OBJECTIVES: How smoking history affects kidney allograft outcomes is unclear in the contemporary era of immunosuppression. Here, we examined a broad range of outcomes after kidney transplant, stratifying patients by smoking status documented at time of transplant, in a well-characterized clinical cohort. MATERIALS AND METHODS: This retrospective single-center analysis (2007-2015) included 744 kidney allograft recipients who had documentation of smoking exposure (median follow-up 1327 days posttransplant)...

The excess risk for cancer in kidney transplant recipients is substantial, but the allograft and patient survivals after cancer development are under-studied. This is a population-based cohort study of all primary live and deceased donor kidney transplant recipients in Australia and New Zealand between 1990-2012. The risks of overall graft loss and death with a functioning graft in kidney transplant recipients with and without incident cancer were determined using adjusted Cox regression analysis, with incident cancer considered as a time-varying covariate in the models...

HIV infection has been considered for a long time an absolute contraindication to transplantation. The introduction of highly active antiretroviral therapy has led to improved immunovirological control and increased survival in HIV-infected patients. Renal transplantation can now be performed if these patients are on stable highly active antiretroviral therapy and achieve undetectable viral load and a sufficient CD4 level, in the absence of untreatable infections and cancers. Highly active antiretroviral therapy and immunosuppressive medication should be maintained for life in these patients, raising the problem of multiple drugdrug interactions...

OBJECTIVES: To report the long-term survival of transplanted kidneys in patients with a continent urinary diversion. METHODS: Between January 1987 and July 2015, 16 patients with a median age of 37 years (range 21-63 years) underwent kidney transplantation on a continent urinary diversion. A total of 14 patients presented irreversible dysfunction of the lower urinary tract, and two patients had required radical cystectomy because of bladder cancer. All continent urinary diversions were carried out before the transplantation...

Kidney transplant recipients are at a high risk for developing malignancies with dermatologic cancers and lymphomas making up the bulk of these. Leukemia is rare in this cohort of patients. Kidney infiltration by leukemic cells is seen in about 34% of native kidneys based on autopsy studies. But leukemia infiltration of the kidney allograft has not been described much in the literature. Here we discuss the case of a 59-year-old kidney transplant recipient with acute myeloid leukemia (AML) who presented with acute kidney injury and his transplant kidney biopsy showed leukemic cell infiltration of the renal cortex...

The main aim of this study is to assess the safety and antitumor efficacy of a palladium(II) (Pd)-saccharinate complex with terpyridine. To characterize the Pd(II) complex in vitro, its cytotoxicity was evaluated using a water-soluble tetrazolium salt cell viability assay and the mechanism of cell death was assessed by DNA fragmentation/condensation and live cell imaging analyses. The antitumor efficacy and safety of the Pd(II) complex in-vivo were examined by analyzing reduction in tumor size, changes in body and organ weight, histopathological analysis of liver, kidney, and tumor sections, and biochemical analysis of serum in C57BL/6 mice...

BACKGROUND: Post-transplant malignancy (PTM) remains a concern among pediatric kidney transplant (PKT) recipients. STUDY DESIGN: Between 1963 and 2015, 884 pediatric (age 0 to 17 years old) patients received 1,055 PKTs at our institution. Cox proportional hazards models were constructed to identify risk factors for PTM after PKT with time-to-first-PTM as a primary outcome. Secondly, the hazard of death or graft loss was calculated in patients who developed PTM. RESULTS: Median patient survival was 33 years (interquartile range [IQR] 18...

Kidney transplant is the treatment of choice for end-stage chronic kidney disease. Kidneys generate 1,25-dihydroxyvitamin D (calcitriol) from 25-hydroxyvitamin D (calcidiol) for circulation in the blood to regulate calcium levels. Transplant patients with low calcidiol levels have an increased risk of metabolic and endocrine problems, cardiovascular disease, type 2 diabetes mellitus, poor graft survival, bone disorders, cancer, and mortality rate. The recommended calcidiol level after transplant is at least 30 ng/mL (75 nmol/L), which could require 1000-3000 IU/d vitamin D3 to achieve...

