Abstract
Disease recurrence after liver transplantation (LT) is common. Certain liver diseases such as autoimmune hepatitis and steatotic liver disease may appear de novo after LT. This review discusses post LT alcohol-associated liver disease, metabolic dysfunction-associated liver disease, autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis. Both recurrent and de novo diseases are important causes of allograft failure.

Abstract
The distinction between autoimmune and alloimmune reactions in liver transplant recipients can be challenging. Plasma cell-rich rejection (PCRR), previously known as de novo autoimmune hepatitis or plasma cell hepatitis, is an atypical and underrecognized form of allograft rejection observed post-liver transplantation, often in conjunction with features of T cell-mediated and antibody-mediated rejection. If PCRR is not recognized and treated with prompt immunosuppressive augmentation, patients can develop advanced hepatic fibrosis, necroinflammation, and allograft failure. Given the significant morbidity and mortality associated with PCRR, there exists a need to develop noninvasive biomarkers which can be used in screening, diagnosis, and treatment monitoring of PCRR. This study is a literature review of candidate serum-based and tissue-based biomarkers in adult and pediatric liver transplant PCRR. We also discuss biomarkers from plasma cell-rich processes observed in other disease states and other organ transplant recipients that might be tested in liver transplant PCRR. We conclude with proposed future directions in which biomarker implementation into clinical practice could lead to advances in personalized management of PCRR.

Abstract
Autoimmune liver diseases (AILDs) are a group of conditions where immune-mediated liver damage can lead to the need for transplantation. Collectively, they account for almost a quarter of all liver transplants. Outcomes in terms of graft and patient survival for all liver transplants have improved markedly over decades with improvements in patient selection, surgical techniques and longer-term care and this is also seen in patients with AILDs. The current five- and ten-year survival rates post-transplant in autoimmune disease are excellent, at 88% and 78%, respectively. A key factor in maintaining good outcomes post liver transplant for these autoimmune conditions is the immunosuppression strategy. These patients have increased the rates of rejection, and autoimmune conditions can all recur in the graft ranging from 12 to 60% depending on the population studied. Immunosuppressive regimens are centred on calcineurin inhibitors, often combined with low dose corticosteroids, with or without the addition of antimetabolite therapy. There is no clear evidence-based immunosuppressive regimen for these conditions, and a tailored approach balancing the individuals' immunological profile against the risks of immunosuppression is often used. There are disease-specific considerations to optimised graft function including the role of ursodeoxycholic acid in both primary biliary cholangitis and primary sclerosing cholangitis and the role and timing of colectomy in primary sclerosing cholangitis in inflammatory bowel disease patients. However, unmet needs still exist in the management of AILDs post liver transplantation particularly in building the evidence base for optimal immunosuppression as well as mitigating the risk of recurrent disease.

Abstract
Autoimmune hepatitis (AIH), post-transplant recurrent AIH (rAIH), and plasma cell-rich rejection (PCR) are clinical diagnoses with the shared histopathologic hallmark of plasma cell hepatitis (PCH). As these histologically and serologically indistinguishable diagnoses are differentiated by clinical context, it remains uncertain whether they represent distinct immunologic phenomena. Improved understanding of immunoglobulin subclass 4-producing plasma cells (IgG4-PC) has brought attention to IgG4 as an immunophenotypic biomarker. To date, degree and clinical significance of IgG4-PC infiltration in PCH remain elusive. This retrospective, single-center study assessed IgG4-PC infiltration in AIH, rAIH, and PCR via standardized immunohistochemistry analysis. Identified cases from 2005 to 2020 (n = 47) included AIH (treatment-naïve AIH (tnAIH): n = 15 and AIH-flare on treatment (fAIH); n = 10), rAIH (n = 8), and PCR (n = 14) were analyzed and correlated with clinical characteristics. IgG4-Positivity (# IgG4-PC/# pan-IgG-expressing cells) distribution was heterogenous and overlapping [tnAIH: 0.060 (IQR 0.040-0.079), fAIH: 0.000 (0.000-0.033), rAIH: 0.000 (0.000-0.035), PCR: 0.228 (0.039-0.558)]. IgG4-Positivity was inversely correlated with corticosteroid use (p < 0.001). IgG4-Positivity ≥0.500 was associated with rapid AST improvement (p = 0.03). The variable IgG4-Positivity of AIH, rAIH and PCR suggests diverse and overlapping immunopathologic mechanisms and that current diagnostic schemes inadequately capture PCH immunopathology. We propose incorporation of IgG4-Positivity to refine current PCH classification and treatment strategies.

Abstract
Extended survival of liver transplant recipients has brought rejection management to the forefront of liver transplant research. This article discusses T-cell-mediated rejection, antibody-mediated rejection, and chronic rejection. We focus on the prevention and then discuss treatment options. Future directions of rejection management include biomarkers of rejection, which may allow for monitoring of patients who are considered high risk for rejection and detection of rejection before there is any clinical evidence to improve graft and patient survival. With improved graft life and survival of liver transplant recipients, the new frontier of rejection management focuses on immunosuppression minimization, withdrawal, and personalization.

Abstract
Decompensated cirrhosis due to nonalcoholic steatohepatitis (NASH), and autoimmune liver diseases (AILD) are the most common indications for liver transplantation (LT). AILD include autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC). NASH and AILD share some peculiarities as they can recur in the new graft, compromising the quality of life, and graft and patient survival. De novo NASH or AIH connotes the development of these liver diseases in patients transplanted for other indications. The diagnosis of recurrent or de novo liver disease usually requires a liver biopsy aside from recurrent PSC, which can be diagnosed with compatible imaging studies and exclusion of other causes of biliary strictures. The treatment of recurrent NASH is lifestyle modifications aiming for weight loss. Recurrent and de novo AIH is usually treated with corticosteroids with or without azathioprine. Recurrent PBC should be treated with ursodeoxycholic acid. There are no proven treatment options for recurrent PSC. Patients with graft failure should be considered for repeat LT. Future investigations should use standardized diagnostic criteria for each disease, seek diagnostic biomarkers, and evaluate treatments that improve outcomes.

