Filter by:Medication non-adherence is a major problem in kidney transplant recipients; young people 12-24 years of age are at particularly high risk for non-adherence and graft failure compared to young children and adults. Given that poor medication contributes greatly to graft failure, clinically feasible and effective interventions are urgently needed to improve adherence, survival, and quality of life in this population. The broad aim of this prospective, 3-stage, sequential study is to improve medication adherence in adolescent kidney transplant recipients by: 1) adapting the successful Teen Adherence in Kidney transplant Effectiveness of Intervention Trial (TAKE-IT) intervention for use in 'real world' clinical care, 2) designing and testing a new portable electronic pillbox and companion tracking website interface, and 3) preliminary testing of the adapted intervention.
The purpose of this study is to increase awareness and knowledge regarding the risks and benefits of kidney transplantation and living donation amongst patients seeking kidney transplantation and their family and friends in Buffalo, New York.
This is a pilot study designed to investigate the alterations in the gut microbiome that occur during the course of kidney transplantation, liver transplantation, allogeneic hematopoietic stem cells and mesenchymal stem cells transplantation in association with the clinical outcomes.
Intra-patient variability (IPV) in tacrolimus is associated with premature graft loss. The rate of acute rejection episodes is higher in these patients, and acute rejection impacts negatively on graft survival. The prevalence of patients with high IPV is higher in African American patients (1-5). At the kidney transplant program of the University of Maryland, our investigators follow over 2.800 patients, with approximately 50% of the patients being of African American heritage, thus an ideal setting for the study.
Researchers are trying to determine if exercise will improve health and strength in kidney transplant patients.
This is an observational study in renal transplant recipients to evaluate the acceptability, feasibility, and clinical utility of TruGraf® testing in conjunction with standard clinical assessment. TruGraf is the first and only non-invasive test approved by Medicare to rule out silent rejection in stable kidney transplant recipients.
This is an observational study to evaluate TruGraf® testing in high immune risk kidney transplant recipients. TruGraf is the first and only non-invasive test approved by Medicare to rule out silent rejection in stable kidney transplant recipients.
The incidence of end stage renal disease (ESRD) is rapidly increasing, now affecting an estimated 7.4 million people worldwide. Numerous parameters such as demographic, clinical and functional factors drive the deterioration of the kidney, ultimately leading to ESRD. Although some ESRD prediction models have been derived in the past years, none of these models are dynamic: they do not integrate the repeated measurements recorded throughout individuals' follow-up. As highlighted in several studies, kidney function repeated measurements (i.e., trajectories) are highly associated with graft survival after kidney transplantation. The investigators made the hypothesis that these trajectories may bring relevant information in the context of graft survival risk prediction model. Hence, combining these trajectories with standard graft survival risk factors may enhance prediction performance. This could permit to derive a robust tool that could be updated over time by continuously capturing patient' personal evolution.

The gold standard for characterizing chronic kidney disease (CKD) is the glomerular filtration rate (GFR), which is commonly estimated in both native and transplanted kidneys for patient monitoring and therapeutic management and ultimately guides decision-making about whether a patient needs renal replacement therapy. In particular, the National Kidney Foundation has defined CKD stages according to estimated GFR (eGFR) values and in several studies, the eGFR slope or change has been found to be strongly associated with end stage renal disease (ESRD). However, little is known about the heterogeneity of eGFR evolution in time - i.e. eGFR trajectories - and the related progression to ESRD and death. To date, no studies have investigated eGFR trajectories in diversified cohorts and populations worldwide, although this approach could provide a better understanding of CKD evolution and hence improve risk stratification. In addition, determinants of eGFR trajectories remain poorly described. An unsupervised approach could allow examining eGFR trajectories over time and could lead to the identification of patient groups according to the probability of the progression of their kidney disease. Therefore, this study aims: 1. To identify the long-term eGFR trajectories after kidney transplantation using latent class mixed models; 2. To identify the clinical, immunological, histological and functional determinants of the eGFR trajectories using multinomial regressions; 3. To investigate the associations of the eGFR trajectories with the progression to ESRD and death. Based on the results, the investigators will provide an easily accessible tool to calculate personalized probabilities of belonging to eGFR trajectories after kidney transplantation, by using datasets from prospective cohorts and post hoc analysis of randomized control trial datasets.
