Primary Sclerosing Cholangitis in Children
Recruiting
Primary sclerosing cholangitis (PSC) is a rare liver disease that damages the liver's bile ducts. Bile ducts are tiny tubes that carry bile from the liver to the small intestine.

In people with PSC, the bile backs up into the liver and will damage it, causing scarring of the liver. The purposes of this study are to: * Collect medical and other data to learn more about PSC, how it progresses, a... Read More
