External validation of the IAIHG autoimmune hepatitis response criteria in a multicentric real-world cohort. JHEP Rep 2024; 6:101149. [PMID: 39247177 PMCID: PMC11379665 DOI: 10.1016/j.jhepr.2024.101149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 05/21/2024] [Accepted: 06/18/2024] [Indexed: 09/10/2024] Open
Abstract
Background & Aims The goal of treatment in autoimmune hepatitis (AIH) is induction of remission to prevent the development of liver fibrosis, cirrhosis, and its related complications. Various definitions of treatment response and remission have been used. The International Autoimmune Hepatitis Group (IAIHG) recently defined consensus criteria for treatment response. We aimed to validate the IAIHG response criteria in our cohort and establish correlations with survival endpoints. Methods We performed a retrospective, multicentric cohort study in one tertiary and seven secondary care centres in Belgium. Eligible patients were at least 18 years of age at data collection and were diagnosed with AIH by a simplified IAIHG score of ≥6. Complete biochemical response (CBR) was defined according to the IAIHG consensus criteria as normalisation of transaminases and serum IgG within the first 6 months of treatment. The primary endpoint was liver-related survival - defined as freedom from liver-related death or liver transplantation. Secondary endpoints were overall mortality and transplant-free survival. Outcomes were compared between patients attaining CBR and those with insufficient response. Results Biochemical response status could be determined in 200 patients with AIH: CBR was achieved in 128 (64.0%) individuals. Patients not achieving CBR more frequently presented with cirrhosis on initial histology (22.2% vs. 10.9%, p = 0.036). Liver-related mortality or liver transplantation as a primary outcome occurred in 26 patients (13.0%). Patients achieving CBR exhibited superior liver-related (hazard ratio 0.118; 95% CI 0.052-0.267; p <0.0001) and overall (hazard ratio 0.253; 95% CI 0.111-0.572; p = 0.0003) survival. Conclusions We externally validated the IAIHG consensus criteria for CBR and confirmed their correlation with survival endpoints in a multicentric, real-world cohort. Patients with AIH achieving CBR as an intermediate endpoint have significantly superior liver-related and overall survival. Impacts and Implications Corticosteroids remain the cornerstone of treatment to induce remission of disease activity in autoimmune hepatitis (AIH), and the majority of patients require long-term corticosteroid treatment to achieve sustained remission. Definitions of response to treatment have varied over the years, and consistently used intermediate endpoints are needed to facilitate advancements in non-corticosteroid treatment for autoimmune hepatitis. The International Autoimmune Hepatitis Group (IAIHG) defined consensus criteria on endpoints in the treatment of AIH, for which further external validation is needed. Here, we demonstrate the usefulness of the IAIHG consensus criteria and corroborate their correlation to primary endpoints, such as liver-related survival and native liver survival in a multicentric, real-world setting. The design of future studies can rely on the IAIHG consensus criteria as intermediate endpoints.

Abstract
Acute-on-chronic liver failure (ACLF) is a global health problem. Little scientific evidence exists on its prevalence in autoimmune hepatitis. Treatment response and mortality outcomes have also been reported differently. The study was conducted to estimate the overall prevalence of ACLF among patients with autoimmune hepatitis (AIH) and determine the associated treatment response and mortality. We scrutinized wide literature in Scopus, PubMed, Embase, Web of Science, and Cochrane, and assessed published articles completely, studies performed and reported from around the globe, until December 07, 2023, according to the PROSPERO registered protocol (CRD42023412176). Studies (retrospective and prospective cohort study type) that stated the ACLF development among established AIH cases were considered. Features of the study, duration of follow-up, and numeric patient information were retrieved from the studies included. The research paper quality was checked for risk of bias. Random effect meta-analysis with metaregression and subsection scrutinies were performed with R. The main outcome was the collective prevalence of ACLF in the AIH patients, whereas treatment response and mortality in AIH-associated ACLF were secondary outcomes. Six studies were involved with confirmed diagnoses in 985 AIH patients for the data synthesis. The pooled prevalence of ACLF in the explored patients was 12% (95% CI: 8-17) ( P =0.01). Heterogeneity was found to be high in the present meta-analysis ( I2 =72%; P < 0.01). For the secondary endpoint analysis, the pooled prevalence of complete remission at 1-year follow-up was 71% (0.52; 0.85), and mortality from the ACLF-AIH patient population was 32% (95% CI: 18-50). Sensitivity analysis showed no influence on the overall estimations of the pooled prevalence of ACLF by omitting studies one by one. One in 10 AIH patients likely present with ACLF. The response to treatment is seen in two-thirds of patients, and mortality is high.

