Prevention × Misunderstanding Pregnant women have hepatitis, can it be transmitted to their babies?

At present, hepatitis B is the main prevention and treatment method of gestational liver disease in Taiwan Province province. After the comprehensive application of hepatitis B vaccine in newborns, the prevalence rate also dropped significantly. Except fulminant hepatitis, we only need proper rest and treatment. Most hepatitis is not in immediate danger, but we should be careful not to develop into chronic diseases. What are the types and transmission routes of hepatitis?

At present, viral hepatitis is divided into five types: A, B, C, D and E. The common types are hepatitis A, hepatitis B and hepatitis C. Besides viral hepatitis, there are also hepatitis caused by alcohol, drugs or poisons. The common symptoms of hepatitis are fever, chills, sweating and muscle pain, loss of appetite, nausea and vomiting. These symptoms are very similar to a cold, but if there is no jaundice, it is difficult to see that it is a hepatitis attack.

Hepatitis A is acute and will not cause chronic carriers, so hepatitis A is not the focus of prevention and treatment during pregnancy. The transmission route of hepatitis A is usually that the virus enters the body through the mouth, so it will not be transmitted vertically to the fetus. Like hepatitis B, hepatitis C is transmitted through blood, body fluids or wounds. However, according to statistics, the virus of hepatitis C usually does not increase significantly during pregnancy, and it is less likely to be transmitted to the baby. Another point is that there is no vaccine for hepatitis C at present, and vaccination cannot prevent it.

Therefore, hepatitis B is the main protection of liver disease during pregnancy, and the route of infection is blood and body fluids, and mother-to-child vertical transmission. If public health is not done well in the past, hepatitis B may occur. In Taiwan Province Province, more than 90% newborns have hepatitis B antibodies after 1984 was fully vaccinated with hepatitis B vaccine. However, people over the age of 32 and over the age of 3 have not been fully vaccinated with hepatitis B vaccine, so there is still a certain proportion of hepatitis B carriers.

How to prevent the baby from getting hepatitis B?

The route of transmission to newborns is vertical transmission, which may be transmitted by mothers with hepatitis B during pregnancy or childbirth, because the fetus is not easy to produce antibodies to eliminate the virus, which may lead to lifelong infection, increase the risk of liver disease, and even lead to cirrhosis and liver cancer. Detection of hepatitis B will check two antigens, one is S antigen (surface antigen) and the other is E antigen, which is also highly contagious. E antigen and S antigen are usually checked at the first blood test in early pregnancy. If Mommy E antigen is positive, the baby born has a 90% chance of becoming a carrier of hepatitis B..

Therefore, if Mommy is positive for hepatitis B E antigen, it is necessary to further detect the virus amount. If the amount of virus is high and she has not received treatment, there is a certain chance of vertical transmission to her baby. In addition, invasive examination such as amniocentesis is not recommended, which may increase the risk of fetal infection. At present, there are drugs that can reduce the amount of virus in patients with hepatitis B, and hepatitis B immunoglobulin can also be given. When using these drugs during pregnancy, you must consult experts in hepatobiliary and gastrointestinal departments for treatment to reduce the chance of your baby being infected with hepatitis B.

The most important thing for hepatitis B prevention and treatment is to inject hepatitis B vaccine. As long as they are normal and healthy pregnant women or pregnant women with few viruses, the first injection of hepatitis B vaccine should be given within 24 hours after the baby is born, the second injection 30 days later and the third injection 6 months later. However, it may not be enough to vaccinate infants with E antigen positive carriers. After birth, in addition to hepatitis B vaccine, more hepatitis B immunoglobulin will be inoculated, and HBsAg& will be detected after the baby reaches 1 year. Anti-HBsAb, check for antibodies within 24 hours. If there is no antibody and the antigen is positive, it should be handed over to a specialist for follow-up treatment.
