The hepatopulmonary syndrome results from the formation of microscopic intrapulmonary arteriovenous dilatations in patients with both chronic, and far less commonly acute liver failure. The mechanism is unknown but is thought to be due to increased liver production or decreased liver clearance of vasodilators, possibly involving nitric oxide. [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.
Drug-induced liver injury (DILI) is a cause of acute and chronic liver disease caused specifically by medications and the most common reason for a drug to be withdrawn from the market after approval. The liver plays a central role in transforming and clearing chemicals and is susceptible to the toxicity from these agents.
This causes many of the sequelae of chronic liver disease including esophageal varices (with associated variceal bleeding), ascites and splenomegaly. The chronic inflammation seen in alcoholic hepatitis also leads to impaired hepatocyte differentiation, impairments in hepatocyte regeneration and hepatocyte de-differentiation into cholangiocyte ...
The treatment of chronic liver disease depends on the cause. Specific conditions may be treated with medications including corticosteroids, interferon, antivirals, bile acids or other drugs. Supportive therapy for complications of cirrhosis include diuretics, albumin, vitamin K, blood products, antibiotics and nutritional therapy.
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is an acute condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
Liver diseases, including conditions such as non-alcoholic fatty liver disease (NAFLD), alcohol-related liver disease (ALD), and viral hepatitis, are significant public health concerns worldwide. In the United States, NAFLD is the most common chronic liver condition, affecting approximately 24% of the population, with the prevalence rising due ...
Chronic liver failure usually occurs in the context of cirrhosis, itself potentially the result of many possible causes, such as excessive alcohol intake, hepatitis B or C, autoimmune, hereditary and metabolic causes (such as iron or copper overload, steatohepatitis or non-alcoholic fatty liver disease).
