Statins Are Associated With a Decreased Risk of Severe Liver Disease in Individuals With Noncirrhotic Chronic Liver Disease. Clin Gastroenterol Hepatol 2024; 22:749-759.e19. [PMID: 37121528 DOI: 10.1016/j.cgh.2023.04.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 02/07/2023] [Accepted: 04/03/2023] [Indexed: 05/02/2023]
Abstract
BACKGROUND & AIMS Little is known about the potential impact of statins on the progression of noncirrhotic chronic liver diseases (CLDs) to severe liver disease. METHODS Using liver histopathology data in a nationwide Swedish cohort, we identified 3862 noncirrhotic individuals with CLD and statin exposure, defined as a statin prescription filled for 30 or more cumulative defined daily doses. Statin users were matched to 3862 (statin) nonusers with CLD through direct 1:1 matching followed by propensity score matching. Cox regression was used to estimate hazard ratios (HRs) for the primary outcome of incident severe liver disease (a composite of cirrhosis, hepatocellular carcinoma, and liver transplantation/liver-related mortality). RESULTS A total of 45.3% of CLD patients had nonalcoholic fatty liver disease, 21.9% had alcohol-related liver disease, 17.7% had viral hepatitis, and 15.1% had autoimmune hepatitis. During follow-up evaluation, 234 (6.1%) statin users vs 276 (7.1%) nonusers developed severe liver disease. Statin use was associated with a decreased risk of developing severe liver disease (HR, 0.60; 95% CI, 0.48-0.74). Statistically significantly lower rates of severe liver disease were seen in alcohol-related liver disease (HR, 0.30; 95% CI, 0.19-0.49) and in nonalcoholic fatty liver disease (HR, 0.68; 95% CI, 0.45-1.00), but not in viral hepatitis (HR, 0.76; 95% CI, 0.51-1.14) or autoimmune hepatitis (HR, 0.88; 95% CI, 0.48-1.58). Statin use had a protective association in both prefibrosis and fibrosis stages at diagnosis. Statin use was associated with lower rates of progression to cirrhosis (HR, 0.62; 95% CI, 0.49-0.78), hepatocellular carcinoma (HR, 0.44; 95% CI, 0.27-0.71), and liver-related mortality (HR, 0.55; 95% CI, 0.36-0.82). CONCLUSIONS Among individuals with noncirrhotic CLD, incident statin use was linked to lower rates of severe liver disease, suggesting a potential disease-modifying role.

Abstract
Autoimmune hepatitis is an immune-mediated inflammatory condition of the liver of undetermined cause that affects both sexes, all ages, races, and ethnicities. Its clinical presentation can be very broad, from having an asymptomatic and silent course to presenting as acute hepatitis, cirrhosis, and acute liver failure potentially requiring liver transplantation. The diagnosis is based on histological abnormalities (interface hepatitis), characteristic clinical and laboratory findings (increased aspartate aminotransferase, alanine aminotransferase, and serum IgG concentration), and the presence of one or more characteristic autoantibodies. The large heterogeneity of these clinical, biochemical, and histological findings can sometimes make a timely and proper diagnosis a difficult task. Treatment seeks to achieve remission of the disease and prevent further progression of liver disease. First-line therapy includes high-dose corticosteroids, which are later tapered to decrease side effects, and azathioprine. In the presence of azathioprine intolerance or a poor response to the standard of care, second-line therapy needs to be considered, including mycophenolate mofetil. AIH remains a diagnostic and therapeutic challenge, and a further understanding of the pathophysiological pathways of the disease and the implementation of randomized controlled trials are needed.

Abstract
The goal of autoimmune hepatitis treatment is to achieve clinical and biochemical remission, which is associated with significantly improved outcomes. Induction treatment with corticosteroids and the subsequent addition of steroid-sparing therapy with gradual tapering of corticosteroids remains the standard of care. Several alternatives to azathioprine and second-line agents, such as mycophenolate mofetil, tacrolimus, cyclosporine, sirolimus, or rituximab, have been evaluated in those with intolerance or inadequate response to standard-of-care therapy. Treatment withdrawal is achievable in less than 20% of patients after 2 years of sustained remission. Liver transplantation should be considered in those with progressive liver disease or those with complications such as hepatocellular carcinoma.

Abstract
BACKGROUND Autoimmune hepatitis (AIH) is a rare, chronic inflammatory disease of the liver. The treatment goal is reaching complete biochemical response (CR), defined as the normalisation of aspartate and alanine aminotransferases and immunoglobulin gamma. Ongoing AIH activity can lead to fibrosis and (decompensated) cirrhosis. Incomplete biochemical response is the most important risk factor for liver transplantation or liver-related mortality. First-line treatment consists of a combination of azathioprine and prednisolone. If CR is not reached, tacrolimus (TAC) or mycophenolate mofetil (MMF) can be used as second-line therapy. Both products are registered for the prevention of graft rejection in solid organ transplant recipients. The aim of this study is to compare the effectiveness and safety of TAC and MMF as second-line treatment for AIH. METHODS The TAILOR study is a phase IIIB, multicentre, open-label, parallel-group, randomised (1:1) controlled trial performed in large teaching and university hospitals in the Netherlands. We will enrol 86 patients with AIH who have not reached CR after at least 6 months of treatment with first-line therapy. Patients are randomised to TAC (0.07 mg/kg/day initially and adjusted by trough levels) or MMF (max 2000 mg/day), stratified by the presence of cirrhosis at inclusion. The primary endpoint is the difference in the proportion of patients reaching CR after 12 months. Secondary endpoints include the difference in the proportion of patients reaching CR after 6 months, adverse effects, difference in fibrogenesis, quality of life and cost-effectiveness. DISCUSSION This is the first randomised controlled trial comparing two second-line therapies for AIH. Currently, second-line treatment is based on retrospective cohort studies. The rarity of AIH is the main issue in clinical research for alternative treatment options. The results of this trial can be implemented in existing international clinical guidelines. TRIAL REGISTRATION ClinicalTrials.gov NCT05221411 . Retrospectively registered on 3 February 2022; EudraCT number 2021-003420-33. Prospectively registered on 16 June 2021.

World J Gastroenterol 2023; 29:5503-5525. [PMID: 37900994 PMCID: PMC10600811 DOI: 10.3748/wjg.v29.i39.5503] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Revised: 09/09/2023] [Accepted: 10/11/2023] [Indexed: 10/19/2023] Open
Abstract
BACKGROUND Noninvasive methods have been developed to detect fibrosis in many liver diseases due to the limits of liver biopsy. However, previous studies have focused primarily on chronic viral hepatitis and nonalcoholic fatty liver disease. The diagnostic value of transient elastography for autoimmune liver diseases (AILDs) is worth studying. AIM To compare the diagnostic accuracy of imaging techniques with serum biomarkers of fibrosis in AILD. METHODS The PubMed, Cochrane Library and EMBASE databases were searched. Studies evaluating the efficacy of noninvasive methods in the diagnosis of AILDs [autoimmune hepatitis (AIH), primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC)] were included. The summary area under the receiver operating characteristic curve (AUROC), diagnostic odds ratio, sensitivity and specificity were used to assess the accuracy of these noninvasive methods for staging fibrosis. RESULTS A total of 60 articles were included in this study, and the number of patients with AIH, PBC and PSC was 1594, 3126 and 501, respectively. The summary AUROC of transient elastography in the diagnosis of significant fibrosis, advanced fibrosis and cirrhosis in patients with AIH were 0.84, 0.88 and 0.90, respectively, while those in patients with PBC were 0.93, 0.93 and 0.91, respectively. The AUROC of cirrhosis for patients with PSC was 0.95. However, other noninvasive indices (aspartate aminotransferase to platelet ratio index, aspartate aminotransferase/alanine aminotransferase ratio, fibrosis-4 index) had corresponding AUROCs less than 0.80. CONCLUSION Transient elastography exerts better diagnostic accuracy in AILD patients, especially in PBC patients. The appropriate cutoff values for staging advanced fibrosis and cirrhosis ranged from 9.6 to 10.7 and 14.4 to 16.9 KPa for PBC patients.

