Primary Sclerosing Cholangitis (PSC)

== Background ==

Autoimmune Dz typically seen in young men

Progressive inflammation and fibrosis of intra/extra hepatic bile ducts

Most (80%) cases are associated with inflammatory bowel dz, typically ulcerative colitis, 10% of pts with ulcerative colitis have PSC

Increased risk of colon CA in pts with Ulcerative colitis and PSC (more than UC alone) Increased risk of cholangiocarcinoma

Prevalence is 1 to 6 per 100,000 in the U.S

== Clinical Features ==

Generally asymptomatic but can present with fatigue, abd pain, jaundice, cholangitis, puritis, weight loss, or fever

Mean age at presentation: 30-40 

== Diagnosis ==

Cholangiography

Dx made by ERCP or MRCP, which demonstrates strictures or beading of the intrahepatic or extrahepatic bile ducts

Liver biopsy typically shows pericholangitis and periductual fibrosis but is often not diagnostic in early dz

 

== Work-Up ==

Alkaline phosphatase is usually elevated with mild elevations in aminotransferases

Bilirubin is typically normal, except when common hepatic duct or common bile duct is involved in late stages of dz

Perinuclear antineutrophil cytoplasmic antibody (pANCA) positive in 2/3rds of cases

== DDx ==

== Treatment ==

High dose Ursodeoxycholic acid (UDCA), 25-30mg/kg/day, may improve liver chemistries but does not slow dz progression and may actually hasten development of portal HTN

Periodic dilation of strictures via ERCP or percutaneous route

Liver Transplant should be offered to those with advanced liver dz or repeated bouts of cholangitis (Dz can recur after transplantation)

== Disposition ==

 Annual Screening for colon cancer in pts with concomitant UC
