Hepatotoxicity of Drugs Used in Multiple Sclerosis, Diagnostic Challenge, and the Role of HLA Genotype Susceptibility. Int J Mol Sci 2023; 24:ijms24010852. [PMID: 36614299 PMCID: PMC9821303 DOI: 10.3390/ijms24010852] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Revised: 12/23/2022] [Accepted: 12/27/2022] [Indexed: 01/05/2023] Open
Abstract
Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system and the association with other autoimmune diseases is well-documented. There are many therapeutic options for the treatment of MS. Most of the available drugs cause drug-induced liver injury (DILI) to variable extents with heterogeneous clinical and biological manifestations, including liver injury with or without signs of hypersensitivity and autoimmunity. The diagnosis of DILI may be particularly difficult because MS is frequently associated with idiopathic autoimmune hepatitis. Recent advances suggest that MS and immune-mediated DILI could be promoted by genetic factors, including HLA genotype. In addition, some of these drugs may promote hepatitis B virus reactivation. This review explores the potential hepatotoxicity of drugs used to treat MS and the criteria to distinguish DILI from idiopathic autoimmune hepatitis associated with MS. The role of susceptible genes both promoting MS and causing the hepatotoxicity of the drug used for MS treatment is also discussed.

Abstract
Background Immune-mediated liver injury caused by checkpoint inhibitors (ILICI) is a challenging clinical management issue. Although immunosuppressants are widely used to manage ILICI, no large-scale studies have proved definitive evidence for the most effective form of patient management. Aim Analysis of the effectiveness of immunosuppression for immune-related liver injury. Methods We performed a systematic review and meta-analysis of the clinical outcomes of immunosuppressive treatment of ILICI patients. A literature search of PubMed, Ovid, and Cochrane Library was completed for dates from 2000 to January 1, 2022. The primary outcome was the response rate to immunosuppressive therapy for ILICI, with subgroup analysis based on the type of cancer, immune checkpoint inhibitor regimen, and severity of liver injury. The secondary outcome was the median time to recovery from ILICI with immunosuppressive therapy. Results A total of 30 studies that included 1120 patients were collected. The pooled ILICI response rate was 79% (95% CI 0.73-0.84) for treatment with corticosteroids and 93% (95% CI 0.79-1.0) for treatment with mycophenolate mofetil. For ILICI treated with corticosteroids, the median recovery time was 47.59 (95% CI 39.79-55.40) days compared to 37.74 (95% CI 31.12-44.35) days for all forms of immunosuppression. Conclusion Findings support the effectiveness of corticosteroids and mycophenolate mofetil for the treatment of ILICI. The identified median time to recovery is a beneficial guide for patients and physicians, allowing for realistic expectations and appropriate treatment management. Future prospective randomized controlled trials are required to define a standardized management approach to immunosuppressive therapy of ILICI.

Abstract
BACKGROUND Data show that patients with autoimmune hepatitis have significantly reduced quality-of-life and that corticosteroids carry marked side effects. AIMS This study explored patients' experiences of autoimmune hepatitis and its treatments; key aspects for developing safe and effective new approaches to therapy. METHODS An anonymised, internet-based survey collected data including patient demographics, treatments, side-effects, impact on day-to-day life, sources of support and attitudes towards autoimmune hepatitis between December 2019-January 2020. Semi-structured interviews were conducted with 13 patients to further explore their support networks, treatment experiences and health priorities. Descriptive and quantitative analyses were undertaken using R and free text responses were subject to thematic analysis. RESULTS In total, 270 survey responses were received (median age 55 years and 94% female). Perceived medication side-effects were reported by 66% (169/257) and 73% responded negatively about their experience of corticosteroids. The majority (62·3% [(109/175]) would 'definitely' or 'probably' consider clinical trial participation to improve their care. Only 18·7% (31/166) reported access to a specialist liver nurse and nearly half were involved in support groups. Interview and survey data suggested that major issues were stigma, loss of control and fatigue. CONCLUSIONS This study provides insights into the realities of living with autoimmune hepatitis with clear issues around lack of support networks, need for patient empowerment and stigma surrounding liver disease. Patient priorities are better therapies to slow disease progression, avoiding corticosteroids and minimising side-effects. Patient willingness to participate in trials suggests that they are achievable provided they have the right design and clinical endpoints.

Abstract
BACKGROUND & AIMS Autoimmune hepatitis (AIH) is a chronic inflammatory liver condition that predominantly affects women. However, pregnancy risks remain unclear. METHODS A nationwide population-based cohort study (ESPRESSO) in Sweden from 1992 to 2016 including 309 singleton births in women with AIH and 1532 matched births in women from the general population was performed. AIH was diagnosed as a combination of administrative coding from medical diagnosis of AIH and liver biopsy data from Sweden's 28 pathology departments. Using conditional logistic regression, odds ratios (ORs) for adverse pregnancy outcomes were determined. RESULTS Among 306 live births to women with AIH, 51 (16.7%) were preterm, compared with 70 of 1524 (4.6%) reference births. This corresponded to an OR of 5.10 for preterm birth (95% confidence interval [CI], 3.29-7.92), with similar odds using sibling comparators. Women with AIH with and without cirrhosis had similar odds for preterm birth. The AIH association was particularly strong with medically indicated preterm birth (OR, 13.01; 95% CI, 5.50-30.79). AIH was associated with low birth weight (OR, 5.31; 95% CI, 2.82-9.99) and low 5-minute Apgar score (OR, 3.46; 95% CI, 1.14-10.49) offspring, but we found no association with congenital malformations (OR, 1.14; 95% CI, 0.68-1.91), small for gestational age (OR, 1.04; 95% CI, 0.38-2.85), stillbirth (OR, 0.59; 95% CI, 0.02-18.88), or neonatal death (OR, 7.42; 95% CI, 0.65-84.25). Maternal AIH was linked to an increased odds of cesarean section (OR, 1.44; 95% CI, 1.04-2.00) and preeclampsia (OR, 3.65; 95% CI, 2.01-6.64), but not to gestational diabetes. CONCLUSIONS Maternal AIH was associated with a 5-fold higher odds of preterm birth, and cirrhosis at diagnosis did not add to the impact of AIH on preterm birth. Future studies are needed to understand how to reduce this risk.

