Abstract
Unlike in normal cells, ursodeoxycholic acid (UDCA) causes apoptosis rather than protection in cancer cells. Aim of this study was to demonstrate whether UDCA actually inhibits proliferation and induces apoptosis in bile duct cancer cells; the effect of UDCA on the expression of COX-2, PI3K/AKT, ERK, and EGFR; how UDCA affects cancer cell invasiveness and metastasis, since these effects are not established in bile duct cancer cells. SNU-245 cells (human extrahepatic bile duct cancer cells) were cultured. MTT assays were performed to evaluate the effect of UDCA on the cell proliferation. A cell death detection enzyme-linked immunosorbent assay and a caspase-3 activity assay were used to determine apoptosis. Western blot analysis measured expression levels of various proteins. The invasiveness of the cancer cells was evaluated by invasion assay. In cultured bile duct cancer cells, UDCA suppressed cell proliferation in bile duct cancer cells by inducing apoptosis and p53 activation, blocking deoxycholic acid (DCA)-induced activated EGFR-ERK signaling and COX-2, inhibiting DCA-induced activated PI3K-AKT signaling, and suppressing the invasiveness of bile duct cancer cells. In addition, a MEK inhibitor impaired UDCA-induced apoptosis in bile duct cancer cells. UDCA has antineoplastic and apoptotic effects in bile duct cancer cells. Thus, UDCA could be a chemopreventive agent in patients with a high risk of cancer, and/or a therapeutic option that enhances other chemotherapeutics.

Abstract
Cholangiocarcinoma (CCA) is the most common malignancy in patients with primary sclerosing cholangitis (PSC) and carries a high rate of mortality. Although the pathogenesis of CCA in PSC is largely unknown, inflammation-driven carcinogenesis concomitant with various genetic and epigenetic abnormalities are underlying factors. The majority of CCA cases develop from a dominant stricture (DS), which is defined as a stricture with a diameter < 1.5 mm in the common bile duct or < 1.0 mm in the hepatic duct. In PSC patients presenting with an abrupt aggravation of jaundice, pain, fatigue, pruritus, weight loss, or worsening liver biochemistries, CCA should be suspected and evaluated utilizing a variety of diagnostic modalities. However, early recognition of CCA in PSC remains a major challenge. Importantly, 30-50% of CCA in PSC patients are observed within the first year following the diagnosis of PSC followed by an annual incidence ranging from 0.5 to 1.5 per 100 persons, which is nearly 10 to 1000 times higher than that in the general population. Cumulative 5-year, 10-year, and lifetime incidences are 7%, 8-11%, and 9-20%, respectively. When PSC-associated CCA is diagnosed, most tumors are unresectable, and no effective medications are available. Given the poor therapeutic outcome, the surveillance and management of PSC patients who are at an increased risk of developing CCA are of importance. Such patients include older males with large-duct PSC and possibly concurrent ulcerative colitis. Thus, more attention should be paid to patients with these clinical features, in particular within the first year after PSC diagnosis. In contrast, CCA is less frequently observed in pediatric or female PSC patients or in those with small-duct PSC or concurrent Crohn's disease. Recently, new biomarkers such as antibodies to glycoprotein 2 have been found to be associated with an increased risk of developing CCA in PSC. Herein, we review the literature on the pathogenesis, incidence, clinical features, and risk factors, with a focus on various diagnostic modalities of PSC-associated CCA.

Abstract
These guidelines on the management of primary sclerosing cholangitis (PSC) were commissioned by the British Society of Gastroenterology liver section. The guideline writing committee included medical representatives from hepatology and gastroenterology groups as well as patient representatives from PSC Support. The guidelines aim to support general physicians, gastroenterologists and surgeons in managing adults with PSC or those presenting with similar cholangiopathies which may mimic PSC, such as IgG4 sclerosing cholangitis. It also acts as a reference for patients with PSC to help them understand their own management. Quality of evidence is presented using the AGREE II format. Guidance is meant to be used as a reference rather than for rigid protocol-based care as we understand that management of patients often requires individual patient-centred considerations.

Abstract
Cholestatic liver diseases (CLDs) encompass a variety of disorders of bile formation and/or flow which generally result in progressive hepatobiliary injury and ultimately end-stage liver disease. Many patients with CLD are diagnosed between the ages of 20-50 years, a particularly productive period of life professionally, biologically and in other respects; it is not surprising, thus, that CLD is often associated with impaired health-related quality of life (HRQOL) and uncertainty regarding implications for and outcomes of pregnancy. Primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC) are the most prominent CLDs, both having considerable morbidity and mortality and representing major indications for liver transplantation. These disorders, as a consequence of their complications (eg ascites, hepatic osteodystrophy), associated conditions (eg inflammatory bowel disease) and symptoms (eg pruritus and fatigue), can significantly impair an array of domains of HRQOL. Here we review these impactful clinical aspects of PSC and PBC as well as the topics of fertility and pregnancy.

