These updated guidelines from the American Society of Transplantation Infectious Diseases Community of Practice review the diagnosis, management, and prevention of post-transplant lymphoproliferative disorders (PTLD) and other Epstein-Barr virus (EBV) syndromes after solid organ transplantation.

PTLD is Post Transplant Lympho proliferative Disease

PTLD are a heterogeneous spectrum of predominantly B-cell disorders, often extra-nodal, with complex distinct pathogeneses and variable clinical presentations determined by pathologic subtype.

Late onset PTLD increasing

Recent epidemiologic studies report a decrease in early EBV-positive (+) PTLD and an increase in late EBV-negative (−) PTLD.

EBV- to EBV+ important risk factor

Pre-transplant EBV-seronegativity and primary EBV infection, often from donor-transmitted infection, are an important risk factors for EBV syndromes and early EBV + PTLD.

Pre emptive strategies for EBV- patients

Low-quality evidence supports pre emptive prevention strategies for early EBV + PTLD in EBV-seronegative recipients that involve EBV DNA measurement in peripheral blood using assays requiring further result harmonization, combined with interventions to lower viral load. Reduction in immunosuppression (RIS) is the best validated intervention.

WHO pathology classification of a tissue biopsy remains the gold standard for PTLD diagnosis; optimal staging procedures are uncertain.

Treatments for PTLD

Treatment of CD20+ PTLD with the response-dependent sequential use of:
~ RIS,
~ rituximab, and
~cytotoxic chemotherapy is recommended.

Evidence gaps requiring future research and alternate treatment strategies including immunotherapy are highlighted.
