Spontaneous regression of hepatocellular carcinoma: what three cases of regression and disease reoccurrence can tell US.

Hepatocellular carcinoma (HCC) is a highly morbid disease both in the United States and worldwide. Chronic liver inflammation puts people at risk of developing HCC. As chronic liver disease prevalence increases in the United States there can be an expected rise in HCC. Spontaneous regression of HCC is a rare phenomenon but can provide much needed information on how to better understand disease characteristics and progression. The two proposed theories that may explain spontaneous regression are tumor hypoxia and immunologic reaction. In these cases, we describe 3 patients with heavy disease burden at presentation who showed spontaneous regression of cancer. The patient's characteristics correlate most with systemic immunologic reaction resulting in spontaneous regression. Unfortunately, all of these patients had disease recurrence shortly after regression. By studying patient data in cases of spontaneous regression, we can gain a better understanding of disease progression and which exogenous or endogenous factors determine HCC mortality. With this knowledge we hope to better characterize how spontaneous regression occurs, and how we can use this information to help in developing treatment options in the future.

Fibroblast growth factor (FGF)-21 based therapies: A magic bullet for nonalcoholic fatty liver disease (NAFLD)?

Introduction: Fibroblast growth factor (FGF) 21 is a member of the FGF19 sub-family of signaling molecules. They have been found to act at the localized paracrine/autocrine and systemic endocrine levels because of their extracellular matrix and co-receptor protein binding characteristics. While the molecule circulates systemically, it has specificity conferred by a co-factor binding protein ß-Klotho which is preferentially expressed in hepatic and adipose tissues. This protein, in conjunction with the FGF receptor (FGFR), propagates the downstream effects of the growth factor signaling cascade, which has been linked to fat and glucose metabolism. FGF21 has been recognized as a possible pathway for the treatment of nonalcoholic fatty liver disease (NAFLD). Targeting of the FGF21/FGFR/ß-Klotho pathway may halt or reverse hepatic fat infiltration, inflammation, and fibrosis.Areas covered: This article summarizes preclinical and clinical data on the efficacy and safety of two FGF21 agonist therapies in development.Expert opinion: Preclinical and clinical data justify further investigation of FGF21 agonist therapies for the treatment of NAFLD. However, issues including injection site reactions and possible effects on bone homeostasis mean that safety must be evaluated carefully.

Hepatocellular carcinoma surveillance in the 21st century: Saving lives or causing harm?

Hepatocellular carcinoma (HCC) is the third most common cause of cancer related death worldwide. Prognosis and treatment options largely depend on tumor stage at diagnosis, with curative treatments only available if detected at an early stage. However, two thirds of patients with HCC are diagnosed at a late stage and not eligible for cure. Therefore several liver professional societies recommend HCC surveillance using abdominal ultrasound with or without alpha fetoprotein in at-risk populations, including patients with cirrhosis and subsets of those with chronic hepatitis B. Available data suggest HCC surveillance can significantly improve early tumor detection, curative treatment eligibility, and overall survival. However, the potential benefits of HCC surveillance must be considered in light a shifting HCC demographic from a viral-mediated cancer to an increasing proportion of patients having non-alcoholic steatohepatitis, which has been shown to limit ultrasound sensitivity and may mitigate observed benefits. Further, benefits of HCC surveillance must be weighed against potential physical, financial and psychological harms. Continued data for both benefits and harms of HCC surveillance in contemporary populations are necessary. In the interim, providers should continue to strive for high quality HCC surveillance in at-risk patients.

A review of the utility of tacrolimus in the management of adults with autoimmune hepatitis.

