Background: Differences in the epidemiology of post-transplant lymphoproliferative disease (PTLD) between adult and paediatric kidney transplant recipients remain unclear. Methods: Using the Australian and New Zealand Dialysis and Transplant Registry (1963-2015), the cumulative incidences of PTLD in children (age <20 years) and adults were calculated using a competing risk of death model and compared with age-matched population-based data using standardized incidence ratios (SIRs)...

Posttransplant lymphoproliferative disorders (PTLD) represent a rare and potentially life-threatening complication after liver transplantation. Classical Hodgkin lymphoma (cHL), with an incidence of approximately 1.8-3.4% of all PTLD cases, represents a minority of PTLD, mainly presenting as a late transplant complication. The main risk factors for the development of PTLD are Epstein-Barr virus (EBV) infection and intensive immunosuppression. However, other risk factors like hepatitis C virus may, together with EBV infection, contribute to the development of PTLD...

Post-transplant lymphoproliferative disorder (PTLD) is defined as a heterogeneous group of lymphoid and plasmocytic proliferations with variable malignant potential. They often arise in immunocompromised post solid organ transplant (SOT) patients linked with Epstein-Barr virus (EBV) infection. Clinical manifestations include fever, lymphadenopathy and organ involvement. Diagnosis of PTLD requires morphopathological tissue examination. Treatment of EBV-related PTLD in SOT patients includes immunosuppressive (IS) agents' reduction, use of antiviral medication, anti-B-lymphocyte antibodies and chemotherapy for high-risk patients...

Objectives: Posttransplant lymphoproliferative disorders (PTLDs) are a heterogeneous group of hematolymphoid proliferations arising in the context of chronic immunosuppression. The common and indolent B-cell lymphomas, including extranodal marginal zone lymphomas (ENMZLs) of mucosa-associated lymphoid tissue (MALT), are excluded from the category of PTLD in the current World Health Organization classification. Methods: We report a case of Epstein-Barr virus (EBV)-positive bronchial-associated lymphoid tissue (BALT) lymphoma involving the lungs of a transplant patient...

BACKGROUND: Epstein-Barr virus (EBV) donor positive/recipient negative (D+/R-) status is a significant risk factor for posttransplant lymphoproliferative disorder (PTLD) in lung transplant. There are, however, no studies that identify the risk factors for PTLD in the EBV D+/R- lung transplant population to guide the decision to proceed with an EBV-positive donor. METHODS: This was a retrospective cohort study of adults listed in the Scientific Registry of Transplant Recipients between May 5, 2005, and August 31, 2016...

Conventional therapeutic approaches to post-transplant lymphoproliferative disorder (PTLD) occurring after solid-organ transplantation have shown only limited success in achieving durable response. Key factors driving the pathogenesis of PTLD include Epstein-Barr virus (EBV) reactivation and impaired immune surveillance due to prolonged immune suppression. Thus, EBV-specific cytotoxic T lymphocytes (EBV-CTLs) have emerged as an alternative therapeutic approach for the treatment of EBV-associated PTLD by enhancing EBV-specific immunity...

BACKGROUND: Epstein-Barr virus (EBV) was the first human virus identified to express microRNA (miRNA). To date, 44 mature miRNAs are encoded for within the EBV genome. EBV miRNAs have not been profiled in paediatric renal transplant recipients. In this study, we investigated circulating EBV miRNA profiles as novel biomarkers in paediatric renal transplant patients. METHODS: Forty-two microRNAs encoded within 2 EBV open reading frames (BART and BHRF) were examined in renal transplant recipients who resolved EBV infection (REI) or maintained chronic high viral loads (CHL), and in non-transplant patients with acute infectious mononucleosis (IM)...

Post-transplantation lymphoproliferative disease (PTLD) is a serious complication following hematopoietic stem cell transplantation (HSCT). The majority of the cases develop during the first year after the transplantation and are associated with reactivation of the Epstein-Barr virus (EBV); the EBV-induced lymphoproliferation usually includes donor-derived B cells. We herein describe the case of a 28-year-old female patient who developed EBV-negative PTLD, namely diffuse large B-cell lymphoma (DLBCL), 6 months after receiving a haploidentical HSCT from her father...