Abstract
Autoimmune hepatitis (AIH) is a severe liver disease that arises in genetically predisposed male and female individuals worldwide. Diagnosis of AIH is made clinically applying diagnostic scores; however, the heterotopic disease phenotype often makes a rapid determination of disease challenging. AIH responds favorably to steroids and pharmacologic immunosuppression, and liver transplantation is only necessary in cases with acute liver failure or end-stage liver cirrhosis. Recurrence or development of de novo AIH after transplantation is possible, and treatment is similar to standard AIH therapy. Current experimental investigations of T cell-mediated autoimmune pathways and analysis of changes within the intestinal microbiome might advance our knowledge on the pathogenesis of AIH and trigger a spark of hope for novel therapeutic strategies.

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
Clinical indications for liver transplantation (LT) in patients with autoimmune hepatitis (AIH) are identical to those of patients with other chronic liver diseases that end in acute or semiacute liver failure, decompensated cirrhosis, or hepatocellular carcinoma. Recurrent disease after LT has been reported in 10%-50% of patients with AIH, and the frequency of detection is influenced in part by the use of protocol or clinically indicated liver biopsy. De novo AIH connotes the development of AIH in patients transplanted for liver diseases other than AIH, and it has been reported in 5%-10% of pediatric and 1%-2% of adult recipients. Recurrent disease can negatively impact on graft and patient survival, and retransplantation has been required in 8%-23%. De novo AIH is within the spectrum of graft dysfunction that includes plasma cell-rich rejection, and it can also progress to cirrhosis and graft failure. Treatment for recurrent or de novo disease is based on the conventional regimens for AIH, and corticosteroid therapy alone or combined with azathioprine is standard. Better control of disease activity prior to LT has been associated with less recurrence, and maintenance corticosteroid treatment after LT can reduce its frequency. In conclusion, recurrent AIH is far more frequent than de novo AIH. Both may have negative impacts on graft and patient survival, and early detection and treatment are key objectives. Future investigations must codify the diagnostic criteria for each graft dysfunction, seek diagnostic biomarkers, and evaluate treatments that improve outcomes without increasing the risk of pre- and post-LT infections.

Abstract
Antibody-mediated rejection (AMR) in liver transplantation has long been underestimated. The concept of the liver as an organ susceptible to AMR has emerged in recent years, not only in the context of the major histocompatibility complex with the presence of HLA donor-specific antibodies, but also with antigens regarded as “minor”, whose role in AMR has been demonstrated. Among them, antibodies against glutathione S-transferase T1 have been found in 100% of patients with de novo autoimmune hepatitis (dnAIH) when studied. In its latest update, the Banff Working Group for liver allograft pathology proposed replacing the term dnAIH with plasma cell (PC)-rich rejection. Antibodies to glutathione S-transferase T1 (GSTT1) in null recipients of GSTT1 positive donors have been included as a contributory but nonessential feature of the diagnosis of PC-rich rejection. Also in this update, non-organ-specific anti-nuclear or smooth muscle autoantibodies are no longer included as diagnostic criteria. Although initially found in a proportion of patients with PC-rich rejection, the presence of autoantibodies is misleading since they are not disease-specific and appear in many different contexts as bystanders. The cellular types and proportions of the inflammatory infiltrates in diagnostic biopsies have been studied in detail very recently. PC-rich rejection biopsies present a characteristic cellular profile with a predominance of T lymphocytes and a high proportion of PCs, close to 30%, of which 16.48% are IgG4+. New data on the relevance of GSTT1-specific T lymphocytes to PC-rich rejection will be discussed in this review.

Abstract
Paediatric autoimmune liver disease is characterized by inflammatory liver histology, circulating autoantibodies, and increased levels of IgG, in the absence of a known etiology. Three conditions have a likely autoimmune pathogenesis: autoimmune hepatitis (AIH), autoimmune sclerosing cholangitis, and de novo AIH after liver transplantation. Two types of pediatric AIH are recognized according to seropositivity for smooth muscle and/or antinuclear antibody (AIH-1) or liver kidney microsomal type 1 and/or anti-liver cytosol type 1 antibodies (AIH-2).Pertinent issues addressing the diagnosis, treatment, and long-term follow-up were formulated by a core group of ESPGHAN members. They have commissioned the first authors with execution of this project. Initially, they have performed a systematic literature search on MEDLINE, ResearchGate, and Mendeley databases during the last 30 years and produced a document focusing on prospective and retrospective studies in children. The ESPGHAN core group and ESPGHAN Hepatology Committee members voted on each recommendation, using a formal voting technique.

Autoantibodies against CYP-2C19: A Novel Serum Marker in Pediatric De Novo Autoimmune Hepatitis? BIOMED RESEARCH INTERNATIONAL 2017; 2017:3563278. [PMID: 29279846 PMCID: PMC5723963 DOI: 10.1155/2017/3563278] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/11/2017] [Revised: 10/31/2017] [Accepted: 11/06/2017] [Indexed: 11/19/2022]
Abstract
Diagnosis of de novo autoimmune hepatitis (AIH) after orthotopic liver transplantation (OLT) is challenging especially in the absence of hyper-γ-globulinemia. Circulating autoantibodies are not sensitive nor specific in de novo AIH but when positive increase the diagnostic probability. We report the discovery of novel liver microsomal (LM) autoantibodies against CYP-2C19 in a 9-year-old boy with “de novo” AIH developed 7 years after OLT. Graft dysfunction presented with hypertransaminasemia (up to 400 IU/L), while serum γ-globulins remained within the normal range for age. Liver histology and response to high dose prednisone (2 mg/kg/day) with the addition of azathioprine therapy further supported the diagnosis of de novo AIH. Autoantibodies investigation by indirect immunofluorescence (IF) on rodent tissues showed a novel staining pattern involving the pericentral liver zone and sparing the renal tissue. Human but not rat liver proteins immunoblotting allowed us to characterize the novel LM antibodies and to identify CYP-2C19 as human antigen. The finding offers insights into the controversial discussion about autoimmunity versus alloreactivity with regard to the pathogenesis of de novo AIH. Correct information on human versus rat tissue antigens tested by methods other than IF for antibodies detection may have significant implications for the correct diagnosis and management of patients followed up after OLT.