BACKGROUND: There is paucity of data on alternative drug therapies for patients with autoimmune hepatitis (AIH). Tacrolimus (TAC) is a promising salvage agent. We present a review of TAC therapy in AIH patients. METHODS: A search for studies with keywords 'autoimmune hepatitis' and 'tacrolimus' was performed. Reviews, studies of AIH post-transplant and AIH in children were excluded. Diagnosis of AIH was based on criteria established by the International Autoimmune Hepatitis Group. Complete biochemical response was defined as normalisation of aspartate aminotransferase (AST <45) and alanine aminotransferase (ALT <50). No biochemical response was defined as failure to return to normalisation at the end of follow-up. Demographic information and details of pre- and post-treatment liver biopsy were collected. RESULTS: Seven articles achieved the inclusion criteria and reported data for a total of 162 adult patients. The majority of studies reported average ages approximately 35 years old. Treatment duration ranged from 1 to 136 months. Indications for therapy were mostly AIH refractory to steroid treatment or inability to tolerate standard steroid treatment. Eighty-three patients (51.2%) were reported to have pre-therapy liver biopsy. Of 49 patients for whom stage was reported, 6 patients were stage 1, 16 were stage 2, 14 were stage 3 and 13 were stage 4. Of 40 patients for whom grade was reported, 1 patient was grade 0, 3 were grade 1, 9 were grade 2, 14 were grade 3 and 13 were grade 4. Dosing regimens were between 1 and 8 mg/day. Target trough TAC serum concentrations ranged from 0.5 to 10.7 ng/mL TAC was discontinued in 28 (17.3%) patients for various reasons. Renal function remained stable in most patients. One hundred and twenty-one patients (74.7%) demonstrated complete biochemical response to treatment. Post-therapy liver biopsy was obtained for 30 (18.5%) patients, and 25 (15.4%) of these patients were noted to have histological remission according to the grade of inflammation or stage of fibrosis. CONCLUSION: TAC is relatively effective in the treatment of AIH refractory to traditional therapy. It appears that liver function can be enhanced at a minimal cost to renal function. Key Points There is a cohort of patients with autoimmune hepatitis (AIH) who do not respond to standard therapy. Alternative treatment options for these patients have been explored, but outcomes have not been comprehensively examined. We report the use and efficacy of tacrolimus (TAC) in patients with AIH. We found that TAC can be safely and effectively used in patients with AIH with minimal side effects. TAC can be a potential treatment option for patients with AIH refractory to standard therapy.

Biopsy Specimens From Allograft Liver Contain Histologic Features of Hepatitis C Virus Infection After Virus Eradication.

BACKGROUND & AIMS: Most patients, even those who have received a liver transplant, achieve a sustained virologic response (SVR) to therapy for hepatitis C virus (HCV) infection. Little is known about the histologic features of liver biopsy specimens collected after SVR, particularly in patients who have received a liver transplant. We aimed to better characterize the histologic features of allograft liver biopsy specimens from patients who achieved SVR to anti-HCV therapy after liver transplantation. METHODS: We performed a retrospective analysis of 170 allograft liver biopsy specimens from 36 patients who received a liver transplant for chronic HCV infection, had recurrent HCV infection after transplantation, and subsequently achieved SVR (collected from 1999 through 2015 at 4 medical centers). SVR was defined as an undetectable serum HCV RNA level 24 weeks after completion of HCV treatment. A total of 65 biopsy specimens were post-SVR (at least 1 post-SVR from each patient; some biopsy specimens were collected at later time points from a subset of patients). We performed polymerase chain reaction analysis for HCV RNA on a subset of the biopsy specimens (28 collected before SVR and 32 after SVR). RESULTS: Of the 65 post-SVR biopsy specimens, 45 (69%) had histologic features of active HCV infection. Of the initial post-SVR biopsy specimens collected from each of the 36 patients, 32 (89%) showed these changes. For patients with more than 1 post-SVR biopsy specimen, 6 (46%) had no change in fibrosis between biopsies, and fibrosis worsened for 3 patients (23%) based on their most recent biopsy. The HCV RNA level was undetectable in 31 of the 32 biopsy specimens analyzed by polymerase chain reaction. CONCLUSIONS: In a retrospective analysis of allograft liver biopsy specimens from patients who achieved SVR after a liver transplant for chronic HCV infection, histologic changes associated with active HCV were present in 69% and fibrosis continued to progress in 23%, despite the lack of detection of HCV RNA. Pathologists should be aware of patients' SVR status when analyzing liver biopsy specimens to avoid diagnoses of chronic HCV-associated hepatitis. Because of the persistent inflammatory activity and fibrosis after SVR, clinicians should continue to monitor patients carefully after SVR to anti-HCV therapy.

Transjugular Intrahepatic Porto-Systemic Shunt in Patients with Liver Cirrhosis and Model for End-Stage Liver Disease ≥15.

