Hypomotility is a common symptom of gallstone disease, which is accompanied by a loss of interstitial Cajal-like cells (ICLCs) in the gallbladder. Ursodeoxycholic acid (UDCA) is widely used in treating gallstone disease, and has shown anti-apoptotic and anti-inflammatory effects apart from its ability to dissolve gallstones. In this study, we investigated the anti-apoptotic and anti-inflammatory effects of UDCA on ICLCs in guinea pigs with gallstones. Guinea pigs were fed a high-cholesterol diet for 8 weeks to induce the formation of gallstones...

NI-0801 is a fully human monoclonal antibody against chemokine (C-X-C motif) ligand 10 (CXCL10), which is involved in the recruitment of inflammatory T cells into the liver. The safety and efficacy of NI-0801 was assessed in patients with primary biliary cholangitis. In this open-label phase 2a study, patients with primary biliary cholangitis with an inadequate response to ursodeoxycholic acid received six consecutive intravenous administrations of NI-0801 (10 mg/kg) every 2 weeks. Patients were followed up for 3 months after the last infusion...

Primary biliary cholangitis (PBC) is a rare chronic cholestatic liver disease that may progress to biliary cirrhosis if left untreated. The first-line therapy for PBC is ursodeoxycholic acid (UDCA). Unfortunately, 1 of 3 patients does not respond to UDCA. These patients are at risk for developing clinical events, including cirrhosis, complications of portal hypertension, hepatocellular carcinoma, liver transplant, or death. Recently, the U.S. Food and Drug Administration approved obeticholic acid to be used in certain patients with PBC...

While bile acids are important for both digestion and signaling, hydrophobic bile acids can be harmful especially when in high concentrations. Mechanisms for protection of cholangiocytes against bile acid cytotoxicity include negative feedback loops via farnesoid X nuclear receptor (FXR) activation, the bicarbonate umbrella, cholehepatic shunting and anti-inflammatory signaling, among others. By altering or overwhelming these defense mechanisms, cholestatic diseases such as primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) can further progress to biliary cirrhosis, end-stage liver disease and death or liver transplantation...

REVIEW
Raul S Gonzalez, Kay Washington
Primary biliary cholangitis and autoimmune hepatitis are common autoimmune diseases of the liver. Both have typical clinical presentations, including certain autoantibodies on serologic testing. Histologic features are also often typical: primary biliary cholangitis shows bile duct destruction (sometimes with granulomas), and autoimmune hepatitis shows prominent portal and lobular lymphoplasmacytic inflammation. Both have a wide differential diagnosis, including one another; they may also simultaneously occur within the same patient...

BACKGROUND: Dogs are fed various diets, which also include components of animal origin. In humans, a high-fat/low-fibre diet is associated with higher faecal levels of bile acids, which can influence intestinal health. It is unknown how an animal-based diet high in fat and low in fibre influences the faecal bile acid levels and intestinal health in dogs. This study investigated the effects of high intake of minced beef on the faecal bile acid profile in healthy, adult, client-owned dogs (n = 8) in a 7-week trial...

BACKGROUND: primary biliary cholangitis (PBC) patients with a suboptimal response to ursodeoxycholic acid (UDCA) have a significantly worse survival rate. Fenofibrate has been shown to improve the short-term biochemical response in this group of patients. However, there is limited data available on the safety and efficacy of its long-term use, especially in patients with cirrhosis. Methods:in this retrospective cohort study, fenofibrate was given to PBC patients with a suboptimal response to at least 12 months of UDCA (13-15 mg/kg/d) therapy...

BACKGROUND: Primary Biliary Cholangitis (PBC, formerly cirrhosis), is a chronic cholestatic liver disease which until spring 2016 had a single licensed therapy, Ursodeoxycholic acid (UDCA). Approximately 30% of patients do not respond to UDCA, and are high-risk for progressing to end stage liver disease, transplantation or death. A new era of stratified medicine with second-line therapies to treat high-risk disease is emerging, with the first such second-line agent obeticholic acid recently receiving FDA and EMA approval and entering practice...

