Abstract
Primary sclerosing cholangitis (PSC) is a variably progressive, fibrosis-causing autoimmune disorder of the intrahepatic and extrahepatic bile ducts of unclear etiology. PSC is commonly (in 60%-90% of cases) associated with an inflammatory bowel disease (IBD) like PSC-IBD and less commonly with an autoimmune hepatitis (AIH) like PSC-AIH or AIH-overlap disorder. Hepatologists and Gastroenterologists often consider these combined conditions as distinctly different from the classical forms in isolation. Here, we review recent epidemiologic observations and highlight that PSC-IBD and PSC-AIH overlap appear to represent aspects of a common PSC clinico-pathological pathway and manifest in an age-of-presentation-dependent manner. Particularly from the pediatric experience, we hypothesize that all cases of PSC likely originate from a complex "Early PSC"-"IBD"-"AIH" overlap in which PSC defines the uniquely and variably associated "AIH" and "IBD" components along an individualized lifetime continuum. We speculate that a distinctly unique, "diverticular autoimmunity" against the embryonic cecal- and hepatic diverticulum-derived tissues may be the origin of this combined syndrome, where "AIH" and "IBD" variably commence then variably fade while PSC progresses with age. Our hypothesis provides an explanation for the age-dependent variation in the presentation and progression of PSC. This is critical for the optimal targeting of studies into PSC etiopathogenesis and emphasizes the concept of a "developmental window of opportunity for therapeutic mitigation" in what is currently recognized as an irreversible disease process. The discovery of such a window would be critically important for the targeting of interventions, both the administration of current therapies and therapeutic trial planning.

Abstract
Autoimmune hepatitis (AIH) is an inflammatory liver disease wherein the body's immune system instigates an attack on the liver, causing inflammation and hepatic impairment. This disease usually manifests in genetically predisposed individuals and is triggered by stimuli or environments such as viral infections, environmental toxins, and drugs. The causal role of COVID-19 vaccination in AIH remains uncertain. This review of 39 cases of vaccine-related AIH indicates that female patients above the age of 50 years or those with potential AIH risk factors may be susceptible to vaccine-related AIH, and the clinical features of vaccine-associated AIH are similar to those of idiopathic AIH. These features commonly manifest in patients after the first dose of vaccination, with symptom onset typically delayed by 10-14 days. The incidence of underlying liver disease in patients with potential health conditions associated to liver disease is similar to that of patients without preexisting illnesses. Steroid administration is effective in treating vaccine-related AIH-susceptible patients, with most patients experiencing improvement in their clinical symptoms. However, care should be taken to prevent bacterial infections during drug administration. Furthermore, the possible pathogenic mechanisms of vaccine-associated AIH are discussed to offer potential ideas for vaccine development and enhancement. Although the incidence of vaccine-related AIH is rare, individuals should not be deterred from receiving the COVID-19 vaccine, as the benefits of vaccination significantly outweigh the risks.

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
AIM Drug-induced liver injury (DILI) is becoming a worldwide problem with its still unexplained properties. METHODS The data of patients who were diagnosed with DILI between January 2008 and December 2013 were assessed. RESULTS Five patients had been diagnosed with intrinsic and 82 patients with idiosyncratic DILI. The most common causative agents were antimicrobial drugs. The most common injury pattern was hepatocellular. When patients with bilirubin levels of more than 5 mg/dL were divided into two groups according to receiving steroid therapy (n = 11) or not (n = 40), there was not any significant difference according to their clinical results (P > 0.05). Five of the idiosyncratic DILI patients were diagnosed with drug-induced autoimmune hepatitis (DI-AIH). In histopathological examination, hepatic rosette formation and emperipolesis were observed to be more common among patients with DI-AIH when compared with ones without (P < 0.05). Interestingly, in the remaining patients with DILI (n = 77), three of them were diagnosed with classic autoimmune hepatitis during long-term follow up (range, 11-51 months). CONCLUSION The most common causes were antimicrobials, but any agents that have not been defined to cause DILI can induce DILI. The efficacy of steroids in DILI has not been observed but all deaths were observed in the steroid-free group. The association of DILI and AIH was observed in two different types in terms of diagnosis in our study. The first association was DI-AIH. The second one is the classical AIH which developed in three patients after a few months following spontaneous recovery of DILI.

