Abstract
Nephrologists may encounter many systemic problems in their patients, including involvement of the neurological system and the development of seizures. Seizures are defined as abnormal neurological functions that cause overstimulation of neurons in the cerebral cortex or limbic system. Seizures may be focal or generalized depending on their origin and may have tonic, clonic, tonic-clonic or myoclonic character depending on the level of involvement of the motor movements. Patients with kidney disease may develop seizures due to etiologies seen in the general population (such as intracranial bleeding, cerebrovascular events, tumors, infections and intoxications) or due to kidney-related etiologies (such as uremic encephalopathy, dialysis disequilibrium syndrome and hyponatremia). Management of seizures in kidney patients is challenging for proper determination of the type and dosage of antiepileptic drugs due to varying renal clearances. This review covers the major causes of new-onset seizures in patients with acute kidney injury, electrolyte imbalances, chronic kidney disease, dialysis, renal transplantation or hypertension, and the available management approaches.

Abstract
Post-transplant lymphoproliferative disease (PTLD) is a well-recognized complication after transplant. This study aimed to develop and validate a risk score to predict PTLD among solid organ transplant (SOT) recipients. Poisson regression identified predictors of PTLD with the best fitting model selected for the risk score. The derivation cohort consisted of 2546 SOT recipients transpanted at Rigshospitalet, Copenhagen between 2004 and 2019; 57 developed PTLD. Predictors of PTLD were high-risk pre-transplant Epstein–Barr Virus (EBV), IgG donor/recipient serostatus, and current positive plasma EBV DNA, abnormal hemoglobin and C-reactive protein levels. Individuals in the high-risk group had almost 7 times higher incidence of PTLD (incidence rate ratio (IRR) 6.75; 95% CI: 4.00–11.41) compared to the low-risk group. In the validation cohort of 1611 SOT recipients from the University Hospital of Zürich, 24 developed PTLD. A similar 7 times higher risk of PTLD was observed in the high-risk group compared to the low-risk group (IRR 7.17, 95% CI: 3.05–16.82). The discriminatory ability was also similar in derivation (Harrell’s C-statistic of 0.82 95% CI (0.76–0.88) and validation (0.82, 95% CI:0.72–0.92) cohorts. The risk score had a good discriminatory ability in both cohorts and helped to identify patients with higher risk of developing PTLD.

Abstract
Post-transplant lymphoproliferative disorder (PTLD) comprises a broad spectrum of diseases and is a rare but serious complication of solid organ transplantation. We report the case of a 45-year-old simultaneous pancreas and kidney (SPK) transplant recipient with diffuse, early-onset PTLD, manifesting as jejunal perforation at 6 months after transplantation. The patient underwent urgent small bowel resection of the affected portion of jejunum. The surgical pathology report was significant for diffuse large B-cell lymphoma. Subsequently, the patient underwent a full workup, including upper and lower endoscopy and whole-body positron emission tomography that revealed involvement of the axial skeleton and multiple abdominal organs with sparing of the grafts. He was treated with rituximab and intrathecal methotrexate for central nervous system prophylaxis. The patient experienced complete resolution of disease by positron emission tomography 8 months after initial presentation. We found no previous report in the literature of intestinal perforation as the initial presentation of PTLD in SPK transplant recipients.

Abstract
Post-transplantation lymphoproliferative disorder (PTLD) is uncommon following solid organ transplantation. We present a case of PTLD presenting as hematochezia and abdominal pain in a 66-year-old man, who had undergone bilateral lung transplantation with alemtuzumab induction 7 months prior to presentation. The transplant serologic status was "high-risk" for the presence of both Epstein-Barr virus (EBV) serologies in the donor and negative serologies in the recipient. Biopsies taken during colonoscopy stained strongly positive for EBV-encoded RNA. Mediastinal lymph node biopsies also showed atypical, EBV-positive lymphohistiocytic infiltration with focal necrosis. The patient's hospital course was complicated by treatment side effects, most notably bowel perforation following rituximab. In this case report the topic of PTLD is reviewed and consideration is given to whether alemtuzumab induction may have contributed to the patient's development of PTLD.