BACKGROUND: It is not known whether transjugular intrahepatic porto-systemic shunt (TIPS) is safe in patients with advanced liver cirrhosis. The aim of our study was to evaluate the impact of TIPS on transplant-free survival in patients with liver cirrhosis and MELD score ≥15. METHODS: All adult patients who underwent TIPS at our institution between 2004 and 2011 were identified (N = 470). A total of 144 patients had MELD ≥15 at the time of TIPS. These patients were matched 1:1 to patients with liver cirrhosis who did not undergo TIPS based on age and MELD score using the greedy algorithm. Patients were followed up until time of death or liver transplantation. Kaplan-Meier curves and log-rank tests were used to test for differences in survival outcome between the two groups. RESULTS: A total of 288 patients with liver cirrhosis were included, of whom 144 underwent TIPS and 144 did not. The two groups were matched based on age and MELD score and were comparable with regard to gender and ethnicity. Mean MELD and Child-Pugh scores in the study population were 20.9 ± 6.5 and 10.5 ± 1.8, respectively. The most common indication for TIPS was varices (49 %), followed by refractory ascites (42 %). In the first 2 months post-TIPS, there was increased mortality or liver transplantation in patients who had TIPS compared to those who did not, but this did not reach statistical significance (p = 0.07). However, after 2 months, TIPS is associated with 56 % lower risk of dying or needing liver transplantation (p < 0.01) than cirrhotic patients who did not undergo TIPS. CONCLUSION: In patients with liver cirrhosis and MELD ≥15, TIPS might improve transplant-free survival for patients who live for at least 2 months after the procedure.

Sofosbuvir/Ledipasvir Without Ribavirin Achieved High Sustained Virologic Response for Hepatitis C Recurrence After Liver Transplantation: Two-Center Experience.

BACKGROUND: Current recommended regimens to treat patients with hepatitis C virus (HCV) infection after liver transplantation include the use of ribavirin (RBV). Limited data are available on the efficacy of RBV-free regimens posttransplant, particularly the use of sofosbuvir (SOF)/ledipasvir (LDV) without RBV in this patient population. We aimed to assess the efficacy and safety of SOF/LDV fixed-dose combination without RBV in patients with HCV recurrence posttransplant. METHODS: This is a retrospective study of 46 patients with HCV recurrence posttransplant. SOF/LDV without RBV was used for 12 weeks in patients with early-stage fibrosis (F0-F2) or for 24 weeks in those with advanced fibrosis (F3-F4) and/or cholestatic hepatitis. The primary endpoint was sustained virologic response at 12 weeks after the end of treatment. Secondary outcomes included relapse after treatment and adverse events. RESULTS: Forty-six patients, with a mean age of 62 ± 8 years, a median duration since time of transplant of 904 days (range, 78-3525 days), an HCV genotype 1, and a mean baseline viral load of 7.79 million IU/mL, were treated. Of these, 32 patients were treated for 12 weeks, and 14 patients were treated for 24 weeks. Twenty-five patients (54%) were treatment experienced (21 with interferon and 4 with SOF). All 46 patients (100%) achieved sustained virological response (SVR) 12. Neither virologic relapses nor serious adverse events were noted. CONCLUSIONS: The combination of SOF/LDV without RBV for 12 or 24 weeks produced 100% SVR 12 in patients with HCV recurrence after liver transplantation. The use of RBV may not be necessary to achieve SVR in this patient population.

Ohio solid organ transplantation consortium criteria for liver transplantation in patients with alcoholic liver disease.

AIM: To evaluate risk of recidivism on a case-by-case basis. METHODS: From our center's liver transplant program, we selected patients with alcoholic liver disease who were listed for transplant based on Ohio Solid Organ Transplantation Consortium (OSOTC) exception criteria. They were considered to have either a low or medium risk of recidivism, and had at least one or three or more months of abstinence, respectively. They were matched based on gender, age, and Model for End-Stage Liver Disease (MELD) score to controls with alcohol-induced cirrhosis from Organ Procurement and Transplant Network data. RESULTS: Thirty six patients with alcoholic liver disease were approved for listing based on OSOTC exception criteria and were matched to 72 controls. Nineteen patients (53%) with a median [Inter-quartile range (IQR)] MELD score of 24 (13) received transplant and were followed for a median of 3.4 years. They were matched to 38 controls with a median (IQR) MELD score of 25 (9). At one and five years, cumulative survival rates (± standard error) were 90% ± 7% and 92% ± 5% and 73% ± 12% and 77% ± 8% in patients and controls, respectively (Log-rank test, P = 0.837). Four (21%) patients resumed drinking by last follow-up visit. CONCLUSION: Compared to traditional criteria for assessment of risk of recidivism, a careful selection process with more flexibility to evaluate eligibility on a case-by-case basis can lead to similar survival rates after transplantation.

