Abstract
The increasing prevalence of diabetes mellitus, obesity, and metabolic syndrome in the population can lead to metabolic dysfunction-associated steatohepatitis (MASH) and metabolic dysfunction-associated steatotic liver disease (MASLD). In Western industrialized countries, this has become a major problem with significant socioeconomic impacts. MASH is now a leading cause of liver transplantation (LT), especially in developed countries. However, the post-transplant outcomes of such patients are a major concern, and published data are limited and extremely variable. In this article, we discuss graft and patient survival after LT, complications, the recurrence of MASH, and MASH appearing de novo after transplantation. Recent studies suggest that patients with MASH have slightly worse short-term survival, potentially due to increased cardiovascular mortality. However, most studies found that longer-term outcomes for patients undergoing LT for MASH are similar or even better than those for other indications. Hepatocellular carcinoma due to MASH cirrhosis also has similar or even better outcomes after LT than other etiologies. In conclusion, we suggest questions and topics that require further research to enhance healthcare for this growing patient population.

Post-transplantation outcome in non-alcoholic steatohepatitis cirrhosis: Comparison with alcoholic cirrhosis. Ann Hepatol 2020; 18:855-861. [PMID: 31543468 DOI: 10.1016/j.aohep.2019.06.014] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2018] [Revised: 05/26/2019] [Accepted: 01/29/2019] [Indexed: 02/04/2023]
Abstract
INTRODUCTION AND OBJECTIVES Non-alcoholic steatohepatitis (NASH) indication of liver transplant (LT) has increased recently, whereas alcoholic cirrhosis remains a major indication for LT. To characterize NASH-related cases and to compare the post-transplant outcome of these two conditions represents our major objective. MATERIAL AND METHODS Patients undergoing LT for NASH between 1997 and 2016 were retrieved. Those transplanted between 1997 and 2006 were compared to an "age and LT date" matched group of patients transplanted for alcoholic cirrhosis (ratio 1:2). Baseline features and medium-term outcome measures were compared. RESULTS Of 1986 LT performed between 1997 and 2016, 40 (2%) were labeled as NASH-related indications. NASH-related cases increased initially (from 0.8% in 1997-2001 to 2.7% in 2002-2006) but remained stable in subsequent years (2.3%). Hepatocellular carcinoma (HCC) prevalence was greater in NASH-vs alcohol-related cirrhosis (40% vs 3%, p=0.001). The incidence of overweight, obesity, arterial hypertension, dyslipidemia, diabetes, hyperuricemia, renal insufficiency and cardiovascular (CV) disease was similar in both groups at 5 years post-LT. Five-year survival was higher in NASH but without reaching statistical significance (83% vs 72%, p=0.21). The main cause of mortality in NASH-LT patients was HCC recurrence. CONCLUSION Most previously considered cryptogenic cases are actually NASH-cirrhosis. While the incidence of this indication is increasing in many countries, it has remained relatively stable in our Unit, the largest LT center in Spain. HCC is common in these patients and represents a main cause of post-transplant mortality. Metabolic complications, CV-related disease and 5-yr survival do not differ in patients transplanted for NASH vs alcohol.

Abstract
Nonalcoholic steatohepatitis is the fastest-growing indication for the liver transplant and a leading cause of hepatocellular carcinoma among patients listed for liver transplantation in the USA. Post-transplant nonalcoholic hepatic steatosis and steatohepatitis are frequent complications of liver transplantation. Nonalcoholic steatohepatitis poses a significant challenge in both pre- and post-transplant period due to its association with metabolic syndrome, coronary artery disease, chronic kidney disease, and obstructive sleep apnea. While optimal therapy is not yet available in the post-liver transplant setting, lifestyle interventions continue to remain as the mainstay of therapy for post-transplant nonalcoholic steatohepatitis. Early recognition with protocol biopsies and noninvasive modalities, along with modification of known risk factors, are the most effective methods to curtail the progression of nonalcoholic steatohepatitis in the absence of FDA-approved pharmacologic therapy.

Abstract
The etiology and incidence of cirrhosis in adults has been well studied, however there is scant data in younger patients. The aim of this study was to determine causes of cirrhosis in patients ≤40 years old. In this multi-institutional retrospective study, pathology databases were searched for patients ≤40-year-old with a diagnosis of cirrhosis from 1995 to 2018. Clinical charts and pathology reports were reviewed to identify etiologies of cirrhosis in each case. The patients were divided into 4 age groups (<1, 1- < 5, 5- < 18, and 18-40 years old) for further analysis. We identified 594 patients (264 female, 330 male). Among <18-year-old patients, congenital cholestatic diseases and developmental disorders were the most common causes of cirrhosis (50.2%, 172/342). Metabolic and genetic diseases were also seen more commonly in this age group (16.6%, 57/342). In contrast, viral hepatitides were the most common cause of cirrhosis in 18-40-year-old patients (39.6%, 100/252) followed by autoimmune and fatty liver disease (22.2%, 56/252 and 15.07%, 38/252, respectively). Cryptogenic cirrhosis (overall 7.2%, 42/594) was seen in 3% (4/133), 1.4% (1/69), 10.7% (15/140) and 8.7% (22/252) of patients aged <1, 1- < 5, 5- < 18, and 18-40 years, respectively. Developmental and metabolic disorders are the most common causes of cirrhosis in children (<18), while viral hepatitides are leading causes in adolescents and young adults (18-40) similar to adults. The incidence of cryptogenic cirrhosis also varies depending on the age, being lowest in 1- < 5 year and highest in 5- < 18 year age group children.

