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: New-onset diabetes mellitus after transplantation (NODAT) is a well-known complication of transplantation. OBJECTIVE: To determine the correlation between CMV infection and NODAT. METHODS: Retrospectively, we detected CMV replication (PCR) in every month after renal transplantation in the first 12 months of the procedure in a homogenous group of patients from the immunosuppression point of view. RESULTS: In 167 patients (64 with NODAT and 103 in the control group), the average amount of CMV viremia was not significantly different between the NODAT and the control group (p=0...

BACKGROUND: Cytomegalovirus seropositivity is an independent risk factor for atherosclerosis in patients with ESRD. Donor CMV seropositivity is associated with higher graft loss. Dendritic cells, macrophages and Th17 lymphocytes are defined as producers of IL-23. IL-23 is thought to be involved in the promotion of Th17 cell polarization. Latent CMV-induced Th17 might be involved in the pathogenesis of CMV infection in patients with ESRD. We aimed to evaluate associations of Th17-dependent cytokines with ESRD, CMV status and post-transplant outcome in kidney transplantation...

The mortality in Strongyloides hyperinfection syndrome (SHS) is alarmingly high. This is particularly common in bone marrow, renal, and other solid organ transplant (SOT) patients, where figures may reach up to 50-85%. Immunosuppressives, principally corticosteroids, are the primary triggering factor. In general, the clinical features of Strongyloides stercoralis hyperinfection are nonspecific; therefore, a high index of suspicion is required for early diagnosis and starting appropriate therapy. Although recurrent Gram-negative sepsis and meningitis have been previously reported, the combination of both cytomegalovirus (CMV) and strongyloidiasis had rarely been associated...

BACKGROUND: The cytomegalovirus (CMV) donor-positive/recipient-positive (D+/R+) population is the largest proportion of renal transplant recipients (RTR). Guidelines for prevention of CMV in the intermediate-risk D+/R+ population include prophylaxis with valganciclovir (VGCV) 900 mg/day for 3 months. This study is the first head-to-head analysis comparing the efficacy and safety CMV prophylaxis of VGCV 450 vs. 900 mg/day for 3-months in D+/R+ RTR. METHODS: A multicenter, retrospective analysis evaluated 478 adult RTR between 01/2008 and 10/2011...

Whilst it is established that CMV disease affects NK-cell profiles, the functional consequences of asymptomatic CMV replication are unclear. Here we characterise NK cells in clinically stable renal transplant recipients (RTRs; n = 48) >2 years after transplantation. RTRs and age-matched controls (n = 32) were stratified by their CMV serostatus and the presence of measurable CMV DNA. CMV antibody or CMV DNA influenced expression of NKG2C, LIR-1, NKp30, NKp46 and FcRγ, a signalling adaptor molecule, on CD56(dim) NK cells...

The first kidney transplantation was performed in 1951 and ever since then living donor transplantation became a more and more important solution for patients with end-stage renal disease (ESRD). Renal transplantation is a life-saving procedure. Morbidity and mortality on waiting-lists are strongly correlated with the time of dialysis and end-stage renal disease is one of the most important causes of death; this is the reason why transplantation has to be performed as soon as possible in order to reduce the time of dialysis...

Observation that 1,25-Dihydroxyvitamin-D3 has an immunomodulatory effect on innate and adaptive immunity raises the possible effect on clinical graft outcome. Aim of this study was to evaluate the correlation of biopsy-proven acute rejection, CMV infection, BKV infection, with 1,25-Dihydroxyvitamin-D3 deficiency and the benefit of calcitriol supplementation before and during the transplantation. Risk factors and kidney graft function were also evaluated. All RTRs received induction therapy with basiliximab, cyclosporine, mycophenolic acid, and steroids...

Cytomegalovirus (CMV) infection in patients with liver transplantation (LT) remains a highly prevalent complication with a significant increase in morbidity and mortality. However, CMV-associated meningoencephalitis is rarely diagnosed, and treatment is very difficult. The aim of the present report is to review the experience of successful treatment with combined ganciclovir and foscarnet of CMV-associated meningoencephalitis refractory to ganciclovir alone in a hemodialysis (HD) patient after LT. A 54-year-old woman with end-stage renal disease on HD developed a seizure with loss of consciousness...

BACKGROUND: Granulocyte and monocyte adsorptive apheresis (GMAA) is widely used as a treatment for active ulcerative colitis (UC) in Japan. Much attention has been paid to the possibility of GMAA for the treatment and control of cytomegalovirus (CMV) reactivation in patients with refractory UC and concomitant CMV infection. In this study, the effects of the combination of GMAA and antiviral therapy were examined in renal transplant recipients with concomitant CMV infection. METHODS: Combination therapy of GMAA and antiviral drugs was performed 9 times in 7 renal transplant recipients with concomitant CMV infection...

Mizoribine (MZR) is an immunosuppressive agent that exhibits a less potent immunosuppressive effect at doses up to 3 mg/kg/d. We investigated whether high-dose MZR is effective and safe for renal transplant patients in conjunction with cyclosporine (CsA), basiliximab, and corticosteroids. Ninety Japanese renal transplant patients were administered MZR (6 mg/kg/d), CsA (7 mg/kg/d), prednisolone (maintenance dose, 10 mg/d), and basiliximab (20 mg/body). They were compared with a control group of 81 renal transplant patients who received mycophenolate mofetil (MMF; 1500 mg/d), CsA, prednisolone, and basiliximab...

In spite of the improvements in the clinical management of solid organ transplant (SOT) recipients provided by immunosuppresion and universal prophylaxis, human cytomegalovirus (CMV) infections continue to be one of the most leading causes of morbidity and mortality. Cell-mediated immunity specific to CMV (CMV-CMI) plays an important role in the control of CMV replication. Therefore, monitoring of CMV-specific T-cell response can be used to predict individuals at increased risk of CMV disease. The aim of this study was to investigate the levels of CMV-specific interferon (IFN)-γ producing CD4(+) and CD8(+) T cells in kidney transplant recipients before and after the transplantation, by cytokine flow cytometry...

Sequencing of Cytomegalovirus (CMV) genes to investigate antiviral resistance is a growing area of interest as treatment for CMV infection becomes more widely available and used. Using conventional sequencing methods, we identified a deletion in UL54 gene, del524, which conferred resistance to ganciclovir in a renal transplant recipient, in the absence of a co-existing resistance-conferring mutation in UL97 gene. This case report reinforces that both UL97 and UL54 genes should be sequenced when exploring CMV antiviral resistance as mutations have been identified in both genes independently of each other...

BACKGROUND: In renal transplant patients, pneumonitis may be caused by cytomegalovirus (CMV pneumonitis). This condition is usually accompanied by CMV viremia. However, CMV may also reactivate locally in the lungs of renal transplant patients with pneumonitis due to other pathogens. The impact of local CMV replication/reactivation in the lungs is unknown. MATERIAL AND METHODS: All renal transplant patients at the Duesseldorf transplant center in the time from 01/2004 to 1/2008 were analyzed concerning pulmonary CMV replication in the setting of pneumonitis...
