Abstract
BACKGROUND AND AIMS The International AIH Pathology Group (IAIH-PG) put forward the new histological criteria of autoimmune hepatitis (AIH) in 2022, which have not undergone adequate verification. In this study, we verified the applicability of the new histological criteria in the population of Chinese patients with chronic liver disease, comparing it with the simplified criteria. METHODS The gold standard for diagnosis in all patients was based on histological findings, combined with clinical manifestations and laboratory tests and determined after a follow-up period of at least 3 years. A total of 640 patients with various chronic liver diseases from multiple centres underwent scoring using the new histological criteria and the simplified criteria, comparing their diagnostic performance. RESULTS In this study, the new histological criteria showed a sensitivity of 73.6% and 100% for likely and possible AIH, with specificities of 100% and 69.0% respectively. The coincidence rates of possible AIH for the new histological criteria, simplified histological criteria and simplified score were 81.7%, 72.8% and 69.7% respectively. For likely AIH, the rates were 89.2%, 75.9% and 65.6% respectively. Based on the new histological criteria, all patients with AIH were correctly diagnosed. Specifically, 73.6% were diagnosed with likely AIH and 26.4% were possible AIH. Additionally, the simplified histological criteria achieved a diagnosis rate of 98.6% for AIH, while the simplified score could only diagnose 53.8% of AIH. CONCLUSIONS Compared with the simplified score and simplified histological criteria, the sensitivity and specificity of the new histological criteria for AIH were significantly improved. The results indicate that the new histological criteria exhibit high sensitivity and specificity for diagnosing AIH in China.

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

Abstract
Autoimmune hepatitis (AIH) presents a diagnostic challenge because it is relatively rare and heterogenous in presentation. This article presents the currently adopted approach to AIH diagnosis and explores the challenges with accurately identifying this disease entity. AIH offers no pathognomonic findings, instead relies on clinical presentation, serology, and histology to make the diagnosis. Diagnostic scoring systems support clinical judgment and serve as valuable tools in diagnosis and research. Histological analysis remains the cornerstone of diagnosis and to this day biopsy is essential to make the diagnosis.

Abstract
BACKGROUND AND AIMS There is no golden standard for the diagnosis of autoimmune hepatitis which still dependent on liver biopsy currently. So, we developed a noninvasive prediction model to help optimize the diagnosis of autoimmune hepatitis. METHODS From January 2017 to December 2019, 1739 patients who had undergone liver biopsy were seen in the second hospital of Nanjing, of which 128 were here for consultation. Clinical, laboratory, and histologic data were obtained retrospectively. Multivariable logistic regression analysis was employed to create a nomogram model that predicting the risk of autoimmune hepatitis. Internal and external validation was both performed to evaluate the model. RESULTS A total of 1288 patients with liver biopsy were enrolled (1184 from the second hospital of Nanjing, the remaining 104 from other centers). After the univariate and multivariate logistic regression analysis, nine variables including ALT, IgG, ALP/AST, ALB, ANA, AMA, HBsAg, age, and gender were selected to establish the noninvasive prediction model. The nomogram model exhibits good prediction in diagnosing autoimmune hepatitis with AUROC of 0.967 (95% CI: 0.776-0.891) in internal validation and 0.835 (95% CI: 0.752-0.919) in external validation. CONCLUSIONS ALT, IgG, ALP/AST, ALB, ANA, AMA, HBsAg, age, and gender are predictive factors for the diagnosis of autoimmune hepatitis in patients with unexplained liver diseases. The predictive nomogram model built by the nine predictors achieved good prediction for diagnosing autoimmune hepatitis.

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.

Prevalence and Significance of Antinuclear Antibodies in Biopsy-Proven Nonalcoholic Fatty Liver Disease: A Systematic Review and Meta-Analysis. DISEASE MARKERS 2022; 2022:8446170. [PMID: 35990246 PMCID: PMC9391168 DOI: 10.1155/2022/8446170] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 06/06/2022] [Accepted: 06/30/2022] [Indexed: 12/27/2022]
Abstract
Aim Associations between antinuclear antibodies (ANAs) and disease severity in nonalcoholic fatty liver disease (NAFLD) remain unclear. This study aimed to provide reliable estimates of ANA prevalence in subjects with biopsy-proven NAFLD and to investigate whether its associations with liver disease severity were established. Methods Observational studies measuring ANA in NAFLD patients were derived from the PubMed, Embase, and Web of Science databases from inception to March 30, 2022. The effect size was presented as the pooled risk difference, unstandardized mean differences (MDs), and odds ratio (OR) with a 95% confidence interval (CI). Results Thirteen articles involving 2331 patients were finally included. Among the subjects with biopsy-proven NAFLD, the overall prevalence of ANA positivity was high as 23% (95% CI: 19%-28%), but there were no statistically significant differences between ANA-positive and ANA-negative NAFLD patients in the levels of liver enzymes and blood lipids, grades of hepatocellular ballooning, lobular and portal inflammation, or risks of moderate-severe steatosis and significant fibrosis. However, the subgroup analysis showed that different geographic regions led to diverse results. ANA positivity was associated with a significantly elevated risk of significant fibrosis in the Eastern population (OR = 2.30, 95% CI: 1.30-4.06) but not in the Western population (OR = 1.00, 95% CI: 0.54-1.83). Conclusions Serum ANA was present in approximately one-quarter of subjects with biopsy-proven NAFLD, but it conferred a greater risk of significant fibrosis only in Eastern but not Western populations.

Abstract
INTRODUCTION Auto-immune hepatitis (AIH) is a rare condition which primarily affects young women. Several diagnostic scoring systems exist based on clinical, biochemical, immunologic and histologic characteristics of AIH. Additionally, prognostic parameters can be identified. The purpose of this literature review is to compare the clinical value, strengths and limitations of these diagnostic and prognostic scoring systems. METHODS A literature search was performed in two databases and selected based on diagnostic and prognostic criteria. Only studies concerning AIH in adults were included. RESULTS The backbone of scoring systems remains the revised AIH criteria published in 1999 and the simplified from 2008. The revised system shows a higher sensitivity, lower specificity and lower diagnostic accuracy compared to the simplified. Limitations to these scoring systems include limited diagnostic accuracy in acute or fulminant liver failure, insufficient inclusion of atypical auto-antibodies and lacking diagnostic power in presence of overlap syndromes. Concerning these overlap syndromes, the Paris criteria show a higher diagnostic accuracy compared to the scoring systems for AIH. Presently, no clinical prognostic scoring systems are available. However, a first system based on response to treatment accurately predicts long-term survival in AIH. CONCLUSION Diagnostic scoring systems are useful in diagnosing AIH and have complementary value. However, they are no substitute for the gold standard of appropriate clinical assessment and are mostly useful in defining cohorts for research purposes. An evolution towards a more dynamic scoring system, using prognostic parameters and the progression of typical features, seems more valuable than the current diagnostic systems.