Abstract
Background Primary hepatic angiosarcoma is a non-epithelial malignancy derived from sinusoidal endothelial cells, accounting for approximately 1.8% of primary hepatic malignancies. Diagnosis of primary hepatic angiosarcoma is complicated by difficulties in the qualitative radiological assessment of these tumors. Prognosis is very poor due to local recurrence and distant metastasis after liver resection or liver transplantation (LT). Case presentation This case report describes two patients with primary hepatic angiosarcoma who were diagnosed by histopathological examination of the explanted liver after LT. One patient had undergone living donor LT, and the other had undergone deceased donor LT. Neither showed evidence of malignancy on the pre-operative imaging tests. Conclusions Hepatic angiosarcoma has a very high relapse rate after LT. Pre-transplant liver biopsy may be necessary to distinguish diffuse hepatic angiosarcoma from tumors of other origin in patients with cryptogenic liver failure.

Abstract
OBJECTIVES Cryptogenic cirrhosis is a common indication for liver transplantation. Diagnosis is made after exclusion of other causes of cirrhosis. In this study, the aim was to evaluate patients with cryptogenic cirrhosis after histopathological examination of explanted liver. MATERIALS AND METHODS A retrospective histopathological chart review of 117 patients with cryptogenic cirrhosis who had liver transplantation between November 2009 and June 2014 was performed. Age, sex, operative features, survival rates, and preoperative and postoperative diagnosis were evaluated. RESULTS During the study period, 123 liver transplantations were performed for these 117 patients. Deceased donor liver transplantations were performed in 23 (18.7%) of the cases. Retransplantations were performed in 5 patients. Median age was 48 years, and female-to-male ratio was 41:76. Hepatosteatosis were observed in 29 patients. Nonalcoholic fatty liver disease and nonalcoholic steatohepatitis were observed in 20 (12%) and 9 (7.7%) of these patients, respectively. Autoimmune hepatitis was observed in 2 patients. The definitive cause of cirrhosis was unclear in 68 (58%) of the patients. Incidental malignant and premalignant lesions were observed in 15 patients. CONCLUSIONS Histopathological examination of the explanted liver after liver transplantation in those patients with cryptogenic cirrhosis may significantly help to diagnose the cause of cirrhosis, such as nonalcoholic steatohepatitis or autoimmune hepatitis, with using the scoring system developed by the International Autoimmune Hepatitis Workgroup. In addition, incidental malignant or premalignant lesions may be observed.

Abstract
BACKGROUND Liver biopsy (LB) has been used as diagnostic modality in liver diseases (LD). Over last two decades, there has been remarkable improvement in understanding of natural history, molecular diagnostics of viral hepatitis, genetic of LD, and also limitations of LB. There is current trend in avoiding LB in the management of various LDs. AIM To determine utility of LB in clinical practice. MATERIAL AND METHODS In a prospective study, 2413 patients of LD were followed up, 219 (9%) were acute, and remaining 2194 (90.9%) were chronic LD. Patients were evaluated by biochemical parameters, virological studies, and imaging endoscopy as and when required. LB was performed in 176 (7.2%) patients when no conclusion could be drawn from the noninvasive workup. Patients with platelet count <50,000/cm(2), ascites, and overt bleeding were excluded. Patients with international normalization ratio (INR) more than 1.5 were not excluded. No prophylactic use of fresh frozen plasma and platelet transfusion was done. There was no major complication related to the procedure. Indications for LB were as follows: cryptogenic LD 38 cases, hepatitis B infection 35, suspected autoimmune hepatitis 30, mass lesion in the liver and lymphoma 29, evaluation of portal hypertension 15, elevated liver enzymes 11, hepatitis C infection 9, and drug-induced LD 4, and miscellaneous 5 cases which were primary biliary cholangitis, primary sclerosing cholangitis, cholestatic LD, sarcoidosis, and amyloidosis. RESULTS LB changed the diagnosis in 55 (31.2%). These were cryptogenic LD in 24 cases, portal hypertension 15, elevated liver enzymes 11, and 5 others. In remaining, LB confirmed clinical diagnosis and helped in making management decisions. CONCLUSION LB was required in 7.2% of patients with chronic LD. In 31.2% cases, LB changed the diagnosis. LB was a safe procedure even in presence of low platelet count and abnormal INR.