Abstract
Primary sclerosing cholangitis is the classic hepatobiliary manifestation of inflammatory bowel disease and is generally chronic and progressive. Patients frequently present with asymptomatic, anicteric cholestasis, but many develop progressive biliary strictures with time, leading to recurrent cholangitis, biliary cirrhosis, and end-stage liver disease. Medical treatment does not slow the progression of disease, and many patients need liver transplantation, after which recurrent disease is a risk. The increased incidence of hepatobiliary cancer, which is not related to the underlying severity of biliary fibrosis, is of particular concern. Risk of colorectal cancer is also increased in patients with coexistent inflammatory bowel disease. Mechanistic insights have arisen from studies of secondary sclerosing cholangitis, in which a similar clinical profile is associated with a specific cause, and genomic studies have elucidated potential disease-initiating pathways in the primary form. The close association between inflammatory bowel disease and primary sclerosing cholangitis underscores the need to further understand the role of environmental factors in generation of lymphocytes that are postulated to be retargeted, deleteriously, to the biliary tree. Treatment of primary sclerosing cholangitis is confined to supportive measures, but advances in pathobiology suggest that new stratified approaches will soon be available.

Abstract
Autoimmune liver disease spans three predominant processes, from the interface hepatitis of autoimmune hepatitis to the lymphocytic cholangitis of primary biliary cirrhosis, and finally the obstructive fibrosing sclerotic cholangiopathy of primary sclerosing cholangitis. Although all autoimmune in origin, they differ in their epidemiology, presentation and response to immunosuppressive therapy and bile acid based treatments. With an ongoing better appreciation of disease aetiology and pathogenesis, treatment is set ultimately to become more rational. We provide an overview of current and future therapies for patients with autoimmune liver disease, with an emphasis placed on some of the evidence that drives current practice.

Abstract
Primary sclerosing cholangitis (PSC) is a progressive, cholestatic disorder characterised by chronic inflammation and stricture formation of the biliary tree. Symptoms include pruritus, fatigue and in advanced cases ascending cholangitis, cirrhosis and end-stage hepatic failure. Patients are at an increased risk of malignancy arising from the bile ducts, gallbladder, liver and colon. The majority (>80%) of Northern European patients with PSC also have inflammatory bowel disease (IBD), usually ulcerative colitis (UC). IBD commonly presents before the onset of PSC, although the opposite can occur and the onset of both conditions can be separated by many years. The colitis associated with PSC is characteristically mild although frequently involves the whole colon. Despite the majority of patients having relatively inactive colonic disease, paradoxically the risk of colorectal malignancy is substantially increased. Patients may also develop dominant, stenotic lesions of the biliary tree which may be difficult to differentiate from cholangiocarcinoma and the coexistence of IBD may influence the development of this complication. Ursodeoxycholic acid may offer a chemoprotective effect against colorectal malignancy and improve liver biochemical indices. Evidence of any beneficial effect on histological progression of hepatobiliary disease is less clear. High doses (∼25-30 mg/kg/d) may be harmful and should be avoided. Autoimmune hepatitis (AIH) is less common in patients with IBD than PSC, however, an association has been observed. A small subgroup may have an overlap syndrome between AIH and PSC and management should be individualised dependant on liver histology, serum immunoglobulin levels, autoantibodies, degree of biochemical cholestasis and cholangiography.

Abstract
Primary sclerosing cholangitis (PSC) is a rare and complex chronic cholestatic liver disease, and its management is hindered by a very poor understanding of its pathogenesis. Endogenous bile acids are likely to play a role either directly or indirectly in the pathogenesis and/or progression of PSC ('toxic-bile'hypothesis). At present, no medical therapies have been proven to delay disease progression. Ursodeoxycholic acid (UDCA) is the agent that has received the most attention. Based on large randomized studies, it appears that UDCA at doses from 13 to 23 mg/kg/d has no proven benefit on survival, but is well tolerated and improves serum liver tests and surrogate markers of prognosis whereas, at higher doses (28-30 mg/kg/d), it is associated with a worsened outcome. However, except at very high doses and despite the controversies, many hepatologists still consider UDCA a reasonable treatment choice. Indeed, its use at dosages of 15-20 mg/kg/d has recently been approved for the treatment of PSC by the French National Health Authority. In addition, 24-nor-ursodeoxycholic acid, a side-chain-modified UDCA derivative, has shown promising results in animal models of PSC and is currently under investigation in humans.