Abstract
BACKGROUND AND AIMS Some previous studies reported serum autoantibody positivity in patients with nonalcoholic fatty liver disease (NAFLD). The clinical significance of these findings remains uncertain. We aimed to investigate the association between the presence of serum autoantibodies and liver disease severity in NAFLD. METHODS AND RESULTS A total of 388 consecutive patients with biopsy-proven NAFLD were included in the study. Various serum autoantibodies (including also anti-nuclear antibodies [ANA]) were detected by indirect immunofluorescent or immunoblotting assays. Overall, 84 (21.6%) patients with biopsy-confirmed NAFLD had positivity for at least one of the measured serum autoantibodies. ANA positivity was present in 50 (12.9%) patients, whereas anti-U1RNP or pANCA antibodies were detectable in 9 (2.3%) and 6 (1.5%) patients, respectively. Multivariate logistic regression analysis showed that ANA positivity (adjusted-odds ratio: 4.51, 95%CI: 1.77-11.5; P = 0.002) or positivity of any serum autoantibodies (adjusted-odds ratio: 3.14, 95%CI: 1.30-7.62; P = 0.01) were independently associated with advanced liver fibrosis (stages F3-F4). In serum autoantibody/ANA-positive patients, the proportion of those with advanced fibrosis was also greater among carriers of PNPLA3 rs738409 GG or CG than among those carrying PNPLA3 rs738409 CC genotype. CONCLUSIONS Serum autoantibody positivity was independently associated with advanced liver fibrosis in patients with biopsy-proven NAFLD. The presence of serum autoantibodies in patients with advanced fibrosis occurred more frequently amongst those carrying PNPLA3 rs738409 GG or CG genotypes.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is nowadays the most common liver disease worldwide. Autoimmune hepatitis (AIH) is a relatively rare disease of the liver characterised by female predominance, circulating autoantibodies, polyclonal hypergammaglobulinaemia, interface hepatitis on histology and favourable response to immunosuppression. The possibility of an additional AIH diagnosis in patients with NAFLD (NAFLD/AIH concurrence) or the presence of AIH alone instead of a supposed NAFLD diagnosis represents a challenge for clinicians. We report herein two adult patients (a 33-year-old woman and a 59-year-old man) with a previous NAFLD diagnosis who proved finally to suffer from AIH alone. These two representative cases indicate how difficult and complicated could be sometimes the diagnosis of patients with AIH highlighting the range of disease manifestations and severity while they also underline that although NAFLD is by far the most frequent chronic liver disease this could not be always the case.

Abstract
BACKGROUND Two-dimensional shear-wave elastography (2D-SWE) is an ultrasound-based real-time 2D-SWE imaging technique for noninvasive assessment of liver fibrosis. The diagnostic performance of 2D-SWE for assessing liver fibrosis in patients with autoimmune hepatitis (AIH) has not been reported. AIMS To evaluate the diagnostic performance of 2D-SWE and serologic tests including the aspartate amino transferase-to-platelet ratio index (APRI) and fibrosis-4 index (FIB-4) for liver fibrosis staging in patients with AIH. METHODS 103 patients were retrospectively collected. Liver fibrosis was staged according to the Scheuer scoring system. The areas under the receiver operating characteristic curves (AUROCs) were used to assess the accuracy of 2D-SWE and serum fibrosis models for staging liver fibrosis. RESULTS Liver stiffness measured by 2D-SWE had a strong correlation with histological fibrosis stage (r = 0.71, P < 0.0001). The AUROCs of liver stiffness in detecting significant fibrosis, severe fibrosis, and cirrhosis were 0.84, 0.84, and 0.94, respectively. The AUROCs of liver stiffness for detecting significant fibrosis and severe fibrosis were higher than those of APRI (0.57, 0.56) and FIB-4 (0.63, 0.66), respectively. The cut-off liver stiffness values for predicting significant fibrosis, severe fibrosis, and cirrhosis were 10.0, 15.8, and 19.3 kPa, respectively. CONCLUSIONS 2D-SWE shows promising diagnostic performance for staging liver fibrosis in patients with AIH.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease (almost 25% of the general population). Autoimmune hepatitis (AIH) is a relatively rare liver disease of unknown aetiology characterized by female predominance and large heterogeneity regarding epidemiology, clinical manifestations, genetics, serology and liver pathology. The potential NAFLD/AIH coincidence or an AIH diagnosis alone instead of NAFLD represent a challenge for clinicians, both in making a correct and timely diagnosis but also in the management of these diseases. The diagnosis of both diseases can be challenging as: (a) reliable laboratory tests to confidently diagnose or exclude NAFLD or AIH are missing; (b) physicians and pathologists are much more familiar with a very common disease like NAFLD so, they do not consider an alternative or additional diagnosis; (c) most NAFLD studies do not investigate the patients for all autoantibodies involved in AIH diagnosis, apply the diagnostic scoring systems for AIH or address the possibility of AIH features on liver histology and (d) the recent European and American practice guidelines for NAFLD do not mention clearly the importance of IgG determination and liver autoimmune serology according to the AIH guidelines. Patients with NAFLD/AIH coincidence have significantly more frequently hypertension, diabetes, obesity, older age, lower transaminases, bilirubin and simplified score for AIH diagnosis but no female predominance compared to AIH patients only. The true outcome of NAFLD/AIH patients is practically unknown while their management is quite problematic because official clinical practice guidelines for this condition are missing.

Niţă AF, Păcurar D. Adequacy of scoring systems in diagnosing paediatric autoimmune hepatitis: retrospective study using a control group children with Hepatitis B infection. Acta Paediatr 2019; 108:1717-1724. [PMID: 30703247 DOI: 10.1111/apa.14730] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2018] [Revised: 11/20/2018] [Accepted: 01/25/2019] [Indexed: 12/27/2022]
Abstract
AIM To evaluate how correct is made the diagnosis of autoimmune hepatitis (AIH) in children, comparing the adults scoring systems - the 1999 revised scoring system by International Autoimmune Hepatitis Group and the 2007 Simplified Scoring System. The inaccuracies in diagnosis have been analysed. METHODS The two scoring systems have been applied for 28 children with AIH pre-treatment and 28 with Hepatitis B infection - matched by sex and age, all diagnosed between 2010 and 2017 in an emergency children's hospital in Bucharest, Romania. They were retrospectively followed throughout the period assessed. RESULTS Autoimmune hepatitis was present in 85.7% cases according to the 1999 revised score, respectively, 57.0% as per the 2007 simplified score. The 2007 simplified score led to false negative results when AIH was associated with another autoimmune disease (p = 0.009). Patients who did not undergo liver biopsy were associated with a downgraded diagnosis by the 2007 simplified score (p = 0.001). CONCLUSION There is a need for a scoring system tailored to children's characteristics. Two compulsory components of the future score might be liver biopsy and associated autoimmune disorders. The existing scores could be used in children with consideration, preferably both at once and together with liver biopsy for increased accuracy.