Abstract
The long-term course and outcome of DAIH is unknown. A retrospective multicenter study assessing associations and long-term consequences of DAIH developing in a transplanted allograft is presented. Children with DAIH were followed from diagnosis until death, re-LT, or transfer of care and for a minimum of 1 year. A total of 31 patients of 1833 (1.7%) LT were identified; 29 followed for a median of 7.1 years (range, 1.6-15); 52% had no rejection preceding diagnosis of DAIH. Transaminases fell following treatment with steroids and antimetabolites (ALT 108 vs 39 U/L (P=.002); AST 112 vs 52 U/L (P=.003); GGT 72 vs 36 U/L (P=.03), but this was not universally sustained. Transaminases >2X ULN observed in 38% of patients at last follow-up; commonly GGT, attributed to bile duct injury and ductopenia. Portal hypertension (PHT) was seen in four patients and associated with severe fibrosis and cirrhosis. Re-LT occurred in two patients for chronic rejection (CR) and uncontrolled PHT with gastrointestinal bleeding, respectively. No deaths from DAIH were reported. DAIH is an uncommon complication following pediatric LT requiring prolonged and augmented immunosuppression. It is associated with continued allograft dysfunction and may lead to bile duct injury, CR, and PHT necessitating re-LT.

Impact of Antibodies That React With Liver Tissue and Donor-Specific Anti-HLA Antibodies in Pediatric Idiopathic Posttransplantation Hepatitis. Transplantation 2017; 101:1074-1083.

Abstract
Background The cause of late graft dysfunction has not been elucidated. Although an antibody-mediated reaction is suspected as a potential mechanism, the target antigens have not been clarified. Methods To clarify the etiology of idiopathic posttransplantation hepatitis (IPTH), we simultaneously examined the presence of antibodies that react with liver tissue (ARLT) by means of indirect immunofluorescence staining, as well as the presence of donor-specific anti-human leukocyte antigen antibodies (HLA-DSA). A subanalysis of the IPTH group was also performed. Within the IPTH group, the correlation between ARLT titer and clinical data were analyzed. Results In the sera of patients with IPTH (30 patients), ARLT were found at a significantly higher frequency than in patients without IPTH (42 patients; P < 0.001). Moreover, the ARLT titer appeared to be correlated with the severity of hepatitis or hepatic injury. In contrast, the frequency of HLA-DSA was significantly lower in patients with IPTH than in patients without IPTH (P = 0.001). Conclusion Our findings indicate that ARLT, and not HLA-DSA, profoundly influence the etiology of IPTH. The authors show that antibodies that react with liver tissue and not donor-specific anti-human leukocyte antigen antibodies, profoundly influence the etiology of idiopathic posttransplantation hepatitis in children providing a rationale for therapy.

Abstract
Recurrent autoimmune hepatitis (AIH) and de novo AIH are 2 important causes of late graft failure after liver transplantation (LT). Recurrent AIH occurs in patients who undergo LT for AIH. De novo AIH occurs in patients who are transplanted for etiologies other than AIH. Although typically treated with standard treatment for AIH, including corticosteroids and azathioprine, both recurrent and de novo AIH may progress to end-stage liver disease requiring retransplantation.

Lack of Clinical Relevance of ANA and ASMA Positivity in Patients with Liver Transplantation without a History of Autoimmune Diseases. BIOMED RESEARCH INTERNATIONAL 2017; 2017:2456916.

Abstract
The relevance of isolated autoimmunity elevation in orthotopic liver transplantation (OLT) patients is unknown. Our aim was to analyse how serum autoantibodies change in time and to evaluate their clinical relevance in OLT patients. Patients were invited to provide samples to evaluate ANA, AMA, ASMA, and LKM at the time of enrolment (T0), after 6 months (T6), and after 12 months (T12). We included 114 patients in the study (76% males, median age 62.5 years), finding isolated elevation of at least one serum antibody in up to 80% of them. We described fluctuating positive autoantibodies in the one year of observation, with only 45.6% of patients positive for ANA and less than 2% positive for ASMA, at all three times. Isolated elevation of tissue antibodies was not related to gender, age, HCC at transplant, early rejection, cause of transplantation, immunotherapy taken, and age at the time of the study. We did not detect a higher prevalence of positive autoimmunity in patients with signs of liver injury. ANA and ASMA evaluation in patients with liver transplantation and no history of autoimmune disease has no clinical relevance, since it varies in time and is not related to any risk factors or liver injury. Routine autoimmunity evaluation should be avoided.

Abstract
De novo autoimmune hepatitis (DAIH) is a rare clinical condition with features that resemble those of autoimmune hepatitis (AIH) in patients undergoing liver transplantation (LT) for nonautoimmune liver disease. The diagnosis of this entity has been based on the presence of biochemical and histological patterns similar to those observed in the primary AIH, although several considerations must be taken into account. The impact of DAIH on graft survival is relevant, and early diagnosis and treatment is associated with a good longterm outcome. Although glutathione S-transferase theta 1 (GSTT1) alloimmune recognition has been shown to be involved in the pathogenesis of DAIH, further studies are necessary to fully determine its pathogenic mechanisms and risk factors. We review the pathophysiology, the most common histological patterns, the treatment strategies, and the longterm outcomes of DAIH after LT with a special focus on GSTT1.

