Background and Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD), in the context of autoimmune hepatitis (AIH) among liver transplantation (LT) candidates or recipients remains poorly understood. This study compares waitlist and post-LT outcomes in patients with MASLD/AIH to MASLD and AIH alone., Methods: Using the united network organ sharing database (2002-2022), we compared waitlist outcomes and post-LT survival among patients with MASLD/AIH (n = 282), AIH (n = 5812), and MASLD (n = 33 331). Competing risk, Kaplan Meier estimates and Cox proportional hazard analyses were performed., Results: MASLD/AIH group had the highest rates of encephalopathy and ascites, and highest MELD scores. MASLD/AIH patients had higher transplantation incidence (adjusted subdistribution hazard ratio [aSHR] 1.64, 95% CI 1.44-1.85; p < .001) and lower waitlist removal risk (aSHR .30, 95% CI .20-.44; p < .001) compared to MASLD alone. One-year post-LT survival favoured MASLD compared to AIH (patient: 92% vs. 91%, p < .001; graft: 89% vs. 88%, p < .001) and MASLD/AIH (patient: 92% vs. 90%, p = .008; graft: 89% vs. 88%, p = .023). Recipients with MASLD/AIH showed no significant difference in survival at 10-year post-LT compared to MASLD (patient: 63% vs. 61%, p = .68; graft 60% vs. 59%, p = .83) and AIH (patient: 63% vs. 70%, p = .07; graft: 60% vs. 64%, p = .42)., Conclusions: Our study showed that MASLD/AIH patients demonstrate higher LT incidence and lower dropout rates. Long-term post-LT outcomes did not significantly differ between groups. Further prospective multicenter studies are needed to validate these findings., (© 2024 John Wiley & Sons A/S.

Post-transplantation primary central nervous system lymphoma (PT-PCNSL) is a rare neoplasm that occurs in immunocompromised patients. It can manifest months or years after transplantation, presenting with various neurological symptoms. A 64-year-old woman, who had received a liver transplant due to autoimmune hepatitis, presented with generalized weakness, headache, and confusion. Further investigation revealed multiple ring-enhancing lesions in the right frontal and temporoparietal regions on brain MRI. A brain biopsy confirmed the diagnosis of PT-PCNSL. This case underscores the importance of considering PT-PCNSL in the differential diagnosis of contrast-enhancing brain lesions in post-transplant patients. Timely recognition of PT-PCNSL is crucial for appropriate management and improved outcomes. To the best of our knowledge, this report describes the first instance of isolated CNS lymphoma in a liver transplant recipient, due to autoimmune hepatitis, successfully brought to complete remission with a rituximab-methotrexate regimen., (© 2024.

Living donor liver transplantation (LDLT) offers the opportunity to decrease waitlist time and mortality for patients with autoimmune liver disease (AILD), autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis. We compared the survival of patients with a potential living donor (pLDLT) on the waitlist versus no potential living donor (pDDLT) on an intention-to-treat basis. Our retrospective cohort study investigated adults with AILD listed for a liver transplant in our program between 2000 and 2021. The pLDLT group comprised recipients with a potential living donor. Otherwise, they were included in the pDDLT group. Intention-to-treat survival was assessed from the time of listing. Of the 533 patients included, 244 (43.8%) had a potential living donor. Waitlist dropout was higher for the pDDLT groups among all AILDs (pDDLT 85 [29.4%] vs. pLDLT 9 [3.7%], p < 0.001). The 1-, 3-, and 5-year intention-to-treat survival rates were higher for pLDLT versus pDDLT among all AILDs (95.7% vs. 78.1%, 89.0% vs. 70.1%, and 87.1% vs. 65.5%, p < 0.001). After adjusting for covariates, pLDLT was associated with a 38% reduction in the risk of death among the AILD cohort (HR: 0.62, 95% CI: 0.42-0.93 [ p <0.05]), and 60% among the primary sclerosing cholangitis cohort (HR: 0.40, 95% CI: 0.22-0.74 [ p <0.05]). There were no differences in the 1-, 3-, and 5-year post-transplant survival between LDLT and DDLT (AILD: 95.6% vs. 92.1%, 89.9% vs. 89.4%, and 89.1% vs. 87.1%, p =0.41). This was consistent after adjusting for covariates (HR: 0.97, 95% CI: 0.56-1.68 [ p >0.9]). Our study suggests that having a potential living donor could decrease the risk of death in patients with primary sclerosing cholangitis on the waitlist. Importantly, the post-transplant outcomes in this population are similar between the LDLT and DDLT groups., (Copyright © 2024 American Association for the Study of Liver Diseases.)

Introduction and Objectives: Autoimmune liver diseases (AILDs): autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC) have different survival outcomes after liver transplant (LT). Outcomes are influenced by factors including disease burden, medical comorbidities, and socioeconomic variables., Materials and Methods: Using the United Network for Organ Sharing database (UNOS), we identified 13,702 patients with AILDs listed for LT between 2002 and 2021. Outcomes of interest were waitlist removal, post-LT patient survival, and post- LT graft survival. A stepwise multivariate analysis was performed adjusting for transplant recipient gender, race, diabetes mellitus, model for end-stage liver disease (MELD) score, and additional social determinants including the presence of education, reliance on public insurance, working for income, and U.S. citizenship status., Results: Lack of college education and having public insurance increased the risk of waitlist removal (HR, 1.13; 95 % CI, 1.05-1.23, and HR, 1.09; 95 % CI, 1.00-1.18; respectively), and negatively influenced post-LT patient survival (HR, 1.16; 95 % CI, 1.06-1.26, and HR, 1.15; 95 % CI, 1.06-1.25; respectively) and graft survival (HR, 1.13; 95 % CI, 1.05-1.23, and HR, 1.15; 95 % CI, 1.06-1.25; respectively). Not working for income proved to have the greatest detrimental impact on both patient survival (HR, 1.41; 95 % CI, 1.24-1.6) and graft survival (HR, 1.21; 95 % CI, 1.09-1.35)., Conclusions: Our study highlights that lack of college education and public insurance have a detrimental impact on waitlist mortality, patient survival, and graft survival. Not working for income negatively affects post-LT survival outcomes. Not having U.S. citizenship does not affect survival outcomes in AILDs patients., Competing Interests: Conflicts of interest AB sits on the science advisory board of Intercept and is a primary investigator for trials for Zydus Therapeutics Inc., ChemomAb Ltd., CymaBay Therapeutics Inc., Mirum Pharmaceuticals Inc., Intercept Pharmaceuticals, Gilead Sciences, and CARA; he receives royalties or holds licenses from UptoDate and DynaMed; he works with the AASLD Editorial Board for Clinical Liver Disease; and he has given expert testimony for Expert Review, Inc.

Autoimmune hepatitis (AIH) may recur after liver transplantation (LT). The aims of this study were to evaluate the incidence and risk factors for recurrent autoimmune hepatitis (rAIH). A multicenter retrospective French nationwide study, including all patients aged ≥16 transplanted for AIH, with at least 1 liver biopsy 1 year after LT, was conducted between 1985 and 2018. Risk factors for rAIH were identified using a multivariate Cox regression model. Three hundred and forty-four patients were included (78.8% women) with a median age at LT of 43.6 years. Seventy-six patients (22.1%) developed recurrence in a median time of 53.6 months (IQR, 14.1-93.2). Actuarial risk for developing rAIH was 41.3% 20 years after LT. In multivariate analysis, the strongest risk factor for rAIH was cytomegalovirus D+/R- mismatch status (HR=2.0; 95% CI: 1.1-3.6; p =0.03), followed by associated autoimmune condition. Twenty-one patients (27.6% of rAIH patients) developed liver graft cirrhosis after rAIH. Independent risk factors for these severe forms of rAIH were young age at LT, IgG levels >20.7 g/L, and LT in the context of (sub)fulminant hepatitis. Immunosuppression, especially long-term maintenance of corticosteroid therapy, was not significantly associated with rAIH. Recurrence of AIH after LT is frequent and may lead to graft loss. Recurrence is more frequent in young patients with active disease at the time of LT, yet systematic corticosteroid therapy does not prevent it., (Copyright © 2023 American Association for the Study of Liver Diseases.)