Abstract
AIM The number of patients referred for liver transplantation (LT) with non-alcoholic steatohepatitis (NASH) continues to increase, but information about living donor liver transplantation (LDLT) for NASH is scarce. We conducted this study to document the details of LDLT for NASH in a Japanese LT center. METHODS Among all LDLT recipients in our institution from March 1996 to March 2013 (n = 425), we identified seven patients that underwent LDLT for NASH. RESULTS Of all the seven recipients, most of the patients (86%) were obese. The median follow-up period post-LDLT was 5.3 years. All were alive at the last follow-up. Recurrent NASH was detected in one patient (14%), and no recurrent hepatic steatosis was detected among the remaining six recipients on prospectively performed ultrasonography. No significant comorbidities were observed following donor surgery among the respective living donors during the follow-up period. We also retrospectively reviewed 22 patients with NASH-related end-stage liver disease (ESLD) who were evaluated but rejected for LDLT during the same period. The reasons for rejection for LDLT were presumably associated with the nature of NAFLD/NASH in either potential recipients or donors. CONCLUSION The post-transplant outcome of LDLT for NASH-related ESLD in our institution was feasible, although the sample size was small. Further studies in a larger patient cohort are warranted to investigate the long-term outcome of LDLT for NASH, both for recipients and living donors.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a potential long-term complication after liver transplantation (LT) and can occur as recurrent disease in patients undergoing transplantation for NAFLD or as de novo NAFLD in others. The aim of this study was to compare these 2 different entities. From a cohort of adult patients undergoing transplantation between 2000 and 2010, we selected all patients with a diagnosis of NAFLD made during liver biopsy examinations during post-LT follow-up; clinical, biological, and histological features of patients with recurrent NAFLD and patients with de novo NAFLD were compared. The diagnosis of post-LT NAFLD was made for 91 patients during the study period: 11 cases were classified as recurrent NAFLD, and 80 cases were classified as de novo NAFLD. The groups were not statistically different with respect to the sex ratio, age, prevalence of hypercholesterolemia, prevalence of obesity, or prevalence of hypertension. The prevalence of diabetes mellitus was higher in patients with recurrent NAFLD (100% versus 37.5%, p < 0.01). At 5 years, severe fibrosis (stage 3 or 4) and steatohepatitis were more frequent in patients with recurrent NAFLD versus patients with de novo NAFLD [71.4% versus 12.5% (P < 0.01) and 71.4% versus 17.2% (P < 0.01), respectively]. NAFLD was already present in 67% of the patients with de novo NAFLD and in 100% of the patients with recurrent NAFLD after 1 year. According to successive liver biopsies, steatosis disappeared in 18 patients (22.5%) with de novo NAFLD and in none of the patients with recurrent NAFLD. In conclusion, our results strongly suggest that recurrent NAFLD and de novo NAFLD after LT are different entities; recurrent NAFLD appears to be a more severe and irreversible disease with an earlier onset.

Abstract
CONTEXT In about 10% of patients with chronic liver disease, it is not possible to identify an etiologic factor. These cases are called cryptogenic cirrhosis. Currently, nonalcoholic steatohepatitis (NASH) is being considered as a possible etiologic factor for a significant segment of patients that presents with cryptogenic cirrhosis. OBJECTIVE To estimate the prevalence of risk factors for NASH in patients with cryptogenic cirrhosis, in order to verify if there is a causal relationship between them. METHOD Cross-sectional study, with evaluation of the demographic and laboratorial data of patients with cryptogenic cirrhosis. They were compared with data obtained from a group with NASH and a group with alcoholic and/or hepatitis C (HCV) cirrhosis. RESULTS Forty seven patients with cryptogenic cirrhosis were evaluated, 47 with NASH and 196 with HCV and/or alcoholic cirrhosis. The mean age of patients with cryptogenic cirrhosis was 52 years, while in those with NASH it was 46.4 years (P = 0,041). The group with cryptogenic cirrhosis had 23 female and 24 male patients. Of the patients who presented with NASH, 68.1% were female. Of the patients who presented with alcoholic/HCV cirrhosis, 64.8% were male. There were no statistically significant differences between the groups. In cryptogenic cirrhosis patients, the following prevalences could be observed: impaired fasting glycemia - 68.2%; obesity - 27.5%; total hypercholesterolemia - 27.9%; low HDL levels - 58.1% (women - 81%; men - 36.4%); hypertriglyceridemia - 16.3%. The results seen in cryptogenic cirrhosis patients showed statistical similarity with the results of the NASH group regarding fasting glycemia (62.8%) and male HDL levels (53.8%). The comparison with the alcoholic/HCV cirrhosis group showed statistical differences regarding fasting glycemia (45.2%), hypercholesterolemia (13.3%) and female HDL levels (50.8%). CONCLUSIONS It is not possible to establish a causal relationship between cryptogenic cirrhosis and NASH. Only data related to fasting glycemia and HDL levels in male patients showed statistical similarities between both groups of patients.

