prevention
The cause of PBC is unknown but research suggests it may be a result of problems with the immune system. Genetic factors may also play a role in developing this disease.
diagnosis
Since many patients with PBC do not experience any symptoms, diagnosis is often found through routine blood tests. For patients that are experiencing symptoms, a blood test is done to check the levels of antimitochondrial antibodies in the blood. If this test comes back positive, it is likely that the patient has primary biliary cholangitis. A liver biopsy (small sample of liver tissue) may also be requested to confirm the diagnosis and rule our other diseases. A liver biopsy, where a small sample of liver tissue is removed with a small needle can help confirm the diagnosis.
treatment
PBC is a chronic long-lasting condition that can be controlled in most patients, but not cured. The prognosis of PBC has improved over the last two decades due to earlier diagnosis and improved treatment. Early access to treatment can significantly delay progression of the disease.
- A medication called ursodeoxycholic acid (also called UDCA, URSO) mimics a naturally occurring bile acid. This medication can improve liver function and delay the development of fibrosis (scar tissue) in the liver, which in turn can delay or eliminate the potential for PBC to progress towards liver failure and/or liver transplantation.
- Vitamins A, D, E and K can be prescribed, usually when severe cholestasis and jaundice is present.
- Various medications may be prescribed by your doctor to help reduce itching. Some examples of these medications include cholestyramine, antihistamines or other medications.
- Obeticholic acid (OCA), which is a man-made bile acid that acts to reduce liver inflammation and cholestasis, is available in Canada.
Liver transplantation may be recommended for eligible candidates if other treatments are no longer helpful, and liver damage and scarring has progressed to the point that the liver is no longer able to work properly. Liver transplantation works well for people with PBC, although it is possible to develop PBC in your new liver.
