Abstract
BACKGROUND AND AIMS Primary sclerosing cholangitis (PSC) exhibits varying incidence and prevalence rates across different regions; however, comprehensive global studies examining its geographic distribution and future trends are scarce. This study presents an updated meta-analysis through 2024 and projects the global and regional prevalence of PSC from 2024 to 2040 using an illness-death multi-state model. METHODS We conducted a thorough systematic search across multiple databases to identify all primary studies published until 2024 that reported on the incidence, prevalence, and mortality rates of PSC in various regions. Using the gathered data, we developed an illness-death model to forecast the future prevalence of PSC, covering the years 2024-2040. RESULTS Our meta-analysis revealed that the global pooled incidence and prevalence rates of PSC are 0.65 and 7.52 per 100,000 persons, respectively. Projections indicate that the global prevalence of PSC will rise to 22.98 cases per 100,000 (95% CI: 21.0-24.95), corresponding to an overall increase of 28.3%. Specifically, North America is forecasted to experience a 5.45% increase in PSC cases, reaching 24.76 cases per 100,000 (95% CI: 19.63-29.88), while Western Europe is anticipated to see a more pronounced rise of 28.79%, resulting in a prevalence of 21.48 cases per 100,000 (95% CI: 18.3-24.65) by 2040. CONCLUSIONS Our findings indicate a substantial rise in the number of individuals affected by PSC in recent years and estimate a significant future burden of the disease.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic biliary inflammation associated with periductular fibrosis of the intrahepatic and extrahepatic bile ducts leading to strictures, bacterial cholangitis, decompensated liver disease and need for liver transplantation. This rare focal liver disease affects all races and ages, with a predominance of young males. There is an up to 88% association with inflammatory bowel disease. Although the aetiology is unknown and the pathophysiology is poorly understood, PSC is regarded as an autoimmune liver disease based on a strong immunogenetic background. Further, the associated risk for various malignancies, particularly cholangiocellular carcinoma, is also poorly understood. No medical therapy has been approved so far nor has been shown to improve transplant-free survival. However, ursodeoxycholic acid is widely used since it improves the biochemical parameters of cholestasis and is safe at low doses. MRI of the biliary tract is the primary imaging technology for diagnosis. Endoscopic interventions of the bile ducts should be limited to clinically relevant strictures for balloon dilatation, biopsy and brush cytology. End-stage liver disease with decompensation is an indication for liver transplantation with recurrent PSC in up to 38% of patients. Several novel therapeutic strategies are in various stages of development, including apical sodium-dependent bile acid transporter and ileal bile acid transporter inhibitors, integrin inhibitors, peroxisome proliferator-activated receptor agonists, CCL24 blockers, recombinant FGF19, CCR2/CCR5 inhibitors, farnesoid X receptor bile acid receptor agonists, and nor-ursodeoxycholic acid. Manipulation of the gut microbiome includes faecal microbiota transplantation. This article summarizes present knowledge and defines unmet medical needs to improve quality of life and survival.

Abstract
Primary sclerosing cholangitis is a chronic liver disease characterized by progressive inflammation and fibrosis of medium-large bile ducts, most commonly in association with inflammatory bowel disease. Most patients have a progressive disease course, alongside a heightened risk of hepatobiliary and colorectal cancer. Medical therapies are lacking, and this, in part, reflects a poor grasp of disease biology. As a result, current management is largely supportive, with liver transplantation an effective life-prolonging intervention when needed, but not one that cures disease. Emerging therapies targeting disease progression, as well as symptoms such as pruritus, continue to be explored. The trial design is increasingly cognizant of the application of thoughtful inclusion criteria, as well as better endpoints aimed at using surrogates of disease that can identify treatment benefits early. This is hoped to facilitate much-needed advances toward developing safe and effective interventions for patients.

Abstract
BACKGROUND AND AIMS Recent studies point out to epidemiological changes in primary sclerosing cholangitis (PSC). Our aims were to determine in PSC patients followed in several centers in a Mediterranean geographic area: (i) changes in baseline features and (ii) effect of gender on clinical course. METHODS Retrospective multicenter study of PSC patients treated in 8 hospitals in a Mediterranean area between 2000 and 2021. Charts were reviewed compiling demographic, clinical, radiological, and histological variables. RESULTS Cohort of 112 PSC patients included, 42% women, 70% diagnosed after 2010. Women were increasingly diagnosed in recent cohorts. The median time from diagnosis to the combined endpoint liver transplantation (Lt) and/or death was 6.9 years. Asthenia at diagnosis (p = 0.009) was associated with lower transplant-free survival, while diagnosis before 2005 was associated with greater LT-free survival (p < 0.001). By Cox regression, LT-free survival was not influenced by age, sex, or cirrhosis at the time of diagnosis. Women were found to have less jaundice at diagnosis (2 vs 14%; p = 0.013), higher prevalence of ANA antibodies (43.9 vs 15.7%; p = 0.003), and lower GGT levels at diagnosis (GGT 123 vs 209U/L; p = 0.014) than men. CONCLUSION In an area traditionally considered to have low prevalence, the prevalence of affected women surpasses expectations based on existing literature. There appear to be gender-related variations in the presentation of the condition, highlighting the need for confirmation through larger-scale studies.

Abstract
Primary sclerosing cholangitis (PSC) is considered an immunologically mediated disease. However, some of its features are not consistent with the typical profile of autoimmune conditions. PSC is characterized by progressive biliary fibrosis that may ultimately result in the eventual development of cirrhosis. In recent years, multiple studies have reported that the incidence and prevalence of this disease are on the rise. Consequently, patients are often diagnosed without symptoms or signs of advanced liver disease, although many still present with signs of decompensated liver disease. This article discusses the epidemiology, clinical presentation, and diagnostic workup in patients with PSC.

Abstract
BACKGROUND Primary sclerosing cholangitis (PSC) is an extraintestinal manifestation of ulcerative colitis (UC). PSC is a well-known risk factor for intrahepatic cholangiocarcinoma (ICC), and ICC is known to have a poor prognosis. CASE SUMMARY We present two cases of ICC in patients with PSC associated with UC. In the first case, a tumor was found by magnetic resonance imaging (MRI) in the liver of a patient with PSC and UC who presented to our hospital with right-sided rib pain. The second patient was asymptomatic, but we unexpectedly detected two liver tumors in an MRI performed to evaluate bile duct stenosis associated with PSC. ICC was strongly suspected by computed tomography and MRI in both cases, and surgery was performed, but unfortunately, the first patient died of ICC recurrence 16 mo postoperatively, and the second patient died of liver failure 14 mo postoperatively. CONCLUSION Careful follow-up of patients with UC and PSC with imaging and blood tests is necessary for early detection of ICC.

Abstract
BACKGROUND Gallbladder and biliary diseases are common gastrointestinal conditions associated with huge socioeconomic costs and are considered risk factors for cardiovascular diseases and digestive system cancers. The prevalence and incidence of gallbladder and biliary diseases have not received enough attention from 1990 to 2019. Several non-communicable diseases were associated with the incidence of gallbladder and biliary diseases. It is necessary to clarify the change in the incidence and disability burden of gallbladder and biliary diseases worldwide. METHODS Data on high body mass index (BMI)-related disease burden and incidence, years of life lost prematurely, and years lived with disability (YLDs) due to gallbladder and biliary diseases were obtained from the Global Burden of Disease 2019. The estimated annual percentage change was calculated to qualify the gallbladder and biliary disease burden change. RESULTS The global age-standardized incidence rate has increased from 585.35 per 100,000 (95% UI: 506.05-679.86) in 1990 to 634.32 per 100,000 (95% UI: 540.21-742.93) in 2019. And the increase in incidence was positively correlated with rising high BMI-related summary exposure value. The high BMI-related YLDs of gallbladder and biliary diseases have increased worldwide over time. Globally, the 25-49 age group suffered a rapid rise in incidence and high BMI attributable to the YLDs rate of gallbladder and biliary diseases. CONCLUSION The global incidence and high BMI-related YLDs of gallbladder and biliary diseases remain prominent to increase over the past 30 years. Notably, the incidence and high BMI-related YLDs among people aged 25-49 years have rapidly increased over time. Therefore, high BMI should be emphasized in strategic priorities for controlling gallbladder and biliary diseases.