Abstract
OBJECTIVE To analyze incidence, outcomes, and utilization of health care resources in liver transplantation (LT) for nonalcoholic steatohepatitis (NASH). SUMMARY OF BACKGROUND DATA With the epidemic of obesity and metabolic syndrome in nearly 33% of the US population, NASH is projected to become the leading indication for LT in the next several years. Data on predictors of outcome and utilization of health care resources after LT in NASH is limited. METHODS We conducted an analysis from our prospective database of 144 adult NASH patients who underwent LT between December 1993 and August 2011. Outcomes and resource utilization were compared with other common indications for LT. Independent predictors of graft and patient survival were identified. RESULTS The average Model for End-Stage Liver Disease score was 33. The frequency of NASH as the primary indication for LT increased from 3% in 2002 to 19% in 2011 to become the second most common indication for LT at our center behind hepatitis C. NASH patients had significantly longer operative times (402 vs 322 minutes; P < 0.001), operative blood loss (18 vs 14 packed red blood cell units; P = 0.001), and posttransplant length of stay (35 vs 29 days; P = 0.032), but 1-, 3-, and 5-year graft (81%, 71%, 63%) and patient (84%, 75%, 70%) survival were comparable with other diagnoses. Age greater than 55 years, pretransplant intubation, dialysis, hospitalization, presence of hepatocellular carcinoma on explant, donor age greater than 55 years, and cold ischemia time greater than 550 minutes were significant independent predictors of survival for all patients, whereas body mass index greater than 35 was a predictor in NASH patients only. CONCLUSIONS We report the largest single institution experience of LT for NASH. Over a 10-year period, the frequency of LT for NASH has increased 5-fold. Although outcomes are comparable with LT for other indications, health care resources are stressed significantly by this new and increasing group of transplant candidates.

Abstract
Nonalcoholic steatohepatitis (NASH) is the progressive form of nonalcoholic fatty liver disease (NAFLD) and is the fourth most common indication for liver transplantation. Risk factors for NAFLD can persist and even worsen after liver transplantation. However, the risk and significance of NAFLD recurrence remain unclear. Reported posttransplant NAFLD and NASH recurrence rates vary widely across studies. There is little information detailing the histological evolution of NAFLD recurrence, and the long-term natural history of NAFLD recurrence is unclear. In this review, we summarize the findings of studies on the prevalence of recurrent NAFLD and its risk factors in the posttransplant setting, and we explore reasons for the discrepant reported recurrence rates. On the basis of currently available data, the relatively low rates of advanced fibrosis and NAFLD-associated graft loss and the comparability of the survival rates for these patients and patients undergoing transplantation for other diseases suggest that although NAFLD or NASH can recur, the clinical significance of disease recurrence for graft or patient survival may be small.

Abstract
Autoimmune hepatitis has a variable clinical phenotype, and the absence of conventional autoantibodies does not preclude its diagnosis or need for treatment. The goals of this review are to describe the frequency and nature of autoantibody-negative autoimmune hepatitis, indicate its outcome after corticosteroid treatment, and increase awareness of the diagnosis in patients with unexplained acute and chronic hepatitis. The frequency of presumed autoantibody-negative autoimmune hepatitis in patients with acute and acute severe presentations is ≤7%, and its frequency in patients with chronic presentations is 1-34%. Patients with acute presentations can have normal serum γ-globulin levels, centrilobular zone 3 necrosis, and low pre-treatment international diagnostic scores. Liver tissue examination is essential for the diagnosis, and hepatic steatosis can be a co-morbid feature. The comprehensive international scoring system can support but never override the clinical diagnosis pre-treatment, and non-standard serological markers should be sought if the clinical diagnosis is uncertain or the diagnostic score is low. A 3-month treatment trial with corticosteroids should be considered in all patients, regardless of the serological findings, and improvements have occurred in 67-87% of cases. Autoantibody-negative autoimmune hepatitis may be associated with an autoantibody outside the conventional battery; it may have a signature autoantibody that is still undiscovered, or its characteristic autoantibodies may have been suppressed or have a delayed expression. The pathogenic mechanisms are presumed to be identical to those of classical disease. Autoantibody-negative autoimmune hepatitis is an infrequent but treatable disease that must be considered in unexplained acute and chronic hepatitis.