Abstract
BACKGROUND Solid organ transplantation is associated with a higher risk of Epstein-Barr virus (EBV)-related lymphoproliferative disease due to immunosuppressive regimen. Little evidence is currently available on post-transplant lymphoproliferative disorders (PTLDs) in the lung transplant (LuTx) setting, particularly in cystic fibrosis (CF) recipients. METHODS We retrospectively analyzed all the cases of PTLDs that occurred in our LuTx center between January 2015 and December 2017. We reviewed clinical and radiologic data, donor and recipient EBV serostatus, immunosuppressive therapy, histologic data, and follow-up of these patients. RESULTS A total of 77 LuTxs were performed at our center in the study period; 39 (50.6%) patients had CF; 4 developed EBV-related PTLDs. They were all young (17-26 years) CF patients with high serum EBV DNA load. Disease onset was within the first 3 months after LuTx. In 3 cases presentation was associated with fever and infection-like symptoms, whereas in 1 case radiologic suspicion arose unexpectedly from a CT scan performed for different clinical reasons. Diagnosis was reached through lung biopsy in all cases. All patients received rituximab, cyclophosphamide, doxorubicin hydrochloride (hydroxydaunomycin), vincristine sulfate (Oncovin), and prednisone with variable response and complications. CONCLUSION In our experience, the early development of EBV-related PTLD was a highly aggressive, life-threatening condition, which exclusively affected young CF patients in the early post-transplant period. The rate of this complication was relatively high in our population. Diagnosis with lung biopsy is crucial in all suspected cases and regular monitoring of EBV DNA levels is of utmost importance given the high correlation with PTLDs in patients at increased risk.

Abstract
OBJECTIVES Posttransplant lymphoproliferative disorder is a known complication of solid-organ transplant. The use of depleting induction agents has demonstrated varying associations with incidence of posttransplant lymphoproliferative disorder. Alemtuzumab, a depleting induction agent for kidney transplant patients, has shown promising results in reducing the risk of acute rejection and graft loss in the first year. Its unique mechanism of depleting both T-cell and B-cell populations may be beneficial in preventing the occurrence of posttransplant lymphoproliferative disorder. MATERIALS AND METHODS We examined the known risk factors for posttransplant lymphoproliferative disorder in the setting of alemtuzumab induction to determine whether incidence increases with this induction agent. We reviewed medical records of all alemtuzumab-induced kidney transplants from March 2006 to November 2015. RESULTS Of the 675 transplant patients who received alemtuzumab induction, 10 developed posttransplant lymphoproliferative disorder, with a cumulative incidence rate of 1.5%. All diagnosed patients had several known risk factors associated with posttransplant lymphoproliferative disorder: 7 with advanced age over 60 years, 5 being cytomegalovirus-negative recipients, and all 10 donor kidneys being male patients and Epstein-Barr virus positive before transplant. CONCLUSIONS The incidence rate seen in our patient population was within the range of the average in the United States but far lower than the incidence rates associated with other induction agents. Alemtuzumab is associated with a lower cumulative incidence rate of posttransplant lymphoproliferative disorder compared with published reports of other induction treatments.

Abstract
The prevention, diagnosis, and management of infectious disease in transplantation are major contributors to improved outcomes in organ transplantation. The risk of serious infections in organ recipients is determined by interactions between the patient's epidemiological exposures and net state of immune suppression. In organ recipients, there is a significant incidence of drug toxicity and a propensity for drug interactions with immunosuppressive agents used to maintain graft function. Thus, every effort must be made to establish specific microbiologic diagnoses to optimize therapy. A timeline can be created to develop a differential diagnosis of infection in transplantation based on common patterns of infectious exposures, immunosuppressive management, and antimicrobial prophylaxis. Application of quantitative molecular microbial assays and advanced antimicrobial therapies have advanced care. Pathogen-specific immunity, genetic polymorphisms in immune responses, and dynamic interactions between the microbiome and the risk of infection are beginning to be explored. The role of infection in the stimulation of alloimmune responses awaits further definition. Major hurdles include the shifting worldwide epidemiology of infections, increasing antimicrobial resistance, suboptimal assays for the microbiologic screening of organ donors, and virus-associated malignancies. Transplant infectious disease remains a key to the clinical and scientific investigation of organ transplantation.

Abstract
The diagnosis of lymphoproliferative disorders associated with immunodeficiency can be challenging because many of these conditions have overlapping clinical and pathologic features and share similarities with their counterparts in the immunocompetent setting. There are subtle but important differences between these conditions that are important to recognize for prognostic and therapeutic purposes. This article provides a clinicopathologic update on how understanding of these B-cell lymphoproliferations in immunodeficiency has evolved over the past decade.