Abstract
AIM Studies from Western countries suggest that early-onset biliary tract cancer, a rare malignancy originating from the bile ducts (cholangiocarcinoma) or gallbladder, is increasing. We performed a population-based cohort study to outline age trends in biliary tract cancer incidence in Sweden. METHODS All patients with biliary tract cancer, excluding non-biliary chiefly hepatocellular histopathology, recorded in the Swedish Cancer Register in year 1993-2019 and at age 20-84 were included. Analyses were stratified by anatomical subtype; intrahepatic, gallbladder, perihilar, distal, and not specified. We analyzed absolute incidence rates by calendar period (1993-2001, 2002-2010, and 2011-2019) and annual percentage change (APC) including 95% confidence intervals (CI) across 1993-2019 for all ages and stratified into younger (20-54 years) and older (55-84 years) patients. RESULTS Among 14,083 patients with biliary tract cancer, 1377 (9.8%) were younger. Gallbladder cancer incidence decreased (APC -2.82, 95% CI: -3.18--2.46), while intrahepatic cholangiocarcinoma increased (APC 1.74, 95% CI: 1.30-2.18), and the latter surpassed gallbladder as the most common subtype during the study period. While both intrahepatic and perihilar cholangiocarcinoma increased in both age groups, the rise was most prominent in younger adults, APC 3.01, 95% CI: 1.84-4.20 and 3.93, 95% CI: 2.08-5.81, respectively. CONCLUSION Intrahepatic and perihilar cholangiocarcinoma are increasing in Sweden and more so younger adults. Further studies are needed to elucidate the underlying reasons behind the observed trends.

Abstract
BACKGROUND & AIMS The aim of this study was to quantify the global epidemiology of primary sclerosing cholangitis (PSC), alongside the incidence of liver transplantation, cancer, and death, through robust systematic review of population-based data. METHODS We searched MEDLINE and EMBASE up to and including June 30, 2020 to identify population-based studies reporting the incidence and/or prevalence of PSC. Studies that did not report original data, or of exclusively pediatric-onset disease (diagnosis age <16 years) or exclusively PSC-associated with inflammatory bowel disease were excluded. RESULTS Of 4922 published studies, 17 fulfilled inclusion criteria; 16 documenting incidence and 14 prevalence. The highest reported incidence of PSC was reported in Northern Europe (Finland, 1.58 and Norway, 1.3 per-100,000 population, respectively) and North America (Minnesota, 1.47); with the lowest being observed across the Mediterranean Basin (Italy, 0.1). Prevalence ranged from 31.7 in Finland and 23.99 in Minnesota, to 1.33 in Singapore and 0.0 in Alaska. Of studies reporting temporal occurrence, an increase in disease incidence was observed across North America and Northern Europe (4 studies), alongside an increase in prevalence over time (4 studies). The incidence and risks for clinical outcomes were presented by 9 of the included studies. Median transplant-free survival ranged from 9.7 (United States) to 20.6 years (Netherlands), with standardized mortality ratios of 2.5 and 4.2 compared with the control population. The standardized incidence of cholangiocarcinoma ranged from 235 (Finland) to 398 (Netherlands). CONCLUSIONS Estimates of PSC incidence and prevalence vary, with most studies conducted in North America and Western Europe; the latter showing a steady increase in disease occurrence over time. Further research is needed to understand changes in disease epidemiology, including etiological drivers, the implications of rising case burden on health care policy, and better appreciation of PSC in the developing world.

Abstract
INTRODUCTION Primary sclerosing cholangitis (PSC) is a rare, chronic, and progressive cholestatic disease involving intra- and/or extrahepatic bile ducts. PSC in many patients results in end-stage liver diseases. Nearly 60% of the PSC patients suffer from concomitant inflammatory bowel diseases (IBDs). Classically, IBDs are divided into two principle types: Crohn's disease (CD) and ulcerative colitis (UC). However, with growing knowledge, PSC-associated IBD (PSC-IBD) seems to be a rather distinct entity with specific genetics, clinical, and microbiota characteristics. AREAS COVERED In this article, we aim to review the unique characteristics of PSC-IBD from clinical, genetic, and microbiota point of view. EXPERT OPINION PSC-IBD's unique characteristics contribute to the notion that it could be a distinct entity. Acknowledgment of PSC-IBD as a novel entity necessitates designing new clinical guidelines for diagnosis and developing novel therapies.

Abstract
Question What are the profiles of cancer risk associated with immune-mediated diseases? Findings In this cohort study of 478 753 participants, immune-mediated diseases were associated with an increased risk of total cancer. Organ-specific immune-mediated diseases had stronger associations with risk of local cancers than extralocal cancers, and many immune-mediated diseases were associated with increased risk of cancer in the involved organs and in the near and distant organs or different systems. Meaning The findings suggest that immune-mediated diseases are associated with risk of cancer at the local and systemic levels, supporting the role of local and systemic immunoregulation in carcinogenesis. Importance Immune regulation is important for carcinogenesis; however, the cancer risk profiles associated with immune-mediated diseases need further characterization. Objective To assess the prospective association of 48 immune-mediated diseases with the risk of total and individual cancers and the prospective association of organ-specific immune-mediated diseases with the risk of local and extralocal cancers. Design, Setting, and Participants This prospective cohort study used data from the UK Biobank cohort study on adults aged 37 to 73 years who were recruited at 22 assessment centers throughout the UK between January 1, 2006, and December 31, 2010, with follow-up through February 28, 2019. Exposures Immune-mediated diseases. Main Outcomes and Measures The association of immune-mediated diseases with risk of cancer was assessed with multivariable hazard ratios (HRs) and 95% CIs after adjusting for various potential confounders using time-varying Cox proportional hazards regression. Heterogeneity in the associations of organ-specific immune-mediated diseases with local and extralocal cancers was assessed using the contrast test method. Results A total of 478 753 participants (mean [SD] age, 56.4 [8.1] years; 54% female) were included in the study. During 4 600 460 person-years of follow-up, a total of 2834 cases of cancer were documented in 61 496 patients with immune-mediated diseases and 26 817 cases of cancer in 417 257 patients without any immune-mediated diseases (multivariable HR, 1.08; 95% CI, 1.04-1.12). Five of the organ-specific immune-mediated diseases were significantly associated with higher risk of local but not extralocal cancers: asthma (HR, 1.34; 95% CI, 1.14-1.56), celiac disease (HR, 6.89; 95% CI, 2.18-21.75), idiopathic thrombocytopenic purpura (HR, 6.94; 95% CI, 3.94-12.25), primary biliary cholangitis (HR, 42.12; 95% CI, 20.76-85.44), and autoimmune hepatitis (HR, 21.26; 95% CI, 6.79-66.61) (P < .002 for heterogeneity). Nine immune-mediated diseases were associated with an increased risk of cancers in the involved organs (eg, asthma with lung cancer [HR, 1.34; 95% CI, 1.14-1.57; P < .001] and celiac disease with small intestine cancer [HR, 6.89; 95% CI, 2.18-21.75; P = .001]); 13 immune-mediated diseases were associated with an increased risk of cancer in the near organs (eg, Crohn disease with liver cancer: [HR, 4.01; 95% CI, 1.65-9.72; P = .002]) or distant organs (eg, autoimmune hepatitis with tongue cancer [HR, 27.75; 95% CI, 3.82-199.91; P = .001]) or in different systems (eg, idiopathic thrombocytopenic purpura with liver cancer [HR, 11.96; 95% CI, 3.82-37.42; P < .001]). Conclusions and Relevance In this cohort study, immune-mediated diseases were associated with an increased risk of total cancer. Organ-specific immune-mediated diseases had stronger associations with risk of local cancers than extralocal cancers. The associations for individual immune-mediated diseases were largely organ specific but were also observed for some cancers in the near and distant organs or different systems. Our findings support the role of local and systemic immunoregulation in cancer development.

