Background and Aims: The European Reference Network on Hepatological Diseases (ERN RARE-LIVER) launched the prospective, multicentre, quality-controlled R-LIVER registry on rare liver diseases. The aim of this study was to assess the presentation and outcome of autoimmune hepatitis (AIH) after 1 year of treatment., Methods: Data were prospectively collected at the time of diagnosis and after 6 and 12 months follow-up. Complete biochemical response (CBR) was defined as normalization of alanine aminotransferase (ALT) and immunoglobulin G (IgG) serum levels., Results: A total of 231 patients from six European centres were included in the analysis. After 6 months of treatment 50% (106/212), and after 12 months 63% (131/210) of patients reached CBR with only 27% (56/211) achieving a steroid-free CBR within the first year. Overall, 16 different treatment regimens were administered. Change of treatment, mostly due to intolerance, occurred in 30.4% within the first 6 months. In multivariate analysis, younger age at diagnosis (odds ratio [OR] = 1.03 [95% confidence interval (CI) 1.01-1.05]; p = .007), severe fibrosis (OR .38 [95% .16-.89], p = .026) and change of treatment within the first 6 months (OR .40 [95% CI .2-.86]; p = .018) were associated with a lesser chance of ALT normalization at 12 months follow-up., Conclusion: The landscape of AIH treatment in Europe is highly heterogeneous, even between expert centres. The results from this first European multicentre prospective registry reveal several unmet needs, highlighted by the overall low rates of CBR and the frequent failure to withdraw corticosteroids., (© 2024 The Author(s).

Background: The impact of primary biliary cholangitis (PBC) on health-related quality of life (HRQOL) is poorly understood. The aim of this study was to compare HRQOL in Danish patients with PBC to the general population and to assess associations to clinical and laboratory data., Methods: We conducted a single-centre, cross-sectional questionnaire study in patients with PBC using the SF-36 and EQ-5D-5L. Clinical and paraclinical data were obtained from patients' healthcare records. SF-36 scores were compared to an age- and gender-matched Danish general population. A general linear model was used to explore which variables were associated with main SF-36 scores., Results: Sixty-nine patients with PBC were included. Compared to the Danish general population, patients with PBC had a significantly lower HRQOL in the domains bodily pain, general health, vitality, social functioning, mental health and mental component summary score. No clinical characteristics (gender, age at inclusion, concurrent autoimmune hepatitis, pruritus or cirrhosis) or biochemical markers were significantly associated with main SF-36 scores (physical and mental component summary)., Conclusions: The study is the first to report on HRQOL in a well-characterized PBC patient population from Denmark. Danish patients with PBC had a significantly impaired HRQOL compared to the general population with the greatest impairment in mental aspects. Reductions in HRQOL were independent of clinical characteristics and biochemical markers why HRQOL should be considered as an independent outcome.

Autoimmune liver diseases are associated with an increased risk of diabetes, yet the underlying mechanisms remain unknown. In this cross-sectional study, we investigated the glucose-regulatory disturbances in patients with autoimmune hepatitis (AIH, n = 19), primary biliary cholangitis (PBC, n = 15), and primary sclerosing cholangitis (PSC, n = 6). Healthy individuals ( n = 24) and patients with metabolic dysfunction-associated steatotic liver disease (MASLD, n = 18) were included as controls. Blood samples were collected during a 120-min oral glucose tolerance test. We measured the concentrations of glucose, C-peptide, insulin, glucagon, and the two incretin hormones, glucose insulinotropic peptide (GIP) and glucagon-like peptide-1 (GLP-1). We calculated the homeostasis model assessment of insulin resistance (HOMA-IR), whole body insulin resistance (Matsuda index), insulin clearance, and insulinogenic index. All patient groups had increased fasting plasma glucose and impaired glucose responses compared with healthy controls. Beta-cell secretion was increased in AIH, PBC, and MASLD but not in PSC. Patients with AIH and MASLD had hyperglucagonemia and hepatic, as well as peripheral, insulin resistance and decreased insulin clearance, resulting in hyperinsulinemia. Patients with autoimmune liver disease had an increased GIP response, and those with AIH or PBC had an increased GLP-1 response. Our data demonstrate that the mechanism underlying glucose disturbances in patients with autoimmune liver disease differs from that underlying MASLD, including compensatory incretin responses in patients with autoimmune liver disease. Our results suggest that glucose disturbances are present at an early stage of the disease. NEW & NOTEWORTHY Patients with autoimmune liver disease but without overt diabetes display glucose disturbances early on in their disease course. We identified pathophysiological traits specific to these patients including altered incretin responses.