Am J Med Sci 2024:S0002-9629(24)01278-3. [PMID: 38876435 DOI: 10.1016/j.amjms.2024.06.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2023] [Revised: 12/19/2023] [Accepted: 06/10/2024] [Indexed: 06/16/2024]
Abstract
INTRODUCTION AND OBJECTIVES Despite tacrolimus (TAC) or mycophenolate mofetil (MMF) for alternate approaches, a proportion of patients still required further exploration of other therapeutic options due to uncontrolled autoimmune hepatitis(AIH). The role of cyclophosphamide (CYC) for AIH has been explored in isolated case reports and small series. We present a review of CYC therapy in AIH patients. MATERIALS AND METHODS A search for studies with keywords 'autoimmune hepatitis' and 'cyclophosphamide' was performed. Data recorded included gender, age, laboratory parameters and histological findings at the time of AIH diagnosis and before initiation of CYC therapy. RESULTS We identified 13 patients across 7 studies who met criteria for study inclusion, of whom around 69.2% (9/13) were primary refractory; 30.8% (4/13) patients used CYC as rescue therapy due to their coexisting autoimmune complications. The main findings of the study were that CYC appears to have an acceptable safety profile in difficult-to-treat AIH patients, with an overall remission rate of 88.9% (8/9). The other four patients with AIH accompanied by extrahepatic autoimmune disorders also achieved remission of transaminase levels and stability of liver function after the addition of CYC. A positive response to CYC treatment was seen in 12(92.3%) patients and none of them relapsed during the follow-up. CONCLUSIONS We cautiously recommend that CYC could be a conditioning alternative to starting second-line therapy after unsuccessful intensification of first-line treatment. Pharmacogenetic methods may play a role in guiding cyclophosphamide therapy. Given our small sample size, results should be considered preliminary.

Abstract
BACKGROUND AND AIMS Non-A-E hepatitis (NAEH) not leading to acute liver failure (ALF) is poorly documented. The objective was to compare clinical and laboratory features of uncomplicated acute NAEH with acute viral (AVH) and autoimmune hepatitis (AIH) and histopathology in NAEH and AIH. METHODS Cases of hepatocellular jaundice were included. These were grouped into AVH, AIH and NAEH based on clinical, laboratory and, when indicated, liver biopsy findings. NAEH and AIH were followed up at three months. RESULTS Of 336 patients with hepatocellular jaundice, 15 (5%) were NAEH, 25 (7%) acute AIH and 45 (14%) AVH. Among NAEH patients, seven (46.7%) were males with a mean age of presentation 39 years. Jaundice (100%) was the most common presentation of NAEH. Peak bilirubin was 10.7 mg/dL. Peak aspartate and alanine aminotransferase (AST, ALT) were 512 and 670 U/L. Five (33.3%) patients had positive anti-nuclear antibody and one had anti-smooth muscle antibody. Mean immunoglobulin G (IgG) levels were 1829. On liver biopsy, all had ballooning degeneration, four (26.7%) had mild and three (20%) moderate interface hepatitis, four (26.7%) mild lymphoplasmacytic infiltrate, one (6.7%) rosette formation, bridging necrosis in none and stage 1 fibrosis in one. Comparing NAEH with AIH, AIH showed significantly older age at presentation, female predisposition, past history of jaundice, lower ALT, more autoantibodies, higher IgG, higher grade interface hepatitis, lymphoplasmacytic infiltrate, rosette formation and higher bilirubin, AST at three months. NAEH and viral hepatitis had similar features. CONCLUSION Etiology of NAEH is unlikely to be autoimmune and is probably viral, unidentified as yet. Uncomplicated NAEH likely has self-limiting course even without specific treatment.

Abstract
Autoimmune hepatitis (AIH) is a serious chronic liver disease that may last for decades and eventually develop into cirrhosis and liver failure. In recent years, people have paid more attention to the microbiome-gut-liver axis, which provides guidance for all to explore the role of microbiome in the occurrence and development of liver diseases. In this review, the possible mechanism of intestinal microbes promoting the occurrence of AIH, mainly expounding the key ways such as bacterial ecological imbalance, intestinal leakage, and molecular simulation between microbes and autoantigens is summarized. In addition, this paper also discusses that intestinal microbiome has great potential as a biomarker for early diagnosis of AIH, and intestinal microbiome is also a candidate target for prevention and treatment of AIH. Finally, the study summarizes and prospects the targeted therapy of intestinal microorganisms to prevent the occurrence and development of AIH.

