Diagnostic criteria and long-term outcomes in AIH-PBC variant syndrome under combination therapy.

Background & Aims: Autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) can co-exist in AIH-PBC, requiring combined treatment with immunosuppression and ursodeoxycholic acid (UDCA). The Paris criteria are commonly used to identify these patients; however, the optimal diagnostic criteria are unknown. We aimed to evaluate the use and clinical relevance of both Paris and Zhang criteria.

An open-label randomised-controlled trial of azathioprine vs. mycophenolate mofetil for the induction of remission in treatment-naive autoimmune hepatitis.

Background & Aims: Patients with autoimmune hepatitis (AIH) almost invariably require lifelong immunosuppressive treatment. There is genuine concern about the efficacy and tolerability of the current standard combination therapy of prednisolone and azathioprine. Mycophenolate mofetil (MMF) has emerged as an alternative option.

Incidence and predictors of hepatocellular carcinoma in patients with autoimmune hepatitis.

Background And Aims: Autoimmune hepatitis (AIH) is a rare chronic liver disease of unknown aetiology; the risk of hepatocellular carcinoma (HCC) remains unclear and risk factors are not well-defined. We aimed to investigate the risk of HCC across a multicentre AIH cohort and to identify predictive factors.

Methods: We performed a retrospective, observational, multicentric study of patients included in the International Autoimmune Hepatitis Group Retrospective Registry.

Lack of complete biochemical response in autoimmune hepatitis leads to adverse outcome: First report of the IAIHG retrospective registry.

Background And Aims: The International Autoimmune Hepatitis Group retrospective registry (IAIHG-RR) is a web-based platform with subjects enrolled with a clinical diagnosis of autoimmune hepatitis (AIH). As prognostic factor studies with enough power are scarce, this study aimed to ascertain data quality and identify prognostic factors in the IAIHG-RR cohort.

Methods: This retrospective, observational, multicenter study included all patients with a clinical diagnosis of AIH from the IAIHG-RR.

Nomenclature, diagnosis and management of drug-induced autoimmune-like hepatitis (DI-ALH): An expert opinion meeting report.

Drug-induced liver injury (DILI) can mimic almost all other liver disorders. A phenotype increasingly ascribed to drugs is autoimmune-like hepatitis (ALH). This article summarises the major topics discussed at a joint International Conference held between the Drug-Induced Liver Injury consortium and the International Autoimmune Hepatitis Group.

Importance of complete response for outcomes of pregnancy in patients with autoimmune hepatitis.

Background And Aims: While some articles describe outcome of pregnancy in autoimmune hepatitis (AIH), there are less data evaluating influence of AIH control on maternal and perinatal outcomes. This study analysed outcomes of pregnancy and related possible risk factors in AIH.

Method: A retrospective multicentre cohort study on pregnancy in AIH was performed in 11 hospitals in the Netherlands.

Assessing the efficacy and safety of mycophenolate mofetil versus azathioprine in patients with autoimmune hepatitis (CAMARO trial): study protocol for a randomised controlled trial.

Background: Currently, the standard therapy for autoimmune hepatitis (AIH) consists of a combination of prednisolone and azathioprine. However, 15% of patients are intolerant to azathioprine which necessitates cessation of azathioprine or changes in therapy. In addition, not all patients achieve complete biochemical response (CR).

Drug withdrawal in patients with autoimmune hepatitis in long-term histological remission: A prospective observational study.

Background: Recommendations for drug withdrawal in patients with autoimmune hepatitis (AIH) in longstanding remission are conflicting and rely on retrospective data. We prospectively investigated the predictive value of histological normalisation for successful treatment withdrawal in AIH patients.

Methods: Non-cirrhotic patients with established AIH and complete biochemical remission (normalisation of serum alanine aminotransferase [ALT] or aspartate aminotransferase [AST] and immunoglobulin G [IgG]) of at least 2 years were biopsied.

Established and novel therapeutic options for autoimmune hepatitis.

Autoimmune hepatitis is an immune-mediated disorder characterised by hypergammaglobulinaemia, autoantibodies, and interface hepatitis. The mainstay of treatment is non-specific immunosuppression, consisting of steroids with or without azathioprine. Although most patients respond satisfactorily to steroid and thiopurine-based treatment regimens, up to 40% relapse and 10% undergo liver transplantation.

Adverse events related to low dose corticosteroids in autoimmune hepatitis.

Background: Autoimmune hepatitis requires long-term therapy, and systemic corticosteroids are the backbone of therapeutic management. Prolonged use of corticosteroids may lead to adverse events but data from long-term studies are mainly derived from studies in rheumatic diseases.

Aim: To assess cataract, diabetes and fractures in relation to corticosteroid doses in the long-term maintenance treatment of patients with autoimmune hepatitis.

The risk of liver cancer in autoimmune liver diseases.

Hepatocellular carcinoma (HCC), the dominant primary malignancy of the liver, has almost invariably a fatal outcome that can be averted only by early diagnosis and treatment. While the close association of HCC with chronic viral hepatitis and alcohol abuse has impacted favourably on screening and treatment of this deadly tumour, at the same time it has long obscured the etiologic role of autoimmune liver diseases. Recently, a systematic analysis of 25 published cohorts disclosed a 3.

