[Cholestatic liver diseases].

Abstract

Cholestatic liver disease is primarily caused by impaired bile production on the level of hepatocytes and cholangiocytes. Clinically cholestasis can be divided into intrahepatic and extrahepatic forms based on the presence or absence of dilated bile ducts (sonography). Intrahepatic cholestasis is most frequently caused by end stage liver cirrhosis followed by primary cholangiopathies and canalicular transport defects in hepatocytes. The causes of the most important cholangiopathies, such as Primary Biliary Cirrhosis (PBC) and Primary Sclerosing Cholangitis (PSC) are so far not known. Therefore, drug therapy of cholestatic liver disease focuses on the improvement of symptoms such as fatigue, pruritus, abdominal discomfort, jaundice, xanthoma, hypercholesterolemia, portal hypertension, blood count abnormalities, osteoporosis/osteomalacia, and the prevention of complications such as bile-duct strictures in PSC and development of cholangiocarcinoma. The first choice drug in the treatment of cholestatic liver disease of various causes is urosodeoxycholic acid (UDCA), that has been shown to decrease bile acid toxicity in general and prolong the transplant free survival of patients with PBC. If cholestasis persists cirrhosis of the liver is the major complication and liver transplantation may be the definitive treatment in advanced cases of cholestatic liver disease.
