Patient's question:
Detailed medical condition and consultation purpose: I am a late-pregnant patient with chronic hepatitis B.Doctor's answer:
Hello, how is your liver function test? If your mother is an HBV carrier (commonly known as HBsAg positive), she should first check the status of HBV antigens and antibodies in her body. If only HBV antigens are present in her body without antibodies, the child should receive a dose of high-efficiency immunoglobulin immediately after birth, along with a vaccine. Once the high-efficiency immunoglobulin enters the body, it will immediately provide protection, preventing the child from infection. After the child receives the vaccine (not the high-efficiency immunoglobulin), it usually takes about 3 months to develop the corresponding antibodies. After this treatment, the mother can breastfeed the child.If the mother has antibodies to HBV in her body that pass through the placenta, they can provide protection for the child. After birth, the mother can breastfeed the child, and the child does not need to receive immunoglobulin but still requires the HBV vaccine.
For mothers with chronic hepatitis B (HBsAg and anti-HBc positive), it indicates that the HBV is actively replicating in their body, increasing the risk of infection for the child. After birth, the child should receive both immunoglobulin and the HBV vaccine. The mother should avoid breastfeeding the child and minimize close contact, as sweat and saliva can also transmit the HBV virus to the child.
