Hepatitis D (Delta Virus): Causes, Symptoms, Diagnosis, and Treatment

Hepatitis D, often termed Delta Hepatitis, is an illness in which a specific virus (HDV) attacks and damages the liver. However, this virus can’t survive on its own; it needs the Hepatitis B virus (HBV) to be present. So, if someone doesn’t have Hepatitis B, they can’t get Hepatitis D.

This makes Hepatitis D a “co-infection” or a “superinfection.”

• A co-infection is when a person is infected with both viruses at the same time.
• A superinfection happens when someone who already has Hepatitis B later gets infected with Hepatitis D.

Hepatitis D can make liver disease more severe. It can also speed up liver damage compared to having just Hepatitis B alone. That’s why understanding and managing this condition is important.

Symptoms

Hepatitis D, like other types of hepatitis, affects the liver. Therefore, the symptoms are likely to affect liver functions and general health. Some people might not show any symptoms, especially in the early stages. However, when symptoms do develop, they may include:

• Feeling unusually weak, drained or fatigued.
• Yellowing of the skin and eyes (called jaundice) is a classic sign of liver trouble.
• Urine that appears much darker than usual.
• Pale or grey-colored stools, which lack the usual brown colour.
• Pain in the upper right side of the abdomen, where the liver is located.
• General loss of appetite, including not feeling like eating or feeling full quickly.
• Nausea and vomiting
• Joint pain or muscle aches, some people feel general body discomfort.

If the infection becomes chronic (long-term), it can slowly damage the liver over the years, which might lead to serious conditions like liver cirrhosis or even liver failure if not monitored and managed properly.

Diagnosis

Doctors usually test for HDV (Hepatitis D) in people who have been diagnosed with HBV (Hepatitis B), as it cannot infect people who are not already infected with it, especially if their condition is worsening or not improving as expected.

The diagnosis usually involves:

1. Medical History & Symptoms – The doctor will ask about symptoms, medical history, and whether the person has Hepatitis B or may have been exposed to the virus by coming in contact with an infected person. Hepatitis B is contagious and can infect people through blood, unprotected sex, or other bodily fluids that come in contact with an uninfected person.
2. Blood Tests – These are the main tools used to detect Hepatitis D. Blood tests can check for:
   • Antibodies to the Hepatitis D virus (which show up when the body has been exposed to the virus)
   • Genetic material (RNA) from the virus, which shows active infection
3. Liver Function Tests – These tests look at how well the liver is working and can show if there’s inflammation or damage.
4. Imaging or Liver Biopsy – In some cases, doctors might recommend imaging tests like an ultrasound or even a liver biopsy (a small tissue sample taken from the liver) to see how much damage has been done.

The diagnosis process helps doctors figure out how active the infection is and how much it may be affecting the liver.

Treatment

Hepatitis D is more aggressive than Hepatitis B, therefore making it more challenging to treat and manage. While there isn’t a one-size-fits-all treatment, the main goals of care are:

• Slowing down liver damage by trying to control the infection and reduce liver inflammation.
• Monitoring liver health over time with regular follow-up appointments and tests help keep track of liver function and catch any signs of worsening.
• Supporting overall health. Lifestyle changes can make a big difference. These may include:
  • Avoiding alcohol, since it can worsen liver damage
  • Eating a balanced, healthy diet to support the liver
  • Staying physically active helps with overall well-being
  • Avoiding unnecessary medications or toxins that might stress the liver

In some cases, doctors might recommend specific antiviral therapies, especially in severe or chronic cases, but this would depend on the individual and their overall health.

Conclusion

Hepatitis D is a type of hepatitis that doesn’t stand alone. It’s like an extra layer added to an already existing infection, making things a bit more complicated for the liver.

Hepatitis, although a lesser-known disease, is just as serious as other infections that affect the liver. Since it cannot occur without the existence of Hepatitis B, understanding the issues of one will help in understanding the other. If you or someone you know has Hepatitis B, it’s worth having an open conversation with a healthcare provider about the risk of Hepatitis D.

Early detection and good care can go a long way in protecting the liver and leading a healthier life. As with most health concerns, awareness and action are key.
