Transplant recipients are treated with immunosuppressive drugs to avoid rejection of the transplanted organ. As the medication impairs the immune response, it also increases the risk of serious infections and cancer in transplant recipients compared with the general population.
Previous studies have shown a close association between Epstein-Barr virus (EBV) and post transplant lymphoproliferative disorder (PTLD), with frequent demonstration of the virus in lesional tissues. Transplant recipients without evidence of EBV infection prior to transplantation (EBV seronegative) are at particularly high risk of developing PTLD. Other risk factors include a high viral load. As part of a preventive approach against PTLD, several transplantation units now monitor the occurrence of EBV DNAemia after transplantation. However, there is little evidence to guide this strategy; nor is there consensus concerning either the best specimen to use for EBV analysis (whole blood or plasma) or the appropriate clinical action to take if EBV DNAemia is detected.
Our aim is to estimate the incidence and clinical consequences of Epstein-Barr virus (EBV) DNAemia in whole blood and plasma in renal transplant recipients, and to determine if persistence of EBV DNAemia can predict excessive immunosuppression as indicated by the incidence of infections requiring hospitalisation, EBV driven PTLD and mortality.

| The incidence of symptomatic opportunistic infections | Defined as CMV, BK virus, Herpes simplex virus 1 and 2, Human herpes virus 6 and 7, and Varicella zoster virus. In addition, bacterial pathogens such as Legionella pneumophila, Listeria monocytogenes, Mycobacterium tuberculosis, Nocardia, all parasitic infections i.e. Pneumocystis jirovecii and fungal infections are regarded as opportunistic infections. |