Abstract
BACKGROUND Children with autoimmune hepatitis (AIH) often exhibit particular features. Accordingly, seven pediatric-specific criteria have been proposed. AIM To develop a prediction model based on them, transform it into a scoring system and study its accuracy. METHODS A cohort of children under study for liver disease was consecutively selected. AIH diagnosis was based on classical criteria. Already proposed pediatric criteria were recorded. The best possible regression model was selected, and the beta coefficient of each criterion was translated into a whole number (points). Total scores were obtained following the points system and the best cut-off was calculated. Subsequently, accuracy of the diagnostic score was studied in the validation set. RESULTS Among 212 included patients, 100 had AIH. The score included 5 criteria: autoantibodies (0-2 points), hypergammaglobulinemia, exclusion of viral hepatitis, exclusion of Wilson's disease (1 point each) and liver histology (3 points). In addition, a normal cholangiogram is mandatory. The validation set was formed of 70 patients (24 with AIH). In this subsample, a score of ≥6 renders a sensitivity/specificity of 95.8%/100%. The area under the receiver operating characteristic curve was 97.1%. CONCLUSION Pediatric-specific criteria for the diagnosis of AIH can be reliably used as a scoring system.

Abstract
BACKGROUND/OBJECTIVES Several studies have been conducted on the accuracy of simplified criteria for autoimmune hepatitis that were presented in 2008 as an alternative to original criteria. Our purpose is to summarize the evidence available regarding their accuracy in children and to carry out a basic clinical decision analysis based on it. METHODS Electronic and manual searches were performed with keywords related to diagnostic validity terms. Data from included studies were extracted, and summary estimates of accuracy measures were calculated. An effect model was chosen depending on heterogeneity, and the presence of publication bias was also studied. Therapeutic threshold was calculated based on the already published data. Through a Bayesian approach, simplified criteria's clinical utility was simulated, taking into account the meta-analyzed indicators and several assumptions on the prevalence of autoimmune hepatitis. RESULTS The search yielded 166 studies, four of which were finally included, providing a total population of 437 patients. Pooled sensitivity and specificity of the simplified criteria for the diagnosis of autoimmune hepatitis in children was 77% and 95%, respectively, with a diagnostic odds ratio of 67. No evidence of publication bias was found. For prevalences ranging from 8.5 to 85.7, the predictive value of either a positive or a negative result moved beyond the therapeutic threshold (estimated at 56%). CONCLUSIONS The simplified criteria show high specificity and moderate sensitivity for the diagnosis of autoimmune hepatitis in children. A positive result can justify starting a therapeutic assay, but a negative result does not seem sufficient to rule out this condition.

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.

Abstract
INTRODUCTION AND AIM In 2008 the International autoimmune hepatitis (AIH) Group proposed the simplified diagnostic criteria for this disease. The original cohort study was performed in 11 international centers, but validation studies are scarce in Latin-America. The aim of this study is validate these criteria in Hispanic patients. MATERIAL AND METHODS A retrospective cohort of patients undergoing percutaneous liver biopsy and follow-up of at least 12 months was recruited from a Chilean University hospital. Patients with previous immunosuppressive therapy and liver transplant recipients were excluded. The diagnostic accuracy was analyzed using as gold standard the clinical course during long-term follow-up. Sensitivity, specificity, positive and negative predictive values (PPV and NPV) and area under the ROC curve (AUROC) were calculated. RESULTS Four hundred eighty one patients were evaluated, 294 were included. 218 (74.15%) were female, mean age 48.5 (± 12.3) years, mean follow-up 34 (± 18) months. 66 patients had AIH or overlap syndrome (22.45%), 96 (32.65%) non-alcoholic steatohepatitis, 40 (13.61%) primary biliary cholangitis, 31 (10.54%) hepatitis C, 8 (2.72%) hepatitis B, 53 (18.02%) other etiologies. The AUROC for AIH simplified criteria was 0.976. Using a cutoff ≥ 6 and ≥ 7 points, the sensitivity was 86.4% and 54.6%; specificity, 98.7% and 99.6%; PPV, 95% and 97.3%; and NPV, 96.2% and 88.6%, respectively. CONCLUSION Simplified criteria for the diagnosis of AIH have a high accuracy in our Chilean-Hispanic cohort. The female gender is strongly associated to AIH and could help in difficult cases. Further studies with a prospective design are necessary to confirm these observations.

Abstract
Autoimmune hepatitis (AIH) is a severe liver disease that affects children and adults worldwide. The diagnosis of AIH relies on increased serum transaminase and immunoglobulin G levels, presence of autoantibodies and interface hepatitis on liver histology. AIH arises in genetically predisposed individuals when a trigger, such as exposure to a virus, leads to a T cell-mediated autoimmune response directed against liver autoantigens; this immune response is permitted by inadequate regulatory immune control leading to a loss of tolerance. AIH responds favourably to immunosuppressive treatment, which should be started as soon as the diagnosis is made. Standard regimens include fairly high initial doses of corticosteroids (prednisone or prednisolone), which are tapered gradually as azathioprine is introduced. For those patients who do not respond to standard treatment, second-line drugs should be considered, including mycophenolate mofetil, calcineurin inhibitors, mechanistic target of rapamycin (mTOR) inhibitors and biologic agents, which should be administered only in specialized hepatology centres. Liver transplantation is a life-saving option for those who progress to end-stage liver disease, although AIH can recur or develop de novo after transplantation. In-depth investigation of immune pathways and analysis of changes to the intestinal microbiota should advance our knowledge of the pathogenesis of AIH and lead to novel, tailored and better tolerated therapies.

Abstract
PURPOSE Classical criteria for diagnosis of autoimmune hepatitis (AIH) are intended as research tool and are difficult to apply at patient's bedside. We aimed to study the accuracy of simplified criteria and the concordance with the expert diagnosis based on the original criteria. METHODS A cohort of children under study for liver disorder was selected through consecutive sampling to obtain the prevalence of AIH within the group of differential diagnoses. AIH was defined, based on classical criteria, through committee review of medical reports. Validity indicators of the simplified criteria were obtained in an intention to diagnose approach. Optimal cut-off and the area under the receiver operating characteristic (ROC) curve were calculated. RESULTS Out of 212 cases reviewed, 47.2% were AIH. For the optimal cut-off (6 points), the simplified criteria showed a sensitivity of 72.0% and a specificity of 96.4%, with a 94.7% positive and a 79.4% negative predictive value. The area under the ROC curve was 94.3%. There was a good agreement in the pre-treatment concordance between the classical and the simplified criteria (kappa index, 0.775). CONCLUSION Simplified criteria provide a moderate sensitivity for the diagnosis of AIH, but may help in indicating treatment in cases under suspicion with 6 or more points.

Abstract
Autoimmune hepatitis has been considered as a relatively rare immunological liver disease, especially in the Asia-Pacific area. Although the diagnosis criteria and immunosuppressive treatment regimens have been established, there are still some challenges. According to the different presentations, the personalized management of patients who suffer from this disease, including those with chronic or acute severe onset, the autoantibody-negative phenotype and cirrhosis are necessarily descriptive. Each subgroup of patients should receive an individualized therapy. Here, we review the recent studies of autoimmune hepatitis, mainly focusing on the epidemiology and genetics, personalized diagnostics, individualized treatment strategies, special subgroups and outcomes. Most of the research in the literature is based on Japanese and Chinese populations.