Abstract
BACKGROUND AND AIMS A considerable number of autoimmune hepatitis (AIH) patients completely or partially fail on first-line treatment. Several studies on the use of calcineurin inhibitors (CNIs) in the treatment of AIH have been published without focusing on indication. The aim was to assess the efficacy of CNIs in the treatment of adult AIH patients, specifically focusing on indication: first-line intolerant and with first-line insufficient response (failure to achieve or maintain remission), and with second versus third-line treatment. METHODS A literature search included studies on the use of CNIs in adult AIH. Patients with past or present use of CNIs from the Dutch AIH group cohort were added. The primary endpoint was biochemical remission while using CNIs. Secondary endpoints were biochemical response, treatment failure, and adverse effects. RESULTS Twenty studies from the literature and nine Dutch patients were included describing the use of cyclosporine in 59 and tacrolimus in 219 adult AIH patients. The CNI remission rate was 53% in patients with insufficient response to first-line treatment and 67% in patients intolerant to first-line treatment. CNIs were used as second-line treatment in 73% with a remission rate of 52% and as third-line treatment in 22% with a remission rate of 26%. Cyclosporine was discontinued in 13% and tacrolimus in 11% of patients because of adverse events. CONCLUSIONS CNIs as rescue treatment in adult AIH patients are reasonably effective and safe both with insufficient response or intolerance to previous treatment. Prospective studies are needed.

Abstract
Background and aims Tetraspanin proteins are closely related to the functional changes of B cells, including antigen presentation, production of cytokines, and transduction. We aim to explore the potential role of Tetraspanin 1 (TSPAN1) in the biological activities of B cells in AIH. Methods and results Herein, this study found that numbers of cells expressing TSPAN1 were significantly increased in AIH patients compared to PBC, chronic hepatitis B, and healthy control (P < 0.0001). Moreover, there was a positive correlation between numbers of TSPAN1+ cells and AIH disease severity (P < 0.0001). Immunofluorescence staining further confirmed that TSPAN1 was primarily expressed on CD19+ B cells. Flow-cytometric analysis showed that TSPAN1+ B cells secreted more inflammatory cytokines and expressed higher level of CD86 than TSPAN1- B cells. Furthermore, compared with TSAPN1- cells, the expression of CXCR3 on TSPAN1+ cells was also higher. Meanwhile, CXCL10, the ligand of CXCR3, was significantly elevated in the liver of AIH (P < 0.01) and had positive correlation with the quantities of TSPAN1 (P < 0.05). Interestingly, the numbers of TSPAN1+ B cells were decreased in AIH patients after immunosuppressive therapy. Conclusions TSPAN1+ B cells in the liver may promote the progression of AIH via secreting cytokines and presenting antigens. The chemotactic movement of TSPAN1+ B cells toward the liver of AIH was possibly due to CXCR3 - CXCL10 interaction.

Abstract
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). Uncontrolled data indicate that mycophenolate mofetil (MMF) can induce CR in a majority of patients. Better understanding of first-line treatment and robust evidence from randomised clinical trials are needed. The aim of this study was to explore the potential benefits of MMF as compared to azathioprine, both combined with prednisolone, as induction therapy in a randomised controlled trial in patients with treatment-naive AIH. METHODS CAMARO is a randomised (1:1), open-label, parallel-group, multicentre superiority trial. All patients with AIH are screened for eligibility. Seventy adult patients with AIH from fourteen centres in the Netherlands and Belgium will be randomised to receive MMF or azathioprine. Both treatment arms will start with prednisolone as induction therapy. The primary outcome is biochemical remission, defined as serum levels of alanine aminotransferase and immunoglobulin G below the upper limit of normal. Secondary outcomes include safety and tolerability of MMF and azathioprine, time to remission, changes in Model For End-Stage Liver Disease (MELD)-score, adverse events, and aspects of quality of life. The study period will last for 24 weeks. DISCUSSION The CAMARO trial investigates whether treatment with MMF and prednisolone increases the proportion of patients in remission compared with azathioprine and prednisolone as the current standard treatment strategy. In addition, we reflect on the challenges of conducting a randomized trial in rare diseases. TRIAL REGISTRATION EudraCT 2016-001038-91 . Prospectively registered on 18 April 2016.

Abstract
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.

Abstract
BACKGROUND There is an increasing number of liver injury cases resembling autoimmune hepatitis (AIH) following SARS-CoV-2 vaccination; however, an association has not yet been established. METHODS/MATERIALS A literature review was performed to identify articles regarding the association of AIH with vaccination, emphasizing on SARS-CoV-2 vaccines, and the proposed mechanisms. We then performed a literature search for AIH-like cases following SARS-CoV-2 vaccination, and we evaluated the included cases for AIH diagnosis using simplified diagnostic criteria (SDC), and for vaccination causality using the Naranjo score for adverse drug reactions. RESULTS We identified 51 AIH-like cases following SARS-CoV-2 vaccination. Forty cases (80%) were characterized as "probable", "at least probable", or "definite" for AIH diagnosis according to SDC. Forty cases (78.4%) were characterized as "probable", four (7.8%) as "possible", and three (5.8%) as "definite" for vaccine-related AIH according to the Naranjo score. CONCLUSION SARS-CoV-2 vaccine-related AIH carries several phenotypes and, although most cases resolve, immunosuppressive therapy seems to be necessary. Early diagnosis is mandatory and should be considered in any patient with acute or chronic hepatitis after SARS-CoV-2 vaccination, especially in those with pre-existing liver disease.