Abstract
The C-X-C motif ligand 16, or CXCL16, is a chemokine that belongs to the ELR - CXC subfamily. Its function is to bind to the chemokine receptor CXCR6, which is a G protein-coupled receptor with 7 transmembrane domains. The CXCR6/CXCL16 axis has been linked to the development of numerous autoimmune diseases and is connected to clinical parameters that reflect disease severity, activity, and prognosis in conditions such as multiple sclerosis, autoimmune hepatitis, rheumatoid arthritis, Crohn's disease, and psoriasis. CXCL16 is expressed in various immune cells, such as dendritic cells, monocytes, macrophages, and B cells. During autoimmune diseases, CXCL16 can facilitate the adhesion of immune cells like monocytes, T cells, NKT cells, and others to endothelial cells and dendritic cells. Additionally, sCXCL16 can regulate the migration of CXCR6-expressing leukocytes, which includes CD8+ T cells, CD4+ T cells, NK cells, constant natural killer T cells, plasma cells, and monocytes. Further investigation is required to comprehend the intricate interactions between chemokines and the pathogenesis of autoimmune diseases. It remains to be seen whether the CXCR6/CXCL16 axis represents a new target for the treatment of these conditions.

Abstract
Autoimmune hepatitis (AIH) is characterized by immune-mediated hepatocyte injury resulting in the destruction of liver cells, causing inflammation, liver failure, and fibrosis. Pediatric (AIH) is an autoimmune inflammatory disease that usually requires immunosuppression for an extended period. Frequent relapses after treatment discontinuation demonstrate that current therapies do not control intrahepatic immune processes. This study describes targeted proteomic profiling data in patients with AIH and controls. A total of 92 inflammatory and 92 cardiometabolic plasma markers were assessed for (i) pediatric AIH versus controls, (ii) AIH type 1 versus type 2, (iii) AIH and AIH-autoimmune sclerosing cholangitis overlapping syndrome and (iv) correlations with circulating vitamin D levels in AIH. A total of 16 proteins showed a nominally significant differential abundance in pediatric patients with AIH compared to controls. No clustering of AIH subphenotypes based on all protein data was observed, and no significant correlation of vitamin D levels was observed for the identified proteins. The proteins that showed variable expression include CA1, CA3, GAS6, FCGR2A, 4E-BP1 and CCL19, which may serve as potential biomarkers for patients with AIH. CX3CL1, CXCL10, CCL23, CSF1 and CCL19 showed homology to one another and may be coexpressed in AIH. CXCL10 seems to be the central intermediary link for the listed proteins. These proteins were involved in relevant mechanistic pathways for liver diseases and immune processes in AIH pathogenesis. This is the first report on the proteomic profile of pediatric AIH. The identified markers could potentially lead to new diagnostic and therapeutic tools. Nevertheless, considering the complex pathogenesis of AIH, more extensive studies are warranted to replicate and validate the present study's findings.

Abstract
Autoimmune hepatitis (AIH) is an immune-mediated chronic inflammatory liver disease, characterized by hypergammaglobulinemia, the presence of specific autoantibodies, and typical abnormalities in liver histology. Prompt diagnosis and initiation of immunosuppressive treatment are necessary for both chronic and acute onset AIH to prevent progression to end-stage liver disease or fatal liver failure. However, the diagnosis of AIH is challenging mainly because of its heterogeneous clinical, serological and pathological features. Although portal lymphoplasmacytosis and interface hepatitis are the most typical histological features of AIH, many other histological features can be observed in AIH, including emperipolesis, hepatocyte rosettes, and Kupffer cell hyaline globules. Recent studies have questioned emperipolesis and hepatocyte rosette formation as typical features of AIH, and atypical clinical and histological presentations have also been recognized. This led an international working group to propose the modified AIH diagnostic criteria. However, it is well recognized that there are no pathognomonic characteristics that can be used to diagnose AIH and careful clinicopathological correlation is required to arrive at the correct diagnosis. The aim of this review is to summarize the histological features of AIH, its varied histopathologic spectrum, recent updates and major differential diagnoses in routine clinical practice.

[PMID: 36769672 PMCID: PMC9917971 DOI: 10.3390/jcm12031024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 01/20/2023] [Accepted: 01/24/2023] [Indexed: 01/31/2023] Open
Abstract
The aim of the study was the pioneering retrospective ultrastructural evaluation of respective forms of hepatic stellate cells (HSCs) and analysis of their crosstalk with other adjacent nonparenchymal cells (NPCs), especially Kupffer cells/macrophages (KCs/MPs), in pediatric autoimmune hepatitis (AIH). METHODS Ultrastructural assessment of the HSC population and NPCs was performed in transmission electron microscopy (TEM) using pretreatment liver biopsies from 25 children (8 boys and 17 girls) aged 4-17 with clinic-pathologically diagnosed untreated AIH. RESULTS Submicroscopic evaluation allowed easy identification of numerous HSCs in the form of transitory cells, i.e., T-HSCs, accompanied by signs of fibrosis. T-HSCs included cells with features of activation initiation (iHSCs) and activation perpetuation (pHSCs), indicating high HSC activation plasticity. The pHSCs were markedly elongated and mainly showed a distinct loss of lipid cytoplasmic material, expanded and dilated channels of granular endoplasmic reticulum, and linear bundles of microfilaments beneath the cell membrane. They were surrounded by usually mature collagen fibers. Frequently activated KCs/MPs adhered directly to T-HSCs. Between them, tight intercellular junctions were formed by means of point desmosomes. CONCLUSIONS Our qualitative TEM observations indicate a key role of T-HSCs in liver fibrogenesis in pediatric AIH, with the essential involvement of activated KCs/MPs that directly adhere to them. Tight intercellular junctions, being the ultrastructural exponent of the specific cellular mechanisms of the crosstalk between NPCs, can play a vital role in hepatic collagen fibroplasia. A better understanding of HSC population morphology at the ultrastructural level in AIH seems important not only to improve the disease morphological diagnostics but to also provide new insights into therapeutic interventions for the phenomenon of liver fibrogenesis.

Noninvasive Prediction of Outcomes in Autoimmune Hepatitis-Related Cirrhosis. Hepatol Commun 2022; 6:1392-1402. [PMID: 34989164 PMCID: PMC9134802 DOI: 10.1002/hep4.1889] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Revised: 12/02/2021] [Accepted: 12/06/2021] [Indexed: 12/19/2022] Open
Abstract
The value of noninvasive tools in the diagnosis of autoimmune hepatitis (AIH)-related cirrhosis and the prediction of clinical outcomes is largely unknown. We sought to evaluate (1) the utility of liver stiffness measurement (LSM) in the diagnosis of cirrhosis and (2) the performance of the Sixth Baveno Consensus on Portal Hypertension (Baveno VI), expanded Baveno VI, and the ANTICIPATE models in predicting the absence of varices needing treatment (VNT). A multicenter cohort of 132 patients with AIH-related cirrhosis was retrospectively analyzed. LSM and endoscopies performed at the time of cirrhosis diagnosis were recorded. Most of the patients were female (66%), with a median age of 54 years. Only 33%-49% of patients had a LSM above the cutoff points described for the diagnosis of AIH-related cirrhosis (12.5, 14, and 16 kPa). Patients with portal hypertension (PHT) had significantly higher LSM than those without PHT (15.7 vs. 11.7 kPa; P = 0.001), but 39%-52% of patients with PHT still had LSM below these limits. The time since AIH diagnosis negatively correlated with LSM, with longer time being significantly associated with a lower proportion of patients with LSM above these cutoffs. VNT was present in 12 endoscopies. The use of the Baveno VI, expanded Baveno VI criteria, and the ANTICIPATE model would have saved 46%-63% of endoscopies, but the latter underpredicted the risk of VNT. Conclusions: LSM cutoff points do not have a good discriminative capacity for the diagnosis of AIH-related cirrhosis, especially long-term after treatment initiation. Noninvasive tools are helpful to triage patients for endoscopy.