Abstract
Autoimmune hepatitis is an inflammatory disease of the liver of unknown cause that may progress to liver cirrhosis and end stage liver failure if diagnosis is overlooked and treatment delayed. The clinical presentation is often that of acute hepatitis, sometimes very severe; less frequently, it can be insidious or completely asymptomatic. The disease can affect people of any age and is more common in women; its incidence and prevalence seem to be on the rise worldwide. An abnormal immune response targeting liver autoantigens and inducing persistent and self-perpetuating liver inflammation is the pathogenic mechanism of the disease. A specific set of autoantibodies, increased IgG concentrations, and histological demonstration of interface hepatitis and periportal necrosis are the diagnostic hallmarks of autoimmune hepatitis. Prompt response to treatment with corticosteroids and other immunomodulatory drugs is almost universal and supports the diagnosis. The aims of treatment are to induce and maintain long term remission of liver inflammation. Treatment can often even reverse liver fibrosis, thus preventing progression to advanced cirrhosis and its complications. Most patients need lifelong maintenance therapy, and repeated follow-up in experienced hands improves the quality of care and quality of life for affected patients.

Abstract
INTRODUCTION Autoimmune hepatitis (AIH) is a chronic liver disease with a relevant inflammatory component and an unknown etiology. Evidence for clinical characteristics and risk factors in large cohorts of patients with acute AIH (AAIH) is lacking. We clinically characterized patients with AAIH, the prevalence of a combined adverse outcome (death or liver transplantation (LT)), and its risk factors. METHODS A retrospective study of adult patients diagnosed with AAIH at three centers (Santiago, Chile; 2000-2018) was conducted. Clinical and laboratory characteristics were obtained. A liver biopsy was performed for all patients. Descriptive statistics and logistic regression models were used. RESULTS A total of 126 patients were admitted; 77% were female, 33 (26.2%) had a severe presentation, and 14 (11.1%) had a fulminant presentation. Overall, 24 patients (19.0%) lacked typical autoantibodies, and 26.2% had immunoglobulin G levels in the normal range. The most frequent histological findings were plasma cells (86.5%), interface hepatitis (81.7%), and chronic hepatitis (81.0%). Rosettes were uncommon (35.6%). Advanced fibrosis was present in 27% of patients. Combined adverse outcomes occurred in 7.9% of cases, all fulminant with histological cholestasis. Alkaline phosphatase, bilirubin, and prothrombin less than 50% were independent risk factors for in-hospital death or LT (p value <0.05). Although corticosteroid treatment was associated with better outcomes (OR 0.095, p value = 0.013), more severe patients were less likely to receive this therapy. Discussion. In this large cohort of patients with AAIH, clinical characteristics differ from those reported in patients with chronic AIH. Fulminant hepatitis, histological cholestasis, alkaline phosphatase, bilirubin, and prothrombin were associated with death/LT.

Abstract
The global burden of deaths caused by liver failure is substantial. The Asia-Pacific region is home to more than half of the global population and accounted for 62.6% of global deaths because of liver diseases in 2015. The aetiology of liver failure varies in different countries at different times. Viruses (Hepatitis A, B and E), drugs (herbs and anti-tuberculous drugs), toxins (alcohol use) and autoimmune flares are mainly responsible of majority of liver failure in individuals with normal liver (acute liver failure; ALF); else these may precipitate liver failure in those with chronic liver disease (acute-on-chronic liver failure; ACLF). Concomitant increases in alcohol misuse and metabolic syndrome in recent years are concerning. Ongoing efforts to address liver failure-related morbidity and mortality require accurate contemporary estimates of epidemiology and outcomes. In light of the ever-changing nature of liver disease epidemiology, accurate estimates for the burden of liver failure across the countries are vital for setting clinical, research and policy priorities. In this review, we aimed to describe the current as well as changing epidemiological trends of common liver failure syndromes, ALF and ACLF in the Asia-Pacific region.

Abstract
BACKGROUND AND AIMS To assess whether corticosteroids improve prognosis in patients with AS-AIH, and to identify factors at therapy initiation and during therapy predictive of the response to corticosteroids. METHODS This was a retrospective cohort study including all patients with AS-AIH admitted to 13 tertiary centres from January 2002 to January 2019. The composite primary outcome was death or liver transplantation within 90 days of admission. Kaplan-Meier and Cox regression methods were used for data analysis. RESULTS Of 242 consecutive patients enrolled (mean age [SD] 49.7 [16.8] years), 203 received corticosteroids. Overall 90-day transplant-free survival was 61.6% (95% confidence interval [CI] 55.4-67.7). Corticosteroids reduced the risk of a poor outcome (adjusted hazard ratio [HR] 0.25; 95% CI 0.2-0.4), but this treatment failed in 30.5%. An internally validated nomogram composed of older age, MELD, encephalopathy and ascites at the initiation of corticosteroids accurately predicted the response (C-index 0.82; [95% CI 0.8-0.9]). In responders, MELD significantly improved from days 3 to 14 but remained unchanged in non-responders. MELD on day 7 with a cut-off of 25 (sensitivity 62.5%[95% CI: 47.0-75.8]; specificity 95.2% [95% CI: 89.9-97.8]) was the best univariate predictor of the response. Prolonging corticosteroids did not increase the overall infection risk (adjusted HR 0.75; 95% CI 0.3-2.1). CONCLUSION Older patients with high MELD, encephalopathy or ascites at steroid therapy initiation and during treatment are unlikely to show a favourable response and so prolonged therapy in these patients, especially if they are transplantation candidates, should be avoided.

