Filter by:There has been no effective predicting tool to accurately predict BKV reactivation after kidney transplantation. The aim is to elucidate the use of flow cytometric analysis for both intracellular cytokines and surface activation markers for BKV-specific T cell response in kidney transplant recipients.
The investigators aim to investigate the association between renal volume measured through pre-donation CT auto-segmentation and postoperative renal function of both donors and recipients. After establishing the statistical significance of the association, the investigators intend to create and validate predictive models for renal function at surgery, 1 year, and 3 years postoperatively, incorporating various factors known to contribute to renal function deterioration.
Development of renal fibrosis is the irreversible culmination of various renal diseases and independently predicts adverse outcomes. Currently renal fibrosis can only be diagnosed by performing a renal biopsy. The procedure is invasive and is limited by sampling bias. In recent years there has been a significant development in magnetic resonance imaging (MRI) based techniques. MRI can provide highly detailed anatomical images. Other MRI measures allow quantitative measurements of perfusion, oxygenation, tissue stiffness and diffusion of water molecules within tissue. The combination of several MRI techniques sensitive to different biophysical tissue properties in a single scan session is referred to as multiparametric MRI (mpMRI). Emerging evidence suggests that mpMRI could represent a method for indirect characterization of renal microstructure and extent of fibrosis. So far, studies performed in living kidney donors and recipients have been mostly cross-sectional. For mpMRI to transition to the clinical setting there is a need for validation of MRI-based measures with currently used gold-standard methods for quantifying renal function and fibrosis. The aim of this prospective follow-up study in a cohort of living kidney donors, recipients and healthy controls is to investigate the utility of repeated mpMRI over a period of 2 years. MRI-based measures will be compared to current gold-standard methods for quantifying renal function and fibrosis. The investigators hypothesize that there will be significant correlations between MRI-based measures, renal function determined by precise measurement of glomerular filtration rate and extent of fibrosis determined by renal biopsy. MRI-based measures are expected to be predictive of renal function decline and development of renal fibrosis. This study could provide valuable data that will be helpful in moving the field of renal mpMRI forward, with the goal of providing a novel and non-invasive method for the diagnosis of renal pathology.
The goal of this observational study is to learn about the current status of illness perception and the distribution of coping styles in kidney transplant recipients. The main question clarifies the current status and experience of illness perception in post-transplant patients with different coping styles, and aims to provide a reference basis for intervention of illness perception in kidney transplant patients, with the aim of improving their current status of illness perception, optimizing their awareness of treatment management and self-care behaviors, and perfecting the modern medical service system. Participants will describe the main tasks participants will be asked to do.
The goal of this clinical trial is to evaluate cardiometabolic and inflammatory parameters in kidney transplant recipients after transitioning to a plant-based diet (PBD). The main aims of the study are as follows: - To test the feasibility of transiting renal allograft recipients who are > 3 months post-transplant to a PBD - To study the effect of a PBD on cardiometabolic parameters in kidney transplant recipients - To assess the effect of a PBD on peripheral blood Th17/Treg ratio and systemic inflammation in kidney transplant recipients Participants will be asked to: - Complete a 2-week investigator-designed PBD transition program - Follow a PBD for a minimum of 16 weeks - Consent for blood draws, urine samples, and fecal samples along with physical exams - Complete intermittent food frequency questionnaires and quality of life questionnaires - Periodically meet with investigators and other study participants Researchers will compare baseline measurements with future measurements for each participant.
Scoring systems that combine donor clinical and morphological parameters to predict outcome of kidney transplantation lack enough specificity to be generally accepted. Compare to classical histology, molecular assessment of renal tissue offers unbiased and technically robust approach. In this prospective 3-months' observational study procurement biopsies in 180 brain death donors will be performed. Using microarray which detect top differently regulated genes, conventional histology, urinary AKI biomarkers, renal function and clinical variables models predicting DGF and early graft scarring (IFTA, poor graft function) in recipients will be constructed. The associations of AKI in donors with distinct fibrosis atrophy and AKI molecular signals will be found. Molecular techniques and final models may help to improve the decision-making process for the acceptance of kidneys from marginal donors but more importantly, it may help clinicians to guide less toxic immunosuppression in identified problematic grafts.
In Poland, approximately 4.2 million people suffer from chronic kidney disease [1]. In December 2022, a total of 20,198 patients were dialyzed in the country, of which 96% by hemodialysis (HD) and 4% by peritoneal dialysis (DO). In 2022, kidney transplantation was performed in 2.6% of patients dialyzed using the HD method and in 15.4% of patients dialyzed using the DO method [2]. According to the data of the Organizational and Coordination Center for Transplantation "Poltransplant", in 2022 on the national waiting list 1,119 people were registered for kidney transplantation. The average age of those waiting was 49 years [3]. In Poland, according to data from 2022, the average waiting time for transplantation in the case of the first transplant from the moment of registration on the waiting list was 387 days, and 1,106 days from the start of dialysis. Data show that only 5.5% of patients undergoing renal replacement therapy are on the waiting list [3]. Therefore, a study was designed to examine the knowledge and attitudes towards kidney transplantation among dialysis patients. The study will include a representative group of dialysis patients from all voivodeships and aims to identify positive and negative aspects related to patients' attitudes towards kidney transplantation. The scientific value of the study is worth emphasizing, because so far in Poland no research has been conducted on the knowledge and attitudes towards kidney transplantation among dialysis patients in all voivodeships in the country. The study will identify the level of knowledge and attitudes of dialysis patients towards transplantation. The results of this study may contribute to the development and implementation of new educational and information programs that may increase the level of knowledge and influence attitudes towards transplantation, which may largely contribute to the increase in transplantation among people with chronic kidney disease.

Long-term allograft function in kidney transplant recipients (KTRs) remain suboptimal, and graft failure causes significant morbidity and mortality, with cardiovascular disease being the leading cause of death in KTRs and the most common cause of death with a functioning graft. Sodium-glucose cotransporter 2 (SGLT2) inhibitors safely lower cardiovascular and kidney disease risk in the non-transplant population, yet data in KTRs are lacking. This clinical trial seeks to establish the efficacy and safety of dapagliflozin, a SGLT2 inhibitor, for improving cardiovascular and kidney graft function in adult KTRs with type 2 diabetes and post-transplant diabetes, and to leverage innovate translational methods to define the underlying mechanisms of action.
