Study Notes
- The liver has crucial functions such as synthesizing and metabolizing various substances, including bilirubin and bile acids.
- Major primary liver diseases include viral hepatitis, alcohol liver disease, nonalcoholic fatty liver disease, and hepatocellular carcinoma.
- In the West, alcohol and hepatitis C virus are significant causes of liver disease, while hepatitis B virus is more prevalent elsewhere.
- Jaundice is characterized by yellowing of the skin and sclerae, often caused by elevated serum bilirubin levels.
- Haemolytic jaundice results from increased red blood cell breakdown, while cholestatic jaundice is due to bile flow obstruction.
- Hepatitis C virus (HCV) primarily spreads through blood or blood products and can lead to chronic hepatitis, cirrhosis, and hepatocellular carcinoma.
- Hepatitis A spreads through the fecal-oral route, causing acute viral hepatitis with relatively short incubation and self-limiting nature.
- Hepatitis B is a DNA virus that spreads through parenteral routes and close personal contact, with a long incubation period and potential for chronic carriers.