B cells in autoimmune hepatitis: bystanders or central players? Semin Immunopathol 2022; 44:411-427. [PMID: 35488094 PMCID: PMC9256567 DOI: 10.1007/s00281-022-00937-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Accepted: 04/07/2022] [Indexed: 02/07/2023]
Abstract
B cells are central for the adaptive immune system to mount successful immune responses not only as antibody producers but also as regulators of cellular immunity. These multifaceted features are also reflected in autoimmunity where autoreactive B cells can fuel disease by production of cytotoxic autoantibodies, presentation of autoantigens to autoreactive T cells, and secretion of cytokines and chemokines that either promote detrimental immune activation or impair regulatory T and B cells. The role of B cells and autoantibodies in autoimmune hepatitis (AIH) have been controversially discussed, with typical autoantibodies and hypergammaglobulinemia indicating a key role, while strong HLA class II association suggests T cells as key players. In this review, we summarize current knowledge on B cells in AIH and how different B cell subpopulations may drive AIH progression beyond autoantibodies. We also discuss recent findings of B cell-directed therapies in AIH.

Abstract
Hepatic dysfunction represents a wide spectrum of pathological changes, which can be frequently found in hepatitis, cholestasis, metabolic diseases, and focal liver lesions. As hepatic dysfunction is often clinically silent until advanced stages, there remains an unmet need to identify affected patients at early stages to enable individualized intervention which can improve prognosis. Passive liver function tests include biochemical parameters and clinical grading systems (e.g., the Child-Pugh score and Model for End-Stage Liver Disease score). Despite widely used and readily available, these approaches provide indirect and limited information regarding hepatic function. Dynamic quantitative tests of liver function are based on clearance capacity tests such as the indocyanine green (ICG) clearance test. However, controversial results have been reported for the ICG clearance test in relation with clinical outcome and the accuracy is easily affected by various factors. Imaging techniques, including ultrasound, computed tomography, and magnetic resonance imaging, allow morphological and functional assessment of the entire hepatobiliary system, hence demonstrating great potential in evaluating hepatic dysfunction noninvasively. In this article, we provide a state-of-the-art summary of noninvasive imaging modalities for hepatic dysfunction assessment along the pathophysiological track, with special emphasis on the imaging modality comparison and selection for each clinical scenario.

Abstract
Autoimmune hepatitis (AIH) is an immune-mediated type of chronic liver inflammation accompanied by intestinal flora imbalance. Probiotics have been reported to ameliorate imbalances in the intestinal flora. This study aimed to investigate the effects of compound probiotic in the AIH mouse model. AIH mice were gavaged with compound probiotic and injected intraperitoneally with dexamethasone (dex) for 42 days. The results showed that these treatments suppressed hepatic inflammatory cell infiltration, serum transaminase, and Th1 and Th17 cells. However, Treg cells were increased only in the probiotics group, which indicates an immunomodulatory role of the compound probiotic. The compound probiotic maintained intestinal barrier integrity, blocked lipopolysaccharide (LPS) translocation, and inhibited the activation of the TLR4/NF-κB pathway and the production of inflammatory factors in the liver and ileum. Moreover, the compound probiotic treatment increased the abundance of beneficial bacteria and reduced the abundance of potentially harmful bacteria in gut. Compound probiotic may improve ileal barrier function while increasing the diversity of the intestinal flora, blocking the translocation of gut-derived LPS to the liver and therefore preventing activation of the TLR4/NF-κB pathway. The resulting inhibition of pro-inflammatory factor production facilitates AIH remission.