A guide to managing acute liver failure.

Nearly 2,000 cases of acute liver failure occur each year in the United States. This disease carries a high mortality rate, and early recognition and transfer to a tertiary medical care center with transplant facilities is critical. This article reviews the definition, epidemiology, etiology, and management of acute liver failure.

Metabolomics studies identify novel diagnostic and prognostic indicators in patients with alcoholic hepatitis.

AIM: To identify plasma analytes using metabolomics that correlate with the diagnosis and severity of liver disease in patients with alcoholic hepatitis (AH). METHODS: We prospectively recruited patients with cirrhosis from AH (n = 23) and those with cirrhosis with acute decompensation (AD) from etiologies other than alcohol (n = 25). We used mass spectrometry to identify 29 metabolic compounds in plasma samples from fasted subjects. A receiver operating characteristics analysis was performed to assess the utility of biomarkers in distinguishing acute AH from alcoholic cirrhosis. Logistic regression analysis was performed to build a predictive model for AH based on clinical characteristics. A survival analysis was used to construct Kaplan Meier curves evaluating transplant-free survival. RESULTS: A comparison of model for end-stage liver disease (MELD)-adjusted metabolomics levels between cirrhosis patients who had AD or AH showed that patients with AH had significantly higher levels of betaine, and lower creatinine, phenylalanine, homocitrulline, citrulline, tyrosine, octenoyl-carnitine, and symmetric dimethylarginine. When considering combined levels, betaine and citrulline were highly accurate predictors for differentiation between AH and AD (area under receiver operating characteristics curve = 0.84). The plasma levels of carnitine [0.54 (0.18, 0.91); P = 0.005], homocitrulline [0.66 (0.34, 0.99); P < 0.001] and pentanoyl-carnitine [0.53 (0.16, 0.90); P = 0.007] correlated with MELD scores in patients diagnosed with AH. Increased levels of many biomarkers (carnitine P = 0.005, butyrobetaine P = 0.32, homocitrulline P = 0.002, leucine P = 0.027, valine P = 0.024, phenylalanine P = 0.037, tyrosine P = 0.012, acetyl-carnitine P = 0.006, propionyl-carnitine P = 0.03, butyryl-carnitine P = 0.03, trimethyl-lisine P = 0.034, pentanoyl-carnitine P = 0.03, hexanoyl-carnitine P = 0.026) were associated with increased mortality in patients with AH. CONCLUSION: Metabolomics plasma analyte levels might be used to diagnose of AH or help predict patient prognoses.

Sofosbuvir and simeprevir without ribavirin effectively treat hepatitis C virus genotype 1 infection after liver transplantation in a two-center experience.

BACKGROUND: The interferon-free antiviral regimen, sofosbuvir (SOF) and simeprevir (SIM) without ribavirin has been reported to achieve high sustained virologic response (SVR) rates with few adverse effects when treating patients with hepatitis C genotype 1 (HCV GT1) infection. However, there is scarcity of safety and efficacy data in this regimen after liver transplantation (LT). AIM AND METHODS: We aim to report the safety, tolerability and efficacy of SOF + SIM to treat LT recipients with recurrent HCV GT1 in a multicenter cohort study. RESULTS: Eighty-one patients with HCV GT1 met criteria to be considered for treatment. Sixty-seven patients received SOF + SIM following LT to date: 69% male, 39% with HCV RNA >6 000 000 IU/mL, 22% advanced hepatic fibrosis (stage 3-4), 6% cholestatic recurrence. Fifty-eight percent previously failed or did not tolerate interferon-based treatments. Mean time from LT to treatment was 6.1 ± 5.2 yr. All patients had estimated GFR >30 mL/min. Tacrolimus was primary immunosuppression in 84% of patients and minimal immunosuppression dose adjustments were required during treatment. In intention-to-treat analysis, 90% achieved end-of-treatment virologic response and 88% achieved SVR. CONCLUSIONS: Sofosbuvir + SIM combination therapy without ribavirin is well tolerated and results in high virologic response rates in recurrent HCV GT1 infection after liver transplantation.

Management of immunosuppressant agents following liver transplantation: Less is more.

