Abstract
Liver disease is a global health problem that affects the well-being of tens of thousands of people. Dihydroquercetin (DHQ) is a flavonoid compound derived from various plants. Furthermore, DHQ has shown excellent activity in the prevention and treatment of liver injury, such as the inhibition of hepatocellular carcinoma cell proliferation after administration, the normalization of oxidative indices (like SOD, GSH) in this tissue, and the down-regulation of pro-inflammatory molecules (such as IL-6 and TNF-α). DHQ also exerts its therapeutic effects by affecting molecular pathways such as NF-κB and Nrf2. This paper discusses the latest research progress of DHQ in the treatment of various liver diseases (including viral liver injury, drug liver injury, alcoholic liver injury, non-alcoholic liver injury, fatty liver injury, and immune liver injury). It explores how to optimize the application of DHQ to improve its effectiveness in treating liver diseases, which is valuable for preparing potential therapeutic drugs for human liver diseases in conjunction with DHQ.

Autoimmune hepatitis displays distinctively high multi-antennary sialylation on plasma N-glycans compared to other liver diseases. J Transl Med 2024; 22:456. [PMID: 38745252 PMCID: PMC11092172 DOI: 10.1186/s12967-024-05173-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Accepted: 04/05/2024] [Indexed: 05/16/2024] Open
Abstract
BACKGROUND Changes in plasma protein glycosylation are known to functionally affect proteins and to associate with liver diseases, including cirrhosis and hepatocellular carcinoma. Autoimmune hepatitis (AIH) is a liver disease characterized by liver inflammation and raised serum levels of IgG, and is difficult to distinguish from other liver diseases. The aim of this study was to examine plasma and IgG-specific N-glycosylation in AIH and compare it with healthy controls and other liver diseases. METHODS In this cross-sectional cohort study, total plasma N-glycosylation and IgG Fc glycosylation analysis was performed by mass spectrometry for 66 AIH patients, 60 age- and sex-matched healthy controls, 31 primary biliary cholangitis patients, 10 primary sclerosing cholangitis patients, 30 non-alcoholic fatty liver disease patients and 74 patients with viral or alcoholic hepatitis. A total of 121 glycans were quantified per individual. Associations between glycosylation traits and AIH were investigated as compared to healthy controls and other liver diseases. RESULTS Glycan traits bisection (OR: 3.78 [1.88-9.35], p-value: 5.88 × 10- 3), tetraantennary sialylation per galactose (A4GS) (OR: 2.88 [1.75-5.16], p-value: 1.63 × 10- 3), IgG1 galactosylation (OR: 0.35 [0.2-0.58], p-value: 3.47 × 10- 5) and hybrid type glycans (OR: 2.73 [1.67-4.89], p-value: 2.31 × 10- 3) were found as discriminators between AIH and healthy controls. High A4GS differentiated AIH from other liver diseases, while bisection associated with cirrhosis severity. CONCLUSIONS Compared to other liver diseases, AIH shows distinctively high A4GS levels in plasma, with potential implications on glycoprotein function and clearance. Plasma-derived glycosylation has potential to be used as a diagnostic marker for AIH in the future. This may alleviate the need for a liver biopsy at diagnosis. Glycosidic changes should be investigated further in longitudinal studies and may be used for diagnostic and monitoring purposes in the future.

Abstract
The present work aims to evaluate the efficacy of Live Combined Bifidobacterium, Lactobacillus and Enterococcus Capsules (LCBLECs), a probiotic drug containing Bifidobacterium, in the treatment of autoimmune hepatitis (AIH). In this study, a mouse model of experimental autoimmune hepatitis (EAH) was established to investigate the effects of LCBLECs on AIH. The results showed that LCBLECs improved dysbiosis of gut microbiota, reduced liver injury, restored liver function, and maintained Treg/Th17 balance in EAH mice. In addition, LCBLECs restored Treg/Th17 balance in EAH mice by downregulating IL-33 production. Besides, LCBLECs also suppress IL-33 upregulation in EAH mice by inhibiting the TLR2/4 signaling pathway. Furthermore, LCBLECs also mitigated dysbiosis of gut microbiota and enhanced the efficacy of conventional treatment for AIH patients. To sum up, our findings revealed that LCBLECs exerted therapeutic effects on EAH mice by improving Treg/Th17 imbalance in an IL-33-dependent manner via the TLR2/4 signaling pathway and relieved the clinical symptoms of AIH patients, indicating Bifidobacterium supplementation with LCBLECs might be a potential adjuvant therapy for AIH treatment.

Abstract
Rheumatoid arthritis (RA) is a systemic immune-mediated disease that, in addition to the articular involvement, can have extra-articular manifestations. Even though liver damage in RA is not very common, associated autoimmune liver diseases (AILDs) may occur. The most common AILD associated with RA is primary biliary cirrhosis (PBC), followed by autoimmune hepatitis (AIH) and primary sclerosing cholangitis (PSC). There are common underlying mechanisms that play a role in the emergence of autoimmunity and inflammation in both rheumatic and autoimmune liver diseases. Genetic studies have revealed the existence of several common disease-associated genes shared between RA and AILDs, and infectious triggers, particularly those associated with recurrent or complicated urinary tract infections, are also speculated to be potential triggers for these conditions. Moreover, these diseases share common serologic patterns characterized by the presence of specific autoantibodies and hyper-gammaglobulinemia. In this study, we focus on reviewing the association between RA and AILDs regarding the prevalence and possible etiopathogenic link.