Objectives: Autoimmune hepatitis is a rare indication for liver transplant in Western countries. Our goal was to identify characteristics and long-term outcomes of patients who underwent liver transplant for autoimmune hepatitis-related end-stage liver disease at our center., Materials and Methods: Adult patients who underwent primary liver transplant from January 2007 to March 2022 at Imam Khomeini Hospital Complex, Tehran University of Medical Sciences, Tehran, Iran, were enrolled in our study., Results: Among 1107 patients enrolled in our study, mean age was 45.94 ± 12.43 years (range, 16-73 years) and 423 (38.2%) female patients were included. Autoimmune hepatitis was the underlying cause of cirrhosis in 177 patients (experimental group); the other 930 patients did not have autoimmune hepatitis (control group). All patients were followed for a median of 60 ± 40.3 months (range, 3-187 months) after transplant. In the experimental group, patient survival rates at 1 month, 1 year, and 3 years were 87%, 81%, and 78%, which were not significantly different between the 2 groups (P = .445). Recurrence of autoimmune hepatitis was detected in 8 patients (4.5%) in the experimental group. Acute allograft rejection was more significantly detected in the patients with recurrence of autoimmune hepatitis than in patients without recurrence of autoimmune hepatitis., Conclusions: Liver transplant in patients with autoimmune hepatitis is safe and is associated with good outcomes.

Background: Patients with autoimmune hepatitis (AIH) may co-present with features of primary biliary cholangitis (PBC) or primary sclerosing cholangitis (PSC). Using a national transplant registry, the outcomes of patients with these autoimmune liver conditions were compared., Methods: The UNOS-STAR registry was used to select a study population of AIH, PSC, and PBC liver transplant (LT) patients. Living and multi-organ transplant cases were excluded. Using the UNOS-registered diagnoses, the study population was subdivided into those with nonoverlapping autoimmune liver diseases and those with overlapping forms (e.g., AIH-PBC). Outcomes were compared, using endpoints such as all-cause mortality, graft failure, and organ-system specific causes of death., Results: The main analysis featured 2048 entries, with 1927 entries having nonoverlapping AIH, 52 entries having PSC overlap, and 69 entries having PBC overlap. Patients with PBC overlap were more likely to have graft failure (adjusted hazard ratio [aHR] 3.46 95% CI 1.70-7.05), mortality secondary to respiratory causes (aHR 3.57 95% CI 1.23-10.43), and mortality secondary to recurrent disease (aHR 9.53 95% CI 1.85-49.09). Case incidence rates reflected these findings, expressed in events per 1000 person-years. For patients with PBC overlap and nonoverlapping AIH cases, respectively. Graft failure: 28.87 events vs. 9.42 events, mortality secondary to respiratory causes: 12.83 deaths vs. 3.77 deaths, mortality secondary to recurrent disease: 6.42 deaths vs. 1.26 deaths. Those with AIH-PSC overlap experienced a higher risk of death from graft infection (aHR 10.43 95% CI 1.08-100.37; case-incidence rate: 3.89 vs. 0.31 mortalities per 1000 person-years). Supplementary analysis showed similar findings, in which overlapping autoimmune conditions were associated with higher adverse outcome rates., Conclusion: Patients with AIH-PBC overlap have higher risk of mortality due to recurrent liver disease and respiratory causes, and patients with AIH-PSC overlap have higher risk of mortality due to graft infection. While further prospective studies are needed to clarify the underlying mechanisms related to these findings, our study characterizes the prognostic implications of AIH overlap on post-LT mortality and graft failure risks., (© 2022.

Autoimmune hepatitis is a common cause of acute liver failure. Treatment includes steroids for acute liver injury and liver transplantation in those who fail to respond or develop acute liver failure. The aim of this study is to further characterize acute liver failure secondary to autoimmune hepatitis and identify variables that predict 21-day transplant-free survival. This study included adults hospitalized with acute liver failure enrolled in the Acute Liver Failure Study Group Registry between 1998 and 2019 from 32 centers within the US. The etiology of all cases was reviewed by the Adjudication Committee, and all cases identified as autoimmune hepatitis were included. Acute liver injury was defined as an INR ≥2.0 without encephalopathy and acute liver failure as INR ≥ 1.5 with encephalopathy. Laboratory and clinical data were reviewed. Variables significantly associated with 21-day transplant-free survival were used to develop a multivariable logistic regression model.  A total of 193 cases of acute liver failure secondary to autoimmune hepatitis were identified and reviewed. There were 161 patients (83.4%) diagnosed with acute liver failure on enrollment, and 32 (16.6%) developed acute liver failure during hospitalization. At 21 days, 115 (59.6%) underwent liver transplantation, 28 (14.5%) had transplant-free survival, and 46 (23.8%) died before liver transplantation. Higher admission values of bilirubin, INR, and coma grade were associated with worse outcomes. A prognostic index incorporating bilirubin, INR, coma grade, and platelet count had a concordance statistic of 0.84. Acute liver failure secondary to autoimmune hepatitis is associated with a high short-term mortality. We developed a model specifically for autoimmune hepatitis that may be helpful in predicting 21-day transplant-free survival and early identification of patients in need of expedited liver transplant evaluation., (Copyright © 2023 American Association for the Study of Liver Diseases.)

Background and Aims: Autoimmune hepatitis (AIH) is a rare indication (<5%) for liver transplantation (LT). The aim of this study was to describe the early outcome after LT for AIH., Methods: A multicenter retrospective nationwide study including all patients aged ≥16 transplanted for AIH in France was conducted. Occurrences of biliary and vascular complications, rejection, sepsis, retransplantation and death were collected during the first year after LT., Results: A total of 344 patients (78.8% of women, 17.0% of (sub)fulminant hepatitis and 19.2% of chronic liver diseases transplanted in the context of acute-on-chronic liver failure [ACLF]) were included, with a median age at LT of 43.6 years. Acute rejection, sepsis, biliary and vascular complications occurred in respectively 23.5%, 44.2%, 25.3% and 17.4% of patients during the first year after LT. One-year graft and patient survivals were 84.3% and 88.0% respectively. The main cause of early death was sepsis. Pre-LT immunosuppression was not associated with an increased risk for early infections or surgical complications. Significant risk factors for septic events were LT in the context of (sub)fulminant hepatitis or ACLF, acute kidney injury at the time of LT (AKI) and occurrence of biliary complications after LT. AKI was the only independent factor associated with graft (HR = 2.5; 95% CI: 1.1-5.4; p = .02) and patient survivals (HR = 2.6; 95% CI: 1.0-6.5; p = .04)., Conclusion: Early prognosis is good after LT for AIH and is not impacted by pre-LT immunosuppression but by the presence of AKI at the time of LT., (© 2022 The Authors.

A 77-year-old female patient was undergoing steroid treatment for cirrhosis with autoimmune hepatitis. Periodic imaging acquisitions revealed both irregular gallbladder wall thickness and an isovascular tumor in segment one of the liver. After cholecystectomy and segmental hepatectomy, the pathological diagnosis was diffuse large B-cell lymphoma in both organs. Accordingly, she received chemotherapy but the disease rapidly spread;she died five months after surgery. Malignant lymphoma of the gallbladder is an uncommon disease;we consider that autoimmunity factors were associated with this pathogenesis.

Autoimmune hepatitis (AIH) is a chronic immune-mediated inflammatory liver disease. It is known that AIH originates not from the spleen but from the liver itself. Nonetheless, most details of the etiology and pathophysiology are unknown. We induced experimental murine AIH (emAIH) in NOD/Ltj mice by single administration of a replication-deficient adenovirus and performed splenectomy during late-stage disease. Biochemical disease remission occurred, which was characterized by improvement in transaminase levels. The causes of this remission included a shift in the transcriptomic signature of serum proteins toward regeneration. At the cellular level, there was a marked decrease in activated CD8 + T cells and an increase in intrahepatic regulatory T cells (Tregs). Here, intrahepatic Treg numbers correlated with biochemical remission. Notably, an imbalance in the T-cell/B-cell ratio was observed, with a disproportionate increase in total B cells. In summary, intrahepatic increases in Tregs, biochemical remission, and regeneration could be induced by splenectomy in the late stage of emAIH., (© 2022. The Author(s).)

