For Patients Caregiver Tips and Advice For Medical Professionals

Primary Sclerosing Cholangitis

Primary sclerosing cholangitis (PSC) is a chronic, or long-term, disease that slowly damages the bile ducts. Bile is a digestive liquid that is made in the liver. It travels through the bile ducts to the gallbladder and the small intestine, where it helps digest fats and fatty vitamins.

In patients with PSC, the bile ducts become blocked due to inflammation and scarring or fibrosis. This causes bile to accumulate in the liver, where it gradually damages liver cells and causes cirrhosis, or fibrosis of the liver. As cirrhosis progresses and the amount of scar tissue in the liver increases, the liver slowly loses its ability to function. The scar tissue may block drainage of the bile ducts leading to infection of the bile.

PSC advances very slowly. Many patients may have the disease for years before symptoms develop. Symptoms may remain at a stable level, they may come and go, or they may progress gradually. Liver failure may occur 10-15 years after diagnosis, but this may take even longer for some PSC patients. Many people with PSC will ultimately need a liver transplant, typically about 10 years after being diagnosed with the disease. PSC may also lead to bile duct cancer. Endoscopy and MRI tests may be done to monitor the disease.

Many people with PSC do not get symptoms, especially in the early stages of the disease. When symptoms do occur the most common are fatigue, pruritus, or itching of the skin, and jaundice, a yellowing of the skin and eyes. These symptoms may come and go, but they may worsen over time. As the disease continues, the bile ducts may become infected, which can lead to episodes of fever, chills and abdominal pain.

The cause of this disease is not known. About 70 percent of patients are men. It may be related to bacterial or viral infections, as well as problems in the immune system. Genetic factors may also play a role. PSC is considered an uncommon disease, but recent studies suggest that it may be more common than previously thought.

Because many PSC patients have no symptoms, the disease is often discovered through abnormal results on routine liver blood tests. Formal diagnosis is usually made by cholangiography, an X-ray test involving injection of dye into the bile ducts, or by a MRI.

There is no cure or specific treatment for PSC. The itching associated with the disease can be relieved with medication, and antibiotics are used to treat bile duct infections when they occur. Most people with PSC must take vitamin supplements. In some cases, bile duct surgery or endoscopy may be useful to temporarily improve bile flow.

Over time, many PSC patients will continue to suffer a gradual loss of liver function. If liver failure becomes severe, a liver transplant may be necessary. The outcome for patients with PSC who have undergone transplantation is excellent. The survival rate for two or more years is about 80 percent, with a good quality of life after recovery

PSC is slightly more common in men than women. It usually affects people between the ages of 30 and 60. As many as 75 percent of patients with PSC also have inflammatory bowel diseases, usually ulcerative colitis.

PSC has been known for 100 years, but now doctors are able to diagnose it very early. This means that treatment can begin before the liver is severely damaged. Scientists are continuing to study the disease to find the cause and understand its development.

In addition, drug therapy trials, involving a large number of patients around the world, are exploring the potential use of several additional medications to lessen the symptoms and control liver damage.

  • How severe is the liver damage?
  • What treatment do you recommend? Will this slow down the progression of the disease?
  • Will any medication be prescribed? What are the side effects?
  • Should I change my diet?
  • Are there any supplements you would suggest that I take?
  • What can be done to relieve my symptoms?
  • Does screening for bile duct cancer need to be done now?