Abstract
Aim of the study To investigate whether serum ferritin and vitamin D levels before starting autoimmune hepatitis (AIH) treatment have a role in disease prognosis regarding a therapeutic response. Material and methods The prospective study included 100 children diagnosed with AIH according to simplified criteria for diagnosis of AIH. They attended the Pediatric Hepatology Department, National Liver Institute, Menoufia University. The patients underwent measurement of liver transaminases before starting AIH treatment after 6 months from starting therapy. They underwent liver biopsy before starting treatment for proper diagnosis, grading, and staging; only 25 cases were compliant and underwent liver biopsy before treatment withdrawal. Results Serum ferritin and 25 hydroxy vitamin D levels were significantly higher among those with a complete response (1000-3100 ng/ml, 29-48 ng/ml) than a partial response (550-600 ng/ml, 23-28 ng/ml) and non-response (29.28-92.14, 2.16-8.72) (p < 0.001). Conclusions Our study showed a relation between serum vitamin D before starting AIH treatment, the severity of AIH and response to therapy. This opens a new area of research on the potential use of vitamin D in patients with AIH. Also, hyperferritinemia at the diagnosis can predict the treatment response.

Abstract
BACKGROUND Autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) are two common clinical autoimmune liver diseases, and some patients have both diseases; this feature is called AIH-PBC overlap syndrome. Autoimmune thyroid disease (AITD) is the most frequently overlapping extrahepatic autoimmune disease. Immunoglobulin (IgG) 4-related disease is an autoimmune disease recognized in recent years, characterized by elevated serum IgG4 levels and infiltration of IgG4-positive plasma cells in tissues. CASE SUMMARY A 68-year-old female patient was admitted with a history of right upper quadrant pain, anorexia, and jaundice on physical examination. Laboratory examination revealed elevated liver enzymes, multiple positive autoantibodies associated with liver and thyroid disease, and imaging and biopsy suggestive of pancreatitis, hepatitis, and PBC. A diagnosis was made of a rare and complex overlap syndrome of AIH, PBC, AITD, and IgG4-related disease. Laboratory features improved on treatment with ursodeoxycholic acid, methylprednisolone, and azathioprine. CONCLUSION This case highlights the importance of screening patients with autoimmune diseases for related conditions.

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.

Abstract
Hepatocellular carcinoma (HCC) in a non-fibrotic liver (F0) is considered to be rare, and there is a marked paucity of studies in the literature on this HCC type. A review of the literature shows some important clinical and tumor characteristics: (a) it occurs mainly in young female and elder male patients; (b) clinically, under normal hepatic function, alpha-fetoprotein level is often normal, and there are no risk factors; (c) associated with metabolic disease; (d) macroscopically, single large lesions are noted; and (e) microscopically, the lesions are well-differentiated and encapsulated. Radiological imaging results are straightforward, showing arterial hyperenhancement and later wash-out. The combined use of B-mode and contrast-enhanced (CE) ultrasound (US) is the most reliable and cost-effective diagnostic method. Few peri-and post-operative complications are noted and 5-year survival is not inferior to patients with HCC on fibrosis liver despite the lesion's large size. Most clinicians believe that HCC is unlikely to occur if patients have no symptoms and normal hepatic function. Although detailed clinical data are very limited, we expect that this review will help to improve the clinical management of HCC in non-fibrotic livers.

Abstract
Background and Aim High autoimmune hepatitis (AIH) and overlap syndrome (OS) prevalence have been previously documented among Alaska Native people. The purpose of this project is to report changes in AIH/OS prevalence over time, clinical characteristics, and factors associated with biochemical remission. Methods We reviewed medical records for Alaska Native/American Indian (AN/AI) patients diagnosed with AIH/OS between 1984 and 2021. Point prevalence was calculated based on AIH/OS patients alive at the end of 2021 and at 5-year intervals from July 1, 2000, to July 1, 2020. Results We identified 189 AN/AI persons diagnosed with AIH or OS (157 AIH, 32 OS). Of these 189, 137 were alive at the end of 2021 for a point prevalence of 91.2 per 100 000 (95% confidence interval [CI]: 77.2-107.8)-75.9 (95% CI: 63.2-91.2) for AIH and 15.3 (95% CI: 10.2-23.0) for OS. Prevalence for both AIH and OS has risen steadily since 2000. Eighty-nine consented participants (62.7%) achieved biochemical remission with a median time from diagnosis to start of remission of 1.9 years (IQR 0.5-5.0 years). Consented patients with fatty liver were less likely to achieve remission, but their time to remission was shorter than for patients without fatty liver. Conclusion The AN/AI population in Alaska continues to have the highest reported prevalence of AIH/OS in the world, with prevalence rising steadily since 2000. High reported AIH/OS prevalence is likely due in part to strong referral networks for liver disease. Detection and treatment can lead to biochemical remission and improved health outcomes.

Antibodies against multiple post-translationally modified proteins aid in diagnosis of autoimmune hepatitis and associate with complete biochemical response to treatment. Front Med (Lausanne) 2023; 10:1195747.