Liver transplantation (LT) has emerged as the best therapeutic modality for end-stage liver disease in pediatric autoimmune liver disease (AILD). We aimed to describe our experience of pediatric living donor liver transplantation for AILD from India over a period of 10 years. We did a retrospective analysis of 244 liver transplants at our center over the last 10 years to identify children with AILD (18 years or younger). We aimed to describe the demographic features, clinical profile, graft survival, patient outcome, and predictors of mortality in our cohort. Between July 2010 and May 2020, 13 liver transplants were performed for AILD out of total 244 children transplanted over the last 10 years at our center. Mean (standard deviation [SD]) age at LT was 12 (± 3.84) years. Leading indications for LT were decompensated liver disease (61.5%), acute-on-chronic liver failure (23.1%), acute liver failure (ALF) (7.7%), and recurrent cholangitis and growth failure (7.7%). Mean Pediatric End-stage Liver Disease (PELD) score/model for end-stage liver disease (MELD) score and international normalized ratio (INR) (SD) at presentation were 24 (± 12.81) and 2.48 (± 1.54), respectively. Median discharge duration was 23 days (interquartile range [IQR] 21-36 days). 30.7% (4/13) of the subjects had no postoperative complications. Diarrhea (15.3%), pneumonia (7.7%), jejunostomy site bleed (7.7%), tacrolimus toxicity (7.7%), and vascular complications (7.7%) were seen, which resolved with satisfactory graft function. Three subjects died post-LT; causes of death included sepsis (n=3), renal dysfunction (n=1), and pneumonia (n=1). Others have been well on follow-up with no graft rejection or need for re-transplantation. Overall, 1-year and 5-year patient survival rates were 76.9% and 70%, respectively. Lower platelet count, autoimmune hepatitis (AIH) 2, and PELD/MELD score were found to be significant predictors of mortality on univariate analysis, which were not significant on multivariate modelling. The complications, graft and patient survival rates in our experience were quite encouraging, and are comparable with the best centers worldwide. After instituting appropriate treatment, early referral of such patients to an equipped center should be facilitated., (© 2022. Indian Society of Gastroenterology.)

Although there have been a few liver transplantations (LTs) between identical twins, to our knowledge hepatic damage after LT in an immunosuppressant-free patient has not been reported. Autoimmune liver disease recurrence after LT is also a postoperative problem. In this follow-up to our previous report, we present the case of a 57-year-old man with acute liver failure who underwent living donor liver transplantation (LDLT) from an identical twin. Six months after LDLT, the patient was free from immunosuppressive medication and showed good liver function. However, 1 year after LDLT, he developed liver damage and was diagnosed with autoimmune hepatitis by liver biopsy. His liver function was improved with steroid pulse therapy and the resumption of immunosuppressive medications. Even after LDLT from an identical twin, careful management is required for patients to remain free of immunosuppressive medications, considering the background liver disease., (Copyright © 2022.

Introduction and Objectives: Autoimmune liver diseases such as autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis are the primary indication for ∼24% of total liver transplants. The liver transplant allocation system is currently based upon the Model for End-Stage Liver Disease and it often underestimates the severity of autoimmune liver diseases. We aim to compare the rate of adverse waitlist removal among patients with all autoimmune liver diseases and other indications for liver transplant in the Model for End-Stage Liver -Na era., Materials and Methods: Using the United Network for Organ Sharing database, we identified all patients listed for liver transplant from 2016 to 2019. The outcome of interest was waitlist survival defined as the composite outcome of death or removal for clinical deterioration. Competing risk analysis was used to evaluate the waitlist survival., Results: Patients with autoimmune hepatitis had a higher risk of being removed from the waitlist for death or clinical deterioration (SHR 1.37, 95% CI 1.08-1.72; P&lt;0.007), followed by primary biliary cholangitis (SHR 1.34, 95% CI 1.07-1.68; P&lt;0.011)., Conclusions: High waitlist death or removal for clinical deterioration was observed in patients with PBC and AIH when compared to other etiologies. It may be useful to reassess the process of awarding MELD exception points to mitigate such disparity., Competing Interests: Conflicts of interest Alan Bonder has the following disclosures: Scientific Advisory Boards: Intercept, Primary Investigator for trials for Gilead and CARA; Royalties or Licenses: UptoDate, Dynamed; Work with AASLD Editorial Board for Clinical Liver Disease; Expert testimony for Expert Review Inc., (Copyright © 2022 Fundación Clínica Médica Sur, A.C.

Background: To our knowledge, no analysis of data from liver transplantation registries exists in Canada. We aimed to describe temporal trends in the number of liver transplantation procedures, patient characteristics and posttransplantation outcomes for autoimmune liver diseases (AILDs) in Canada., Methods: We used administrative data from the Canadian Organ Replacement Register, which contains liver transplantation information from 6 centres in Canada. This study included transplantation information from 5 of the centres, as liver transplantation procedures in children were not included. We included adult (age ≥ 18 yr) patients with a diagnosis of primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC), autoimmune hepatitis (AIH) or overlap syndrome (PBC-AIH or PSC-AIH) who received a liver transplant from 2000 to 2018., Results: Of 5722 primary liver transplantation procedures performed over the study period, 1070 (18.7%) were for an AILD: 489 (45.7%) for PSC, 341 (31.9%) for PBC, 220 (20.6%) for AIH and 20 (1.9%) for overlap syndrome. There was a significant increase in the absolute number of procedures for PSC, with a yearly increase of 0.6 (95% confidence interval 0.1 to 1.2), whereas the absolute number of procedures for PBC and AIH remained stable. The proportion of transplantation procedures decreased for PBC and AIH but remained stable for PSC. Recipient age at transplantation increased over time for males with PBC (median 53 yr in 2000-2005 to 57 yr in 2012-2018, p = 0.03); whereas the median age among patients with AIH decreased, from 53 years in 2000-2005 to 44 years in 2006-2011 ( p = 0.03). The Model for Endstage Liver Disease score at the time of transplantation increased over time for all AILDs, particularly AIH (median 16 in 2000-2005 v. 24 in 2012-2018, p < 0.001). There was a trend toward improved survival in the PBC group, with a 5-year survival rate of 81% in 2000-2005 and 90% in 2012-2018 ( p = 0.06)., Conclusion: Between 2000 and 2018, the absolute number of liver transplantation procedures in Canada increased for PSC but remained stable for PBC and AIH; proportionally, PBC and AIH decreased as indications for transplantation. Posttransplantation survival improved only for the PBC group. An improved understanding of trends and outcomes on a national scale among patients with AILD undergoing liver transplantation can identify disparities and areas for potential health care improvement., Competing Interests: Competing interests: None declared., (© 2022 CMA Impact Inc. or its licensors.)

Although liver transplant is a life-saving measure for individuals with end-stage liver disease, the perioperative management may be challenging in individuals with concomitant sickle cell disease. We report a case of a 50-year-old man with sickle cell disease genotype SC (HbSC) and cirrhosis secondary to autoimmune hepatitis who underwent liver transplant. His postoperative course included upper extremity deep vein thrombosis, pulmonary embolus, stroke via a patent foramen ovale after a line removal, and posterior reversible encephalopathy syndrome. Fortunately, he is alive with a functioning graft at 10 months after liver transplant. This case highlights the feasibility of liver transplant in sickle cell disease given the support of meticulous multidisciplinary care and the unique aspects of autoimmune hepatitis and sickle cell disease for liver transplant consideration.