Abstract
The Banff Working Group on Liver Allograft Pathology reviewed and discussed literature evidence regarding antibody-mediated liver allograft rejection at the 11th (Paris, France, June 5-10, 2011), 12th (Comandatuba, Brazil, August 19-23, 2013), and 13th (Vancouver, British Columbia, Canada, October 5-10, 2015) meetings of the Banff Conference on Allograft Pathology. Discussion continued online. The primary goal was to introduce guidelines and consensus criteria for the diagnosis of liver allograft antibody-mediated rejection and provide a comprehensive update of all Banff Schema recommendations. Included are new recommendations for complement component 4d tissue staining and interpretation, staging liver allograft fibrosis, and findings related to immunosuppression minimization. In an effort to create a single reference document, previous unchanged criteria are also included.

Abstract
Approximately 10% of children with autoimmune hepatitis (AIH) and 30% of those with sclerosing cholangitis (SC) require liver transplantation (LT). LT is indicated in patients who present with fulminant hepatic failure (ie, with encephalopathy) and in those who develop end-stage liver disease despite treatment. After LT, recurrent AIH is reported in approximately 30% of patients and recurrent SC in up to 50%. Diagnosis of recurrence is based on biochemical abnormalities, seropositivity for autoantibodies, interface hepatitis on histology, steroid dependence, and, for SC, presence of cholangiopathy. Recurrence of SC after LT is often associated with poorly controlled inflammatory bowel disease (IBD). Recurrence may even appear years after LT; therefore, steroid-based immunosuppression should be maintained at a higher dose than that used for patients transplanted for nonautoimmune liver diseases. Although the impact of recurrent disease on graft function is controversial, it seems that in pediatric LT recipients recurrence of AIH or SC is associated with compromised graft survival. Exacerbation of preexistent IBD may be observed after LT for SC or AIH, and IBD appears to have a more aggressive course than before LT. In addition, IBD can develop de novo following LT.

Abstract
Autoimmune hepatitis (AIH) is a severe liver disease affecting all age groups worldwide. Novel basic and clinical aspects of AIH, addressed at a Monothematic Conference in London in September 2015, are highlighted in this review. The diagnosis of AIH relies upon detection of characteristic autoantibodies, hypergammaglobulinemia, and interface hepatitis on liver histology. The International Autoimmune Hepatitis Group (IAIHG) has devised diagnostic scoring systems to help in comparative studies and clinical practice. AIH arises in a genetically predisposed host, when yet unknown triggers - such an encounter with a pathogen - lead to a T cell-mediated immune response targeting liver autoantigens. This immune response is inadequately controlled because regulatory mechanisms are impaired. The mainstay of treatment for AIH is immunosuppression, which should be instituted as soon as the diagnosis is made. Standard treatment regimens include relatively high doses of predniso(lo)ne, which are tapered gradually as azathioprine is introduced. Recent guidelines have described newer treatment regimens and have tightened the goal of therapy to complete normalization of biochemical, serological and histological parameters. Mycophenolate mofetil, calcineurin inhibitors, mTOR inhibitors and biological agents are potential salvage therapies, but should be reserved for selected non-responsive patients and administered only in experienced centers. Liver transplantation is a life-saving option for those patients who progress to end-stage liver disease. Further dissection of cellular and molecular pathways involved in AIH pathogenesis is likely to lead to the discovery of novel, tailored and better tolerated therapies.

Abstract
Autoimmune liver diseases (AILD) are rare diseases with a reported prevalence of less than 50 per 100 000 population. As the research landscape and our understanding of AILDs and liver transplantation evolves, there remain areas of unmet needs. One of these areas of unmet needs is prevention of disease recurrence after liver transplantation. Disease recurrence is not an insignificant event because allograft loss with the need for retransplantation can occur. Patients transplanted for AILD are more likely to experience acute rejection compared to those transplanted for non-AILD, and the reason(s) behind this observation is unclear. Tasks for the future include a better understanding of the pathogenesis of AILD, definition of the precise pathogenetic mechanisms of recurrent AILD, and development of strategies that can identify recipients at risk for disease recurrence. Importantly, the role of crosstalk between alloimmune responses and autoimmune responses in AILD is an important area that needs further study. This article reviews the relevant literature of de novo autoimmune hepatitis, recurrent autoimmune hepatitis, recurrent primary sclerosing cholangitis, and recurrent primary biliary cirrhosis in terms of the clinical entity, the scientific advancements, and future scientific goals to enhance our understanding of these diseases.

Abstract
A subset of human regulatory T cells (Tregs) can secrete IFN-γ or IL-17, and thus share features of TH1 or TH17 effector cells and lose suppressive function. The main factors driving this differentiation of Tregs toward a proinflammatory phenotype include IL-12 for TH1-like and IL-6 for TH17-type Tregs. In this study we show that Tregs of patients with de novo autoimmune hepatitis (dAIH) display increased frequencies of proinflammatory IFN-γ and IL-17 cytokines. Irrespective of a fully demethylated FOXP3 locus, Tregs of subjects with dAIH are functionally impaired. In line with the observed Treg phenotype, we detected the presence of two dominant cytokines (IL-12 and IL-6) clustering with CD68(+) monocyte/macrophage cells in livers of subjects with dAIH, and isolated monocytes of subjects with dAIH secrete high levels of proinflammatory IL-12 and IL-6, suggesting that this inflammatory milieu is key for functional impairment of Tregs. Importantly, the blockade of IFN-γ partially restores suppressive function of Tregs of subjects with dAIH, indicating that monocyte/macrophage-derived triggers might play a central role in Treg dysfunction and pathogenesis of dAIH.