Abstract
Background (Auto)immune mediated and cholestatic liver disease (AILD) includes autoimmune hepatitis (AIH), primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC). Especially AIH is characterized by the presence of autoantibodies and elevated serum immunoglobulins. In rheumatoid arthritis, autoantibodies against post-translational modifications (PTMs) such as citrullination (Cit) and carbamylation (CarP) are used as diagnostic and prognostic markers, respectively. We studied the presence of six anti-PTM antibodies in patients with the three AILDs and non-AILD. Methods Antibodies against six PTMs (malondialdehyde-acetaldehyde adducts (MAA), advanced glycation end-products (AGE), CarP, acetylation (AL), Cit, and nitration (NT)) were tested in sera of patients with AILD (n = 106), non-AILD (n = 101) and compared with healthy controls (HC) (n = 100). Levels and positivity were correlated with clinical and biochemical features in a well-defined cohort of untreated AIH patients. Results Anti-PTM antibodies were more often detectable in sera from AILD patients compared with HCs (anti-MAA: 67.9% vs. 2.0%, anti-AGE: 36.8% vs. 4.0%, anti-CarP: 47.2% vs. 5.0% and anti-AL: 18.9% vs. 5.0%). In untreated AIH, time to complete biochemical response (CBR) was associated with anti-MAA, anti-AGE, anti-CarP and anti-AL antibodies. Significantly more patients with at least three anti-PTM antibodies attained CBR at 12 months of treatment (13 vs. 3 p = 0.01). Conclusion Anti-PTM antibodies are frequently present in AILD. The presence of anti-MAA, anti-AGE and anti-CarP antibodies correlates with the presence of AIH within this cohort. In AIH, harboring at least three anti-PTM antibody responses is positively associated with CBR. Determination of anti-PTM antibodies in liver disease may have diagnostic and prognostic value.

Abstract
Background A hepatic adverse event (HAE) is defined as a liver injury that occurs following immune checkpoint inhibitor (ICI) administration in oncology Patients. Immune-mediated hepatotoxicity (IMH) is a type of HAE directly caused by ICI and is associated with immune system hyperactivation. HAE incidence varies across different clinical studies. This study aimed to explore the risk factors of HAE and establish a personalized IMH treatment strategy. Methods Randomized controlled trials (RCTs) on ICIs and case reports related to IMH were collected and summarized separately. Meta-analysis was performed using Review Manager (version 5.0), whereas correlation analysis and linear regression were performed using SPSS (version 24.0) to evaluate any correlations between the two variables. Results Overall, 36 RCTs containing 18,515 patients and 39 case reports met our inclusion criteria. The ICI administration increased the HAE risk (risk ratio [RR] = 1.40) as well as severe HAE (RR = 2.55). The overall HAE incidence and severe incidence were about 15.3% and 4.3%, respectively. Cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitors have a higher incidence of HAE than programmed cell death protein 1 (PD-1) and programmed death-ligand 1 (PD-L1) inhibitors. Finally, we found a positive correlation between the onset time of IMH and the recovery time of liver injury. Conclusions ICI administration increased the incidence risk of HAE, especially in patients treated with CTLA-4 inhibitors. Regarding IMH treatment, the glucocorticoid dosage must be individually reduced according to the severity and onset time of HAE.

Abstract
Autoimmune hepatitis is a rare form of chronic liver inflammation that begins as acute hepatitis and progresses to chronic liver disease. It presents with varied clinical features from acute hepatitis to chronic liver diseases like chronic viral hepatitis and alcoholic liver disease, making it difficult to diagnose in the absence of a high index of suspicion and adequate laboratory support. Autoimmune hepatitis is divided into two categories autoimmune hepatitis-1 and autoimmune hepatitis-2 based on the antibodies involved. We discuss the case of a 37-year-old woman who developed autoimmune hepatitis-1, with swelling and epigastric pain. These symptoms later progressed to liver cirrhosis leading to the death of the patient. Autoimmune hepatitis is extremely sensitive to immunosuppressive medication, it is necessary to maintain a high suspicion index for the disease because a prompt diagnosis can be an integral step toward a better prognosis of the disease. Keywords autoimmune hepatitis; case reports; chronic hepatitis; liver cirrhosis.

Abstract
Autoimmune hepatitis (AIH) is an inflammatory condition of the liver that is characterized by high titers of certain autoantibodies in the serum. As in other chronic inflammatory conditions, the transferrin saturation in patients with AIH is typically low. However, in rare instances, AIH has been reported to be associated with elevated transferrin saturation secondary to heterozygous HFE gene (H63D) mutation. This report describes one such case in which the patient had characteristic histopathologic findings of AIH but was also found to have iron overload and heterozygous H63D mutation on genetic testing, leading to the initial dual differential diagnosis of AIH and hemochromatosis, which highlighted the further need of obtaining a liver biopsy.