Abstract
Serology is key to the diagnosis of autoimmune hepatitis (AIH). Clinicians need to be aware of which tests to request, how to interpret the laboratory reports, and be familiar with the laboratory methodology. If correctly tested, >95% of AIH patients show some serological reactivity. Indirect immunofluorescence on triple rodent tissue is recommended as first screening step, since it allows the detection of all liver-relevant autoantibodies, except for anti-soluble liver antigen (SLA) antibody, which needs to be detected by molecular based assays. The threshold of immunofluorescence positivity is a titer equal or exceeding 1/40, but for patients younger than 18years even lower titers are clinically significant. Anti-nuclear antibody (ANA) and/or anti-smooth muscle (SMA) antibody characterize type 1 AIH. ANA in AIH typically shows a homogeneous staining pattern on HEp2 cells, without any specific target antigen. Anti-SMA displays different staining patterns on indirect immunofluorescence: the vascular/glomerular (VG) and the vascular/glomerular/tubular (VGT) patterns are considered specific for AIH, whilst the V pattern can be found in a variety of diseases. Type 2 AIH, which is rare and affects mostly children/adolescents, is characterized by anti-liver kidney microsomal 1 and/or anti-liver cytosol 1 antibodies. The presence of anti-neutrophil cytoplasmic antibody (ANCA), particularly atypical p-ANCA (pANNA), points to the diagnosis of AIH, especially in absence of other autoantibodies. Since it is associated with sclerosing cholangitis and inflammatory bowel disease, these conditions have to be ruled out. The only antibody specific for AIH is anti-SLA, which is associated with a more severe disease course.

Abstract
Autoimmune hepatitis is a rare chronic inflammatory liver disease, affecting all ages, characterised by elevated transaminase and immunoglobulin G levels, positive autoantibodies, interface hepatitis at liver histology and good response to immunosuppressive treatment. If untreated, it has a poor prognosis. The aim of this review is to summarize the evidence for standard treatment and to provide a systematic review on alternative treatments for adults and children. Standard treatment is based on steroids and azathioprine, and leads to disease remission in 80%-90% of patients. Alternative first line treatment has been attempted with budesonide or cyclosporine, but their superiority compared to standard treatment remains to be demonstrated. Second-line treatments are needed for patients not responding or intolerant to standard treatment. No randomized controlled trials have been performed for second-line options. Mycophenolate mofetil is the most widely used second-line drug, and has good efficacy particularly for patients intolerant to azathioprine, but has the major disadvantage of being teratogenic. Only few and heterogeneous data on cyclosporine, tacrolimus, everolimus and sirolimus are available. More recently, experience with the anti-tumour necrosis factor-alpha infliximab and the anti-CD20 rituximab has been published, with ambivalent results; these agents may have severe side-effects and their use should be restricted to specialized centres. Clinical trials with new therapeutic options are ongoing.

Abstract
We are reporting a rare case of acute liver injury that developed after an internal hemorrhoid treatment with the aluminum potassium sulfate and tannic acid (ALTA) regimen. A 41-year-old man developed a fever and liver injury after undergoing internal hemorrhoid treatment with a submucosal injection of ALTA with lidocaine. The acute liver injury was classified clinically as hepatocellular and pathologically as cholestastic. We could not classify the mechanism of injury. High eosinophil and immunoglobulin E levels characterized the injury, and a drug lymphocyte stimulation test was negative on postoperative day 25. Fluid replacement for two weeks after hospitalization improved the liver injury. ALTA therapy involves injecting chemicals into the submucosa, from the rectum to the anus, and this is the first description of a case that developed a severe liver disorder after this treatment; hence, an analysis of future cases as they accumulate is desirable.

Abstract
AIM To determine the diagnostic accuracy of two-dimensional shear wave elastography (2D-SWE) for the non-invasive assessment of liver fibrosis in patients with autoimmune liver diseases (AILD) using liver biopsy as the reference standard.
METHODS Patients with AILD who underwent liver biopsy and 2D-SWE were consecutively enrolled. Receiver operating characteristic (ROC) curves were constructed to assess the overall accuracy and to identify optimal cut-off values.
RESULTS The characteristics of the diagnostic performance were determined for 114 patients with AILD. The areas under the ROC curves for significant fibrosis, severe fibrosis, and cirrhosis were 0.85, 0.85, and 0.86, respectively, and the optimal cut-off values associated with significant fibrosis (≥ F2), severe fibrosis (≥ F3), and cirrhosis (F4) were 9.7 kPa, 13.2 kPa and 16.3 kPa, respectively. 2D-SWE showed sensitivity values of 81.7% for significant fibrosis, 83.0% for severe fibrosis, and 87.0% for cirrhosis, and the respective specificity values were 81.3%, 74.6%, and 80.2%. The overall concordance rate of the liver stiffness measurements obtained using 2D-SWE vs fibrosis stages was 53.5%.
CONCLUSION 2D-SWE showed promising diagnostic performance for assessing liver fibrosis stages and exhibited high cut-off values in patients with AILD. Low overall concordance rate was observed in the liver stiffness measurements obtained using 2D-SWE vs fibrosis stages.

Abstract
Background Several years ago the International Autoimmune Hepatitis Group simplified the previous revised original scoring system for diagnosis of autoimmune hepatitis (AIH) into a scoring system based on only four instead of 13 parameters. Objective We aimed to evaluate the suitability of the simplified AIH score for diagnosis of AIH in a German cohort with chronic liver diseases. Methods In this retrospective single-center study, we compared the accuracy of both AIH scores in 70 patients with AIH and 211 patients with chronic liver diseases (PBC (n = 52), PSC (n = 27), NASH (n = 67), DILI (n = 15), CHB/C (n = 50)). Sensitivity, specificity and predictability of each scoring system were calculated. Results Using the simplified AIH score, the sensitivity and specificity of detecting a probable AIH (scores ≥ 6) were 96% and 97% with a positive and negative predictive value of 92% and 99%, respectively. For diagnosis of definite AIH (scores ≥ 7), the sensitivity and specificity were 43% and 100% with a positive and negative predictive value of 97% and 84%, respectively. The concordance with the revised original criteria was 63%. The specificity for excluding AIH was excellent in both scoring system. Conclusion The simplified diagnostic criteria allow a reliable diagnosis of AIH in a German cohort.