Growth differentiation factor 15 as a novel diagnostic and therapeutic marker for autoimmune hepatitis. Sci Rep 2022; 12:8759. [PMID: 35610317 PMCID: PMC9130300 DOI: 10.1038/s41598-022-12762-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Accepted: 05/16/2022] [Indexed: 11/26/2022] Open
Abstract
Growth differentiation factor 15 (GDF15) has been reported to be associated with fibrosis and cancer in liver disease. Diagnosis of autoimmune hepatitis (AIH) is often difficult because of the lack of specific markers. We investigated whether GDF15 is useful for diagnosing AIH and determined its therapeutic effects. We enrolled 171 Japanese patients as follows: AIH (n = 45), hepatitis B (HB) (n = 17), hepatitis C (HC) (n = 15), primary biliary cholangitis (PBC) (n = 20), and 74 healthy controls. Serum GDF15 levels were measured, and immunohistological analyses of GDF15 were performed using liver tissue of AIH patients. (1) GDF15 levels (pg/ml) were higher in AIH (1994.3 ± 1258.0) and HC (1568.0 ± 822.3) than in HB (953.2 ± 871.4), PBC (643.9 ± 247.0), and controls (475.3 ± 145.3) (p < 0.0001), as well as in cirrhosis patients (n = 31) than in non-cirrhosis patients (n = 66) (1926.6 ± 1026.0 vs. 1249.1 ± 1124.1, p < 0.0001). In non-cirrhosis patients, GDF15 levels were higher in AIH (1914.0 ± 1327.2) than in HC (955.7 ± 502.7), HB (519.3 ± 197.5), and PBC (643.9 ± 247.0) (p < 0.0001). (2) GDF15 was positively correlated with M2BPGi (r = 0.7728), total bilirubin (r = 0.6231), and PT-INR (r = 0.6332). (3) GDF15 levels could be used to distinguish AIH from other liver diseases in non-cirrhosis patients, with an area under the curve of 0.9373 (sensitivity 93.6%, specificity 79.3%, cut-off value 931.3). (4) GDF15 in AIH decreased after treatment. (5) Immunohistological analyses in AIH liver tissues revealed that GDF15 was strongly expressed in inflammatory cells, hepatic cytoplasm, and sinusoidal endothelial cells, but decreased after treatment. GDF15 is a novel diagnostic marker for AIH and is also expected to be a therapeutic marker for AIH.Clinical Trials Registration: The study protocol was approved by the institutional review board of Kurume University (Approval No.: 19049).

Abstract
Transforming growth factor-beta and interleukin 10 have diverse immune inhibitory properties that have restored homeostatic defense mechanisms in experimental models of autoimmune disease. The goals of this review are to describe the actions of each cytokine, review their investigational use in animal models and patients, and indicate their prospects as interventions in autoimmune hepatitis. English abstracts were identified in PubMed by multiple search terms. Full-length articles were selected for review, and secondary and tertiary bibliographies were developed. Transforming growth factor-beta expands the natural and inducible populations of regulatory T cells, limits the proliferation of natural killer cells, suppresses the activation of naïve CD8+ T cells, decreases the production of interferon-gamma, and stimulates fibrotic repair. Interleukin 10 selectively inhibits the CD28 co-stimulatory signal for antigen recognition and impairs antigen-specific activation of uncommitted CD4+ and CD8+ T cells. It also inhibits maturation of dendritic cells, suppresses Th17 cells, supports regulatory T cells, and limits production of diverse pro-inflammatory cytokines. Contradictory immune stimulatory effects have been associated with each cytokine and may relate to the dose and accompanying cytokine milieu. Experimental findings have not translated into successful early clinical trials. The recombinant preparation of each agent in low dosage has been safe in human studies. In conclusion, transforming growth factor-beta and interleukin 10 have powerful immune inhibitory actions of potential therapeutic value in autoimmune hepatitis. The keys to their therapeutic application will be to match their predominant non-redundant function with the pivotal pathogenic mechanism or cytokine deficiency and to avoid contradictory immune stimulatory actions.

Abstract
The pathophysiology of autoimmune disorders is multifactorial, where immune cell migration, adhesion, and lymphocyte activation play crucial roles in its progression. These immune processes are majorly regulated by adhesion molecules at cell–extracellular matrix (ECM) and cell–cell junctions. Integrin, a transmembrane focal adhesion protein, plays an indispensable role in these immune cell mechanisms. Notably, integrin is regulated by mechanical force and exhibit bidirectional force transmission from both the ECM and cytosol, regulating the immune processes. Recently, integrin mechanosensitivity has been reported in different immune cell processes; however, the underlying mechanics of these integrin-mediated mechanical processes in autoimmunity still remains elusive. In this review, we have discussed how integrin-mediated mechanotransduction could be a linchpin factor in the causation and progression of autoimmune disorders. We have provided an insight into how tissue stiffness exhibits a positive correlation with the autoimmune diseases’ prevalence. This provides a plausible connection between mechanical load and autoimmunity. Overall, gaining insight into the role of mechanical force in diverse immune cell processes and their dysregulation during autoimmune disorders will open a new horizon to understand this physiological anomaly.

Abstract
The ongoing coronavirus disease-2019 (COVID-19) pandemic has necessitated special considerations in the management of diseases. The way presence of pre-existing diseases or treatment for it predisposes to, alters course of, and changes the management of COVID-19, is of relevance and is being extensively studied. Autoimmune hepatitis (AIH) is unique in that it is an autoimmune disease mandating treatment with immunosuppressive drugs, as well as a liver disease with potential for varying degrees of underlying fibrosis. The use of immunosuppressive drugs could alter the risk of acquiring COVID-19, the clinical course and severity of COVID-19 and the degree of underlying liver fibrosis could alter the clinical outcomes of patients with COVID-19. In this review, we try to summarize key areas relevant in understanding and improving the clinical care of patients with AIH in the current pandemic. Special considerations required in the management of patients with AIH in COVID-19 hotspots have been outlined based on the current evidence.

Abstract
BACKGROUND Concurrent extrahepatic autoimmune disorders (CEHAID) are frequently observed in autoimmune hepatitis (AIH). It is not clear whether there is any prognostic significance of CEHAID on AIH. The aim of this study was to examine the prognostic impact of CEHAID and the correlation with the disease severity of AIH. METHODS This study included 65 hospitalized subjects who fulfilled the accepted criteria for AIH during an 8-year period (2009-2016). All records were manually screened for presence of associated autoimmune diseases. Disease severity of AIH was assessed by liver laboratory tests including the ratio of aspartate aminotransferase to alanine aminotransferase (AST/ALT) and liver histology. RESULTS Among the enrolled patients, 52 (80%) were female (median age 61 years, IQR 45-75). Fifty-six (86.2%) were classified as type-1 AIH. In 26 (40%) patients at least one additional extrahepatic autoimmune disease was diagnosed. Thirty-four subjects were referred to our hospital because of acute presentation of AIH (supposed by an acute elevation of hepatic enzymes) for subsequent liver biopsy resulting in initial diagnosis of AIH. This group was stratified into 3 subgroups: (A) AIH alone (n = 14); (B) overlap with primary biliary cirrhosis (PBC) / primary sclerosing cholangitis (PSC) (n = 11); and (C) with CEHAID (n = 9). AST/ALT ratio was the lowest in subgroup C (median 0.64, IQR 0.51-0.94; P = 0.023), compared to subgroup A (median 0.91, IQR 0.66-1.10) and subgroup B (median 1.10, IQR 0.89-1.36). Patients with AIH alone showed a trend to the highest grade of fibrosis (mean 2.3; 95% CI: 1.5-3.0) with no statistical significance compared to subjects with CEHAID (lowest grade of fibrosis; mean 1.5; 95% CI: 0.2-2.8; P = 0.380) whereas the ongoing inflammation was comparable. CONCLUSIONS AST/ALT ratio and extent of fibrosis were lower in subjects with AIH and CEHAID, compared to subjects with only AIH. Therefore, the occurrence of CEHAID might be a predictor for lower disease severity of newly diagnosed acute onset AIH, possibly caused by an earlier diagnosis or different modes of damage.