Allograft rejection constitutes a major complication of solid organ transplantation requiring prophylactic/therapeutic immunosuppression, which increases susceptibility of patients to infections and cancer. Beyond the pivotal role of alloantigen-specific T cells and antibodies in the pathogenesis of rejection, natural killer (NK) cells may display alloreactive potential in case of mismatch between recipient inhibitory killer-cell immunoglobulin-like receptors (KIRs) and graft HLA class I molecules. Several studies have addressed the impact of this variable in kidney transplant with conflicting conclusions; yet, increasing evidence supports that alloantibody-mediated NK cell activation via FcγRIIIA (CD16) contributes to rejection...

The native kidney is a reservoir for human immunodeficiency virus (HIV)-1 and a site of viral replication, similar to lymphoid tissue, gut-associated lymphoid tissue or semen. The ability of the virus to persist may result from either a true latency or sequestration in an anatomic site that is not effectively exposed to antiretroviral therapy. The presence of HIV in kidney epithelial cells will lead progressively to end-stage renal disease. For decades, HIV-infected patients were excluded from consideration for kidney transplantation...

It is unclear whether cancer-related epidemiology after kidney transplantation is translatable between countries. In this population-cohort study, we compared cancer incidence and all-cause mortality after extracting data for every kidney-alone transplant procedure performed in England and New York State (NYS) between 2003 and 2013. Data were analyzed for 18,493 and 11,602 adult recipients from England and NYS respectively, with median follow up 6.3 years and 5.5 years respectively (up to December 2014). English patients were more likely to have previous cancer at time of transplantation compared to NYS patients (5...

Malignancy is a leading cause of morbidity and mortality in organ transplant recipients who receive immunosuppression. Cancers associated with viruses such as nonmelanotic skin cancer and Kaposi sarcoma occur in allograft recipients at rates that far exceed that in the general population. The increased risk and tumor type may depend not only on degree of immune system modulation but also on the type of organ transplanted. In kidney transplant recipients, the risk of cancers such as prostate and breast does not seem to be increased...

The incidence of malignancy is greater in kidney transplant recipients compared to the general population, though the higher risk is not equally distributed to all types of cancers. In face of the increased longevity of renal transplant recipients, certain cancers, such as acute leukemias, are becoming more prevalent. Acute myeloid leukemia (AML) typically presents with cytopenias and infections, both common findings after kidney transplantation. Therefore, the diagnosis of AML may be initially overlooked in these patients...

BACKGROUND: Spindle cell lipoma is an uncommon variant of lipoma and usually occurs as a solitary, subcutaneous, and well circumscribed lesion in the posterior neck, shoulders, and back of older men. Primary renal lipomas are rarely reported. Spindle cell lipoma in the kidney has not been previously described in the literature. CASE REPORT: A 60-year-old Chinese man suffered graft failure 10 years after living related donor kidney transplantation. During cancer surveillance, he was found to have a mass in the renal allograft, which increased in size and was suspicious for renal cell carcinoma on computerized tomographic scan...

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...

Cancer immunotherapy, especially the use of checkpoint inhibitors, is expanding and can be efficacious in organ transplant recipients with malignant neoplasia. In this review, we summarize clinical findings and evolution of several patients treated with CTL4-4 or PD-1 inhibitors reported in the literature. The CTL-4 inhibitor ipilimumab has been safely used in several liver and kidney allograft recipients. PD1-inhibitors look promising for tumor shrinking, but acute rejection is the rule, so they should be avoided in recipients of life-saving organs...

Anti-tumor necrosis factor-α (TNFα) therapy has improved the prognosis of many chronic inflammatory diseases. It appears to be well-tolerated by liver-transplant patients. However, their use and their safety in kidney-transplant patients have yet to be determined.In this retrospective study, we identified 16 adult kidney-transplant patients aged 46.5 years (34-51.8) who received anti-TNFα therapy from 7 kidney transplantation centers. The indications for this treatment included: chronic inflammatory bowel disease (n = 8), inflammatory arthritis (n = 5), AA amyloidosis (n = 1), psoriasis (n = 1), and microscopic polyangiitis (n = 1)...

Galectins are evolutionary conserved β-galactoside binding proteins with a carbohydrate-recognition domain (CRD) of approximately 130 amino acids. In mammals, 15 members of the galectin family have been identified and classified into three subtypes according to CRD organization: prototype, tandem repeat-type and chimera-type galectins. Galectin-3 (gal-3) is the only chimera type galectin in vertebrates containing one CRD linked to an unusual long N-terminal domain which displays non-lectin dependent activities...