Abstract
Cryptogenic chronic hepatitis is a disease that is unexplained by conventional clinical, laboratory and histological findings, and it can progress to cirrhosis, develop hepatocellular carcinoma, and require liver transplantation. The goals of this review are to describe the changing phenotype of cryptogenic chronic hepatitis in adults, develop a diagnostic algorithm appropriate to current practice, and suggest treatment options. The frequency of cryptogenic hepatitis is estimated at 5.4%. Cryptogenic cirrhosis is diagnosed in 5-30% of patients with cirrhosis, and it is present in 3-14% of adults awaiting liver transplantation. Nonalcoholic fatty liver disease has been implicated in 21-63% of patients, and autoimmune hepatitis is a likely diagnosis in 10-54% of individuals. Viral infections, hereditary liver diseases, celiac disease, and unsuspected alcohol or drug-induced liver injury are recognized infrequently in the current cryptogenic population. Manifestations of the metabolic syndrome heighten the suspicion of nonalcoholic fatty liver disease, and the absence of hepatic steatosis does not discount this possibility. The diagnostic scoring system of the International Autoimmune Hepatitis Group can support the diagnosis of autoimmune hepatitis in some patients. Certain genetic mutations may have disease-specificity, and they suggest that some patients may have an independent and uncharacterized disease. Corticosteroid therapy is effective in patients with autoimmune features, and life-style changes and specific therapies for manifestations of the metabolic syndrome are appropriate for all obese patients. The 1- and 5-year survivals after liver transplantation have ranged from 72-85% to 58-73%, respectively.

Abstract
BACKGROUND That non-cirrhotic portal fibrosis (NCPF) can lead to end stage chronic liver disease (CLD) has been convincingly demonstrated only recently after the study of explant livers from clinically cirrhosis cases. AIMS This study attempted to determine the frequency of NCPF among adults transplanted for end stage CLD and to identify parameters for a pre-transplant diagnosis of NCPF. METHODS Several parameters were analyzed in three categories of cases: pure NCPF (n = 10), overlap NCPF (n = 10), and NAFLD cirrhosis controls (n = 44). Morphologic features of NCPF were looked for in explant livers of all these. RESULTS Explant livers in the pure NCPF group were non-cirrhotic and showed histologic features of NCPF. These features were also present in all cases of overlap NCPF in the background of established cirrhosis of other etiologies but absent in the NAFLD cirrhosis controls. Values of seven objective and two subjective parameters showed significant differences between pure NCPF and NAFLD control groups. Compared to NAFLD controls, the model for end stage liver disease (MELD) score, body mass index (BMI), bilirubin, albumin, aspartate amino transferase (AST), and international normalized ratio (INR) were significantly less, whereas variceal grade was higher in the pure NCPF group. CONCLUSIONS The study concludes that in our population, NCPF constitutes about 5% of the subset of end stage CLD considered eligible for liver transplantation (LT), presenting mostly as cryptogenic cirrhosis (CC). A diagnosis of NCPF should be considered when patients presumed to have cryptogenic or other cirrhosis become eligible for LT even in the presence of relatively well-preserved liver function and low MELD scores. End stage CLD manifests at earlier age, when cirrhosis of another etiology supervenes on pre-existent NCPF.

Abstract
Histological analysis of liver biopsies remains a standard against which other methods of assessment for the presence and amount of hepatic injury due to nonalcoholic fatty liver disease (NAFLD) are measured. Histological evaluation remains the sole method of distinguishing steatosis from advanced forms of NAFLD, i.e. nonalcoholic steatohepatitis (NASH) and fibrosis. Included in the lesions of NAFLD are steatosis, lobular and portal inflammation, hepatocyte injury in the forms of ballooning and apoptosis, and fibrosis. However, patterns of these lesions are as distinguishing as the lesions themselves. Liver injury in adults and children due to NAFLD may have different histological patterns. In this review, the rationale for liver biopsy, as well as the histopathological lesions, the microscopically observable patterns of injury, and the differential diagnoses of NAFLD and NASH are discussed.

Abstract
OBJECTIVES Non-alcoholic fatty liver disease (NAFLD), autoimmune hepatitis (AIH) and unapparent alcohol abuse may be underlying causes of cryptogenic cirrhosis, but the frequencies of these underlying factors differ between studies. Also, previous studies have shown various outcomes after orthotopic liver transplantation (OLT) for cryptogenic cirrhosis. The aims of this study were (1) to evaluate the presence of NAFLD in patients with cryptogenic cirrhosis evaluated for OLT and (2) to compare the severity of liver disease and patient survival in OLT candidates with cryptogenic cirrhosis and those with cirrhosis of another known origin. MATERIAL AND METHODS Four-hundred and seventy adult patients with end-stage liver cirrhosis evaluated for OLT between 1990 and 2004 were included, of whom 39 had cryptogenic cirrhosis. Clinical, histological and laboratory data that had been prospectively collected were re-evaluated. RESULTS Seventeen (44%) of the cryptogenic patients had NAFLD in a previous liver biopsy and/or clinical features of the metabolic syndrome. Two patients had occult alcohol over-consumption and one patient had burnt-out AIH. Cryptogenic patients had significantly higher frequencies of diabetes, ascites, and hyponatraemia and weight loss. Patient survival was similar between cryptogenic patients and cirrhotics with a known aetiology. CONCLUSIONS Re-evaluation of patient data discovered probable underlying aetiologies in 51% of patients with cryptogenic cirrhosis evaluated for OLT, of which NAFLD was the most common (44%). Although cryptogenic patients had a more advanced liver disease when evaluated for OLT, patient survival was similar. Recent weight loss was significantly more common in cryptogenic patients, possibly being a sign of liver decompensation and signalling a need for OLT evaluation.

