Overview
Primary sclerosing cholangitis is a progressive disease that often results in death from complications of liver failure, liver transplantation or associated carcinomas. Even with liver transplantation, there is a substantial risk of recurrence of the disease. Complications of primary sclerosing cholangitis include osteoporosis, cholangiocarcinoma and liver failure.
Natural History
Primary sclerosing cholangitis is a progressive and often fatal disease. Death in patients with primary sclerosing cholangitis often results from complications of liver failure or associated cancers, such as cholangiocarcinoma, hepatocellular carcinoma, and colorectal carcinoma in patients with associated IBD.[1] The median survival from diagnosis to death in patients with primary sclerosing cholangitis ranges between 12-18 years.[2]
Complications
Some of the complications of primary sclerosing cholangitis include:[3]
- Osteoporosis: Patients with primary sclerosing cholangitis lose 1% of their bone mass every year.[4]
- Liver cirrhosis and end-stage liver disease (ESLD).
- Cholangiocarcinoma: the risk of cholangiocarcinoma in patients with primary sclerosing cholangitis is 400 times higher than the risk in the general population.[5]
Prognosis
Primary sclerosing cholangitis is a slowly progressive disease that may ultimately lead to liver failure.[3] Approximately 40% of patients require liver transplantation.[6] Even then, the 1 year survival rate after liver transplantation is 85% and 72% after 5 years. 25% of patients have recurrence of the disease after transplantation.[7]
The following factors are associated with a poorer prognosis in patients with primary sclerosing cholangitis:[3]
- The classic disease is associated with a poorer prognosis than small bile duct disease.[8][5]
- Patients with primary sclerosing cholangitis and an increased serum level of IgG4 have a worse prognosis than patients with primary sclerosing cholangitis and a normal serum level of IgG4.[9]
- After one to two years of diagnosis, patients with serum alkaline phosphatase level of ≥1.5 times the upper limit of the normal range have a worse outcome than patients who have serum alkaline phosphatase levels of less than 1.5 times the upper limit of the normal range.[10][11][12]
- High grade intrahepatic strictures on cholangiography.[2]
The Mayo Score for PSC uses an equation to predict the survival in patients with primary sclerosing cholangitis. The variables in this equation include age, AST levels, total bilirubin levels, serum albumin, as well as variceal bleeding.[13]