Background & Aims: Alcohol-related hepatitis (AH) and alcohol-related cirrhosis are grave conditions with poor prognoses. Altered hepatic lipid metabolism can impact disease development and varies between different alcohol-related liver diseases. Therefore, we aimed to investigate lipidomics and metabolomics at various stages of alcohol-related liver diseases and their correlation with survival., Methods: Patients with newly diagnosed alcohol-related cirrhosis, who currently used alcohol (ALC-A), stable outpatients with decompensated alcohol-related cirrhosis with at least 8 weeks of alcohol abstinence (ALC), and patients with AH, were compared with each other and with healthy controls (HC). Circulating lipids and metabolites were analysed using HPLC and mass spectrometry., Results: Forty patients with ALC, 95 with ALC-A, 30 with AH, and 42 HC provided plasma. Lipid levels changed according to disease severity, with generally lower levels in AH and cirrhosis than in the HC group; this was most pronounced for AH, followed by ALC-A. Nine out of 10 free fatty acids differed between cirrhosis groups by relative increases of 0.12-0.66 in ALC compared with the ALC-A group ( p <0.0005). For metabolomics, total bile acids increased by 19.7, 31.3, and 80.4 in the ALC, ALC-A, and AH groups, respectively, compared with HC (all p <0.0001). Low sphingolipid ([d42:1] and [d41:1]) levels could not predict 180-day mortality (AUC = 0.73, p  = 0.95 and AUC = 0.73, p  = 0.95) more accurately than the model for end-stage liver disease score (AUC = 0.71), but did predict 90-day mortality (AUC d42:1  = 0.922, AUC d41:1  = 0.893; p d42:1  = 0.005, p d41:1  = 0.007) more accurately than the MELD score AUC MELD  = 0.70, p MELD  = 0.19)., Conclusions: Alcohol-related severe liver disease is characterised by low lipid levels progressing with severity of liver disease, especially low sphingomyelins, which also associate to poor prognoses., Impact and Implications: Lipidomics has the potential to diagnose and risk stratify patients with liver diseases. Lipidomics differed between patients with alcohol-related hepatitis and alcohol-related cirrhosis with and without recent alcohol use. Furthermore, lipidomics could predict short-term mortality and might be suitable as a prognostic tool in the future., Clinical Trials Registration: Scientific Ethics Committee of the Capital Region of Denmark, journal no.

Background and Aims: Patients with some chronic liver diseases have increased risk of diabetes. Whether this is also the case for patients with autoimmune liver diseases is unknown. The study aimed to calculate risk and worldwide prevalence of diabetes in patients with autoimmune hepatitis (AIH), primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC)., Methods: We performed a case-control study using data from the United Kingdom Biobank (UKB) and compared frequency of type 1 diabetes (T1D) and type 2 diabetes (T2D) in AIH and PBC with age-, sex-, BMI- and ethnicity-matched controls. Next, we performed a systematic review and proportional meta-analysis searching PubMed, Embase, Cochrane Library and Web of Science (inception to 1 May 2022 [AIH]; 20 August 2022 [PBC]; 11 November 2022 [PSC]). The pooled prevalence of diabetes was calculated using an inverse method random effects model., Results: Three hundred twenty-eight AIH patients and 345 PBC patients were identified in UKB and risk of T1D and T2D significantly increased compared with matched controls. Our systematic search identified 6914 records including the UKB study. Of these, 77 studies were eligible for inclusion comprising 36 467, 39 924 and 4877 individuals with AIH, PBC and PSC, respectively. The pooled prevalence of T1D was 3.8% (2.6%-5.7%), 1.7% (0.9%-3.1%), 3.1% (1.9%-4.8%) and of T2D 14.8% (11.1%-19.5%), 18.1% (14.6%-22.2%), 6.3% (2.8%-13.3%) in patients with AIH, PBC and PSC, respectively., Conclusions: Patients with autoimmune liver diseases have increased risk of diabetes. Increased awareness of diabetes risk in patients with autoimmune liver diseases is warranted., (© 2023 The Authors. Liver International published by John Wiley & Sons Ltd.)

