Hepatitis B virus is an infection that can be easily transmitted from women to newborns at the time of delivery. Our objective is to identify novel options that are effective and safe in preventing perinatal transmission of hepatitis B in Africa. The REVERT-B study (Reducing Vertical Transmission of Hepatitis B in Africa) is a clinical trial designed to test a new strategy of using antiviral medication in high-risk pregnant women and newborns to reduce the risk of hepatitis B transmission. The study will measure efficacy, safety, tolerability and adherence to medication.
China is a highly prevalent area of hepatitis B virus（HBV） infection, with at least 75 million hepatitis B virus carriers, and 80% of primary hepatocellular carcinoma (HCC) is associated with chronic hepatitis B virus infection. Liver transplantation is currently the preferred method for end-stage liver disease such as biliary atresia and cirrhosis in children. In recent years, children's liver transplantation has developed rapidly and the number of developments has increased significantly. If there is chronic hepatitis B virus infection in the donor liver, it may cause HBV transmission, or the patient may have a low-load occult hepatitis B virus infection, and after immunosuppressive treatment, it may lead to hepatitis B virus infection after surgery.
Immunoprophylaxis with two hepatitis B vaccinations following the hepatitis B immune globulin (HBIg) and hepatitis B vaccine at birth is largely effective in protecting infants from hepatitis B virus (HBV) infection. However, hepatitis B infection due to immunoprophylaxis failure often occurs in approximately 10% of infants who are born to highly viremic mothers with HBeAg-positive. Maternal HBV DNA > 200,000 IU/mL is the major independent risk for mother-to-child transmission (MTCT). A recent randomized controlled trial has shown that Tenofovir Disoproxil Fumarate (TDF) use during the third trimester of pregnancy could safely reduce the rate of MTCT with few adverse effects when combined with the administration of the standard immunoprophylaxis to the infants. However, HBIg is expensive and not available in many developing countries, resulting approximately 30% of infant infection when they received only HBV vaccination. The present study aims to investigate if highly viremic mothers who are treated with TDF from the second trimester to delivery in combination of infant's standard series of HBV vaccinations (omission of HBIg) have a comparable MTCT rates, when compared to those of mothers who receive TDF at the third trimester in combination of infant's standard HBV vaccinations and a birth dose of HBIg.