Abstract
BACKROUND In acute severe autoimmune hepatitis (AS-AIH), the early identification of predictors of non-response to corticosteroids and the optimal timing for liver transplantation (LT) remains controversial. AIMS To determine early predictors of non-response to corticosteroids and to assess the usefulness of severity scores, namely the recently developed SURFASA. METHODS Retrospective multicentre cohort study including consecutive patients admitted for AS-AIH between 2016 and 2020. Definitions- response to corticosteroids: LT-free survival at 90 days (D90); SURFASA score: -6.8 + 1.92x(D0-INR)+1.94xINR[(D3-D0)/D0]+1.64xbilirubin[(D3-D0)/D0]. RESULTS We included 26 patients [median age 56 (45-69) years; 22 (84.6%) women]. All patients underwent corticosteroid therapy. Overall survival reached 73%. amongst the non-responders, 2 (7.8%) underwent LT and 5 (19.2%) died. The interval between admission and initiation of corticosteroids was not different between responders and non- responders [13 (7-23) vs. 8 (3-10), P:0.06], respectively. SURFASA and MELD-Na+ (D3) scores showed an AUROC of 0.96 (0.87-1) and 0.92 (0.82-0.99), respectively, for prediction of non-response. SURFASA >-2.5 had a sensitivity of 85.7% and a specificity of 100% and MELD-Na+ (D3) >26 had sensitivity of 85.7% and a specificity of 78% for the prediction of non-response. CONCLUSIONS SURFASA and MELD-Na+ at D3 scores are useful in early identification of non-responders to corticosteroids.

Abstract
Autoimmune hepatitis (AIH) is a rare disease of unclear etiology characterized by loss of self-tolerance that can lead to liver injury, cirrhosis, and acute liver failure. First-line treatment consists of systemic corticosteroids, or budesonide, and azathioprine, to which most patients are initially responsive, although predictors of response are lacking. Relapses are very common, correlate with histological activity despite normal serum transaminases, and increase hepatic fibrosis. Furthermore, current regimens lead to adverse effects and reduced quality of life, whereas medication titration is imprecise. Biomarkers that can predict the clinical course of disease, identify patients at elevated risk for relapse, and improve monitoring and medication dosing beyond current practice would have high clinical value. Herein, we review novel candidate biomarkers in adult and pediatric AIH based on prespecified criteria, including gene expression profiles, proteins, metabolites, and immune cell phenotypes in different stages of AIH. We also discuss biomarkers relevant to AIH from other immune diseases. We conclude with proposed future directions in which biomarker implementation into clinical practice could lead to advances in personalized therapeutic management of AIH.

Abstract
Antinuclear antibodies (ANA) are a heterogeneous group of autoantibodies that react with various components of the cell nucleus and cytoplasm. ANA is the main serological marker for autoimmune liver disease (AILD). The aim of the study was to compare the diagnostic value of two methods of screening for the determination of ANA (indirect immunofluorescence reaction on HEp-2 cells (IIF -HEp-2) and enzyme-linked immunosorbent assay (ELISA) in the sera of AILD patients. The sera of 118 patients with AILD (51 with autoimmune hepatitis - AIH, 19 with primary biliary cholangitis - PBC, 48 with overlapping syndrome - OVERLAP), 30 patients with non-alcoholic fatty liver disease (NAFLD) and 30 healthy donors (HD) were studied. Determination of ANA by the IIF-HEp-2 method was carried out by visual assessment of samples under an AXIOSKOP 40 microscope, by ELISA - on an Alegria automatic analyzer. A weak degree of agreement between the positive and negative results of the ANA screening study using IIF-HEp-2 and ELISA (Cohen's kappa coefficient æ=0.4) was noted. Screening determination of ANA in patients with AILD by the IIF-HEp-2 method was distinguished by greater diagnostic sensitivity (DS) (68.6%) and a lower frequency of false negative results (31.4%) compared with ELISA (35.6% and 64.4 % respectively, p<0.05). The overall diagnostic specificity (DS) of the ANA study in IIF-HEp-2 was lower than with ELISA (66.7% and 86.7%, respectively, p<0.05). Both screening methods for determining ANA (IIF-HEp-2 and ELISA) were useful for diagnosing AILD (positive likelihood ratio - LR+: 2.1 and 2.6, respectively). In terms of the negative likelihood ratio (LR-), screening for ANA by the IIF-HEp-2 method, in contrast to ELISA, served as a "useful" test to exclude the diagnosis of AILD (0.5 and 0.8, respectively). The determination of ANA using IIF-HEp-2 is the most sensitive and "useful" screening test for the diagnosis of AILD, and ELISA is classified as a less "useful" screening method due to low diagnostic sensitivity and a high false-negative rate.

Abstract
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<0.007), followed by primary biliary cholangitis (SHR 1.34, 95% CI 1.07-1.68; P<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.

Abstract
The term 'PBC/AIH-overlap' has been applied when features of autoimmune hepatitis (AIH), be they biochemical, serological or histological, coexist with primary biliary cholangitis (PBC), either at first presentation or sequentially during disease course. Several treatment paradigms have been proposed, extrapolated from those of the primary conditions. However, there are no randomised studies showing improved survival with combination therapy compared to bile acid monotherapy. In the absence of high-quality evidence, multidisciplinary patient-specific approaches must be used to individualise treatment pathways, with appreciation that disease phenotypes are not always static, differ in treatment responses, and have the potential to evolve over time.

Abstract
Timely diagnosis and management of severe acute-onset autoimmune hepatitis (SA-AIH), a potential cause of acute liver failure (ALF), are challenging. An initial trial of corticosteroids (CS) followed by an assessment of clinical responses over 1-2 weeks is advocated by the latest international practice guidelines1,2 and expert reviews.3,4 Consideration of a second-line drug while evaluating for liver transplantation (LT) is also recommended.2 Established predictors of "CS responsiveness" to guide decision-making are nonexistent. Herein, we determined the diagnostic abilities of early dynamics to define CS responsiveness in SA-AIH using the model for end-stage liver disease (MELD) scores.