Abstract
BACKGROUND Epstein-Barr virus and Cytomegalovirus reactivations frequently occur after allogeneic stem cell transplantation (SCT). METHODS Here we investigated the role of immune cell reconstitution in the onset and subsequent severity of EBV- and CMV-reactivation. To this end, 116 patients were prospectively sampled for absolute T cell (CD4 and CD8), B-cell (CD19) and NK-cell (CD16 and CD56) numbers weekly post-SCT during the first 3 months and thereafter monthly until 6 months post-SCT. Viral load was monitored in parallel. RESULTS In contrast to the general belief, we found that early T-cell reconstitution does not play a role in the onset of viral reactivation. CMV reactivation in the first 7 weeks after SCT however resulted in higher absolute CD8(+) T-cell numbers 6 months post-SCT in patients with high-level reactivation, many of which were CMV-specific. Interestingly, rapid reconstitution of CD4(+) T-cells, as well as NK cells and the presence of donor KIR3DL1, are associated with the absence of CMV-reactivation after SCT, suggestive of a protective role of these cells. In contrast, EBV-reactivations were not affected in any way by the level of immune reconstitution after SCT. CONCLUSION In conclusion, these data suggest that CD4(+) T-cells and NK cells, rather than CD8(+) T-cells, are associated with protection against CMV-reactivation.

Abstract
BACKGROUND Epstein-Barr virus (EBV)-seronegative renal transplant recipients are at risk of post-transplant lymphoproliferative disorder (PTLD). We compared primary EBV infection, seroconversion, and PTLD in EBV-seronegative patients who received renal allograft from seropositive or seronegative donors (D+/R- and D-/R-, respectively). METHODS We prospectively followed 25 D+/R- and 8 D-/R- recipients. We followed patients from January 1999 to June 2009 with clinical visits, monthly EBV polymerase chain reaction tests, and serologic tests for a period of 1 year after kidney transplantation and on an individual basis thereafter. RESULTS Three patients (9%) developed PTLD including 2 early-onset (<12 months) and 1 late-onset (>12 months) disease. In D+/R- and D-/R- patients, the frequencies of PTLD (8% vs. 12.5%, P = 0.7), EBV seroconversion (64% vs. 50%, P = 0.4), and EBV viremia (40% vs. 25%, P = 0.6) were not significantly different. Clinical, serologic, and virologic surveillance as well as reduction in immunosuppression after evidence of primary EBV infection resulted in a PTLD rate of 9%, despite a seroconversion rate of 60.6%. Rate of graft loss after reduction in immunosuppression was 10% (2 of 20), which was not significantly different from 13 patients without EBV seroconversion (no graft loss, P = 0.5). Rates of viremia, seroconversion, and PTLD in D+/R- and D-/R- patients appear to be similar. CONCLUSIONS The incidence of PTLD in renal transplants ranges from 0.5% to 2.9%. Our data show a significantly higher rate in EBV-seronegative renal allograft recipients, suggesting the need for close surveillance. Our data also suggest that donors for EBV-seronegative recipients may be accepted irrespective of positive or negative serostatus, with ongoing surveillance important in either circumstance.

Abstract
EBV-associated PTLD is increasingly recognized as an important cause of morbidity and mortality in both solid organ and hematopoietic stem cell transplant recipients. Mortality rates due to PTLD and virus-induced HLH are reported to be quite high. We report a case of EBV-associated PTLD and HLH in a child after liver transplantation who was successfully managed due to timely intervention. This case highlights that measurement of EBV load by quantitative polymerase chain reaction assays is an important aid in the surveillance and diagnosis of PTLD and early detection of EBV-induced PTLD, and aggressive treatment with rituximab is a key to survival in patients who have undergone liver transplantation.

Post-transplant lymphoproliferative disease (PTLD): risk factors, diagnosis, and current treatment strategies. Curr Hematol Malig Rep 2014; 8:173-83.

