Objectives

Narrative objectives1

To clarify the significance of HBs-antigen as a monitoring examination for HBV reactivation in patients with previously resolved HBV infection, serum levels of HBs-antigen as well as HBV-DNA are measured repeatedly during immunosuppressive therapies, and entecavir administration is done when serum HBV-DNA levels increase up to 3 Log IU/mL and/or serum HBs-antigen becomes detectable.

Assessment

Primary outcomes

Both serum HBs-antigen and HBV-DNA are monitored repeatedly every 1 to 3 months during immunosuppressive therapies, and development of de novo HBV hepatitis is evaluated until 12 months after initiation of the therapies.