Background: During the current SARS-CoV-2 pandemic it is important to identify risk factors for COVID-19. Registry studies are providing growing evidence on the elevated risk of mortality from COVID-19 in patients with chronic liver disease, especially in advanced stages. Results may, however, have a selection bias towards severe cases. Limited data is available on COVID-19 in patients with autoimmune liver disease (AILD)., Aim: To perform an online survey to capture the prevalence of COVID-19 and the state of medical care of patients with AILD in Europe during the pandemic., Methods: Data was collected via an anonymous patient-oriented, online survey, which was available on the EUSurvey platform in nine European languages between 24 th June 2020 and 14 th October 2020. Of 1834 contributions, 51 were excluded because participants did not name an underlying AILD, and four were excluded because of duplicate data entry., Results: Of 1,779 participants, 1,752 resided in 20 different countries of the European Union and the United Kingdom (UK). The five countries with the highest numbers of contributions were France (n = 450), Germany (n = 318), the Netherlands (n = 267), Spain (n = 225), and the UK (n = 183). 2.2% of participants (39/1779) had been diagnosed with COVID-19. There were no differences regarding age, sex, AILD, the status of liver cirrhosis, or status post liver transplantation between COVID-19 and non-COVID-19 cases. Of the 39 COVID-19 cases, five patients were admitted to a regular ward, one patient was admitted to ICU and required ventilation., Conclusion: In our Europe-wide, patient-oriented survey on COVID-19 in patients with AILD, we detected a low rate of COVID-19, comparable to the period prevalence of the general population. These results suggest that patients with AILD are not at elevated risk of COVID-19., (© 2021 The Authors.

Background: Autoimmune hepatitis (AIH) is a rare indication for liver transplantation (LT). Data on the long-term outcomes of living-related LT for AIH are limited and inconsistent. The present study aimed to assess the long-term outcomes of deceased donor LT (DDLT) and living donor LT (LDLT) for AIH., Methods: All patients who received transplants for AIH-related cirrhosis from 2001 to 2018 were included in this study., Results: Seventy-four patients (31 male, 43 female) received LT. The average follow-up was 7.9 ± 6.9 years (median = 7.2 years), average age was 34.3 ± 13.8 years, and average Model for End-Stage Liver Disease (MELD) score was 23.6 ± 8.5. Thirty-six (49.3%) patients received a graft from a living donor, and 83% of patients were maintained on steroids. The 1-, 3-, 5-, and 10-year survival rates of patients were 91%, 89%, 87%, and 82% and of grafts were 89%, 88%, 86%, and 76%, respectively. In univariate analysis, MELD score (odds ratio [OR], 1.08; 95% confidence interval [CI], 1.01-1.17; P = .028), donor age (OR per 5 years, 1.45; 95% CI, 1.07-2.02; P = .021), donor type (OR LDLT vs DDLT, 0.19; 95% CI, 0.04-0.67; P = .017), and renal function (OR glomerular filtration rate <60 vs ≥60 mL/min/m 2 , 7.41; 95% CI, 1.88-31.25; P = .004) were significant predictors of graft survival; however, none of the factors remained significant in multivariate analysis., Conclusion: We have shown the highest reported long-term survival rates in LT for AIH, including a large number of patients who underwent LDLT. Standardized management and immunosuppressive therapy, including the maintenance of a low-dose steroid protocol, may have contributed to this outcome., (Copyright © 2021 Elsevier Inc.

Background & Aims: In acute severe autoimmune hepatitis (AS-AIH), the optimal timing for liver transplantation (LT) remains controversial. The objectives of this study were to determine early predictive factors for a non-response to corticosteroids and to propose a score to identify patients in whom LT is urgently indicated., Methods: This was a retrospective, multicenter study (2009-2016). A diagnosis of AS-AIH was based on: i) Definite or probable AIH based on the simplified IAIHG score; ii) international normalized ratio (INR) ≥1.5 and/or bilirubin >200 μmol/L; iii) No previous history of AIH; iv) Histologically proven AIH. A treatment response was defined as LT-free survival at 90 days. The evolution of variables from corticosteroid initiation (day-D0) to D3 was estimated from: Δ%3 = (D3-D0)/D0., Results: A total of 128 patients were included, with a median age of 52 (39-62) years; 72% were female. Overall survival reached 88%. One hundred and fifteen (90%) patients received corticosteroids, with a LT-free survival rate of 66% at 90 days. Under multivariate analysis, D0-INR (odds ratio [OR] 6.85; 95% CI 2.23-21.06; p <0.001), Δ%3-INR ≥0.1% (OR 6.97; 95% CI 1.59-30.46; p <0.01) and Δ%3-bilirubin ≥-8% (OR 5.14; 95% CI 1.09-24.28; p <0.04) were predictive of a non-response. The SURFASA score: -6.80+1.92∗(D0-INR)+1.94∗(Δ%3-INR)+1.64∗(Δ%3-bilirubin), created by combining these variables, was highly predictive of LT or death (AUC = 0.93) (88% specificity; 84% sensitivity) with a cut-off point of <-0.9. Below this cut-off, the chance of responding was 75%. With a score higher than 1.75, the risk of dying or being transplanted was between 85% and 100%., Conclusion: In patients with AS-AIH, INR at the introduction of corticosteroids and the evolution of INR and bilirubin are predictive of LT or death. Within 3 days of initiating corticosteroids, the SURFASA score can identify non-responders who require a referral for LT. This score needs to be validated in a prospective cohort., Lay Summary: The management of patients with acute severe autoimmune hepatitis is highly challenging, particularly regarding their early referral for liver transplantation. We found that international normalized ratio at the initiation of corticosteroid therapy and the evolution of international normalized ratio and bilirubin values after 3 days of therapy were highly predictive of liver transplantation or death. We are thus proposing a score that combines these variables and identifies patients in whom liver transplantation is urgently required., Competing Interests: Conflict of interest EDM: nothing to disclose, AC: nothing to disclose, OC: nothing to disclose, OR: nothing to disclose, JMP: nothing to disclose, PHD: nothing to disclose, FA: nothing to disclose, CS: nothing to disclose, IOH: nothing to disclose, CD: nothing to disclose, AHB: nothing to disclose, SB: nothing to disclose, NG: nothing to disclose, GPP: nothing to disclose, CB: nothing to disclose, MB: nothing to disclose, HF: nothing to disclose, VdL: nothing to disclose, JD: nothing to disclose, FC: nothing to disclose, SR: nothing to disclose, MDG: nothing to disclose, OG: nothing to disclose, FD: nothing to disclose, PP: nothing to disclose, VDM: nothing to disclose, NR: nothing to disclose, PI: nothing to disclose, MS: nothing to disclose, PM: nothing to disclose, HA: nothing to disclose, DS: nothing to disclose, JCDV: nothing to disclose.

Background: Autoimmune hepatitis (AIH) and primary sclerosing cholangitis (PSC) are rare indications for liver transplantation (LT) in children. The aim of the present retrospective multicenter study was to evaluate long-term outcome after LT for autoimmune liver disease in childhood., Methods: Retrospective data from 30 children who underwent a first LT from 1988 to 2018 were collected., Results: The study population consisted of 18 girls and 12 boys, transplanted for AIH type 1 (n=14), AIH type 2 (n=7) or PSC (n=9). Mean age at LT was 11.8±5.2 years. The main indications for LT were acute (36.7%) or chronic end-stage liver failure (63.3%). Graft rejection occurred in 19 patients (63.3%); 6 pts required retransplantation for chronic rejection. Recurrence of initial disease was observed in 6 patients (20.0%), all of them with type 1 AIH, after a median time of 42 months, requiring retransplantation in 2 cases. Overall patient survival rates were 96.4%, 84.6%, 74.8%, 68.0%, 68.0%, 68.0% and 68.0% at 1, 5, 10, 15, 20, 25 and 30 years, respectively. Age at LT<1year (p<0.0001), LT for fulminant failure (p=0.023) and LT for type 2 AIH (p=0.049) were significant predictive factors of death., Conclusion: Long-term outcome after LT for pediatric autoimmune liver disease is impaired in patients with AIH because of consistent complications such as rejection and disease recurrence., (Copyright © 2020 Elsevier Masson SAS.