Abstract
Autoimmune hepatitis (AIH) is characterized by interface hepatitis, elevated serum alanine aminotransferase and aspartate aminotransferase levels, circulating autoantibodies, and elevated predominantly immunoglobulin G (IgG) levels. The goal in the treatment of autoimmune hepatitis (AIH) is complete disease remission. Here we took advantage of a large cohort of AIH patients to clarify predictors associated with biochemical and histological remission. Of 705 patients with complete follow-up, 569 (80.7%) patients achieved complete biochemical remission. Lower IgG levels (17.8 vs. 25 g/L, p < 0.001) and less liver cirrhosis (19.3% vs. 33.1%, p < 0.001) at diagnosis were observed in these patients. They also had lower serum IgG levels (13 vs. 18.9 g/L, p < 0.001) after 3 months of treatment. Histological remission was achieved in 69.4% of 160 patients with complete biochemical remission after 3 years of treatment. Patients with histological remission had lower IgG levels (16.2 vs. 20.1 g/L, p = 0.006) and Ishak fibrosis scores (3.4 vs. 4.1, p = 0.010) at diagnosis, and they appeared to achieve biochemical remission more rapidly (1 vs. 3 months, p < 0.001). Of note, patients with histological remission had higher frequency of fibrosis regression than those with persisting histological activity (87.5% vs. 60%, p = 0.004). In conclusion, lower serum IgG levels, less fibrosis in liver histology at diagnosis, and rapid response to immunosuppressive therapy are reliable predictors of biochemical and histological remission. Our study underscores the importance of early diagnosis and appropriate treatment.

Abstract
BACKGROUND Cirrhosis and other chronic liver diseases (collectively referred to as cirrhosis in this paper) are a major cause of morbidity and mortality globally, although the burden and underlying causes differ across locations and demographic groups. We report on results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 on the burden of cirrhosis and its trends since 1990, by cause, sex, and age, for 195 countries and territories. METHODS We used data from vital registrations, vital registration samples, and verbal autopsies to estimate mortality. We modelled prevalence of total, compensated, and decompensated cirrhosis on the basis of hospital and claims data. Disability-adjusted life-years (DALYs) were calculated as the sum of years of life lost due to premature death and years lived with disability. Estimates are presented as numbers and age-standardised or age-specific rates per 100 000 population, with 95% uncertainty intervals (UIs). All estimates are presented for five causes of cirrhosis: hepatitis B, hepatitis C, alcohol-related liver disease, non-alcoholic steatohepatitis (NASH), and other causes. We compared mortality, prevalence, and DALY estimates with those expected according to the Socio-demographic Index (SDI) as a proxy for the development status of regions and countries. FINDINGS In 2017, cirrhosis caused more than 1·32 million (95% UI 1·27-1·45) deaths (440 000 [416 000-518 000; 33·3%] in females and 883 000 [838 000-967 000; 66·7%] in males) globally, compared with less than 899 000 (829 000-948 000) deaths in 1990. Deaths due to cirrhosis constituted 2·4% (2·3-2·6) of total deaths globally in 2017 compared with 1·9% (1·8-2·0) in 1990. Despite an increase in the number of deaths, the age-standardised death rate decreased from 21·0 (19·2-22·3) per 100 000 population in 1990 to 16·5 (15·8-18·1) per 100 000 population in 2017. Sub-Saharan Africa had the highest age-standardised death rate among GBD super-regions for all years of the study period (32·2 [25·8-38·6] deaths per 100 000 population in 2017), and the high-income super-region had the lowest (10·1 [9·8-10·5] deaths per 100 000 population in 2017). The age-standardised death rate decreased or remained constant from 1990 to 2017 in all GBD regions except eastern Europe and central Asia, where the age-standardised death rate increased, primarily due to increases in alcohol-related liver disease prevalence. At the national level, the age-standardised death rate of cirrhosis was lowest in Singapore in 2017 (3·7 [3·3-4·0] per 100 000 in 2017) and highest in Egypt in all years since 1990 (103·3 [64·4-133·4] per 100 000 in 2017). There were 10·6 million (10·3-10·9) prevalent cases of decompensated cirrhosis and 112 million (107-119) prevalent cases of compensated cirrhosis globally in 2017. There was a significant increase in age-standardised prevalence rate of decompensated cirrhosis between 1990 and 2017. Cirrhosis caused by NASH had a steady age-standardised death rate throughout the study period, whereas the other four causes showed declines in age-standardised death rate. The age-standardised prevalence of compensated and decompensated cirrhosis due to NASH increased more than for any other cause of cirrhosis (by 33·2% for compensated cirrhosis and 54·8% for decompensated cirrhosis) over the study period. From 1990 to 2017, the number of prevalent cases more than doubled for compensated cirrhosis due to NASH and more than tripled for decompensated cirrhosis due to NASH. In 2017, age-standardised death and DALY rates were lower among countries and territories with higher SDI. INTERPRETATION Cirrhosis imposes a substantial health burden on many countries and this burden has increased at the global level since 1990, partly due to population growth and ageing. Although the age-standardised death and DALY rates of cirrhosis decreased from 1990 to 2017, numbers of deaths and DALYs and the proportion of all global deaths due to cirrhosis increased. Despite the availability of effective interventions for the prevention and treatment of hepatitis B and C, they were still the main causes of cirrhosis burden worldwide, particularly in low-income countries. The impact of hepatitis B and C is expected to be attenuated and overtaken by that of NASH in the near future. Cost-effective interventions are required to continue the prevention and treatment of viral hepatitis, and to achieve early diagnosis and prevention of cirrhosis due to alcohol-related liver disease and NASH.

Abstract
BACKGROUND Acoustic radiation force impulse (ARFI) imaging is an ultrasound-based elastography method that has been studied in the staging of hepatic fibrosis, especially in chronic hepatitis. However, the diagnostic accuracy of ARFI in non-viral hepatopathies, such as autoimmune hepatitis and non-alcoholic fatty liver disease, has not been systematically determined. AIM To systematically assess the diagnostic accuracy of ARFI in non-viral hepatopathies. METHODS The databases of PubMed, Embase, Cochrane Library and clinicaltrials.gov were systematically searched for candidate studies reporting the diagnostic accuracy of ARFI for hepatic fibrosis. The pooled estimates of the sensitivity, specificity, diagnostic odds ratio, and positive and negative likelihood ratios were calculated with the summary receiver operating curve (sROC) performed using STATA software. RESULTS In detail, a total of 29 diagnostic studies were included for further analysis. The quality of the included studies was relatively high using QUADAS method. The pooled sensitivity and specificity were 0.79 (0.73, 0.83) and 0.81 (0.75, 0.86), with AUROC 0.87 (0.83, 0.89) for the staging of significant fibrosis (F≥2). Meanwhile, for the staging of severe fibrosis (F≥3), the pooled sensitivity and specificity were 0.92 (0.87, 0.95) and 0.85 (0.80, 0.89), with AUROC 0.94 (0.92, 0.96). Furthermore, the pooled sensitivity and specificity were 0.89 (0.79, 0.95) and 0.89 (0.85, 0.92), with AUROC 0.94 (0.92, 0.96) for ARFI in staging cirrhosis (F = 4), which were similar to the data for severe fibrosis. No significant publication bias was present in this study. CONCLUSION This meta-analysis demonstrated that ARFI exerted satisfactory diagnostic performance in staging non-viral hepatic fibrosis, especially severe fibrosis (F≥3) and cirrhosis (F = 4).