Determinants of Outcomes in Autoimmune Hepatitis Presenting as Acute on Chronic Liver Failure Without Extrahepatic Organ Dysfunction upon Treatment With Steroids. J Clin Exp Hepatol 2021; 11:171-180. [PMID: 33746441 PMCID: PMC7953011 DOI: 10.1016/j.jceh.2020.08.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Accepted: 08/13/2020] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND AND AIMS Autoimmune hepatitis presenting as acute on chronic liver failure (AIH-ACLF) is a novel entity with limited data on clinical course and management. We assessed outcomes in patients of AIH-ACLF with no extrahepatic organ dysfunction/failure when administered steroids. METHODS In this retrospective analysis, clinical data, laboratory parameters, liver biopsy indices and prognostic scores such as model for end-stage liver disease (MELD) and Child-Turcotte-Pugh (CTP) scores at baseline were computed for patients with AIH-ACLF and compared across strata of incident infections and transplant-free survival. The primary outcome was 90-day transplant-free survival. Biochemical remission was assessed, and predictors of end points were identified. RESULTS Twenty-nine patients of AIH-ACLF were included with a median follow-up of 4 months. The 90- and 180-day transplant-free survival rates of 55.2 [95% confidence interval (CI): 39.7-76.6]% and 30.2(95% CI: 16.7-54.6)%, respectively, were attained on steroids. Three patients (10.3%) underwent liver transplant while 16 (55.2%) deaths occurred. Infections developed in 12 patients (41.3%), leading to worsening prognostic scores, new onset organ dysfunction/failure and 11 deaths. Seven of ten patients (70%) in the transplant-free survivor group attained biochemical remission on follow-up. The MELD score<24 (sensitivity: 68.4%; specificity: 80%) and CTP<11 (sensitivity: 78.9%; specificity: 90%) had best predictive value for survival, in addition to decrease in the MELD score at 2 weeks (sensitivity: 78.9%; specificity: 70%). CONCLUSION Patients with AIH-ACLF have a morbid disease course despite treatment with steroids. Patients with no extrahepatic organ failure with good baseline prognostic scores may be administered steroids with close monitoring for change in MELD over 2 weeks.

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 is associated with varied clinical presentations and natural history, as well as somewhat unpredictable treatment responses. Understanding how to stratify patients who require further escalation of therapy will help clinicians manage these patients. The presentation of acute severe autoimmune hepatitis (AS-AIH) is relatively uncommon, although its prevalence is potentially greater than currently perceived. Previous studies consist of small retrospective single-centre series and are not directly comparable due to the diversity of presentations, disease definitions and non-standardised treatment regimens. We define AS-AIH as those who present acutely with AIH and are icteric with an international normalised ratio ≥1.5 and no evidence of hepatic encephalopathy. Those with hepatic encephalopathy should be defined as having AS-AIH with acute liver failure. In this review, we provide a structured practical approach for diagnosing and managing this unique group of patients.

Abstract
Acute liver failure (ALF) is a severe condition secondary to a myriad of causes associated with poor outcomes. The prompt diagnosis and identification of the aetiology allow the administration of specific treatments plus supportive strategies and to define the overall prognosis, the probability of developing complications and the need for liver transplantation. Pivotal issues are adequate monitoring and the institution of prophylactic strategies to reduce the risk of complications, such as progressive liver failure, cerebral oedema, renal failure, coagulopathies or infections. In this article, we review the main aspects of ALF, including the definition, diagnosis and complications. Also, we describe the standard-of-care strategies and recent advances in the treatment of ALF. Finally, we include our experience of care patients with ALF.

Abstract
Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease, characterized by the elevation of aminotransferases, presence of anti-nuclear antibody or anti-smooth muscle antibody, elevated immunoglobulin G (IgG), and interface hepatitis/plasma-lymphocytic inflammation based on histology. Recent epidemiological studies have indicated an increasing trend in the prevalence of AIH worldwide, especially in male patients; this trend may suggest the alteration of environmental triggers of disease onset over time. As no disease-specific biomarker or histological finding is currently available, AIH requires a clinical diagnosis, and a validated diagnostic scoring system with acceptable specificity and sensitivity has been proposed. Regarding treatment, corticosteroids and azathioprine are recommended, and in those who exhibit an incomplete response or those who are intolerant to these drugs, second-line therapy, such as mycophenolate mofetil, is considered. Overall, the long-term outcome is excellent in patients with complete biochemical responses, while life-long maintenance treatment may be required since the cessation of immunosuppressive agents frequently leads to the relapse of the disease. Acute-onset AIH does occur, and the diagnosis is very challenging due to the lack of serum autoantibodies or elevated IgG. The unmet needs include earlier diagnosis, intervention with disseminated clinical practice guidelines, and recognition and improvement of patients’ health-related quality of life with the development of novel corticosteroid-free treatment regimens.

Abstract
Acute liver failure (ALF) is an infrequent, unpredictable, potentially fatal complication of acute liver injury (ALI) consequent to varied etiologies. Etiologies of ALF as reported in the literature have regional differences, which affects the clinical presentation and natural course. In this part of the consensus article designed to reflect the clinical practices in India, disease burden, epidemiology, clinical presentation, monitoring, and prognostication have been discussed. In India, viral hepatitis is the most frequent cause of ALF, with drug-induced hepatitis due to antituberculosis drugs being the second most frequent cause. The clinical presentation of ALF is characterized by jaundice, coagulopathy, and encephalopathy. It is important to differentiate ALF from other causes of liver failure, including acute on chronic liver failure, subacute liver failure, as well as certain tropical infections which can mimic this presentation. The disease often has a fulminant clinical course with high short-term mortality. Death is usually attributable to cerebral complications, infections, and resultant multiorgan failure. Timely liver transplantation (LT) can change the outcome, and hence, it is vital to provide intensive care to patients until LT can be arranged. It is equally important to assess prognosis to select patients who are suitable for LT. Several prognostic scores have been proposed, and their comparisons show that indigenously developed dynamic scores have an edge over scores described from the Western world. Management of ALF will be described in part 2 of this document.