Abstract
BACKGROUND Primary sclerosing cholangitis (PSC) is associated with a broad phenotypic spectrum in different populations from diverse ethnic and racial backgrounds. This study aimed to describe the clinical characteristics and outcomes of PSC in a multicenter cohort of patients from Brazil. METHODS Data from the Brazilian Cholestasis Study Group were retrospectively reviewed to assess demographic information and clinical characteristics of PSC, as well as the outcomes, such as transplantation-free survival. RESULTS This cohort included 210 patients. After excluding 33 (15.7%) patients with PSC and overlap syndrome of autoimmune hepatitis, 177 (97 males, median age 33 (21-42) years) with clear-cut PSC were eligible for this study. Most of the patients (n = 139, 78.5%) were symptomatic, and 104 (58.7%) had advanced PSC at the time of diagnosis. Concurrent inflammatory bowel disease was observed in 78 (58.6%) of the investigated patients (n = 133), and most of them had ulcerative colitis (n = 61, 78.2%). The 1- and 5-year survival free of liver transplantation or death were 92.3 ± 2.1% and 66.9 ± 4.2%, respectively, and baseline advanced PSC, pruritus, and elevated bilirubin levels were independent risk factors for the composite adverse outcome. Females were significantly older and had lower bilirubin levels than males at baseline, but survival was not associated with sex. Approximately 12.4% (n = 22) of patients with PSC died, and 32.8% (n = 58) underwent liver transplantation at a median follow-up time of 5.3 and 3.2 years. CONCLUSION Multiethnic Brazilian PSC patients exhibited a less pronounced male predominance and a lower frequency of inflammatory bowel disease than Caucasians. Adverse outcomes were more frequent, probably due to advanced disease at baseline.

Abstract
Patients with primary sclerosing cholangitis (PSC) are at risk of hepatobiliary and gastrointestinal cancers. Increased risk of cancer is a result of the chronic, progressive fibro-inflammatory state which ultimately results in the destruction of biliary ducts. PSC is often associated with inflammatory bowel disease (IBD). Patients with PSC are at significant risk of cholangiocarcinoma (CCA), gall bladder malignancy and those with IBD are at increased risk of colorectal cancer. It is important to implement cancer surveillance protocols in these patients. The aim of these protocols is the prevention or early detection of cancerous or pre-cancerous lesions. Given that PSC is rare, large prospective studies evaluating the risk of malignancy in these patients are not available. A great deal of uncertainty exists regarding how to best implement cancer surveillance in these patients. About 50% of deaths in PSC patients are due to malignancy and many patients eventually progress to end-stage liver disease and succumb to hepatic failure. In this review, we cover cancer surveillance strategies in PSC patients based on existing literature and expert opinions.

Abstract
Primary sclerosing cholangitis (PSC) is a premalignant condition and a well-documented risk factor for cholangiocarcinoma (CCA) which is the most common malignancy in this setting and the leading cause of deaths in the recent years, with an increasing incidence. PSC-associated CCA has a geographical distribution that follows the incidence of PSC, with an observed ascending gradient from the Eastern to the Western and from the Southern to the Northern countries. It may arise at any location along the biliary tree but is most common in the perihilar area. Patients with PSC and intrahepatic or perihilar CCA are typically not suitable for liver resection, which is otherwise the treatment of choice with curative intent in patients with resectable tumours, providing a radical resection with clear margins can be achieved. This largely relates to the commonly advanced stage of liver disease at presentation, which allows consideration for liver resection only for a very limited number of suitable patients with PSC. On the other hand, remarkable progress has been reached in the last decades with the implementation of a protocol combining neoadjuvant chemoradiation and orthotopic liver transplantation (OLT) for the treatment of perihilar CCA, within specific criteria. Excellent results have been achieved particularly for PSC patients with this cancer, who seem to benefit the most from this treatment, having converted this into an accepted indication for transplantation and the standard of care in several experienced centres. Intrahepatic CCA as an indication for OLT remains controversial and has not been accepted given disappointing previous results. However, as recent studies have shown favourable outcomes in early intrahepatic CCA, it may be that under defined criteria, OLT may play a more prominent role in the future. Distal CCA in the context of PSC requires aggressive surgical treatment with curative intent, when feasible. This review provides insight about particular features of CCA in the setting of PSC, with a main focus on its incidence, considerations relating to its anatomical location and implications to treatment and outcomes, through the viewpoint of historical evolution of management, and future perspectives.

Abstract
BACKGROUND & AIMS Primary sclerosing cholangitis (PSC) is an idiopathic, cholestatic liver disease with a diverse range of clinical manifestations. Inter-regional data on PSC are variable, but its global geoepidemiology has not been well-studied. We aimed to examine the worldwide incidence, prevalence and features of PSC and PSC-inflammatory bowel disease (PSC-IBD). METHODS A systematic search of multiple databases was conducted to identify all original, full-text studies until December 2020 with data regarding the incidence rate (IR) and/or prevalence of PSC. Outcomes were PSC IR, prevalence, features and IBD concurrence. Additionally, a meta-analysis of PSC IR was performed. The study was registered in PROSPERO (CRD42021224550). RESULTS Of the 1003 studies identified, 17 studies spanning three continents were included. PSC IR was 0.60 per 100 000 person-years (PY) (95% confidence interval: 0.37-0.88 per 100 000 PY). In pooled subgroup analysis for studies conducted in Europe and North America, PSC IR was 0.62 and 0.53 per 100 000 PY, respectively. PSC prevalence ranged 0-31.7 per 100 000 persons, with notable inter-regional differences. Mean age at PSC diagnosis was bimodally distributed, with relative peaks at 15 and 35 years. Mean concurrence of IBD with PSC was 50%, with 76% having ulcerative colitis, 17% Crohn's disease and 8% indeterminate/unspecified IBD. CONCLUSION While considerable heterogeneity exists in the geoepidemiology of PSC, overall, the classical dogmata of male predilection, bimodal distribution of mean age and high PSC-IBD concurrence appear to hold true. Despite a seemingly stable IR over time, further studies are needed to better understand the geoepidemiology of PSC.

Abstract
Autoimmune liver diseases are chronic inflammatory hepatobiliary disorders that when classically defined encompass three distinctive clinical presentations; primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH). Meaningful changes in disease epidemiology are reported, with increasing incidence and prevalence of AIH and PSC in Europe, and rising prevalence of PBC across Europe, North America and the Asia-Pacific region. However, there appears to be very significant global variation with contemporary incidence rates of disease per 100 000 ranging from 0.84 to 2.75 for PBC, 0.1 to 4.39 for PSC and 0.4 to 2.39 for AIH. Prevalence corresponds, and per 100 000 estimates for PBC range from 1.91 to 40.2, for PSC between 0.78 and 31.7 and for AIH from 4.8 to 42.9. Population-based studies and multicentre observational cohort series provide improved understanding of the clinical course that patients experience, highlighting variations in presenting phenotypes geographically and temporally. Collectively, while autoimmune liver diseases are rare, the clinical burden is disproportionately high relative to population incidence and prevalence. Age, sex and race also impact clinical outcomes, and patient morbidity and mortality are reflected by high need for gastroenterology, hepatology and organ transplant services.

