HCC represents the sixth most common cancer worldwide and the second leading cause of cancer-related death. Despite the high incidence, treatment options for advanced HCC remain limited and unsuccessful, resulting in a poor prognosis. Despite the major advances achieved in the diagnostic management of HCC, only one third of the newly diagnosed patients are presently eligible for curative treatments. Advances in technology and an increased understanding of HCC biology have led to the discovery of novel biomarkers...

BACKGROUND: Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are forms of hepatic autoimmunity, and risk for both diseases has a strong genetic component. This study aimed to define the genetic architecture of PBC and PSC within the Polish population. METHODS: Subjects were 443 women with PBC, 120 patients with PSC, and 934 healthy controls recruited from Gastroenterology Departments in various Polish hospitals. Allelotyping employed a pooled-DNA sample-based genome-wide association study (GWAS) approach, using Illumina Human Omni2...

: The etiopathogenesis of primary sclerosing cholangitis (PSC) is unknown. Genetic variants of fucosyltransferase 2 (FUT2) have been identified in genome-wide association studies as risk factor for PSC. We investigated the role of Fut2 in murine liver pathophysiology by studying Fut2(-/-) mice. Fut2(-/-) mice were viable and fertile, had lower body weight than wild type (wt) littermates and grey fur, as described earlier. Half of the Fut2(-/-) mice showed serum bile salt levels 40 times higher than wt (Fut2(-/-)(high) ), whereas the remainder were normocholanemic (Fut2(-/-)(low) )...

Primary sclerosing cholangitis (PSC) is a cholestatic liver disease of unknown etiopathogenesis characterized by fibrous cholangiopathy of large and small bile ducts. Systemic administration of a murine TNF-related apoptosis-inducing ligand (TRAIL) receptor agonist induces a sclerosing cholangitis injury in C57BL/6 mice, suggesting endogenous TRAIL may contribute to sclerosing cholangitis syndromes. Cellular inhibitor of apoptosis proteins (cIAP-1 and cIAP-2) are negative regulators of inflammation and TRAIL receptor signaling...

Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are the most frequent chronic cholestatic liver diseases and serve as model diseases to discuss the management of cholestasis in 2017 in the lecture that is summarized in this report. PBC and PSC are characterized by inflammation and fibrosis of small intrahepatic (PBC) or larger intra- and/or extrahepatic (PSC) bile ducts. Bile duct damage leads to cholestasis and can progress to liver fibrosis and even cirrhosis. Various genetic, environmental and endogenous factors may contribute to the development of chronic cholestatic liver diseases, but the exact pathogenesis of PBC and PSC has not been clarified...

BACKGROUND AND AIMS: The molecular, endoscopic, and histological features of IBD-associated CRC differ from sporadic CRC. The objective of this study was to describe the prevalence, clinical features, and prognosis of IBD-associated CRC compared to patients with sporadic CRC in a US statewide population-based cohort. METHODS: All newly diagnosed cases of CRC between 1996 and 2011 were obtained from Utah Cancer Registry. IBD was identified using a previously validated algorithm, from statewide databases of Intermountain Healthcare, University of Utah Health Sciences, and the Utah Population Database...

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...

PURPOSE OF REVIEW: Alterations of the gut-liver axis have been linked to the pathogenesis of primary sclerosing cholangitis (PSC) since the disease was first described. The purpose of this review is to discuss multiple recent studies on the intestinal microbiota in human PSC and experimental models of this disease. RECENT FINDINGS: Data are available from eight cross-sectional studies of human PSC, which include a variable number of patients (n = 11-85), material (mucosal or fecal), and microbiota profiling methodology...

Malignancy represents substantial morbidity and mortality in patients with primary sclerosing cholangitis (PSC). This subset of patients has been proven to be at increased risk for developing cholangiocarcinoma, gallbladder carcinoma, and colorectal cancer in those with overlapping inflammatory bowel disease. Herein we review the prevalence of these malignancies and recommend screening tools and current knowledge to reduce the disease burden in this population. Cholangiocarcinoma is the most dominant malignancy affecting PSC patients, with a lifetime risk ranging from 5-20%...

: Liver retransplantation in patients with primary sclerosing cholangitis (PSC) has not been well studied. The aims of this study were to characterize patients with PSC listed for and undergoing retransplantation and to describe the outcomes in these patients. The United Network for Organ Sharing/Organ Procurement and Transplantation Network database was used to identify all primary liver transplantations and subsequent relistings and first retransplantations in adults with PSC between 1987 and 2015...

BACKGROUND & AIMS: Patients with ulcerative colitis (UC) have an increased risk of rectal cancer, so reconstruction with an ileal pouch anal anastomosis (IPAA) is generally preferred to an ileo-rectal anastomosis (IRA) after subtotal colectomy. Similarly, completion proctectomy is recommended for patients with ileostomy and diverted rectum, although this approach has been questioned because anti-inflammatory agents might reduce cancer risk. We performed a national cohort study in Sweden to assess the risk of rectal cancer in patients with UC who have an IRA, IPAA, or diverted rectum after subtotal colectomy...

BACKGROUND AND AIMS: The risk of colorectal cancer (CRC) in various chronic liver diseases compared with the general population remains unclear. We performed a systematic review and meta-analysis to assess the risk of CRC in patients with chronic liver diseases before and after liver transplantation. METHODS: Electronic databases were searched for studies assessing the risk of CRC in patients with chronic liver diseases. The primary outcome was the pooled risk of CRC among studies that reported the risk as standardized incidence rate (SIR)...

Pathogenesis of primary sclerosing cholangitis (PSC) may involve impaired bile acid (BA) homeostasis. We analyzed expressions of factors mediating enterohepatic circulation of BA using ileal and colonic (ascending and sigmoid) biopsies obtained from patients with PSC with and without ulcerative colitis (UC) and explanted PSC livers. Two-fold increase of BA-activated farnesoid X receptor (FXR) protein levels were seen in ascending and sigmoid colon of PSC patients with correspondingly decreased apical sodium-dependent BA transporter (ASBT) gene expression...

Autoimmune hepatitis (AIH) is an uncommon, chronic inflammatory, and relapsing liver disease of unknown origin that may lead to liver cirrhosis, hepatocellular carcinoma, liver transplantation, or death. AIH occurs in all age groups and races but can frequently manifest as acute fulminant hepatitis. Clinical presentation of AIH can have features similar to primary sclerosing cholangitis (PSC) and primary biliary cirrhosis (PBC), and these diseases may coexist leading to overlap syndromes. Although histological diagnosis is necessary, imaging features often can demonstrate characteristics that may be helpful to distinguish these diseases...

Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease with detrimental sequela. In many patients, PSC progresses to end-stage liver disease and hepatobiliary cancer. There is no medical therapy that is proven to halt or reverse the progression of PSC. Approximately 70 to 80% of PSC patients have inflammatory bowel disease, usually ulcerative colitis. The etiology of PSC is poorly understood. Several lines of evidence suggest that the intestinal microbiota plays an important role in the etiopathogenesis of PSC...