Abstract
While many therapeutic agents have been evaluated in Primary Sclerosing Cholangitis (PSC), none have been shown in controlled trials to modify the course of disease. The bile acid ursodeoxycholic acid (UDCA) has been widely used in the treatment of PSC but its use remains controversial. It may have a role in providing chemoprotection against the development of colonic dysplasia/cancer in patients with associated inflammatory bowel disease. The exclusion of IgG4-associated cholangitis, which generally responds to immunosuppressant agents, is essential prior to deciding on an appropriate therapeutic strategy in PSC. In the absence of proven therapeutic agents, treatment strategies are usually aimed at minimizing the complications of the biliary disease. Endoscopic management of dominant strictures may improve long-term outcomes. Orthotopic liver transplantation has a good outcome in patients with end stage PSC.

Abstract
Intrahepatic cholangiocarcinoma (ICC) is one of the life-threatening complications of primary sclerosing cholangitis (PSC). However, the incidence of ICC in Japanese PSC patients is low, and the association between the development of ICC and morbidity duration of PSC is largely unknown. Here, we describe a case of ICC that developed after a long-term follow-up of a patient with PSC and ulcerative colitis (UC). At the age of 10 years, the patient was first diagnosed with UC and its remission was achieved with systemic steroid therapy. Since then, he was routinely followed-up. At the age of 19 years, laboratory tests showed abnormalities in liver function parameters, and the patient was diagnosed with PSC. Although treatment with ursodeoxycholic acid improved the abnormalities in serum levels of biliary enzymes and no PSC-related symptoms were seen for 13 years, calculous cholecystitis frequently occurred in the patient since the age of 32 years. He developed ICC, which expressed some hepatic progenitor cell markers such as CD133, neural cell adhesion molecule, keratin 7, and keratin 19 at the age of 33 years. ICC was treated by curative partial hepatectomy and adjuvant chemotherapy with gemcitabine. Eight months later, however, the patient developed multiple metastases in the abdominal lymph nodes and lungs, and died 21 months after the onset of ICC. Here, we report a case of ICC that developed after a 14-year follow-up of a patient with PSC and UC.

Abstract
BACKGROUND Patients with PSC and IBD have a high incidence of colonic carcinomas (CRC), and the annual incidence of CRC increases with duration of disease. UDCA treatment has been suggested to reduce colonic dysplasias and carcinomas. AIMS The annual incidence of colorectal carcinomas after long-term UDCA treatment was studied. METHODS Patients included in a prospective study on the outcome after ursodeoxycholic acid (UDCA) treatment were evaluated. RESULTS A total of 120 of 171 PSC patients included had IBD (108 UC and 12 CD). All patients were treated with UDCA for a median time of 6.7 years. Seven patients with PSC and IBD developed a CRC yielding a prevalence of 5.8%. In years 0-3 (n = 120) after the start of UDCA, the annual incidence rate of CRC was 0.62/100 patient years; in years 3-6 (n = 93) it increased to 1.28 and decreased thereafter in years 6-9 (n = 67) to 1.17, then in years 9-12 (n = 42) to 0 and after >12 years (n = 24) it remained 0. In PSC with IBD, Kaplan-Meier estimate of CRC formation increased with time in the first years of treatment and reached a plateau after 9 years; after treatment for ≥ 9 years, no further CRC were observed. CONCLUSION After the start of UDCA, the annual incidence of CRC increased up to 6 years and subsequently decreased. In PSC with IBD treated with UDCA, most colonic carcinomas develop in the first years after the start of treatment.

Abstract
Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease mainly affecting young male patients. PSC is characterised by chronic inflammation and fibrotic strictures of the intra- and extrahepatic biliary system, which eventually lead to cholestasis and biliary cirrhosis. However, the clinical course remains very variable. As the aetiology remains unknown, the development of a causative treatment is challenging and today no specific medical therapy is available. Ursodeoxycholic acid has been widely used for the treatment of PSC, but improved only biochemistry and/or symptoms in low- or medium dosages and is probably harmful in higher dosages. Other drugs such as immunosuppressive, antifibrotic or antibiotic agents have not been proven to be effective in large clinical trials. The endoscopic therapy encompasses balloon-dilatation and/or stenting of strictures, relieves clinical symptoms and improves a cholestatic enzyme profile. However, endoscopic therapy is limited to patients in advanced stages of PSC with biliary obstruction.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic liver condition which may affect both intra and extrahepatic biliary tree. Etiology of PSC remains to be fully elucidated but genetic, autoimmune, inflammatory and possibly infective factors could all contribute to its development. More than two-thirds of patients are males and the most commonly associated condition is an inflammatory bowel disease which occurs in up to 70% of affected subjects. Endoscopic cholangiopancreatography (ERCP) and magnetic resonanse cholangiopancreatography (MRCP) remain a gold standard in the diagnosis of this condition. No curative treatment of PSC exists and a proportion of patients who develop liver failure or suffer from recurrent episodes of cholangitis requires liver transplantation. PSC is associated with increased risk of malignancies, in particular cholangiocarcinoma which may arise in 12% of patients. The main aim of this chapter is to review the current knowledge on pathogenesis and clinical aspects of PSC as well as its associated malignancies.

