EBV Viral Load Monitoring: Unanswered Questions

Measurement of the Epstein-Barr Virus (EBV) load in the peripheral blood using DNA amplification techniques has become increasingly available for the management of organ transplant recipients (1). In this volume of the American Journal of Transplantation, Tsai and colleagues add to our knowledge of this test by exploring the use of EBV PCR for the diagnosis and management of post-transplant lymphoproliferative disorders (PTLD) in adult solid organ transplant (SOT) recipients (2). As most published experience to date has been derived from pediatric organ transplant or bone marrow transplant recipients, analysis of data derived from adult SOT is necessary to determine whether or not results obtained from this population will be similar to findings from children and marrow recipients. The findings that EBV viral loads obtained from adult SOT recipients undergoing evaluation for PTLD were highly specific but only marginally sensitive contrast with previously published work, which has typically found the EBV viral load to be extremely sensitive but to lack specificity for the presence of EBV-associated disease (1–3).