Abstract
BACKGROUND AND AIMS Non-invasive fibrosis assessment has been highly recommended in many liver diseases. However, comparative diagnostic accuracy of laboratory markers, ultrasound and magnetic resonance elastography (MRE) for fibrosis in autoimmune hepatitis (AIH) patients has not been established. METHODS Medline, Embase and Cochrane Library were searched. Primary outcome was significant fibrosis (SF), advanced fibrosis (AF) and cirrhosis, defined as Metavir stage F ≥ 2, F ≥ 3 and F = 4 according to liver biopsy. Hierarchical summary receiver operating characteristic curve (ROC) model was used to evaluate diagnostic accuracy of non-invasive methods. Summary area under ROC (AUROC) and diagnostic odds ratio (DOR) with 95% confidence interval (CI) were calculated. The Grading of Recommendations Assessment, Development and Evaluation system was used to assess quality of evidence. RESULTS Overall, 16 studies with 861 patients were included, comparing aspartate aminotransferase to platelet ratio index (APRI), fibrosis-4 index (FIB-4), aspartate aminotransferase/alanine aminotransferase ratio, transient elastography (TE), acoustic radiation force impulse, shear wave elastography and MRE versus liver biopsy. Among all non-invasive markers, TE had good performance for fibrosis staging. Summary AUROCs and DORs of TE were 0.90 (95% CI 0.87, 0.92) and 23.7, 0.91 (95% CI 0.89, 0.93) and 31.6, 0.89 (95% CI 0.86, 0.92) and 80.5 for staging SF, AF and cirrhosis, whereas APRI and FIB-4 showed poor performance for detecting AF (DOR, 4.6 and 4.7) and cirrhosis (DOR, 5.5 and 12.9). CONCLUSIONS TE performs well to stage liver fibrosis in patients with AIH, compared with other laboratory non-invasive indexes. Nevertheless, diagnostic accuracy of APRI and FIB-4 is poor.

Abstract
Autoimmune hepatitis (AIH) may present as acute or chronic hepatitis in the elderly. Advanced hepatic fibrosis and cirrhosis are common on first presentation in this population. In this review, we discuss the presentation, approach to diagnosis and management of AIH in the elderly. As polypharmacy is common in the elderly, careful medication use history is essential for detecting drug-induced AIH-like hepatitis. Steroid-sparing or minimizing therapeutic regimens are preferred to treat AIH in the elderly. For the purpose of induction, budesonide or lower dose prednisone in combination with azathioprine (AZA) regimens are preferred over high-dose prednisone monotherapy due to the higher risk of side effects of the later in the elderly. The goal of maintenance therapy should be to achieve full biochemical and histologic remission. Bone density monitoring and interventions to prevent steroid-related bone disease should be implemented throughout the course of the disease. Liver transplantation should be considered in the elderly patient with liver failure or early hepatocellular carcinoma if there are no significant comorbidities or compromise in functional status.

Abstract
Autoimmune hepatitis lacks a quantifiable biomarker that is close to its pathogenic mechanisms and that accurately reflects inflammatory activity, correlates with treatment response, and ensures inactive disease before treatment withdrawal. Areas covered: Micro-ribonucleic acids, programmed death-1 protein and its ligands, macrophage migration inhibitory factor, soluble CD163, B cell activating factor, and metabolite patterns in blood were considered the leading candidates as therapeutic biomarkers after search of PubMed from August 1981 to August 2017 using the search words 'biomarkers of autoimmune hepatitis'. Expert commentary: Each of the candidate biomarkers is close to the putative pathogenic mechanisms of autoimmune hepatitis, and each has attributes that support its potential role as a surrogate marker of inflammatory activity that can be monitored during treatment. Future studies must demonstrate the superiority of each biomarker to conventional indices of inflammatory activity and validate their correlation with treatment response and outcome. A reliable therapeutic biomarker would facilitate the individualization of current management algorithms, ensure that pathogenic mechanisms were disrupted or eliminated prior to treatment withdrawal, and reduce the frequency of relapse or unnecessary protracted therapy. The biomarker might also prove to be a target of next-generation therapies.

Abstract
The most suitable treatment regimen for autoimmune hepatitis (AIH) in adults remains unknown and requires further investigation. The current study therefore aimed to integrate evidence to provide hierarchies of the comparative efficacies of treatments measured by clinical and biochemical remission. A Bayesian-framework network meta-analysis of randomized controlled trials (RCTs) was preformed to compare eight treatments for AIH. Eligible RCTs were identified by searching Embase, Pubmed and the Cochrane Library for publications between 1966 and April 2017. All outcomes were independently extracted from the included studies by two authors. A total of six RCTs were subsequently included in the current study. The network of comparisons on remission indicated that patients treated with prednisone (pred) experienced significantly increased rates of remission compared with those treated with azathioprine [AZA; odds ratio (OR), 0.21; 95% confidence interval (CI), 0.06-0.71] and budesonide (bude) + AZA significantly increased remission compared with placebo treatment (OR, 36.66; 95% CI, 1.40-962.49) or AZA (OR, 10.30; 95% CI, 1.50-70.70). Based on the cumulative ranking probabilities, bude + AZA (89.4) was ranked first, pred (69.1) was ranked second, pred + AZA (63.2) was ranked third and placebo (7.8) treatment was ranked last. Bude + AZA may be the most appropriate candidate for the treatment of non-cirrhotic patients. However, bude + AZA as frontline therapy for AIH requires more large-scale studies with a longer duration of follow-up histology and a focus on dose-response. Additionally, development of other prospective treatments, which may be used as alternative therapy or first line therapy, and their subsequent evaluation in clinical RCTs is required.

Abstract
Ultrasound findings in autoimmune hepatitis (AIH) have not been reported systematically so far. The use of reliable and accurate noninvasive methods for determining fibrosis stage is important in evaluation of treatment efficacy and fibrosis regression in AIH. Imaging plays an important role in detection of complications and ruling out other possible causes of chronic liver diseases. Ultrasound elastography cut-off values in AIH patients are not the same as those in patients with chronic viral hepatitis or non-alcoholic fatty liver disease. AIH is characterized by wide fluctuations in inflammatory activity. Here we report on current knowledge of ultrasound findings in AIH.

Usefulness of biochemical remission and transient elastography in monitoring disease course in autoimmune hepatitis. J Hepatol 2018; 68:754-763. [PMID: 29180000 DOI: 10.1016/j.jhep.2017.11.020] [Citation(s) in RCA: 74] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2017] [Revised: 11/07/2017] [Accepted: 11/10/2017] [Indexed: 12/14/2022]
Abstract
BACKGROUND & AIMS Liver fibrosis regression but also progression may occur in patients with autoimmune hepatitis (AIH) under treatment. There is a need for non-invasive surrogate markers for fibrosis development in AIH to better guide immunosuppressive treatment. The aims of the study were to assess the impact of complete biochemical remission defined as normalisation of aminotransferases and IgG on histological activity and fibrosis development, and the value of repeat transient elastography (TE) measurement for monitoring disease progression in AIH. METHODS A total of 131 liver biopsies from 60 patients with AIH and more than 900 TE from 125 patients with AIH, 130 with primary biliary cholangitis (PBC) and 100 with primary sclerosing cholangitis (PSC), were evaluated. Time intervals between TE were at least 12 months. Patients with AIH were treated for at least six months at first TE. RESULTS In contrast to PBC and PSC, a decrease of liver stiffness (LS) was observed in the whole group of patients with AIH (-6.2%/year; 95% CI -12.6% to -0.2%; p = 0.04). The largest decrease of LS was observed in patients with severe fibrosis at baseline (F4: -11.7%/year; 95% CI -19% to -3.5%; p = 0.006). Complete biochemical remission was strongly linked to regression of LS ("remission": -7.5%/year vs. "no remission": +1.7%/year, p <0.001). Similarly, complete biochemical remission predicted low histological disease activity and was the only independent predictor for histological fibrosis regression (relative risk3.66; 95% CI1.54-10.2; p = 0.001). Patients with F3/F4-fibrosis, who remained in biochemical remission showed a considerable decrease of fibrosis stage (3.7 ± 0.5 to 1.8 ± 1.7; p = 0.007) on histological follow-up. CONCLUSIONS This study demonstrates that complete biochemical remission is a reliable predictor of a good prognosis in AIH and leads to fibrosis regression that can be monitored by TE. LAY SUMMARY Autoimmune hepatitis is an inflammatory disease of the liver, which often progresses to cirrhosis if left untreated or in the case of insufficient treatment response. Current guidelines have defined biochemical remission (normalisation of biochemical markers for liver inflammation) as a major goal in the treatment of AIH. However, data on the prognostic relevance of this definition are scarce. Herein, we demonstrate that the current definition of biochemical remission is a reliable surrogate for low disease activity on histological assessment and for a beneficial long-term disease course. In addition, we establish transient elastography, a non-invasive ultrasound-based method of measuring scarring of liver tissue, as a reliable tool to monitor disease course in AIH.

