1, hepatitis B virus infection are slow hepatitis B? Answer: After being infected with hepatitis B virus, most of the people will be clear of the virus, and they are healthy people (surface antibody can be found in the blood, or surface antibody, core antibody, e antibody or single core antibody can be found, and the antigens are all negative). And there are a small number of people whose virus cannot be completely clear, and they become chronically infected with hepatitis B virus. Chronic hepatitis B virus infected people are divided into several categories: The first type: inactive HBsAg carriers: serum HBsAg positive, HBeAg negative, anti-HBe positive or negative, HBV DNA is undetectable (PCR method) or lower than the lowest limit of detection, with more than 3 consecutive follow-up visits within 1 year, ALT are in the normal range, and liver histology is generally not obvious abnormality. The second type: chronic HBV carriers: serum HBsAg and HBV DNA positive, HBeAg or anti-HBe positive, but with more than 3 consecutive follow-up visits within 1 year, serum ALT and AST are in the normal range, and there is generally no obvious abnormality in liver histologic examination. The third type: chronic hepatitis B: HBV DNA positive, surface antigen positive, serum ALT persistently or repeatedly elevated, or hepatitis lesions on liver histologic examination. According to the e antigen, it is divided into two categories: e antigen-positive slow hepatitis B and e antigen-negative slow hepatitis B. 2.Hepatitis B virus DNA results how to read? Answer: such as: 2.57e6 or 2.57 E+06 IU/ml or copies/ml=2.57×10 to the sixth power, that is, 2570000 IU/ml or copies/ml. 3. Hepatitis B three series of tests: the three antibodies are positive, the surface antigen and the e antigen are all negative Is it infected with hepatitis B? Is it infected with hepatitis B? Do we need to take vaccination? A: This is not hepatitis B, and there is no need to take hepatitis B vaccine, so it is not contagious. If you are not sure, you can test HBVDNA to rule out viral mutation (the probability of this is very low). Positive for all three antibodies generally means that you were once infected with hepatitis B virus, but now the virus has been cleared and protective antibodies have been produced. You can repeat the test after half a year or one year. 4.Hepatitis B indicates that the quantitative value of antigen is high, does it mean that the virus is high and infectious? A: Hepatitis B surface antigen, that is, the shell protein of hepatitis B virus, itself is not infectious, but its appearance is often accompanied by the presence of hepatitis B virus, so it is a sign of infection with hepatitis B virus. However, there are two kinds of cases: First, the hepatitis B surface antigen is high, and the hepatitis B virus DNA is <1000, which generally indicates that there exists the surface shell of the hepatitis B virus in the body, and there is no hepatitis B virus DNA, there is no viral replication and contagiousness, so it only needs regular checkups. Second, the hepatitis B surface antigen is high, hepatitis B virus DNA>1000, it shows that there is a complete hepatitis B virus in the body, there is replication and infectiousness, the strength of the infectiousness should be decided according to the number of hepatitis B virus DNA. 5.Can hepatitis B be cured? Hepatitis B is generally The purpose of treatment is to control the disease. At present, there is no good program to cure hepatitis B (remove all the hepatitis B virus). After treatment for e antigen positive (also known as triple positive) hepatitis B, there is hope that the e antigen will become negative. However, there is no good treatment for surface antigen conversion. 6. Liver function is normal, liver ultrasound is normal, but hepatitis B virus is high, 6.5×10 to the seventh power, do I need antiviral? It means that you should be in the immunotolerance period of chronic hepatitis B, and antiviral treatment is not recommended at present. Maintenance is the main focus, pay attention to regular work and rest, avoid alcohol, regular review 7, liver function is normal, hepatitis C virus 5 × 10 of the 7th, need antiviral? Hepatitis C virus infected patients, regardless of liver function abnormalities, as long as the hepatitis C virus RNA positive, need antiviral treatment. Chronic hepatitis C treatment: at present, the most classical treatment is interferon + ribavirin.
