Questions from Hepatitis B carriers?

Is it true that a person who is a carrier of hepatitis B will never be able to clear the virus and be cured for life? It seems that people tend to avoid individuals with this condition, believing that being a carrier will "definitely" lead to disease.
Does being a carrier mean that one is destined to experience liver damage in the future, causing widespread anxiety? Additionally, if a carrier has children, is there a risk that the children will also become carriers? What about combinations such as a carrier father with an antibody-positive mother, a carrier father with a carrier mother, or a carrier father with a mother who has neither antibodies nor antigens? Aren't these scenarios potentially dangerous for the next generation? Thank you for your response; I am truly troubled by this.

Hello, Dr.
Dai:
1.
A hepatitis B carrier is defined as HBsAg positive and HBsAb negative.
The term "carrier recovery" refers to the conversion of HBsAg to negative and HBsAb to positive.
The spontaneous seroconversion rate is generally low, so hepatitis B carriers require lifelong monitoring.
2.
Most carriers are healthy, but a small percentage may progress to chronic hepatitis, cirrhosis, or liver cancer.
3.
The primary mode of transmission for hepatitis B is through body fluids.
The transmission routes are:
1.
Vertical transmission, where the mother transmits the virus to the child through the placenta.
However, with the administration of immunoglobulin and hepatitis B vaccines to newborns, the infection rate can be significantly reduced.

2.
Horizontal transmission, which refers to infection through contact with hepatitis B-infected blood, such as through the use of contaminated needles, blades, tattoos, or eyebrow tattoos.
4.
If parents are carriers, children can receive the vaccine to prevent blood transmission behaviors, such as sharing blades, razors, contact with wounds, or sharing toothbrushes.
Wishing you good health.
Sincerely,
Dr.
Ming-Hui Lin, Taoyuan Hospital, Department of Health

More Info

Hepatitis B is a viral infection that affects the liver and can lead to both acute and chronic diseases. Understanding the implications of being a Hepatitis B carrier is crucial, especially considering the myths and misconceptions surrounding the condition.
Firstly, it is important to clarify that being a Hepatitis B carrier (indicated by the presence of Hepatitis B surface antigen, or HBsAg) does not necessarily mean that an individual will develop liver disease. There are different categories of Hepatitis B infection: healthy carriers, chronic hepatitis, and cirrhosis. Healthy carriers often have normal liver function and may not experience any symptoms or complications throughout their lives. In contrast, individuals with chronic hepatitis or cirrhosis are at a higher risk of developing liver cancer and other serious liver-related issues.

The notion that all Hepatitis B carriers will inevitably develop liver disease is a myth. While it is true that chronic infection can lead to liver complications, many carriers maintain stable liver function for years without any significant health issues. Regular monitoring and medical check-ups are essential for managing the health of Hepatitis B carriers. This includes routine blood tests to assess liver function and the presence of viral load, as well as imaging studies to monitor liver health.

Regarding the transmission of Hepatitis B to offspring, the risk of a child becoming a carrier largely depends on the mother's Hepatitis B status during childbirth. If a mother is a carrier (HBsAg positive), there is a significant risk (up to 90%) of transmitting the virus to her newborn during delivery. However, if the mother has developed antibodies against Hepatitis B (anti-HBs positive), the risk of transmission is greatly reduced.
In scenarios where the father is a carrier and the mother has antibodies, the child is at a lower risk of becoming a carrier. Conversely, if both parents are carriers, the child has a higher risk of being infected. If the mother is not a carrier but has no antibodies, the child should be vaccinated against Hepatitis B shortly after birth to prevent infection.

It is also worth noting that Hepatitis B can be managed effectively with antiviral medications, which can help reduce the viral load and minimize liver damage. For those who are carriers, treatment decisions should be based on liver function tests, the presence of liver inflammation, and the risk of disease progression.
In summary, being a Hepatitis B carrier does not equate to a life sentence of inevitable liver disease. With proper medical care, many carriers can live healthy lives without significant complications. Education about the disease, regular monitoring, and preventive measures for offspring are vital in managing the risks associated with Hepatitis B. If you have concerns about your health or the health of your family members, it is essential to consult with a healthcare provider who specializes in liver diseases for personalized advice and management strategies.
