Post-transplant lymphoproliferative disorders (PTLD) are lymphomas that may arise in organ, bone marrow or stem cell transplant recipients who are taking immunosuppressive drugs to prevent rejection of the transplant. The likelihood of developing PTLD depends on the type of transplant. PTLD is a potentially severe complication of post-transplant treatment, with an uncertain prognosis. Lymphoproliferative disorders can also occur in people taking immunosuppressants for inflammatory bowel disease. This article will explore PTLD and discuss the experience of caring for patients who developed lymphoproliferative conditions and required emergency stoma formation...

Chronic active Epstein-Barr virus infection (CAEBV) is a prototype of EBV-associated T- and/or NK-cell (EBV+ T/NK-cell) lymphoproliferative disorders. Most subtypes of these are lethal. We established a unified treatment strategy composed of step 1 (immunochemotherapy: steroids, cyclosporine A, and etoposide), step 2 (multi-drug block chemotherapy), and step 3 (allogeneic hematopoietic stem cell transplantation; HSCT) for CAEBV and its related diseases. Allogeneic HSCT is the only cure for CAEBV with few exceptions...

Background: X-linked lymphoproliferative disease type 1 (XLP1) is a rare primary immune deficiency, which is caused by SH2D1A gene mutations. XLP1 is commonly associated with Epstein-Barr virus (EBV)-associated hemophagocytic lymphohistiocytosis, hypogammaglobulinemia, and/or lymphoma. The only curative treatment for XLP1 is allogeneic hematopoietic cell transplantation. However, published data detailing the clinical course of, and indications for, allogeneic hematopoietic cell transplantation in asymptomatic patients with XLP1 is lacking...

EBV-related PTLD developing after HSCT is a potentially life-threatening disease. HLH is uncommon after allogeneic HSCT. Data on outcome of patients with PTLD and concomitant HLH after allogeneic HSCT are limited. In this retrospective study, we collected demographic, clinical, laboratory, and outcome data for 408 patients who underwent allogeneic HSCT from 2006 to 2015. Graft source included CB (n = 135; 33.1%), PBSCs (n = 34; 8.3%), and BM (n = 239; 58.6%). Eight out of 408 patients (2%) developed EBV-PTLD with a median age at HSCT of 5...

There is an increased incidence of certain tumors and other neoplastic disease in organ allotransplant recipients receiving immunosuppressive therapy. Following clinical pig organ xenotransplantation, will there be a risk of the development of neoplasia in the pig graft or in other tissues transplanted with it, eg, lymph nodes? The incidence of neoplasia in young slaughterhouse pigs is very low (<0.005%), but in older pigs is largely unknown (as most pigs are killed within the first six months of life). However, lymphosarcoma, nephroblastoma, and melanoma have been reported in pigs...

In recent years, the cross talk between the liver and the immune system is being uncovered, in part by studying liver involvement in primary immune deficiencies (PID) and in part by investigating the alterations of the immune system following orthotic liver transplantation (OLT). Here we review some of the reciprocal interactions between the liver and the immune system. Patients with PID, particularly those involving inherited defects in T and B cells or innate immunity are prone to infections and inflammatory responses that often involve the liver...

The number of patients receiving hematopoietic stem cell transplantation (HSCT) is rapidly rising worldwide. Despite substantial improvements in peri-transplant care, pulmonary complications resulting in respiratory failure remain a major contributor to morbidity and mortality in the post-transplant period, and represent a major barrier to the overall success of HSCT. Infectious complications include pneumonia due to bacteria, viruses, and fungi, and most commonly occur during neutropenia in the early post-transplant period...

BACKGROUND: Multicentric Castleman disease (MCD) is an uncommon lymphoproliferative disease characterized by systemic inflammatory reactions associated with the dysregulated production of interleukin-6 (IL-6). In patients with MCD, renal involvement is uncommon, with only one report published regarding kidney transplantation (KTx) to treat end-stage renal disease (ESRD) secondary to MCD. Recent clinical observations have shown that IL-6 production is implicated in allograft rejection, while IL-6 receptor blockade (with tocilizumab [TCZ]) reduces alloantibody generation and thereby improves graft survival; however, the efficacy and safety of TCZ in MCD patients undergoing KTx is still unknown...

An ectopic pancreas, also known as pancreatic rest or heterotopic pancreas, consists of pancreatic tissue found in a location with no continuity with the anatomic pancreas. This lesion can occasionally cause gastrointestinal obstruction, ulceration or become inflamed and cause ectopic pancreatitis. We present the case of a 29-year-old immunocompromised female patient due to a previous kidney transplant. She presented with nausea and vague abdominal discomfort and was admitted for investigation and treatment of an acute kidney injury...