Abstract
BACKGROUND & AIMS Biochemical remission, important treatment goal in autoimmune hepatitis (AIH), has been associated with better long-term survival. 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
Antibiotics are among the essential veterinary medicine compounds associated with animal feed and food animal production. The use of antibiotics for the treatment of bacterial infections is almost unavoidable, with less need to demonstrate their importance. Although banned as a growth factor for a few years, their use in animals can add residues in foodstuffs, presenting several environmental, technological, animal health, and consumer health risks. With regard to human health risks, antibiotic residues induce and accelerate antibiotic resistance development, promote the transfer of antibiotic-resistant bacteria to humans, cause allergies (penicillin), and induce other severe pathologies, such as cancers (sulfamethazine, oxytetracycline, and furazolidone), anaphylactic shock, nephropathy (gentamicin), bone marrow toxicity, mutagenic effects, and reproductive disorders (chloramphenicol). Antibiotic resistance, which has excessively increased over the years, is one of the adverse consequences of this phenomenon, constituting a severe public health issue, thus requiring the regulation of antibiotics in all areas, including animal breeding. This review discusses the common use of antibiotics in agriculture and antibiotic residues in food/feed. In-depth, we discussed the detection techniques of antibiotic residues, potential consequences on the environment and animal health, the technological transformation processes and impacts on consumer health, and recommendations to mitigate this situation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The dried roots and rhizomes of Cynanchum atratum Bunge is named 'Baiwei' according to traditional Chinese medicine theory. It is also named Cynanchi atrati Radix in Chinese Pharmacopoeia. Cynanchi atrati Radix is famous for its medicinal value of clearing away heat, relieving drenching, detoxifying and treating abscesses. It was commonly used in some Asian countries for the treatment of fever, vasoconstrictive syncope, lymphangitis and other diseases, obviously due to the effect of C21 steroidal glycosides. THE AIM OF THE REVIEW The review concentrates on the botany, ethnopharmacology, phytochemistry, pharmacology and toxicology of Cynanchum atratum. We also discuss expectations for prospective research and implementation of this herb. MATERIALS AND METHODS Relevant information about C. atratum was gained from ancient books and records, Doctoral and master's Theses, Science Direct, Pubmed, Wiley, CNKI, WanFang DATA, Google Scholar and other domestic and foreign literature. Some electronic databases have been included. RESULTS As a member of the Apocynaceae family, C. atratum possesses its up-and-coming biological characteristics. It is widely reported for treating of postpartum fatigue, vomiting, urine drops, nephritis, urinary tract infection, edema, bronchitis and rheumatic low back pain. By now, over 100 compounds have been identified from C. atratum, including C21 steroidal glycosides, acetophenones, alkaloids, volatile oil and other ingredients. Activities such as anti-inflammatory, anti-tumor, anti-virus, antibacterial, anti-forgetful and others have been corroborated in vivo and in vitro. In addition, many of the active ingredients, such as Cynatratoside A, Cynanversicoside A, B, D, G, p-hydroxyacetophenone, 2,4-dihydroxyacetophenone and some volatile oils have been used as quality markers. CONCLUSION All kinds of research conducted on C.atratum, especially in field of ethnopharmacological use, phytochemicals and pharmacology have been reviewed. The herb has been used over the years in treating nephritis, urinary tract infection, bronchitis and rheumatic lumbocrural pain. Many studies have been carried out to identify compounds that play a leading role in drug activity. However, the mechanism of drug therapy remains unclear. The evidence used to prove the quality standard of medicinal materials is obviously inadequate. Besides, safety evaluation is necessary for clinical medication. Similarly, the separation of steroidal saponins and the development of new drugs will also need further discussion.

Abstract
BACKGROUND No prognostic score is currently available for long-term survival in autoimmune hepatitis (AIH) patients. OBJECTIVE The aim of this study was to develop and validate such a prognostic score for AIH patients at diagnosis. METHODS The prognostic score was developed using uni- & multivariate Cox regression in a 4-center Dutch cohort and validated in an independent 6-center Belgian cohort. RESULTS In the derivation cohort of 396 patients 19 liver transplantations (LTs) and 51 deaths occurred (median follow-up 118 months; interquartile range 60-202 months). In multivariate analysis age (hazard ratio [HR] 1.045; p < 0.001), non-caucasian ethnicity (HR 1.897; p = 0.045), cirrhosis (HR 3.266; p < 0.001) and alanine aminotransferase level (HR 0.725; p = 0.003) were significant independent predictors for mortality or LT (C-statistic 0.827; 95% CI 0.790-0.864). In the validation cohort of 408 patients death or LT occurred in 78 patients during a median follow-up of 74 months (interquartile range: 25-142 months). Predicted 5-year event rate did not differ from observed event rate (high risk group 21.5% vs. 15.7% (95% CI: 6.3%-24.2%); moderate risk group 5.8% versus 4.3% (95% CI: 0.0%-9.1%); low risk group 1.9% versus 5.4% (95% CI: 0.0%-11.4%); C-statistic 0.744 [95% CI 0.644-0.844]). CONCLUSIONS A Dutch-Belgian prognostic score for long-term transplant-free survival in AIH patients at diagnosis was developed and validated.

Non-invasive assessment of liver fibrosis in autoimmune hepatitis: Diagnostic value of liver magnetic resonance parametric mapping including extracellular volume fraction. Abdom Radiol (NY) 2021; 46:2458-2466.