Rationale: We present the case of a patient with autoimmune hepatitis who suffered fatal intracardiac and pulmonary arterial thromboembolic complications after ABO-incompatible living donor liver transplantation (ABOi LDLT) with splenectomy., Patient Concerns: A 46-year-old female (blood type B+) with autoimmune hepatitis and hepatitis B carrier status underwent elective ABOi LDLT. The donor liver was from a 51-year-old male living donor (blood type A+). A splenectomy was performed without bleeding complications. Intraoperatively, the patients hemodynamic condition was acceptable, with no evidence of thromboembolism on transesophageal echocardiography (TEE)., Diagnosis: Postoperatively, her platelet count increased from 15.0 to 263.0 (× 109/L) and thromboelastographic parameters indicated hypercoagulable state. She suffered acute circulatory collapse, respiratory distress and, eventually, a decline in mental status. The attending physicians in the intensive care unit (ICU) immediately performed resuscitation., Interventions: The patient underwent emergency exploratory surgery. Intraoperatively, hypotension, bradycardia and arrhythmia developed, together with high central venous pressure. Assessment of cardiac structure and function using rescue TEE incidentally identified multiple, huge thromboembolic clots in the cardiac chambers; therefore, the patient underwent cardiac thromboembolectomy, including cardiopulmonary bypass with hypothermia therapy., Outcomes: Due to severe cardiac and respiratory distress, the patient required venoarterial extracorporeal membrane oxygenation (VAECMO) in the operating room and ICU. Despite continuous resuscitation in the ICU and maintenance of VAECMO, she suffered severe hypotension and massive bleeding that eventually led to death., Lessons: In patients with autoimmune hepatitis, risk factors for thromboembolism should be rigorously controlled during the peak period of reactive thrombocytosis after ABOi LDLT with splenectomy., (Copyright © 2021 the Author(s).

As the current demand for liver transplantation exceeds our donor pool, the donor search is shifted towards the extended donor criteria. The livers harbouring hydatid disease are a controversial source of grafts. We report the use of a liver graft harbouring hydatid disease in urgent liver transplantation in a patient with autoimmune hepatitis. Corroborated with previous experiences, we show that the liver grafts harbouring hydatid cysts provide a rare but valuable source of organs.

Although the role of autophagy has been implicated in several forms of chronic hepatitis, it is still not fully understood. Active autophagy eliminates damaged molecules and organelles (such as mitochondria) by lysosomal degradation. In the present study, we aimed to examine and compare autophagy activity in chronic hepatitis C (CHC) and autoimmune hepatitis (AIH) by detecting the expression of autophagy (LC3 and p62) and mitochondrium-related (TOMM20) proteins, as well as the levels of selected microRNAs (miR-101, -155, -204 and - 224) known to be involved in the regulation of autophagy. In addition, the expression levels were related to pathohistological parameters. Liver biopsy samples, including 45 CHC and 18 AIH cases, were immunohistochemically stained for LC3, p62 and TOMM20 and the expression of miRNAs was determined using real-time PCR. We found elevated LC3 and p62 in AIH samples as compared with CHC ones, indicating an activated autophagy that is impaired in AIH as no degradation of p62 seemed to occur. Moreover, p62 showed strong correlation with necroinflammatory grades in the AIH group. The observed elevated levels of TOMM20 and p62 suggest a less efficient elimination of damaged mitochondria in AIH as opposed to CHC, in which autophagy seems to have a more active function. The level of miR-101 was increased in case of CHC as compared with AIH, however, miR-155, -204 and 224 resulted in no expressional. Furthermore, miR-224 level correlated with steatosis and miR-155 expression with fibrosis stage in CHC. In conclusion, dissimilar autophagic activity was observed in CHC and AIH, suggesting a close association between impaired autophagy and severity of necroinflammation. This impairment may not be regulated by the analyzed miRNAs. Nevertheless, miR-224 and - 155 seem to be associated with CHC progression.

Goals: We sought to compare posttransplant outcomes between autoimmune liver disease., Background: Autoimmune liver diseases, namely primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC), and autoimmune hepatitis (AIH) generally have favorable posttransplant outcomes. PSC is known to require more retransplantation compared with PBC, however, comparisons to AIH are lacking. We sought to compare graft survival and the need for retransplant in AIH compared with other autoimmune liver disease., Study: We compared posttransplant graft survival among the 3 entities using Cox regression and competing for risk analyses using the United Network for Organ Sharing (UNOS) database., Results: We found AIH is associated with significantly decreased graft survival compared with PBC [hazard ratio: 0.86; 95% confidence interval (CI): 0.77-0.96] and PSC (hazard ratio: 0.89; 95% CI: 0.8-0.99) after controlling for potential confounders. This is mainly driven by posttransplant death. On competing for risk analysis, AIH was associated with higher risk of death compared with PBC [subdistribution hazard ratio (SHR): 0.79; 95% CI: 0.7-0.89] and PSC (SHR: 0.72; 95% CI: 0.64-0.82) and lower risk of retransplant compared with PSC (SHR: 1.48; 95% CI: 1.19-1.8)., Conclusion: As prior studies have shown the similar risk of disease recurrence in AIH and PSC, our study indicates at least part of the increased posttransplant mortality in AIH may be due lower retransplantation rate in this population.

The aim of this study was to analyze longterm patient and graft survival after liver transplantation for autoimmune hepatitis (AIH-LT) from the prospective multicenter European Liver Transplant Registry. Patient and liver graft survival between 1998 and 2017 were analyzed. Patients after AIH-LT (n = 2515) were compared with patients receiving LT for primary biliary cholangitis (PBC-LT; n = 3733), primary sclerosing cholangitis (PSC-LT; n = 5155), and alcohol-related cirrhosis (AC-LT; n = 19,567). After AIH-LT, patient survival was 79.4%, 70.8%, and 60.3% and graft survival was 73.2%, 63.4%, and 50.9% after 5, 10, and 15 years of follow-up. Overall patient survival was similar to patients after AC-LT (P = 0.44), but worse than after PBC-LT (hazard ratio [HR], 1.48; P < 0.001) and PSC-LT (HR, 1.19; P = 0.002). AIH-LT patients were at increased risk for death (HR, 1.37-1.84; P < 0.001) and graft loss (HR, 1.35-1.80; P < 0.001) from infections compared with all other groups and had a particularly increased risk for lethal fungal infections (HR, 3.38-4.20; P ≤ 0.004). Excluding patients who died within 90 days after LT, risk of death after AIH-LT was superior compared with AC-LT (HR, 0.84; P = 0.004), worse compared with PBC-LT (HR, 1.38; P < 0.001) and similar compared with PSC-LT (P = 0.93). Autoimmune hepatitis (AIH) patients with living donor liver transplantation (LDLT) showed reduced survival compared with patients receiving donation after brain death (HR, 1.96; P < 0.001). In AIH-LT patients, overall survival is inferior to PBC-LT and PSC-LT. The high risk of death after AIH-LT is caused mainly by early fatal infections, including fungal infections. Patients with LDLT for AIH show reduced survival., (Copyright © 2020 The Authors.

