Reactivation of hepatitis B virus in two chronic GVHD patients after transplant

Abstract

We report two cases of hepatitis B virus reactivation following allogeneic bone marrow transplantation (BMT) for severe aplastic anemia and acute myelocytic leukemia. The presence of antibodies to HBsAg, HBeAg and HBcAg prior to transplant indicated previous infection with hepatitis B virus (HBV). These antibodies disappeared 2 and 4 months after the onset of chronic graft versus host disease (GVHD) following immunosuppressive treatment, but HBsAg reappeared in their sera 6 and 10 months later, respectively. This suggests that chronic GVHD and immunosuppressive drugs can reactivate HBV in HBsAb-positive patients, most likely because of the decrease in quality and function of helper T cells and B cells during chronic GVHD to induce clearance of HBV antibodies and reactivation of HBV. Our observation confirms that patients with HBsAb, HBeAb and HBcAb present in their sera should not be considered to have 'immunity' to HBV after BMT.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.