Abstract
Post-transplant lymphoproliferative diseases (PTLD) are heterogeneous lymphoid disorders ranging from indolent polyclonal proliferations to aggressive lymphomas that complicate solid organ or hematopoietic transplantation. Risk factors for PTLD include viral infections, degree of immunosuppression, recipient age and race, allograft type, and host genetic variations. Clinically, extra-nodal disease is common including 10-15 % presenting with central nervous system (CNS) disease. Most PTLD cases are B cell (5-10 % T/NK cell or Hodgkin lymphoma), while over one-third are EBV-negative. World Health Organization (WHO) diagnostic categories are: early lesions, polymorphic, and monomorphic PTLD; although in practice, a clear separation is not always possible. Therapeutically, reduction in immunosuppression remains a mainstay, and recent data has documented the importance of rituximab +/- combination chemotherapy. Therapy for primary CNS PTLD should be managed according to immunocompetent CNS paradigms. Finally, novel treatment strategies for PTLD have emerged, including adoptive immunotherapy and rational targeted therapeutics (e.g., anti-CD30 based therapy and downstream signaling pathways of latent membrane protein-2A).

Abstract
Immune suppression is a risk factor for malignant lymphoma development. Progress in medical science has increased the numbers of immunosuppressed patients due to organ transplantations or successful treatment of autoimmune diseases. Different forms of immune suppression and the respective lymphoma entities are discussed in this article. Another issue treated are gray zone lymphomas between Hodgkin's lymphoma and diffuse large B cell lymphoma. This category not only represents a diagnostic challenge but also represents more a true biological continuum.

Abstract
Posttransplant lymphoproliferative disorder (PTLD) is a potentially fatal disease that arises in 2%-10% of solid organ and hematopoietic stem cell transplants and is most frequently of B-cell origin. This very heterogeneous disorder ranges from benign lymphoproliferations to malignant lymphomas, and despite the clear association with Epstein-Barr Virus (EBV) infection, its etiology is still obscure. Although a number of risk factors have been identified (EBV serostatus, graft type, and immunosuppressive regimen), it is currently not possible to predict which transplant patient will eventually develop PTLD. Genetic studies have linked translocations (involving C-MYC, IGH, BCL-2), various copy number variations, DNA mutations (PIM1, PAX5, C-MYC, RhoH/TTF), and polymorphisms in both the host (IFN-gamma, IL-10, TGF-beta, HLA) and the EBV genome to B-cell PTLD development. Furthermore, the tumor microenvironment seems to play an important role in the course of disease representing a local niche that can allow antitumor immune responses even in an immunocompromised host. Taken together, B-cell PTLD pathogenesis is very complex due to the interplay of many different (patient-dependent) factors and requires thorough molecular analysis for the development of novel tailored therapies. This review aims at giving a global overview of the currently known parameters that contribute to the development of B-cell PTLD.

Abstract
Intestinal and multivisceral transplantation has evolved from an experimental procedure to the treatment of choice for patients with irreversible intestinal failure and serious complications related to long-term parenteral nutrition. Increased numbers of transplant recipients and improved survival rates have led to an increased prevalence of this patient population in intensive care units. Management of intestinal and multivisceral transplant recipients is uniquely challenging because of complications arising from the high incidence of transplant rejection and its treatment. Long-term comorbidities, such as diabetes, hypertension, chronic kidney failure, and neurological sequelae, also develop in this patient population as survival improves. This article is intended for intensivists who provide care to critically ill recipients of intestinal and multivisceral transplants. As perioperative care of intestinal/multivisceral transplant recipients has been described elsewhere, this review focuses on common nonsurgical complications with which one should be familiar in order to provide optimal care. The article is both a review of the current literature on multivisceral and isolated intestinal transplantation as well as a reflection of our own experience at the University of Miami.

Abstract
The herpes viruses are responsible for a wide range of diseases in patients following transplant, resulting from direct viral effects and indirect effects, including tumor promotion. Effective treatments and prophylaxis exist for the neurotropic herpes viruses HSV-1, HSV-2, varicella zoster virus, and possibly HHV-6. Antivirals seem to be less effective at prevention of the tumor-promoting effects of Epstein-Barr virus and HHV-8. Reduction in immunosuppression is the cornerstone to treatment of many diseases associated with herpes virus infections.

Abstract
Post-transplant lymphoproliferative disorders (PTLDs) are serious, life-threatening complications of solid-organ transplantation (SOT) and bone marrow transplantation leading to a high mortality (30-60%). PTLD represents a heterogeneous group of lymphoproliferative diseases. They become clinically relevant because of the expansion of transplantation medicine together with the development of potent immunosuppressive drugs. Although the diagnostic morphological criteria of different forms of PTLD are commonly known, rapid and correct diagnosis is not always easy. Because of the limited number of clinical trials, a consensus is lacking on the optimal treatment of PTLD. This review focuses on incidence, risk factors, clinical picture of the disease and diagnostic tools including histopathology relating to the new classification introduced in 2008 by the World Health Organisation (WHO) and treatment of PTLD.