Abstract
In the two past decades, a number of communications, case-control studies, and retrospective reports have appeared in the literature with concerns about the development of a complex set of clinical, laboratory and histological characteristics of a liver graft dysfunction that is compatible with autoimmune hepatitis. The de novo prefix was added to distinguish this entity from a pre-transplant primary autoimmune hepatitis, but the globally accepted criteria for the diagnosis of autoimmune hepatitis have been adopted in the diagnostic algorithm. Indeed, de novo autoimmune hepatitis is characterized by the typical liver necro-inflammation that is rich in plasma cells, the presence of interface hepatitis and the consequent laboratory findings of elevations in liver enzymes, increases in serum gamma globulin and the appearance of non-organ specific auto-antibodies. Still, the overall features of de novo autoimmune hepatitis appear not to be attributable to a univocal patho-physiological pathway because they can develop in the patients who have undergone liver transplantation due to different etiologies. Specifically, in subjects with hepatitis C virus recurrence, an interferon-containing antiviral treatment has been indicated as a potential inception of immune system derangement. Herein, we attempt to review the currently available knowledge about de novo liver autoimmunity and its clinical management.

Abstract
Approximately 24,000 liver transplants are performed annually worldwide, almost 7000 of which are performed in the USA. Survival is excellent and continues to improve, with 1-year survival currently exceeding 85 %, but effective management of patients after liver transplantation is critical to achieve optimal results. A plethora of diseases can affect the transplanted allograft, ranging from recurrence of the original disease to de novo liver pathology, and diagnosis can be complicated by nonclassical presentation, de novo disease, or inconclusive histology. Patients can remain asymptomatic despite significant damage to the transplanted liver, so prompt identification and treatment of liver disease after transplantation is crucial to preserve allograft function. Liver function tests are routinely taken throughout the postoperative period to monitor the graft. Although nonspecific, they are inexpensive, noninvasive, and sensitive for allograft disease and can quickly alert physicians to the presence of asymptomatic pathology. This review will outline possible causes of liver function test abnormalities in the late posttransplant period and provide guidance for investigation, diagnosis, and management.

Abstract
Nearly one-third of patients with inflammatory bowel disease (IBD) have abnormal liver tests, which can be indicative of underlying hepatic disease. Primary sclerosing cholangitis has a clear association with ulcerative colitis, but other autoimmune disorders such as autoimmune hepatitis (AIH) have also been associated with IBD. AIH may also occur in the setting of an overlap syndrome or in the setting of medications, particularly tumor necrosis factor alpha inhibitors. Importantly, some studies have shown that IBD patients with AIH fail treatment more frequently than IBD patients without AIH. This review will focus on the clinical characteristics, diagnosis, and management of autoimmune hepatitis in inflammatory bowel disease patients.

Abstract
INTRODUCTION Pegylated interferon and ribavirin (PEGIFN/RBV) therapy for recurrent hepatitis C after liver transplantation (LT) is associated with a lower sustained virological response (SVR) rate as well as more frequent side effects compared to non-transplant patients. We aimed to determine the incidence and clinical characteristics of LT recipients with recurrent hepatitis C who developed immunological dysfunction (ID) during or after PEG-IFN/RBV therapy and to assess its impact on patient and graft survival. METHODS Seventy-four deceased donor LT recipients with histological recurrence of hepatitis C were treated with PEG-IFN/RBV from 1/00 to 12/08. ID was defined as biopsy-proven rejection or moderate plasma cell hepatitis. Patients were followed up until death, re-LT or 30 September 2011. RESULTS Twelve patients (16 %) had ID, 8 (10.7 %) had cholestasis without ID, while 54 had no ID/cholestasis during or after discontinuation of PEG-IFN/RBV therapy. Biopsy-proven acute cellular rejection prior to (hazard ratio = 4.87, p = 0.009) and type of immunosuppression at the time of initiation of PEG-IFN/RBV were the only independent predictors of ID. Patients who were on tacrolimus at the time of initiation of PEG-IFN/RBV had a significantly lower risk of ID compared to those who were on cyclosporine (HR 0.254, p = 0.023). Patients with ID had a trend toward a lower SVR rate (25 vs. 54 %, p = 0.18) and a significantly higher rate of graft failure (33 vs. 4 %, p = 0.004) compared to patients with no ID/cholestasis. CONCLUSIONS ID is common during or after PEG-IFN/RBV therapy for recurrent hepatitis C and frequently associated with decreased graft survival, trending toward low rates of SVR. Careful monitoring of liver biochemistries during or after PEG-IFN/RBV therapy with a low threshold to biopsy patients and particularly those receiving cyclosporine-based immunosuppression may improve outcomes in these patients.

Abstract
Liver Transplantation (LT) is an effective treatment for patients with end-stage liver disease including autoimmune hepatitis (AIH). Indication for LT for AIH does not differ basically from other liver diseases including both acute and chronic types of disease progression, although it is reported to be an infrequent indication for LT worldwide due to the therapeutic advances of immunosuppression. The outcome following LT is feasible, with current patient and graft survival exceeding 75% at 5 years. Recurrent and de-novo AIH posttranslant has also been reported; and this seems to have important clinical implications because its management differs from the standard treatment for allograft rejection. In this review, we discuss the characteristics of AIH, focusing on the indication for LT and issues raised following LT.

