Women concern pregnancy HBV in

In Chinese population overall hepatitis b surface antigen (HBsAg) carry rate had fallen to 7.18%,5  children under the age of only 0.96%. But in adults aged over 20, HBsAg carrying rate still amounted to an average of 10%, which included women of reproductive age. Research shows that of HBsAg carrying rate in pregnant women is about 5%, according to projections, each year approximately 706,000 HBV infection in pregnant women. HBV infection in pregnant women not only threaten the health of pregnant women themselves, are also available through mother to child transmission, affect the health of infants. Dealing with HBV infection in pregnant women and other related issues is essential for HBV infection rates in further reducing the next generation. Treatment of HBV infection in pregnant women and different from the general population, the academic community on many issues in this area has not yet reached a consensus, clinically, there are also many misconceptions. Take the 2011 world hepatitis day approaching, we launched thematic reports on HBV infection in pregnant women, for readers ' reference. 1 to HBV mother-infant transmission, scientific work——  a clinical first-line letter from liver disease doctor to prevent HBV transmission problems, updated in 2010 the prevention and treatment of chronic hepatitis b guide has a detailed recommended. Author liver disease specialist working in line, found medical profession in blocking measures to publicize HBV transmission and definitions, some even overlook the basic strategy means of prevention focusing on some immature or invalid, relying on timing prevention, adverse consequences occur. I am where I needed to be serious discussion of these issues.first, in late pregnancy, HBsAg-positive women each month 1 injection of hepatitis b immunoglobulin (HBIG) may reduce mother to child transmission did? This method is not evidence-based medicine has been implemented for years if proved to be effective, still seen in many popular science articles. This led to a lot of waste of medical resources.second, third trimester antiviral therapy can prevent HBV transmission, please? &Nbsp; in recent years, some studies show that in late pregnancy, HBsΑg-positive, high viral load of the women received antiviral treatment may reduce the risk of HBV infection in neonates. But evidence insufficient, new hepatitis b article has not recommended in late pregnancy preventive use antiviral drugs. Worth noting is that we have seen some emphasized that the antiviral treatment is the key to block the transmission, pointing out that “ HBV-infected couples plan pregnancies must be before antiretroviral therapy. Decided such views and is clearly inappropriate may mislead some grassroots medical workers and masses.third, Caesarean section can do blocking HBV transmission? Obstetrics is inconsistent about this view, there are advocates for cesarean section in HBV-positive pregnant women to reduce mother to child transmission. If you are only considered from exposure to virus infection risk, cesarean birth process short, baby skin and mucous membrane damage opportunities, risk of infection is low. But it is certainly not a substitute for neonatal immunization, immunization of which will be implemented, in particular the immediate injection of adequate amounts of HBIG, even with the virus exposure, is sufficient to protect against infection. In addition, the surgery itself is at risk, relatively high costs, coupled with the benefits of natural childbirth for children, this little disadvantage caesarean section is clearly on the grounds of.IV, HBsAg-positive mothers breastfeeding yet? &Nbsp; This is in fact already concluded problem. 2005 edition of the Guide to prevention and treatment of chronic hepatitis b has made it clear that “ newborns born within 12 hours of injection HBIG  and hepatitis b vaccine, the acceptable HBsAg  positive mothers breastfeeding ”. But from the Internet or in a number of popular science propaganda, some experts also is constantly