Abstract
Cholestatic liver disease is a disease that causes liver damage and fibrosis owing to bile stasis. It is represented by primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC), but the pathophysiological pathways that cause bile stasis in both diseases are different. The pathogenesis of the disease is still unclear, although autoimmune mechanisms have been postulated and partially elucidated. Although the disease may progress slowly with only mild liver dysfunction, it may progress to liver cirrhosis or liver failure, which require liver transplantation. As a medical treatment, ursodeoxycholic acid is widely used for PBC and has proved to be very effective against disease progression in cases of PBC. On the other hand, its efficacy is limited in cases of PSC, and the research and development of various drugs are underway. Furthermore, the clinical course of both diseases is quite variable, making the design of clinical trials fairly difficult. In this review, we present the general natural history of PBC and PSC, and provide information on the latest drug therapies currently available and those that are under investigation.

Abstract
A diagnosis of primary sclerosing cholangitis (PSC) has been associated with increased risk of hepatobiliary cancers, colorectal cancer and all-cause mortality in several studies, while associations with cardiovascular disease have been inconsistent. We conducted a systematic review and meta-analysis of published cohort studies on the topic to summarize these associations. PubMed and Embase databases were searched up to January 13th, 2020. Cohort studies on PSC and risk of cancer, cardiovascular disease, or mortality were included. Summary relative risks (RRs) and 95% confidence intervals (95% CIs) were estimated using random effects models. The summary RR (95% CI) comparing persons with PSC to persons without PSC was 584.37 (269.42-1267.51, I2 = 89%, n = 4) for cholangiocarcinoma (CCA), 155.54 (125.34-193.02, I2 = 0%, n = 3) for hepatobiliary cancer, 30.22 (11.99-76.17, I2 = 0%, n = 2) for liver cancer, 16.92 (8.73-32.78, I2 = 88%, n = 4) for gastrointestinal cancer, 7.56 (2.42-23.62, I2 = 0%, n = 3) for pancreatic cancer, 6.10 (4.19-8.87, I2 = 14%, n = 7) for colorectal cancer (CRC), 4.13 (2.99-5.71, I2 = 80%, n = 5) for total cancer, 3.55 (2.94-4.28, I2 = 46%, n = 5) for all-cause mortality, and 1.57 (0.25-9.69, I2 = 79%, n = 2) for cardiovascular disease. Strong positive associations were observed between PSC and risk of CCA, hepatobiliary cancer, liver cancer, gastrointestinal cancer, pancreatic cancer, CRC, total cancer, and all-cause mortality, but not for cardiovascular disease.

Trends in Incidence of Autoimmune Liver Diseases and Increasing Incidence of Autoimmune Hepatitis. Clin Gastroenterol Hepatol 2021; 19:573-579.e1. [PMID: 32526342 DOI: 10.1016/j.cgh.2020.05.061] [Citation(s) in RCA: 51] [Impact Index Per Article: 12.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2019] [Revised: 05/19/2020] [Accepted: 05/29/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC) are autoimmune liver diseases of unknown etiology. We studied trends in incidences of AIH, PBC, and PSC in a population-based prospective study Canterbury, New Zealand. METHODS We collected data on patients with AIH (n = 99), PBC (n = 26), or PSC (n = 47) from public hospitals and private practices in Canterbury from 2008 through 2016. Diagnoses were made based on international standardized criteria. We calculated incidence rates for the time periods of 2008-2010, 2011-2013, and 2014-2016 and compared them using 2-tailed mid-P exact tests. RESULTS Overall incidence rates were 1.93 per 100,000 for AIH (95% CI, 1.58-2.34), 0.51 per 100,000 for PBC (95% CI, 0.33-0.73), and 0.92 per 100,000 for PSC (95% CI, 0.68-1.21). The incidence of AIH was significantly higher during the period of 2014-2016 (2.39 per 100,000; 95% CI, 1.76-3.23) than during the period of 2008-2010 (1.37 per 100,000; 95% CI, 0.91- 2.06) (P < .05). Incidences of PBC and PSC did not change significantly. In 2016, prevalence values were 27.4 per 100,000 for AIH (95% CI, 23.58-32.0), 9.33 per 100,000 for PBC (95% CI, 7.13-12.05), and 13.17 per 100,000 for PSC (95% CI, 10.56-16.42). CONCLUSIONS In a population-based prospective study, we found that the incidence of AIH was significantly higher in the 2014-2016 period than the 2008-2010 period; incidences of PBC and PSC were unchanged over the same period. Further studies are needed to determine the reasons for changes in incidence of autoimmune liver diseases.

Abstract
Primary sclerosing cholangitis is a rare disease with poor prognosis that potentially leads to liver cirrhosis and is often complicated by inflammatory bowel disease. Although ursodeoxycholic acid is the most commonly used drug to treat primary sclerosing cholangitis, its effectiveness in treating primary sclerosing cholangitis has not yet been established. An 11-year-old girl had a fever, upper and lower abdominal pain, and bloody stools. Colonoscopy revealed ulcerative colitis. She also had elevated hepatobiliary enzyme levels and C-reactive protein levels, indicating cholangitis after starting food intake, and primary sclerosing cholangitis was diagnosed with endoscopic retrograde cholangiography. Her hepatobiliary enzyme levels gradually improved after ursodeoxycholic acid was started, and symptoms did not recur after food intake. Primary sclerosing cholangitis should be considered if patients, even children, with inflammatory bowel disease, have upper abdominal pain with elevated biliary enzyme levels. The clinical guidelines for primary sclerosing cholangitis treatment have recommended that ursodeoxycholic acid should not be actively used. However, there are some recent reports stating its effectiveness for primary sclerosing cholangitis. In this patient, ursodeoxycholic acid may have been effective for the normalization of the hepatobiliary enzymes. However, it is unknown whether ursodeoxycholic acid improves long-term prognosis. Hence, further evidence regarding the effectiveness of ursodeoxycholic acid in the treatment of primary sclerosing cholangitis needs to be established.

Abstract
INTRODUCTION PBC registries in the UK focus on data from secondary care without clear coordinated contribution from primary care. The Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) receives data from > 500 primary care practices (PCPs). Notably, the Lancet commissioning group is extracting data from the RCGP RSC database to shape UK policy on liver disease. AIMS To create a novel ontology to facilitate PBC case finding from primary care provider (PCP) records. METHODS RCGP RSC data were collected from participating PCPs in the county of Surrey, UK. PBC diagnostic criteria of the AASLD and EASL guidelines were used to develop 725 data codes to facilitate patient record searches. A scoring system built into the ontology allowed categorization of cases as PBC definite, PBC probable, and PBC unlikely. RESULTS A total of 218,099 records were searched from participating PCPs. Of these, there were 58 PBC definite, 2317 PBC probable, and 215,724 PBC unlikely patients. There were 32 PBC definite patients who did not match to our regional PBC database and were henceforth included as new-found cases. Two of these cases were not labeled as PBC by the PCP. From the PBC unlikely group, 7/215,724 (0.003%) patients were labeled as PBC in secondary care records; however, none of them were coded as having PBC by their PCPs. CONCLUSIONS Utilization of the UK National RCGP RSC database supported by novel ontology score has successfully helped us identify (i) new cases of PBC not known to local/regional secondary care providers and (ii) de novo PBC cases. There are many PBC probable cases whose data merit further careful evaluation.

