  Purpose

The purpose of this study is to determine whether preemptive nucleoside analogue therapy or regular virologic monitoring is the preferred method in management patients with prior exposure to hepatitis B vius (HBV) and undergoing hematopoietic stem cell transplantation (HSCT).


Condition

Primary Outcome Measures:
  • HBV reactivation (defined as detectable HBV DNA >20 IU/mL) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    From date of hematopoietic stem cell transplantation (HSCT) to 2 years after HSCT.


Biospecimen Retention:   Samples Without DNA

Serum and plasma for hepatitis B virus genotypic, virologic and serologic testing


Estimated Enrollment: 50
Study Start Date: November 2011
Estimated Study Completion Date: February 2016
Estimated Primary Completion Date: November 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts
HBsAg-negative, anti-HBc-positive
HBsAg-negative, anti-HBc-positive subjects undergoing hematopoietic stem cell transplantation (HSCT)

Detailed Description:

Occult hepatitis B virus (HBV) reactivation has been documented in bone marrow transplantation recipients who are hepatitis B surface antigen (HBsAg)-negative but with serologic evidence of prior exposure to HBV. However detailed prospective studies documenting the incidence of reactivation and the virologic and serologic kinetics of reactivation are lacking. The investigators prospective study proposes to follow-up 50 such bone marrow transplant recipients with all serologic and virologic parameters monitored every 4 weeks. Patients with detectable HBV DNA will be started on nucleoside analogue therapy. The optimal method and duration of monitoring will also be determined from our study.