Abstract
Aim of the study Autoimmune hepatitis (AIH), despite being uncommon, is on the rise in the elderly population. However, no study from India has described the natural history and treatment outcome of AIH in the elderly. The aim was to study the characteristics of AIH in the elderly population and compare them with the younger population. Material and methods Patients with a diagnosis of AIH based on the revised International Autoimmune Hepatitis Group (IAIHG) criteria were recruited from January 2011 to June 2018. Patients were defined as elderly when ≥ 60 years and young when < 60 years of age. Clinical, serological, histological characteristics and treatment outcome with follow-up until 12 months were analyzed and compared between the two groups. Results Out of 155 patients, 33 (21.29%) were elderly. Acute-on-chronic liver failure (ACLF) as the presentation was more common in elderly as compared to young AIH patients (39.4% vs. 13.9%, p = 0.0024). Serum alanine aminotransferases and serum creatinine levels were significantly higher in elderly patients as compared to the younger group (p < 0.05). On histology cirrhosis was significantly more common in the elderly group (75.7% vs. 56.6%, p = 0.045). Response to treatment at the end of 12 months was similar in both groups. Due to co-morbidities immunosuppressant could not be started in 18.2% of elderly and 6.5% of younger patients (p = 0.065). Conclusions AIH is an important differential diagnosis among the elderly population presenting with ACLF and cirrhosis. When given appropriate immunosuppressants they have a similar outcome as compared to the youngest population.

Abstract
BACKGROUND Autoimmune hepatitis (AIH) is a rare progressive liver disease, which manifests as acute hepatitis in 40%-50% of pediatric cases. This refers predominantly to spontaneous exacerbations of previously unrecognized subclinical AIH with laboratory and histological signs of chronic hepatitis, or to acute exacerbations of known chronic disease. Only a few of these patients fulfill criteria for acute liver failure (ALF). METHODS Forty children diagnosed with AIH in our center between 2000 and 2018 were included in this study. All of them fulfilled revised diagnostic criteria of the International Autoimmune Hepatitis Group (IAIHG) for probable or confirmed AIH, and other etiologies of liver diseases were excluded. Patients were divided into two groups: acute AIH (A-AIH) or chronic AIH (C-AIH). RESULTS Acute onset of AIH occurred in 19/40 children (48%). Six of them fulfilled the criteria of ALF with coagulopathy and encephalopathy. Five of 6 children with ALF suffered from exacerbation of previously undiagnosed chronic AIH, among which 4 children were histologically confirmed as micronodular cirrhosis. The remaining one patient had fulminant AIH with centrilobular necrosis, but no histological signs of previous chronic liver damage. We observed significantly lower levels of albumin, higher levels of aminotransferases, bilirubin, INR, IgG, higher IAIHG score and more severe histological findings in A-AIH than in C-AIH. No differences in patient age and presence of autoantibodies were observed between A-AIH and C-AIH. All children, including those with ALF and cirrhosis, were treated with corticosteroids, and are alive and achieved AIH remission. Liver transplant was not indicated in any patient. CONCLUSION Rapid and accurate diagnosis of A-AIH may be difficult. However, timely start of immunosuppressive therapy improves prognosis and decreases number of indicated liver transplantations in children with AIH.