Autoimmune liver diseases include autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis. They are chronic, heterogenous diseases affecting the liver which is a key metabolic organ that ensures glucose homeostasis. It is well known that patients with other chronic liver diseases such as cirrhosis and nonalcoholic fatty liver disease (NAFLD) display glucose disturbances like insulin resistance and have an increased risk of diabetes. Previous evidence on glucose disturbances in patients with autoimmune liver disease is scarce but does point towards a potentially increased risk of type 1 diabetes and type 2 diabetes. The underlying mechanisms are unknown but may reflect genetic predisposition, concurrent NAFLD and or cirrhosis development, and treatment (steroid) related impairment of glucose homeostasis. Therefore, increased awareness and surveillance of diabetes development in patients with autoimmune liver disease may be important. Overall, detection and treatment of diabetes generally follow the usual diabetes guidelines; however, in patients with advanced liver cirrhosis, HbA1c may not be a reliable marker of average glucose levels, and treatment with insulin is generally recommended. In addition, it has recently been suggested that sodium-glucose cotransporter 2 inhibitors may be beneficial in treating refractory ascites. Further research on diabetes risk in autoimmune liver disease is warranted., (Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.)

Background: Elevated serum bile acids (BA) are harmful to the heart and alterations in the BA composition have been suggested to cause cardiovascular disturbances in cirrhosis., Aim: To investigate any associations between specific groups or individual serum BA and structural and functional cardiac abnormalities in patients with cirrhosis., Methods: An explorative study in 86 patients with cirrhosis. All participants underwent extensive cardiac assessment, including cardiac MRI with quantification of myocardial extracellular volume (ECV), which is indicative of diffuse myocardial fibrosis. A panel of 15 individual serum BA and C4, a marker of de novo bile acid synthesis, were assessed., Results: Patients with advanced cirrhosis had higher levels of total BA and conjugated BA, as well as lower C4 levels (p < 0.001). Conjugated BA levels were higher in patients with a high cardiac index (p < 0.001), increased left atrial volume index (LAVI) (p < 0.001), and in those with an abnormal myocardial ECV (p < 0.05). We also found several strong correlations between conjugated BA, both as a group and individually, and parameters of cardiac dysfunction. In a model adjusted for sex, age, BMI and MELD, conjugated BA remained significantly associated with LAVI, septal e', left ventricular volumes and cardiac index. In addition, taurocholic acid correlated closely with hepatic venous pressure gradient (HVPG) (p = 0.01)., Conclusions: Increased serum concentrations of conjugated BA are associated with several cardiac parameters, indicating a potential role in the development of hyperdynamic circulation and cardiac dysfunction in cirrhosis. Moreover, taurine-conjugated BA are associated with portal hypertension., (© 2023 John Wiley & Sons Ltd.)

