Trial summary

Mother-to-child transmission (MTCT) is the most common route of hepatitis B virus (HBV) infection. After given standard immunoprophylaxis, MTCT still occurred in some infants born to a HBsAg positive mothers with high HBV DNA load. Read more about this study

About this study

Official title: Case-control Study of Antiviral Therapy During Entire and the Third Trimester of Pregnancy in Preventing MTCT of HBV in Mothers With High Serum HBV DNA Load

Mother-to-child transmission (MTCT) is the most common route of hepatitis B virus (HBV) infection. After given standard immunoprophylaxis, MTCT still occurred in some infants born to a HBsAg positive mothers with high HBV DNA load. The main purpose of this study is evaluating the efficacy of methods used in blocking MTCT of HBV in infants born to a HBsAg positive mothers with high serum HBV DNA loads.

Read the detailed description

This study contain 600 patients and compose groups as follow: (ⅰ) infants born to a HBsAg positive mothers with high HBV DNA load before delivery receive standard immunoprophylaxis( injection of HBIG 200IU at birth plus HBV vaccine at 0,1 and 6month); (ⅱ) infants born to a HBsAg positive mother with high HBV DNA load before delivery, and based on standard immunoprophylaxis receive addition injection of HBIG 200IU at 1 month after birth; (ⅲ) infants born to a HBsAg positive and high HBV DNA load mothers but treated with antiviral therapy in late pregnancy, receive standard immunoprophylaxis; (ⅳ) infants born to a HBsAg positive mothers treated with antiviral therapy during entire pregnancy for hepatitis receive standard immunoprophylaxis; (ⅴ) infants born to a HBsAg positive mother with serum HBV DNA negative receive standard immunoprophylaxis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • telbivudineDrug

    in telbivudine treatment entire pregnancy group, mothers were treated with telbivudine during entire pregnancy for hepatitis B.

    in telbivudine treatment in late pregnancy group, mothers with high serum HBV DNA load receive telbivudine treatment in late pregnancy for preventing MTCT of HBV.
