Primary sclerosing cholangitis is one of the major known risk factors for cholangiocarcinoma, [40] a cancer of the biliary tree, for which the lifetime risk among patients with PSC is 10-15%. [3] This represents a 400-fold greater risk of developing cholangiocarcinoma compared to the general population. [ 1 ]
Cholestatic pruritus is the sensation of itch due to nearly any liver disease, but the most commonly associated entities are primary biliary cholangitis, primary sclerosing cholangitis, obstructive choledocholithiasis, carcinoma of the bile duct, cholestasis (also see drug-induced pruritus), and chronic hepatitis C viral infection and other forms of viral hepatitis.
Ulcerative colitis (UC) has a significant association with primary sclerosing cholangitis (PSC), a progressive inflammatory disorder of small and large bile ducts. Up to 70-90% of people with primary sclerosing cholangitis have ulcerative colitis. [34] As many as 5% of people with UC may progress to develop primary sclerosing cholangitis.
Bile duct abnormalities (cholangitis, ductal injury, ductular reaction) can be seen and should prompt evaluation for primary biliary cholangitis or sarcoidosis if granulomas are observed. Plasma cell infiltrate, rosettes of hepatocytes, and multinucleated giant cells. Varying degrees of fibrosis (except in the mildest form of autoimmune hepatitis).
Chronic cholestasis is a feature in primary sclerosing cholangitis (PSC). PSC is a rare and progressive cholestatic liver disease characterized by narrowing, fibrosis, and inflammation of intrahepatic or extrahepatic bile ducts, leading to reduced bile flow or formation (i.e., cholestasis).
Inflammation of the biliary duct is called cholangitis, which may be associated with autoimmune disease, such as primary sclerosing cholangitis, or a result of bacterial infection, such as ascending cholangitis. [5]: 977–978, 963–968 Disease of the biliary tree may cause pain in the upper right abdomen, particularly when pressed.
The incidence of cholangiocarcinoma increases with age, and the disease is slightly more common in men than in women (possibly due to the higher rate of primary sclerosing cholangitis, a major risk factor, in men). [47] The prevalence of cholangiocarcinoma in people with primary sclerosing cholangitis may be as high as 30%, based on autopsy ...
These diseases include primary biliary cirrhosis, primary sclerosing cholangitis, AIDS cholangiopathy, disappearing bile duct syndromes, Alagille's syndrome, cystic fibrosis, and biliary atresia. Often either the best or the only curative treatment option for cholangiopathies is liver transplantation , and as a group, cholangiopathies account ...
