Case 1: A 29-year-old woman who is planning to get pregnant and has a HBVDNA of 10 to the fourth power and an ALT of 98 U/L in a pre-pregnancy test. Will it be contagious? What treatment do I need? Example 2: Female, 27 years old 15 weeks pregnant, first found to have hepatitis B. ALT19U/L AST21U/L HBVDNA10 4th power And I am 15 weeks pregnant, currently eating without taste, eating less. Help wanted: How much does this disease affect the baby? Do I need to terminate the pregnancy? Will I infect others? Will I get hepatitis B, or cirrhosis in the future? Case 3: 31 year old female 26 weeks pregnant with HBVDNA 10 to the 8th power. Liver function is normal. Will I be infectious? Will I develop the disease? Pregnancy with hepatitis B infection is a concern, not only for the adults themselves, but also for the possibility of “passing on” (actually transmitting) hepatitis B to the next generation. This increases parental anxiety. What can you do about it? Best option: Pregnancy tests, including Hepatitis B tests, HBVDNA, and liver function, should be done before you plan to get pregnant. If the woman’s parents, her parents’ brothers or other relatives have suspected hepatitis or have passed away due to ascites liver disease, liver disease should be suspected and must be checked before pregnancy! In the case of example 1, which was found before pregnancy, at this time the liver function is abnormal, you can perform interferon antiviral treatment for 1 year before considering pregnancy. This is to protect both the adult and the child. If you don’t get tested before you get pregnant and find out after you get pregnant. In case 2, the liver function is normal and the virus is low (<10 to the sixth power), then regular review without treatment is possible. Example 3 is also a case of normal liver function but high viral count, >6th power of 10, which requires treatment to prevent transmission to the child. Try to use tenofovir and tipifudine, and the course of treatment is from 28 weeks of pregnancy to 3 months after the child’s delivery. In short, pregnancy combined with hepatitis B infection, treatment to consider the impact of drugs on the fetus, but also to avoid the transmission of the virus is complex. It is recommended to improve the examination before pregnancy and to treat the infection as soon as possible after pregnancy.