Autoimmune hepatitis: review of histologic features included in the simplified criteria proposed by the international autoimmune hepatitis group and proposal for new histologic criteria. Mod Pathol 2017; 30:773-783. [PMID: 28106105 DOI: 10.1038/modpathol.2016.267] [Citation(s) in RCA: 66] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2016] [Revised: 12/17/2016] [Accepted: 12/19/2016] [Indexed: 12/20/2022]
Abstract
Simplified criteria for diagnosis of autoimmune hepatitis are based on autoantibodies, serum immunoglobulin G, histologic features, and negative viral serology. A score of 6 points is necessary for the designation of probable autoimmune hepatitis and 7 points or more for definite autoimmune hepatitis. The presence of three histologic features is required for categorizing a case as typical (2 points): interface hepatitis with portal lymphocytic/lymphoplasmacytic cells extending into lobule, emperipolesis, and rosettes. In the absence of all three features, a chronic hepatitis picture is considered compatible with autoimmune hepatitis (1 point). This study examines the validity of these histologic features for the diagnosis of autoimmune hepatitis. Clinical data and liver biopsies were reviewed for 88 autoimmune hepatitis, 20 primary biliary cholangitis, and 13 non-autoimmune acute hepatitis cases. Interface/lobular activity, number of plasma cells, copper/CK7 stains, and presence/absence of biliary features were assessed in autoimmune hepatitis and primary biliary cholangitis cases. The simplified criteria score was calculated. Modified histologic criteria were formulated on the basis of interface/lobular activity, number of plasma cells, and presence/absence of biliary features. Using the proposed histologic features, histologic score of 2 increased from 8 to 77%, while total simplified score of >6 increased from 69 to 86%. There was no increase in total simplified score for primary biliary cholangitis or non-autoimmune acute hepatitis. Rosettes and emperipolesis are difficult to interpret, and lack sensitivity and sensitivity for autoimmune hepatitis diagnosis. The current histologic criteria used in the current simplified score lead to underscoring of autoimmune hepatitis cases. The modified histologic criteria based on the inflammatory activity, extent of plasma cells, and results of copper/CK7 staining increased the histologic score in autoimmune hepatitis and led to a probable/definite diagnosis of autoimmune hepatitis in 17% of cases that would have otherwise been classified as non- autoimmune hepatitis by simplified score.

Abstract
OBJECTIVE Hashimoto's thyroiditis (HT), the most common autoimmune thyroid disease at any age, is often associated with other autoimmune diseases. The present study was aimed to describe the type and frequency of non-thyroidal autoimmune diseases (NTADs) in HT patients and to delineate the clinical pattern of diseases clustering in pediatric/adolescent and adult age. DESIGN Cross-sectional study. METHODS 1053 newly diagnosed HT patients (500 adults (467 F, mean age 40.2 ± 13.7 years) and 553 children/adolescents (449 F, mean age 11.1 ± 3.0 years)) were evaluated for common NTADs by means of careful recording of medical history, physical examination and assessment of selected autoantibody profiles. RESULTS The prevalence of associated NTADs was significantly higher in adults than that in pediatric/adolescent HT patients (P < .0001). In addition, the number of adult patients suffering from two or more associated NTADs was significantly higher than that of children/adolescent (P < 0.0001). A female prevalence was evident in both cohorts, but was significant in the adults (P < 0.0001). The epidemiological distribution of NTADs was strongly different in the two cohorts, the most frequent associated diseases being arthropathies and connective tissue diseases in adults and type 1 diabetes and coeliac disease in children/adolescents. Skin diseases were represented with similar prevalence in both cohorts, vitiligo being the most common. CONCLUSIONS Age at HT presentation may influence autoimmune diseases clustering, favoring the association of specific NTADs in different ages of life. Moreover, the association between HT and NTADs increases with age and occurs most frequently in adults.

Abstract
Background: The long-term outcomes of patients with autoimmune hepatitis (AIH) given the immunosuppressive treatment are considered to be preferable. However, little is known about the response of AIH patients with cirrhosis to immunosuppressive treatment. We assessed the effects of immunosuppressive therapy in Chinese AIH patients with cirrhosis from a tertiary hospital. Methods: Patients with a clinical diagnosis of AIH January 2000 and December 2015 were retrospectively reviewed. Two-hundred and fourteen patients who were followed up and satisfied the simplified AIH criteria were included in the study. Among these patients, 87 presented with cirrhosis when initially diagnosed for AIH. Immunosuppressive treatments were employed in 57 AIH patients who did not present with cirrhosis and 39 patients who presented with cirrhosis. Initial responses to immunosuppressive treatment of patients with and without cirrhosis were analyzed. Independent risk factors were assessed for predicting the prognosis of patients. The t-test and Cox regression statistical analysis were used. Results: In total, 96 AIH patients including 39 with cirrhosis and 57 without cirrhosis underwent immunosuppressive therapy. The overall complete remission after initial immunosuppressive treatment was achieved in 81/96 patients (84.4%), whereas 9/96 (9.4%) achieved incomplete response, and 6/96 (6.3%) occurred treatment failure. Compared to noncirrhotic patients, patients who presented with cirrhosis responded to treatment to a comparable extent regarding complete response (noncirrhosis 50/57 [87.7%] vs. cirrhosis 31/39 [79.5%], P = 0.275), incomplete remission (noncirrhosis 4/57 [7.0%] vs. cirrhosis 5/39 [12.8%], P = 0.338), and treatment failure (noncirrhosis 3/57 [5.3%] vs. cirrhosis 3/39 [7.7%], P = 0.629). Importantly, the remission rate was comparable (54/57 [94.7%] and 36/39 [92.3%], P = 0.629) for noncirrhotic and cirrhotic patients after immunosuppressive therapy. Compared to patients who maintained remission (n = 19) after drug withdrawal, patients who experienced relapse (n = 17) had significantly higher levels of serum immunoglobulin G at entry (15.0 ± 6.5 g/L vs. 22.3 ± 5.8 g/L, t = 2.814, P = 0.004). Moreover, cirrhosis at presentation significantly increased the risk of disease exacerbation (hazard ratio [HR]: 4.603; P = 0.002). The treatment of immunosuppressant (HR: 0.058; P = 0.005) and the level of aspartate aminotransferase at presentation (HR: 1.002; P = 0.017) also increased the risk of disease progression. Conclusions: The efficacy of initial immunosuppressive treatment in AIH patients with cirrhosis is comparable to that in those without cirrhosis. Cirrhotic patients not treated by immunosuppressants have poor long-term outcomes.

Abstract
Autoimmune liver disease (AILD) includes autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis, and overlap syndromes. AILD is the main inducing factor for late chronic liver failure, and in Western countries it is also one of the major liver diseases for which orthotopic liver transplantation is performed. In recent years, with the increasing incidence of AILD in both China and other countries, clinicians have paid more and more attention to AILD. Further standardization of diagnostic criteria for AILD has become a new hot research topic, and experts and scholars have put forward some corresponding opinions. This article describes the latest advances in the diagnosis of AILD.

