Learn About Primary Biliary Cholangitis

What is the definition of Primary Biliary Cholangitis?

The bile ducts are tubes that move bile from the liver to the small intestine. Bile is a substance that helps with digestion. All of the bile ducts together are called the biliary tract.

When the bile ducts become swollen or inflamed, this blocks the flow of bile. These changes can lead to scarring of the liver called cirrhosis. This is called biliary cirrhosis. Advanced cirrhosis can lead to liver failure.

What are the alternative names for Primary Biliary Cholangitis?

Primary biliary cirrhosis; PBC

What are the causes of Primary Biliary Cholangitis?

The cause of inflamed bile ducts in the liver is not known. However, primary biliary cholangitis is an autoimmune disorder. That means your body's immune system mistakenly attacks healthy tissue. The disease may be linked to autoimmune disorders such as:

  • Celiac disease
  • Raynaud phenomenon
  • Sicca syndrome (dry eyes or mouth)
  • Thyroid disease

The disease most often affects middle-aged women.

What are the symptoms of Primary Biliary Cholangitis?

More than one half of people have no symptoms at the time of diagnosis. Symptoms most often begin slowly. Early symptoms may include:

  • Nausea and belly pain
  • Fatigue and loss of energy
  • Fatty deposits under the skin
  • Fatty stools
  • Itching
  • Poor appetite and weight loss

As liver function worsens, symptoms may include:

  • Fluid buildup in the legs (edema) and in the abdomen (ascites)
  • Yellow color in the skin, mucous membranes, or eyes (jaundice)
  • Redness on the palms of the hands
  • In men, impotence, shrinking of the testicles, and breast swelling
  • Easy bruising and abnormal bleeding, most often from swollen veins in the digestive tract
  • Confusion or problems thinking
  • Pale or clay-colored stools

What are the current treatments for Primary Biliary Cholangitis?

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 people. A newer drug called obeticholic acid (Ocaliva) is also available.

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.

Long-term monitoring and treatment of liver failure is needed.

Liver transplant may be successful if it is done before liver failure occurs.

What is the outlook (prognosis) for Primary Biliary Cholangitis?

The outcome can vary. If the condition is not treated, most people will die without a liver transplant. About one quarter of people 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.

What are the possible complications of Primary Biliary Cholangitis?

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 or weak bones (osteomalacia or osteoporosis)
  • Ascites (fluid buildup in the abdominal cavity)
  • Increased risk of liver cancer
When should I contact a medical professional for Primary Biliary Cholangitis?

Contact your 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

The Role of the Vitamin D Receptor Gene Polymorphisms in Hepatocarcinogenesis in Cirrhotic Patients Infected With Chronic Hepatitis C Virus

Summary: Previous data have suggested that vitamin D levels may influence cancer development. In particular, several single nucleotide polymorphisms have been described in the Vitamin D receptor( VDR gene), and some polymorphisms are associated with tumor occurrence. For instance, VDR polymorphisms have been related to cancers of the breast, prostate, skin, colon-rectum, bladder and kidney, although with c...
