) will correspondingly escalate as an indication for LT. The greatest challenges facing LT remain the limited supply of donor organs, and the need for chronic immunosuppression, which represent the true obstacles to the greater application and durable success of the LT procedure. This review aimed to highlight, in different sections, the main open issues and future developments in LT. These will be focused to explore current and future strategies to maximize the use of limited organs, to offer an update on potential new approaches to immunosuppression and to imagine new indications for LT when the number of patients awaiting transplants for HCV related liver disease is reduced.

Abstract
Oxidative stress is being recognized as a key factor in the progression of chronic liver disease (CLD), especially non-alcoholic fatty liver disease (NAFLD). Many NAFLD treatment guidelines recommend the use of antioxidants, especially vitamin E. Many prospective studies have described the beneficial effects of such agents for the clinical course of NAFLD. However, as these studies are usually short-term evaluations, lasting only a few years, whether or not antioxidants continue to exert favorable long-term effects, including in cases of concomitant hepatocellular carcinoma, remains unclear. Antioxidants are generally believed to be beneficial for human health and are often commercially available as health-food products. Patients with lifestyle-related diseases often use such products to try to be healthier without practicing lifestyle intervention. However, under some experimental NAFLD conditions, antioxidants have been shown to encourage the progression of hepatocellular carcinoma, as oxidative stress is toxic for cancer cells, just as for normal cells. In this review, we will highlight the paradoxical effects of antioxidants against NAFLD and related hepatocellular carcinoma.

Abstract
UNLABELLED Nonalcoholic fatty liver disease (NAFLD) and its progressive form non-alcoholic steatohepatitis (NASH), are rapidly becoming among the top causes of cirrhosis, hepatocellular carcinoma, and indications for liver transplantation. Other than lifestyle modification through diet and exercise, there are currently no other approved treatments for NASH/NAFLD. Although weight loss can be effective, it is difficult to achieve and sustain. In contrast, bariatric surgery can improve metabolic conditions associated with NAFLD, and has been shown to improve liver histology. To have approved regimens for the treatment of NASH/NAFLD, several issues must be addressed. First, all stakeholders must agree on the most appropriate clinical trial endpoints for NASH. Currently, resolution of NASH (without worsening fibrosis) or reduction of fibrosis stage (without worsening NASH) are the accepted endpoints by the regulatory authorities. It is important to recognize the prognostic implication of histologic features of NASH. In this context, although histologic NASH has been associated with advanced fibrosis, it is not an independent predictor of long-term mortality. In contrast, there are significant data to suggest that fibrosis stage is the only robust and independent predictor of liver-related mortality. In addition to the primary endpoints, several important secondary endpoints, including noninvasive biomarkers, long-term outcomes, and patient-reported outcomes must be considered. In 2018, a few phase 3 clinical trials for the treatment of NASH have been initiated. Additionally, a number of phase 2a and 2b clinical trials targeting different pathogenic pathways in NASH are in the pipeline of emerging therapies. CONCLUSION Over the next 5 years, some of these regimens are expected to provide potential new treatment options for patients with NASH/NAFLD. (Hepatology 2018;68:361-371).

Abstract
Nonalcoholic fatty liver disease/nonalcoholic steatohepatitis (NAFLD/NASH) is a challenging and multisystem disease that has a high socioeconomic impact. NAFLD/NASH is a main cause of macrovesicular steatosis and has multiple impacts on liver transplantation (LT), on patients on the waiting list for transplant, on post-transplant setting as well as on organ donors. Current data indicate new trends in the area of chronic liver disease. Due to the increased incidence of metabolic syndrome (MetS) and its components, NASH cirrhosis and hepatocellular carcinoma caused by NASH will soon become a major indication for LT. Furthermore, due to an increasing incidence of MetS and, consequently, NAFLD, there will be more steatotic donor livers and less high quality organs available for LT, in addition to a lack of available liver allografts. Patients who have NASH and are candidates for LT have multiple comorbidities and are unique LT candidates. Finally, we discuss long-term grafts and patient survival after LT, the recurrence of NASH and NASH appearing de novo after transplantation. In addition, we suggest topics and areas that require more research for improving the health care of this increasing patient population.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is the main cause of liver diseases in Spain and the incidence is raising due to the outbreak of type 2 diabetes and obesity. This CPG suggests recommendation about diagnosis, mainly non-invasive biomarkers, and clinical management of this entity. Life-style modifications to achieve weight loss is the main target in the management of NAFLD. Low caloric Mediterranean diet and 200 minutes/week of aerobic exercise are encouraged. In non-responders patients with morbid obesity, bariatric surgery or metabolic endoscopy could be indicated. Pharmacological therapy is indicated in patients with NASH and fibrosis and non-responders to weight loss measures. NAFLD could influence liver transplantation, as a growing indication, the impact of steatosis in the graft viability, de novo NAFLD rate after OLT and a raised cardiovascular risk that modify the management of this entity. The current CPG was the result of the First Spanish NAFLD meeting in Seville.