Abstract
In a proportion of liver cirrhosis, the etiology continues to remain elusive. It is uncertain whether and to what extent cirrhosis evolving from nonalcoholic fatty liver disease contributes to this group of cryptogenic cirrhosis because the clinicopathologic features of nonalcoholic fatty liver disease cirrhosis are largely unknown. We explored these facets by examining the explant livers and clinical data in living donor liver transplant recipients. Among 103 adult liver transplant recipients with different types of chronic liver disease, 30 had a pre-liver transplant diagnosis of cryptogenic cirrhosis. A final categorization of the native liver disease was attempted in these cases on the basis of detail pathomorphological findings in adequately sampled explant liver correlated with careful review of pre-liver transplant clinical data. Of the 30 cryptogenic cirrhosis cases, 19 (63.3%) finally labeled as nonalcoholic fatty liver disease cirrhosis showed histologic features in several respects different from those reported for the early and established phases of nonalcoholic fatty liver disease. Steatosis was infrequent and focal or even absent, whereas variable grades of Mallory hyaline and inflammation were consistently present. Ductular proliferation and hydropic change of hepatocytes were also frequent. Only 9 (47%) of the 19 cases had nonalcoholic fatty liver disease associated risk factors like diabetes and obesity. It was concluded that appreciation of quantitative and qualitative differences in hepatic morphology between the cirrhotic and the early/established stage of nonalcoholic fatty liver disease will help in making a correct diagnosis of nonalcoholic fatty liver disease cirrhosis in the proper clinical setting. When appropriate criteria are used, nonalcoholic fatty liver disease appears to account for close to two thirds of cases currently labeled as cryptogenic cirrhosis.

Abstract
Nonalcoholic steatohepatitis (NASH) is becoming a common cause of liver cirrhosis requiring liver transplantation (LT). Cardiovascular complications related to metabolic syndrome and NASH recurrence in the transplanted liver may affect the outcome of LT in these patients. We compared the outcomes of LT for NASH cirrhosis and alcoholic cirrhosis (ETOH) in a large transplant center. A retrospective chart review was performed for all patients who underwent LT for cryptogenic cirrhosis with the NASH phenotype (the NASH group) or ETOH (the ETOH group) at the University of Miami from January 1997 to January 2007. There was no significant difference in survival between the NASH and ETOH groups, despite a trend toward lower survival in the former (P = 0.1699). Sepsis was the leading cause of posttransplant death in both groups, and it was followed by cardiovascular causes in the NASH group (26% versus 7% in the ETOH group, P = 0.21) and malignancies in the ETOH group (29% versus 0% in the NASH group, P = 0.024). Recurrent steatohepatitis (33% versus 0%, P < 0.0001) and acute rejection (41% versus 23%, P < 0.023) were significantly more frequent in the NASH group than in the ETOH group. There was no difference in graft failure between the groups (24% in the NASH group versus 18% in the ETOH group, P = 0.3973). In conclusion, despite a numerical trend favoring the ETOH group, there were no statistically significant differences in posttransplant survival and cardiovascular mortality between the NASH and ETOH groups. Acute rejection and recurrent steatohepatitis were significantly more frequent in the NASH group but did not lead to higher rates of retransplantation.

Abstract
Recurrence of the original disease following liver transplantation is not uncommon and can lead to graft failure. There are limited data on recurrent fatty liver disease following liver transplantation. The aim of this study was to determine the incidence of recurrent fatty liver disease in patients with biopsy-proven nonalcoholic steatohepatitis, its effect on survival, and whether there are any predictive factors for recurrence. We analyzed patients undergoing liver transplantation for nonalcoholic steatohepatitis cirrhosis from 1997 to 2008 at a single center. Patients undergoing transplantation for cholestatic disease, alcohol, hepatitis C, or cryptogenic cirrhosis were controls. Ninety-eight patients underwent transplantation for nonalcoholic steatohepatitis cirrhosis. Recurrent fatty liver disease was seen in 70%, 25% had recurrent nonalcoholic steatohepatitis, and 18% had stage II/IV or greater fibrosis at a mean of 18 months. No patients with recurrent nonalcoholic steatohepatitis developed graft failure or required retransplantation at a follow-up of 3 years. No recipient or donor factors were associated with disease recurrence, although patients with recurrent nonalcoholic steatohepatitis had a higher incidence of diabetes, weight gain, and dyslipidemia at the time of diagnosis of recurrence. One-third of patients with recurrent nonalcoholic steatohepatitis had normal liver enzymes at the time of diagnosis post-transplantation. In conclusion, recurrent fatty liver disease is common following liver transplantation for nonalcoholic steatohepatitis cirrhosis but does not lead to early allograft failure. Recurrent nonalcoholic steatohepatitis can occur despite normal liver enzymes, and features of metabolic syndrome are associated with disease recurrence.