Immunosuppression in organ transplantation was revolutionary for its time, but technological and population changes cast new light on its use. First, metabolic syndrome (MS) is increasing as a public health issue, concomitantly increasing as an issue for post-orthotopic liver transplantation patients; yet the medications regularly used for immunosuppression contribute to dysfunctional metabolism. Current mainstay immunosuppression involves the use of calcineurin inhibitors; these are potent, but nonspecifically disrupt intracellular signaling in such a way as to exacerbate the impact of MS on the liver. Second, the impacts of acute cellular rejection and malignancy are reviewed in terms of their severity and possible interactions with immunosuppressive medications. Finally, immunosuppressive agents must be considered in terms of new developments in hepatitis C virus treatment, which undercut what used to be inevitable viral recurrence. Overall, while traditional immunosuppressive agents remain the most used, the specific side-effect profiles of all immunosuppressants must be weighed in light of the individual patient.

Sofosbuvir-based treatment is safe and effective in patients with chronic hepatitis C infection and end stage renal disease: a case series.

BACKGROUND & AIMS: Interferon and ribavirin-free regimens to treat chronic hepatitis C virus (HCV) infection in patients with end stage renal disease are not approved and represent an area of unmet clinical need. We report our experience on the safety and efficacy of sofosbuvir/simeprevir and sofosbuvir/ledipasvir therapy in patients on haemodialysis. METHODS: Patients with chronic HCV infection on haemodialysis were included in this study. Patients were started on either sofosbuvir/simeprevir or sofosbuvir/ledipasvir. Routine clinical and laboratory data were collected at baseline and during treatment. The primary outcome was sustained virological response at week 12 (SVR12). RESULTS: Eight patients with mean age 56.8 ± 20 years were included in this study. Seven were treatment naïve and one was a priori null responder to interferon-based therapy. Four patients were started on sofosbuvir/simeprevir and four on sofosbuvir/ledipasvir for 12 weeks. Therapy was well tolerated overall with nausea/vomiting, pruritus, headache and a 2 g/dl drop in haemoglobin developing in one patient each. No patient discontinued therapy because of side effects. Comparison of labs at baseline and nadir levels during treatment revealed no significant change in haemoglobin (10.8 ± 2.4 g/dl vs 10.3 ± 1.6 g/dl), platelet count (198 ± 164 k/µl vs 184.5 ± 162/µl) and bilirubin (0.3 ± 0.4 mg/dl vs 0.25 ± 0.15 mg/dl). Eight of eight patients had undetectable HCV RNA at the end of treatment. One patient was lost to follow up and the remaining seven achieved SVR12. CONCLUSION: Full dose sofosbuvir/simeprevir or sofosbuvir/ledipasvir therapy for HCV-infected patients with end stage renal disease was well tolerated with no discontinuation owing to side effects and no significant adverse events.

Liver Transplant in Young Adults with Chronic Hepatitis C Virus: An Argument for Hepatitis C Treatment in Childhood.

OBJECTIVES: We sought to assess the characteristics of hepatitis C virus-positive young adults who received a liver transplant and to evaluate posttransplant outcomes. MATERIALS AND METHODS: United Network for Organ Sharing database was conducted from 1989 to 2012, and retrospective analysis was performed on all hepatitis C virus-positive young adult patients (aged, 8-35 y) who underwent a liver transplant in the United States. RESULTS: A total of 506 hepatitis C virus subjects were included. Average age at time of transplant was 30.1 ± 4.8 years. Median follow-up after first liver transplant was 46.1 months (13, 89.3 mo). During this time, 217 patients (42.8%) died at a mean age at the time of death of 34 ± 6.7 years including 176/ 506 (34.8%) after the first liver transplant, 34/71 (48.6%) after the second liver transplant, and 7/8 (87.5%) after the third liver transplant. The majority (65.7%) of retransplants were performed for hepatitis C virus recurrence. A mean of 1.15 liver transplants were performed per patient. Overall, 262 subjects were transplanted in the pre-Model for End-stage Liver Disease era, and 244 were transplanted post-MELD. Younger age, higher bilirubin, higher creatinine, hepatitis C carcinoma, shorter wait time, shorter cold ischemia time, nonwhite donor race, and the use of mycophenolate mofetil were significantly more common in the post-Model for End-stage Liver Disease era (all with P < .05). Importantly, 5-year patient and graft survival were not different between the pre- and post-Model for End-stage Liver Disease era. CONCLUSIONS: Liver transplant in young adults for hepatitis C virus acquired during childhood has poor outcomes that did not improve in the post-Model for End-stage Liver Disease era. These findings should prompt more aggressive evaluation and treatment for hepatitis C virus in children.