Acute liver failure (ALF) is rare but life-threatening. Common causes include intoxications, infections, and metabolic disorders. Indeterminate etiology is still frequent. No systematic data on incidence, causes, and outcome of ALF across Europe are available. Via an online survey we reached out to European Reference Network Centers on rare liver diseases. Numbers and etiology of ALF cases during 2020 were retrieved and diagnostic and treatment availabilities assessed. In total, 455 cases (306 adult, 149 pediatric) were reported from 36 centers from 20 countries. Intoxication was the most common cause in adult and pediatric care. The number of cases with indeterminate etiology is low. Diagnostic tools and specific treatment options are broadly available within this network. This is the first approach to report on etiology and outcome of ALF in the pediatric and adult population in Europe. High diagnostic yield and standard of care reflects the expert status of involved centers., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 by European Society for European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Background: Autoimmune hepatitis (AIH) can be clinically controlled by first-line immunosuppressive therapy in the majority of patients. However, a selective decrease in intrahepatic regulatory T cells (Treg) was observed with immunosuppressive therapy, which was even more pronounced in patients with incomplete responses than in patients who achieved biochemical remission. The effects of salvage therapies on the number of intrahepatic T and B cells, including Treg, are unclear. The hypothesis was that calcineurin inhibitors would further decrease intrahepatic Treg numbers, and the mammalian target of rapamycin inhibitors would increase intrahepatic Treg numbers., Methods: In this retrospective study at 2 centers, CD4+, CD8+ and CD4+FOXP3+ T cells, and CD79a+ B cells were quantified in surveillance biopsies under non-standard-of-care treatment [non-SOC: calcineurin inhibitor (n=10), second-line antimetabolites (n=9), mammalian target of rapamycin inhibitors (n=4)] compared with patients under the standard-of-care treatment (SOC)., Results: Intrahepatic T-cell and B-cell counts were not significantly different between patients with biochemical remission under SOC and non-SOC. However, patients with incomplete response under non-SOC had significantly lower liver infiltration with T and B cells, whereas Treg were not reduced compared with SOC. This resulted in an even higher ratio of Treg to T and B cells in non-SOC compared with SOC when biochemical remission was not achieved. The different non-SOC regimens showed no significant difference in liver infiltration with T cells, including Treg and B cells., Conclusions: Non-SOC in AIH partially controls intrahepatic inflammation by limiting the hepatic infiltration of total T and B cells as the main drivers of inflammation without further decreasing intrahepatic Treg. A negative effect of calcineurin inhibitor and a positive effect of mammalian target of rapamycin inhibitors on the number of intrahepatic Treg was not observed., (Copyright © 2023 The Author(s).

Background & Aims: Data on the management of primary sclerosing cholangitis (PSC) in European expert centres are sparse. In this study, a PSC group from the ERN RARE-LIVER surveyed European hepatologists to uncover differences in real-life clinical practices., Methods: In April 2020 a survey questionnaire was sent to members of the International PSC Study Group and ERN RARE-LIVER. Participants were asked about the size of their PSC cohort, use of medical treatments including ursodeoxycholic acid (UDCA) and surveillance for cholangiocarcinoma, gallbladder polyps and inflammatory bowel disease (IBD). Data were presented descriptively., Results: Eighty-two of 278 members responded. Fifty percent of physicians prescribed UDCA routinely to all their patients with PSC, whereas 12% never prescribed UDCA. UDCA was used for one or more indications including: alkaline phosphatase >1.5x the upper limit of normal, severe PSC changes, pruritus, PSC-IBD or patient demand. Few physicians offered other medical treatments than UDCA. The use of medical treatments was generally comparable in small (<99 patients) and large (≥99 patients) cohorts, as well as for adult and paediatric physicians. Most physicians routinely screened for cholangiocarcinoma and the most frequent modalities used were MRI and ultrasound. At detection of a gallbladder polyp of 6 mm, 46% of physicians recommended repeated ultrasound after 3-6 months, whereas 44% of physicians recommended immediate cholecystectomy. In patients with PSC without IBD at PSC diagnosis, 68% of physicians repeated colonoscopy within 3-5 years whereas 27% referred only patients who developed symptoms of IBD., Conclusion: Substantial variations in treatment and monitoring of European patients with PSC were discovered. Harmonisation of strategies is desirable to enable improved interpretation of outcome data and to optimise clinical patient care., Lay Summary: In this study, we explored how different centres in Europe manage primary sclerosing cholangitis (PSC), a rare inflammatory disease of the bile ducts. We collected information through a questionnaire sent to specialist physicians who were part of a European network for rare liver diseases. We found several differences in how patients with PSC were monitored and treated. This includes differences in surveillance for bile duct cancer, gallbladder polyps and inflammatory bowel disease. By pointing out these differences, we hope that management of PSC will be standardized, which could aid clinical research and benefit patients., Competing Interests: The authors declare that they have no conflict of interest.

