Cholangitis sclerosing

Patients may manifest extraintestinal symptoms of IBD, such as arthritis, primary sclerosing cholangitis, erythema nodosum, and pyoderma gangrenosum, among others.

Alkaline phosphatase levels and GGT are elevated in plasma with obstructive disorders that disrupt the flow of bile from hepatocytes to the bile ducts or from the biliary tree to the intestines in condition such as primary biliary cirrhosis, sclerosing cholangitis, drug-induced cholestasis, gallstone disease, and autoimmune cholestatic liver disease. 

Approximately 11% of patients with ulcerative colitis have hepatobiliary complications including fatty liver, pericholangitis, chronic active hepatitis, cirrhosis, sclerosing cholangitis, cholangiocarcinoma, and gallstones. 

In bile-duct epithelial cells, the anti-apoptotic protein Mcl-l is strongly expressed in the pre-neoplastic bile-duct inflammatory disease, primary sclerosing cholangitis." This condition appears to involve intra-cellular accumulation of hydrophobic bile acids. 

The study authors pointed out the relatively short duration of this study may have limited the magnitude of any UDCA effect observed, particularly as the beneficial effect of UDCA on dysplasia incidence in one of the primary sclerosing cholangitis studies only became apparent after longer duration therapy. ...

Primary sclerosing cholangitis, congenital anomalies of the pancreaticobiliary tree, and parasitic infections are also associated with bile duct cancer. 

Sclerosing cholangitis administration of UDCA has not been followed by benefit in patients with primary sclerosing cholangitis. Progression of disease commonly leads to the consideration of hepatic transplantation.

Immunology. Blood tests can detect viruses and antibodies to viruses, for example hepatitis A/B virus, or auto-antibodies from autoimmune disorders of the liver, for example primary biliary cirrhosis (associated with anti-mitochondrial antibodies), autoimmune hepatitis (associated with smooth muscle antibodies) and primary sclerosing cholangitis (associated with antinuclear cytoplasmic antibodies).

Primary sclerosing cholangitis is characterised by inflammation, fibrosis and destruction of the intrahepatic and/or extrahepatic bile ducts. It results in a chronic cholestatic liver disease that may lead to liver cirrhosis. Cholangiocarcinoma occurs in approximately 10-30% of patients. PSC occurs more frequently in men between the ages of 20 and 40, with a male female ratio of 2 1. It is often associated with inflammatory bowel disease, particularly chronic ulcerative colitis. 

Sclerosing cholangitis in childhood is rare it may overlap with autoimmune liver disease and may be secondary, for example, to Langerhans cell histiocytosis. 

Approximately 3-10% of patients with inflammatory bowel disease have some degree of liver abnormality. The spectrum of liver dysfnnction associated with inflammatory bowel disease ranges from fatty changes to pericholangitis, sclerosing cholangitis, chronic active hepatitis and cirrhosis. Ulcerative colitis is more commonly associated with liver abnormality than Crohn s disease. 

Patients with cholestatic conditions such as gallstones, primary sclerosing cholangitis or Alagille s syndrome often suffer from pruritus that can be extremely debilitating. In such patients it would seem sensible to avoid medication that could exacerbate this symptom. Administration of opiates via the intrathecal and epidural routes lead to a high incidence of pruritus (up to 80% with epidural morphine) [2].