Abstract
BACKGROUND Ursodeoxycholic acid (UDCA) in a dose of 28-30 mg/kg/day increases the likelihood of clinical deterioration of primary sclerosing cholangitis (PSC) patients. AIM To compare the risk of adverse clinical endpoints in patients with varying disease status. METHODS We reviewed records from patients previously enrolled in a study evaluating the effects of high dose (28-30 mg/kg/day) UDCA in PSC. Patients were grouped according to treatment (UDCA vs. placebo) and baseline disease status (histological stage of PSC, total serum bilirubin). Development of clinical endpoints including death, liver transplantation, cirrhosis, oesophageal varices and cholangiocarcinoma was sought. RESULTS A total of 150 patients were included of whom 49 patients developed endpoints. There was an increased development of endpoints among patients using UDCA vs. placebo (14 vs. 4, P=0.0151) with early histological disease (stage 1-2, n=88) but not with late stage (stage 3-4, n=62) disease (17 vs. 14, P=0.2031). Occurrence of clinical endpoints was also higher in patients receiving UDCA vs. placebo (16 vs. 2, P=0.0008) with normal bilirubin levels (total bilirubin ≤1.0 mg/dL) but not in patients with elevated bilirubin levels (15 vs. 16, P=0.6018). Among patients not reaching endpoints 31.7% had normalisation of their alkaline phosphatase levels when compared to 14.3% in patients who reached endpoints (P=0.073). CONCLUSION The increased risk of adverse events with UDCA treatment when compared with placebo is only apparent in patients with early histological stage disease or normal total bilirubin.

Abstract
BACKGROUND Primary sclerosing cholangitis (PSC) remains a challenging disease to manage. The main goals are prevention of disease progression and reduction of the increased cancer risk. AIMS To review the management strategies for PSC and its variant forms based on published studies. METHODS Publications were identified using Pubmed, Medline and Ovid search engines. RESULTS Distinguishing PSC from variants, such as IgG4-associated cholangitis, and overlap with autoimmune hepatitis is essential to guide treatment decisions. There is no proven efficacious medical treatment for PSC. Ursodeoxycholic acid has been disappointing in low and moderate doses, and potentially dangerous in higher doses, although its role and optimal dose in chemoprevention requires investigation. The novel bile acid, 24-norursodeoxycholic acid, has shown promise in mouse models; human trials are in progress. Dominant strictures are optimally managed by dilatation and stenting to relieve obstructive complications, although exclusion of biliary malignancy is essential. Liver transplantation is the only proven therapy for those with advanced disease. Cholangiocarcinoma remains the most unpredictable and feared complication. In highly selected groups, neo-adjuvant chemoradiation with liver transplantation seems promising, but requires further validation. Screening for inflammatory bowel disease and surveillance for colorectal carcinoma should not be overlooked. CONCLUSIONS The effective management of PSC and its variants is hindered by uncertainties regarding pathogenesis of disease and factors responsible for its progression. Genome studies may help to identify further targets for drug therapy and factors leading to malignant transformation.