Abstract
GOALS To analyze the frequency and trend of liver transplantation (LT) for nonalcoholic steatohepatitis (NASH) cirrhosis in young adults aged 18 to 40 years and to assess post-LT outcomes in this age group. BACKGROUND NASH is currently the fastest-growing indication for LT in US adults. It is believed that NASH is a rare indication for LT among young adults. STUDY Using the United Network for Organ Sharing database, we performed a retrospective cohort analysis of all LTs in young adults between 2002 and 2012. Incidence rate ratio was calculated for each indication. RESULTS A total of 5157 young adults underwent LT over the study period-54% were male, 23% obese. Mean (±SD) age and body mass index were 31.6±6.7 years and 26.3±6.1 kg/m, respectively. The incidence of LTs performed for NASH cirrhosis increased from 0.53% in 2002 to 4.46% in 2012. NASH was the most rapidly growing indication for LT among all other etiologies with a 14% increment per year (incidence rate ratio, 1.14; 95% confidence interval, 1.09-1.20, P<0.001). The 5-year post-LT outcomes were comparable between NASH and non-NASH recipients, but graft survival was lower and retransplantation cumulative rates were higher in NASH recipients compared with those with other metabolic liver diseases (63.5% vs. 81.4%, P=0.003 and 12.7% vs. 4.2%, P=0.046, respectively). CONCLUSIONS NASH is the fastest-growing indication for LT among young US adults aged 18 to 40 years and now accounts for almost 5% of all LTs in this age group.

Abstract
Patients after orthopic liver transplantation (OLT) are at risk of developing graft dysfunction. Sphingolipids (SL’s) have been identified to play a pivotal role in the regulation of hepatocellular apoptosis, inflammation and immunity. We aimed to investigate the serum SL profile in a prospective real-world cohort of post-OLT patients. From October 2015 until July 2016, 149 well-characterized post-OLT patients were analyzed. SL’s were assessed in serum probes via Liquid Chromatography/Tandem Mass Spectrometry. Twenty-nine (20%) patients had a biopsy proven graft rejection with decreased C20-ceramide (Cer) (p = 0.042), C18-dihydroceramide (DHC) (p = 0.022) and C24DHC (p = 0.060) levels. Furthermore, C18DHC (p = 0.044) and C24DHC (p = 0.011) were significantly down-regulated in patients with ischemic type biliary lesions (ITBL; n = 15; 10%). One-hundred and thirty-three patients (89%) have so far received tacrolimus as the main immunosuppressive agent with observed elevations of C14Cer (p = 0.052), C18Cer (p = 0.049) and C18:1Cer (p = 0.024). Hepatocellular carcinoma (HCC) pre-OLT was associated with increases in C24:1Cer (p = 0.024) and C24:1DHC (p = 0.024). In this large prospective cross-sectional study of patients, post-OLT serum levels of (very-)long chain (dihydro-)ceramides associate with graft rejection, ITBL, tacrolimus intake and HCC pre-OLT. Hence, serum SL’s may be indicative of graft complications. Further research is necessary to identify their diverse mechanistic role in regulating immunity and inflammation in patients post-OLT.

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.

Abstract
The pandemic of obesity and its related complications is rapidly changing the epidemiology of many types of cancer, including hepatocellular carcinoma (HCC). Non-alcoholic fatty liver disease (NAFLD) is becoming a major cause of HCC, with a steadily rising trend compared to viral or alcohol-induced chronic hepatitis. The much greater prevalence of the underlying liver disease in the general population and the chance of HCC occurrence in non-cirrhotic liver are the most worrisome aspects of HCC in NAFLD. Effective screening programmes are currently hampered by limited knowledge of the pathways of carcinogenesis and a lack of tools able to stratify the risk of HCC in the NAFLD population. Hence, poor surveillance has prevented the development of an adequate treatment for NAFLD-related HCC. Systemic and hepatic molecular mechanisms involved in hepatocarcinogenesis, as well as potential early markers of HCC are being extensively investigated. This review describes the current clinical impact of HCC in NAFLD and discusses the most important unmet needs for its effective management.