Abstract
A joint working group established by the Haemato-oncology subgroup of the British Committee for Standards in Haematology (BCSH) and the British Transplantation Society (BTS) has reviewed the available literature and made recommendations for the diagnosis and management of post-transplant lymphoproliferative disorder (PTLD) in adult recipients of solid organ transplants. This review details the risk factors predisposing to development, initial features and diagnosis. It is important that the risk of developing PTLD is considered when using post transplant immunosuppression and that the appropriate investigations are carried out when there are suspicions of the diagnosis. These must include tissue for histology and computed tomography scan to assess the extent of disease. These recommendations have been made primarily for adult patients, there have been some comments made with regard to paediatric practice.

Abstract
BACKGROUND Post-transplantation lymphoproliferative disorder (PTLD) is a major cause of morbidity and mortality after pediatric heart transplantation. METHODS Heart transplant recipients at The Hospital for Sick Children, Toronto, from 1990 to May 2008, were reviewed. Competing risk hazard analysis was used to model the natural history of the disease. Patients were matched for gender and duration of follow-up to identify potential covariates associated with increased risk of PTLD. RESULTS A total of 173 heart transplant recipients (42% <1 year old) were reviewed. Twenty-three developed PTLD at a median of 4 years post-transplantation. After transplantation, PTLD affected 9%, 15% and 28% at 3, 5 and 10 years, respectively. Freedom from death or PTLD recurrence was 72%, 58% and 50% at 1, 3 and 5 years, respectively, after PTLD diagnosis. Higher maximum Epstein-Barr viral (EBV) load (hazard ratio [HR]: 2.6, p = 0.004) and longer duration of induction therapy (HR: 1.7, p = 0.02) were associated with increased risks of PTLD. Higher cumulative cyclosporine doses over the first year post-transplantation were associated with increased risks of PTLD (HR: 1.2 per 1 mg/kg/day equivalent, p = 0.03), but higher tacrolimus doses were not (p = 0.38). Patients on cyclosporine at 6 months post-transplantation were at higher risk of PTLD than those on tacrolimus (HR: 5.2, p = 0.003). The use of anti-viral prophylaxis in patients with high EBV load may provide some protection (HR: 7.6 vs 15.4 with no anti-viral, p = 0.02). CONCLUSIONS PTLD is a major concern in pediatric heart transplant recipients and is associated with high morbidity/mortality. Exposure to EBV and higher intensity of immunosuppression seems to be associated with increased risk.

Abstract
Post-transplant lymphoproliferative disorders (PTLD) are a life-threatening complication of solid organ transplantation or, more rarely, hematopoietic stem cell transplantation. The majority of PTLD is of B-cell origin and associated with Epstein–Barr virus (EBV) infection. PTLD generally display involvement of extranodal sites, aggressive histology and aggressive clinical behavior. The molecular pathogenesis of PTLD involves infection by oncogenic viruses, namely EBV, as well as genetic or epigenetic alterations of several cellular genes. At variance with lymphoma arising in immunocompetent hosts, whose genome is relatively stable, a fraction of PTLD are characterized by microsatellite instability as a consequence of defects in the DNA mismatch repair mechanism. Apart from microsatellite instability, molecular alterations of cellular genes recognized in PTLD include alterations of cMYC, BCL6, TP53, DNA hypermethylation, and aberrant somatic hypermutation of protooncogenes. The occurrence of IGV mutations in the overwhelming majority of PTLD documents that malignant transformation targets germinal centre (GC) B-cells and their descendants both in EBV–positive and EBV–negative cases. Analysis of phenotypic markers of B-cell histogenesis, namely BCL6, MUM1 and CD138, allows further distinction of PTLD histogenetic categories. PTLD expressing the BCL6+/MUM1+/-/CD138− profile reflect B-cells actively experiencing the GC reaction, and comprise diffuse large B-cell lymphoma (DLBCL) centroblastic and Burkitt lymphoma. PTLD expressing the BCL6−/MUM1+/CD138− phenotype putatively derive from B-cells that have concluded the GC reaction, and comprise the majority of polymorphic PTLD and a fraction of DLBCL immunoblastic. A third group of PTLD is reminiscent of post-GC and preterminally differentiated B-cells that show the BCL6−/MUM1+/CD138+ phenotype, and are morphologically represented by either polymorphic PTLD or DLBCL immunoblastic.