Abstract
Liver diseases in the elderly have aroused less interest than diseases of other organs, since the liver plays a limited role in aging. There are no specific liver diseases of old age, but age-related anatomical and functional modifications of the liver cause changes in the frequency and clinical behavior of some liver diseases compared with those in younger patients. This review discusses the most important features of liver function in the healthy elderly population, as well as the features of the most prevalent liver diseases in this age group, especially the diagnostic approach to the most common liver problems in the elderly: asymptomatic elevation of serum transaminases and jaundice.

Abstract
BACKGROUND In Caucasians with autoimmune hepatitis, patients with acute presentation have autoimmune thyroiditis and histological zone 3 necrosis more frequently. AIM We aimed at investigating clinical features of Japanese autoimmune hepatitis patients with acute presentation. METHODS Of 176 patients retrospectively reviewed, 53 were diagnosed with acute presentation. RESULTS Patients with acute presentation had higher serum levels of bilirubin and transaminase, lower frequencies of autoimmune thyroiditis and antinuclear antibodies of 1:160 or greater, and a higher frequency of zone 3 necrosis. Of the 53 patients with acute presentation, 10 showed histological acute hepatitis; however, advanced staging of fibrosis was found in 13 patients. In patients with acute presentation, those with histological acute hepatitis were younger than those with chronic hepatitis. The cumulative incidental rate of the normalization of serum alanine aminotransferase levels with prednisolone treatment was similar between patients with acute presentation and those with classical presentation. CONCLUSIONS In line with previous results, zone 3 necrosis is a histological characteristic of autoimmune hepatitis with acute presentation. Autoimmune hepatitis with acute presentation includes not only histological acute hepatitis but also acute exacerbation of pre-existing chronic disease. On the other hand, Japanese patients with acute presentation may also have different clinical features from Caucasian patients.

Abstract
BACKGROUND/AIMS Chronic evolution after drug-induced liver injury (DILI) has been reported. How often this leads to liver-related morbidity and mortality is unexplored. METHODS Patients who survived DILI and concomitant jaundice reported to the Swedish Adverse Drug Reaction Advisory Committee (1970-2004) were linked to the Swedish Hospital Discharge and Cause of Death Registries. RESULTS Among the 712 survivors, 27 could not be retrieved but 685 patients could be linked to the registries, 392 females (57.2%) and 293 males (42.8%) median age 58 (41-74), a mean follow-up of 10 years. A total of 23/685 (3.4%) patients had been hospitalized for liver disease and 5 had liver-related mortality. Eight patients developed cirrhosis (7 decompensated, 5 died), 5 had "cryptogenic" cirrhosis in which DILI might have played a role in this development. Duration of therapy before DILI was longer in patients with liver-related morbidity/mortality (135+/-31 days vs. 53+/-3; p<0.0001). Autoimmune hepatitis developed in 5/23 (22%), all of female gender after a mean of 5.8 years. CONCLUSIONS Development of clinically important liver disease after severe DILI associated with jaundice is rare after acute DILI. However decompensated "cryptogenic" cirrhosis developed in some patients with fatal outcome in which DILI might have played a role in this development.

Abstract
Primary biliary cirrhosis (PBC)-autoimmune hepatitis (AIH) overlap syndrome is a clinical entity characterized by the occurrence of both conditions at the same time in the same patient. In addition to PBC-AIH overlap syndrome, transitions from one autoimmune disease to another have been reported, but no systematic series have been published. We report a series of 12 patients with consecutive occurrence of PBC and AIH (i.e., PBC followed by AIH). Among 282 PBC patients, 39 were identified who fulfilled criteria for probable or definitive AIH. AIH developed in 12 patients (4.3%). The baseline characteristics of the patients were similar to those of patients with classical PBC. Time elapsed between the diagnosis of PBC and the diagnosis of AIH varied from 6 months to 13 years. Patients with multiple flares of hepatitis at the time of diagnosis of AIH had cirrhosis on liver biopsy. Ten patients were given prednisone +/- azathioprine; short-term as well as sustained remissions were obtained in 8 of these, while two had multiple relapses and eventually died 8 and 7 years after diagnosis of AIH. In conclusion, the development of superimposed AIH could not be predicted from baseline characteristics and initial response to UDCA therapy. If not detected early, superimposed AIH can result in rapid progression toward cirrhosis and liver failure in PBC patients.

