Abstract
We report a case of hepatitis B virus reactivation that occurred after immunosuppressive treatment in a hepatitis B surface antigen-negative patient with detectable antibodies to hepatitis B core antigen and hepatitis B surface antigen. Sequence analysis revealed an 11-bp insertion in the core promoter region of hepatitis virus DNA, creating a novel hepatocyte nuclear factor-1 binding site. This led to enhanced viral replication and fulminant hepatitis.