Abstract
BACKGROUND AND AIMS Advanced liver fibrosis is an important predictor of liver disease progression and mortality, and current guidelines recommend screening for complications of cirrhosis once patients develop F3 fibrosis. Our study compared liver disease progression and survival in patients with stage 3 (F3) and stage 4 (F4) fibrosis on liver biopsy. METHODS Retrospective study of patients with F3 or F4 on liver biopsy followed for development of liver disease complications (variceal bleeding, ascites, and hepatic encephalopathy); hepatocellular carcinoma, and survival (overall and transplant free survival). RESULTS Of 2488 patients receiving liver biopsy between 01/02 and 12/12, a total of 294 (171 F3) were analyzed. Over a median follow up period of 3 years, patients with F4 (mean age 53 years, 63% male) compared to F3 (mean age 49 years, 43% male) had higher five year cumulative probability of any decompensation (38% vs. 14%, p<0.0001), including variceal bleed (10% vs. 4%, p = 0.014), ascites (21% vs. 9%, p = 0.0014), and hepatic encephalopathy (14% vs. 5%, p = 0.003). F4 patients also had lower overall 5-year survival (80% vs. 93%, p = 0.003) and transplant free survival (80% vs. 93%, p = 0.002). Probability of hepatocellular carcinoma in 5 years after biopsy was similar between F3 and F4 (1.2% vs. 2%, p = 0.54). CONCLUSIONS Compared to F4 stage, patients with F3 fibrosis have decreased risk for development of liver disease complications and better survival. Prospective well designed studies are suggested with large sample size and overcoming the limitations identified in this study, to confirm and validate these findings, as basis for modifying guidelines and recommendations on follow up of patients with advanced fibrosis and stage 3 liver fibrosis.

BMSCs-derived miR-223-containing exosomes contribute to liver protection in experimental autoimmune hepatitis. Mol Immunol 2017; 93:38-46.

Abstract
Autoimmune hepatitis is a chronic inflammatory disease in the liver with potential to the development of liver fibrosis. Recent evidences suggest that bone marrow derived mesenchymal stem cells (BMSCs) may exert its therapeutic activity through exosomes. Moreover, miR-223 is highly expressed in BMSCs and plays an important role in autoimmune diseases. Therefore, in this study, hepatoprotective role of BMSCs and miR-223 was investigated in both mice and hepatocytes. Liver antigen S100 was used to establish autoimmune hepatitis model in mice while LPS and ATP were used to establish cell injury model in hepatocyte. Before the experiments, BMSCs were infected with pre-miR-223 and transfected with miR-223 inhibitor respectively. Exosomes from bone marrow stem cells were isolated by ultracentrifugation. Liver injury was evaluated by serum levels of ALT and AST as well as liver histology. Inflammation and cell death were examined by inflammatory cytokines and lactase dehydrogenase respectively. Both BMSCs-exo and BMSCs-exomiR-223(+) significantly reversed either S100 or LPS/ATP induced injury in mice and hepatocytes. Meanwhile, the expressions of cytokines, NLRP3 and caspase-1 were also downregulated by BMSCs-exo and BMSCs-exomiR-223(+) at both protein and mRNA levels in mice and hepatocytes. Moreover, BMSCs-exomiR-223(-) reverses the effects of BMSCs-exo and BMSCs-exomiR-223(+) in mouse AIH and in hepatocytes. In conclusion, bone marrow stem cell derived exosomes can protect liver injury in an experimental model of autoimmune hepatitis and the mechanism could be related to exosomal miR-223 regulation of NLRP3 and caspase-1.

Abstract
Autoimmune hepatitis (AIH) is a chronic autoimmune liver disease that if left untreated may lead to the development of cirrhosis. Previous studies on AIH patients have suggested that fibrosis and even cirrhosis can be reversed by medical treatment. The aim of this study was to evaluate the efficacy of medical treatment for protection of developing fibrosis and cirrhosis.A total of 258 liver biopsies from 101 patients (72 women, 29 men) were analyzed by a single pathologist and classified according to the Ishak grading (inflammation) and staging (fibrosis) system. Liver histology was stratified according to the temporal changes of fibrosis stage (increased, decreased, or stable), and groups were compared.Complete or partial response to medical treatment was 94.9%. Reduction of fibrosis stage from the first to the last biopsy was seen in 63 patients (62.4%). We found an association between a reduction in the fibrosis stage and continuous glucocorticoid medication, as well as lowered scores of inflammation at last biopsy. Twenty-one patients had cirrhosis (Ishak stage 6) at least in one of the previous biopsies, but only 5 patients at the last biopsy.Histological improvement is common in AIH patients that respond to medical treatment, and a reduction or stabilization of fibrosis stage occurs in about 2/3 of such patients.

Abstract
Case summary A 6-month-old cat was successfully treated for bilateral quadriceps contracture. Conventional treatments including surgery, dynamic flexion apparatus and physical therapy along with analgesics and non-steroidal anti-inflammatory drugs resulted in temporary clinical improvement that was relapsing. The initiation of supplementary corticosteroid treatment with prednisolone coincided with an immediate and sustained clinical improvement and long-term resolution. Relevance and novel information Successful treatment of bilateral quadriceps contracture has not previously been reported in a cat. Quadriceps contracture remains a challenging condition to treat with some cases unresponsive to therapy. Systemic prednisolone treatment appeared to be of benefit in the management of this case and may have a role in some cats where muscle contracture appears relapsing in nature. Further prospective investigations in cats with muscle contracture, including muscle biopsies of affected cats, are warranted.

Abstract
AIM To evaluate the clinical effects of Yinzhihuang injection in the treatment of patients with autoimmune hepatitis (AIH)and its effect on indexes of hepatic fibrosis.
METHODS Seventy-four patients with AIH treated at our hospital between April 2013 and November 2015 were randomly divided into either a control group or an observation group, with 37 cases in each group. Both groups were given oral prednisone and azathioprine, and the observation group was additionally given Yinzhihuang injection. The clinical indicators, clinical curative effects and adverse reactions of the two groups were compared.
RESULTS After treatment, serum alanine aminotransferase, aspartate transaminase, glutamyl transpeptidase, total bilirubin, glyoxalase and albumin in the observation group were significantly lower than those in the control group (t = 5.056, 8.186, 7.254, 3.959, 2.928, and 2.460, respectively; P < 0.05); liver fiber indexes collagen Ⅳ, hyaluronan, procollagen Ⅲ peptide, and laminin in the observation group were significantly lower than those of the control group (t = 8.043, 12.692, 4.858, and 8.683, respectively; P < 0.05); and the ratio of CD4+ T cells/CD8+ T cells was significantly lower in the observation group than in the control group (t = 2.708, P < 0.05). The total effective rate in the observation group (89.19%) was significantly higher than that of the control group (64.86%) (χ2 = 6.186, P = 0.013). The overall incidence of adverse reactions in the observation group was significantly lower than that of the control group (5.41% vs 21.62%, χ2 = 4.163, P = 0.041).
CONCLUSION Yinzhihuang injection combined with Western medicine can significantly improve clinical efficacy and liver fiber indexes, and reduce adverse reactions in patients with AIH.