Abstract
Posttransplantation lymphoproliferative disorders (PTLDs) are a heterogeneous group of diseases that represent uncommon complications of transplantation and can lead to significant morbidity and mortality. PTLD is most prevalent during the first year following transplantation and occurs most frequently in multiorgan transplant recipients, followed by bowel, heart-lung, and lung recipients. It may involve any of the organ systems, with disease manifestation and the anatomic pattern of organ involvement being highly dependent on the type of transplantation. The current classification system includes four subtypes that have different prognoses requiring different treatment strategies. Tissue sampling is necessary for diagnosis and further subcategorization. The majority of cases are characterized by B-cell proliferation and are related to infection from Epstein-Barr virus. Knowledge of the distribution and radiologic features of PTLD allows the radiologist to play a pivotal role in making an early diagnosis and in guiding biopsy.

Abstract
Post-transplant lymphoproliferative disorder (PTLD) is a serious complication after solid-organ transplantation. We report a lung transplant recipient presenting with lower limb weakness as a result of extradural cord compression from PTLD. Diagnosis was made by laminectomy of T-3 with partial removal of the epidural mass. Further treatment consisted of chemoradiotherapy. The patient recovered completely. To our knowledge, this is the first reported case of PTLD presenting with signs and symptoms of spinal cord compression. The differential diagnosis of spinal cord compression in a patient who has had a transplant should include primary presentation of PTLD.

Abstract
PTLD is a severe complication in transplant recipients. Detection of increased EBV load in the peripheral blood acts as a surrogate marker for increased risk of PTLD development. We analyzed the time course of the disease, its severity, the organs involved, and mortality rates in our institutional experience of pediatric heart transplantation. This paper identifies risk factors for PTLD and describes the different ways of diagnosing and treating the disease. PTLD was screened for in 146 pediatric heart transplant patients using a retrospective analysis in patients who received transplantation before 1998. Prospective determination was performed in 72/146 patients transplanted after 1998 within the post-transplant follow-up. The occurrence of PTLD with all interventions, including tapering of immunosuppression, surgery, viral monitoring, and antiviral interventions, was recorded. PTLD was diagnosed in 12/147 (8.2%) children at a mean age of 7.2 +/- 3.3 yr after a mean post-transplant period of 3.2 +/- 2.2 yr. PTLD manifested in: lymph nodes (n = 4), intestine (n = 3), tonsils and adenoids (n = 2), eye (n = 2), and lung (n = 1). It was diagnosed in 7/12 as a monomorphic B-cell lymphoma and in four patients as a monomorphic Burkitt lymphoma, a polymorphic B-cell lymphoma, a T-cell rich or angiocentric lymphoma (Liebow) and as reactive plasmacytic hyperplasia (early lesion), respectively. Histology was not possible in one patient with ocular manifestation. EBV association was 83%. Risk factors in the comparison with patients without PTLD were age at time of Tx, primary EBV infection after Tx, use of Azathioprine and >or=3 doses of ATG. CMV mismatch and CMV infection, rejection episodes and steroids were not risk factors. Despite reduction of immunosuppression, treatment consisted of surgical procedures to remove tumor masses (n = 6), Rituximab (n = 5), polychemotherapy (n = 3), antiviral (n = 1) and autologous T-cell therapy (n = 1). All patients demonstrated full remission without death related to PTLD or treatment at 3.9 (1.3-6.2) yr median follow-up time. The manifestation of PTLD in pediatric heart transplant recipients is associated with EBV infection and is predominantly in the form of a B-cell lymphoma. A tight and specific follow-up including early assessment of immunity status and specific therapeutic intervention to improve cellular immunity is warranted and may contribute to a significant reduction of PTLD-related morbidity and mortality.