Background: There are little data on the pre- and post-liver transplantation (LT) outcomes of patients having autoimmune hepatitis-primary biliary cholangitis (AIH-PBC), AIH-primary sclerosing cholangitis (AIH-PSC), and AIH-small-duct PSC (AIH-SDPSC). The aim of this study was to analyze pre- and post-LT outcomes and survival of patients having different overlap syndromes (OS) undergoing LT., Methods: Patients with compatible clinical and pathologic features of AIH-PBC (n = 86), AIH-PSC (n = 22), and AIH-SDPSC (n = 9) were included in the study. Demographic, laboratory, clinical, and survival data were analyzed. Multivariable analyses were performed to determine factors predicting transplant-free survival., Results: AIH-primary sclerosing cholangitis patients were less treatment-responsive and were more likely to undergo LT than other OS. No survival difference was noted among the 3 groups. Liver decompensation was independently associated with higher mortality (HR 21.78; 95% CI 2.50-190.01). Thirteen patients with OS underwent LT. One-year survival post-LT was 91.7%. Overall recurrence rate for OS post-LT was 8%., Conclusions: AIH-primary sclerosing cholangitis patients were more likely to require LT compared with patients having AIH-PBC. Transplant-free survival was similar among the three AIH-overlap syndromes. Allograft recurrence of OS occurred in about 10% of cases. Patients with OS appear to have good short- and medium-term post-LT outcomes in terms of graft function and overall survival., (© 2020 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Disease recurrence after organ transplantation associated with graft failure is a major clinical challenge in autoimmune diseases. Primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC) and autoimmune Hepatitis (AIH) are the three most common (autoimmune liver diseases) ALD for which liver transplantation (LT) is the most effective treatment option for patients with end-stage diseases. Although the 5- and 10-year survival rates of post-LT patients are remarkable (80-84% and 71-79% in PBC, 73-87% and 58-83% in PSC, 76-79% and 67-77% respectively in AIH patients), post-LT disease recurrence is not uncommon. Here, we summarize literature findings on disease recurrence of these ALD with emphasis on the incidence, risk factors and impact on long-term outcome. We noted that the incidence of disease recurrence varies between studies, which ranges from 53% to 10.9% in PBC, 8.2% to 44.7% in PSC and 7% to 42% in AIH. The variations are likely due to differences in study design, such as sample size, duration of studies and follow up time. This is further compounded by the lack of precise clinical diagnosis criteria and biomarkers of disease recurrence in these ALD, variation in post-LT treatment protocols to prevent disease recurrence and a multitude of risk factors associated with these ALD. While recurrence of PBC and AIH does not significantly impact long term outcome including overall survival, recurrent PSC patients often require another LT. Renal transplantation, like LT, is the treatment of choice in patients with end-stage lupus nephritis. While calcineurin inhibitor (CNI) and immunosuppressive drugs have improved the survival rate, post-transplant recurrence of lupus nephritis from surveillance-biopsy proven lupus nephritis range from 30% to 44%. On the other hand, recurrence of post-transplant lupus nephritis from registry survey analysis were only 1.1% to 2.4%. In general, risk factors associated with an increased frequency of post-transplant recurrence of autoimmune diseases are not clearly defined. Large scale multi-center studies are needed to further define guidelines for the diagnosis and clinical management to minimize disease recurrence and improve outcomes of post-transplant patients., (Copyright © 2019 Elsevier Inc.

Autoimmune hepatitis is widely assumed by health-care professionals to be a disease that is easily controlled through the use of corticosteroids and immunosuppressants but recent studies in the UK indicate highly variable treatment regimens and often unsatisfactory treatment outcomes, such as dependence on long-term high-dose steroids and ongoing need for liver transplantation in some cases. The therapeutic use of the systemically acting corticosteroid prednisolone results in unacceptable side effects in many patients. Recent evidence suggests that it is not always necessary to use high-dose steroids (>0.5 mg/kg/d) to attain remission; and side effects may also be minimised through more targeted therapy with the less systemically-absorbed corticosteroid, budesonide. The authors offer advice on the stratification of treatment for these patients and suggest changes to improve the services available for people with autoimmune hepatitis in the UK.

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease caused by JC virus reactivation. Its occurrence is very rare after solid organ transplantation, especially liver transplantation. We report a patient who received liver transplantation due to liver failure resulting from autoimmune hepatitis and advanced PML presenting with aphasia. A 41-year-old female with a history of liver transplantation who received a usual immunosuppression regimen was admitted with a stroke attack resulting in right hemiplegia 2 months after liver transplantation. Surprisingly, she gradually developed dysarthria and left central facial paresis. A brain MRI showed an abnormal multifocal area with a high T2/flair signal in the deep subcortical white matter of the left hemisphere as well as the splenium of the corpus callosum. PCR evaluation of CSF for JCV was positive while other PCR results were negative. A liver transplant recipient receiving immunosuppressive treatment for a long time could develop PML due to JCV reactivation. Only eight cases of JCV infection were reported after liver transplantation by the time of reporting this case. Unfortunately, there is no definite treatment for PML.

Background: Cytomegalovirus (CMV) remains a critical complication after solid-organ transplantation. The CMV antigenemia (AG) test is useful for monitoring CMV infection. Although the AG-positivity rate in CMV gastroenteritis is known to be low at onset, almost all cases become positive during the disease course. We treated a patient with transverse colon perforation due to AG-negative CMV gastroenteritis, following a living donor liver transplantation (LDLT)., Case Summary: The patient was a 52-year-old woman with decompensated liver cirrhosis as a result of autoimmune hepatitis who underwent a blood-type compatible LDLT with her second son as the donor. On day 20 after surgery, upper and lower gastrointestinal endoscopy (GE) revealed multiple gastric ulcers and transverse colon ulcers. The biopsy tissue immunostaining confirmed a diagnosis of CMV gastroenteritis. On day 28 after surgery, an abdominal computed tomography revealed transverse colon perforation, and simple lavage and drainage were performed along with an urgent ileostomy. Although the repeated remission and aggravation of CMV gastroenteritis and acute cellular rejection made the control of immunosuppression difficult, the upper GE eventually revealed an improvement in the gastric ulcers, and the biopsy samples were negative for CMV. The CMV-AG test remained negative, therefore, we had to evaluate the status of the CMV infection on the basis of the clinical symptoms and GE., Conclusion: This case report suggests a monitoring method that could be useful for AG-negative CMV gastroenteritis after a solid-organ transplantation., Competing Interests: Conflict-of-interest statement: The authors declare that they have no conflicts of interest.

Pediatric intractable autoimmune hepatitis is rare and may be responsible for acute liver failure. Mutations in the itchy E3 ubiquitin protein ligase ( ITCH ) gene (located on chromosome 20q11.22) can lead to a deficiency of the encoded protein, resulting in increased T-cell activity with lack of immune tolerance and manifestation of a complex systemic autoimmune disease. A 1-year-old girl of consanguineous parents received a liver transplant (LT) because of acute liver failure attributed to a drug-induced hypereosinophilic syndrome with positive liver-kidney-mikrosome-2 antibodies. Notable findings were syndromic features, dystrophy, short stature, psychomotor retardation, and muscular hypotonia. Later, we saw corticosteroid-sensitive rejections as well as a systemic autoimmune disease with detection of specific antibodies (de novo autoimmune hepatitis, thyroiditis with exophthalmos, diabetes mellitus type 1, and immune neutropenia). Histologically, liver cirrhosis with lobular inflammatory infiltrates, giant-cell hepatitis, and ductopenia was verified in chronic cholestasis. Shortly after a second LT, a comparable liver histology could be detected, and viral, bacterial, and mycotic infections deteriorated the general health condition. Because of refractory pancytopenia related to portal hypertension and hypersplenism, a posttransplant lymphoproliferative disorder was excluded. One year after the second LT, epidural and subdural bleeding occurred. Three months afterward, the girl died of sepsis. Postmortem, whole-exome sequencing revealed a homozygous mutation in the ITCH gene. A biallelic mutation in ITCH can cause a severe syndromic multisystem autoimmune disease with the above phenotypic characteristics and acute liver failure because of autoimmune hepatitis. This case reveals the importance of ubiquitin pathways for regulation of the immune system., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2019 by the American Academy of Pediatrics.)