Abstract
Autoantibodies are frequently detected after liver transplantation (LT), but their role is unclear. This study was designed to address three points: autoantibody prevalence pre-LT and over time up to five yr after LT, identification of possible predictors of autoantibody formation, and correlation between autoantibodies and graft dysfunction. To these aims, we retrospectively evaluated 92 consecutive LT recipients for whom prospectively stored frozen sera were available for autoantibodies assessment by immunofluorescence. The overall autoantibody prevalence resulted significantly higher after LT than before LT (64% vs. 27%, p < 0.001 and 35.9% vs. 8.7%, p < 0.001 considering cutoff titer of ≥ 1:80 and ≥ 1:160, respectively). Recipient gender, donor age and gender, and indication for LT and main immunosuppressant (cyclosporine vs. tacrolimus) were not associated with the presence of autoantibodies. Patients with graft dysfunction had a significantly higher autoantibody prevalence irrespective of the etiology of liver injury as compared to those patients with persistently normal liver biochemistry, but only for cutoff titers ≥ 1:160 (p = 0.004). No cases of de novo autoimmune hepatitis were observed. In conclusion, autoantibodies are very frequently detected after LT also at high titers and their association with graft dysfunction likely represents an aspecific indicator of liver injury.

Abstract
Juvenile autoimmune hepatitis (JAIH) is a progressive inflammatory liver disease, affecting mainly young girls, from infancy to late adolescence, characterized by active liver damage, as shown by high serum activity of aminotransferases, by elevated immunoglobulin G levels, high titers of serum non organ-specific and organ-specific autoantibodies, and by interface hepatitis on liver biopsy. It is a multifactorial disease of unknown etiology in which environmental factors act as a trigger in genetically predisposed individuals. Two types of JAIH are identified according to the autoantibody panel detected at diagnosis: AIH-1, characterized by the presence of anti-smooth muscle antibody and/or antinuclear antibody and AIH-2, by anti-liver-kidney microsomal antibody type 1 and/or by the presence of anti-liver cytosol type 1 antibody. Epidemiological distribution, genetic markers, clinical presentation and pattern of serum cytokines differentiate the two types of AIH suggesting possible pathogenetic mechanisms. The most effective therapy for AIH is pharmacological suppression of the immune response. Treatment should be started as soon as the diagnosis is made to avoid severe liver damage and progression of fibrosis. The aim of this review is to outline the most significant and peculiar features of JAIH, based largely on our own personal database and on a review of current literature.

Abstract
To evaluate the efficacy and safety of early steroid withdrawal or steroid avoidance in the tacrolimus (Tac)-based immunosuppressive regimen for liver transplant recipients. According to the requirements of the Cochrane systematic review, a thorough literature search was performed in the PubMed/MEDLINE and Cochrane electronic databases between 1995 and 2011 using the key words "liver transplantation," "Tac," and "steroid free" or "steroid withdrawal," restricting articles to the English language. Data were processed for a meta-analysis by Stata 12 software. Altogether 17 prospective randomized controlled trials containing 1,980 transplanted patients were included in this study. The overall pooled RR estimates of 1-, 2-, 3-, and 5-year patient and graft survival rates were 0.985, 0.998, 0.995, and 1.100 (95 % CI 0.925-1.048, 0.934-1.067, 0.894-1.107, and 0.968-1.250, respectively), as well as 0.998, 0.993, 0.945, and 1.053, respectively (95 % CI 0.928-1.072, 0.902-1.092, 0.833-1.072, and 0.849-1.307, respectively). The other pooled RR estimates of acute rejection and chronic rejection rates for all enrolled studies were 1.077 and 0.311 (95 % CI 0.864-1.343 and 0.003-37.207). As for secondary predictors, the pooled RR estimates such as HCV recurrence, HCC recurrence, diabetes, hypertension, kidney dysfunction, bacterial infection, and CMV were 1.101, 1.403, 1.836, 1.607, 0.842, 1.096, and 2.280, respectively (95 % CI 0.964-1.257, 0.422-4.688, 1.294-2.606, 0.926-1.228, 0.693-1.022, 0.783-1.533, and 1.500-3.465, respectively). There were no differences between the steroid group and steroid-free group for all clinical observational indices except for the incidence of diabetes (p = 0.001) and CMV infection (p < 0.001). In summary, our study indicate that rapid discontinuation of steroid in the Tac-based immunosuppressive regimen may not lead to an increased risk of morbidity and rejection rate.

Abstract
Primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH) represent the three major autoimmune liver diseases (AILD). PBC, PSC, and AIH are all complex disorders in that they result from the effects of multiple genes in combination with as yet unidentified environmental factors. Recent genome-wide association studies have identified numerous risk loci for PBC and PSC that host genes involved in innate or acquired immune responses. These loci may provide a clue as to the immune-based pathogenesis of AILD. Moreover, many significant risk loci for PBC and PSC are also risk loci for other autoimmune disorders, such type I diabetes, multiple sclerosis and rheumatoid arthritis, suggesting a shared genetic basis and possibly similar molecular pathways for diverse autoimmune conditions. There is no curative treatment for all three disorders, and a significant number of patients eventually progress to end-stage liver disease requiring liver transplantation (LT). LT in this context has a favourable overall outcome with current patient and graft survival exceeding 80% at 5years. Indications are as for other chronic liver disease although recent data suggest that while lethargy improves after transplantation, the effect is modest and variable so lethargy alone is not an indication. In contrast, pruritus rapidly responds. Cholangiocarcinoma, except under rigorous selection criteria, excludes LT because of the high risk of recurrence. All three conditions may recur after transplantation and are associated with a greater risk of both acute cellular and chronic ductopenic rejection. It is possible that a crosstalk between alloimmune and autoimmune response perpetuate each other. An immunological response toward self- or allo-antigens is well recognised after LT in patients transplanted for non-autoimmune indications and sometimes termed "de novo autoimmune hepatitis". Whether this is part of the spectrum of rejection or an autoimmune process is not clear. In this manuscript, we review novel findings about disease processes and mechanisms that lead to autoimmunity in the liver and their possible involvement in the immune response vs. the graft after LT.

