Post-transplant lymphoproliferative disorder (PTLD) is one of the most common neoplasms seen after solid organ and hematopoietic stem cell transplantation, and is associated with significant morbidity and mortality. The pathogenesis is related to post-transplant immunosuppression and EBV infection. Prevention of PTLD depends upon judicious use of immunosuppression and serial EBV monitoring. Preemptive therapy consists of reduction of immunosuppression, antiviral medications, and single-agent rituximab. There are no randomized phase III trials on PTLD treatment, so current management guidelines are largely based on recent phase II trials, single-institution retrospective studies, and expert opinion...

INTRODUCTION: Here we present a case of atraumatic splenic rupture secondary to varicella infection requiring emergency splenectomy. The presentation was as would be expected for epstein barr virus (EBV) related splenic injury, which is well documented in the literature. Dermatological findings however suggested varicella zoster, and viral serology subsequently confirmed the diagnosis. PRESENTATION OF CASE: A young Romanian male presented to the emergency department with peritonism without preceding trauma...

Background: Epstein-Barr virus (EBV) has been found to cause infectious mononucleosis multiple times, but has been associated rarely with EBV encephalitis. Also, whenever it is diagnosed, it is always treated symptomatically. Case report: A case of confirmed EBV encephalitis is presented, which was treated with antiviral therapy resulting in complete clearance of the virus in cerebrospinal fluid and minimal neurologic symptoms after hospital discharge. Conclusion: The Infectious Diseases Society of America guidelines state that intravenous acyclovir is not recommended for EBV-related encephalitis...

Epstein-Barr virus (EBV) DNA analysis has been shown to be useful for early detection, prognostication, and monitoring of treatment response of nasopharyngeal carcinoma (NPC), and the recent literature provides growing evidence of the clinical utility of EBV DNA testing, particularly to inform treatment decisions for NPC patients. Despite the fact that NPC is a rare disease, the NRG Oncology cooperative group has successfully activated a phase 2/3 randomized clinical trial for NPC with international partners and in that process has discovered that the development of a harmonized EBV DNA test is absolutely critical for integration into clinical trials and for future deployment in clinical and central laboratories...

Epstein Barr virus (EBV) is well known to cause different types of malignancies. In immunocompromised patients, such as those infected with human immunodeficiency virus (HIV), there is a higher likelihood of EBV related malignant transformation. Diagnosis of EBV related malignancies may be difficult and sometimes requires clinical and pathological correlation. It is very rare to have more than one type of EBV related malignancy in a single patient. Until now, there are no specific guidelines for treatment of EBV related malignancies and lymphoproliferative disorders (LPD)...

Posttransplant lymphoproliferative disease (PTLD) is a potentially fatal complication after (solid organ) transplantation, which is highly associated with Epstein-Barr virus (EBV). The EBV-specific cytotoxic T cell response that is essential in controlling the virus in healthy individuals is suppressed in transplant recipients using immunosuppressive drugs. A primary EBV infection in EBV-seronegative patients receiving an EBV-seropositive donor organ or a reactivation in those who are already latently infected pretransplantation can lead to uninhibited growth of EBV-infected B cells and subsequently to PTLD...

Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) of the elderly is a provisional entity included in the 2008 WHO classification of lymphoid neoplasms. It is a disease typically seen in the elderly and thought to be associated with chronic EBV infection and severe immunosuppression with a component of immunosenescence. Recent research, however, has suggested that EBV-positive DLBCL can be seen in younger, immunocompetent patients. The diagnosis of EBV-positive DLBCL of the elderly is made through a careful pathological evaluation...

Post-transplant lymphoproliferative disorders (PTLD) are a serious complication after solid organ or allogeneic hematopoietic stem cell transplantation and include a range of diseases from benign proliferations to malignant lymphomas. Risk factors for developing PTLD include Epstein-Barr virus (EBV) infection, recipient age, transplanted organ, type of immunosuppression, and genetics. Uncontrolled proliferation of EBV-infected B cells is implicated in EBV-positive PTLD, whereas the pathogenesis of EBV-negative PTLD may be similar to non-Hodgkin's lymphoma in the general population...

Epstein-Barr virus-encoded latent membrane protein-1 (LMP1) plays a fundamental role in the malignant transformation of nasopharyngeal carcinoma (NPC), although the mechanism is not well understood. Here, we showed that Limb-bud and Heart (LBH) is considerably downregulated in patient NPC tissues. The expression of LBH in biopsies of 40 consecutive NPC patients devoid of initial distant metastasis and treated according to consistent guidelines was also analyzed, and we found the LBH expression level was correlated with some of clinicopathological features, disease-specific survival (DSS), distant metastasis-free survival (DMFS)...
