We present two cases of transmission of a pancreatic adenocarcinoma from a single donor to two kidney transplant recipients. Autopsy of the donor revealed a pancreatic adenocarcinoma that had already spread locally to the regional lymph nodes and had not been detected at the time of organ procurement. Both recipients were carefully monitored, as neither consented to graft nephrectomy.

The aim of this study was to evaluate the safety and efficacy of autologous MSCs in combination with standard therapy in KTRs with biopsy-proven chronic active antibody-mediated rejection (AMR). Patients with biopsy-proven chronic active AMR received treatment with autologous bone marrow-derived MSCs (3 × 10 cells/kg iv) after completion of standard therapy and were followed for up to 12 months.

Citrate has become the standard anticoagulant in acute renal replacement therapy and is widely used in various intermittent hemodialysis modalities, especially for patients with contraindications for heparin. With the increased adoption of medium cut-off membranes, experience with regional citrate anticoagulation is needed.

Due to the shortage of deceased and genetically- or emotionally-related living donors, living unrelated paid donor (LURpD) kidney transplantation has been considered; however, this practice may result in medical, ethical and social dilemmas, induce organ trading (commodification), and even criminal activities. Commodification also risks undermining public trust in the transplant system and impeding the development of proper altruistic or deceased donor programs by ignoring altruism, volunteerism, and dignity. However, despite many objections by authoritative organizations, black market practices are involved in up to 10% of all transplants worldwide.

Considering scarcity of publications on previous disasters, we reviewed transplantation practice during the recent COVID-19 pandemic, and dwelled upon this experience for guiding transplantation strategies in the future pandemic and non-pandemic catastrophes. We strongly suggest continuing transplantation programs during mass disasters, if medical and logistic operational circumstances are appropriate.

Here we investigated whether spot urine protein excretion in the first year following transplantation associates with allograft rejection phenotype at 1-year surveillance biopsies and occurrence of donor-specific antibodies (DSA). This prospective, observational national-cohort study included 139 non-sensitized patients who received a deceased donor kidney transplant between December 2014 and 2018.

Patients And Methods: We retrospectively analysed the AVF outcome and complications in all adult kidney allograft recipients transplanted between January 1st, 2000 and December 31, 2015 with a functional AVF at the time of transplantation. Follow-up was until December 31, 2019.
Background: We investigated 10-year trends in deceased donor kidney quality expressed as the kidney donor risk index (KDRI) and subsequent effects on survival outcomes in a European transplant population.
Methods: Time trends in the crude and standardized KDRI between 2005 and 2015 by recipient age, sex, diabetic status and country were examined in 24 177 adult kidney transplant recipients in seven European countries. We determined 5-year patient and graft survival probabilities and the risk of death and graft loss by transplant cohort (Cohort 1: 2005-06, Cohort 2: 2007-08, Cohort 3: 2009-10) and KDRI quintile.
More than 40-year hemodialysis survivors are living evidence of the achievements of hemodialysis therapy. We present the case reports of three patients treated by chronic hemodialysis for 47 (Patient 1), 43 (Patient 2), and 42 years (Patient 3) from a single center. These patients possess characteristics that were already shown to be associated with improved long-term survival: initiation of hemodialysis at a young age, absence of diabetes, and a relatively low and stable body weight with good nutritional status.

This study aimed to determine the effects of guided functional training added to the intradialytic cycling on dialysis adequacy and biochemical parameters in hemodialysis patients.
View Article and Find Full Text PDFThe purpose of this study was to define if Outcomes Expectations for Exercise (OEE) and Decisional Balance (DB) scales predict adherence to guided exercise programs and associate with the improvement in physical performance in the dialysis population.

This is the first randomised controlled trial on the effects and sustainability of functional training and counselling in addition to intradialytic cycling. Patients were randomly assigned to a kinesiologist-guided functional training in addition to intradialytic cycling (n = 20, experimental group) or intradialytic cycling only (n = 20, control group) over 16 weeks.

In this single-center, placebo-controlled, double-blind trial we studied whether vitamin D receptor activator paricalcitol might reduce proteinuria. Patients with urinary protein-to-creatinine ratio (UPCR) ≥20 mg/mmol despite optimization of the renin angiotensin aldosterone system (RAAS) blockade were randomly assigned to receive 24 weeks' treatment with 2 μg/day paricalcitol or placebo.

Methods: 140 PE treatments were performed using either 4% or 15% citrate at a comparable dose. Paired samples of postfilter blood and filtered plasma were taken for iCa measurements with a point-of-care analyzer.
Aims: Paricalcitol, a selective vitamin D activator, decreases proteinuria and may reduce graft failure risk in kidney transplant recipients. In this study, we evaluated the effect of paricalcitol on renin-angiotensin system (RAS) activity as well as interleukin (IL)-6 and transforming growth factor (TGF)-β plasma concentrations as biomarkers of inflammation and fibrosis.
Methods: This placebo-controlled, double-blind trial enrolled a national cohort of kidney transplant recipients with urinary protein-to-creatinine ratio (UPCR) ≥ 20 mg/mmol despite optimization of the RAS blockade.
Background: Tacrolimus has a narrow therapeutic drug window but high inter- and intrapatient variability. Our aim is to construct a model able to predict optimal maintenance tacrolimus predose concentration (C) in kidney transplant patients. Here we present our study design and genotype and variant allele frequencies for the selected single nucleotide polymorphisms of genes involved in tacrolimus metabolism in our national cohort of kidney transplant recipients.

We hypothesized that an increase in estimated protein excretion rate (ePER) from spot urine samples is associated with graft rejection and predicts rejection phenotype.
Methods: 151 patients who had undergone first-indication kidney biopsy due to graft dysfunction beyond 3 months after transplant were identified from a national cohort of 616 transplant recipients between 2000 and 2012 (25%).

Background: Periodontal diseases have systemic inflammatory effects and have been adversely associated with cardiovascular diseases, which are also the most frequent cause of death in the end-stage renal disease. The aim of this cross-sectional study was to investigate the oral health and serum biomarkers among the hemodialysis (HD) patients in Slovenia.
Material And Methods: 111 HD patients were periodontally examined and their sera were assayed for C reactive protein (CRP), cardiac troponin T (TnT), nitrite/nitrate (NOx) and antibody levels to A.
Background: Regional citrate anticoagulation (RCA) during hemodialysis interferes with calcium homeostasis. Optimal ionized calcium (iCa) target range during RCA and consequent calcium balance are unknown.
Methods: In a randomized controlled trial (ACTRN12613001029785) 30 chronic hemodialysis patients were assigned to normal (1.
Purpose: Although a population's senescence rate is classically measured as the increase in mortality rate with age on a logarithmic scale, it may be more accurately measured as the increase on a linear scale. Patients on dialysis, who suffer from accelerated senescence, exhibit a smaller increase in their mortality rate on a logarithmic scale, but a larger increase on a linear scale than patients with a functioning kidney transplant. However, this comparison may be biased by population heterogeneity.
