Post-transplant lymphoproliferative disease (PTLD) describes a heterogenous group of lymphoproliferative diseases, occurring as a result of uncontrolled B cell proliferation in the context of post-transplant immunosuppression. The incidence depends on the type of transplant and immunosuppression used; the median time to onset is shorter for recipients of stem cell transplants (2 months) than th...

AIMS Post-transplant lymphoproliferative disease (PTLD) is an important and serious complication in transplant patients. Recent studies have suggested that quantitative assessment of Epstein-Barr virus (EBV) infection in transplant patients might help to identify those at risk of developing PTLD. Therefore, tonsils from paediatric liver transplant recipients were studied for evidence of EBV inf...

UNLABELLED Tolerance after treatment and recovery from posttransplant lymphoproliferative disease (PTLD) have been described but little is known about the immunology. The objective of this study is to evaluate the immunity of pediatric recipients who recovered from PTLD. MATERIALS AND METHODS Pediatric recipients who recovered from PTLD after liver transplant and twice the number of recipient...

Abstract Background Epstein-Barr virus (EBV) donor seropositive/recipient seronegative (D+/R-) status is a risk factor for post-transplant lymphoproliferative disorder (PTLD) which associated with increased mortality post-lung transplant. The optimal surveillance strategy PTLD transplant stratified by EBV serostatus early diagnosis unknown. We assessed serial viral loads (VL) of and compared ou...

BACKGROUND Posttransplant lymphoproliferative disorder (PTLD) is a feared complication to organ transplantation, associated with substantial morbidity and inferior survival. Risk factors for PTLD include T cell-depleting induction therapy and primary infection or reactivation of Epstein-Barr virus. Possible associations between certain HLA types and the risk of developing PTLD have been reporte...

Epstein-Barr virus (EBV)-induced posttransplant lymphoproliferative disease (PTLD) continues to be a serious complication following transplantation. The aim of the present study was to evaluate the EBV load as a parameter for the prediction and monitoring of PTLD. The EBV load was analyzed by a quantitative competitive PCR with 417 whole-blood samples of 59 patients after allogeneic stem cell t...

This review summarizes the available evidence and outlines our approach to the prophylaxis and management of posttransplantation lymphoproliferative disorder (PTLD) in adult solid organ transplantation recipients. We attempt to reduce immunosuppression as tolerated in every patient with suspected PTLD in close cooperation with their transplantation physician. There is no evidence to guide the d...

AIM To examine the risk of late-onset post-transplant lymphoproliferative disorder (PTLD) in the presence of persisting high Epstein-Barr virus (EBV) in EBV naïve pediatric heart transplant (HT) recipients. METHODS A retrospective review of the medical records of the 145 pediatric HT recipients who had serial EBV viral load monitoring at our center was performed. We defined EBV naive patients...

BACKGROUND Management of a number of significant viral pathogens in transplant recipients remains challenging. OBJECTIVES To define an optimal antiviral approach to the management of cytomegalovirus (CMV), human herpes virus-6 (HHV-6), Epstein-Barr (EBV)-associated post-transplant lymphoproliferative disorder (PTLD), and polyoma virus-associated nephropathy in transplant recipients. METHODS...