Abstract
BACKGROUND & AIMS In patients with primary sclerosing cholangitis (PSC) treated with ursodeoxycholic acid (UDCA), dominant stenoses are associated with reduced survival free of liver transplantation and the role of inflammatory bowel disease (IBD) in such patients is unclear. In the present study the influence of IBD on the outcome in patients with and without dominant stenosis has been evaluated. METHODS In a prospective study, 171 patients were followed for up to 20 years. All patients were treated with ursodeoxycholic acid; patients with dominant stenosis in addition were treated endoscopically. RESULTS A total of 97 out of 171 patients had or developed dominant bile duct stenoses and 96 out of 97 were treated endoscopically. In patients with dominant stenosis without IBD, no carcinoma was found whereas all six bile duct and two gallbladder carcinomas and 6/7 colo-rectal carcinomas were found in patients with dominant stenosis with IBD (p=0.012). In patients without dominant stenosis but with IBD, 1 out of 7 had colo-rectal carcinoma. In patients with dominant stenosis without IBD (n=30), actuarial survival free of liver transplantation at 18 years was 77.8% and in those with dominant stenosis and inflammatory bowel disease (n=67) it was 23.0% (p=0.045). In PSC patients without dominant stenosis and without IBD (n=21), actuarial survival free of liver transplantation at 18 years was 68.2% and in those with inflammatory bowel disease (n=53) it was 78.4% (n.s.). CONCLUSIONS In patients without dominant stenosis, IBD had no effect on the incidence of carcinomas and survival. Only patients with dominant stenosis with additional IBD had an increased carcinoma rate. This may contribute to the reduced survival free of liver transplantation in such patients.

Abstract
Primary sclerosing cholangitis is a cholestatic liver disease characterized by inflammation and fibrosis of intra-/extrahepatic bile ducts, leading to multifocal strictures. Primary sclerosing cholangitis exhibits a progressive course resulting in cirrhosis and the need for liver transplantation over a median period of 12 years. The disease is frequently associated with inflammatory bowel disease and carries an increased risk of colorectal cancer and cholangiocarcinoma. Despite extensive research, there is currently no effective medical treatment. Multiple drugs are shown to be ineffective in halting disease progression, including ursodeoxycholic acid, the most widely evaluated drug. High-dose ursodeoxycholic acid (28-30 mg/kg/day) was recently shown to increase the adverse events rate. Endoscopic or radiological dilatation of a 'dominant' stricture may lead to symptomatic and biochemical improvement. However, liver transplantation is the only life-prolonging treatment for patients with end-stage disease. Studies with promising drugs, such as antibiotics, antifibrotic agents and bile acid derivatives, are eagerly awaited.

Abstract
BACKGROUND/AIMS Primary sclerosing cholangitis (PSC) is a rare disease, and large-scale report of PSC in France is lacking. We initiated a prospective multisite observational study. METHODS One hundred and fifty PSC patients (90 with associated inflammatory bowel disease) were included. At entry, 11 patients had a diagnosis of hepatobiliary or colon malignancy (cholangiocarcinoma: n = 5, hepatocellular carcinoma: n = 2, gallbladder carcinoma: n = 1 and colorectal cancer: n = 4). One hundred and forty-one patients (94%) were treated with ursodeoxycholic acid (UDCA) (median dose: 13.1 mg/kg/day), including 118 with UDCA started before inclusion. RESULTS During follow-up [3.9 (0.1-7.2) years], colorectal cancer was diagnosed in four patients and biliary carcinoma in two (incidences: 0.76 and 0.38 for 100 patient-years, respectively). Kaplan-Meier transplant-free survival at 4 years was 79%. Main causes of death (n = 10) were cancer (n = 5, including three colorectal cancers and two cholangiocarcinoma) or liver failure (n = 4). Indications for transplantation (n = 25) were end-stage liver disease (n = 16), biliary cancer (known or suspected) (n = 5), recurrent acute cholangitis (n = 3) or pruritus (n = 1). Independent predictive factors of death or transplantation were alkaline phosphatase at least 3 upper limit of normal values, platelets less than or equal to 150000/mm3 and bilirubin at least 23 micromol/l. Observed and predicted survivals were similar. CONCLUSION PSC in France shares common features with other series and is almost universally treated with UDCA. Under standard-dose UDCA, PSC remains a rather severe disease. However, the low incidence of cholangiocarcinoma is compatible with a potential chemoprotective effect of UDCA against biliary neoplasia development.

Abstract
Early studies in primary sclerosing cholangitis (PSC) were concerned with disease characterization, and were followed by epidemiological studies of PSC and clinical subsets of PSC as well as a large number of treatment trials. Recently, the molecular pathogenesis and the practical handling of the patients have received increasing attention. In the present review we aim to give an update on the pathogenesis of PSC and cholangiocarcinoma in PSC, as well as to discuss the current opinion on diagnosis and treatment of PSC in light of the recent European Association for the Study of the Liver and the American Association for the Study of Liver Diseases practice guidelines.