Posttransplant lymphoproliferative disorders (PTLD) represent an immunosuppression-related lymphoid or plasmacytic proliferation that occur in the setting of solid organ transplant or allogeneic hematopoietic stem cell transplantation (HSCT). PTLD is a devastating consequence of HSCT and solid organ transplantation with a high morbidity and mortality. Most commonly, PTLD is related to Epstein-Barr virus (EBV) infection, but an increasing number of non-EBV-related cases are occurring. Initial therapy involves withdrawal of immunosuppression with or without antibody or cytotoxic chemotherapy...

Epstein-Barr virus (EBV)-induced post-transplant lymphoproliferative disorder (PTLD) occurs frequently when rabbit antithymocyte globulin (ATG) is used in hematopoietic cell transplant (HCT) conditioning. We retrospectively studied 554 patients undergoing ATG-conditioned myeloablative HCT. Strategies used to minimize mortality due to PTLD were either therapy of biopsy-diagnosed PTLD in the absence of EBV DNAemia monitoring (n = 266) or prompt therapy of presumed PTLD (based on clinical/radiologic signs and high EBV DNAemia, in the setting of weekly EBV DNAemia monitoring) (n = 199)...

BACKGROUND: There is a lack of clinical information regarding the usefulness of plasma Epstein-Barr virus (EBV) DNA load kinetics analyses in the management of EBV infections in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients. Namely, it remains unknown whether this type of analysis can help physicians to anticipate the development of high-level EBV DNAemia episodes requiring rituximab treatment or predict the risk of recurrent EBV DNAemia or post-transplant lymphoproliferative disorders (PTLDs)...

Post-transplant lymphoproliferative disorders (PTLDs) are a heterogeneous group of lymphoid neoplasms associated with immunosuppression following transplantation. Among PTLDs, monomorphic PTLD (m-PTLD) is the largest category; however, its characteristics and survival outcome are not fully understood because of low incidence. This study enrolled 30 adult patients with m-PTLD after kidney-transplantation (KT, n = 17) and hematopoietic stem cell transplantation (HSCT, n = 13) from January 1998 to December 2014...

Post-transplantation lympho-proliferative disorder (PTLD) pathogenesis is related to EBV infection. Mismatch with the donor (EBV D+/R-) is the main risk factor for both early PTLD (< 1 year post transplantation) and late (> 1 year). In these at-risk patients, the role of antiviral prophylaxis for preventing PTLD remains controversial. We analysed the impact of antiviral drugs given to prevent CMV disease in a mono-centric retrospective cohort of 73 adult kidney or kidney-pancreas EBV seronegative recipients, transplanted between 01/01/2000 and 01/01/2016...

In solid organ transplant recipients, Epstein-Barr virus (EBV) can cause active central nervous system (CNS) infection or malignant transformation of latently infected cells in the CNS, known as post-transplant lymphoproliferative disease (PTLD). Reduction of T-cell immunosuppression is the cornerstone of management. The role of antivirals with in-vitro activity against herpesviruses in EBV-related CNS syndromes is controversial, as they have no effect on latent virus. We report an unusual case of relapsing EBV encephalitis in a donor-positive, EBV-negative renal transplant recipient, with response to valganciclovir...

Primary central nervous system post-transplant lymphoproliferative disorder (PCNS-PTLD) is a rare complication with inferior survival outcomes in solid organ transplant patients. It represents approximately 7-15% of all PTLD patients. Because of the rarity of this disease, the diagnosis of PCNS-PTLD is often challenging, and the optimal therapy has not been established. We report a case of a renal transplant patient who initially presented with acute altered neurological function, an enhancing mass lesion of the brain on magnetic resonance imaging (MRI), and nonspecific reactive histopathological changes on brain biopsy...

Epstein-Barr virus (EBV) poses a significant threat to patient and graft survival post-transplant. We hypothesized that recipients who shed EBV at transplant had less immunologic control of the virus and hence were more likely to have active EBV infection and disease post-transplant. To test this hypothesis, we conducted a 5-year prospective study in primary solid organ transplant recipients. We measured EBV DNA in oral washes and blood samples by quantitative PCR before transplant and periodically thereafter for up to 4 years...