Post-transplantation lymphoproliferative disorder (PTLD) is a well-know complication after organ transplantation. We report a case of a patient who developed an extramedullary plasmacytoma-like PTLD around his transplanted kidney treated with standard multiple myeloma chemotherapy. Three years after benefiting of a deceased donor kidney transplant for an end stage kidney disease secondary to nephroangiosclerosis, our patient developed an extra-medullary plasmacytoma confined to the transplant compartment. The transplant function was unaltered, and due to the absence of reduction of the lesion after immunosuppression reduction, a chemotherapy by bortezomib-cyclophosphamide-dexamethasone (VCD) known to be efficient in multiple myeloma was initiated...

Background Epstein-Barr virus (EBV) DNA load monitoring in blood is essential for the diagnosis of EBV-associated diseases. However, the best-suited blood compartment for detection is still under discussion. The aim of this study was to evaluate the diagnostic value of EBV-DNA load in peripheral blood mononuclear cells (PBMC), plasma and whole blood (WB) samples. Methods A total of 156 patients, including 45 patients with infectious mononucleosis (IM), 57 patients with EBV-associated hemophagocytic lymphohistiocytosis (HLH) and 54 patients with post-transplant lymphoproliferative disorders (PTLD), were enrolled in this study...

Autologous T cells targeting Epstein-Barr virus (EBV) latent membrane proteins (LMPs) have shown safety and efficacy in the treatment of patients with type 2 latency EBV-associated lymphomas for whom standard therapies have failed, including high-dose chemotherapy followed by autologous stem-cell rescue. However, the safety and efficacy of allogeneic donor-derived LMP-specific T cells (LMP-Ts) have not been established for patients who have undergone allogeneic hematopoietic stem-cell transplantation (HSCT)...

OBJECTIVE: Paediatric solid organ transplantation is an increasingly successful treatment. Improved survival is paralleled by increased secondary complications of immunosuppression, including post-transplant lymphoproliferative disease (PTLD). PTLD frequently presents in Waldeyer's lymphatic ring. Adenotonsillar hypertrophy (ATH) is common in children, however in children after transplant, ATH may indicate PTLD. We review the literature on ATH and the role of adenotonsillectomy in children after transplantation...

Allogeneic hematopoietic stem cell transplantation is a curative option for patients with a variety of diseases. Transplantation from a related haploidentical donor is being increasingly utilized for patients who lack an available human leukocyte antigen matched related or unrelated donor. One of the strategies used for haploidentical transplants involves selective depletion of T cells expressing the αβ T cell receptor and CD19+ B cells prior to transplant. This allows for the removal of cells responsible for graft-versus-host disease and post-transplant lymphoproliferative disorder but maintains hematopoietic progenitor and stem cells for engraftment (CD34+ cells), as well as cells to elicit graft-versus-tumor effect and provide anti-infective activity (such as gamma-delta T cells and natural killer cells)...

Better prognostication of graft and patient outcomes among kidney transplant recipients with post-transplant lymphoproliferative disease (PTLD) in the rituximab era is needed to inform treatment decisions. Therefore, we sought to estimate the excess risks of death and graft loss in kidney transplant recipients with PTLD, and to determine risk factors for death. Using the ANZDATA registry, the risks of mortality and graft loss among recipients with and without PTLD were estimated using survival analysis. A group of 367 patients with PTLD (69% male, 85% white, mean age 43 years) were matched 1 to 4 to 1468 controls (69% male, 88% white, mean age 43 years), and followed for a mean of 16 years...

Data from World Health Organization estimates that the hepatitis C virus (HCV) prevalence is 3% and approximately 71 million persons are infected worldwide. HCV infection is particularly frequent among patients affected by renal diseases and among those in dialysis treatment. In addition to produce a higher rate of any cause of death, HCV in renal patients and in renal transplanted patients produce a deterioration of liver disease and is a recognized cause of transplant glomerulopathy, new onset diabetes mellitus and lymphoproliferative disorders...

Complications following lung transplantation may impede allograft function and threaten patient survival. The five main complications after lung transplantation are primary graft dysfunction, post-surgical complications, alloimmune responses, infections, and malignancy. Primary graft dysfunction, a transient ischemic/reperfusion injury, appears as a pulmonary edema in almost every patient during the first three days post-surgery. Post-surgical dysfunction could be depicted on computed tomography (CT), such as bronchial anastomosis dehiscence, bronchial stenosis and bronchomalacia, pulmonary artery stenosis, and size mismatch...

One hundred thirty-eight new Epstein-Barr virus (EBV) genome sequences have been determined. One hundred twenty-five of these and 116 from previous reports were combined to produce a multiple-sequence alignment of 241 EBV genomes, which we have used to analyze variation within the viral genome. The type 1/type 2 classification of EBV remains the major form of variation and is defined mostly by EBNA2 and EBNA3, but the type 2 single-nucleotide polymorphisms (SNPs) at the EBNA3 locus extend into the adjacent gp350 and gp42 genes, whose products mediate infection of B cells by EBV...
