BACKGROUND: Kidney transplant (KT) recipients have a higher incidence of malignancy than the general population. Smooth muscle tumors (SMT), including leiomyosarcoma, are rare in kidney transplant recipients, and most cases are associated with Epstein-Barr virus (EBV) infection. CASE REPORT: A 57-year-old man received a deceased donor kidney transplant at the age of 53 years, with 5 human leukocyte antigen (HLA) mismatches. Before the transplantation, the patient was IgG positive for EBV viral capsid antigen (VCA), negative for IgM EBV VCA, and also negative for IgG EBV nuclear antigen (EBNA), suggesting a prior EBV infection...

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...

OIs present significant risks to patients following solid organ transplantation. The purpose of this study was to identify risk factors for the development of OIs after kidney transplantation in pediatric patients and to evaluate the impact of OIs on outcomes in this patient population. A single-center retrospective longitudinal cohort analysis including pediatric patients 21 yr of age or younger transplanted from July 1999 to June 2013 at an academic medical center was conducted. Patients were excluded if they received multi-organ transplant...

PTLD is a serious complication of both solid organ and BMT. This study assessed whether (18) F-FDG PET, when added to CT scan, had additional value in the initial evaluation of PTLD in pediatric patients and whether PET/CT at baseline can reliably guide biopsy. This retrospective study evaluated 34 consecutive pediatric patients (14 female), aged 3.5-17.0 yr (mean age: 9.9 yr, s.d.: 4.9 yr), who had undergone (18) F-FDG PET/CT from May 2007 to December 2014 at initial diagnosis of PTLD following heart (n = 13), lung (n = 8), kidney (n = 4), liver (n = 3), liver and bowel (n = 3), and bone marrow (n = 3) transplantation...

IMPORTANCE: Posttransplant lymphoproliferative disorder (PTLD) is an uncommon complication after solid organ transplants and hematopoietic stem cell transplants. Extranodal involvement in PTLD can involve several organ systems, including the central nervous system, bone marrow, lungs, gastrointestinal tract, and skin. Isolated involvement of the skin without systemic involvement in PTLD is rare. Primary cutaneous PTLD is generally categorized as either cutaneous T-cell lymphomas or cutaneous B-cell lymphomas, with variable Epstein-Barr virus (EBV) positivity...

West Nile virus (WNV) infection which is asymptomatic or mild in normal population, it may cause serious clinical conditions leading to death in eldery and immunosupressed patients. The virus is mainly transmitted by mosquito bites, however transfusion, transplantation, transplasental and nosocomial ways have also been reported to be responsible for viral transmission. It is known that WNV may cause life-threatining conditions such as central nervous system (CNS) infections especially in bone marrow and solid organ transplant recipients...

We report a rare case in which Epstein-Barr virus (EBV)-negative polymorphic B-cell post-transplant lymphoproliferative disorder (PTLD) and EBV-negative monomorphic T-cell PTLD [anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma (ALCL)] were observed simultaneously in the same cervical lymph node, 34 months after liver transplantation for hepatitis C liver cirrhosis. Although hepatitis C recurred after 2 months, he had no other complications until PTLD occurred 34 months post-transplantation...

Epstein-Barr virus (EBV) DNAemia in the first year posttransplantation has been studied extensively. There is a paucity of information on prevalence and sequelae of EBV infection in adult renal transplantation beyond the first year. This single-center study examines the relationship between EBV DNAemia and demographic, immunosuppressive, hematologic and infection-related parameters in 499 renal transplant recipients between 1 month and 33 years posttransplant. Participants were tested repeatedly for EBV DNAemia detection over 12 months and clinical progress followed for 3 years...

BACKGROUND: The early diagnosis of viral reactivation after kidney transplantation (KTX) is an unsolved problem. Survey of virus-specific T-cell responses may identify patients at risk for viral reactivation. We therefore quantified virus-specific CD8+ T-cells to evaluate their potential predictive value for viral reactivation and infection in KTX patients. METHODS: We quantified the virus-specific responses of CD8+ T-cells for CMV, EBV, HPV and HHV in 23 patients undergoing KTX for 6 mo after transplantation...

UNLABELLED: Primary central nervous system post-transplant lymphoproliferative disease (CNS PTLD) is a serious complication after solid organ transplantation that has not received much attention so far. However, it could become a more frequent problem with the introduction of new biological agents. METHODS: We identified five cases with CNS PTLD in our center who were transplanted between 1986 and 2007, three men and two women, with a mean age of 55.9 years (range 42-74)...