Abstract
Autoimmune hepatitis (AIH) is considered less common in the Asia Pacific region. Due to this, AIH flare as a cause of acute on chronic liver failure (ACLF) is often overlooked and treatment delayed. We aimed at the defining clinical and histopathological spectrum and role of steroid therapy in AIH-ACLF. Patients with AIH-ACLF, prospectively recruited and followed between 2012 and 2017, were analyzed from the Asian Pacific Association for the Study of the Liver ACLF Research Consortium (AARC) data base. Diagnosis of AIH was confirmed using International Autoimmune Hepatitis Group score or simplified AIH score with histopathological evidence. Of 2,825 ACLF patients, 82 (2.9%) fulfilled criteria of AIH (age 42.1 ± 18.1 years, 70% female). At baseline, mean bilirubin was 18.6 ± 8.2 mg/dL, Child-Turcotte-Pugh score was 11.7 ± 1.4, and Model for End-Stage Liver Disease (MELD) score was 27.6 ± 6.5. Mean immunoglobulin G was 21.61 ± 7.32 g/dL, and this was elevated ≥1.1 times in 97% of cases; 49% were seronegative. Liver histology was available in 90%, with median histological activity index of 10 (interquartile range, 7-12); 90% with moderate to severe interface activity; 56% showing significant parenchymal necrosis (bridging and confluent necrosis); and cirrhosis in 42%. Twenty-eight (34%) patients received steroid therapy and showed shorter intensive care unit (ICU) stay (median 1.5 versus 4 days, P < 0.001) and improved 90-day survival (75% versus 48.1%, P = 0.02) with comparable incidence of sepsis (P = 0.32) compared to those who did not. Patients of advanced age, more severe liver disease (MELD >27; 83.3% sensitivity, 78.9% specificity, area under the receiver operating characteristic curve 0.86), presence of hepatic encephalopathy, and fibrosis grade ≥F3 had an unfavorable response to corticosteroid therapy. Conclusion: AIH presenting as ACLF is not uncommon in Asian patients; a low threshold for liver biopsy is needed to confirm the diagnosis as nearly half the patients are seronegative; early stratification to steroid therapy or liver transplantation (MELD >27, hepatic encephalopathy in ≥F3) would reduce ICU stay and improve outcomes.

Abstract
Acute severe presentations of autoimmune hepatitis (AIH) represent a challenge for the transplant community. As a disease, it is poorly characterized, and there is a weak evidence base to guide diagnosis and treatment. Early identification of acute severe AIH is key because it determines the initiation of corticosteroids, which can be lifesaving. However, their use in this setting remains controversial. The Model for End-Stage Liver Disease score, severity of coagulopathy, and grade of encephalopathy may be predictors of outcome with corticosteroid therapy. The optimal timing of liver transplantation (LT) can be difficult to determine and, as such, the decision to proceed to transplantation should not be delayed by protracted courses of corticosteroids. The aim of this review is to better characterize this subset of patients; to differentiate them clinically, serologically, and histologically from chronic AIH and other causes of acute liver failure; and to present the role, predictors, and optimal timings of corticosteroid therapy and LT. Although this review is specific to adults, many principles hold true for the pediatric population.

Abstract
BACKGROUND Mycophenolate mofetil is a commonly used salvage therapy for patients with autoimmune hepatitis (AIH). AIM To evaluate the predictors of response to mycophenolate rescue therapy to facilitate clinical decision making. METHODS We performed a retrospective observational cohort study of AIH patients managed in 17 major Australian liver centres who received mycophenolate after an inadequate response or intolerance to corticosteroids with/without thiopurine(s). Baseline demographic, clinical and laboratory variables were compared between responders and nonresponders. A multivariable logistic regression model was developed using forward selection to identify independent predictors of treatment response. RESULTS A total of 105 patients received mycophenolate rescue therapy of whom 63 (60%) achieved biochemical remission. On univariable analysis, older age (P = 0.003), INR < 1.1 (P = 0.02), and lower immunoglobulin gamma (IgG; P < 0.002) levels were associated with treatment response, while no association was found with cirrhosis status (P = 0.07) or treatment indication (P = 0.63). On multivariable analysis, lower pre-treatment serum IgG level (P = 0.01), higher age at commencing mycophenolate (P = 0.01) and higher INR (P = 0.03) were the only significant independent predictors. An IgG level <17 g/L had a positive and negative predictive value for response of 71% and 60% respectively, while age ≥54 years when commencing mycophenolate had a positive and negative predictive value for response of 80% and 59% respectively. CONCLUSION Mycophenolate remains an excellent treatment option for patients with AIH refractory to or intolerant of standard therapy with those most likely to benefit being older and/or having lower pre-treatment IgG levels.

Abstract
Autoimmune hepatitis (AIH) is a relatively rare acute or chronic liver disease of unknown etiology characterized by large heterogeneity. Its distribution is global, covering all ages, both sexes and all ethnic groups. The aim of the present Clinical Practice Guidelines (CPG) of the Hellenic Association for the Study of the Liver was to provide updated guidance and help to gastroenterologists, hepatologists, internists and general practitioners for AIH diagnosis and management. AIH diagnosis is based on clinicopathological characteristics: namely, polyclonal hypergammaglobulinemia, particularly of immunoglobulin G (IgG), circulating autoantibodies, interface hepatitis on liver histology, absence of viral hepatitis, and a favorable response to immunosuppression. Clinical manifestations at disease onset are variable, ranging from asymptomatic to the acute/severe form. Aminotransferase and bilirubin levels vary, while the presence of hepatitis at the histological level is a prerequisite for diagnosis. Autoantibodies are the hallmark for AIH diagnosis; therefore, the CPG describe the appropriate serological algorithm for their detection. AIH therapy should aim to achieve complete biochemical (normalization of IgG and aminotransferases) and histological remission. All patients who have active disease, even those with cirrhosis, should be treated with individualized and response-guided induction therapy using prednisolone in combination with azathioprine or mycophenolate mofetil as first-line therapy. Immunosuppression should be given for at least 3 years and for at least 2 years after the achievement of complete biochemical response, while a liver biopsy should be recommended before treatment discontinuation. Current CPG are also provided for several specific conditions and difficult-to-treat patients.