Abstract
The antibody and B cell responses after inactivated SARS-CoV-2 vaccination have not been well documented in patients with autoimmune liver disease (AILD). Therefore, we conducted a prospective observational study that included AILD patients and healthy participants as controls between July 1, 2021, and September 30, 2021, at the Second Affiliated Hospital of Chongqing Medical University. All adverse events (AEs) after the COVID-19 vaccination were recorded and graded. Immunoglobulin (Ig)-G antibodies against the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein (anti-RBD-IgG) and neutralizicadng antibodies (NAbs) were tested following full-course vaccination (BBIBP-CorV or CoronaVac). In addition, SARS-CoV-2-specific B cells were detected by flow cytometry. In total, 76 AILD patients and 136 healthy controls (HCs) were included. All AEs were mild and self-limiting, and the incidences were similar between the AILD and HCs. The seropositivity rates of anti-RBD-IgG and NAbs in AILD were 97.4% (100% in HCs, p = 0.13) and 63.2% (84.6% in HCs, p < 0.001), respectively. The titers of anti-RBD-IgG and NAbs were significantly lower in AILD patients than those in HCs. After adjusting for confounders, immunosuppressive therapy was an independent risk factor for low-level anti-RBD-IgG (adjusted odds ratio [aOR]: 4.7; 95% confidence interval [CI], 1.5-15.2; p = 0.01) and a reduced probability of NAbs seropositivity (aOR, 3.0; 95% CI, 1.0-8.9; p = 0.04) in AILD patients. However, regardless of immunosuppressants, the SARS-CoV-2-specific memory B cells responses were comparable between the AILD and HC groups. Our results suggest that inactivated SARS-CoV-2 vaccines (BBIBP-CorV and CoronaVac) are safe, but their immunogenicity is compromised in patients with AILD. Moreover, immunosuppressants are significantly associated with poor antibody responses to the SARS-CoV-2 vaccines. These results could inform physicians and policymakers about decisions on screening the populations at higher risk of poor antibody responses to SARS-CoV-2 vaccines and providing additional vaccinations in patients with AILD.

Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) have become a mainstay of cancer treatment. Their immune-boosting quality has one major drawback, their proclivity to induce a broad array of immune-related adverse events (irAEs) affecting, among others, the liver and sharing some similarities with classic autoimmune liver diseases (AILD).We aimed to compare clinical, laboratory and histological features of patients with liver-related irAEs and AILD. METHODS We systematically compared liver irAEs with AILD, namely autoimmune hepatitis (AIH) and primary biliary cholangitis, regarding their clinical, laboratory, and histological features. RESULTS Twenty-seven patients with liver irAEs (ICI group) and 14 patients with AILD were identified. We observed three distinct ICI-induced histological liver injury patterns: hepatitic (52%), cholangitic (19%), and mixed (29%). When comparing the ICI and AILD groups, centrilobular injury as well as granuloma formation were more prevalent in the former (p=0.067 and 0.002, respectively). CD4+/CD8+ T cell ratios were heterogeneous between the two groups, without statistically significant difference but with a trend toward increased CD8+ T cells among hepatitic irAEs as compared with AIH. Pattern of liver function test alteration was predictive for the type of irAEs but did not correlate with histological severity. CONCLUSIONS Liver irAEs have broad clinical, laboratory and histological presentations. Histological features of irAEs and AILD are distinct, likely underpinning their different immunological mechanisms.

Abstract
Personalized medicine (PM) aims individualized approach to prevention, diagnosis, and treatment. Precision Medicine applies the paradigm of PM by defining groups of individuals with akin characteristics. Often the two terms have been used interchangeably. The quest for PM has been advancing for centuries as traditional nosology classification defines groups of clinical conditions with relatively similar prognoses and treatment options. However, any individual is characterized by a unique set of multiple characteristics and therefore the achievement of PM implies the determination of myriad demographic, epidemiological, clinical, laboratory, and imaging parameters. The accelerated identification of numerous biological variables associated with diverse health conditions contributes to the fulfillment of one of the pre-requisites for PM. The advent of multiplex analytical platforms contributes to the determination of thousands of biological parameters using minute amounts of serum or other biological matrixes. Finally, big data analysis and machine learning contribute to the processing and integration of the multiplexed data at the individual level, allowing for the personalized definition of susceptibility, diagnosis, prognosis, prevention, and treatment. Autoantibodies are traditional biomarkers for autoimmune diseases and can contribute to PM in many aspects, including identification of individuals at risk, early diagnosis, disease sub-phenotyping, definition of prognosis, and treatment, as well as monitoring disease activity. Herein we address how autoantibodies can promote PM in autoimmune diseases using the examples of systemic lupus erythematosus, antiphospholipid syndrome, rheumatoid arthritis, Sjögren syndrome, systemic sclerosis, idiopathic inflammatory myopathies, autoimmune hepatitis, primary biliary cholangitis, and autoimmune neurologic diseases.

Abstract
Usually associated with autoimmune diseases, anti-neutrophil cytoplasmic antibodies are also detected in other conditions, such as infections, malignancies, and after intake of certain drugs. Even if the mechanisms of production and their pathogenic role have not been fully elucidated yet, ANCA are widely recognized as a clinically alarming finding due to their association with various disorders. While ANCA target several autoantigens, proteinase-3, and myeloperoxidase are the ones proved to be most frequently related to chronic inflammation and tissue damage in murine models. Albeit these autoantibodies could be present as an isolated observation without any implications, ANCA are frequently used in clinical practice to guide the diagnosis in a suspect of small vessel vasculitis. Conditions that should prompt the clinician to test ANCA status range from various forms of lung disease to renal or peripheral nervous system impairment. ANCA positivity in the presence of an autoimmune disease, especially rheumatoid arthritis, or connective tissue diseases, is frequently correlated with more clinical complications and treatment inefficacy, even in the absence of signs of vasculitis. For this reason, it has been postulated that ANCA could represent the final expression of an immune dysregulation rather than a pathogenic event responsible for organs damage. Recently, it has also been proposed that ANCA specificity (PR3 or MPO) could possibly define ANCA-associated vasculitides better than clinical phenotype. This review aims at summarizing the latest advancements in the field of ANCA study and clinical interpretation.