Clinical indications for liver transplantation (LT) in patients with autoimmune hepatitis (AIH) are identical to those of patients with other chronic liver diseases that end in acute or semiacute liver failure, decompensated cirrhosis, or hepatocellular carcinoma. Recurrent disease after LT has been reported in 10%-50% of patients with AIH, and the frequency of detection is influenced in part by the use of protocol or clinically indicated liver biopsy. De novo AIH connotes the development of AIH in patients transplanted for liver diseases other than AIH, and it has been reported in 5%-10% of pediatric and 1%-2% of adult recipients. Recurrent disease can negatively impact on graft and patient survival, and retransplantation has been required in 8%-23%. De novo AIH is within the spectrum of graft dysfunction that includes plasma cell-rich rejection, and it can also progress to cirrhosis and graft failure. Treatment for recurrent or de novo disease is based on the conventional regimens for AIH, and corticosteroid therapy alone or combined with azathioprine is standard. Better control of disease activity prior to LT has been associated with less recurrence, and maintenance corticosteroid treatment after LT can reduce its frequency. In conclusion, recurrent AIH is far more frequent than de novo AIH. Both may have negative impacts on graft and patient survival, and early detection and treatment are key objectives. Future investigations must codify the diagnostic criteria for each graft dysfunction, seek diagnostic biomarkers, and evaluate treatments that improve outcomes without increasing the risk of pre- and post-LT infections., (Copyright © 2018 by the American Association for the Study of Liver Diseases.)

Background: Patients with nonalcoholic steatohepatitis (NASH) cirrhosis have excellent postliver transplant survival despite having many comorbidities. We hypothesized that this could be due to a selection bias., Methods: We analyzed the United Network for Organ Sharing data from 2002 to 2016 and compared postliver transplant survival of NASH (n = 7935) patients with cryptogenic cirrhosis (CC) (n = 6087), alcoholic cirrhosis (AC) (n = 16 810), and autoimmune hepatitis cirrhosis (AIH) (n = 2734)., Results: By 3 years of listing, the cumulative incidence (CI) of death or deterioration was 29% for NASH, 28% for CC and AC, and 24% for AIH, but when adjusted for risk factors, the CI was similar for NASH and AIH. The factors that increased the risk of waiting list removal due to death/deterioration were poor performance status, encephalopathy, diabetes, high Model for End-stage Liver Disease, Hispanic race, older age and a low serum albumin. Most patients were transplanted within the first year (median, 2 months; interquartile range, 1-7 months) of listing and by 5 years, the unadjusted CI of transplantation was 54% for NASH, 52% for CC, 51% for AIH, and 48% for AC. The adjusted CI of transplantation within 2 months of listing was higher for AC (subhazard ratio [SHR], 1.17), AIH (SHR, 1.17), and CC (SHR, 1.13) when compared with NASH, but after 2 months, adjusted transplantation rates decreased in AC (SHR, 0.6), AIH (SHR, 0.78), and CC (SHR, 0.95). The negative predictors of receiving a transplant were dialysis, female sex, nonwhite race, high albumin, and creatinine., Conclusions: Patients with NASH cirrhosis are not disadvantaged by higher waitlist removal or lower transplantation rates.

Incidental intrahepatic cholangiocarcinoma (iCCA) is a rare neoplastic lesion in the explant liver specimens with an approximate incidence of 0.7%. The detection of iCCA is associated with poor prognosis in the posttransplant setting. The occurrence of a subcentimetric iCCA is very rare and poses a major diagnostic challenge to the pathologist. This article presents a rare case of subcentimetric iCCA in a young male in the background of advanced stage chronic liver disease resulting from autoimmune hepatitis possibly with chronic cholangiopathy along with the histomorphological differentials.

Human leukocyte antigen (HLA) serotyping is not considered to have significant impact on liver graft survival and does not factor into U.S. organ allocation. Immune-related liver diseases such as primary sclerosing cholangitis (PSC), autoimmune hepatitis (AIH), and primary biliary cholangitis (PBC) have been speculated to represent a disease subgroup that may have significantly different graft outcomes depending on HLA donor/recipient characterization. The aim of this study was to investigate whether HLA serotyping/matching influenced post-transplant graft failure for immune-related liver diseases using the United Network for Organ Sharing database. From 1994 to 2015, 5665 patients underwent first-time liver-only transplants for PSC, AIH, and PBC with complete graft survival and donor/recipient HLA data. Graft failure was noted in 38.6% (2188/5665), and all groups had comparable 5-year graft survival (75.1%-78.8%, P = 0.069). The overall degree of, and loci-specific mismatch level, did not influence outcomes. Multivariable Cox proportional hazards regression noted increased graft failure risk for recipient HLA-B7, HLA-B57, HLA-B75, HLA-DR13 and donor HLA-B55, HLA-B58, and HLA-DR8 for PSC patients, protective effects for recipient HLA-DR1 and HLA-DR3 for AIH patients, and increased risk for HLA-DR7 for AIH patients. These findings warrant further investigation to evaluate the impact of HLA serotyping on post-transplant outcomes., (© 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Corticosteroids have been a mainstay of immunosuppression following liver transplantation. However, evolution in the field of transplant immunology has produced steroid-free options, resulting in most transplant centers weaning steroids after transplant within days to months-an evidence-based management decision. Patients with autoimmune hepatitis (AIH), however, receive corticosteroids prior to transplant. This raises the question of whether these patients should also be weaned from corticosteroids. In this review, we discuss the benefits of avoiding steroid use in this population of patients-an approach that not only avoids the adverse effects of corticosteroids but does so without risking graft failure from recurrent AIH or from acute cellular rejection., (© 2018 The Authors. Liver Transplantation published by Wiley Periodicals, Inc. on behalf of American Association for the Study of Liver Diseases.)

Autoimmune liver diseases (AILDs) can recur following liver transplantation (LT) despite immunosuppressive therapy, with implications for graft survival. Although the evidence is not robust, disease recurrence seems to occur in the presence of less intense and/or steroid-free immunosuppression (IS) in particular in the case of autoimmune hepatitis (AIH). The main risk factor for AIH recurrence is the severity of disease activity in the explant and potential donor/recipient human leukocyte antigen D-related 3 (DR3) mismatch. The treatment for AIH recurrence includes reintroduction or increase in the dose of steroids with or without the addition of azathioprine. T cell-mediated rejection episodes are also more common in AILD. Steroid withdrawal is the common practice in LT for non-AILD, eliminating the risks associated with longterm exposure to steroids. In AILD, maintenance of steroids at a low dose in the long term may reduce the risk of disease recurrence and rejection. This strategy is safe when there is vigilance for steroid-related adverse effects. Alternatively, identifying patients who are at the greatest risk for disease recurrence and who would benefit from intensified IS might be an option., (© 2018 The Authors.

Objectives: Autoimmune liver disease (AILD) incorporates primary sclerosing cholangitis (PSC), autoimmune hepatitis (AIH), and autoimmune sclerosing cholangitis (ASC). ASC is a condition that includes overlap of AIH and PSC. We investigate changes in practice in relation to diagnosis and phenotype over 2 time periods., Methods: Retrospective chart review was conducted from January 2000 to 2016. Data were divided into two 8-year cohorts, CI and C2., Results: Data were collected in 75 children, 29 in 2000-2007 (C1) and 46 in 2008-2016 (C2). Presenting AILD type was AIH in 59%, ASC in 10%, and PSC in 31%. Final AILD type was AIH in 53%, ASC in 16%, and PSC in 31%. When comparing C1 to C2, those with AIH decreased (65% vs 45%) and those with ASC increased (14% vs 18%). Use of magnetic resonance cholangio-pancreatography increased from 34% in C1 to 65% in C2. Advanced liver disease on biopsy was noted in 53% of all children at presentation. Only 5 female children progressed to liver transplant (3 ASC-IBD [inflammatory bowel disease]; 1 PSC-IBD; 1 AIH). Colonoscopy performance increased from 48% in C1 to 63% in C2 with diagnosis of AILD-IBD increasing from 31% to 52%. Right-sided disease was present in 46% and macroscopic rectal sparing in 36% of those with ulcerative colitis (UC). Colectomy was required in 3 children with large duct PSC-IBD., Conclusions: PSC and ASC are increasing in relevance along with IBD and reflect increasing performance of magnetic resonance cholangio-pancreatography and colonoscopy. Large duct PSC and ASC with IBD are risk factors for colectomy and along with female gender, for liver transplant.

