Primary biliary cirrhosis (PBC) is a chronic liver disease. It generally strikes women between the ages of 40 and 60, but it has been diagnosed outside of this age range as well as in men. While PBC is not considered to be hereditary, the disease can be seen occasionally in siblings.
Other symptoms, not directly related to PBC, are also often reported by patients:
As the liver damage progresses, other symptoms may appear, which affect the rest of the body. These symptoms include:
Diagnosis is made with special blood tests including liver bichemistry. One such test detects the presence of antimitochondrial antibodies (AMA) in blood. Also, a liver biopsy may be performed. This is a procedure in which a small needle is inserted into the liver to take a sample of the tissue for analysis.
The prognosis of PBC varies greatly from one patient to another. Many lead active lives with few symptoms for 10 to 20 years. In some patients, however, the condition progresses more rapidly and liver deterioration may occur in just a few years.
There is currently no known specific treatment for PBC. Vitamins A, D and K can be prescribed, usually when jaundice is present; cholestyramine and antihistamines can successfully relieve itching. Ursodeoxycholic acid, a bile salt, has been shown to improve liver function and delay the development of fibrosis (scar tissue) and the need for liver transplantation. When ursodeoxycholic acid is given to individuals with early disease then survival becomes the same as that of individuals of the same age without PBC.
Complications of liver deterioration can often be controlled. As an example, a salt-restricted diet and medication (usually water pills) can be prescribed following accumulation of fluid.
Liver transplantation is now a common treatment option for people with advanced PBC.
What precautions should be taken?
Alcohol may increase damage to the liver and should not be consumed regularly by anyone with any liver disease. Patients should eat a healthy and well balanced diet.
There is a healthy way to live with a chronic disease and patients with PBC should be encouraged to maintain an active lifestyle under the supervision of their doctor.
It is important for PBC patients to realize that support is available that may help them to improve their quality of life.