Abstract
After infection with the Epstein - Barr virus, a common gammaherpes virus which infects and persists in the B cells, an equilibrium is established in which newly infected and differentiating B cells are controlled by cytotoxic T cell (CTL) responses. Disturbance of this equilibrium, which can occur in immunocompromised situations, can lead to uncontrolled lymphoproliferation and subsequent development of non-Hodgkin Lymphomas (NHL). Here, we review the role of immunesurveillance of EBV-infected B cells and two situations where immunesurveillance is altered because of immunodeficiencies, transplantation recipients and HIV infection, which can lead to EBV-mediated NHL. In transplant recipients, immunosuppression prior and during transplantation can lead to lack of immunesurveillance and results in proliferation of infected B cells, which would normally be controlled by CTL responses. Interestingly, in HIV infection both deregulation of the normal B cell biology and a reduction in immunity play a role in developing NHL. Therefore, the nature of EBV infection in HIV-positive subjects is very different from that in transplanted individuals, in whom (re-)appearance of EBV-specific CD8(+) T cells - either by a decrease in immune suppression or infusion of donor lymphocytes - immediately leads to a decrease in EBV load.

Abstract
Viral infections remain a significant cause of morbidity and mortality following renal transplantation. Although cytomegalovirus is the most common opportunistic pathogen seen in transplant recipients, numerous other viruses have also affected outcomes. In some cases, preventive measures such as pretransplant screening, prophylactic antiviral therapy, or post transplant viral monitoring may limit the impact of these infections. Recent advances in laboratory monitoring and antiviral therapy have improved outcomes. This review will summarize the major viral infections seen following transplant and discuss strategies for prevention and management of these potential pathogens.

Abstract
BACKGROUND Post-transplant lymphoproliferative disease (PTLD) is a severe complication in transplant recipients. Detection of increased Epstein-Barr viral (EBV) load in the peripheral blood acts as a surrogate marker for increased risk of PTLD development. We prospectively monitored EBV load, immunosuppression and PTLD in pediatric heart transplant (HTx) patients to determine risk factors for an increased EBV load and risk of PTLD. METHODS Forty-one pediatric heart transplant recipients were included and underwent prospective monitoring of their immunosuppression and ethylene-diamine tetraacetic acid (EDTA) blood sampling for EBV load (copies/microg DNA) measurement using quantitative real-time polymerase chain reaction (PCR; TaqMan) during January 2001 to December 2006. RESULTS EBV load was measurable in 70% and was significantly increased (>2,000 copies/microg DNA) in 35% of the patients, with a median EBV load of 5,100 (range 0 to 50,665 copies/microg DNA). Increased EBV load was detected in patients receiving CsA-azathioprine or more than two doses of anti-thymocyte globulin (ATG) and in those <10 years of age, without any significant differences in CsA blood levels. Lowest or negative EBV load was measured in patients receiving CsA-mycophenolate mofetil (MMF) or CsA only. CsA blood levels were not predictable for increased EBV load or PTLD. Six patients developed a EBV-associated B-cell lymphoma (PTLD), among whom 4 (67%) were receiving CsA-azathioprine. CONCLUSIONS Frequent EBV load monitoring identifies patients at high risk for PTLD development. Azathioprine and ATG are major risk factors for increased EBV load and PTLD and patients may benefit from a change of immunosuppression in addition to pre-emptive anti-viral or anti-tumor strategies.

Abstract
Although most posttransplant lymphoproliferative disorders (PTLD) are related to Epstein-Barr virus (EBV) infection, approximately 20% lack detectable EBV (EBV-). It is uncertain whether the latter cases are truly distinct from EBV+ PTLD or possibly relate to another infectious agent. This study used gene expression profiling to further investigate the relationship between EBV+ and EBV- monomorphic B-cell PTLD, and to search for clues to their pathogenesis. Affymetrix HU133A GeneChips were used to compare 4 EBV+ and 4 EBV- cases of monomorphic B-cell PTLD. Hierarchical clustering successfully distinguished the EBV+ and EBV- groups. Relative to EBV- PTLD, 54 transcripts were over-expressed in EBV+ PTLD. The transcripts identified included IRF7 (a known regulator of EBV LMP1 expression), EBI2 (EBV-induced gene 2), and 3 that are interferon induced (MX1, IFITM1, and IFITM3). In addition, the EBV+ group contained 232 transcripts decreased relative to the EBV- group, including changes concordant with those previously reported after EBV infection of cultured B-cell lines. In summary, in a small group of monomorphic B-cell PTLD, EBV+ cases demonstrated a subset of gene expression changes associated with EBV infection of B cells. By contrast, EBV- PTLD lacked viral-associated changes suggesting that they are biologically distinct.