Background and Aims: Alcoholic hepatitis (AH) is characterized by acute liver failure, neurocognitive impairment and renal failure. Severe inflammatory reactions are also known to occur in AH. Inflammation and bacterial translocation in the gut are thought to have major impact on disease development and progression. The mortality rate for AH is close to 50%. We aimed to assess the efficacy of rifaximin in treating AH and its impact on inflammation and metabolism., Methods: The trial was approved by relevant authorities (EudraCT no: 2014-02264-33, Scientific Ethics Committee, jr. no: H-1-2014-056). Primary outcomes were changes in metabolic and inflammatory markers. Secondary outcomes were portal hypertension, kidney and neurocognitive function., Results: Thirty-two patients were randomized to standard medical therapy (SMT) or SMT plus rifaximin, allocation was concealed. Four patients in the SMT group and five patients in the SMT + rifaximin group died due to AH and liver failure. No adverse events related to the study medication were observed. We found no significant differences in amino acids or inflammation markers (IL-2, IL-6, IL-8, IL-10, TNF-α, interferon-γ) between the groups after 28 and 90 days., Conclusion: Rifaximin does not alter inflammation or metabolism in patients with AH., Competing Interests: FB and NK have received an unrestricted grant from Norgine Denmark A/S for a clinical trial (NCT01739040) conducted in the same period as the present trial (2013-2017). Activities regarding that study was without relation to the present study. This does not alter our adherence to PLOS ONE policies on sharing data and materials.

Serum microfibrillar-associated protein 4 (sMFAP4) has been investigated as a biomarker for various diseases and is demonstrated to show significant gradual increase with severity of liver fibrosis. Ideal biomarkers used for disease diagnosis or prognosis should display deviating levels in affected individuals only and be robust to factors unrelated to the disease. Here we show the impact of normal physiological variation of sMFAP4 by characterizing the circadian variation, week-to-week variation, and physical exercise-induced levels. Serum samples from 3 groups of healthy volunteers were drawn: 7 times during a 24-hour period, 5 times during a 3-week period, and before and after a standardized physical exercise challenge. sMFAP4 was determined by AlphaLISA. Statistical analysis was performed using mixed effects modeling of repeated measurements. Circadian variation of sMFAP4 was demonstrated, with time of peak and nadir values depending on age and gender. For males, the peak values were observed during nighttime whereas for females, peak values were observed in the morning. Individual sMFAP4 levels remained stable over a period of 3 weeks and physical exercise inferred a mild negative influence. In conclusion, the circadian sMFAP4 variation was significant, and the levels could be influenced by physical activity. However, these variations were of limited magnitude relative to previously observed disease-induced levels in support of the biomarker potential of sMFAP4., Competing Interests: Declaration of conflicting interests:The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2021.)

Most patients with autoimmune hepatitis respond well to standard immunosuppressive therapy with steroids and azathioprine, and while untreated disease is usually fatal, patients who respond well to therapy have an excellent prognosis. However, insufficient response to standard therapy or intolerable side effects requiring dose adaptions or treatment changes occur in 10-20% of patients. While there is fairly good agreement on second-line treatment options, there is very wide variation in the indication and use of possible third-line therapies. Herein, the European Reference Network on Hepatological Diseases (ERN RARE-LIVER) and the International Autoimmune Hepatitis Group (IAIHG) outline a treatment algorithm for both children and adults that should help to standardise treatment approaches, in order to improve patient care and to enable the comparison of treatment results between scientific publications., Competing Interests: Conflict of interest The authors declare no conflicts of interest that pertain to this work.