BACKGROUND & AIMS: MAF bZIP transcription factor G (MAFG) is activated by the farnesoid X receptor (FXR) to repress bile acid synthesis. However, expression of MAFG increases during cholestatic liver injury in mice and in cholangiocarcinomas. MAFG interacts directly with methionine adenosyltransferase 1A (MAT1A) and other transcription factors at the E-box element to repress transcription. We studied mechanisms of MAFG upregulation in cholestatic tissues and the pathways by which S-adenosylmethionine (SAMe) and ursodeoxycholic acid (UDCA) prevent the increase in MAFG expression...

BACKGROUND: In a recent study we had evidence that sulphite oxidase (SO) may be a relevant autoantigen in primary sclerosing cholangitis (PSC). Aim of the present study was, therefore, to analyse humoral and cellular immune-reactivity towards SO in these patients in more detail. METHODS: Sera from 53 patients with PSC (30 untreated and 23 treated with ursodeoxycholic acid [UDCA] at time of analysis), from 422 patients with different hepatic and non-hepatic disorders, and from 50 healthy individuals were tested by ELISA for antibodies against full-length-SO (SO-fl) and its three major domains expressed in E...

BACKGROUND: Intrahepatic cholestasis of pregnancy (ICP), as a pregnancy-specific liver disorder, obtains increasing recognition due to a series of adverse outcomes. ICP is generally characterized by pruritus and jaundice, and closely related to abnormalities in the metabolism and disposition of bile acids composition. Because of its elusive pathogenesis, ICP has become an intractable issue to be diagnosed and managed for obstetricians. Analysis of metabolic profile could reveal the state of small-molecule metabolites systematically and provide comprehensively metabolic information for diseases...

BACKGROUND AND 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 due 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 Unites States (US) and other countries...

T Liwinski, C Schramm
Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease of unknown etiology. Characteristic features are multifocal strictures and dilatations of the bile ducts. In 60-80 % of cases the PSC is strongly associated with chronic inflammatory bowel disease, mostly in the form of pancolitis. The diagnosis is established based on detection of typical cholangiographic lesions of the bile ducts and exclusion of secondary causes of sclerosing cholangitis. There is no approved medical treatment, but in Germany ursodeoxycholic acid is frequently used...

The aim of this study was to investigate the anti-inflammatory effects by ursodeoxycholic acid (UDCA) in rats with a spinal cord injury (SCI). A moderate mechanical compression injury was imposed on adult Sprague-Dawley (SD) rats. The post-injury locomotor functions were assessed using the Basso, Beattie, and Bresnahan (BBB) locomotor scale and the tissue volume of the injured region was analyzed using hematoxylin and eosin staining. The pro-inflammatory factors were evaluated by immunofluorescence (IF) staining, a quantitative real-time polymerase chain reaction (qRT-PCR), and enzyme-linked immunosorbent assay (ELISA)...

The intestinal barrier is often disrupted in disease states, and intestinal barrier failure leads to sepsis. Ursodeoxycholic acid (UDCA) is a bile acid that may protect the intestinal barrier. We hypothesized that UDCA would protect the intestinal epithelium in injury models. To test this hypothesis, we utilized an in vitro wound healing assay and a mouse model of intestinal barrier injury. We found that UDCA stimulates intestinal epithelial cell migration in vitro, and this migration was blocked by inhibition of COX-2, EGFR, or ERK...

BACKGROUND: Bile acids (BAs) conduct crucial signals in human metabolism. Correlations between human plasma BA alterations and insulin secretion defects and type 2 diabetes (T2D) progression have been insufficiently studied. This study was performed to explore the trajectories of human plasma BA alterations and their association with the insulin secretion dynamics during a two-step hyperglycemic clamp. METHODS: Eleven healthy (NGT) and 33 drug-naïve T2D subjects (T2Ds) were enrolled to undertake a two-step hyperglycemic clamp...

BACKGROUND: Depression is prevalent in primary biliary cholangitis (PBC) patients. Our aims were to examine the effects of depression and antidepressants on hepatic outcomes of PBC patients. METHODS: We used the UK Health Improvement Network database to identify PBC patients between 1974 and 2007. Our primary outcome was one of three clinical events: decompensated cirrhosis, liver transplantation and death. We assessed depression and each class of antidepressant medication in adjusted multivariate Cox proportional hazards models to identify independent predictors of outcomes...