Effects of Primary Sclerosing Cholangitis on Risks of Cancer and Death in People With Inflammatory Bowel Disease, Based on Sex, Race, and Age. Gastroenterology 2020; 159:915-928. [PMID: 32445859 DOI: 10.1053/j.gastro.2020.05.049] [Citation(s) in RCA: 112] [Impact Index Per Article: 22.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Revised: 05/05/2020] [Accepted: 05/11/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND & AIMS There are insufficient population-level data on the effects of primary sclerosing cholangitis (PSC) in patients with inflammatory bowel disease (IBD). METHODS We identified incident cases of IBD, with PSC (PSC-IBD) and without, from April 2006 to April 2016 and collected data on outcomes through April 2019. We linked data from national health care registries maintained for all adults in England on hospital attendances, imaging and endoscopic evaluations, surgical procedures, cancer, and deaths. Our primary aim was to quantify the effects of developing PSC in patients with all subtypes of IBD and evaluate its effects on hepatopancreatobiliary disease, IBD-related outcomes, and all-cause mortality, according to sex, race, and age. RESULTS Over 10 years, we identified 284,560 incident cases of IBD nationwide; of these, 2588 patients developed PSC. In all, we captured 31,587 colectomies, 5608 colorectal cancers (CRCs) 6608 cholecystectomies, and 41,055 patient deaths. Development of PSC was associated with increased risk of death and CRC (hazard ratios [HRs], 3.20 and 2.43, respectively; P < .001) and a lower median age at CRC diagnosis (59 y vs 69 y without PSC; P < .001). Compared to patients with IBD alone, patients with PSC-IBD had a 4-fold higher risk of CRC if they received a diagnosis of IBD at an age younger than 40 years; there was no difference between groups for patients diagnosed with IBD at an age older than 60 years. Development of PSC also increased risks of cholangiocarcinoma (HR, 28.46), hepatocellular carcinoma (HR, 21.00), pancreatic cancer (HR, 5.26), and gallbladder cancer (HR, 9.19) (P < .001 for all). Risk of hepatopancreatobiliary cancer-related death was lower among patients with PSC-IBD who received annual imaging evaluations before their cancer diagnosis, compared to those who did not undergo imaging (HR, 0.43; P = .037). The greatest difference in mortality between the PSC-IBD alone group vs the IBD alone group was for patients younger than 40 years (incidence rate ratio >7), in contrast to those who received a diagnosis of IBD when older than 60 years (incidence rate ratio, <1.5). Among patients with PSC-IBD we observed 173 first liver transplants. Liver transplantation and PSC-related events accounted for approximately 75% of clinical events when patients received a diagnosis of PSC at an age younger than 40 years vs 31% of patients who received a diagnosis when older than 60 years (P < .001). African Caribbean heritage was associated with increased risks of liver transplantation or PSC-related death compared with white race (HR, 2.05; P < .001), whereas female sex was associated with reduced risk (HR, 0.74; P = .025). CONCLUSIONS In a 10-year, nationwide study, we confirmed that patients with PSC-IBD have increased risks of CRC, hepatopancreatobiliary cancers, and death compared to patients with IBD alone. In the PSC-IBD group, diagnosis of IBD at age younger than 40 years was associated with greater risks of CRC and all-cause mortality compared with diagnosis of IBD at older ages. Patients who receive a diagnosis of PSC at an age younger than 40 years, men, and patients of African Caribbean heritage have an increased incidence of PSC-related events.

Abstract
The liver is a critical organ in controlling immune tolerance. In particular, it is now clear that targeting antigens for presentation by antigen presenting cells in the liver can induce immune tolerance to either autoantigens from the liver itself or tissues outside of the liver. Here we review immune mechanisms active within the liver that contribute both to the control of infectious diseases and tolerance to self-antigens. Despite its extraordinary capacity for tolerance induction, the liver remains a target organ for autoimmune diseases. In this review, we compare and contrast known autoimmune diseases of the liver. Currently patients tend to receive strong immunosuppressive treatments and, in many cases, these treatments are associated with deleterious side effects, including a significantly higher risk of infection and associated health complications. We propose that, in future, antigen-specific immunotherapies are adopted for treatment of liver autoimmune diseases in order to avoid such adverse effects. We describe various therapeutic approaches that either are in or close to the clinic, highlight their mechanism of action and assess their suitability for treatment of autoimmune liver diseases.

Abstract
BACKGROUND & AIMS There are few population-based studies of the incidence and mortality of autoimmune hepatitis. The burden of the disease and how it has changed over time have not been fully explored. We conducted a population-based cohort study on the incidence and mortality of autoimmune hepatitis in England, 1997-2015. METHODS From the Clinical Practice Research Datalink we included 882 patients diagnosed with autoimmune hepatitis in England, 1997-2015. The patients were followed through 2015, and we calculated the sex- and age-standardized incidence and prevalence of autoimmune hepatitis. We examined variation in incidence by sex, age, calendar year, geographical region and socioeconomic status, and incidence rate ratios were calculated with Poisson regression. We calculated all-cause and cause-specific mortality. RESULTS The overall standardized incidence rate of autoimmune hepatitis was 2.08 (95% confidence interval 1.94-2.22) per 100,000 population per year, higher in women, higher in older age and independent of region and socioeconomic status. From 1997 to 2015 the incidence doubled from 1.27 (95% confidence interval 0.51-2.02) to 2.56 (95% confidence interval 1.79-3.33) per 100,000 population per year. The 10-year cumulative all-cause mortality was 31.9% (95% confidence interval 27.6-36.5), and the 10-year cumulative liver-related mortality, including hepatocellular carcinoma was ~10.5%. CONCLUSIONS This population-based study showed that the incidence of autoimmune hepatitis doubled over an eighteen-year period. The incidence was particularly high in older women and was similar across all regions of England and independent of socioeconomic status. Patients with autoimmune hepatitis had a high mortality.

Abstract
Primary sclerosing cholangitis (PSC) is a rare, immune-mediated, chronic cholestatic liver disease associated with a unique phenotype of inflammatory bowel disease that frequently manifests as pancolitis with right-sided predominance. Available data suggest a bidirectional interplay of the gut-liver axis with critical roles for the gastrointestinal microbiome and circulating bile acids (BAs) in the pathophysiology of PSC. BAs shape the gut microbiome, whereas gut microbes have the potential to alter BAs, and there are emerging data that alterations of BAs and the microbiome are not simply a consequence but the cause of PSC. Clustering of PSC in families may suggest that PSC occurs in genetically susceptible individuals. After exposure to an environmental trigger (e.g., microbial byproducts or BAs), an aberrant or exaggerated cholangiocyte-induced immune cascade occurs, ultimately leading to bile duct damage and progressive fibrosis. The pathophysiology can be conceptualized as a triad of (1) gut dysbiosis, (2) altered BA metabolism, and (3) immune-mediated biliary injury. Immune activation seems to be central to the disease process, but immunosuppression does not improve clinical outcomes or alter the natural history of PSC. Currently, orthoptic liver transplantation is the only established life-saving treatment, whereas antimicrobial therapy or fecal transplantation is an emerging therapeutic option for PSC. The beneficial effects of these microbiome-based therapies are likely mediated by a shift of the gut microbiome with favorable effects on BA metabolism. In the future, personalized approaches will allow to better target the interdependence between microbiome, immune function, and BA metabolism and potentially cure patients with PSC.

Abstract
BACKGROUND Contemporary primary sclerosing cholangitis (PSC) population-based cohorts describing the epidemiology, natural history, and long-term fluctuations in serum alkaline phosphatase (SAP) and their prognostic relevance are lacking. Therefore, we investigated the incidence and natural history of PSC and quantified SAP fluctuations among those with PSC in Olmsted County, Minnesota over the last 41 years. METHODS The Rochester Epidemiology Project was used to identify 56 subjects diagnosed with PSC between 1976 and 2017 in Olmsted County. The primary endpoint (n = 19) included liver transplantation, hepatic decompensation, and cholangiocarcinoma. RESULTS The age- and sex-adjusted incidence of PSC (per 100,000 person years) nearly doubled from 2001 to 2017 compared to 1976-2000 (1.47; 95% CI 0.99-1.96 versus 0.79; 95% CI 0.42-1.16, p = 0.02). This increase paralleled a rise in patients with markers of a milder phenotype at the time of diagnosis: normal SAP (26.32% versus 0%, p < 0.01) and lower Mayo PSC risk score [0.36 (- 0.57 to 1.55) versus - 0.50 (- 1.25 to 0.35), p = 0.03]. Intra-individual SAP fluctuates with a median coefficient of variation of 36.20%. SAP normalization and dropping below 1.5 × upper limit of normal (ULN) occurs at a rate of 5% and 10% per year, respectively. SAP less than 1.5 × ULN was associated with a lower risk of PSC-related complications (hazard ratio 0.11; 95% CI 0.03-0.42). CONCLUSIONS The patients with PSC are increasingly being diagnosed with a milder phenotype. While a lower SAP is associated with improved outcomes, the high intra-individual variation of SAP levels calls into question the practice of using a single SAP value as a surrogate endpoint in clinical trials.