Background & Aims: Few patients with primary sclerosing cholangitis (PSC) and inflammatory bowel diseases (IBDs) are exposed to tumor necrosis factor (TNF) antagonists because of the often mild symptoms of IBD. We assessed the effects of anti-TNF agents on liver function in patients with PSC and IBD, and their efficacy in treatment of IBD., Methods: We performed a retrospective analysis of 141 patients with PSC and IBD receiving treatment with anti-TNF agents (infliximab or adalimumab) at 20 sites (mostly tertiary-care centers) in Europe and North America. We collected data on the serum level of alkaline phosphatase (ALP). IBD response was defined as either endoscopic response or, if no endoscopic data were available, clinical response, as determined by the treating clinician or measurements of fecal calprotectin. Remission was defined more stringently as endoscopic mucosal healing. We used linear regression analysis to identify factors associated significantly with level of ALP during anti-TNF therapy., Results: Anti-TNF treatment produced a response of IBD in 48% of patients and remission of IBD in 23%. There was no difference in PSC symptom frequency before or after drug exposure. The most common reasons for anti-TNF discontinuation were primary nonresponse of IBD (17%) and side effects (18%). At 3 months, infliximab-treated patients had a median reduction in serum level of ALP of 4% (interquartile range, reduction of 25% to increase of 19%) compared with a median 15% reduction in ALP in adalimumab-treated patients (interquartile range, reduction of 29% to reduction of 4%; P = .035). Factors associated with lower ALP were normal ALP at baseline (P < .01), treatment with adalimumab (P = .090), and treatment in Europe (P = .083)., Conclusions: In a retrospective analysis of 141 patients with PSC and IBD, anti-TNF agents were moderately effective and were not associated with exacerbation of PSC symptoms or specific side effects. Prospective studies are needed to investigate the association between use of adalimumab and reduced serum levels of ALP further., (Copyright © 2020 AGA Institute. Published by Elsevier Inc.

Introduction: Due to the coronavirus disease 2019 (COVID-19) exposure in Denmark, first-line referral centres were established to handle all patients suspected of COVID-19 or other upper respiratory tract infection. Here we report the first experiences from a first-line referral centre from Amager-Hvidovre Hospital, situated on the outskirts of Copenhagen., Methods: A retrospective quality assessment was performed with collection of symptom patterns and COVID-19 status., Results: During the first 24 days, a total of 3,551 patients were referred for assessment of symptoms of upper respiratory tract infection and COVID-19. A total of 2,048 patients were assessed as having mild symptoms and referred for COVID-19 testing alone, whereas 337 patients were assessed clinically by a physician. Thirty-seven were positive for COVID-19 infection, 286 were negative. The most common symptoms reported were fever, coughing and dyspnoea. Fever was an independent predictor of COVID-19 infection (odds ratio (OR) = 2.25 (95% confidence interval (CI): 1.08-5.04); p = 0.037); whereas sore throat was not (OR = 0.40 (95% CI: 0.15-0.92); p = 0.045). Only a small number of patients reported loss of taste or anosmia. In total, 113 patients were admitted to hospital, the majority of patients were discharged within 24 hours with mild symptoms of upper respiratory tract infections. Three of the COVID-19-positive patients developed a severe infection and two had a fatal outcome., Conclusions: The present study is the first to report the experiences and symptom patterns of a COVID-19 first-line referral centre with efficient triage of patients in need of hospitalisation., Funding: none., Trial Registration: not relevant., (Articles published in the DMJ are “open access”.

Background & Aims: Gut-homing lymphocytes that express the integrin α4β7 and CCR9 might contribute to development of primary sclerosing cholangitis (PSC). Vedolizumab, which blocks the integrin α4β7, is used to treat patients with inflammatory bowel diseases (IBD), but there are few data on its efficacy in patients with PSC. We investigated the effects of vedolizumab in a large international cohort of patients with PSC and IBD., Methods: We collected data from European and North American centers participating in the International PSC Study Group from patients with PSC and IBD who received at least 3 doses of vedolizumab (n = 102; median vedolizumab treatment duration, 412 days). Demographic and clinical data were collected from baseline and during the follow-up period (until liver transplantation, death, or 56 days after the final vedolizumab infusion). We analyzed overall changes in biochemical features of liver and proportions of patients with reductions in serum levels of alkaline phosphatase (ALP) of 20% or more, from baseline through last follow-up evaluation. Other endpoints included response of IBD to treatment (improved, unchanged, or worsened, judged by the treating clinician, as well as endoscopic score) and liver-related outcomes., Results: In the entire cohort, the median serum level of ALP increased from 1.54-fold the upper limit of normal at baseline to 1.64-fold the upper limit of normal at the last follow-up examination (P = .018); serum levels of transaminases and bilirubin also increased by a small amount between baseline and the last follow-up examination. Serum levels of ALP decreased by 20% or more in 21 patients (20.6%); only the presence of cirrhosis (odds ratio, 4.48; P = .019) was independently associated with this outcome. Of patients with available endoscopic data, 56.8% had a response of IBD to treatment. Liver-related events occurred in 21 patients (20.6%), including bacterial cholangitis, cirrhosis decompensation, or transplantation., Conclusions: In an analysis of patients with PSC and IBD in an international study group, we found no evidence for a biochemical response to vedolizumab, although serum level of ALP decreased by 20% or more in a subset of patients. Vedolizumab appears to be well tolerated and the overall response of IBD was the same as expected for patients without PSC., (Copyright © 2020 AGA Institute. Published by Elsevier Inc.

