Natural history of EBV replication and viral load dynamics after alemtuzumab based allogeneic stem cell transplantation.

Transplant Cell Ther 2021 May 4. Epub 2021 May 4.

Department of Haematology, UCL Cancer Institute, University College London, London, UK; Department of Haematology, University College London Hospitals NHS Foundation Trust, London, UK.

Background: Epstein-Barr virus (EBV) load monitoring post-allogeneic haematopoietic stem cell transplantation (HSCT) enables earlier detection of EBV replication and is often used as a trigger for pre-emptive therapies aiming to reduce EBV-related diseases. Our institutional strategy is to treat patients with clinical signs of EBV-related disease accompanied by a rising viral load, rather than to intervene solely based on viral load. This affords an opportunity to study the natural history of EBV replication and to assess if our strategy reduces over-treatment without compromising outcomes. Read More
