Potential Biomarkers of the Severity of Endothelial Damage in End-stage Chronic Kidney Failure
End-stage Chronic Kidney FailureThe principal objective of this study is to qualify markers of oxidative stress in inflammatory cells (monocytes) in patients with stage 3 kidney failure (diabetic or not), and patients with end-stage kidney failure (diabetic or not), who require dialysis. The evaluation of these markers will be done by the activation and localization of proteins implicated in vascular tone and oxidative stress in monocytes, correlated with the distribution of cholesterol sphingomyelin within planar rafts and caveolae. The aim is to describe their evolution under treatment, which could lead to interventional studies.

Comparison of a TauroLock™ Based Regimen to 4% Citrate as Lock Solution in Tunneled Haemodialysis...
Catheter InfectionsEnd-stage Renal DiseaseCatheter infections and dysfunctions are a major cause of morbidity and mortality in haemodialysis patients. According to the US Renal Data System, infection is the second leading cause of death in dialysis patients and the leading cause of catheter removal and morbidity in patients with end-stage renal disease. There is evidence that catheter lock solutions containing taurolidine reduce the risk of catheter related infections and improve catheter patency. Lock solutions have a local, but no systemic effect. In this study a taurolidine based lock regimen (TauroLock™-Hep500, Tauropharm, Waldbüttelbrunn, Germany, 2x/week and TauroLock™-U25.000, Tauropharm, Waldbüttelbrunn, Germany, 1x/ week) will be compared to 4% citrate (CitraFlow™ 4%, MedXL, Montreal, Canada, 3x/week) as standard lock solution. The objective of this study is to evaluate if a TauroLock™ based regimen to lock tunneled haemodialysis catheters has reducing effects on catheter related blood stream infections and catheter dysfunctions.
Exercise in Peritoneal Dialysis Patients (PDEX)
Peritoneal DialysisKidney Failure1 morePatients with end-stage kidney disease (ESKD) receiving peritoneal dialysis (PD) are physically inactive, resulting in poor physical function and reduced quality of life. The aim of this pilot trial was to test the study feasibility of a combined resistance and cardiovascular exercise program (recruitment and retention rates) and report adherence and adverse events. The intervention (I) group received monthly exercise physiologist consultations, exercise prescription (resistance and aerobic exercise program using exercise bands) and weekly phone calls over 12 weeks. Control (C) group received normal care. Feasibility outcomes were exercise adherence rates and adverse events. Secondary measures included physical function measures and patient-reported outcome measures (PROMs)

High-Intensity Interval Training and Regulatory T Cells
End Stage Renal DiseaseRegulatory T cells (Tregs) are a small population of T cells compromising of 1% to 5% of the total T cells in the body but they are playing a fundamental role in the maintenance of the immune homeostasis. These cells modulate the immune system by suppressing the effector activity and thus preventing autoimmune diseases and chronic inflammatory processes. Treg cell numbers have shown to increase with physical activity, and this increment has been directly correlated with exercise intensity. These results suggest that the increased Treg frequency may contribute to the beneficial effects of exercise on disorders associated with autoimmune disease or chronic low-grade inflammation such as atherosclerosis, diabetes mellitus, chronic kidney disease or cancer. The overall purpose of this study is to determine the influence High-intensity interval training (HIIT) on the frequency and quality of peripheral Treg cells.
Evaluation of Anti-rejection Drug, Tacrolimus, in African-Americans With Kidney Transplant
Kidney DiseaseEnd-Stage2 moreIn spite of conventional immunosuppression with lymphocyte-depleting induction followed by tacrolimus- and mycophenolate-based regimens, African American (AA) renal transplant recipients experience higher rates of acute rejection (AR), donor specific antibodies (DSA), and graft failure. Envarsus Extended-Release (XR)® (ENV) is a novel extended-release formulation of tacrolimus with a favorable pharmacokinetic profile, even in the setting of CYP3A5*1 allele (rapid metabolizers). The investigator will evaluate the safety and efficacy of early dose escalation with ENV in AA recipients. The study hypothesis is that higher tacrolimus target concentrations may be achieved without typical dose-limiting toxicities, and this may ultimately result in lower incidence of early AR, DSA, and graft loss.

Surrogate Markers for Sudden Cardiac Death in Patients With Diabetes Mellitus and End Stage Renal...
Diabetes Mellitus Type 2End Stage Renal DiseaseAim: Patients with type 2 diabetes mellitus (T2DM) and hemodialysis due to diabetic nephropathy exhibit a high risk for sudden cardiac death (SCD). Preliminary data suggest that beta-blocker treatment may reduce arrhythmias and mortality in this high-risk population. However, no results from large-scale clinical outcome trials with beta-blockers exist in this patient group and a broad, scientifically unapproved use of beta-blocker treatment may not be justified due to potential harmful side-effects such as AV-block or hypotension. In addition, we are lacking identified ECG surrogate parameters for SCD in this high-risk population and on the occurrence of arrhythmias in temporary relationship to hemodialysis sessions. Therefore, the present study will identify surrogate parameters of SCD in hemodialysis patients with T2DM and in an interventional trial investigate the suppressive effect of beta-blockers on these identified ECG markers.