Characterization of hepatocellular carcinoma (HCC) in non-alcoholic fatty liver disease (NAFLD) patients without cirrhosis.

BACKGROUND: The incidence of hepatocellular carcinoma (HCC) has increased significantly in United States over the last few decades in parallel with the epidemic of nonalcoholic fatty liver disease (NAFLD). Limited data suggests that HCC could arise in steatotic liver without the presence of cirrhosis. The present study was conducted to characterize patients with NAFLD presenting with HCC in non-cirrhotic liver (NCL) compared to the NAFLD- HCC patients in association with cirrhotic liver (CL). METHODS: A retrospective analysis of all patients diagnosed with HCC and NAFLD diagnosis seen at our institution between 2003 and 2012 was done. The patients were characterized based on demographic and clinical variables as well as histological and tumor features. Comparisons between the NCL and CL groups were done using analysis of variance (ANOVA) or the non-parametric Kruskal-Wallis tests and Pearson's chi-square tests or Fisher's Exact tests as appropriate. P value of <0.05 was considered statistically significant. RESULTS: Thirty-six patients with NAFLD and HCC in NCL (HCC-NCL group) were identified and compared to 47 patients with NAFLD-HCC and Liver Cirrhosis (HCC-LC group). Liver fibrosis was not present in 55.9 % of patients in the HCC-NCL group (F0), stage 1 was present in 17.6 %, stage 2 in 8.8 % and stage 3 in 17.6 %. Lobular inflammation was present in 63.6 % of non-cirrhotic patients. Patients in the HCC-NCL were older (67.5 ± 12.3 vs. 62.7 ± 8.1 years), and less likely to be obese (52 % vs. 83 %) or have type 2 diabetes (38 % vs. 83 %), with p value <0.05 for all. More importantly, compared with the HCC-CL group, those in the HCC-NCL group were more likely to present with a single nodule (80.6 % vs. 52.2 %), larger nodule size (>5 cm) (77.8 % vs. 10.6 %), and receive hepatic resection as the modality of HCC treatment (66.7 % vs. 17 %); and were less likely to receive loco-regional therapy (22.3 % vs. 61.7 %) or orthotopic liver transplantation (OLT) (0 % vs. 72.3 %), with p value <0.001 for all. Furthermore, 86 % of patients without cirrhosis had HCC recurrence compared to only 14 % in patients with cirrhosis (p < 0.001). Unadjusted analysis indicates that non-cirrhotics had worse survival with mortality rate of 47 % vs. 28 % in CL group (p = 0.03); however this difference in survival between two groups was not significant after adjusting for age or OLT (p > 0.05). CONCLUSION: Patients with HCC in the absence of liver cirrhosis are more likely to present at an older age with larger tumor and have higher rates of tumor recurrence. Studies to assess the cost-effectiveness of HCC surveillance in this group should be conducted.

Liver transplantation for nonalcoholic steatohepatitis in young patients.

Nonalcoholic steatohepatitis (NASH) is the hepatic manifestation of obesity and insulin resistance. The aim of this study was to determine the frequency of NASH as an indication for liver transplantation (LT) in children and young adults and to characterize patient and graft survival. The study included all children and young adult patients (up to the age of 40 years) who underwent LT in the United States for NASH cirrhosis from the 1987 to 2012 United Network for Organ Sharing (UNOS) database. Kaplan-Meier analysis was used to assess patient and graft survival. A total of 330 patients were included, 68% were Caucasian, and the mean BMI was 33.6 ± 6.3. Age at time of LT ranged between 4 and 40 years (mean 33.9 ± 6.6 years). Fourteen subjects were <18 years of age at time of LT and 20 were between the ages of 18 and 25 years. Median follow-up after 1st LT was 45.8 months [10.7, 97.3]. During this time, 30% of subjects (n = 100) died and 11.5% (n = 38) were retransplanted including 13 for NASH recurrence. In conclusion, NASH can progress to end-stage liver disease requiring LT in childhood and early adulthood. A significant number of young patients transplanted for NASH cirrhosis required retransplantation.