BACKGROUND: Epstein-Barr virus (EBV) plays a major role in the development of post-transplant lymphoproliferative disorder (PTLD), but there is an increasing awareness of EBV-negative PTLD. The clinical presentation of EBV-negative PTLD has not been as well characterised as EBV-positive cases. Further, there is limited knowledge on the clinical importance of diffuse large B-cell lymphoma (DLBCL) cell of origin subtype post-transplant. MATERIALS AND METHODS: We studied the role of EBV, hepatitis C (HCV) and DLBCL subtype in clinical presentation and survival in 135 post-transplant lymphomas diagnosed 1980-2006 in a population-based cohort of 10 010 Swedish solid organ transplant recipients...

Primary cutaneous posttransplant lymphoproliferative disorders (PTLD) are rare. This retrospective, multicenter study of 35 cases aimed to better describe this entity. Cases were (re)-classified according to the WHO-EORTC or the WHO 2008 classifications of lymphomas. Median interval between first transplantation and diagnosis was 85 months. Fifty-seven percent of patients had a kidney transplant. Twenty-four cases (68.6%) were classified as primary cutaneous T cell lymphoma (CTCL) and 11 (31.4%) as primary cutaneous B cell PTLD...

The development of new immunosuppressive drugs for kidney transplantation resulted both in better short-term outcomes and in decreased metabolic, cardiovascular, and nephrotoxicity risk. Belatacept belongs to a new class of immunosuppressive drugs that selectively inhibits T-cell activation by preventing CD28 activation and by binding its ligands B7-1 and B7-2. The result is an inactivation of costimulatory pathways. A comparative analysis of the BENEFIT and BENEFIT-EXT datasets showed belatacept regimens resulted in better cardiovascular and metabolic risk profiles than did cyclosporin A (CsA) regimens: belatacept likewise outperformed CsA in terms of lower blood pressure and serum lipids and less new onset diabetes after transplantation...

Full T-cell activation in alloimmunity requires the engagement of several costimulatory molecules. CTLA-4-Ig and its commercially available fusion proteins, belatacept and abatacept, are used to block CD80/86 and promote T-cell tolerance. Belatacept, a higher binding affinity molecule, is currently approved for clinical use in renal transplantation. The results of two Phase III clinical trials showed a similar patient/graft survival, with better renal function at a 3-year follow-up compared with conventional immunosuppression...

A 43-year-old female developed an Epstein-Barr virus (EBV)-positive post-transplant lymphoproliferative disorder (PTLD) in the central nervous system (CNS), 14 years after renal transplantation. One year prior to presentation, the patients' treatment regimen was altered from cyclosporine, azathioprine, and prednisone to mycophenolate mofetil and prednisone. Magnetic resonance imaging of the brain revealed lesions suspect for malignant lymphoma. The EBV real-time polymerase chain reaction (PCR) on peripheral blood was negative, but highly positive on cerebrospinal fluid...

Post-transplant lymphoproliferative disease (PTLD) is a well-known late complication of organ transplantation which incidence has increased after the introduction of more powerful immunosuppressive agents. A 58-year-old man performed ABO-incompatible living kidney transplantation in June, 2008. At 3 years and 9 months after the transplantation, the patient complained of general fatigue and dyspnea and was hospitalized with renal dysfunction. The clinical data in hospital showed acute rejection, but soluble IL-II exceeded 21700U/ml, and HE staining kidney graft showed a massive infiltration of atypical lymphocytes...

Solid-organ-transplant recipients are at high risk of developing cancer, including thoracic malignancies. Herein, we report on two cases of thymoma in solid-organ recipients. One case was a female kidney-transplant recipient who had a type B2, Masaoka stage IVA thymoma that was treated by extended surgical resection followed by postoperative radiation therapy. The second case was type A Masaoka II thymoma that occurred after a liver transplant. The role of EBV in the oncogenesis of thymoma is controversial...

A registry of posttransplant lymphoproliferative disorders (PTLD) was set up for the entire population of adult kidney transplant recipients in France. Cases of PTLD were prospectively enrolled between January 1, 1998, and December 31, 2007. Ten-year cumulative incidence was analyzed in patients transplanted after January 1, 1989. PTLD risk factors were analyzed in patients transplanted after January 1, 1998 by Cox analysis. Cumulative incidence was 1% after 5 years, 2.1% after 10 years. Multivariate analysis showed that PTLD was significantly associated with: older age of the recipient 47-60 years and >60 years (vs...