Abstract
Liver transplantation (LT) is an effective treatment for patients with end-stage autoimmune liver diseases such as primary biliary cirrhosis, primary sclerosing cholangitis, and autoimmune hepatitis. Indications for LT for these diseases do not differ substantially from those used for other acute or chronic liver diseases. Despite the good outcomes reported, the recurrence of autoimmune liver disease is relatively common in the allograft. In addition, it has become apparent that autoimmunity and autoimmune liver disease can arise de novo after transplantation for nonautoimmune liver disorders. An awareness of the existence of recurrent autoimmune liver diseases and de novo autoimmune hepatitis after LT has important clinical implications because their management differs from the standard antirejection treatment and is similar to the management of classic autoimmune liver diseases in the native liver.

Abstract
Autoimmune hepatitis (AIH) was the first chronic liver disease in which remission was achieved by immunosuppression. Prognosis is poor when left untreated. Since the original description in 1950 by Waldenström, the initially reported treatment option has remained until today and is the core of the basic therapeutic strategy of inducing remission with steroids and azathioprine. Immunosuppression as a treatment concept spans different situations including the induction and maintenance of remission, treatment of nonresponders, avoidance of side effects, perioperative treatment of liver transplantation candidates and the issue of withdrawal. Alternative immunosuppressive drugs such as transplantation immunosuppressants have been administered and reported in small series. In an attempt to optimize side effect management, a recent large multicenter prospective treatment trial suggests that budesonide may offer an alternative for noncirrhotic AIH patients with lower steroid side effects. With an early diagnosis and effective therapy, only 4% of transplant candidates are transplanted for AIH. After liver transplantation there is a considerable risk for graft loss because of recurrent AIH, and lifelong vigilance and therapeutic attention is important.

Abstract
Dn-AIH is a long-term complication after LT. The aim of this study was to analyze the occurrence of autoantibodies in pediatric recipients and the clinical significance. From 1992 to 2008, 96 pediatric LT for non-autoimmune liver diseases were performed in 94 children in our institution. Serum autoantibodies were checked in 68 subjects (73.9%). A positive autoantibody was defined as titers ≥1:40 for ANA, or ≥1:20 for ASMA, anti-LKM, and AMA. Autoantibodies were detectable in 51 of 68 patients (75.0%). There was positivity for ANA in 30 patients, ASMA in 32, and AMA in three, while anti-LKM was all negative. Immunosuppressive treatment with CsA, more than one episode of rejection, and abnormal ALT were risk factors for the development of autoantibodies. The incidence of the development of autoantibodies was 75.0% in pediatric LT cases in this study. ASMA was the most commonly found autoantibody. Autoantibodies may not play a sentinel role for dn-AIH after LT.

Abstract
Autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC) are poorly understood autoimmune liver diseases. Immunosuppression is used to treat AIH and ursodeoxycholic acid is used to slow the progression of PBC. Nevertheless, a proportion of patients with both disorders progress to liver failure. Following liver transplantation, up to a third of patients with PBC experience recurrent disease. Moreover a syndrome referred to as "de novo AIH" occurs in a proportion of patients regardless of maintenance immunosuppression, who have been transplanted for disorders unrelated to AIH. Of note, the use of cyclosporine A appears to protect against the development of recurrent PBC and de novo AIH even though it is a less potent immunosuppressive compared to tacrolimus. The reason why cyclosporine A is protective has not been determined. However, a virus resembling mouse mammary tumor virus (MMTV) has been characterized in patients with PBC and AIH. Accordingly, we hypothesized that the protective effect of cyclosporine A in liver transplant recipients may be mediated by the antiviral activity of this cyclophilin inhibitor. Treatment of the MMTV producing MM5MT cells with different antivirals and immunosuppressive agents showed that both cyclosporine A and the analogue NIM811 inhibited MMTV production from the producer cells. Herein, we discuss the evidence supporting the role of MMTV-like human betaretrovirus in the development of PBC and de novo AIH and speculate on the possibility that the agent may be associated with disease following transplantation. We also review the mechanisms of how both cyclosporine A and NIM811 may inhibit betaretrovirus production in vitro.

Abstract
Autoimmune hepatitis (AIH) is a unique form of immune-mediated disease that attacks the liver through a variety of immune mechanisms. The outcomes of AIH are either acute liver disease, which can be fatal, or, more commonly, chronic progressive liver disease, which can lead to decompensated liver cirrhosis if left untreated. AIH has characteristic immunological, and pathological, features that are important for the establishment of the diagnosis. More importantly, most patients with AIH have a favorable response to treatment with prednisolone and azathioprine, although some patients with refractory AIH or more aggressive disease require more potent immune-suppressant agents, such as cyclosporine or Mycophenolate Mofetil. In this paper, we discuss the immunological, pathological and clinical features of AIH, as well as the standard and alternative treatments for AIH.

Abstract
BACKGROUND/AIMS De novo autoimmune hepatitis (AIH) describes the development of hepatitis with autoimmune features in liver transplant (LT) patients without prior diagnosis of AIH. We aimed to evaluate the incidence and risk factors for de novo AIH. METHODS A cohort of 576 patients with LT for aetiologies other than AIH was evaluated. RESULTS De novo AIH was diagnosed in 17 patients (3%) with an overall incidence of 4.0 cases per 1000 patient-years. By univariate Cox analysis, patients who received cyclosporine A had lower risk (HR 0.24, 95% CI 0.07-0.80, P = 0.02), whereas patients who had female donors (HR 3.03, 95% CI 1.11-8.25, P = 0.03), donors ≥40-years (HR 6.95, 95% CI 1.93-25.03, P = 0.003), and those who received tacrolimus (HR 4.39, 95% CI 1.47-13.13, P = 0.008) and mycophenolate mofetil (HR 6.37, 95% CI 1.62-25.13, P = 0.008) had higher risk. Survival was similar in patients with de novo AIH compared with the LT population (mean survival time, 17 ± 1.5 vs. 16 ± 0.5 years, Log-rank test; P = 0.4). CONCLUSIONS The incidence of de novo AIH is low and does not impact on long-term survival. Recipients of female or older donor grafts, or recipients using tacrolimus, or mycophenolate mofetil as part of their immunosuppressive regimen have a higher risk of de novo AIH, whereas LT recipients maintained on cyclosporine A have a lower risk.