Abstract
In the past, liver cirrhosis was considered an irreversible phenomenon. However, many experimental data have provided evidence of the reversibility of liver fibrosis. Moreover, multiple clinical studies have also shown regression of fibrosis and reversal of cirrhosis on repeated biopsy samples. As various etiologies are associated with liver fibrosis via integrated signaling pathways, a comprehensive understanding of the pathobiology of hepatic fibrogenesis is critical for improving clinical outcomes. Hepatic stellate cells play a central role in hepatic fibrogenesis upon their activation from a quiescent state. Collagen and other extracellular material components from activated hepatic stellate cells are deposited on, and damage, the liver parenchyma and vascular structures. Hence, inactivation of hepatic stellate cells can lead to enhancement of fibrolytic activity and could be a potential target of antifibrotic therapy. In this regard, continued efforts have been made to develop better treatments for underlying liver diseases and antifibrotic agents in multiple clinical and therapeutic trials; the best results may be expected with the integration of such evidence. In this article, we present the underlying mechanisms of fibrosis, current experimental and clinical evidence of the reversibility of liver fibrosis/cirrhosis, and new agents with therapeutic potential for liver fibrosis.

Abstract
AIM To assess the value of magnetic resonance elastography (MRE) in detecting advanced fibrosis/cirrhosis in autoimmune hepatitis (AIH).
METHODS In this retrospective study, 36 patients (19 treated and 17 untreated) with histologically confirmed AIH and liver biopsy performed within 3 mo of MRE were identified at a tertiary care referral center. Liver stiffness (LS) with MRE was calculated by a radiologist, and inflammation grade and fibrosis stage in liver biopsy was assessed by a pathologist in a blinded fashion. Two radiologists evaluated morphological features of cirrhosis on conventional magnetic resonance imaging (MRI). Accuracy of MRE was compared to laboratory markers and MRI for detection of advanced fibrosis/cirrhosis.
RESULTS Liver fibrosis stages of 0, 1, 2, 3 and 4 were present in 4, 6, 7, 6 and 13 patients respectively. There were no significant differences in distribution of fibrosis stage and inflammation grade between treated and untreated patient groups. LS with MRE demonstrated stronger correlation with liver fibrosis stage in comparison to laboratory markers for chronic liver disease (r = 0.88 vs -0.48-0.70). A trend of decreased mean LS in treated patients compared to untreated patients was observed (3.7 kPa vs 3.84 kPa) but was not statistically significant. MRE had an accuracy/sensitivity/specificity/positive predictive value/negative predictive value of 0.97/90%/100%/100%/90% and 0.98/92.3%/96%/92.3%/96% for detection of advanced fibrosis and cirrhosis, respectively. The performance of MRE was significantly better than laboratory tests for detection of advanced fibrosis (0.97 vs 0.53-0.80, P < 0.01), and cirrhosis (0.98 vs 0.58-0.80, P < 0.01) and better than conventional MRI for diagnosis of cirrhosis (0.98 vs 0.78, P = 0.002).
CONCLUSION MRE is a promising modality for detection of advanced fibrosis and cirrhosis in patients with AIH with superior diagnostic accuracy compared to laboratory assessment and MRI.

Abstract
Hepatic fibrosis develops or progresses in 25 % of patients with autoimmune hepatitis despite corticosteroid therapy. Current management regimens lack reliable noninvasive methods to assess changes in hepatic fibrosis and interventions that disrupt fibrotic pathways. The goals of this review are to indicate promising noninvasive methods to monitor hepatic fibrosis in autoimmune hepatitis and identify anti-fibrotic interventions that warrant evaluation. Laboratory methods can differentiate cirrhosis from non-cirrhosis, but their accuracy in distinguishing changes in histological stage is uncertain. Radiological methods include transient elastography, acoustic radiation force impulse imaging, and magnetic resonance elastography. Methods based on ultrasonography are comparable in detecting advanced fibrosis and cirrhosis, but their performances may be compromised by hepatic inflammation and obesity. Magnetic resonance elastography has excellent performance parameters for all histological stages in diverse liver diseases, is uninfluenced by inflammatory activity or body habitus, has been superior to other radiological methods in nonalcoholic fatty liver disease, and may emerge as the preferred instrument to evaluate fibrosis in autoimmune hepatitis. Promising anti-fibrotic interventions are site- and organelle-specific agents, especially inhibitors of nicotinamide adenine dinucleotide phosphate oxidases, transforming growth factor beta, inducible nitric oxide synthase, lysyl oxidases, and C-C chemokine receptors types 2 and 5. Autoimmune hepatitis has a pro-fibrotic propensity, and noninvasive radiological methods, especially magnetic resonance elastography, and site- and organelle-specific interventions, especially selective antioxidants and inhibitors of collagen cross-linkage, may emerge to strengthen current management strategies.

Abstract
Oxidative and nitrosative stresses can damage cellular membranes, disrupt mitochondrial function, alter gene expression, promote the apoptosis and necrosis of hepatocytes, and increase fibrosis in diverse acute and chronic liver diseases, including autoimmune hepatitis. The objectives of this review are to describe the mechanisms of oxidative and nitrosative stresses in inflammatory liver disease, indicate the pathogenic implications of these stresses in autoimmune hepatitis, and suggest investigational opportunities to develop interventions that counter them. The principal antioxidant defenses, including glutathione production, the activities of antioxidant enzymes, and the release of the nuclear factor erythroid 2-related factor 2, may be inadequate or suppressed by transforming growth factor beta. The generation of reactive oxygen species can intensify nitrosative stress, and this stress may not be adequately modulated by the thioredoxin-thioredoxin reductase system and induce post-translational modifications of proteins that further disrupt hepatocyte function. The unfolded protein response and autophagy may be unable to restore redox stability, meet metabolic demands, and maintain hepatocyte survival. Emerging interventions with highly selective site- and organelle-specific actions may improve outcomes, and they include inhibitors of nicotinamide adenine dinucleotide phosphate oxidase, nitric oxide synthase, and transforming growth factor beta. Pharmacological manipulation of nuclear transcription factors may favor expression of antioxidant genes, and stimulation of chaperone proteins within the endoplasmic reticulum and modulation of autophagy may prevent hepatic fibrosis and enhance cell survival. These interventions constitute investigational opportunities to improve the management of autoimmune hepatitis.

Abstract
Liver biopsy is recommended to establish the diagnosis and to assess remission in autoimmune hepatitis (AIH) patients. The aim of our study was to assess the utility of repeat biopsy in AIH. Forty liver biopsies from 20 consecutive AIH patients who underwent repeat biopsy were evaluated. We assessed the biopsies for histological findings other than AIH and how often the repeat biopsy led to a change in clinical management. Furthermore, we correlated the changes in the laboratory findings with the histological features. AIH patients in the study were mostly female (80%; average age 58.7 years). The most common indications for repeat biopsy included elevated transaminases (40%) and evaluation prior to treatment alteration (40%). Seventy percent of the patients showed improved aminotransferase levels, which demonstrated no significant correlation with the inflammatory (p = 1.000) or fibrosis progression (p = 0.116). Forty percent of the patients showed pathology other than AIH in the repeat biopsies (3 steatohepatitis; 5 cholangiopathy features). Changes in the management were seen in all patients. Repeat biopsy is important in AIH patients as aminotransferase levels are not always a reliable marker for inflammatory and fibrosis progression. Moreover, liver biopsy is an effective method for diagnosing comorbid liver conditions.

Abstract
BACKGROUND Abundant experimental evidence indicates overproduction of angiotensin II in the injured liver, and a role in stimulation of hepatic stellate cell (HSC) activation and fibrogenesis thereby, representing an attractive antifibrotic target. The aim of this study was to examine the antifibrotic effect of losartan on histopathologic level in chronic HCV patients. METHODS A prospective study on fifty patients with chronic HCV and liver fibrosis proved by liver biopsy was conducted. They included patients who did not respond (n=36) or comply (n=2) or receive therapy due to established cirrhosis (n=10), or refused to receive (n=2) combined interferon and ribavirin therapy. They were divided randomly into 2 groups. The 1(st) group (n=25) was given losartan 50 mg OD for 1 year and the 2(nd) group (25 patients) was given silymarin, 140 mg t.i.d., (silymarin group). Liver biopsy was done at baseline and 1 year from the onset of treatment (end of study). RESULTS In the second liver biopsy after 1 year, the decrease in fibrosis stage was significantly different between losartan group and silymarin group (a decrease of 1.88±0.96 (50.9%) vs. 0.45±0.93 (11.7%), respectively; P<0.01). In patients treated with losartan, regression in fibrosis stage was observed in 14/16 patients vs. 2/11 in silymarin group (P<0.01). No differences were observed in inflammation grades in both groups. A significant increase in albumin and prothrombin levels and a decrease in systolic blood pressure were found in losartan but not in silymarin group (P=0.009, 0.001 & 0.018 respectively and P=0.158, 0.603 & 0.288, respectively). CONCLUSIONS Histopathological scores showed that losartan had an inhibitory effect on progression and even led to regression of fibrosis stage but had no effect on the grade of inflammation.