Abstract
Introduction: Studies on the epidemiology of primary sclerosing cholangitis (PSC) are mainly based on tertiary referral centers; and are retrospective case series susceptible to selection bias. The aim of this study was to estimate incidence; survival and cause of mortality of PSC in Italy; using population-based data. Methods: Data collected from the National Rare Diseases Registry (RNMR) and the National Mortality Database (NMD) were integrated and analyzed. Results: We identified 502 PSC incident cases. The crude incidence rate between 2012 and 2014 was 0.10 per 100,000 individuals. Sixty percent were male; mean age at disease onset and at diagnosis were 33 and 37 years; respectively; highlighting a mean diagnostic delay of 4 years. The rate of interregional mobility was 12%. Ten-year survival was 92%. In 32% of cases the cause of death was biliary-related; 12% died of biliary or gallbladder cancer. Conclusions: For rare diseases such as PSC; population-based cohort’s studies are of paramount importance. Incidence rates of PSC in Italy are markedly lower and survival much longer than the ones reported from tertiary; single-centre series. Moreover; the diagnostic delay and the patient interregional mobility highlights the need for increasing awareness on the disease and for resource reallocation among Italian regions within the National Health Service

Abstract
Primary sclerosing cholangitis (PSC) is a chronic, progressive, hepatobiliary disease characterized by inflammation and fibrosis of the intra- and extra-hepatic bile ducts. Its natural history is one that generally progresses towards cirrhosis, liver failure, cholangiocarcinoma, and ultimately disease-related death, with a median liver transplantation-free survival time of approximately 15-20 years. However, despite its lethal nature, PSC remains a heterogenous disease with significant variability in outcomes amongst different regions of the world. There are also many regions where the outcomes of PSC have not been studied, limiting the overall understanding of this disease worldwide. In this review, we present the geoepidemiologic variations in outcomes of PSC, with a focus on survival pre- and post-liver transplantation as well as the concurrence of inflammatory bowel disease and hepatobiliary neoplasia.

Abstract
Sclerosing cholangitis (SC) is defined as a condition with progressive stenosis and destruction of the bile ducts due to diffuse inflammation and fibrosis and currently includes three categories: primary sclerosing cholangitis (PSC), secondary cholangitis, and IgG4-related sclerosing cholangitis (IgG4-SC). SC categories share similar clinical features, such as cholestasis. Patients with SC present with cholestatic symptoms, including jaundice and pruritus, and blood tests reveal elevation of cholestatic enzymes. Cholangiography, endoscopic or magnetic, is inevitably required for making a diagnosis. Although the presentation of IgG4-SC and PSC are similar, the comorbidities, treatment response, and outcomes differ significantly, and therefore, it is strongly advisable to be familiar with these two diseases to make a correct diagnosis. Differentiation of cholangiocarcinoma from IgG4-SC and PSC is also extremely important. In this review, the clinical characteristics, comorbidities, treatment and outcomes of IgG4-SC and PSC will be outlined based on experience mainly from Japan.

Abstract
AIM Autoimmune liver diseases (AILD) including autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC) impose a significant burden on public health, and it is important to estimate their prevalence. We carried out a nationwide, hospital-based, epidemiological survey of AIH, PBC, and PSC, and compared the results with those from previous surveys. METHOD We randomly selected health-care facilities used in the survey from a list of all facilities in Japan. The selection rate was determined according to a stratification based on the facility characteristics and scale. We sent questionnaires to the selected facilities enquiring about the number and sex of patients with AILD who visited the facility in 2016. An identical survey was undertaken for AIH/PBC in 2004 and for PSC in 2007; we carried out a comparative analysis of these data. RESULTS We selected 1793 departments from health centers all over Japan. Of them, 1078 (60.1%) responded to the questionnaires. The number of reported patients with AIH, PBC, and PSC was 8505, 10 847, and 906, respectively, and point prevalence was 23.9 (95% confidence interval, 23.3-24.5) for AIH (8.7 in 2004), 33.8 (33.0-34.6) for PBC (11.6 in 2004), and 1.80 (1.75-1.85) for PSC (0.95 in 2007) per 100 000 population. Male-to-female patient ratio of AILD was 1:4.3 for AIH (1:6.9 in 2004), 1:3.9 for PBC (1:7.1 in 2004), and 1:0.88 for PSC (1:1.4 in 2007). CONCLUSION The current study indicates an increasing trend of prevalence as well as male-to-female patient ratio of AILD in Japan.

Abstract
Autoimmune liver disease (AILD) is a group of autoimmune-mediated hepatobiliary injuries, including autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis. It has been demonstrated that gene susceptibility, molecular mimicry, and abnormal immune regulation networks contribute to the occurrence and progression of AILD, while the mechanism of the related abnormal immune environment remains undetermined. It is currently believed that autoimmune diseases are mainly caused by the destruction of autoimmune tolerance mechanisms. Regulatory T cell (Treg), as a key factor to peripheral immune tolerance, may play a critical role in AILD. This article aims to elucidate the pathogenesis of AILD from the perspective of Treg cells and provide insight into the application of Treg cells in the therapy of AILD.

Abstract
BACKGROUND & AIMS Primary sclerosing cholangitis (PSC) is a fibrostenosing disease of the bile ducts associated with inflammatory bowel disease (IBD), for which the only treatment is liver transplantation. PSC progression has been defined in cohorts from referral centers or single-nation population databases. However, observations made from these cohorts have limited applicability owing to referral bias and demographic confounders. We analyzed data from the worldwide PSC Partners Patient Registry, an international online database established in 2014 to obtain information from individuals with PSC or their caretakers and compare symptoms, disease progression, and treatments of PSC in the United States and other countries. METHODS We analyzed demographic and clinical characteristics, symptoms, and clinical outcomes of patients with PSC using the PSC Partners Patient Registry. Participants completed an online standardized questionnaire and electronic case report, providing information on age, age at symptom onset, age at PSC diagnosis, methods of diagnosis, concurrent diagnoses, family history, and medication use. RESULTS Of 873 registrants, 811 (92.9%) had completed questionnaires and 528 (65.1%) had their PSC diagnosis confirmed; we found no significant demographic or clinical differences between patients with vs without a confirmed diagnosis. In contrast to other studies, we found a higher proportion of individuals with PSC to be female (52.5%). However, the mean age at PSC diagnosis (32.4 ± 14.7 y) and the proportion of individuals with PSC and IBD (67.1%) were similar to those from prior reports. Most cases in the database were from the United States (74.9%). More than half of the participants reported having pruritus, abdominal pain, fatigue, or sleep disturbances; rates were not significantly different among participants within vs outside the United States. There was no significant difference in treatment with ursodeoxycholic acid between participants within vs outside the United States (50.0% and 57.8%; P = .07). The median time of transplant-free survival was 21 years; transplant-free survival was associated with female sex and Crohn's disease. CONCLUSIONS Our findings from an analysis of data from the PSC Partners Patient Registry confirm those from previous studies, although we found a higher proportion of individuals with PSC to be female. In addition to allowing efficient collection of patient-reported outcomes, the patient-driven registry allows for inclusion of previously under-represented cases of PSC.