Abstract
Posttransplant lymphoproliferative disorder (PTLD) is a major complication of liver transplantation, but previous descriptions have been limited to case reports and small case series. We report a retrospective analysis of 17 consecutive cases of PTLD associated with liver transplantation. The median age at PTLD diagnosis was 47 years (range 19 - 63) with a median time of 25 months from liver transplantation to PTLD diagnosis (range 3 - 75). PTLD location was frequently extranodal (71%) and involved the transplanted liver (41%). PTLD histology consisted of nine (53%) monomorphic and eight (47%) polymorphic disease. EBV was present by in situ hybridization in 11 (79%) of 14 cases evaluated. Initial therapy included reduction in immunosuppression (RI) alone in 13 (76%) of 17 patients, resulting in 6 (46%) complete responses (CR) and 7 (54%) progressive disease (PD). Monoclonal CD20 antibody (rituximab) and CHOP chemotherapy were used as initial therapy or as second line after RI failure. Currently, five patients (29%) are alive in CR. Although detection and treatment of PTLD in liver transplant recipients remains problematic and upfront mortality is still high, long-term survival is possible. Further studies are necessary to better define treatment strategies.

Abstract
PTLD represent major post-transplant complications. The major etiologic factor is EBV. Association with cold agglutinin disease has not been described so far. We report a three-yr-old girl who developed oligoclonal EBV-negative plasmacytic hyperplasia as well as Coombs test-positive anemia one yr after multivisceral organ transplantation, performed after subtotal bowel resection for colointestinal aganglionosis and liver cirrhosis resulting from long-term parenteral nutrition. The patient was treated for plasmacytic hyperplasia with cyclophosphamide and prednisolone and achieved clinical remission. One yr later PTLD progressed possibly driven by EBV to DLBCL. The migration patterns of the amplified Ig heavy chain genes demonstrated a probable clonal relationship of the DLBCL to a clone almost present in the plasmacytic hyperplasia. This progression was accompanied by a rapid rise of cold agglutinin titers with symptoms of severe cold agglutinin disease, leading to right femoral and extern iliac vein thromboses requiring partial leg amputation. After four cycles of rituximab, cyclophosphamide, and prednisolone, the patient achieved complete PTLD remission and the cold agglutinins disappeared. Summarizing, PTLD may be accompanied by cold agglutinin disease, and both may be successfully treated by immuno-chemotherapy. The appearance of cold agglutinins in transplant patients may indicate PTLD development.

Abstract
Epstein–Barr virus (EBV) is a significant cause of morbidity and mortality in solid-organ transplant (SOT) recipients. The most serious complication of EBV infection in this population is post-transplant lymphoproliferative disorder (PTLD). EBV-viral load monitoring can be used to predict those SOT patients at high risk of PTLD, particularly those who are EBV seronegative prior to transplant. Surveillance EBV-load monitoring to inform pre-emptive reduction of immunosuppression has contributed to the decrease in the incidence of PTLD in SOT recipients. The use of the anti-CD20 antibody, rituximab, as a therapeutic agent is increasing, with anecdotal reports of positive outcomes. However, experience to date suggests that the use of this agent may not prevent recurrence of the tumor or improve cell-mediated immune responses to EBV. Future investigation of EBV-specific T-cell responses as an adjunct to monitoring, and the adoptive transfer of EBV-specific cytotoxic T lymphocytes appear likely in future attempts as a means to limit the consequences of EBV infection in the SOT population.

Abstract
Post-transplant lymphoproliferative disorder (PTLD) is a serious and still frequently observed complication of solid organ transplantation. Despite the recent introduction of anti B-cell monoclonal antibody therapy (rituximab) for treatment of PTLD, mortality rates remain high. Because PTLD often presents in a nonspecific way in clinically unsuspected patients, it is a major challenge to diagnose PTLD at an early stage. Epstein-Barr virus (EBV)-DNA load monitoring is a promising tool for the identification of patients at risk for PTLD development. However, there are some limitations of this method, and not all patients at risk for PTLD can be identified by EBV-DNA measurements alone. Therefore, it is of major importance to recognize early clinical signs and symptoms of PTLD. In this review, risk factors for PTLD development, disease presentation, and methods for early detection will be discussed. Special attention is given to allograft and digestive tract localization and the relation with time of onset of PTLD. The value and pitfalls of EBV-DNA load monitoring are discussed. In addition, because fluorodeoxyglucose (FDG)-positron emission tomography (PET) has shown to be a powerful tool for staging and response evaluation of malignant lymphoma, the role of FDG-PET for early diagnosis and staging of PTLD is addressed.