Clinical significance of serum Wisteria floribunda agglutinin positive Mac-2-binding protein level and high-sensitivity C-reactive protein concentration in autoimmune hepatitis. Hepatol Res 2016; 46:613-21.

Abstract
AIM We aimed to examine the relationship between the Wisteria floribunda agglutinin positive Mac-2-binding protein (WFA(+) -M2BP) level and high-sensitivity C-reactive protein (hCRP) concentration and liver histological findings for patients with autoimmune hepatitis (AIH). METHODS A total of 84 AIH patients (median age, 64 years) were analyzed. We examined the effect of pretreatment WFA(+) -M2BP level and hCRP concentration on histological findings of liver fibrosis and liver inflammation activity comparing with other laboratory markers. Receiver-operator curve (ROC) analysis was performed for calculating the area under the ROC (AUROC). RESULTS The median WFA(+) -M2BP values in each fibrosis stage were: 1.5 cut-off index (COI) in F1, 2.1 in F2, 3.3 in F3 and 9.8 in F4 (P < 0.001). The median WFA(+) -M2BP values in each liver inflammation stage were: 1.6 COI in A1, 2.5 in A2 and 5.4 in A3 (P < 0.001). For predicting liver cirrhosis (F4), WFA(+) -M2BP yielded the highest AUROC (0.853). For predicting advanced liver fibrosis (F3 or F4), WFA(+) -M2BP, FIB-4 index and hyaluronic acid yielded the highest AUROC (0.747). For predicting severe liver inflammation activity (A3), WFA(+) -M2BP yielded the highest AUROC (0.739). The hCRP concentration in patients with A3 (median, 2230 ng/mL) was significantly higher than that in patients with A1 or A2 (median, 854.5 ng/mL) (P < 0.01). WFA(+) -M2BP level significantly correlated with hCRP concentration (rs = 0.461, P < 0.001). CONCLUSION WFA(+) -M2BP can be a useful marker for assessing liver histological findings in AIH patients and it correlated well with hCRP concentration.

Abstract
Autoimmune hepatitis is characterized by autoantibodies, hypergammaglobulinemia, and interface hepatitis on histological examination. The features lack diagnostic specificity, and other diseases that may resemble autoimmune hepatitis must be excluded. The clinical presentation may be acute, acute severe (fulminant), or asymptomatic; conventional autoantibodies may be absent; centrilobular necrosis and bile duct changes may be present; and the disease may occur after liver transplantation or with features that suggest overlapping disorders. The diagnostic criteria have been codified, and diagnostic scoring systems can support clinical judgment. Nonstandard autoantibodies, including antibodies to actin, α-actinin, soluble liver antigen, perinuclear antineutrophil antigen, asialoglycoprotein receptor, and liver cytosol type 1, are tools that can support the diagnosis, especially in patients with atypical features. Prednisone or prednisolone in combination with azathioprine is the preferred treatment, and strategies using these medications in various doses can ameliorate treatment failure, incomplete response, drug intolerance, and relapse after drug withdrawal. Budesonide, mycophenolate mofetil, and calcineurin inhibitors can be considered in selected patients as frontline or salvage therapies. Molecular (recombinant proteins and monoclonal antibodies), cellular (adoptive transfer and antigenic manipulation), and pharmacological (antioxidants, antifibrotics, and antiapoptotic agents) interventions constitute future directions in management. The evolving knowledge of the pathogenic pathways and the advances in technology promise new management algorithms.

Abstract
SCOPE Oxidized tyrosine (O-Tyr) has been widely detected in many consumer protein products. O-Tyr products such as dityrosine (Dityr) and 3-nitrotyrosine (3-NT) are universal biomarkers of protein oxidation and have been demonstrated to be associated with metabolic disorders in biological system. Evaluation of potential intracorporal effects of dietary O-Tyr is important since the mechanism of biological impacts induced by oral oxidized protein products (OPPs) is still limited although we have proved that some dietary OPPs would induce oxidative injury to liver and kidney. METHODS AND RESULTS The present study aimed to investigate the dose-dependent hepatic injury caused by oral O-Tyr in rats. 24-week feeding of O-Tyr enhanced aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities, increased total bilirubin (TBiL) content, and led to oxidative damage in rats liver. Besides, O-Tyr distinctly increased the phosphorylation of p38 and ERK2 MAPKs and enhanced fibrosis-related TGF-β1 and Smad2/3 levels. Higher extracellular matrix (ECM) indexes (ICTP, PIIINP) and histological examination (HE and Masson staining) also supported dose-dependent hepatic fibrosis caused by O-Tyr. CONCLUSION These findings reveal that O-Tyr may induce oxidative damage and hepatic fibrosis via MAPK/TGF-β1 signaling pathway, in which ROS together with malondialdehyde (MDA) and OPPs act as the pivotal mediators.

Abstract
Autoimmune hepatitis lacks an identifiable cause, and its diagnosis requires the exclusion of etiologically defined diseases that resemble it. Insights into its pathogenesis are moving autoimmune hepatitis from an idiopathic to explainable disease, and the goal of this review is to describe the insights that are hastening this transition. Two types of autoimmune hepatitis are justified by serological markers, but they also have distinctive genetic associations (DRB1 and DQB1 genes) and autoantigens. DRB1 alleles are the principal susceptibility factors in white adults, and a six amino acid sequence encoded in the antigen-binding groove of class II molecules of the major histocompatibility complex can influence the selection of autoantigens. Polymorphisms, including variants of SH2B3 and CARD10 genes, may affect immune reactivity and disease severity. The cytochrome mono-oxygenase, CYP2D6, is the autoantigen associated with type 2 autoimmune hepatitis, and it shares homologies with multiple viruses that might promote self-intolerance by molecular mimicry. Chemokines, especially CXCL9 and CXCL10, orchestrate the migration of effector cells to sites of injury and are associated with disease severity. Cells of the innate and adaptive immune responses promote tissue damage, and possible deficiencies in the number and function of regulatory T cells may facilitate the injurious process. Receptor-mediated apoptosis is the principal mechanism of hepatocyte loss, and cell-mediated and antibody-dependent mechanisms of cytotoxicity also contribute. Insights that explain autoimmune hepatitis will allow triggering exogenous antigens to be characterized, risk management to be improved, prognostic indices to be refined, and site-specific therapeutic interventions to emerge.

Abstract
Some patients with autoimmune liver disease have characteristics of cholestasis, as well as of autoimmune hepatitis. Despite the fact that this is a relatively frequent clinical condition seen in referral centers for liver diseases, there is little evidence as regards the clinical management of these syndromes due to their low prevalence and the lack of standardized definitions and diagnostic criteria. This is relevant, given that published studies report that there is a lower therapeutic response and poorer outcome in patients with overlap syndrome than in those presenting solely with autoimmune hepatitis. Whether overlap syndromes are distinct entities or the presence of 2 concurrent diseases is still a subject of debate. They should be suspected in autoimmune hepatitis patients that present with signs of cholestasis, as it is known that overlap behavior tends to be more aggressive, with higher rates of cirrhosis and the need for liver transplantation. Treatment response is also poorer and should be directed at the predominant component. Standardized definitions are necessary so that these syndromes can be studied in controlled clinical trials.