Abstract
BACKGROUND Autoimmune hepatitis (AIH) may coexist with metabolic syndrome-associated diseases (MSADs) given patients' inherent need for corticosteroid therapy, as well as general population trends. AIM To examine the impact of MSAD risk factors on AIH or its treatment, and vice versa METHODS: This was a multi-centre retrospective cohort study of 552 patients with AIH diagnosed between January 2000 and December 2019. Data relating to demographic factors, laboratory values, AIH medications and MSADs were collected at diagnosis and at 1- and 3-year follow-up. Statistical relationships were analysed and reported. RESULTS We included 552 patients in the study cohort (median age 50 years, 76.1% female). All MSADs, including hypertension, dyslipidaemia, diabetes and a gain of BMI ≥3 kg/m2 , increased within the AIH cohort over time. Initial treatment regimen impacted de novo diabetes but not other MSAD development. AIH biochemical remission was less frequent at 3 years post-diagnosis among patients with ≥1 MSAD. The incidence of new MSADs could be predicted by baseline factors in certain cases. CONCLUSION In the largest US-based cohort of patients newly diagnosed with AIH, there was a considerable burden of pre-existing and de novo MSADs that may affect AIH treatment outcomes. Identifying those at highest risk of co-morbid MSADs allows for an individualised approach to management to reduce its long-term sequelae in patients with AIH.

Abstract
The NLRP3 inflammasome is a multiprotein binding compound comprising NLRP3, connector protein ASC, and effector protein pro-caspase-1. When the NLRP3 inflammasome senses a danger signal from the host or pathogen, activated caspase-1 cleaves the precursors of interleukin (IL)-1β and IL-18 into mature proinflammatory cytokines, simultaneously causing lysis via the pore-forming protein gasdermin D. This induction of cell inflammatory pyroptosis suggests that it is a key process in the innate immune response to pathogens or cellular stress. Recent studies have shown that NLRP3 inflammasome also plays an important role in regulating autoimmune liver diseases, including autoimmune hepatitis, primary biliary cholangitis, and primary sclerosclerotic cholangitis. In this review, we summarize the structure, activation and modulation of the NLRP3 inflammasome, highlight the progress in research on the role of NLRP3 inflammasome in the occurrence and development of autoimmune liver diseases, and discuss potential strategies for targeting the NLRP3 inflammasome in the treatment of autoimmune liver diseases.

Abstract
Background. Assessment of liver fibrosis is essential to guide treatment in autoimmune hepatitis (AIH), but non-invasive tests (NITs) showed poor accuracy. Our study aims to evaluate the performance of NITs among different AIH presentations. Methods. Monocentric retrospective study among 122 AIH patients. NITs were compared to histological grading of liver fibrosis. We performed an accuracy analysis among acute (jaundice and/or transaminases > 10 times upper limit of normal) and non-acute patients. Results. A significant difference in the distribution of NIT values for each Ishak stage was found for spleen-diameter-to-platelet-count ratio (SD/PC) (p < 0.001), fibrosis-4-score (FIB-4) (p = 0.002), AST-to-ALT ratio (AAR) (p = 0.002), red-blood-cell-width-distribution-to-platelet-count ratio (RDW/PC) (p = 0.008) and AST-to-platelet-count ratio (APRI) (p = 0.029). The AUC for advanced fibrosis of SD/PC, FIB-4, RDW/PC, APRI and AAR were, respectively, 0.814, 0.770, 0.768, 0.708 and 0.694. The AUC of SD/PC, FIB-4 and APRI in non-acute subgroup were 0.902, 0.834 and 0.758, while in acute patients they were 0.754, 0.724 and 0.716. RDW/PC and AAR weren’t different among the two subgroups. Conclusions. For SD/PC, FIB-4 and APRI, diagnostic accuracy is higher in patients with non-acute presentation. In this context, SD/PC and FIB-4 showed an overall performance that could be of interest in clinical practice alongside other non-invasive techniques.

Abstract
BACKGROUND Autoimmune hepatitis (AIH) is a rare chronic progressive liver disease, managed with corticosteroids and immunosuppressants and monitored using a combination of liver biochemistry and histology. Liver biopsy (gold standard) is invasive, costly and has risk of complications. Non-invasive imaging using multiparametric magnetic resonance (mpMR) can detect the presence and extent of hepatic fibroinflammation in a risk-free manner. OBJECTIVE To conduct early economic modelling to assess the affordability of using mpMR as an alternative to liver biopsy. METHODS Medical test costs associated with following 100 patients over a 5-year time horizon were assessed from a National Health Service payor perspective using tariff costs and average biopsy-related adverse events costs. Sensitivity analyses modelling the cost consequences of increasing the frequency of mpMR monitoring within the fixed cost of liver biopsy were performed. RESULTS Per 100 moderate/severe AIH patients receiving an annual mpMR scan (in place of biopsy), early economic modelling showed minimum cost savings of £232 333. Per 100 mild/moderate AIH patients receiving three mpMR scans over 5 years estimated minimum cost savings were £139 400. One-way sensitivity analyses showed increasing the frequency of mpMR scans from 5 to 10 over 5 years in moderate/severe AIH patients results in a cost saving of £121 926.20. In patients with mild/moderate AIH, an increase from 3 to 6 mpMR scans over 5 years could save £73 155.72. In a minimalistic approach, the use of 5 mpMR scans was still cost saving (£5770.48) if they were to replace two biopsies over the 5-year period for all patients with moderate/severe or mild/moderate AIH. CONCLUSIONS Integration of mpMR scans in AIH patient pathways leads to significant cost savings when liver biopsy frequency is either reduced or eliminated, in addition to improved patient experience and clinician acceptability as well as providing detailed phenotyping to improve patient outcomes.

Abstract
BACKGROUND & AIMS Autoimmune hepatitis episodes have been described following SARS-CoV-2 infection and vaccination but their pathophysiology remains unclear. Herein, we report the case of a 52-year-old male, presenting with bimodal episodes of acute hepatitis, each occurring 2-3 weeks after BNT162b2 mRNA vaccination. We sought to identify the underlying immune correlates. The patient received oral budesonide, relapsed, but achieved remission under systemic steroids. METHODS Imaging mass cytometry for spatial immune profiling was performed on liver biopsy tissue. Flow cytometry was performed to dissect CD8 T-cell phenotypes and identify SARS-CoV-2-specific and EBV-specific T cells longitudinally. Vaccine-induced antibodies were determined by ELISA. Data were correlated with clinical laboratory results. RESULTS Analysis of the hepatic tissue revealed an immune infiltrate quantitatively dominated by activated cytotoxic CD8 T cells with panlobular distribution. An enrichment of CD4 T cells, B cells, plasma cells and myeloid cells was also observed compared to controls. The intrahepatic infiltrate showed enrichment for CD8 T cells with SARS-CoV-2-specificity compared to the peripheral blood. Notably, hepatitis severity correlated longitudinally with an activated cytotoxic phenotype of peripheral SARS-CoV-2-specific, but not EBV-specific, CD8+ T cells or vaccine-induced immunoglobulins. CONCLUSIONS COVID-19 vaccination can elicit a distinct T cell-dominant immune-mediated hepatitis with a unique pathomechanism associated with vaccination-induced antigen-specific tissue-resident immunity requiring systemic immunosuppression. LAY SUMMARY Liver inflammation is observed during SARS-CoV-2 infection but can also occur in some individuals after vaccination and shares some typical features with autoimmune liver disease. In this report, we show that highly activated T cells accumulate and are evenly distributed in the different areas of the liver in a patient with liver inflammation following SARS-CoV-2 vaccination. Moreover, within the population of these liver-infiltrating T cells, we observed an enrichment of T cells that are reactive to SARS-CoV-2, suggesting that these vaccine-induced cells can contribute to liver inflammation in this context.