Abstract
Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease characterized by progressive fibroinflammatory destruction of the intra- and/or extrahepatic biliary ducts. While its features and disease course can be variable, most patients with PSC have concurrent inflammatory bowel disease and will eventually develop liver cirrhosis and end-stage liver disease, with liver transplantation representing the only potentially curative option. Importantly, PSC is associated with a significantly increased risk of malignancy compared to the general population, mainly cholangiocarcinoma, gallbladder carcinoma, hepatocellular carcinoma, and colorectal cancer, with nearly 50% of deaths in patients with PSC being due to cancer. Therefore, robust surveillance strategies are needed, though uncertainty remains regarding how to best do so. In this review, we discuss the epidemiology, prevention, and surveillance of cancers in patients with PSC. Where evidence is limited, we present pragmatic approaches based on currently available data and expert opinion.

Abstract
BACKGROUND Primary sclerosing cholangitis (PSC) is relatively rare disease and pathogenesis and methods of treatments were still not established. Then, we had conducted the making clinical guidelines to manage patients with PSC based on the literature review and expert opinions. These clinical guidelines were made for the medical doctors on the management of PSC, except child case of PSC. METHODS We had employed modified Delphi method. The production committee decided guidelines, strength of recommendations and evidence level after reviewed literatures systematically, and The Expert panel evaluated those. The Scientific Committee of the Japan Biliary Association (JBA) evaluated revised guidelines, and the Public comments were collected on web site of JBA. RESULTS We had made 16 guidelines about epidemiology/pathophysiology, diagnostics, therapy and prognosis. Also, we had made both diagnostic and therapeutic flow chart. CONCLUSIONS We hope that these guidelines will contribute to the improvement and development of the medical care of PSC.

Abstract
BACKGROUND & AIMS The rarity of autoimmune liver disease poses challenges to epidemiology studies. However, waitlists for liver transplantation can be used to study patients with end-stage liver diseases. We used these waitlists to assess trends in numbers and demographics of patients awaiting liver transplant for primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC), or autoimmune hepatitis (AIH). METHODS We collected data from UK and US national registries for all adults on liver transplant waitlists, from January 1, 1995, through December 31, 2014. We analyzed data from patients with PBC (n = 1434 in the United Kingdom and n = 5598 in the United States), PSC (n = 1093 in the United Kingdom and n = 6820 in the United States), and AIH (n = 538 in the United Kingdom and n = 4949 in the United States). Numbers of listings per year were adjusted to the estimated populations during each year. Regression analyses were used to examine trends and comparative statistics were used to evaluate differences in individual characteristics among groups. RESULTS Over the total study period, listings for PBC were 1.2 and 1.0 per million population per year in the United Kingdom and United States, respectively; for PSC, 0.9 and 1.2 per million population per year; and for AIH, 0.5 and 0.8 per million population per year. Over the period studied, numbers of listings for PBC decreased by 50% in both countries; changes in numbers of listings for PSC and AIH were smaller and not consistent between countries. By 2014, PSC had become the leading indication for liver transplantation among patients with autoimmune liver diseases in both countries. Median patient ages at time of listing were lower than those reported as median age of diagnosis for AIH and PBC. The ratio of women:men with PBC decreased by almost 50% from 1995 through 2014. Men with PSC were placed on the waitlist with higher disease severity scores than women in both countries. Among patients with PBC, those of black race were under-represented on waitlists from both countries. Among patients with PSC, Hispanics were under-represented on waitlists in the United States. Patients of non-white races were placed on waitlists at younger ages for all diseases; age differences in waitlist placement varied by up to 10 years, depending on race, among patients with PBC. CONCLUSIONS In an analysis of data collected from UK and US national liver transplant registries over 20 years, we found that PSC has become the leading indication for liver transplantation among patients with autoimmune liver diseases. Numbers of patients with PBC placed on waitlists, and the ratio of women:men with PBC, each decreased by almost 50%, possibly due to increased treatment with ursodeoxycholic acid. Within groups of patients on the transplant waitlist for PBC, PSC, or AIH, we found differences in age, sex, disease severity scores, and ethnicity between diseases and countries that require further study.

Abstract
Primary sclerosing cholangitis (PSC) is a rare, chronic, cholestatic liver disease of uncertain etiology characterized biochemically by cholestasis and histologically and cholangiographically by fibro-obliterative inflammation of the bile ducts. In a clinically significant proportion of patients, PSC progresses to cirrhosis, end-stage liver disease, and/or hepatobiliary cancer, though the disease course can be highly variable. Despite clinical trials of numerous pharmacotherapies over several decades, safe and effective medical therapy remains to be established. Liver transplantation is an option for select patients with severe complications of PSC, and its outcomes are generally favorable. Periodic surveillance testing for pre- as well as post-transplant patients is a cornerstone of preventive care and health maintenance. Here we provide an overview of PSC including its epidemiology, etiopathogenesis, clinical features, associated disorders, surveillance, and emerging potential therapies.

Abstract
AIM Primary sclerosing cholangitis (PSC) is a rare cholestatic disease. We previously reported the effects of bezafibrate on elevated hepatobiliary enzyme levels in patients with this disease both retrospectively and prospectively. In this study, we assessed factors predictive of bezafibrate efficacy. METHODS Twenty-five patients with PSC, who underwent bezafibrate therapy (400 mg per day) from November 2006 to June 2015, were evaluated. Treatment was judged as being effective if the levels of all of the hepatobiliary enzymes decreased after 12 weeks. We investigated the patients' characteristics, disease history, concomitant medications, liver function, and liver stiffness. RESULTS The efficacy rate of bezafibrate was 60% (15/25 patients). The efficacy rate in patients graded as Child-Pugh class A was significantly higher (75% [15/20]) than that in patients graded as class B (0% [0/5], P < 0.01). Non-responders had higher liver stiffness values (18.0 vs. 8.8 kPa, P = 0.19), and concomitantly used ursodeoxycholic acid more frequently (100% vs. 73%, P = 0.12) than responders. CONCLUSIONS We could not elucidate the factors predictive for bezafibrate efficacy for the treatment of PSC. However, bezafibrate was more effective for patients with preserved liver function (Child-Pugh class A) when it was prescribed before progression of liver fibrosis and failure of ursodeoxycholic acid therapy.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease which is associated with inflammatory bowel disease (IBD) in most cases. As there is currently no medical therapy which alters the natural history of PSC, liver transplantation may be required. Areas covered: We searched for articles in PubMed and critically reviewed current literature on the interrelationship between PSC and IBD with a specific focus on considerations for patients in the liver transplant setting. Expert commentary: PSC is an uncommon disease which limits available studies to be either retrospective or contain relatively small numbers of patients. Based on observations from these studies, the behavior and complications of PSC and IBD impact on each other both before and after a liver transplant. Both these autoimmune conditions and their associated cancer risk also influence patient selection for transplantation and may be impacted by immunosuppression use post-transplant. Hence, a complex interplay exists between PSC, IBD and liver transplantation which requires clarification with ongoing research.

Abstract
BACKGROUND AND AIMS Cholangiocarcinoma is a rare but devastating malignancy associated with a poor prognosis and a high mortality rate. With the recent advances in detection and treatment, it is unclear if the incidence and outcomes of cholangiocarcinoma are improving in the United States. The aim of this study was to evaluate the trends in the incidence, costs and mortality rates of cholangiocarcinoma- related hospital admissions in the USA. METHODS We utilized the National Inpatient Sample Database (NIS) from 1997-2012 for all patients in whom cholangiocarcinoma (ICD-9 code 155.1, 156) was the principal discharge diagnosis. The temporal trends in the number of hospital admissions, length of stay and, hospitalization costs along with mortality rates over the study period were determined by using regression analysis for trends. RESULTS There was a significant increase in the number of hospital admissions for cholangiocarcinoma as the principal diagnosis from 1997 to 2012 (10 357 vs 11 970, P<0.001). The mean length of stay for cholangiocarcinoma decreased by 17 % between 1997 and 2012 from 9.5 days to 7.9 days (P<0.001). However, during the same period, the mean hospital charges per patient (adjusted for inflation) increased 113.25% from $36 460 in 1997 to $77 753 in 2012. The in-hospital mortality rate decreased from 9.3% in 1997 to 6.4% in 2012 (P<0.001). CONCLUSIONS There was a significant increase in the number of hospital admissions and associated costs from cholangiocarcinoma in the USA between 1997 and 2012. However, this was accompanied by a decrease in the inpatient mortality rates from cholangiocarcinoma.

