Hepatitis B reactivation in patients with multiple myeloma and isolated positive hepatitis B core antibody: a call for greater cognizance

Hepatitis B reactivation in patients with multiple myeloma and isolated positive hepatitis B core antibody: a call for greater cognizance.

Hepatitis B virus (HBV) reactivation is a well-established complication of severe immunosuppression in patients with hematologic malignancy and positive hepatitis B surface antigen (HBsAg). Patients who receive high-dose chemotherapy, corticosteroids, rituximab, or have a bone marrow transplant are particularly at increased risk for HBV reactivation. However, limited information is available in...

can Isolated hepatitis B core antibody in HIV-infected patients response to hepatitis B vaccine help to elucidate the cause?

Significance of Hepatitis B Core Antibody as the Only Marker of Hepatitis B Virus Infection in High Risk Patients

  Background and Objective: Presence of hepatitis B core antibody (anti-HBc) in the absence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) is defined, as isolated anti-HBc. little is known about the clinical significance of the isolated anti-HBc in hepatitis B virus (HBV) infections. The aim of this study was to assess the significance of anti-HBc as the onl...

Reactivation of hepatitis B virus without core antibody.

We present the case of a male patient not vaccinated against hepatitis B virus (HBV) and with reactivity to a surface antibody who, after immunosuppression for a multiple myeloma, had HBV reactivation. Pharmacological HBV suppression was tried, but viremia could not be suppressed. Production-detection core mutations or immunity issues can explain this clinical phenomenon.

Reactivation of hepatitis B virus with mutated hepatitis B surface antigen in a liver transplant recipient receiving a graft from an antibody to hepatitis B surface antigen– and antibody to hepatitis B core antigen–positive donor

BACKGROUND Fresh-frozen plasma (FFP) may contain antibodies to hepatitis B surface antigen (HBsAg, anti-HBs). These anti-HBs may lead to a misinterpretation of the actual hepatitis B immune status. Furthermore, they may not only confer protection against hepatitis B virus (HBV), but may also favor the selection of HBsAg mutants. CASE REPORT We report a case of de novo HBV infection in a HBV-n...
