Hepatitis and Liver Cancer

Hepatitis and Liver Cancer: Understanding the Link

Hepatitis refers to inflammation of the liver, a vital organ responsible for processing nutrients, filtering blood, and fighting infections.

Types of Hepatitis

There are five main types of viral hepatitis;

Hepatitis A, B, C, D, and E. Each type is caused by a different virus and has various modes of transmission and impacts on liver health.

  • Hepatitis A (HAV): This type spreads through the ingestion of contaminated food or water. Symptoms can be resolved without treatment.
  • Hepatitis B (HBV): This type is transmitted through contact with infectious blood, semen, or other body fluids. Hepatitis B can be acute or chronic and may lead to severe liver damage over time if left untreated.
  • Hepatitis C (HCV): This is the most common type of infection that spreads through blood-to-blood contact. This can be asymptomatic in the early stages but can lead to chronic liver disease if untreated.
  • Hepatitis D (HDV):  This type can occur only in individuals infected with Hepatitis B. It can accelerate liver damage and is transmitted through contact with infected blood.
  • Hepatitis E (HEV): This is usually transmitted through consumption of contaminated water. Similar to Hepatitis A, it causes acute illness and does not typically result in chronic infection.

What Causes Hepatitis?

Hepatitis can be caused by viruses, alcohol and other toxins, autoimmune conditions, and certain medications or drugs. Viral hepatitis (especially Hepatitis A, B, and C) is the most common form worldwide.

How does it Spread?

  • Hepatitis A: Contaminated food or water
  • Hepatitis B: Contact with infectious body fluids
  • Hepatitis C: Blood-to-blood contact, often through sharing needles or other drug paraphernalia

Who is at Risk for Hepatitis?

  • Hepatitis A: Travelers to areas with poor sanitation.
  • Hepatitis B: Infants born to infected mothers, healthcare workers, and individuals with multiple sexual partners.
  • Hepatitis C: People who inject drugs, recipients of blood transfusions before 1992, and healthcare workers exposed to blood.

Symptoms of Hepatitis

  • Jaundice
  • Fatigue
  • Abdominal pain
  • Nausea and vomiting
  • Loss of appetite

How is Hepatitis Diagnosed?

  • Blood tests to detect viral antigens, antibodies, or liver enzymes.
  • Imaging tests like ultrasound used to assess liver damage.

Treatments for Hepatitis

  • Hepatitis A: Generally resolves on its own, with supportive care.
  • Hepatitis B: Antiviral medications can manage chronic infections.
  • Hepatitis C: Antiviral therapy can cure most cases of chronic hepatitis C.
  • Hepatitis D and E: Supportive care to manage symptoms, as specific antiviral treatments are limited.

Prevention

  • Vaccination for Hepatitis A and B
  • Safe hygiene practices
  • Safe sex practices
  • Avoiding sharing needles