Abstract
Autoimmune hepatitis can recur or appear de novo after liver transplantation, and it can result in hepatic fibrosis, graft loss, and re-transplantation. The goals of this review are to describe the prevalence, manifestations, putative pathogenic mechanisms, outcomes, and management of these occurrences. Autoimmune hepatitis recurs in 8-12 % of transplanted patients at 1 year and 36-68 % at 5 years. Recurrence may be asymptomatic and detected only by surveillance liver test abnormalities or protocol liver tissue examination. Autoantibodies that characterized the original disease, hypergammaglobulinemia, increased serum immunoglobulin G level, and histological findings of interface hepatitis, lymphoplasmacytic infiltration, perivenular hepatocyte necrosis, pseudo-rosetting, and acidophil bodies typify recurrence. Premature corticosteroid withdrawal and pre-transplant severity of the original disease are possible risk factors. De novo autoimmune hepatitis occurs in 1-7 % of patients 0.1-9 years after transplantation, especially in children. The appearance of autoantibodies may herald its emergence, and antibodies to glutathione-S-transferase T1 have been predictive of the disease. Recurrent disease may reflect recruitment of residual memory T lymphocytes and host-specific genetic predispositions, whereas de novo disease may reflect an allo-antigenic immune response and molecular mimicries that override self-tolerance. Treatment should be appropriate for autoimmune hepatitis and not based on anti-rejection drugs. Corticosteroid therapy alone or combined with azathioprine is the essential treatment. The substitution of mycophenolate mofetil for azathioprine and switch of the calcineurin inhibitor or its replacement with rapamycin have also been used for refractory disease. Re-transplantation has been necessary in 8-23 %.

Abstract
De novo autoimmune hepatitis (AIH) is a rare graft dysfunction occurring in patients having undergone liver transplantation (LT) for causes other than AIH. We describe for the first time a case of de novo AIH associated with the administration of parathyroid hormone 1-34 [PTH(1-34)] and PTH(1-84) for severe osteoporosis. A 61-year-old woman was referred to our metabolic bone clinic due to severe osteoporosis, 3 years after LT for primary biliary cirrhosis. Initial treatment with PTH(1-34) led to asymptomatic hypertransaminasemia (two-fold the upper limit of normal), which normalized after drug discontinuation. A new flare of transaminases (three-fold the upper limit of normal) along with elevated alkaline phosphatase was observed after administration of PTH(1-84), which did not resolve after PTH(1-84) withdrawal. Subsequently, after exclusion of common causes of liver enzyme elevation, a liver biopsy was performed. Histological findings showed de novo AIH, which responded rapidly to treatment with methylprednisolone.

Abstract
We have investigated the inflammatory infiltrate in post-transplant dn-AIH, a form of late insidious graft rejection, focusing on transcription factors defining effector and T-regs, using an antigen retrieval immunohistochemical method on archived liver tissue, and compared it with ACR and classical AIH. Paraffin-embedded liver biopsies from pediatric patients with dn-AIH (n = 10), ACR (n = 10), and AIH (n = 13) were selected randomly and stained using antibodies directed to CD4, CD8, T-bet (marker of Th1 polarization), GATA-3 (marker of Th2 polarization), FOXP3 (marker for T regulatory cells), IL-17, CD56 (NK cells), and perforin. Portal and lobular lymphocytic infiltrate was assessed semi-quantitatively. Prominent CD4, CD8, and T-bet positivity were present in both the lobular and portal infiltrate of all three conditions. Overall T-bet score of lobular inflammation in the dn-AIH group was lower than in the ACR and AIH groups (p = 0.02). In contrast, most samples showed absent or minimal GATA-3 positivity. FOXP3, CD56, IL-17, and perforin staining of mild to moderate severity were present in all three groups in both the portal and lobular infiltrate. A Th1 polarization of the inflammatory infiltrate characterizes dn-AIH, but also ACR and AIH.

Abstract
De novo autoimmune hepatitis (DAIH) is a well-recognized complication of pediatric liver transplantation (LT). The diagnosis is largely based on elevated liver function test results and the development of autoimmune antibodies. The histology of DAIH was first described in 1998. We present detailed histological data from the largest series to date of pretreatment and posttreatment biopsy samples from pediatric LT patients with DAIH. The histological evaluation included first an assessment of the predominant pattern of injury (hepatitis, rejection, or bile duct obstruction). Then, the necroinflammatory activity (interface, lobular, and perivenular), plasma cell density, rejection activity index, and fibrosis were scored. Seventy of 685 pediatric patients (10.2%) who underwent LT developed DAIH according to clinical and biopsy findings. Fifty-one pretreatment biopsy samples and 38 posttreatment biopsy samples were available for a retrospective review. The predominant pattern of injury (hepatitis, rejection, or bile duct obstruction) was determined, and biopsy samples were scored for the necroinflammatory activity (interface, lobular, and perivenular), plasma cell density, rejection activity index, and fibrosis. The most common pattern of injury was lobular hepatitis, which was frequently unaccompanied by interface necroinflammatory activity or prominent plasma cell infiltrates. Seven of the 51 cases had features strongly suggestive of acute rejection. Posttreatment biopsy samples showed a reduction in the degree of necroinflammatory activity and plasma cell infiltrates. In most patients, the degree of fibrosis was stable or had regressed. Because the histological features of DAIH are variable and nonspecific, a high index of suspicion and correlation with autoimmune antibodies are necessary to establish the diagnosis. In the majority of patients with DAIH, treatment appears to yield good clinical outcomes and histological improvements.
