Digestive system

Bile pathway

Primary biliary cirrhosis

Definition:

Primary biliary cirrhosis is irritation and swelling (inflammation) of the bile ducts of the liver, which blocks the flow of bile . This obstruction damages liver cells.

Alternative Names: PBC

Causes, incidence, and risk factors:

The cause of inflamed bile ducts in the liver is not known. The disease more commonly affects middle-aged women.

Long-term bile obstruction is believed to lead to liver cirrhosis . The disease may be associated with autoimmune disorders such as:

Arthritis
CREST syndrome
Hypothyroidism
Raynaud's phenomenon

Symptoms:

Symptoms usually come on gradually and may include:

Abdominal pain
Enlarged liver
Fatigue
Fatty deposits under the skin
Fatty stools
Itching
Jaundice
Soft yellow spots on the eyelid

Signs and tests:

Tests for the disease:

Elevated immunoglobulin M level in the blood
Liver biopsy
Mitochondrial antibodies (positive in about 95% of cases)

Tests for liver dysfunction :

Liver function tests
Serum cholesterol and lipoproteins

Treatment:

Therapy aims to relieve symptoms and prevent complications.

Cholestyramine (or colestipol) may reduce the itching. Ursodeoxycholic acid may improve removal of bile from the bloodstream.

Vitamin replacement therapy restores vitamins A, K, and D, which are lost in fatty stools. A calcium supplement can help prevent soft, weakened bones (osteomalacia ).

Liver transplant before liver failure occurs may be successful.

Support Groups:

Expectations (prognosis):

The outcome can vary. If the condition is not treated, most patients will need a liver transplant after about 7 years. Doctors can now use statistics to predict the best time to do the transplant.

Complications:

Progressive cirrhosis can lead to liver failure. Complications can include:

Bleeding
Damage to the brain (encephalopathy )
Fluid and electrolyte imbalance
Kidney failure
Malabsorption
Malnutrition
Soft bones (osteodystrophy)

Calling your health care provider:

Call your health care provider if you have:

Abdominal swelling
Blood in the stools
Confusion
Jaundice
Itching of the skin that does not go away and is not related to other causes
Vomiting blood