Abstract
Patients suffering from autoimmune hepatitis, a chronic immune-mediated liver disease with an incidence of 0.9 to 2 per 100,000 population per year in Europe, are considered to have a particularly increased risk for coronavirus disease 2019 (Covid-19)-associated hospitalization and death.1,2 Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) vaccination provides an essential tool to reduce morbidity and mortality in this cohort. However, a large multicenter study in China has shown a lower immunogenic response to inactivated whole-virion SARS-CoV-2 vaccines of chronic liver disease patients in comparison with the healthy population.3 Furthermore, reports from inflammatory bowel diseases or rheumatic disorders showed a reduced serologic response in patients taking glucocorticoids or thiopurine.4,5 The decrease in vaccine-induced antibodies over time, as well as the emergence of variants of concern, led to the recommendation of an additional vaccination in immunocompromised patients.

Abstract
The case of a 28-year-old man who had primary sclerosing cholangitis and autoimmune hepatitis overlapping syndrome (PSC-AIH OS) complicated by ulcerative colitis (UC) is reported. First, he was diagnosed with PSC complicated by UC and initially treated with ursodeoxycholic acid and mesalazine. Twenty-four months later, liver damage reappeared, and we performed a liver biopsy, which showed the features of AIH. We eventually diagnosed him with PSC-AIH OS complicated by UC. If liver damage worsens in PSC patients, PSC-AIH OS should be considered. The optimum management approach for PSC-AIH OS should be established.

Abstract
A diet rich in saturated fat and carbohydrates causes low-grade chronic inflammation in several organs, including the liver, ultimately driving nonalcoholic steatohepatitis. In this setting, environment-driven lipotoxicity and glucotoxicity induce liver damage, which promotes dendritic cell activation and generates a major histocompatibility complex class II (MHC-II) immunopeptidome enriched with peptides derived from proteins involved in cellular metabolism, oxidative phosphorylation, and the stress responses. Here, we demonstrated that lipotoxicity and glucotoxicity, as driven by a high-fat and high-fructose (HFHF) diet, promoted MHC-II presentation of nested T and B cell epitopes from protein disulfide isomerase family A member 3 (PDIA3), which is involved in immunogenic cell death. Increased MHC-II presentation of PDIA3 peptides was associated with antigen-specific proliferation of hepatic CD4+ immune infiltrates and isotype switch of anti-PDIA3 antibodies from IgM to IgG3, indicative of cellular and humoral PDIA3 autoreactivity. Passive transfer of PDIA3-specific T cells or PDIA3-specific antibodies also exacerbated hepatocyte death, as determined by increased hepatic transaminases detected in the sera of mice subjected to an HFHF but not control diet. Increased humoral responses to PDIA3 were also observed in patients with chronic inflammatory liver conditions, including autoimmune hepatitis, primary biliary cholangitis, and type 2 diabetes. Together, our data indicated that metabolic insults caused by an HFHF diet elicited liver damage and promoted pathogenic immune autoreactivity driven by T and B cell PDIA3 epitopes.

Abstract
Vitamin D is a crucial nutrient with many pleiotropic effects on health and various chronic diseases. The purpose of this review is to provide a detailed report on the pathophysiological mechanisms underlying vitamin D deficiency in patients with chronic liver disease, addressing the different liver etiologies and the condition of advanced chronic liver disease (cirrhosis) with related complications. To date, patients with liver disease, regardless of underlying etiology, have been shown to have reduced levels of vitamin D. There is also evidence of the predictive role of vitamin D values in complications and progression of advanced disease. However, specific indications of vitamin D supplementation are not conclusive concerning what is already recommended in the general population. Future studies should make an effort to unify and validate the role of vitamin D supplementation in chronic liver disease.

Abstract
Aim: To investigate whether genotypes of XDH, GMPS and MOCOS were associated with azathioprine-induced adverse drug reaction (ADR) and had the gene-gene interactions with NUDT15 rs116855232 to induce leukopenia. Methods: Patients who had taken azathioprine were recruited. Genotyping of those gene was performed. Risk factor to ADR was analyzed by logistic regression. The generalized multifactor dimensionality reduction (GMDR) was assessed based on gene-gene interactions with ADR. Results: A total of 111 patients were included in this study, all of whom were Han Chinese. XDH rs2295475 was a risk factor of myelotoxicity (p = 0.022). NUDT15 rs116855232 was a risk factor of myelotoxicity, grade ≥2 leukopenia and drug treatment termination (p-values were <0.05). Rs2295475 and rs116855232 had a gene-gene interaction. The model was associated with grade ≥2 leukopenia (OR: 17.99; 95% CI: 4.11-78.81). Conclusion: Combined testing genotype for rs2295475 and rs116855232 could improve the prediction of azathioprine-induced leukopenia.

