Epstein-Barr virus (EBV) is a gamma herpesvirus associated with diseases ranging from asymptomatic viremia to post-transplant malignancies in kidney transplant recipients. EBV specifically is associated with post-transplantation lymphoproliferative disorder (PTLD), in kidney transplant recipients, with increased risk in EBV seronegative patients with EBV seropositive donors on intensified immunosuppression. The diagnosis of PTLD relies on clinical suspicion plus tissue biopsy with polymerase chain reaction (PCR) testing of blood currently used for risk determination in high-risk recipients...

Objective: To study the expression of membrane HLA-G (mHLA-G) and the receptor immunoglobulin-like transcript 2(ILT2) on lymphocyte and find their association with rejection and cytomegalovirus (CMV) infection after renal transplantation. Methods: A total of 88 cases of renal transplant recipients for the first time from February 2014 to February 2016 were studied in this work. Recipients can be divided into rejection group (n=12) and stable renal function group (n=41) according to whether rejection occurred...

BACKGROUND: New-onset diabetes after transplantation (NODAT) is a significant co-morbidity following kidney transplantation. Lower post-transplant serum magnesium levels have been found to be an independent risk factor for NODAT in adult kidney transplant recipients. METHODS: We undertook a retrospective analysis of risk factors for NODAT in pediatric renal transplant recipients at our institution with the aim of determining if hypomagnesemia confers a significant risk of developing NODAT in this patient population...

Cardiovascular disease is a major cause of morbidity, disability, and mortality in kidney transplant patients. Cumulative reports indicate that the excessive risk of cardiovascular events is not entirely explained by the increased prevalence of traditional cardiovascular risk factors. Atherosclerosis is a chronic inflammatory disease and it has been postulated that post-transplant immune disturbances may explain the gap between the predicted and observed risks of cardiovascular events. However, whereas concordant data suggest that innate immunity contributes to the posttransplant accelerated atherosclerosis, only few arguments plead for a role of adaptive immunity...

BACKGROUND & OBJECTIVES: Diarrhoea is the main clinical manifestation caused by intestinal parasitic infections in patients, with special reference to transplant recipients who require careful consideration to reduce morbidity and mortality. Further, molecular characterization of some important parasites is necessary to delineate the different modes of transmission to consider appropriate management strategies. We undertook this study to investigate the intestinal parasitic infections in transplant recipients with or without diarrhoea, and the genotypes of the isolated parasites were also determined...

Hemophagocytic lymphohistiocytosis (HLH) is an often fatal hyperinflammatory syndrome that may complicate malignancy, infection, rheumatic disease, or immunosuppression. HLH after kidney transplantation is most often triggered by infection, usually Herpes viruses such as cytomegalovirus and Epstein-Barr virus (EBV). It usually occurs early after transplantation. We present a case of HLH triggered by reactivation of EBV that pursued a rapidly fatal course within 6 days of receiving a deceased-donor kidney transplant...

BACKGROUND: The role of cytomegalovirus (CMV) in cancer development after transplantation remains uncertain. We aimed to determine the association between donor and recipient CMV serological status and the risk of cancer development after kidney transplantation. METHODS: Using data from the Australian and New Zealand Dialysis and Transplant (ANZDATA) Registry, we assessed the association between CMV donor/recipient (D/R) serological status and the risk of solid organ cancers in primary adult deceased-donor kidney transplant patients between 1990 and 2012...

RATIONALE: Resistant cytomegalovirus-mediated infections are increasing in solid organ recipient with few available alternative treatments. Brincidofovir is an oral broad-spectrum antiviral in development for prevention and treatment of viral infection, particularly cytomegalovirus. PATIENTS CONCERNS: Although brincidofovir is an analogue of cidofovir, previous studies reported no renal toxicity. DIAGNOSES: Here, we report 2 cases of severe tubular necrosis in solid organ recipients, 1 heart and 1 kidney transplant...