Abstract
The methionine choline-deficient (MCD) diet results in liver injury similar to human nonalcoholic steatohepatitis (NASH). The aims of this study were to define mechanisms of MCD-induced steatosis in insulin-resistant db/db and insulin-sensitive db/m mice. MCD-fed db/db mice developed more hepatic steatosis and retained more insulin resistance than MCD-fed db/m mice. Both subcutaneous and gonadal fat were reduced by MCD feeding: gonadal fat decreased by 23% in db/db mice and by 90% in db/m mice. Weight loss was attenuated in the db/db mice, being only 13% compared with 35% in MCD-fed db/db and db/m mice, respectively. Both strains had upregulation of hepatic fatty acid transport proteins as well as increased hepatic uptake of [14C]oleic acid: 3-fold in db/m mice (P < 0.001) and 2-fold in db/db mice (P < 0.01) after 4 weeks of MCD feeding. In both murine strains, the MCD diet reduced triglyceride secretion and downregulated genes involved in triglyceride synthesis. Therefore, increased fatty acid uptake and decreased VLDL secretion represent two important mechanisms by which the MCD diet promotes intrahepatic lipid accumulation in this model. Feeding the MCD diet to diabetic rodents broadens the applicability of this model for the study of human NASH.

Abstract
Liver allograft cirrhosis is a relatively uncommon complication of liver transplantation. Most cases can be attributed to disease recurrence, particularly recurrent hepatitis C. Little is known about the frequency, etiology, and natural history of liver allograft cirrhosis occurring without evidence of recurrent disease. The aim of the present study was to review the clinicopathological features in this group of patients. We retrospectively reviewed data from all adult patients who were transplanted between 1982 and 2002 and survived >12 months after orthotopic liver transplantation (n = 1,287). Cases of histologically proven cirrhosis were identified from histopathological data entered into the Liver Unit Database. A total of 48 patients (3.7%) developed cirrhosis. In 29 of them, cirrhosis could be attributed to recurrent disease (hepatitis C, 11; hepatitis B, 4; autoimmune hepatitis, 4; primary biliary cirrhosis, 2; primary sclerosing cholangitis, 3; nonalcoholic steatohepatitis, 4; alcoholic liver disease, 1). In 9 of the 19 patients without evidence of disease recurrence, another cause of cirrhosis could be identified (de novo autoimmune hepatitis, 4; biliary complications, 4; acquired hepatitis B, 1). In the remaining 10 cases, the cause of cirrhosis remained unknown; their previous biopsies had shown features of chronic hepatitis of uncertain etiology. Three patients in this group died, and the remaining 7 are alive with good graft function 3-12 years after cirrhosis was first diagnosed. The prevalence of "cryptogenic" posttransplant cirrhosis was significantly higher in patients initially transplanted for fulminant seronegative hepatitis (6%) than in those transplanted for other diseases (0.3%). In conclusion, posttransplant cirrhosis without disease recurrence is uncommon, but it is more frequent in patients transplanted for fulminant seronegative hepatitis. Chronic hepatitis is the most frequent underlying pathological process in cases where the cause of cirrhosis remains uncertain.

Abstract
Long-term graft survival and mortality after liver transplantation continue to improve. However, disease recurrence remains a major stumbling block, especially among patients with hepatitis C. Chronic hepatitis C recurs to varying degrees in nearly all patients who undergo transplantation. Transplantation for hepatitis C is associated with higher rates of graft failure and death compared with transplantation for other indications, and retransplantation for hepatitis C related liver failure remains controversial. Recurrence of hepatitis B has been markedly reduced with improved prophylactic regimens. Further, rates of hepatocellular carcinoma recurrence have also decreased, as improved patient selection criteria have prioritized transplantation for those with a low risk of recurrence. Primary biliary cirrhosis recurs in some patients, but it is often relatively mild. Autoimmune liver disease has also been shown to have a relatively benign post-transplantation course, but some studies have indicated that it slowly progresses in most recipients. It has been recently reported that alcoholic liver disease liver transplant recipients who return to drinking have worsened mortality. In such patients worse outcomes are not due to graft failure, but instead to other comorbidities. Recurrences of other diseases, including nonalcoholic steatohepatitis and primary sclerosing cholangitis, are now being recognized as having potentially detrimental effects on graft survival and mortality. Expert clinical management may help prevent and treat complications associated with disease recurrence.