Abstract
Autoimmune hepatitis (AIH) in pregnancy has many unique considerations. Evidence provided from single center studies with patient level data and nationwide population studies provide valuable insight into this complex situation. Because a planned pregnancy is a safer pregnancy, preconception counseling is a crucial opportunity to optimize care and risk stratify women with AIH. Women with chronic liver disease who receive preconception advice and counseling are more likely to achieve stable liver disease at conception and undergo appropriate variceal surveillance. Loss of biochemical response in pregnancy is associated with adverse outcomes in unstable disease. New onset AIH in pregnancy should be managed with classical treatment regimens. The continued use of immunosuppression in pregnancy, with the exception of mycophenolate mofetil, has not shown to adversely affect the rates of stillbirth or congenital malformation. Previously adopted immunosuppression withdrawal paradigms in pregnancy should no longer be considered advantageous, because remission loss postdelivery is likely (12%-86%). Population studies, report improved outcomes with preterm birth rates falling from 20% to 9%-13% in AIH pregnancies over a 20-year period. Newer data have also demonstrated an increased risk of gestational diabetes and hypertensive complications in AIH pregnancy, which has implications for management and preeclampsia prevention with aspirin use. This review aims to provide the framework to guide and manage pregnancy in AIH outlining pearls and pitfalls to ensure optimal outcomes for mother, baby and to reduce variation in practice.

Abstract
Nitrofurantoin, minocycline, methyldopa and infliximab, have been found to induce autoimmune-like hepatitis (DI-AILH). Evidence for other drugs and herbal and dietary supplements (HDS) is unclear. The aims of the study were to establish criteria to define and review the published evidence of suspected DI-AILH. Search was undertaken in Pubmed using search terms "drug-induced liver injury," "autoimmune hepatitis," and "drug-induced autoimmune hepatitis." DI-AILH was defined as (1) drug as a potential trigger of liver injury with autoimmune features and histological findings compatible with AIH; (2) no or incomplete recovery or worsening of liver tests after discontinuation of the drug; (3) corticosteroids requirement or spontaneous recovery; (4) follow-up without immunosuppression (IS) and no relapse of AIH at least 6 months after discontinuation of IS; and (5) drugs potentially inducing AILH with a chronic course. Cases fulfilling the first four criteria were considered probable DI-AILH with three possible DI-AILH. A total of 186 case reports were identified for conventional drugs (n = 148; females 79%; latency 2.6 months) and HDS (n = 38; females 50%). The most commonly reported agents of DI-AILH were interferons (n = 37), statins (n = 24), methylprednisolone (MPS) (n = 16), adalimumab (n = 10), imatinib (n = 8), and diclofenac (n = 7). Tinospora cordifolia and Khat were the only HDS with probable DI-AILH cases. No relapses of AIH were observed when IS was stopped after interferons, imatinib, diclofenac, and methylprednisolone. Conclusion: Beyond well-recognized nitrofurantoin, methyldopa, hydralazine, minocycline, and infliximab as causes of DI-AILH, interferons, imatinib, adalimumab, and MPS were the best-documented agents leading to probable DI-AILH. Khat and Tinospora cordifolia were the only HDS found to be able to induce DI-AILH. Long-term immunosuppression appears to be rarely required in patients with DI-AILH due to these drugs.

The aim of this study was to determine the independent prognostic value of aminotransferases and immunoglobulin G (IgG) during treatment on long-term transplant-free survival in AIH. METHODS In a multicenter cohort alanine aminotransferase, aspartate aminotransferase (AST), and IgG were collected at diagnosis and 6, 12, 24, and 36 months after start of therapy and related to long-term outcome using Kaplan-Meier survival and Cox regression analysis with landmark analysis at these time points, excluding patients with follow-up ending before each landmark. RESULTS A total of 301 AIH patients with a median follow-up of 99 (range, 7-438) months were included. During follow-up, 15 patients required liver transplantation and 33 patients died. Higher AST at 12 months was associated with worse survival (hazard ratio [HR], 1.86; P < .001), while IgG was not associated with survival (HR, 1.30; P = .53). In multivariate analysis AST at 12 months (HR, 2.13; P < .001) was predictive for survival independent of age, AST at diagnosis and cirrhosis. Multivariate analysis for AST yielded similar results at 6 months (HR, 2.61; P = .001), 24 months (HR, 2.93; P = .003), and 36 months (HR, 3.03; P = .010). There was a trend toward a worse survival in patients with mildly elevated aminotransferases (1-1.5× upper limit of normal) compared with patients with normal aminotransferases (P = .097). CONCLUSIONS Low aminotransferases during treatment are associated with a better long-term survival in autoimmune hepatitis. IgG was not associated with survival in first 12 months of treatment. Normalization of aminotransferases should be the treatment goal for autoimmune hepatitis to improve long-term survival.

Abstract
Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease that mainly injures the hepatocytes. The autoimmune disease might be involved in its aetiology, but this remains to be confirmed. Recently epidemiological studies of AIH in Asia have been broadly conducted, revealing characteristics and management of AIH patients in Asia. In East Asia, most AIH patients are type 1, and type 2 AIH is very rare. However, type 2 AIH in South Asia is as frequent as in Europe and the USA. HLA-DR4 is associated with the characteristics of type 1 AIH in East Asia, whereas HLA-DR3 occurs in AIH patients from South Asia. AIH prevalence worldwide is increasing, and several studies have reported a prevalence of 19.44, 22.80 and 12.99 per 100 000 people in Europe, the USA and Asia respectively. A meta-analysis of studies on AIH showed similar annual incidence rates for all regions, with 1.31, 1.37 and 1.00 per 100 000 people in Asia, Europe and the USA respectively. The increase in the rates could be attributable to the increased awareness of disease concepts and diagnosis. In South Asia, most cases were diagnosed as AIH only after having progressed to cirrhosis, which may cause a higher mortality rate in South Asia than in East Asia. Therefore, the early diagnosis and treatment of AIH patients can improve the current situation in Asia.