Introduction: Hepatopulmonary syndrome (HPS) is a serious complication of liver disease, which is characterized by the presence of intrapulmonary vasodilation and progressive hypoxemia. Liver transplantation is the only effective treatment., Objective: To show our results of patients with hepatopulmonary syndrome undergoing liver transplantation., Materials and Methods: Retrospective, descriptive and cross-sectional study. From March 2000 to December 2016; 226 liver transplants were performed. Of the total, 25 patients were excluded: 12 retransplantation, 9 liver-kidney combined transplants, 2 transplants for acute liver failure, 2 transplants in non-cirrhotic patients. Of the 201 patients with pretransplant diagnosis of liver cirrhosis, 19 filled criteria for SHP; who were distributed according to age, sex, hypoxemia level (pO2), Child-Pugh score and MELD score. The reversibility hypoxemia after liver trasplantation was measured with a cut-off of p02 >75 mmHg., Results: The prevalence of SHP in our series was 9.45%. The average age was 41 years (14-65); the M / F ratio of 1.65. The 78.94% (15/19) were adults. 89.5% (17/19) were Score of Child-Pugh B and C, and 68.4% had severe and very severe SHP. In 94.11% of patients, reversibility SHP founded. The early mortality rate (30 days) in patients with SHP was 10.4%., Conclusions: The prevalence of HPS in our series was 9.45%. Transplanted patients with and without SHP had similar survival.

Background: The outcomes of liver transplantation (LT) in patients with cryptogenic cirrhosis (CC) have not been adequately examined except for small case series. We believe that patients currently listed as CC have truly cryptogenic liver disease and may have different post-LT outcomes compared with nonalcoholic steatohepatitis (NASH)., Methods: We compared the post-LT outcomes of adults with CC (n = 3241) and compared them with cirrhosis from NASH (n = 4089), alcoholic cirrhosis (AC) (n = 7837), and autoimmune hepatitis (AIH) (n = 1435) using the United Network for Organ Sharing database from 2002 to 2016. We excluded those who had multiorgan transplantation and hepatocellular carcinoma. In addition to the well-known predictors of liver transplant outcomes, we analyzed the impact of Karnofsky Performance Status score at LT on immediate and late outcomes., Results: There were significant differences in clinical characteristics between the groups. Despite these differences in clinical characteristics and risk factors, CC had similar graft and patient survival to NASH, AC, and AIH when assessed by Kaplan-Meier survival. Multivariate Cox regression analysis showed that graft and patient survival was similar in all 4 groups after adjusting for other confounders. Hispanics had a 24% lower risk of death (hazard ratio, 0.76) compared with whites in these combined cohorts after adjusting for all risk factors. In addition to other known risk factors, Karnofsky Performance Status score of 30% or less was associated with a 33% increase in risk of death (hazard ratio, 1.33) on multivariate analysis., Conclusion: Patients with CC had similar graft and patient survival when compared with NASH, AC, and AIH cirrhosis.

Background: Autoimmune liver diseases (ALDs) consist of autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC), IgG4-associated cholangitis and overlap syndromes. Patients with these diseases may gradually progress to end-stage liver diseases and need liver transplantation. The present study aimed to explore the prognosis of patients with ALDs after liver transplantation., Methods: The clinical data of 80 patients with ALD (24 cases of AIH, 35 of PBC, 15 of PSC and 6 of AIH-PBC overlap syndromes) who underwent liver transplantation in Renji Hospital, Shanghai Jiao Tong University School of Medicine from June 2004 to September 2016 were collected retrospectively. The causes of death were analyzed and the postoperative cumulative survival rate was estimated by the Kaplan-Meier method. Recurrence and other complications were also analyzed., Results: Of the 80 patients, 18 were males and 62 were females. The average age was 50.5 years and the average Model for End-stage Liver Disease (MELD) score was 14.1. After a median follow-up of 19.8 months, 8 patients died. The 1-, 3- and 5-year cumulative survival rates were all 89.0%. Three cases of recurrent ALDs were diagnosed (3.8%) but they were not totally consistent with primary diseases. Biliary tract complication occurred in 10 patients (12.5%). The new onset of tumor was observed in 1 patient (1.3%). De novo HBV/CMV/EBV infection was found in 3, 8 and 3 patients, respectively., Conclusion: Liver transplantation is an effective and safe treatment for end-stage ALD., (Copyright © 2018 First Affiliated Hospital, Zhejiang University School of Medicine in China.

Introduction: Autoimmune hepatitis is a chronic liver disease that impacts on morbidity and mortality of patients. Few epidemiological data exist of this in Latin America and Colombia., Objectives: The aim of this study is to describe the demographic, clinical and laboratory characteristics of the patients; the treatment and the response to it, the evolution and course of the disease, requirement of liver transplantation and mortality., Methods: Historical cohort study that include patients attended at an University Hospital in Medellin, Colombia between January 2010 and December 2016 with ≥16 years age at the time of diagnosis of autoimmune hepatitis. Data collection was done from the review of medical records. Statistical analysis was performed using SPSS version 20., Results: The study included 278 patients, 90% of the patients were women, the median age at diagnosis was 50 years. 37.8% were cirrhotic at the time of diagnosis. The biochemical remission was 85%. In patients who developed cirrhosis it was found a higher proportion of men (21.2 vs. 7.8%, p=.027), a greater frequency of overlap autoimmune-primary sclerosant cholangitis (6.0 vs. 0% p=.006) and a greater frequency of non-response to treatment (12.1 vs. 1.6%, p=.004)., Conclusion: Autoimmune hepatitis is not a rare disease in Colombian population; it predominates in women but has a less favourable course in men. An important number of patients are cirrhotic at the time of diagnosis, the response to treatment and complications in our population are similar to those described worldwide., (Copyright © 2017 Elsevier España, S.L.U.

Introduction: The recurrence of autoimmune hepatitis (HAI) following liver transplantation occurs between 8-68%. In our experience, autoimmune liver diseases are a major indication of liver transplantation., Objective: To determine the recurrence of autoimmune hepatitis in 15 years of experience and to evaluate the risk factors associated with the recurrence of HAI., Materials and Methods: Retrospective, descriptive and cross-sectional study. From March 2000 to December 2015; 200 transplants were performed on 190 liver transplants; 36 patients were diagnosed for hepatic cirrhosis by HAI and underwent liver biopsy if transaminase (TGP-TGO >2 ULN) in 2 consecutive measurements. The diagnosis was made by histological criteria., Results: The indication for hepatic transplantation for HAI was 19%. Mean age was 35 years (range 16-64 years) relationship between Sex F / M 2.2, the most common HAI subtype is type 1 (89%). The HAI histological recurrence was 31% (11/36). The mean follow-up was 54 months (range 8-169 months)., Conclusions: Autoimmune hepatitis is the most frequent indication of liver transplantation in our experience, accounting for 19%. The recurrence of post-transplant HAI was 31%. No association was found between the degree of severity of histological activity in the explants and the type of HLA in the presentation of the recurrence.

Background: Autoimmune hepatitis is a rare inflammatory disease of the liver that most frequently affects children and young adults. It is a multifactorial disease of unknown etiology, characteristically progressive in nature, and if left untreated, may lead to cirrhosis and terminal liver failure. It has been known for several decades now that immunosuppressive treatment convincingly alters the outcome of most patients with autoimmune hepatitis and as such it should be started as soon as diagnosis is made. Primary goals of treatment are: normalization of hepatocellular function, extinction of the hepatic necroinflammatory process, and maintenance of a stable remission, thus preventing progression to cirrhosis and its complications. This article aims to review old and new treatments for this rare chronic disorder, from the oldest and most frequently used treatment consisting of the association of prednisone and azathioprine, to alternative medical treatments, liver transplant and promising medical strategies currently under investigation., Result and Conclusion: The review will focus on the efficacy and safety profile of each drug, as well as on the published clinical experience with them in pediatric patients with autoimmune hepatitis., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.)