BACKGROUND: Solid organ transplantation (SOT) frequently is complicated by cytomegalovirus (CMV) infections. Cidofovir (CDV) is active against CMV, including many ganciclovir (GCV)-resistant mutants, but often is considered to be too nephrotoxic for use after organ transplantation. PATIENTS AND METHODS: Seven males and two females (median age 50.1 years), including two kidney/pancreas, four lung, one small bowel, and two hand recipients, received CDV for refractory CMV disease...

BACKGROUND: Infusion of recipient regulatory T cells (Treg) promotes durable mixed hematopoietic chimerism and allograft tolerance in mice receiving allogeneic BMT with minimal conditioning. We applied this strategy in a Cynomolgus macaque model. METHODS: CD4+CD25high Treg that were polyclonally expanded in culture were highly suppressive in vitro and maintained high expression of FoxP3. Eight monkeys underwent nonmyeloablative conditioning and MHC-mismatched BMT with or without Treg infusion...

BACKGROUND: Acute pancreatitis (AP) following KT is a rare and often fatal complication of the early post-transplant period. Common causative factors for AP are rare after KT; anti-rejection drugs as CyA, prednisone and MMF have been implicated, although evidence is not strong and we found no reports on possible causative role for mTOR inhibitors. CASE PRESENTATION: A 55-year-old Caucasian man with end-stage renal disease due to idiopathic membrano-prolipherative glomerulonephritis underwent single kidney transplantation (KT) from cadaveric donor...

INTRODUCTION: Tuberculosis (TB) is an important cause of morbidity and mortality in renal transplant recipients. Immunosuppressive drugs are one of the most important risk factor for post-transplant tuberculosis (PTTB). A paucity of data exists about the impact of the type of calcineurin inhibitor on PTTB. METHODS: In this retrospective study, all adult patients on calcineurin inhibitor-based immunosuppression were included. Patients receiving TB chemoprophylaxis were excluded...

BACKGROUND: The reasons for improved outcomes associated with preemptive kidney transplantation (PKT) are incompletely understood, and post-transplant complications have been scarcely investigated. METHODS: We evaluated the outcomes of PKT in both unmatched (n = 1060) and propensity score matched cohorts (n = 186) of adults who underwent living kidney transplant between 2000 and 2014. Outcomes were estimated glomerular filtration rate (eGFR), biopsy-proven rejection, cytomegalovirus (CMV) infection, post-transplant diabetes mellitus (PTDM), cardiovascular disease (CVD), graft failure (non-censored for death), and malignancy...

BACKGROUND: BK polyomavirus (BKV)-associated nephropathy is a threat to kidney allograft survival affecting up to 15% of renal transplant patients. Previous studies revealed that tubular epithelial cells (TEC) show a limited response towards BKV infection. Here we investigated the interplay between BKV and TEC in more detail. In particular, we questioned whether BKV suppresses and/or evades antiviral responses. METHODS: Human primary tubular epithelial cells (TEC) and peripheral blood mononuclear cells were infected with BKV Dunlop strain or other viruses...

BACKGROUND: Cytomegalovirus (CMV) has a role in chronic rejection and graft loss in kidney transplant (KTx) and lung transplant (LTx) recipients. In addition, donor CMV seropositivity is an independent risk factor for renal graft loss. The anti-CMV response might modulate this risk. Expression of programmed cell death 1 (PD-1), a receptor involved in viral-specific T-cell exhaustion, is influenced by a single nucleotide polymorphism called PD-1.3 (wild-type allele G, variant allele A)...

BACKGROUND: Gancyclovir-resistant (GanR) cytomegalovirus (CMV) remains an issue, especially in solid organ transplant (SOT) recipients. Some mutations in UL54 and UL97 confer this resistance. Long-lasting high-dose drug exposure, high viral load, together with lack of sufficient compliance with treatment may account for these mutations. The aim of this study was to detect UL97 and UL54 putative mutations conferring ganciclovir-resistance in renal organ transplant recipients with high CMV load...