Abstract
Patients with inflammatory bowel disease (IBD) often have other immune-mediated inflammatory diseases (IMIDs), and the prevalence of any IMID is higher in IBD patients than in the general population. IBD and other IMIDs involve alterations in innate and adaptive immune responses. Their co-occurrence depends on shared immune and inflammatory processes, pathogenic mechanisms, and genetic and environmental risk factors, including drugs, especially tumor necrosis factor inhibitors. The more common IMIDs associated with IBD have been widely described, so this review focuses on the less frequent associations. The IMIDs discussed here are skin disorders (psoriasis, atopic dermatitis, vitiligo, epidermolysis bullosa acquisita, cutaneous polyarteritis nodosa, and hidradenitis suppurativa), hepato-pancreatic diseases (autoimmune hepatitis, granulomatous hepatitis, and autoimmune pancreatitis), endocrine diseases (autoimmune thyroid diseases, and type 1 diabetes mellitus), multiple sclerosis, and respiratory diseases (asthma, bronchiectasis, and interstitial pneumonia). The early detection of IMIDs in IBD patients is important to prevent their deleterious clinical course and limit their psychological impact. Care for IBD patients with IMIDs should be multispecialist, with a single therapeutic strategy instead of treating each disease separately.

Abstract
Inborn errors of immunity (IEI), formerly known as primary immunodeficiency disorders (PIDs), are inherited disorders caused by damaging germline variants in single genes, which result in increased susceptibility to infections and in allergic, autoimmune, autoinflammatory, nonmalignant lymphoproliferative, and neoplastic conditions. Along with well-known warning signs of PID, attention should be paid to signs of immune dysregulation, which seem to be equally important to susceptibility to infection in defining IEI. The modern diagnostics of IEI offer a variety of approaches but with some problems. The aim of this review is to discuss the diagnostic challenges in IEI patients in the context of an immune dysregulation background.

Abstract
Background The development of liver cirrhosis is usually an asymptomatic process until late stages when complications occur. The potential reversibility of the disease is dependent on early diagnosis of liver fibrosis and timely targeted treatment. Recently, the use of non-invasive tools has been suggested for screening of liver fibrosis, especially in subjects with risk factors for chronic liver disease. Nevertheless, large population-based studies with cost-effectiveness analyses are still lacking to support the widespread use of such tools. The aim of this study is to investigate whether non-invasive liver stiffness measurement in the general population is useful to identify subjects with asymptomatic, advanced chronic liver disease. Methods This study aims to include 30,000 subjects from eight European countries. Subjects from the general population aged ≥ 40 years without known liver disease will be invited to participate in the study either through phone calls/letters or through their primary care center. In the first study visit, subjects will undergo bloodwork as well as hepatic fat quantification and liver stiffness measurement (LSM) by vibration-controlled transient elastography. If LSM is ≥ 8 kPa and/or if ALT levels are ≥1.5 x upper limit of normal, subjects will be referred to hospital for further evaluation and consideration of liver biopsy. The primary outcome is the percentage of subjects with LSM ≥ 8kPa. In addition, a health economic evaluation will be performed to assess the cost-effectiveness and budget impact of such an intervention. The project is funded by the European Commission H2020 program. Discussion This study comes at an especially important time, as the burden of chronic liver diseases is expected to increase in the coming years. There is consequently an urgent need to change our current approach, from diagnosing the disease late when the impact of interventions may be limited to diagnosing the disease earlier, when the patient is asymptomatic and free of complications, and the disease potentially reversible. Ultimately, the LiverScreen study will serve as a basis from which diagnostic pathways can be developed and adapted to the specific socio-economic and healthcare conditions in each country. Trial registration This study is registered on Clinicaltrials.gov (NCT03789825). Supplementary Information The online version contains supplementary material available at 10.1186/s12889-022-13724-6.

Abstract
Autoimmune diseases (AID) are increasingly prevalent conditions which comprise more than 100 distinct clinical entities that are responsible for a great disease burden worldwide. The early recognition of these diseases is key for preventing their complications and for tailoring proper management. In most cases, autoantibodies, regardless of their potential pathogenetic role, can be detected in the serum of patients with AID, helping clinicians in making a definitive diagnosis and allowing screening strategies for early -and sometimes pre-clinical- diagnosis. Despite their undoubted crucial role, in a minority of cases, patients with AID may not show any autoantibody, a condition that is referred to as seronegative AID. Suboptimal accuracy of the available laboratory tests, antibody absorption, immunosuppressive therapy, immunodeficiencies, antigen exhaustion, and immunosenescence are the main possible determinants of seronegative AID. Indeed, in seronegative AID, the diagnosis is more challenging and must rely on clinical features and on other available tests, often including histopathological evaluation and radiological diagnostic tests. In this review, we critically dissect, in a narrative fashion, the possible causes of seronegativity, as well as the diagnostic and management implications, in several AID including autoimmune gastritis, celiac disease, autoimmune liver disease, rheumatoid arthritis, autoimmune encephalitis, myasthenia gravis, Sjögren's syndrome, antiphospholipid syndrome, and autoimmune thyroid diseases.

Abstract
Autoimmune liver diseases like autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis, and IgG4-related cholangitis are chronic inflammatory diseases of the liver with an autoimmune background. The therapy of autoimmune hepatitis targets the autoreactive immune system and is largely dependent on the use of glucocorticoids and cytostatic drugs. In contrast, the treatment of cholestatic autoimmune liver diseases is restricted to the use of secondary or semi-synthetic bile acids, like ursodeoxycholic acid or obeticholic acid. Although the management of the disease using such drugs works well for the majority of patients, many individuals do not respond to standard therapy. In addition, chronic treatment with glucocorticoids results in well-known side effects. Further, the use of bile acids is a symptomatic therapy that has no direct immunomodulatory effect. Thus, there is still a lot of room for improvement. The use of animal models has facilitated to elucidate the pathogenesis of autoimmune liver diseases and many potential target structures for immunomodulatory therapies have been identified. In this review, we will focus on autoimmune hepatitis for which the first animal models have been established five decades ago, but still a precise treatment for autoimmune hepatitis, as obtainable for other autoimmune diseases such as rheumatoid arthritis or multiple sclerosis has yet to be introduced. Thus, the question arises if our animal models are too far from the patient reality and thus findings from the models cannot be reliably translated to the patient. Several factors might be involved in this discrepancy. There is first and foremost the genetic background and the inbred status of the animals that is different from human patients. Here the use of humanized animals, such as transgenic mice, might reduce some of the differences. However, there are other factors, such as housing conditions, nutrition, and the microbiome that might also play an important role. This review will predominantly focus on the current status of animal models for autoimmune hepatitis and the possible ways to overcome discrepancies between model and patient.