Abstract
Autoimmune hepatitis (AIH) is a severe life-threatening hepatopathy of unknown etiology, affecting both pediatric and adult populations, and characterised by inflammatory liver histology, circulating non-organ-specific autoantibodies, and hypergammaglobulinaemia. AIH is a very heterogeneous disease with a variety of clinical presentations, ranging from asymptomatic liver test abnormalities to acute severe hepatitis or even acute liver failure. It responds very well to immunosuppressive treatment with prednisolone with or without azathioprine. Patients who are intolerant or fail to respond to standard therapy are candidates for alternative immunosuppressive regimens, the combination of steroids with mycophenolate mofetil or calcineurin inhibitors being the most frequently reported. The pathogenesis of AIH remains not completely understood, although there is evidence that genetic predisposition, molecular mimicry and defective immunoregulatory mechanisms contribute to the autoimmune liver damage. Areas covered: A literature search was conducted using the key-words 'autoimmune hepatitis', 'immunogenetics', 'regulatory T-cells' and 'immunosuppression'. The aim of this review is to discuss recent breakthroughs in the understanding AIH pathogenesis, diagnosis and treatment. Expert commentary: Progress in the understanding of AIH pathogenesis is likely to contribute to the development of novel therapeutic strategies, such as the adoptive transfer of autologous expanded antigen-specific regulatory T-cells.

Abstract
During the 25th annual meeting of the Asia-Pacific Association for the Study of the Liver (APASL 2016) in Tokyo, we organized and moderated an inaugural satellite symposium on the autoimmune liver diseases, autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC). Following the keynote lecture by John M. Vierling (USA), speakers from the Asia-Pacific region provided an up-to-date perspective on the epidemiology, clinical practice and research in AIH and PBC in the Asia-Pacific region. Although epidemiology and clinical features of AIH seem to be similar in East Asia compared to those in western countries, the majority of patients with AIH are detected at an advanced stage and have higher mortality rates in South Asia, indicating an unmet need for earlier diagnosis and the initiation of appropriate immunosuppressive treatment. PBC is more commonly seen in Australia and East Asia. As of 2016, clinical practice guidelines (CPG) for PBC have been published in Japan and China. Ursodeoxycholic acid (UDCA) is recommended as a first-line therapy by both CPG. Nevertheless, one of the unmet therapeutic needs in PBC is the treatment of patients refractory to or intolerant of UDCA. It is of interest that the prevalence of chronic hepatitis B (CHB) in PBC patients was low in Taiwan and mainland China where the prevalence of CHB is very high. In this review, we overview this exciting and epoch-making symposium.

Abstract
To provide an update of the latest trends in epidemiology, clinical course, diagnostics, complications and treatment of auto immune hepatitis (AIH). A search of the MEDLINE database was performed using the search terms: “auto immune hepatitis”, “clinical presentation”, “symptoms”, “signs”, “diagnosis”, “auto antibodies”, “laboratory values”, “serology”, “histopathology”, “histology”, “genetics”, “HLA genes”, “non-HLA genes”, “environment”, “epidemiology”, “prevalence”, “incidence”, “demographics”, “complications”, “HCC”, “PBC”, “PSC”, “corticosteroid”, “therapy”, “treatment”, “alternative treatment”. English-language full-text articles and abstracts were considered. Articles included reviews, meta-analysis, prospective retrospective studies. No publication date restrictions were applied. AIH is an immune meditated progressive inflammatory liver disease that predominantly affects middle-aged females but may affect people of all ages. The clinical spectrum of AIH is wide, ranging from absent or mild symptoms to fulminant hepatic failure. The aetiology of AIH is still unknown, but is believed to occur as the consequence of an aberrant immune response towards an un-known trigger in a genetically susceptible host. In the absence of a gold standard, diagnosis is based on the combination of clinical, biochemical and histopathological criteria. Immunosuppressive treatment has been the cornerstone of treatment since the earliest description of the disease in 1950 by Waldenström. Such treatment is often successful at inducing remission and generally leads to normal life expectancy. Nevertheless, there remain significant areas of unmet aetiological a clinical needs including fundamental insight in disease pathogenesis, optimal therapy, duration of treatment and treatment alternatives in those patients unresponsive to standard treatment regimens.

Abstract
Emperipolesis has been widely described in patients with autoimmune hepatitis, but the significance and the diagnostic value have not been quantitated. The goal of this study was to define the features and clinical significance of emperipolesis in autoimmune hepatitis (AIH). A retrospective histological evaluation of 101 patients with AIH and 184 controls was performed. Confocal staining for CD4, CD8, CD19, CD56, CD163, and CD11b, CK8/18 and cleaved caspase-3 was performed. Emperipolesis was observed in 65.3 % of the patients with AIH in haematoxylin and eosin (H&E)-stained slides, which was significantly higher than in patients with primary biliary cirrhosis (17.9 %), chronic hepatitis B (14.9 %), and drug-induced liver injury (25.6 %). Among AIH patients, the patients with emperipolesis had significantly higher serum (alanine aminotransferase/aspartate aminotransferase [ALT/AST]) levels. Histologically, emperipolesis was associated with more severe necroinflammatory features and more advanced fibrosis. The lymphocytes in hepatocytes were predominantly as CD8 T cells. Emperipolesis of CD8 T cells induced cleaved caspase-3 expression, and was prominent in areas apoptosis. Emperipolesis is a characteristic feature of AIH which is often seen in conjunction with interface hepatitis, plasmacytic infiltration and hepatocyte rosetting and is associated with more severe necroinflammatory and fibrotic changes. In AIH, emperipolesis is predominantly mediated by CD8 T cells, appears to induce apoptosis and may be another mechanism of autoimmune-mediated hepatocyte injury.

Abstract
Autoimmune hepatitis (AIH) fulfills the generally accepted contemporary criteria of an autoimmune liver disease: the presence of autoantibodies and autoreactive T cells, a female gender bias, association with other autoimmune diseases, response to immunosuppressive therapy and strong associations with the major histocompatibility complex HLA loci. It occurs worldwide in both children and adults and is marked by both etiopathogenic and clinical heterogeneity, differing from the other putative autoimmune liver diseases, primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC), albeit occasionally presenting with overlapping features of PBC or PSC. Although diagnostic criteria have been established and validated, there are still major issues to be clarified due to its variability, such as autoantibody-negative AIH, drug-induced AIH, AIH sharing features with PBC or PSC, and post-transplant de novo AIH. In view of the diverse presentations and courses, including classical chronic onset, acute and acute severe onset, cirrhosis and decompensated cirrhosis, individualized management of patients is indicated. Each patient should receive a personalized analysis of the benefits and side effect risks of drugs. Herein we describe a comprehensive review of the clinical phenotypes of AIH underscoring its clinical heterogeneity.

Abstract
Autoimmune hepatitis (AIH) is a complex multifactorial liver disease with unknown etiology. It may be induced by certain triggers that cause immune disorders and autoimmune attack in genetically susceptible individuals, which ultimately results in chronic persistent interface inflammation of the liver. The diagnosis of AIH is made based on comprehensive evaluation score system. All AIH patients should receive interventions and the mainstay therapy is prednisone alone or in combination with azathioprine. Further exploratory researches on refractory AIH have been developed. Liver transplantation is still the only effective option for patients with decompensated cirrhosis or hepatic failure.