Abstract
Purpose Autoimmune hepatitis (AIH) is an immune-mediated chronic liver disease that leads to severe fibrosis and cirrhosis. The aim of this study was to determine the diagnostic value of T1 and T2 mapping as well as extracellular volume fraction (ECV) for non-invasive assessment of liver fibrosis in AIH patients. Methods In this prospective study, 27 patients (age range: 19–77 years) with AIH underwent liver MRI. T1 and T2 relaxation times as well as ECV were quantified by mapping techniques. The presence of significant fibrosis (≥ F2) was defined as magnetic resonance elastography (MRE)-based liver stiffness ≥ 3.66 kPa. MRE was used as reference standard, against which the diagnostic performance of MRI-derived mapping parameters was tested. Diagnostic performance was compared by utilizing receiver-operating characteristic (ROC) analysis. Results MRE-based liver stiffness correlated with both, hepatic native T1 (r = 0.69; P < 0.001) as well as ECV (r = 0.80; P < 0.001). For the assessment of significant fibrosis, ECV yielded a sensitivity of 85.7% (95% confidence interval (CI): 60.1–96.0%) and a specificity of 84.6% (CI 60.1–96.0%); hepatic native T1 yielded a sensitivity of 85.7% (CI 60.1–96.0%); and a specificity of 76.9% (CI 49.7–91.8%). Diagnostic performance of hepatic ECV (area under the curve (AUC): 0.885), native hepatic T1 (AUC: 0.846) for assessment of significant fibrosis was similar compared to clinical fibrosis scores (APRI (AUC: 0.852), FIB-4 (AUC: 0.758), and AAR (0.654) (P > 0.05 for each comparison)). Conclusion Quantitative mapping parameters such as T1 and ECV can identify significant fibrosis in AIH patients. Future studies are needed to explore the value of parametric mapping for the evaluation of different disease stages.

Next-Generation Immunosequencing Reveals Pathological T-Cell Architecture in Autoimmune Hepatitis. Hepatology 2021; 73:1436-1448.

Abstract
BACKGROUND AND AIMS Autoimmune hepatitis (AIH) is a chronic liver disease that regularly relapses when immunosuppression is tapered. It is thought to be driven by T-cells, whereas the etiologic impact of an apparently deregulated B lineage system, as evidenced by hypergammaglobulinemia and autoantibodies, remains elusive. We set out to investigate T and B cell repertoires supporting chronic inflammation in AIH. APPROACH AND RESULTS T and B cell receptor (TCR/BCR) and human leukocyte antigen (HLA) next-generation immunosequencing were used to record immune signatures from a cohort of 60 patients with AIH and disease controls. Blood and liver B lineage immune metrics were not indicative of a dominant directional antigen selection apart from a slight skewing of IGHV-J genes. More importantly, we found strong AIH-specific TRBV-J skewing not attributable to the HLA-DRB1 specificities of the cohort. This TCR repertoire bias was generated as a result of peripheral T cell (de)selection and persisted in disease remission. Using a clustering algorithm according to antigenic specificity, we identified liver TCR clusters that were shared between patients with AIH but were absent or deselected in patients with other liver pathologies. CONCLUSIONS Patients with AIH show profound and persisting T-cell architectural changes that may explain high relapse rates after tapering immunosuppression. Liver T-cell clusters shared between patients may mediate liver damage and warrant further study.

Abstract
Presentation of autoimmune hepatitis (AIH) can differ from nonacute to acute autoimmune hepatitis (A-AIH) with jaundice and acute severe autoimmune hepatitis (AS-AIH) with jaundice and coagulopathy. The aim of the study was to evaluate the short-term prognosis of different presentations of AIH and the influence of liver function improvement on short-term prognosis. In this single-center retrospective cohort study, AIH patients with repeatedly tested liver function at diagnosis and during at least 1 year of follow-up were included. A-AIH was defined as bilirubin >45 µmol and international normalized ratio (INR) <1.5. AS-AIH was defined as bilirubin level >45 µmol/L and INR ≥1.5. Of the 81 included patients, 17 (21%) presented with A-AIH, and 14 (17%) presented with AS-AIH. After the start of immunosuppressive therapy, bilirubin, albumin, and INR normalized in 70%, 77%, and 69%, respectively, in a median of 2.6 months, 3 months, and 4 weeks, respectively, in patients with A-AIH and AS-AIH. Liver transplantation (LT)-free survival rate was 100% in nonacute AIH, 94% in A-AIH, and 57% in AS-AIH at 12 months after diagnosis. An increase of INR or bilirubin at 2 weeks was the best predictive factor for the need of LT within 12 months with a Youden's index of 0.85. A-AIH was present in 21%, and AS-AIH was present in 17% of AIH patients. In the majority of patients, bilirubin, albumin, and INR normalized in the first months of treatment. Deterioration of liver function after 2 weeks of treatment should lead to rapid evaluation for LT and consideration of second-line medication.

Abstract
Autoimmune hepatitis (AIH) is recognized as a serious disease in which the body’s immune system attacks liver cells so untreated patients may consequently suffer from liver cirrhosis, hepatocellular carcinoma (HCC) and liver failure. The role of viral infection may be involved in AIH. Presence of anti-HBc alone is a predictive signal of potential OBI. Thus, this study was conducted to evaluate the rate OBI among the patients with AIH.

The role of complement activation in autoimmune liver disease. Autoimmun Rev 2020; 19:102534.

