Hepatitis D is the most severe form of viral hepatitis, yet it remains one of the least known. What makes it unique is that it can only infect people who are already infected with hepatitis B. Understanding the specific hepatitis D causes and being able to recognize potential hepatitis D symptoms is vital because this dual infection can rapidly accelerate liver damage. A clear hepatitis D diagnosis is the first step toward management, and while hepatitis D treatment options have been limited, new therapies are providing hope. This guide explains this complex liver disease. Log on to www.doralhw.org for a consultation.
The Unique Hepatitis D Causes and Transmission
The hepatitis D virus (HDV) is considered an “incomplete” or “satellite” virus. It cannot replicate on its own. Instead, it needs the hepatitis B virus (HBV) to survive and multiply. Therefore, the primary cause of hepatitis D is having a pre-existing hepatitis B infection.
There are two main ways a person can get hepatitis D:
- Coinfection: This occurs when a person is infected with both hepatitis B and hepatitis D at the same time. While this can cause a severe acute illness, most adults who experience a coinfection will clear both viruses and recover fully.
- Superinfection: This is more dangerous. It happens when someone who already has chronic hepatitis B later becomes infected with hepatitis D. A superinfection is much more likely to lead to a chronic hepatitis D infection, which significantly increases the risk of severe liver disease.
HDV is transmitted the same way as HBV—through contact with infected blood or body fluids. This most commonly occurs through sharing needles for drug use or through unprotected sexual contact with an infected person. An infectious disease specialist can provide detailed guidance on preventing transmission.
Recognizing Hepatitis D Symptoms
The symptoms of hepatitis D are very similar to those of other forms of hepatitis, making it impossible to distinguish based on symptoms alone. Many people may not have any symptoms, especially in the early stages.
When hepatitis D symptoms do appear, they can include:
- Jaundice (yellowing of the skin and eyes)
- Fatigue and weakness
- Abdominal pain, particularly in the upper right side near the liver
- Loss of appetite
- Nausea and vomiting
- Joint pain
- Dark urine
Because superinfection can cause a rapid progression of liver disease, a person with chronic hepatitis B who suddenly feels much sicker should be evaluated for hepatitis D.
The Process for a Hepatitis D Diagnosis
Since the symptoms are non-specific, a hepatitis D diagnosis can only be confirmed through blood tests. This testing is typically recommended for anyone who has a confirmed hepatitis B infection, especially if they show signs of worsening liver disease.
The diagnostic steps include:
- Hepatitis D Antibody (Anti-HDV) Test: The initial test looks for antibodies to the hepatitis D virus in the blood. A positive result indicates a past or present infection.
- HDV RNA Test: If the antibody test is positive, this second test is performed to detect the virus’s genetic material (RNA). A positive RNA test confirms an active, current infection that may require treatment.
An infectious disease specialist is the best provider to manage the diagnosis and subsequent care, as they have expertise in these complex viral infections.
Hepatitis D Treatment and Management
The goal of hepatitis D treatment is to suppress the virus and prevent the progression of liver damage to cirrhosis or liver cancer. For a long time, treatment options were limited and not very effective.
Traditional and Emerging Therapies
- Pegylated Interferon: For many years, weekly injections of pegylated interferon alfa-2a were the only available treatment. This therapy has low success rates and can cause significant side effects, limiting its use.
- Newer Medications: Fortunately, the landscape is changing. A new medication, bulevirtide, has been approved in Europe and works by blocking the virus from entering liver cells. While not yet approved in the US, it is available through clinical trials. This and other emerging therapies are offering new hope. An infectious disease specialist in Brooklyn can provide information on accessing clinical trials.
All individuals with chronic hepatitis D require regular monitoring of their liver health, including blood tests and ultrasounds to screen for liver cancer.
The Best Prevention: The Hepatitis B Vaccine
The most effective way to prevent hepatitis D is to prevent hepatitis B. The hepatitis B vaccine is safe and highly effective. Since you cannot get hepatitis D without first having hepatitis B, getting vaccinated against HBV also protects you from HDV. The vaccine is recommended for all infants, children, and adults who have not been vaccinated.
Hepatitis D is a serious and aggressive liver disease that requires expert management. While the symptoms are often vague, their impact on the liver can be severe. A prompt diagnosis and a partnership with a knowledgeable healthcare provider are crucial for protecting your health.
If you have hepatitis B, it is vital to get tested for hepatitis D. If you are diagnosed with a coinfection or superinfection, seeking care from an expert is the next step.