Abstract
Cryptogenic cirrhosis (CC), literally meaning cirrhosis of obscure or unknown origin, is a diagnosis of exclusion. The circumstantial evidence indicates that nonalcoholic fatty liver disease (NAFLD) is perhaps one of the important causes of CC. There is also evidence, especially from the European literature, that some patients with CC may have undiagnosed or burnt-out autoimmune hepatitis (AIH). Other rare causes may include "unknown" viral (non-A, non-B, non-C) hepatitis, and occult alcoholism. In this review, we examine the role of NAFLD and other causes in the pathogenesis of CC, and the impact of obesity on patients with chronic liver disease.

Abstract
A condition defined as nonalcoholic fatty liver disease (NAFLD) is frequently found in humans. Deemed as a benign condition until recently, more emphasis is now put on the potential harmful evolution of the inflammatory form, that is, nonalcoholic steatohepatitis (NASH), toward end-stage liver disease. This review highlights the major morphologic and pathophysiological features of NASH. The link between experimental biochemical findings in animal models and clinical and therapeutic approaches in humans is discussed. Once all the other causes of persistent elevation of serum transaminase levels have been excluded, the diagnosis of NASH can be only confirmed by liver histology. Other noninvasive diagnostic tools, however, are being investigated to assess specific subcellular functions and to allow the follow-up of patients at higher risk for major liver dysfunction. A better understanding of various pathogenic aspects of NASH will help in identifying potential therapeutic approaches in these patients.

Abstract
Obesity has emerged as a significant new health problem in the pediatric population. Non-alcoholic steatohepatitis (NASH) is an entity in the spectrum of non-alcoholic fatty liver disease (NAFLD) ranges from fat in the liver -- simple steatosis, NASH/ steatohepatitis -- fat with inflammation and/or fibrosis to advanced fibrosis and cirrhosis when fat may no longer be present. NASH is associated with obesity, diabetes, insulin resistance (IR), and hypertriglyceridemia. While majority of individuals with risk factors like obesity and IR have steatosis only a minority develop steatohepatitis, possible mechanisms have been discussed. Clinical experience with pediatric NASH is limited. Children generally present in the prepubertal age group, have a male predominance with a higher incidence in children of Hispanic origin. Body mass index (BMI) of 25-29.9 is considered to be overweight and that > or =30 obese. Acanthosis nigricans as a marker of IR should be looked for. As NASH is a diagnosis of exclusion, other causes of chronic liver disease must be excluded. Increased echogenicity in the liver is noted on ultrasound. Liver biopsy is considered the gold standard in establishing the diagnosis. Histopathological lesions thought to be necessary for diagnosis of NASH include steatosis (macrovesicular > microvesicular), mixed mild lobular inflammation and hepatocyte ballooning. A system of grading depending on degree of steatosis and/or inflammation and staging depending on the extent of fibrosis has also been proposed. Although there is no consensus for the treatment for NASH, effort needs to be made to prevent development of fibrosis, which results in cirrhosis and portal hypertension. Slow, consistent weight loss has been shown to be effective in childhood NAFLD, based on improvement of serum aminotransferases or liver sonogram. A low glycemic index diet has been shown to be more effective than a low fat diet in lowering BMI. Family based behavioral intervention may also enhance success with diet. Several pharmacological agents have been used including ursodeoxycholic acid, vitamin E, betaine, n-acetyl cysteine, and insulin sensitizing agents like metformin, rosiglitazone, and pioglitazone. Transplantation for overt NASH is rare, accounting for < 1% of liver transplantations in the USA. The disease can recur after liver transplantation. A strong association exists between the presence of steatosis in a donor liver and poor graft function. As a result, cadaveric donor livers with macrovesicular steatosis >40% are not used routinely. Prognosis in NASH is dependent not only on severity and number of risk factors but also on the degree of histological damage. Clinical trials are needed to identify an effective treatment that halts the progression of NAFLD to NASH in both pretransplantation and post-transplantation patients.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a frequent syndrome encompassing fatty liver alone and steatohepatitis (NASH). Often asymptomatic, the suspicion arises because of abnormal aminotransferases or a bright liver on abdominal ultrasound. It should be suspected during evaluation of associated conditions as obesity, diabetes or dyslipidaemia. The diagnostic evaluation must exclude other potential causes of liver disease and may include a liver biopsy, the only method able to confirm features of necroinflammation and fibrosis that define NASH and its prognostic implications. Indeed, the presence of necroinflammation has been associated with a significant risk of progression to cirrhosis and eventually hepatocellular carcinoma. Age >45 years, obesity and diabetes have also been associated with an increased risk of liver fibrosis and progression to cirrhosis. Given the high prevalence of NAFLD, general measures of life-style changes, focusing on exercise, diet, and total alcohol abstinence, should be implemented before a liver biopsy is considered.