Acute-on-chronic liver failure (ACLF) is a distinct syndrome of liver failure in a patient with chronic liver disease presenting with jaundice, coagulopathy and ascites and/or hepatic encephalopathy, developing following an acute hepatic insult and associated with high 28-day mortality. The definition though lacks global consensus, excludes patients with known distinct entities such as acute liver failure and those with end-stage liver disease. The initial Systemic Inflammatory Response Syndrome (SIRS) because of cytokine storm in relation to acute insult and/or subsequent development of sepsis due to immunoparalysis leads to extrahepatic organ failure. These cascades of events progress through a 'Golden Window' period of about 7 days, subsequent to which majority of the patients develop complications, such as sepsis and extrahepatic organ failure. Prevention of sepsis, support of organs and management of organ failure (commonly hepatic, renal, cerebral, coagulation) and early referral for transplant is crucial. The APASL ACLF research consortium (AARC) liver failure score is a dynamic prognostic model for management decisions and is superior to existing models. Aggressive multidisciplinary approach can lead to a transplant-free survival in nearly half of the cases. The present review provides an algorithmic approach to management of organ failure, sepsis prevention, use of dynamic prognostic models for management decision and is aimed to improve the skills for managing and improving the outcomes of such critically ill patients.

Buechter M, Manka P, Heinemann FM, Lindemann M, Baba HA, Schlattjan M, Canbay A, Gerken G, Kahraman A. Potential triggering factors of acute liver failure as a first manifestation of autoimmune hepatitis-a single center experience of 52 adult patients. World J Gastroenterol 2018; 24:1410-1418. [PMID: 29632422 PMCID: PMC5889821 DOI: 10.3748/wjg.v24.i13.1410] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2017] [Revised: 02/21/2018] [Accepted: 03/03/2018] [Indexed: 02/06/2023] Open
Abstract
AIM To investigate potential triggering factors leading to acute liver failure (ALF) as the initial presentation of autoimmune hepatitis (AIH). METHODS A total of 565 patients treated at our Department between 2005 and 2017 for histologically-proven AIH were retrospectively analyzed. However, 52 patients (9.2%) fulfilled the criteria for ALF defined by the "American Association for the Study of the Liver (AASLD)". According to this definition, patients with "acute-on-chronic" or "acute-on-cirrhosis" liver failure were excluded. Following parameters with focus on potential triggering factors were evaluated: Patients' demographics, causation of liver failure, laboratory data (liver enzymes, MELD-score, autoimmune markers, virus serology), liver histology, immunosuppressive regime, and finally, outcome of our patients. RESULTS The majority of patients with ALF were female (84.6%) and mean age was 43.6 ± 14.9 years. Interestingly, none of the patients with ALF was positive for anti-liver kidney microsomal antibody (LKM). We could identify potential triggering factors in 26/52 (50.0%) of previously healthy patients presenting ALF as their first manifestation of AIH. These were drug-induced ALF (57.7%), virus-induced ALF (30.8%), and preceding surgery in general anesthesia (11.5%), respectively. Unfortunately, 6 out of 52 patients (11.5%) did not survive ALF and 3 patients (5.7%) underwent liver transplantation (LT). Comparing data of survivors and patients with non-recovery following treatment, MELD-score (P < 0.001), age (P < 0.05), creatinine (P < 0.01), and finally, ALT-values (P < 0.05) reached statistical significance. CONCLUSION Drugs, viral infections, and previous surgery may trigger ALF as the initial presentation of AIH. Advanced age and high MELD-score were associated with lethal outcome.

Abstract
Autoimmune hepatitis (AIH) is a progressive immune mediated liver disease of unknown origin. Key diagnostic features include hypergammaglobulinemia/elevated serum-IgG, characteristic circulating autoantibodies, periportal hepatitis with interface activity on liver biopsy and the exclusion of hepatotropic viruses. However, the diagnosis is challenging in cholestatic and severe presentations. It can be difficult to differentiate AIH from drug-induced liver injury. Although many patients initially respond to standard immunosuppressive therapy, a significant proportion experiences intolerable side effects or insufficient treatment response. This underlines the need for effective alternative treatment options, which are still very limited and based on rather poor evidence. This review summarises core aspects of the clinical management of AIH with focus on recent achievements and unmet needs.