Abstract
Bile salts have a crucial role in hepatobiliary and intestinal homeostasis and digestion. Primary bile salts are synthesized by the liver from cholesterol, and may be modified by the intestinal flora to form secondary and tertiary bile salts. Bile salts are efficiently reabsorbed from the intestinal lumen to undergo enterohepatic circulation. In addition to their function as a surfactant involved in the absorption of dietary lipids and fat-soluble vitamins bile salts are potent signaling molecules in both the liver and intestine. Under physiological conditions the bile salt pool is tightly regulated, but the adaptive capacity may fall short under cholestatic conditions. Elevated serum and tissue levels of potentially toxic hydrophobic bile salts during cholestasis may cause mitochondrial damage, apoptosis or necrosis in susceptible cell types. Therapeutic nontoxic bile salts may restore impaired hepatobiliary secretion in cholestatic disorders. The hydrophilic bile salt ursodeoxycholate is today regarded as the effective standard treatment of primary biliary cirrhosis and intrahepatic cholestasis of pregnancy, and is implicated for use in various other cholestatic conditions. Novel therapeutic bile salts that are currently under evaluation may also prove valuable in the treatment of these diseases.

Abstract
PURPOSE OF REVIEW Primary sclerosing cholangitis (PSC) is being diagnosed with increasing frequency. The most feared complication is the presence or development of cholangiocarcinoma (CCA). The present review summarizes recent data with regards to diagnosis, pathobiology and treatment. RECENT FINDINGS Several investigations have focused on aspects of the molecular biology of CCA in general; such data should be explored now in the context of PSC-related CCA to yield new diagnostic markers and approaches for therapy. SUMMARY CCA has to be suspected in any new PSC patient presenting with jaundice. Exploration should include carbohydrate antigen19-9 and two imaging techniques. Endoscopic cholangioscopy might become very rewarding. Important progress has been achieved in liver transplantation by the use of preoperative radio-chemotherapy. Molecular biology points to inflammation-induced cytokines with mutagenic action and to the relevance of extracellular matrix proteins for invasion but also for proliferation. Micro-RNAs prove to be very important in the control of cell proliferation, differentiation and apoptosis. Mutated p53, cyclins, wnt/beta-catenin signaling, proliferation indices, mucins, carbohydrate antigen19-9, CRP and aneuploidy appear to hold significant potential as predictors of outcome in CCA. It is expected that the further unraveling of these molecular processes will ultimately lead to development of tests allowing early diagnosis and to development of medical approaches to retard tumor formation or recurrence following surgical interventions.

Abstract
Primary sclerosing cholangitis is characterized by progressive fibrosing obliteration of the biliary tract. In some cases the disease is restricted to the small bile ducts, but most patients develop fibrotic stenoses of the larger bile ducts. Despite advances in magnetic resonance cholangiography, in unclear cases endoscopic retrograde cholangiography is necessary to make the correct diagnosis. In patients with total or subtotal strictures of the large bile ducts, these so-called dominant stenoses may be treated by endoscopic balloon dilatation and/or stent placement, though in the large majority of cases a stent placement is not necessary. Several studies showed an improvement of biochemical parameters after endoscopic treatment, and actuarial survival in these patients was improved compared with predicted survival. Endoscopic retrograde cholangiography allows tissue sampling, brush cytology, and bile analysis for early detection of cholangiocarcinoma, a major complication of primary sclerosing cholangitis. Despite successful endoscopic opening of bile duct stenoses, patients often progress to liver failure, leading to liver transplantation as the treatment of choice.

Abstract
BACKGROUND Primary sclerosing cholangitis is characterized by progressive fibrotic inflammation and obliteration of intra- and/or extrahepatic bile ducts. Total or subtotal stenoses of major bile ducts are associated with reduced survival. OBJECTIVE To evaluate the outcome after long-term endoscopic treatment. DESIGN Prospective, single-center study. SETTING Tertiary care academic medical center. PATIENTS A total of 171 patients treated with ursodeoxycholic acid were followed for as long as 20 years. At entry, 20 patients had dominant stenoses, and during a median follow-up period of 7.1 years, dominant stenosis developed in another 77. INTERVENTIONS Ninety-six patients with dominant stenoses were treated by repeated balloon dilation; 5 patients with complete obstruction with bacterial cholangitis were stented. MAIN OUTCOME MEASUREMENTS Survival free of liver transplantation, number of procedures, complications. RESULTS In total, 500 balloon dilations were performed and 5 stents were placed. Complications were pancreatitis (2.2%), bacterial cholangitis (1.4%), and bile duct perforation (0.2%); there were no deaths. Repeated endoscopic interventions allowed the preservation of a functioning common bile duct and of at least 1 hepatic duct up to 2 cm above the bifurcation in all patients. Progression of intrahepatic bile duct and liver disease led to the need for liver transplantation in 22 of 96 patients. Five years after the first dilation of a dominant stenosis, the survival free of liver transplantation rate was 81%, and after 10 years, it was 52%. LIMITATIONS Single-center study, no control group, primary end-stage liver disease excluded. CONCLUSION Repeated endoscopic balloon dilations of dominant stenoses allow the preservation of a functioning common bile duct for many years.