Abstract
Autoimmune hepatitis (AIH) is an inflammatory liver disease with diverse clinical spectrum, which predominantly affects females. This review provides detailed comparisons of epidemiology, genetic predispositions, clinical features, risk factors of hepatocellular carcinoma, and mortality in AIH patients between eastern and western countries. AIH prevalence and incidence are lower in Asia-Pacific area than in Europe and America. European and American patients seem to have more severe disease, characterized with human leukocyte antigen-DR3 haplotype, younger age, more AIH-induced "cirrhosis" at diagnosis, higher elevated serum immunoglobulin G levels, and positive rate of antisoluble liver antigen/liver pancreatitis. The overall AIH diagnostic accuracy of revised original criteria and simplified scoring system are similar in European/American populations and Asian. Cirrhosis at presentation and non-response to immunosuppressive therapy within 1 year are the most important predictors for poor prognosis of AIH patients.

Abstract
Autoimmune hepatitis (AIH), a liver disorder affecting both children and adults, is characterized by inflammatory liver histology, elevated transaminase levels, circulating nonorganspecific autoantibodies, and increased levels of immunoglobulin G, in the absence of a known etiology. Two types of AIH are recognized according to seropositivity: smooth muscle antibody and/or antinuclear antibody define AIH type 1 and antibodies to liver-kidney microsome type 1 and/or liver cytosol type 1 define AIH type 2. AIH type 1 affects both adults and children, while AIH type 2 is mainly a paediatric disease, though it does occasionally affects young adults. AIH should be considered during the diagnostic workup of any patient with increased liver enzyme levels. AIH is exquisitely responsive to immunosuppressive treatment with prednisolone with or without azathioprine, with symptom free long-term survival for the majority of patients. For those who do not respond to standard treatment, or who are difficult-to-treat, mycophenolate mofetil and, in the absence of a response, calcineurin inhibitors should be tried in addition to steroids. The pathogenesis of AIH is not fully understood, although there is mounting evidence that genetic susceptibility, molecular mimicry and impaired immunoregulatory networks contribute to the initiation and perpetuation of the autoimmune attack. Liver damage is thought to be mediated primarily by CD4 T-cells, although recent studies support the involvement of diverse populations, including Th17 cells. A deeper understanding of the pathogenesis of AIH is likely to contribute to the development of novel treatments, such as the adoptive transfer of autologous expanded antigenspecific regulatory T-cells, which ultimately aim at restoring tolerance to liver-derived antigens.

Abstract
AIMS In this study, we aimed to evaluate the use of typical histological features of both the revised original (1999) and simplified (2008) criteria in the diagnosis of autoimmune hepatitis (AIH) in clinical practice. METHODS AND RESULTS We performed a detailed histopathological evaluation of the pretreatment biopsies of 63 AIH patients, and used biopsies of 62 untreated chronic viral hepatitis patients [hepatitis B (n = 21) or hepatitis C (n = 41)] as a reference cohort. Biopsies were systematically reviewed for inflammation, fibrosis and the presence of interface hepatitis, plasma cells, rosettes and emperipolesis with a well-defined assessment method. AIH biopsies showed more interface hepatitis (87% versus 63%, P = 0.002), more plasma cell-rich infiltrates (48% versus 27%, P = 0.02), more rosettes (49% versus 23%, P = 0.004) and more emperipolesis (78% versus 50%, P = 0.001) than chronic viral hepatitis biopsies. Emperipolesis (P = 0.01) and rosettes (P < 0.01) were superior to plasma cells and interface hepatitis as independent predictors for AIH. Moderate to severe lymphocytic cholangitis was found in 28% of AIH patients. CONCLUSIONS Emperipolesis and rosette formation are superior histological predictors of AIH than the classic hallmark features of interface hepatitis and plasma cells. In addition, moderate to severe lymphocytic cholangitis does not preclude the diagnosis of AIH.

Abstract
OBJECTIVE To evaluate the Paris criteria, the revised diagnostic criteria and the simplified diagnostic scoring system in the diagnosis of primary biliary cirrhosis (PBC)-autoimmune hepatitis (AIH) overlap syndrome in Chinese patients. METHODS Medical records of the patients who were diagnosed with PBC at the Union Hospital and Tongji Hospital, Tongji Medical University, Huazhong University of Science and Technology (Wuhan, Hubei Province, China) from 2003 to 2012 were retrospectively reviewed. The overlap syndrome was diagnosed based on the Paris criteria, the revised criteria and the simplified criteria, respectively. Patients' clinical characteristics, laboratory examination results and histological findings were collected. The sensitivity and specificity of the three criteria for diagnosing PBC-AIH overlap syndrome were calculated. RESULTS PBC-AIH overlap syndrome was diagnosed in 2, 13 and 10 patients with PBC based on the Paris, the revised and the simplified criteria, respectively. The sensitivity and specificity of the simplified criteria in diagnosing the overlap syndrome was 90.0% and 98.2%, which were the highest among the three criteria, followed by the revised criteria. The Paris criteria showed a high specificity (100%) but a relatively low sensitivity (20.0%). In addition, some patients who did not fulfil the Paris criteria still benefited from the immunosuppressive agents. CONCLUSIONS For Chinese patients with the PBC-AIH overlap syndrome, the simplified criteria appear to be the most efficacious compared with the Paris criteria and the revised criteria. Further studies should be performed to confirm these observations with respect to long-term outcomes and therapeutic implications.

Abstract
BACKGROUND AND AIMS Epidemiological data on autoimmune hepatitis (AIH) are scarce. In this study, we determined the clinical and epidemiological characteristics of AIH patients in the Netherlands (16.7 million inhabitants). METHODS Clinical characteristics were collected from 1313 AIH patients (78% females) from 31 centers, including all eight academic centers in the Netherlands. Additional data on ethnicity, family history and symptoms were obtained by the use of a questionnaire. RESULTS The prevalence of AIH was 18.3 (95% confidential interval [CI]: 17.3-19.4) per 100,000 with an annual incidence of 1.1 (95% CI: 0.5-2) in adults. An incidence peak was found in middle-aged women. At diagnosis, 56% of patients had fibrosis and 12% cirrhosis in liver biopsy. Overall, 1% of patients developed HCC and 3% of patients underwent liver transplantation. Overlap with primary biliary cirrhosis and primary sclerosing cholangitis was found in 9% and 6%, respectively. The clinical course did not differ between Caucasian and non-Caucasian patients. Other autoimmune diseases were found in 26% of patients. Half of the patients reported persistent AIH-related symptoms despite treatment with a median treatment period of 8 years (range 1-44 years). Familial occurrence was reported in three cases. CONCLUSION This is the largest epidemiological study of AIH in a geographically defined region and demonstrates that the prevalence of AIH in the Netherlands is uncommon. Although familial occurrence of AIH is extremely rare, our twin data may point towards a genetic predisposition. The high percentage of patients with cirrhosis or fibrosis at diagnosis urges the need of more awareness for AIH.