Abstract
INTRODUCTION The complement system, an essential part of the innate immune system, is involved in various autoimmune diseases. Activation of the complement system by autoantibodies results in immune activation and tissue damage. At the moment little is known about the role of the complement system in autoimmune liver disease, including primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH). Since inhibition of the complement system is currently being tested in several autoimmune diseases as a therapeutic option, its role in autoimmune liver disease requires further clarification. METHODS A review of the literature was performed on studies investigating complement activation in PBC, PSC and AIH. Since data on AIH were lacking immunohistochemical staining for IgG, C1q, C3d, C4d and C5b9 was performed on liver tissue of nine AIH patients, two healthy controls and one positive control (acute liver failure caused by paracetamol intoxication). RESULTS Immunohistochemical analysis in AIH revealed increased production of C3 and C4 by hepatocytes. Despite a strong staining for IgG in the immune infiltrate in AIH, C3d, C4d and C5b9 deposition was only present in one AIH patient and the deposition was restricted to the interface between portal tracts and liver parenchyma. No deposition was found in all other AIH patients or healthy controls. Literature review showed raised plasma C3 and C4 levels in AIH, PBC and PSC patients compared to healthy controls. For PBC and PSC no complement depositions at the bile ducts were reported. CONCLUSION AND DISCUSSION Although complement is involved in various autoimmune diseases, the role of complement in autoimmune liver disease seems limited. Therefore it is unlikely that complement inhibition will become a novel treatment option for these diseases.

Abstract
BACKGROUND & AIMS Population-based studies on the epidemiology of autoimmune hepatitis (AIH) are scarce. Drug-induced AIH (DIAIH) is increasingly recognized in association with immunomodulatory therapy. We aimed to determine the incidence, prevalence and natural history of AIH in a population-based setting. METHODS We collected data of new diagnosis of AIH in Iceland from 2006 to 2015. Cases were identified through search of diagnostic codes and text search for AIH within electronical medical records of all hospitals in Iceland and through records of smooth muscle antibodies (SMA) test results by the only laboratory in the country analyzing SMA. Patients were included in the final analysis if they received the clinical diagnosis of AIH or were started on immunosuppressive therapy. RESULTS The mean annual incidence of AIH in Iceland was 2.2 cases per 100 000 inhabitants. Point prevalence on 31 December 2015 was 27/100 000. The median age at diagnosis was 56 years and 86% of patients were of female gender. DIAIH was suspected in 13 of 71 patients (18%) of which eight cases were related to infliximab. Immunosuppressive treatment was started in all but two patients. At the end of follow-up (median 4.8 years) 66 of 71 (93%) patients were alive. CONCLUSION The incidence and prevalence rates of AIH in Iceland are the highest reported so far in a population-based setting. Higher incidence can partly be explained by the increasing use of biological drugs. Immunosuppressive therapy was very effective in achieving remission and prognosis was favorable.

Abstract
BACKGROUND Autoimmune hepatitis requires long-term therapy, and systemic corticosteroids are the backbone of therapeutic management. Prolonged use of corticosteroids may lead to adverse events but data from long-term studies are mainly derived from studies in rheumatic diseases. AIM To assess cataract, diabetes and fractures in relation to corticosteroid doses in the long-term maintenance treatment of patients with autoimmune hepatitis. METHODS We retrospectively collected data on 476 patients (77% women) with an established diagnosis of autoimmune hepatitis. Binary logistic regression with a generalised estimating equation was used to analyse the association between current corticosteroid use and the incidence of cataract, diabetes and fractures with onset after autoimmune hepatitis diagnosis. We corrected for sex, age, cirrhosis at diagnosis and predniso(lo)ne use in the prior 3 years to account for possible ongoing effects. RESULTS A total of 6634 years, with a median of 13 (range 1-40) per patient were recorded. The median age at diagnosis was 44 years (range 2-88). Adverse events were documented in 120 (25%) patients. Low-dose predniso(lo)ne (0.1-5.0 mg/d) increased the odds of fractures whereas higher doses (>5.0 mg/d) increased the odds of cataracts and diabetes. Budesonide increased the odds of cataract and fractures; this effect was independent of predniso(lo)ne use in the prior 1, 2 or 3 years. CONCLUSIONS Even low doses of corticosteroids frequently lead to substantial adverse events refuting the assumption that adverse events are prevented by administering low doses.

Abstract
INTRODUCTION Liver biopsy is a well-known method for the diagnosis and evaluation of chronic diffuse liver diseases, especially among patients with "hepatopathy of unknown origin". MATERIAL AND METHODS In the years 2014-2015 we performed 259 liver biopsies in 28 patients (22 females, 6 males, aged 18-65 years, mean: 45 years) with an initial diagnosis of "hepatopathy of unknown origin". The liver biopsies of these 28 patients were revised by two independent pathologists. RESULTS Histopathological features of autoimmune conditions were found in 11 cases, steatohepatitis with/without Mallory bodies in 7, simple steatosis without inflammation in 2 cases. In the other 8 cases the histopathological features were non-specific but pointed to vanishing bile duct syndrome, hemochromatosis, acute inflammation or fibrosis without inflammation. Surprisingly, only mild fibrosis without inflammatory infiltrates was present in one patient with a high titer of antinuclear antibodies (ANA > 1 : 3200). Mild cholestasis with bilirubinostasis was found in 4 cases. One patient had prominent lobular iron deposits and is now under observation for hemochromatosis. Vanishing bile duct syndrome as ductopenia without any signs of inflammation was found in one patient with suspicion of primary biliary cirrhosis. In one liver biopsy specimen we found normal liver architecture without inflammation or steatosis in a patient with elevated ALT and GGT, negative for viral antibodies and autoantibodies. CONCLUSIONS Liver biopsy - despite the increasing access to new, non-invasive methods - remains a useful method in the differential diagnosis of liver diseases.

