Let's Learn About Hepatitis D: It's Quite Unique! | Nirogi Lanka

You may have heard about various liver conditions, but today at Nirogi Lanka, we want to discuss a rather unique and critical one: Hepatitis D. Let's take a closer look at what makes this virus distinct, how it impacts your health, and the essential steps you can take to protect yourself.

What is Hepatitis D?

Simply put, Hepatitis D is a viral infection that causes inflammation of the liver. However, what makes this virus truly unique is that the Hepatitis D virus (HDV) cannot cause an infection on its own. It sounds surprising, doesn't it? To replicate and cause disease in your body, the virus must coexist with the Hepatitis B virus (HBV). This means you can only contract Hepatitis D if you are already infected with Hepatitis B, or if you contract both viruses simultaneously. It simply cannot survive or cause illness alone.

Hepatitis D infections generally fall into two categories:

1. Acute Infection: Symptoms appear relatively quickly and may last for several weeks or months. In some cases, your body may clear the infection on its own.

2. Chronic Infection: This is the more serious form. An acute infection may progress into a chronic state, where symptoms persist for more than six months. This can lead to long-term, permanent damage to your liver.

What are the types of Hepatitis D?

Let's take a closer look at the two primary ways you can contract Hepatitis D.

What is Coinfection?

Coinfection occurs when you are infected with both the Hepatitis B virus (HBV) and the Hepatitis D virus (HDV) at the exact same time. Think of it as a simultaneous attack by both viruses. In these cases, the symptoms are often similar to a standard Hepatitis B infection but can be significantly more severe. However, there is some good news: when you are infected with both at the same time, the likelihood of the infection becoming chronic is generally lower.

What is Superinfection?

Superinfection is a different, higher-risk scenario. This happens when you already have an existing Hepatitis B infection (perhaps a chronic one) and you are then newly exposed to the Hepatitis D virus. It is like adding a new layer of illness to an existing one. When a superinfection occurs, your previous Hepatitis B symptoms may suddenly reappear or feel far more intense. In most cases (about 90%), this type of superinfection progresses to a chronic state. This means the infection can stay in your body for a long time, increasing the rate at which your liver may be damaged.

What are the symptoms of Hepatitis D?

The symptoms of Hepatitis D are very similar to other forms of hepatitis. Some people may not show any symptoms at all. However, if symptoms do occur, you might experience the following:

• Fever.
• Abdominal pain, particularly in the upper right side of your belly (where your liver is located).
• Nausea and vomiting.
• Loss of appetite, where you have no desire to eat.
• Dark-colored urine, often resembling the color of tea.
• Conversely, your stools may become pale or clay-colored.
• Yellowing of the skin and eyes—a condition known as jaundice. This happens when your liver is unable to effectively process bilirubin.
• Persistent fatigue or tiredness.

A Hepatitis D infection can also cause any pre-existing symptoms of Hepatitis B to worsen significantly.

What causes Hepatitis D?

The cause is the Hepatitis Delta Virus (HDV). However, as mentioned, it cannot act alone. It relies entirely on the Hepatitis B virus (HBV) to survive and replicate. Therefore, to develop Hepatitis D, you must have the HBV virus present in your body.

How is Hepatitis D transmitted?

Hepatitis D is transmitted in the same way as Hepatitis B: through contact with the blood or other bodily fluids (e.g., semen, vaginal secretions) of an infected person. Key transmission routes include:

• Unprotected sexual contact (not using a condom during vaginal, oral, or anal intercourse).
• Sharing needles or syringes used for injecting drugs. Using medical equipment that has not been properly sterilized can also pose a risk.
• Needlestick injuries for healthcare workers while caring for patients.
• Mother-to-child transmission during childbirth. This is less common, especially if appropriate preventative measures are taken.
• Getting tattoos or piercings using non-sterile equipment also carries a significant risk.

Who is at higher risk of contracting Hepatitis D?

The following groups are at a higher risk of contracting Hepatitis D from Nirogi Lanka’s perspective:

• Individuals already infected with Hepatitis B (HBV): Hepatitis D cannot exist without the presence of Hepatitis B.
• People who inject drugs: Especially those who share needles or other equipment.
• Sexual partners: Anyone who has sexual contact with a person who has both HBV and HDV.
• Household members: Those living with someone who has HBV and HDV, particularly if personal items like razors or toothbrushes are shared.
• People with HIV infection.
• Men who have sex with men: Especially in cases of unprotected sexual activity.
• Healthcare workers: Or those in other fields where frequent exposure to blood or bodily fluids is common.
• Individuals with kidney disease undergoing hemodialysis.