Abstract
AIM To study features in older patients with autoimmune hepatitis, as this was considered mainly a disease of young females. METHODS Analysis of 28 patients diagnosed at age > or =65 years compared with 84 younger patients. RESULTS The incidence was similar at all age decades. The ratio M:F was 1:3 (> or =65 years) vs. 1:2 (<65 years). Presenting symptoms were not different when compared with younger patients and consisted of general malaise and fatigue (36%), jaundice +/- other symptoms (50%), or ascites (11%). Antinuclear antibodies (ANA) > or = 1/80 were positive in 93%, smooth muscle antibodies (SMA) > 1/40 in 50%, anti-liver kidney microsomes (anti-LKM) proved always negative. Histology showed acute necrotizing hepatitis in 19%, severe interphase hepatitis in 15%, chronic hepatitis with plasmo-lymphocytic infiltrate in 30%, cirrhosis in 29% (with active inflammation in one-third); biopsy was refused in 11%. The elderly responded very well to low doses of methylprednisolone (< or =8 mg) and azathioprine (1 mg/kg). This schedule obviates side-effects such as infections seen with higher dosages. CONCLUSION Autoimmune hepatitis has to be also looked for in the elderly with acute and chronic hepatitis. The steroid therapy should be individualized but kept at a low dose.

Abstract
The overlap syndrome raises several questions. First could these patients have two coincident autoimmune diseases? Such possibility cannot be discarded in particular in the setting of consecutive occurrence of the two conditions (eg, PBC followed by AIH) and this is consistent with the fact that autoimmune diseases are associated with one another in about 5% to 10% of cases. Furthermore, it is presumed that they share similar genetic susceptibility. A second possibility could be that overlap syndrome represents the middle of a continuous spectrum of two autoimmune liver diseases. The systematic study of the relationships between elementary histologic lesions and biochemistries in "pure" PBC patients pleads strongly for such a hypothesis. Pure PBC is characterized by 2 different groups of elementary lesions that are not interrelated: first, florid bile duct lesions and bile duct paucity and second, lymphocytic piecemeal necrosis and lobular necro-inflammatory changes. Furthermore, the first set of lesions is selectively associated with biochemical cholestasis and IgM levels, whereas the second set of lesions is selectively associated with serum transaminase activities and IgG levels. These observations are consistent with the assumption that two main mechanisms are involved in the progression of liver injury in PBC. The first is bile duct destruction leading to chronic cholestasis and fibrosis of biliary pattern. The second is lymphocytic piecemeal necrosis of hepatocytes, which tends to lead to cirrhosis, the pattern of which resembles cirrhosis following various forms of chronic active hepatitis. The author has therefore speculated that the picture of pure PBC results always forms the clinical and biochemical expression of the two main histologic lesions, and combination of these processes might explain why the spectrum of PBC varies from typical PBC to AIH or PBC overlap. A third hypothesis is that an exaggerated hepatitic response in PBC is associated with the HLA haplotype commonly seen in AIH, eg, B8, DR3, DR4. Further studies are obviously needed to confirm such an attractive hypothesis. Other possible explanation for the concurrent occurrence of features of both conditions in the same individual includes the selective modulation of HLA class 1, class 2 expression and Rantes by cholestasis itself and in particular bile acids. It is conceivable that the degree of interface and lobular inflammation in PBC and PSC may be modulated by chemokines, their receptors, and the parenchymal concentrations of individual bile acids that are all, at least in part, genetically determined.