Abstract
Background and aims Liver cancer is one of the most common cause of deaths from cancer. Hepatocellular carcinoma (HCC) was reported at a frequency of 7% of patients with autoimmune hepatitis (AIH) - related cirrhosis in 1988. We aimed to provide a systematic literature review on the frequency of HCC in patients with AIH, after the discovery of hepatitis C virus (HCV), in order to avoid any possible confounding etiology. Methods A literature search of the PubMed database between 1989–2016 was performed, using the relevant keywords “hepatocellular carcinoma” and “autoimmune hepatitis”. We followed the PRISMA statement guidelines during the preparation of this review. Results Eleven studies (n=8,460 patients with AIH) were retained for the final analysis. HCC was diagnosed in 0–12.3% of the AIH patients included in these studies. The overall occurrence of HCC in patients with AIH was estimated in two studies, at 5.1% and 6.2%, respectively. In patients with AIH and cirrhosis, the percentage of HCC varied between 0.2%–12.3%. The proportion of HCC in patients with AIH without cirrhosis was estimated at 1.03%. The percentage of cirrhosis in AIH patients varied from 18.7% to 83.3% in Japan, and from 12% to 50.2% in the other areas. The mean follow-up of the patients with AIH was of 10 years. Conclusions The development of HCC in patients with AIH appeared to be similar before and after the discovery of HCV, and it was mainly associated to cirrhosis. The number of patients developing cirrhosis in relation with AIH was impressive. The long evolution of AIH to cirrhosis and, eventually, to HCC, has been be suggested.

Abstract
Cynatratoside A (CyA) is a C21 Steroidal glycoside with pregnane skeleton isolated from the root of Cynanchum atratum Bunge (Asclepiadaceae). This study aimed to investigate the effects of CyA on concanavalin A (Con A)-induced autoimmune hepatitis (AIH) and the underlying mechanism. CyA was orally administered to mice at 10 and 40 mg/kg 8 h before and 1 h after Con A treatment. The effects of CyA on Con A-induced spleen and liver in mice were assessed via histopathological changes, T lymphocyte amounts and the expressions of IL-1β and ICAM-1. Con A-induced L-02 hepatocytes were used to evaluate whether CyA (0.1–10 μM) can directly protect hepatocytes from cytotoxicity and the possible mechanism. The results revealed that CyA treatment could significantly improve the histopathological changes of spleen and liver, reduce the proliferation of splenic T lymphocytes, and decrease the expressions of IL-1β and ICAM-1 in liver. The experiment in vitro showed that CyA inhibited Con A-induced hepatotoxicity in a concentration-dependent manner. CyA (10 μM) significantly increased/decreased the expression of Bcl-2/Bax and reduced the levels of cleaved caspases-9 and -3. Our study demonstrated for the first time that CyA has a significant protective effect on Con A-induced AIH by inhibiting the activation and adhesion of T lymphocytes and blocking hepatocyte apoptosis.

Abstract
BACKGROUND Azathioprine (AZA) and mercaptopurine (MP) are the cornerstone of steroid-sparing strategies in autoimmune hepatitis (AIH). Up to 20% of patients do not tolerate or respond to these regimens. AIM To evaluate retrospectively the tolerability and efficacy of tioguanine (thioguanine) (TG) therapy in selected patients with AIH and AIH variant syndromes. METHODS Records of 52 patients who received TG therapy were retrieved from nine hospitals in the Netherlands. Indications for TG treatment were intolerable side effects on AZA or MP (n = 38), insufficient response (n = 11) or first-line treatment (n = 3). Treatment efficacy was defined as normalisation of serum aminotransferases and serum immunoglobulin G. RESULTS No serious adverse events occurred in patients treated with TG during a median follow-up of 18 months (range 1-194). Treatment was well tolerated in 41 patients (79%), whereas four had tolerable (8%) and seven (13%) intolerable side effects. Thirty-eight patients were treated with TG after intolerable side effects on AZA or MP; 29 patients continued TG therapy of whom 24 (83%) achieved complete biochemical remission, four (14%) had incomplete and one (3%) had no response; nine discontinued treatment. Seven of 11 patients with insufficient response to AZA or MP were responsive to TG, three with complete and four with incomplete biochemical remission; four discontinued due to intolerance (n = 2) and non-response (n = 2). TG was effective in all AIH patients as first-line maintenance treatment. CONCLUSION In our retrospective review of TG therapy in selected patients with AIH or AIH variants who previously failed on AZA or MP, TG appeared tolerable with biochemical efficacy.