What are the potential complications of Hepatitis D?

Hepatitis D, especially if it becomes chronic, can cause severe damage to your liver. Key complications include:

• Cirrhosis: This is the scarring of your liver tissue. Over time, as your liver becomes stiffer and more scarred, it loses its ability to function correctly, similar to how a deep wound on your skin leaves a permanent mark.
• Liver failure: This is a critical condition where your liver is no longer able to perform its vital tasks, posing a direct threat to your life.
• Hepatocellular carcinoma: This is a type of primary liver cancer. If you have chronic Hepatitis D, your risk of developing this cancer is significantly higher.

How is Hepatitis D diagnosed?

If you suspect you have symptoms of Hepatitis D or belong to a high-risk group, the best step is to consult a physician for testing. Diagnosis is primarily achieved through blood tests. Your laboratory will check for the presence of viral particles (HDV RNA) or antibodies your body has produced to fight the virus (Anti-HDV antibodies).

Additionally, to assess your liver health and the extent of any scarring, your doctor may recommend an ultrasound, a FibroScan, or elastography. In some cases, a liver biopsy (a small sample of liver tissue) may be required.

Is there a complete cure for Hepatitis D?

To be honest, there is currently no definitive cure for Hepatitis D. However, acute HDV infections, particularly in co-infection cases, can sometimes resolve on their own without treatment.

For those living with chronic Hepatitis D, doctors focus on managing the virus, reducing liver damage, and preventing further complications. Possible treatments include:

• Peginterferon alfa injections: These are typically administered once a week for about a year to help your immune system fight the infection. Please be aware that this can cause side effects.
• Bulevirtide (Hepcludex®): This is a newer antiviral medication that prevents the HDV virus from entering your liver cells. While approved for treatment in several countries, availability may vary.
• Liver transplant: If your liver has suffered extensive damage and is no longer functioning, a liver transplant may be the final treatment option.

Research into new treatment methods is ongoing at Nirogi Lanka and around the world.

What happens if I have Hepatitis D?

If you are diagnosed with Hepatitis D, your physician will keep a close watch on your liver health. This involves regular check-ups, ongoing blood tests, and imaging scans. Acute HDV or HBV/HDV co-infections may clear up within weeks or months.

However, superinfections often progress to chronic Hepatitis D, which can persist for years. Your medical team may plan treatment protocols lasting a year or longer.

What is the prognosis for Hepatitis D?

Death from acute HBV/HDV co-infection is very rare (roughly 1-5%), though recovery can take weeks or months.

However, chronic HBV/HDV superinfection is serious. Between 70% and 80% of individuals with this condition may develop cirrhosis over time. This can occur rapidly—sometimes within the first two years—or progress slowly over 5 to 10 years. Unfortunately, a significant portion of those with chronic Hepatitis D (reportedly around 15% within 5-10 years) face severe complications such as liver failure or liver cancer. This is why prompt diagnosis and expert management are essential.

Can Hepatitis D be prevented?

Yes, absolutely! The best and most effective way to protect yourself against Hepatitis D is to prevent Hepatitis B. This is because Hepatitis D cannot develop in your body without the presence of Hepatitis B.

• Get vaccinated against Hepatitis B. This is the single most important step. The vaccine is highly safe and effective. If you have not yet been vaccinated, it is crucial that you speak with your doctor to receive it.
• If you suspect you have been exposed to Hepatitis B (for example, through contact with the blood of an infected person), seek medical attention immediately. You may be eligible for a dose of the vaccine, as well as Hepatitis B immune globulin (HBIG), which should be administered within 24-48 hours to help prevent the infection from taking hold.

If you are already living with Hepatitis B, you can reduce your risk of a "superinfection" by taking these precautions:

• Always wear sterile gloves if you anticipate contact with blood, wound drainage, or other bodily fluids.
• Never share needles, syringes, or any equipment used for injecting medications.
• Do not share personal hygiene items like toothbrushes or razors, as they may carry trace amounts of blood.
• Use condoms consistently during any type of sexual activity.
• If your doctor has prescribed antiviral medications for Hepatitis B, ensure you take them exactly as directed.

If you are pregnant and living with Hepatitis B or a coinfection (HBV/HDV), doctors can take specific steps immediately after your baby is born to provide vaccinations and necessary treatments to significantly reduce the risk of transmission to your child.

How can I care for my health while living with Hepatitis?