Introduction: Risk stratification based on biochemical variables is a useful tool for monitoring ursodeoxycholic acid (UDCA)-treated patients with primary biliary cholangitis (PBC). Several UDCA response criteria and scoring systems have been proposed for risk prediction in PBC, but these have not been validated in large external cohorts., Methods: We performed a study on data of 1746 UDCA-treated patients with PBC from 25 centers in Europe, United States, and Canada. The prognostic performance of the risk scoring systems (GLOBE and UK-PBC) and the UDCA response criteria (Barcelona, Paris I, Paris II, Rotterdam, and Toronto) were evaluated. We regarded cirrhosis-related complications (ascites, variceal bleeding, and/or hepatic encephalopathy) as clinical end points., Results: A total of 171 patients reached a clinical end point during a median 7 years (range 1-16 years) of follow-up. The 5-, 10- and 15-year adverse outcome-free survivals were 95%, 85%, and 77%. The GLOBE and UK-PBC scores predicted cirrhosis-related complications better than the UDCA response criteria. The hazard ratio (HR) for a 1 standard deviation increase was HR 5.05 (95% confidence interval (CI): 4.43-5.74, P < 0.001) for the GLOBE score and HR 3.39 (95% CI: 3.10-3.72, P < 0.001) for the UK-PBC score. Overall, the GLOBE and UK-PBC risk scores showed similar and excellent prognostic performance (C-statistic, 0.93; 95% CI: 0.91%-95% vs 0.94; 95% CI: 0.91%-0.96%)., Discussion: In our international, multicenter PBC cohort, the GLOBE and UK-PBC risk scoring systems were good predictors of future cirrhosis-related complications.

Background: We studied the efficacy and safety of mycophenolate mofetil (MMF) and tacrolimus as second-line therapy in pediatric patients with autoimmune hepatitis (AIH) who were intolerant or non-responders to standard therapy (corticosteroid and azathioprine)., Patients and Methods: We performed a retrospective study of data from 13 centers in Europe, USA, and Canada. Thirty-eight patients (< 18 years old) who received second-line therapy (18 MMF and 20 tacrolimus), for a median of 72 months (range 8-182) were evaluated. Patients were categorized into two groups: Group 1 (n = 17) were intolerant to corticosteroid or azathioprine, and group 2 (n = 21) were non-responders to standard therapy., Results: Overall complete response rates were similar in patients treated with MMF and tacrolimus (55.6 vs. 65%, p = 0.552). In group 1, MMF and tacrolimus maintained a biochemical remission in 88.9 and 87.5% of patients, respectively (p = 0.929). More patients in group 2 given tacrolimus compared to MMF had a complete response, but the difference was not statistically significant (50.0 vs. 22.2%, p = 0.195). Biochemical remission was achieved in 71.1% (27/38) of patients by tacrolimus and/or MMF. Decompensated cirrhosis was more commonly seen in MMF and/or tacrolimus non-responders than in responders (45.5 vs. 7.4%, p = 0.006). Five patients who received second-line therapy (2 MMF and 3 tacrolimus) developed side effects that led to therapy withdrawal., Conclusions: Long-term therapy with MMF or tacrolimus was generally well tolerated by pediatric patients with AIH. Both MMF and tacrolimus had excellent efficacy in patients intolerant to corticosteroid or azathioprine. Tacrolimus might be more effective than MMF in patients failing previous therapy.

The name of chronic liver disease: primary biliary cirrhosis, has been changed to: primary biliary cholangitis, primarily because of the stigma associated with the word "cirrhosis", as only a minority of the patients develop cirrhosis. In this review we present data on epidemiology and discuss the current treatments with focus on ursodeoxycholic acid and the newly described effects of the farnesoid receptor agonist obeticholic acid.