Abstract
AIMS The effect of ursodeoxycholic acid (UDCA) treatment on survival and liver histological progression of primary sclerosing cholangitis (PSC) remains uncertain. The aim of the present study was to evaluate the effect and safety of UDCA in PSC. METHODS Electronic databases including Medline, Embase, Cochrane controlled trials register, Web of Science and PubMed (updated to January 2009) and manual bibliographical searches were carried out. A meta-analysis of all randomized controlled trials (RCT) comparing UDCA with placebo or no treatment was carried out. RESULTS Eight RCT including 465 patients were assessed. UDCA could significantly improve liver biochemistry, but had no effect on pruritus and fatigue. Meta-analysis of the included RCT showed UDCA had no significant effect on the incidence of death, liver transplantation, and death and/or liver transplantation. However, a significant difference for the incidence of histological improvement was found between the two groups (odds ratio [OR], 9.19; 95% CI: 0.98, 86.15; P = 0.05). Meta-analysis also indicated a reduction trend of histological deterioration and an improvement trend of cholangiographic changes. These trends were constant in the sensitivity analyses. CONCLUSION The meta-analysis found that UDCA can improve liver biochemistry and there is a trend towards improvement in liver histology and cholangiography, but has no effect on survival free of transplantation.

Abstract
Multiple bile duct hamartomas (BDHs)/von Meyenburg complexes, are tumor-like lesions of the liver. Malignant transformation in BDHs has been previously reported in very rare instances, and the most common tumor arising in this clinical setting is cholangiocarcinoma. Herein, we report on clinicopathological findings in two cases of cholangiocarcinoma occurring in liver with multiple BDHs. Histopathologically, multiple BDHs showed morphologic transition from clearly benign to dysplasia or carcinoma in situ, then to invasive carcinoma sequence of the biliary epithelium. The neoplastic epithelium showed positivity for cytokeratin 19, CA 19-9, and epithelial membrane antigen. Staining for Hep Par 1, alpha-fetoprotein, cytokeratin 20, and alpha1-antitrypsin was negative. All sections from the non-neoplastic liver in each specimen showed multiple BDHs. Any other clinically detectable primary tumor was not found. These two neoplasms were interpreted as a cholangiocarcinoma arising in BDHs. This suggested BDHs might be a risk factor of development of cholangiocarcinoma.

Abstract
BACKGROUND & AIMS Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by inflammation and progressive bile duct fibrosis. There are limited data on pediatric PSC. METHODS We performed a retrospective chart review of 47 pediatric patients with PSC. RESULTS The mean age at diagnosis was 11 +/- 4.9 years. Symptoms occurred before presentation in 81% of patients; inflammatory bowel disease was found in 59% and autoimmune hepatitis (overlap syndrome) in 25% of patients. Magnetic resonance cholangiography revealed both extrahepatic and intrahepatic, isolated intrahepatic, isolated extrahepatic, and no biliary involvement (small-duct PSC) in 40%, 14%, 10%, and 36%, respectively. Advanced fibrosis (stage >II) was present in 65%. Colonoscopy revealed pancolitis, rectal sparing, and normal findings in 24%, 24%, and 18%, respectively. All patients were treated with ursodeoxycholic acid (UDCA); 9 with overlap syndrome also received immunosuppressants. Fifteen patients without overlap syndrome had positive autoimmune markers and responded to UDCA monotherapy. Liver transplantation was performed in 9 patients (3 with overlap syndrome and 2 with small-duct PSC) at a median time of 7 years after diagnosis. The 10-year posttransplant survival rate was 89%. CONCLUSIONS In one of the largest single-center studies of children with PSC, we found that most children with PSC had inflammatory bowel disease or autoimmune overlap and advanced fibrosis at diagnosis. Levels of alanine aminotransferase and gamma-glutamyl transferase were highest in patients with overlap syndrome and lowest in those with small-duct PSC. Levels of serum liver enzymes normalized after therapy with UDCA, including patients with positive autoimmune markers without histologic features of autoimmune hepatitis.