Randomized, Double-Blind, Placebo-Controlled, Single Ascending Dose Trial of Synthetic Preimplantation Factor in Autoimmune Hepatitis. Hepatol Commun 2018; 2:1235-1246. [PMID: 30411073 PMCID: PMC6218676 DOI: 10.1002/hep4.1239] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2018] [Accepted: 07/09/2018] [Indexed: 12/16/2022] Open
Abstract
Preimplantation factor (PIF) is an evolutionary conserved peptide secreted by viable embryos which promotes maternal tolerance without immune suppression. Synthetic PIF (sPIF) replicates native peptide activity. The aim of this study was to conduct the first‐in‐human trial of the safety, tolerability, and pharmacokinetics of sPIF in patients with autoimmune hepatitis (AIH). We performed a randomized, double‐blind, placebo‐controlled, prospective phase I clinical trial. Patients were adults with documented AIH with compensated chronic liver disease. Diagnosis of AIH was confirmed by either a pretreatment International Criteria for the Diagnosis of AIH score of 15 or more, or a posttreatment score of 17 or more. Patients were divided into three dosing cohorts (0.1, 0.5, or 1.0 mg/kg) of 6 patients in each group. Three patients in each group had normal liver tests and 3 patients had abnormal liver tests. They were randomized to receive a single, subcutaneous dose of either sPIF or a matching placebo. Eighteen patients were enrolled, and all successfully completed the trial. There were no clinically significant adverse events and all doses were well tolerated. Ascending doses of sPIF produced a linear increase in the respective serum levels with a half‐life of 90 minutes. There were no grade 2, 3 or 4 laboratory abnormalities. No patient developed detectable anti‐sPIF antibodies. Conclusion: This first‐in‐human trial of the safety and pharmacokinetics of sPIF (a novel biologic immune modulatory agent) demonstrated both excellent safety and tolerability. The data support further studies of multiple ascending doses of sPIF in autoimmune hepatitis and potentially other autoimmune disorders.

Guirguis J, Alonso Y, Lopez R, Carey W. Well-controlled autoimmune hepatitis treatment withdrawal may be safely accomplished without liver-biopsy guidance. Gastroenterol Rep (Oxf) 2018; 6:284-290. [PMID: 30430017 PMCID: PMC6225821 DOI: 10.1093/gastro/goy020] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2018] [Revised: 02/26/2018] [Accepted: 05/08/2018] [Indexed: 12/25/2022] Open
Abstract
Background Autoimmune hepatitis may flare up after treatment withdrawal, especially in those who had not achieved histological remission but had normal liver enzymes. The European Association for the Study of the Liver (EASL) and the American Association for the Study of Liver Disease (AASLD) Guidelines recommend performing liver biopsy before treatment withdrawal. The aim of the study is to define the outcome of treatment withdrawal in adults with well-controlled disease for 2 years with and without liver-biopsy guidance. Methods A retrospective observational study was conducted on biopsy-proven autoimmune hepatitis patients who were treated for 2 years and with persistently normal aspartate aminotransferase (AST) and alanine aminotransferase (ALT) or nearly so for 6 months prior to treatment withdrawal. Exclusions were: juvenile onset autoimmune hepatitis and prior treatment or use of agents other than corticosteroids and azathioprine. The primary endpoint was to define freedom from flare-ups for 1 year after treatment withdrawal. Results Thirty-four consecutive subjects meeting study criteria were identified. Treatment withdrawal was accomplished in 24 subjects without liver-biopsy guidance and 10 had pre-treatment withdrawal liver biopsy. Demographics, immunosuppressive usage, pre-treatment cirrhosis and pre-treatment liver enzymes were similar between the two groups, and 25% had an enzyme flare-up within 12 months after treatment withdrawal, which was similar in the two groups (20.8 vs 30.0%, P = 0.57). Conclusions Adults with autoimmune hepatitis and excellent response to therapy for 2 years are candidates for treatment withdrawal without the need for liver biopsy.

Abstract
BACKGROUND Single nucleotide polymorphisms of the IL10 gene have been linked to the occurrence of autoimmune liver disease. METHODS We performed a meta-analysis to assess the association between three IL10 promoter polymorphisms (rs1800896, rs1800871, and rs1800872) and the risk of autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis. RESULTS In total, 1420 articles were initially identified through database retrieval. After screening, seven eligible articles were ultimately included in the meta-analysis. A fixed-effect model was used for all Mantel-Haenszel statistics due to the absence of large between-study heterogeneity (all I2 < 50%, p > 0.1). No association between any of the studied polymorphisms and risk of autoimmune liver disease was detected in the allele, homozygote, heterozygote, dominant, recessive, or carrier genetic models (passociation > 0.05). Potential publication bias was excluded using Begg's and Egger's tests. Similar negative results were observed in subgroup analyses and in an analysis of the three haplotypes of rs1800896/rs1800871/rs1800872 (G/C/C, A/C/C, and A/T/A). CONCLUSION Our meta-analysis strongly suggests that the IL10 rs1800896, rs1800871, and rs1800872 polymorphisms are not associated with the risk of autoimmune liver disease.

Abstract
Autoimmune hepatitis (AIH) is a rare cause of chronic liver disease (CLD). It presents with varied clinical features from acute hepatitis to CLDs like chronic viral hepatitis and alcoholic liver disease, making it difficult to diagnose in the absence of a high index of suspicion and adequate laboratory support. Autoantibody-mediated hepatocyte injury is the major feature of AIH. We present a 44 year old woman with recurrent jaundice, ascites, splenomegaly, coagulopathy, negative chronic viral hepatitis screening, elevated IgG and positive anti-smooth muscle antibody. The patient responded well to immunosuppressive therapy. This report brings to the fore the need for physicians to maintain a high index of suspicion and thoroughly evaluate all CLD cases of seemingly 'unknown' etiology for AIH in order to prevent progression to end-stageliver- disease, since the disease is highly amenable to immunosuppressive therapy.
