Primary biliary cirrhosisPBC
Primary biliary cirrhosis is irritation and swelling (inflammation) of the bile ducts of the liver. This blocks the flow of bile, which damages the liver cells and leads to scarring called cirrhosis.
The cause of inflamed bile ducts in the liver is not known. However, primary biliary cirrhosis is an autoimmune disorder. That means your body's immune system mistakenly attacks healthy tissue.
The disease more commonly affects middle-aged women.
More than half of patients have no symptoms at the time of diagnosis. Symptoms most often come on slowly and may include:
- Abdominal pain
- Enlarged liver
- Fatty deposits under the skin
- Fatty stools
- Soft yellow spots on the eyelid
Exams and Tests
The doctor or nurse will do a physical exam.
The following tests can check to see if your liver is working properly:
- Albumin blood test
- Liver function tests (serum alkaline phosphatase is most important)
- Prothrombin time (PT)
- Cholesterol and lipoprotein blood tests
Other tests that can help diagnose this disease are:
- Elevated immunoglobulin M level in the blood
- Liver biopsy
- Anti-mitochondrial antibodies (results are positive in about 95% of cases)
The goal of treatment is to ease symptoms and prevent complications.
Cholestyramine (or colestipol) may reduce the itching. Ursodeoxycholic acid may improve removal of bile from the bloodstream. This may improve survival in some patients.
Vitamin replacement therapy restores vitamins A, K, E and D, which are lost in fatty stools. A calcium supplement or other bone medicines may be added to prevent or treat weak or soft bones (osteoporosis, and rarely osteomalacia).
Liver transplant may be successful if it is done before liver failure occurs.
The outcome can vary. If the condition is not treated, most patients will die without a liver transplant. About a quarter of patients who have had the disease for 10 years will have liver failure. Doctors can now use a statistical model to predict the best time to do the transplant. Other diseases such as hypothyroidism and anemia can also develop.
Progressive cirrhosis can lead to liver failure. Complications can include:
- Damage to the brain (encephalopathy)
- Fluid and electrolyte imbalance
- Kidney failure
- Soft or weak bones (osteomalacia or osteoporosis)
