Reactivation of the hepatitis B virus (HBV) with immunosuppressive status has been well established, mainly due to medications such as immunosuppressive therapy like cytotoxic chemotherapy, rituximab and biologic therapy, immunosuppression after solid and bone-marrow transplantation or long-term corticosteroids therapy. We report here two cases of HBV reactivation due to global hypogammaglobulinemia. Regular HBV serologic screening and PCR for HBV-DNA should be applied for each patient with primary immunosuppressive status and history of chronic HBV infection. The necessity of a preemptive treatment remains debated.