Abstract
BACKGROUND Non-alcoholic steatohepatitis (NASH) is an emerging indication for liver transplantation (LT) and coexists with multiple comorbidities. Obese and cirrhotic patients experience more perioperative complications. Limited data exist about short-term complications after LT for NASH cirrhosis. AIM Investigate short-term complications in patients transplanted for NASH cirrhosis. METHODS Single center retrospective cohort study including patients >18years who underwent LT between 2009-2015. Exclusion criteria were LT for acute liver failure and non-cirrhotic disease. Post-operative complications and severity within 90-days were classified using the Clavien-Dindo classification of surgical complications and comprehensive complication index (CCI). P<0.05 was significant. RESULTS Out of 169 eligible patients, 34 patients (20.1%) were transplanted for NASH cirrhosis. These patients were significantly older (59.2 vs. 54.8 years, P=0.01), more obese (61.8% vs. 8.1%, P<0.01), had more diabetes mellitus (73.5% vs. 20%, P<0.01), metabolic syndrome (83.3% vs. 37.8%, P<0.01) and cardiovascular disease (29.4% vs. 11.1%, P<0.01). More grade 1 complications (OR 1.64, 95%CI 1.03-2.63, P=0.04) and more grade 2 urogenital infections (OR 3.4, 95%CI 1.1-10.6, P=0.03) were found. Major complications, CCI, 90-day mortality and graft survival were similar. CONCLUSION Despite significantly increased comorbidities in patients transplanted for NASH cirrhosis, major morbidity, mortality and graft survival after 90days were comparable to patients transplanted for other indications.

Abstract
BACKGROUND This study evaluates long-term outcomes and body mass index (BMI) following liver transplantation (LT) for non-alcoholic fatty liver disease (NAFLD) in comparison with alcoholic liver disease (ALD). METHODS Patient and graft survival were compared using Kaplan Meier curves and log rank test. Multivariable analysis of recipient and donor characteristics was performed as determinants of patient survival. BMI at listing was compared with BMI post-LT. RESULTS Patient survival at 1-, 3-, 5- and 10 years post-LT was similar in the ALD group (n = 195) compared with the NAFLD group (n = 84) (93% vs. 93%, 91% vs. 89%, 86% vs. 77%, 64% vs. 66% respectively, p = 0.21). One patient in the NAFLD group was re-transplanted and none in the ALD group therefore graft survival was also similar (p = 0.20). Multivariable analysis didn't identify any significant predictors of reduced survival. In comparison with the ALD group, BMI was significantly higher in the NAFLD group at listing (31 vs. 27, p < 0.001), 3-months post-LT (28 vs. 26, p < 0.05) and 6-months post-LT (29 vs. 27, p < 0.05) but was equivalent by 5-years post-LT (29 vs. 30, p = 0.80). CONCLUSIONS NAFLD patients had similar patient and graft survival post-LT compared to ALD. NAFLD patients returned to listing BMI by one-year post-LT but by 5-years post-LT there was no difference in BMI between the groups.

Abstract
Nonalcoholic fatty liver disease is becoming the leading cause of disease resulting in liver transplantation (LT). As a result of this trend, more LT candidates are presenting with prior history of bariatric surgery (BS). Over the last decade, 960 patients underwent LT at our institution; 11 (1.1%) had prior BS. The most common type of BS was Roux-en-Y gastric bypass (n = 9) with 1 sleeve gastrectomy and 1 jejunoileal bypass. A total of 9 patients underwent LT alone, and 2 underwent simultaneous liver-kidney transplantation. The most common indication for LT was nonalcoholic steatohepatitis (n = 10) with 5 having additional diagnosis of alcoholic liver disease. The 30-day reoperation rate was 36.4% (n = 4); indications were bile duct repair (n = 3) and wound repair (n = 1). In the first 6 months after LT, biliary complications were seen in 54.5% (n = 6) of the patients. Both patient and graft survival rates at 1 and 2 years were 81.8% (n = 9) and 72.7% (n = 8), respectively. A total of 8 patients (72.7%) had indications for liver biopsy after LT; significant macrovesicular steatosis was found in 2 (18.2%). In patients with a history of alcohol consumption, 2 (40.0%) relapsed after LT. Two patients (18.2%) had a history of diet-controlled diabetes before LT; 1 of these patients became insulin dependent after LT. Mean body mass index (BMI) at LT was 31.0 ± 5.7 kg/m2 . Mean BMI at 1, 6, and 12 months after LT was 28.3 ± 5.8, 28.0 ± 3.2, and 31.0 ± 6.6 kg/m2 , respectively. Mean preoperative albumin was 2.6 ± 0.6 mg/dL. Patients showed improvement in albumin after LT, with mean albumin of 2.7 ± 0.6 and 3.2 ± 0.5 mg/dL at 1 and 3 months, respectively. The liver profile was stable after LT, with mean aspartate aminotransferase of 32.9 ± 18.4 and 26.6 ± 19.8 IU/L and alanine aminotransferase of 28.0 ± 17.5 and 30.2 ± 17.0 IU/L at 6 and 12 months, respectively. In conclusion, outcomes of LT patients with prior BS are comparable with other transplant recipients with regards to patient and graft survival and post-LT complication rates.