Abstract
Therapeutic strategies for autoimmune liver diseases are increasingly established. Although proportionately uncommon, specialist centers have with time refined the best approaches for each disease, based on an improved understanding of the spectrum of presentation. The major treatment aims are to prevent end-stage liver disease and its associated complications. As a result of drugs such as ursodeoxycholic acid, predniso(lo)ne and azathioprine, both primary biliary cirrhosis and autoimmune hepatitis are now less commonly indications for liver transplantation. Unfortunately, the same inroads in treatment efficacy have as yet not been made for primary sclerosing cholangitis, although the recognition that a subset of patients may have a treatable secondary sclerosing cholangitis (IgG4 related) is helping a proportion. With better biological understanding, more specific interventions are expected that will benefit all those with autoimmune liver diseases.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by inflammation and fibrosis of the bile ducts, resulting in end-stage liver disease and reduced life expectancy. PSC primarily affects young and middle-aged men, often in association with underlying inflammatory bowel disease. The etiology of PSC includes immune-mediated components and elements of undefined nature. A cholestatic picture of liver biochemistries with elevations in serum alkaline phosphatase, nonspecific autoantibodies such as perinuclear antineutrophilic antibody, antinuclear antibodies and smooth muscle antibodies, and diffuse multifocal biliary strictures, resulting in a 'beaded' appearance on radiographic studies, are the hallmarks of the disease. No effective medical therapy is currently available, although clinical studies are in progress. Ursodeoxycholic acid at high doses (28 mg/kg/day to 30 mg/kg/day) is the most promising agent but is unproven so far. Liver transplantation is currently the only life-extending therapy for patients with end-stage disease, although recurrent disease can be observed in the transplanted liver. The multiple complications of PSC include pruritus, fatigue, vitamin deficiencies, metabolic bone disease, peristomal varices, bacterial cholangitis, dominant biliary strictures, gallbladder stones and polyps, and malignancy, particularly cholangiocarcinoma, which is the most lethal complication of PSC.

Abstract
Autoinflammatory liver disease represents an important aspect of global hepatological practice. The three principal disease divisions recognized are autoimmune hepatitis, primary sclerosing cholangitis and primary biliary cirrhosis. Largely, but not exclusively, these diseases are considered to be autoimmune in origin. Increased recognition of outlier and overlap syndromes, changes in presentation and natural history, as well as the increased awareness of IgG4-associated sclerosing cholangitis, all highlight the limitations of the classic terminology. New insights continue to improve the care given to patients, and have arisen from carefully conducted clinical studies, therapeutic trials, as well as genetic and laboratory investigations. The challenges remain to treat patients before liver injury becomes permanent and to prevent the development of organ failure.

Abstract
Primary sclerosing cholangitis is a chronic cholestatic liver disease characterized by inflammation and fibrosis of the bile ducts, resulting in cirrhosis and need for liver transplantation and reduced life expectancy. The majority of cases occur in young and middle-aged men, often in association with inflammatory bowel disease. The etiology of primary sclerosing cholangitis includes immune-mediated components and elements of undefined nature. No effective medical therapy has been identified. The multiple complications of primary sclerosing cholangitis include metabolic bone disease, dominant strictures, bacterial cholangitis, and malignancy, particularly cholangiocarcinoma, which is the most lethal complication of primary sclerosing cholangitis. Liver transplantation is currently the only life-extending therapeutic alternative for patients with end-stage disease, although recurrence in the allografted liver has been described. A PSC-like variant attracting attention is cholangitis marked by raised levels of the immunoglobulin G4 subclass, prominence of plasma cells within the lesions, and steroid responsiveness.

Abstract
PURPOSE OF REVIEW Primary sclerosing cholangitis is a chronic cholestatic liver disease characterized by strictures of the biliary tree complicated by cirrhosis and cholangiocarcinoma. It is immune mediated, although the precise aetiology remains unknown. RECENT FINDINGS The research into aetiology, genetic associations, pathogenesis, epidemiology, diagnosis of cholangiocarcinoma and medical treatments are discussed. SUMMARY Multiple gene polymorphisms and human leucocyte antigen haplotype associations with primary sclerosing cholangitis have been investigated. Common inflammatory bowel disease associated polymorphisms and ulcerative colitis associated human leucocyte antigen haplotypes are not associated with primary sclerosing cholangitis. Biliary epithelial cells may mediate their own destruction by exaggerating innate and adaptive immune responses to bacterial products in the liver. The natural history of large and small duct primary sclerosing cholangitis has been reviewed. Positron emission tomography may be a useful adjunct to current imaging modalities in the pretransplant assessment of patients to exclude cholangiocarcinoma. Ursodeoxycholic acid remains the most studied medical treatment for primary sclerosing cholangitis; pilot studies suggest a possible role for tacrolimus and silymarin, however further studies are required.
