Study Notes

Preventable Causes and Consequences of Liver Disease

  • Three main preventable causes of liver disease: alcohol misuse, obesity, and viral hepatitis.
  • Uncontrolled accumulation of acetyl-CoA in the liver disrupts normal metabolic processes, leading to fatty liver and potential liver damage.

Liver Disease Statistics and Impact

  • Liver disease is the fifth leading cause of death in England and Wales.
  • Approximately 500,000 individuals in the UK are affected by liver disease.

Immune Function and Liver Health

  • The liver maintains immune tolerance, crucial for preventing overactive immune responses which can lead to tissue damage.
  • Uncontrolled T-cell activation in the liver can trigger autoimmune reactions, damaging liver cells.
  • The liver primarily processes foreign antigens through the action of specialized cells that help discern between harmful and harmless substances.

Jaundice and Its Connection to Liver Disease

  • Jaundice is the yellowing of the skin and eyes, often a symptom of liver dysfunction.
  • Causes of jaundice in the context of liver disease include liver cell damage, bile duct obstruction, and hemolysis (increased breakdown of red blood cells).

Preventative Measures and Early Detection

  • Preventative measures for liver health include maintaining a healthy weight, reducing alcohol intake, and vaccination against hepatitis.
  • Early detection methods include regular liver function tests and monitoring for symptoms related to liver disease.

Non-Alcoholic Fatty Liver Disease (NAFLD)

  • NAFLD is linked to insulin resistance, where the liver excessively stores fat, potentially leading to inflammation and cirrhosis.
  • The liver regulates glucose and insulin levels, playing a vital role in metabolic homeostasis.
  • Monitoring insulin resistance in NAFLD patients is essential to prevent progression to more severe liver disease.

Functions of the Liver

  • The liver performs various metabolic functions, including detoxification, protein synthesis, and bile production.
  • Hepatocytes are specialized liver cells that metabolize bilirubin, a byproduct of red blood cell breakdown.
  • Bilirubin metabolism involves conjugation and excretion into bile, which is stored in the gallbladder.

Detoxification Phases and Liver Health Strategies

  • Detoxification occurs in two phases:
    • Phase 1 involves chemical modification (oxidation, reduction, hydrolysis).
    • Phase 2 involves conjugation reactions that make substances more water-soluble for excretion.
  • Understanding liver functions and immune tolerance can inform therapies for autoimmune diseases and liver health strategies.

Liver Cells and Visualization Techniques

  • Different liver cells include hepatocytes (main functional cells), Kupffer cells (macrophages), and liver sinusoidal endothelial cells (specialized endothelial cells).
  • Liver sinusoidal endothelial cells can be visualized using microscopy techniques for research on liver health and disease.

Obesity and Liver Disease

  • The increasing prevalence of obesity underscores the need for targeted strategies to mitigate liver disease risk, particularly in adults.