Abstract
Primary sclerosing cholangitis (PSC) is a rare obliterative fibrotic condition of the bile ducts. We assessed PSC epidemiology and natural history within the UK Clinical Practice Research Datalink (CPRD).Incidence and natural history of PSC were evaluated in a retrospective cohort study using linkage of CPRD, Hospital Episode Statistics, and Office for National Statistics data. Data from age, sex, and general practice-matched population controls provided a context for the incident PSC patients. Liver disease other than PSC was defined as autoimmune hepatitis, hepatitis, hepatomegaly, liver failure, cirrhosis, portal hypertension, cholangiocarcinoma, or hepatobiliary cancer.The age-standardized incidence of PSC was 0.68 (95% confidence interval [CI] 0.45-0.99) per 100,000 person-years and the age-standardized prevalence was 5.58 (95% CI 4.82-7.35) per 100,000 during 1998 to 2014. In all, 250 incident PSC patients met the inclusion criteria and each was matched with 5 controls (mean age 54 ± 18 years, men 63.2%). A higher percentage of PSC patients had a history of inflammatory bowel disease (54% vs 2%) and liver disease other than PSC (22% vs 1%) than controls (standardized differenceweighted >0.1). During a median follow-up of 5 years, PSC patients were more likely to develop adverse health outcomes. The mortality rate per 1000 person-years was 3-fold higher in PSC than population controls (49.5 vs 16.1; incidence rate ratio 3.1, 95% CI 2.2-4.2).The incidence and prevalence of PSC observed in the UK CPRD were either comparable with or higher than previous studies. Compared with the general population, PSC patients had worse health outcomes including PSC disease progression, complications, and higher mortality.

Abstract
BACKGROUND & AIMS Epidemiological data on primary sclerosing cholangitis (PSC) outside the Northern hemisphere are limited. Similarly, the impact of inflammatory bowel disease (IBD) on PSC outcomes remains unclear. We aimed to study the epidemiology and outcomes of PSC patients with and without IBD in an Australian cohort. METHODS We retrospectively studied PSC patients attending two tertiary referral hospitals over 20 years. Diagnosis of PSC was made according to international guidelines by positive cholangiography and/or liver biopsy (for small duct PSC) with supporting clinical and laboratory evidence. RESULTS Of 208 PSC patients (61% male) were studied (2271patient-years follow-up). The median age of PSC diagnosis was similar for PSC-IBD and PSC-only patients (40 years vs 42 years, P = .35). All 33 deaths occurred in PSC-IBD patients while there were no deaths in PSC-only patients (21% vs 0%, P < .01). However, there were no significant differences in liver transplantation (PSC-only 25% vs PSC-IBD 31%, P = .45) and transplant-free survival between PSC-only and PSC-IBD patients (P = .43). On multivariate Cox regression, only elevated international normalized ratio (INR) was associated with a greater risk of death or liver transplant (HR 2.0, 95% CI 1.1-3.6, P = .02). Development of gastrointestinal malignancy was higher in the PSC-IBD group compared to PSC-only group (22% vs 2%, P < .01). CONCLUSION Australian PSC patients have similar characteristics compared to European and North American cohorts. IBD is a significant predictor of gastrointestinal malignancies. Deaths were more common in PSC-IBD but overall transplant-free survival remained similar in PSC-IBD and PSC-only groups. An elevated INR was an independent predictor of death or liver transplantation.

Abstract
PURPOSE OF REVIEW Primary sclerosing cholangitis (PSC) is a rare, idiopathic biliary disease often with an insidious onset, variable disease course, and premature death related to benign and malignant PSC-related sequelae. This review aims to discuss the epidemiology, clinical variants, and natural history of PSC, incorporating data from recent population-based studies. RECENT FINDINGS PSC naturally leads to cirrhosis, cholangiocarcinoma, other hepatobiliary malignancies, dominant strictures, hepatic osteodystrophy, and bacterial cholangitis. The incidence of PSC appears to be increasing, the reasons for which are unclear. The time from diagnosis to liver transplant appears to be longer in more recent studies compared with earlier studies, suggesting a better overall prognosis than previously believed. In addition, with an increasing number of patients undergoing liver transplantation for PSC, the frequency of death because of liver failure has decreased, whereas cancer-related deaths have increased among patients with PSC. SUMMARY PSC is a heterogeneous disease with a variety of clinical outcomes, both fatal and nonfatal. The progression of liver fibrosis in an individual patient is difficult to predict and may vary from a relatively benign, nonprogressive form to a rapidly progressive form with the need for liver transplantation.

Abstract
Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease characterized by chronic inflammation of the biliary tree resulting in liver fibrosis. PSC is more common in male less than 40 years of age. The diagnosis of PSC is based on clinical, laboratory, image, and histological findings. A biochemical profile of mild to severe chronic cholestasis can be observed. Endoscopic retrograde cholangiography is the golden standard method for diagnosis, but magnetic resonance cholangiography is currently also considered a first-line method of investigation. Differences in clinical and laboratory findings were observed in young patients, including higher incidence of overlap syndromes, mostly with autoimmune hepatitis, higher serum levels of aminotransferases and gamma-glutamyl transferase, and lower incidence of serious complications as cholangiocarcinoma. In spite of the detection of several HLA variants as associated factors in large multicenter cohorts of adult patients, the exact role and pathways of these susceptibility genes remain to be determined in pediatric population. In addition, the literature supports a role for an altered immune response to pathogens in the pathogenesis of PSC. This phenomenon contributes to abnormal immune system activation and perpetuation of the inflammatory process. In this article, we review the role of immune and genetic factors in the pathogenesis of PSC in pediatric patients.

Abstract
OBJECTIVE Primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC), autoimmune hepatitis (AIH) and immunoglobulin G4 related cholangitis represent the major autoimmune liver diseases (AILD). However, the relationship between AILD incidence and socioeconomic development levels is yet to be explored. RESULTS A total of 43 studies were included. There was a positive but not significant correlation between the PBC incidence and HDI on a global level (r=0.348, P=0.082). However, in Europe, a significantly positive correlation existed between the PBC incidence and HDI (r=0.455, P=0.044). No statistical correlation between PSC incidence and HDI was observed (r=0.116, P=0.706). The incidence of AIH revealed a positive correlation with the national HDI both globally (r=0.638, P=0.014) and in Europe (r=0.644, P=0.045). Moreover, the PBC incidence demonstrated a positive correlation with the health index (r=0.422, P=0.036), but a negative correlation with the education index (r= -0.650, P<0.01). Moreover, the income index presented a positive correlation with both the PSC incidence (r=0.599, P=0.031) and the AIH incidence (r=0.649, P=0.012). METHODS PubMed was searched to identify relevant epidemiological studies on AILD. The human development index (HDI) was applied as an indicator for socioeconomic development. HDI data were obtained and calculated based on the 2014 Human Development Report. Pearson coefficient and linear regression analysis were conducted to estimate the correlation between incidence and HDI. CONCLUSIONS There is positive association between the national incidence of AILD and the socioeconomic status, as measured by HDI. In less-developed countries, the incidence of AILD, especially PBC and AIH, might be less common.
