Primary Biliary Cirrhosis News and Research

RSS

Primary biliary cirrhosis is a chronic disease that causes the bile ducts in the liver to become inflamed and damaged and, ultimately, disappear. Bile is a liquid produced in the liver that travels through the bile ducts to the gallbladder and then the small intestine, where it helps digest fats and fat-soluble vitamins A, D, E, and K. When the bile ducts become damaged from chronic inflammation, bile builds up in the liver, injuring liver tissue.

Paper discussing the mechanism of the selective TGR5 agonist INT-777 published in Cell Metabolism

Bile acids are known to be key regulators of lipid, glucose and overall energy metabolism. Bile acid activation of the G protein-coupled receptor TGR5 has been shown to induce energy expenditure in muscle and brown fat, thereby conferring resistance to weight gain.

Study unveils detrimental effects of high-dose ursodeoxycholic acid on patients with PSC

Primary sclerosing cholangitis (PSC) is an uncommon chronic liver disease characterized by progressive inflammation and destruction of the bile ducts. The disease progresses slowly, usually leading to biliary cirrhosis, portal hypertension and liver failure over a 10-15 year period. PSC is a common cause of adult cholestatic liver diseases and a primary source behind many of the liver transplantations in U.S. adults. At least 70% of PSC cases are associated with chronic inflammatory bowel disease (IBD), usually ulcerative colitis. Currently, there is no cure for PSC and prospective treatments remain ineffective.

Research identifies 3D structure of key nuclear pore building block

The genome of complex organisms is stashed away inside each cell's nucleus, a little like a sovereign shielded from the threatening world outside.

Discovery of genetic cause for primary biliary cirrhosis

Researchers have discovered a novel molecular path that predisposes patients to develop primary biliary cirrhosis, a disease that mainly affects women and slowly destroys their livers. Primary biliary cirrhosis has no known cause.

Biochemical markers for non-invasive assessment of primary biliary cirrhosis

Needle liver biopsy has been used as the "gold standard" for the assessment of liver fibrosis and disease stage of PBC.

Cause of effectiveness discovered for a cirrhosis treatment useful in 40 percent of patients

Scientists of the Center for Applied Medical Research (CIMA) of the University of Navarra have discovered the molecular mechanism responsible for the effectiveness of an existing treatment for primary biliary cirrhosis, which combines two substances in order to produce an effect that does not result from either substance separately.

Over 2 decades experiences shows that ultrasound-guided liver biopsy is the procedure of choice

Liver biopsy is a widely used tool in the investigation of liver diseases. It is invasive and has a mortality risk ranging between 0.01% and 0.17%. A liver biopsy should therefore only be performed in patients who would potentially benefit from it.

Over 60's do well after liver transplantation

Patients who undergo liver transplantation at age 60 or above have 1-year and 5-year survival rates similar to those of younger patients and they experience fewer episodes of rejection.

First-degree relatives of patients with primary biliary cirrhosis more likely to have biomarkers of the disease

Armed with this new information, physicians could screen and assess first-degree relatives of PBC patients with a simple blood test, enabling them to diagnose and treat more patients before the disease causes irreversible liver damage. These findings were published in this month's issue of Hepatology.

Exposure to toxins from hazardous waste sites may be a significant risk factor for developing primary biliary cirrhosis

Published in the March 2006 issue of Hepatology, researchers found significant clusters of the disease near Superfund toxic waste sites (SFS) and that the majority of patients in New York City who need liver transplants because of PBC, reside near SFS.

New pathways linking liver disease to changes in the central nervous system

Liver disease is often associated with "sickness behaviors," such as malaise, listlessness, anorexia, difficulty concentrating, and fatigue. In cholestatic liver diseases (where bile production is impaired) such as primary biliary cirrhosis, fatigue occurs in up to 86 percent of patients.

Largest study to date on risk factors associated with primary biliary cirrhosis

A case-control study of more than 2000 people has identified a number of factors that may induce primary biliary cirrhosis (PBC) in genetically susceptible individuals. These include a history of urinary tract infections, hormone replacement therapy, tobacco use, and nail polish use.

Patients with primary biliary cirrhosis who are treated with methotrexate have an increased risk of death

In five randomized controlled trials involving 457 people, the authors report that for patients treated with methotrexate, as a single therapy or in combination with other drug treatment, pooled data showed a tendency toward an increased risk of death or liver transplantation. The brand names for methotrexate are Rheumatrex and Trexall.