Abstract
OBJECTIVES To assess the long-term cost-effectiveness of a risk stratification pathway, compared with standard care, for detecting non-alcoholic fatty liver disease (NAFLD) in primary care. SETTING Primary care general practices in England. PARTICIPANTS Adults who have been identified in primary care to have a risk factor for developing NAFLD, that is, type 2 diabetes without a history of excessive alcohol use. INTERVENTION A community-based pathway, which uses transient elastography and hepatologists to stratify patients at risk of NAFLD, has been implemented and demonstrated to be feasible (NCT02037867). Earlier identification could mean earlier treatments, referral to specialist and enrolment into surveillance programmes. DESIGN The impact of earlier detection and treatment with the risk stratification pathway on progression to later stages of liver disease was examined using decision modelling with Markov chains to estimate lifetime health and economic effects of the two comparators. DATA SOURCES Data from a prospective cross-sectional feasibility study indicating risk stratification pathway and standard care diagnostic accuracies were combined with a Markov model that comprised the following states: no/mild liver disease, significant liver disease, compensated cirrhosis, decompensated cirrhosis, hepatocellular carcinoma, liver transplant and death. The model data were chosen from up-to-date UK sources, published literature and an expert panel. OUTCOME MEASURE An incremental cost-effectiveness ratio (ICER) indicating cost per quality-adjusted life year (QALY) of the risk stratification pathway compared with standard care was estimated. RESULTS The risk stratification pathway was more effective than standard care and costs £2138 per QALY gained. The ICER was most sensitive to estimates of the rate of fibrosis progression and the effect of treatment on reducing this, and ranged from -£1895 to £7032/QALY. The risk stratification pathway demonstrated an 85% probability of cost-effectiveness at the UK willingness-to-pay threshold of £20 000/QALY. CONCLUSIONS Implementation of a community-based risk stratification pathway is likely to be cost-effective. TRIAL REGISTRATION NUMBER NCT02037867, ClinicalTrials.gov.

Yonsei Med J 2017; 58:756-762. [PMID: 28540988 PMCID: PMC5447106 DOI: 10.3349/ymj.2017.58.4.756] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2016] [Revised: 03/20/2017] [Accepted: 03/21/2017] [Indexed: 12/25/2022] Open
Abstract
PURPOSE Insulin resistance (IR) has an important role in the development of non-alcoholic steatohepatitis (NASH). We aimed to analyze the association between liver histopathology and IR in pediatric patients with NASH. MATERIALS AND METHODS In 24 children with non-alcoholic fatty liver disease (NAFLD), we investigated whether the hepatic pathologic characteristics have relations with following three biochemical indices; IR index including homeostasis model assessment of IR (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), and insulin sensitivity indices-free fatty acid (ISI-FFA). RESULTS Among 24 patients, 16 (66.6%) had a high NAFLD activity score (NAS), which is diagnostic of NASH. Higher serum triglyceride level was significantly correlated with a high NAS. Higher steatosis grades were significantly associated with low insulin sensitivity (p=0.023). In addition, severe lobular inflammation was associated with higher IR: HOMA-IR (p=0.014) and QUICKI (p=0.023). Severe fibrosis correlated with low insulin sensitivity and high IR indexes: ISI-FFA (p=0.049), HOMA-IR (p=0.028), and QUICKI (p=0.007). CONCLUSION Patients with high IR had more severe lobular inflammation and hepatic fibrosis. Analyses of biochemical and endocrine parameters can be applied to determine the severity of the hepatic pathologic status in patients with NASH, especially in children who cannot undergo a liver biopsy.