Abstract
AIM: To analyze the etiology and pathological features of unexplained jaundice, and to evaluate the diagnostic value of liver biopsy for unexplained jaundice.
METHODS: We retrospectively analyzed the clinical symptoms and signs, biochemical and immunologic parameters, pathology and diagnosis in patients with unexplained jaundice who underwent percutaneous liver biopsy at our hospital in recent years.
RESULTS: A total of 53 patients with unexplained jaundice were included, of whom 24 had autoimmune liver disease (45.3%), 12 cases had Gilbert's syndrome (22.6%), 10 had drug-induced liver injury (18.9%), 5 had non-alcoholic fatty liver disease (9.4%), 1 had scleroderma (1.9%), and 1 had hepatic lymphoma (1.9%). The prevalence rates of autoimmune liver disease and Gilbert's syndrome had significant gender differences. Each disease had its own specific feature in pathology, and final diagnosis relied on comprehensive assessment of clinical and laboratory findings.
CONCLUSION: For patients with unexplained non-viral jaundice, autoimmune liver disease should be first considered, followed by Gilbert's syndrome and drug-induced liver injury. Ultrasound-guided percutaneous liver biopsy is an important tool for establishing a diagnosis.

Abstract
Background Antinuclear antibodies (ANA), smooth muscle antibodies (SMA) and antibodies to a soluble liver antigen/liver pancreas (anti-SLA/LP) are useful markers that can help clinicians to diagnose and classify autoimmune hepatitis (AIH). Objectives To determine whether ANA, SMA and anti-SLA/LP help to accurately diagnose patients with AIH. Search strategy The PubMed, CNKI, WANFANG, and SinoMed databases were accessed to retrieve studies published in English and Chinese. Studies published up to October 2013 were reviewed. Selection criteria Studies on the diagnostic value of ANA, SMA or anti-SLA/LP in the diagnosis of known or suspected AIH were included. Data collection and analysis Two authors evaluated studies independently and rated their methodological quality using quality assessment of diagnostic accuracy studies (QUADAS) tools; relevant data were abstracted. The random-effects method was used to summarize sensitivities, specificities, positive and negative likelihood ratios, and diagnostic odds ratios (DORs) from all 29 studies. Results The pooled sensitivity, specificity, positive and negative likelihood ratios, and DOR for ANA were 0.650 (95% confidence interval [CI], 0.619 to 0.680), 0.751 (95%CI, 0.737 to 0.764), 3.030 (95%CI, 2.349 to 3.910), 0.464 (95%CI, 0.356 to 0.604), and 7.380 (95%CI, 4.344 to 12.539), respectively. For SMA, the values were 0.593 (95%CI, 0.564 to 0.621), 0.926 (95%CI, 0.917 to 0.934), 11.740 (95%CI, 7.379 to 18.678), 0.449 (95%CI, 0.367 to 0.549), and 31.553 (95%CI, 17.147 to 58.060), respectively. Finally, for anti-SLA/LP, the values were 0.194 (95%CI, 0.168 to 0.222), 0.989 (95%CI, 0.985 to 0.993), 11.089 (95%CI, 7.601 to 16.177), 0.839 (95%CI, 0.777 to 0.905), and 16.867 (95%CI, 10.956 to 25.967), respectively. Authors’ conclusions ANA provided moderate sensitivity and specificity, while SMA gave moderate sensitivity and high specificity, and anti-SLA/LP exhibited low sensitivity and high specificity. All three antibodies were limited by their unsatisfactory sensitivities and lack of consistency.

Abstract
The aim of this study was to evaluate the simplified and revised scoring systems for the diagnosis of autoimmune hepatitis (AIH). Seventy-seven patients diagnosed with AIH via the revised scoring system were enrolled in this study. Statistical analysis was performed by means of the χ2 test and logistic regression analysis. A total of 39 patients with definite AIH and 38 patients with probable AIH were diagnosed by the revised scoring system, whereas among these 77 patients, the simplified scoring system classified nine cases as definite AIH, 39 as probable AIH and 29 without AIH. In this study, the parameters contributing to the discrepant diagnosis of AIH were compared using the revised and simplified systems. A χ2 test showed that antinuclear antibody (ANA) or smooth muscle antibody (SMA) titers were significantly lower in the patients with discrepant diagnoses (χ2=15.0, P=0.001). Logistic regression with backward selection revealed that for the discrepant diagnosis of patients, the presence of other concurrent autoimmune diseases [odds ratio (OR)=7.25; P=0.018; 95% confidence interval (CI), 1.41–37.29] was the only independent risk factor. In addition, the presence of anti-soluble liver antigen/liver-pancreas antigen (SLA/LP) or perinuclear antineutrophil cytoplasmic antibody (pANCA) (OR=0.12; P=0.022; 95% CI, 0.02–0.74), the level of immunoglobulin G (IgG) with 1–1.1 × Normal (N) (OR=0.02; P=0.044; 95% CI, 0.00–0.89) and ANA or SMA titers ≥1:80 (OR=0.04; P=<0.001; 95% CI, 0.01–0.23) were three independent protective factors. In conclusion, the revised scoring system has a superior performance in the diagnosis of patients with AIH compared with the simplified scoring system. According to the simplified scoring system, other concurrent autoimmune diseases are the risk factor for the AIH diagnosis.

Abstract
BACKGROUND Autoimmune hepatitis (AIH) is a disease of unknown aetiology characterised by interface hepatitis, hypergammaglobulinaemia, circulating autoantibodies and a favourable response to immunosuppression. AIM To review recent advancements in understanding aetiopathogenesis, clinical, serological and histological features, diagnostic criteria and treatment strategies of AIH. METHODS Published studies on AIH extracted mainly from PubMed during the last 15 years. RESULTS Autoimmune hepatitis has a global distribution affecting any age, both sexes and all ethnic groups. Clinical manifestations are variable ranging from no symptoms to severe acute hepatitis and only seldom to fulminant hepatic failure. Autoimmune attack is perpetuated, possibly via molecular mimicry mechanisms, and favoured by the impaired control of regulatory T-cells. A typical laboratory finding is hypergammaglobulinaemia with selective elevation of IgG, although in 15-25% of patients - particularly children, elderly and acute cases - IgG levels are normal. Liver histology and autoantibodies, although not pathognomonic, still remain the hallmark for diagnosis. Immunosuppressive treatment is mandatory and life-saving; however, to meet strict response criteria, the conventional therapy with prednisolone with or without azathioprine is far from ideal. CONCLUSIONS Autoimmune hepatitis remains a major diagnostic and therapeutic challenge. The clinician, the hepato-pathologist and the laboratory personnel need to become more familiar with different expressions of the disease, interpretation of liver histology and autoimmune serology. According to the strict definition of treatment response issued by the 2010 AASLD guidelines, many patients are nonresponders to conventional treatment. Newer immunosuppressive agents targeting pathogenetic mechanisms can improve patient management, which needs to be tailored on a case-by-case basis.