If you have Hepatitis (B or D), there are several steps you can take to protect your liver from further damage:

• Avoid alcohol entirely. Alcohol places immense stress on liver cells, which your liver may struggle to handle if it is already inflamed.
• Stop smoking or avoid starting, as smoking is also detrimental to liver health.
• Maintain a healthy weight. Being overweight or obese can contribute to fatty liver disease, which can worsen your overall liver condition.
• Consult your doctor or a nutritionist for personalized advice on the best diet to support liver health. A balanced diet is essential.
• Check with your doctor before taking any over-the-counter (OTC) medications. For instance, frequent use of pain relievers like Acetaminophen (Tylenol®) can be hard on your liver. Only use such medications under medical guidance.
• Stay committed to your follow-up appointments and complete all recommended liver health screenings. This is vital for monitoring your progress.

When should I see a doctor?

If you develop symptoms of hepatitis (such as fever, body aches, loss of appetite, or jaundice), or if you already have Hepatitis B and notice a sudden worsening of your symptoms, you must see your doctor. Additionally, if you believe you have been exposed to Hepatitis B or D, seek medical advice promptly.

When should I go to the Emergency Department?

Seek immediate emergency medical attention if you experience any of the following severe symptoms:

• Severe abdominal pain.
• Persistent or severe vomiting, especially if you cannot keep liquids down.
• Vomiting blood or material that looks like coffee grounds.
• Worsening jaundice (intense yellowing of your eyes or skin).
• Confusion, disorientation, or difficulty staying awake (these can be signs of Hepatic Encephalopathy).
• Dark-colored urine or a significant decrease in urine output.
• Pale or clay-colored stools.
• Significant abdominal swelling.

These may be signs of severe liver distress or failure.

What questions should I ask my doctor?

At Nirogi Lanka, we encourage you to be an active participant in your care. When you meet with your physician, consider asking:

• What specific type of hepatitis do I have?
• What are my treatment options?
• How long will I need to remain on this treatment?
• What is the correct way to take my medication, and what are the potential side effects?
• Are there specific new symptoms or changes I should watch out for?
• What is the current status of my liver, and what further tests are needed?
• What precautions should I take to prevent spreading this to others?
• If I have Hepatitis B, what else can I do to prevent contracting Hepatitis D?

What is the difference between Hepatitis B and Hepatitis D?

Hepatitis B and Hepatitis D are both viral infections that specifically target your liver. The crucial difference is that Hepatitis D can only infect you if you already have Hepatitis B. The Hepatitis D virus (HDV) acts like an "incomplete" virus; it cannot survive or replicate on its own and relies entirely on the "help" of the HBV virus to cause an infection.

It is important to know that not everyone with Hepatitis B will develop Hepatitis D. In fact, most people living with Hepatitis B do not have Hepatitis D.

How common is Hepatitis D?

Experts estimate that 5% to 15% of people living with Hepatitis B worldwide—approximately 12 to 45 million individuals—are also infected with HDV. Hepatitis D is most prevalent in certain parts of Africa (such as Central Africa), Asia (e.g., Mongolia, Pakistan), the Amazon basin in South America, and parts of Eastern Europe. It is less common in the United States and Western Europe. While it is not widely prevalent in Sri Lanka, the risk remains, and caution is advised.

Because the Hepatitis D virus requires the Hepatitis B (HBV) virus to cause an infection, your strategy for protection is straightforward: every measure you take to prevent HBV infection also protects you from Hepatitis D. Furthermore, thanks to the widespread use of the Hepatitis B vaccine, the number of Hepatitis B and, consequently, Hepatitis D cases is steadily declining globally. This is vital, as many individuals can carry Hepatitis B without showing any symptoms at all.

If you have a chronic infection, work closely with your doctor to monitor your liver health regularly. Ongoing medical research into new therapies continues to offer hope for more effective treatment options in the future.

The most important takeaway

Hepatitis D is a unique liver condition. The most critical point to remember is that you cannot contract Hepatitis D unless the Hepatitis B virus is already present in your body. Therefore, preventing Hepatitis B is the most effective way to safeguard yourself against Hepatitis D.

Receiving the Hepatitis B vaccine, practicing safe sex, and never sharing needles or syringes are essential steps you can take to protect yourself from both Hepatitis B and Hepatitis D.

If you have already been diagnosed with Hepatitis B, please do not panic. It is essential to follow your doctor's medical advice, attend all scheduled screenings, and avoid substances that stress the liver, such as excessive alcohol or medications not prescribed by your healthcare provider. Doing so can significantly lower your risk of developing Hepatitis D.

Stay vigilant regarding any symptoms. If you have any concerns, consult your doctor promptly. Early detection is your best tool to minimize complications and maintain a healthy, active life with Nirogi Lanka.