Association Between Black Race and Presentation and Liver-Related Outcomes of Patients With Autoimmune Hepatitis.

Introduction & Aims: Small studies have found that black patients with autoimmune hepatitis (AIH) present with more aggressive disease. We aimed to characterize the presentation and outcome in black and white patients with AIH.

Methods: We performed a retrospective study, collecting information from databases of patients with AIH attending the Institute of Liver studies at King's College Hospital, London (1971-October 2015, the Royal Free Hospital, London (1982 through December 2016) and the multicenter Dutch Autoimmune Hepatitis Study Group cohort (2006-August 2016).

17-Beta Hydroxysteroid Dehydrogenase 13 Is a Hepatic Retinol Dehydrogenase Associated With Histological Features of Nonalcoholic Fatty Liver Disease.

Nonalcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease. A single-nucleotide polymorphism (SNP), rs6834314, was associated with serum liver enzymes in the general population, presumably reflecting liver fat or injury. We studied rs6834314 and its nearest gene, 17-beta hydroxysteroid dehydrogenase 13 (HSD17B13), to identify associations with histological features of NAFLD and to characterize the functional role of HSD17B13 in NAFLD pathogenesis.

Increased Mortality Among Patients With vs Without Cirrhosis and Autoimmune Hepatitis.

Background & Aims: There have been few reproducible studies of mortality in patients with autoimmune hepatitis (AIH) and its variants. We calculated mortality in a large national cohort of patients with AIH, with vs without cirrhosis, in the Netherlands.

Methods: We collected data from 449 patients with established AIH (77% female), from 6 academic and 10 non-academic hospitals in the Netherlands.

TM6SF2 Promotes Lipidation and Secretion of Hepatitis C Virus in Infected Hepatocytes.

Background & Aims: Hepatitis C virus (HCV) co-opts the very-low-density lipoprotein pathway for morphogenesis, maturation, and secretion, and circulates as lipoviroparticles (LVPs). We investigated the functions and underlying mechanisms of the lipid-associated TM6SF2 protein in modulating LVP formation and the HCV life cycle.

Methods: We knocked down or overexpressed TM6SF2 in hepatic cells and examined HCV infection, measuring viral RNA and protein levels and infectious LVP titers.

Biochemical efficacy of tioguanine in autoimmune hepatitis: a retrospective review of practice in the Netherlands.

Background: Azathioprine (AZA) and mercaptopurine (MP) are the cornerstone of steroid-sparing strategies in autoimmune hepatitis (AIH). Up to 20% of patients do not tolerate or respond to these regimens.

Aim: To evaluate retrospectively the tolerability and efficacy of tioguanine (thioguanine) (TG) therapy in selected patients with AIH and AIH variant syndromes.

Herbal and Dietary Supplement-Induced Liver Injury.

The increase in the use of herbal and dietary supplements (HDSs) over the last decades has been accompanied by an increase in the reports of HDS-associated hepatotoxicity. The spectrum of HDS-induced liver injury is diverse and the outcome may vary from transient liver test increases to fulminant hepatic failure resulting in death or requiring liver transplant. There are no validated standardized tools to establish the diagnosis, but some HDS products have a typical clinical signature that may help to identify HDS-induced liver injury.

Features of Autoimmune Hepatitis in Patients With Drug-induced Liver Injury.

Background & Aims: Drug-induced liver injury (DILI) has features similar to those of other liver diseases including autoimmune hepatitis (AIH). We aimed to characterize the clinical and autoimmune features of liver injury caused by nitrofurantoin, minocycline, methyldopa, or hydralazine.

Methods: We analyzed data from 88 cases of DILI attributed to nitrofurantoin, minocycline, methyldopa, or hydralazine included in the Drug-Induced Liver Injury Network prospective study from 2004 through 2014.

Seroprevalence of Hepatitis E Virus in Autoimmune Hepatitis Patients in the Netherlands.

Background And Aims: In recent years chronic courses of hepatitis E virus (HEV) infection have been described in immunosuppressed individuals. This may implicate a potential role for HEV in the development of autoimmune diseases, including autoimmune hepatitis (AIH). Here we investigated the prevalence of HEV-antibodies in AIH patients in an endemic Central European country.

Assessment of the histopathological key features in autoimmune hepatitis.

Aims: In this study, we aimed to evaluate the use of typical histological features of both the revised original (1999) and simplified (2008) criteria in the diagnosis of autoimmune hepatitis (AIH) in clinical practice.

Methods And Results: We performed a detailed histopathological evaluation of the pretreatment biopsies of 63 AIH patients, and used biopsies of 62 untreated chronic viral hepatitis patients [hepatitis B (n = 21) or hepatitis C (n = 41)] as a reference cohort. Biopsies were systematically reviewed for inflammation, fibrosis and the presence of interface hepatitis, plasma cells, rosettes and emperipolesis with a well-defined assessment method.

Seroprevalence of celiac disease in patients with autoimmune hepatitis.

Background And Aims: Prevalence data of celiac disease (CD) in patients with autoimmune hepatitis (AIH) are scarce. We investigated the relationship between AIH and CD by assessing the prevalence of IgA tissue antitransglutaminase antibodies (TGA) and antiendomysium antibodies (EMA) in a large cohort of AIH patients.

Methods: The frequency of CD was determined by TGA antibody serology in a cohort of 460 AIH patients.
