Increasing Live Donor Kidney Transplantation Through Video-based Education and Mobile Communication

The study is a- 2-arm randomized controlled trial among patients presenting for kidney transplant evaluation at a single transplant center to compare the effects of a patient-based self-learning and outreach intervention about living-donor kidney transplantation (KidneyTIME) versus usual care for living-donor kidney transplant knowledge, concerns, readiness, access behaviors, and living-donor inquiries over 12 months follow-up. Following consent and baseline assessment, participants were randomized, stratified by self-reported race, with equal allocation to 2 treatment arms: the KidneyTIME intervention and usual care.

Post-market Surveillance Study of the BD® WavelinQ™ EndoAVF System

A prospective, single-arm, multi-center post-market surveillance study of the BD® WavelinQ™ EndoAVF System for the Creation of Arteriovenous (AV) Fistula in Patients Requiring Dialysis.

Evaluation of the Radial Artery Deviation And Reimplantation Technique for Primary Hemodialysis Access Creation

The Radial Artery Deviation And Reimplantation (RADAR) technique is a new approach for the construction of hemodialysis arteriovenous fistula. In this technique, the radial artery pedicle is deviated towards the minimally dissected cephalic vein at the wrist. The aim of this study is to compare the safety and efficacy of this technique with the traditional end-cephalic to side-radial arteriovenous fistula, currently used as a first line vascular access in hemodialysis patients. The hypothesis is that the minimal dissection concept used in the RADAR inhibits venous juxta-anastomotic neointimal hyperplasia and stenosis, and lead to higher rates of maturation and patency.

Xeltis Hemodialysis Access Graft: aXess Pivotal Study

A prospective, single arm, non-randomized pivotal study to evaluate the safety and performance of the Xeltis hemodialysis access graft in subjects older than 18 years with end-stage renal disease, who plan to undergo hemodialysis for at least the first 6 months after study access creation.

The Role of Toll-like Receptor-4 in Periodontitis Patients With End-stage Renal Disease in a Sample of Egyptian Population

Chronic kidney disease (CKD) is a significant public health issue in Egypt, leading to end-stage renal disease (ESRD). ESRD patients often suffer from oral abnormalities due to the disease and medications. Periodontitis is linked to systemic diseases, including renal disease, with inflammation playing a key role. TLR4 genetic variations may influence susceptibility to CKD and periodontitis. This study investigates the association between TLR4 \[Gly/Thr (rs2149356)\] polymorphism and chronic periodontal disease in ESRD patients in Egypt.

Study the Effect of Niacin on Lipoprotein (a) Concentration and Hyperphosphatemia in Hemodialysis Patients

The goal of this clinical trial is to learn if Niacin has an effect on lipoprotein (a) concentration and hyperphosphatemia, which represent strong risk factors for cardiovascular diseases, in End-stage renal disease (ESRD) patients undergoing hemodialysis. It will also learn about the safety of Niacin. The main questions it aims to answer are: * Does Niacin lower lipoprotein (a) concentration? * Does Niacin treat hyperphosphatemia in End-stage renal disease (ESRD) patients undergoing hemodialysis? Researchers will compare Niacin to a control group (taking no drug) to see if drug Niacin works to treat hyperphosphatemia and lower lipoprotein (a) concentration. Participants will: * Take drug Niacin or no drug every day for 3 months * Visit the clinic once every 2 weeks for checkups and tests All Patients will be subjected to the following: 1. Informed consent. 2. Demographics and history taking: Using Patient Data sheet. 3. Laboratory evaluation including: Kidney function tests: blood urea,serum creatinine, albumin ,uric acid. Complete blood count (CBC). Lipid profile:Lipoprotein (a),total cholesterol,triglyceride,high density lipoprotein (HDL), low density lipoprotein (LDL). Phosphorous, calcium, sodium, parathyroid hormone (PTH), alkaline phosphatase (ALP). C-reactive protein (CRP).

Goals of Care Conversations Study

The long term goal is to improve quality of care in Veterans with serious illnesses by aligning medical care with Veterans' goals and values. The objective of this study is to use a sequentially randomized trial to determine what implementation strategies are effective to increase early, outpatient goals of care conversations. The study will use interviews with and surveys of medical providers, patients, and caregivers, along with medical record data. This work is significant because it tests ways Veterans can express their goals and preferences for life sustaining treatments and have them honored.

Changes in Renal Perfusion During Hemodialysis in Patients with End-stage Renal Disease

Residual renal function (RRF) characteristically declines after patients with end-stage renal disease (ESRD) initiate dialysis. Although RRF preservation correlates with improved patient\'s quality of life and survival prospects, poor understanding of the pathophysiology underlying RRF decline limits protection strategies.

Evaluation of the Level of Expression of CD45RC on T Lymphocytes as a Predictive Biomarker of Acute Rejection After Renal Transplantation

Chronic renal failure is a major public health problem in industrialized countries, due to its frequency - about 3 million patients in France - and its socio-economic impact. At the end stage of renal failure, renal transplantation is the best treatment, allowing an improvement in patient survival compared to treatment by extra-renal purification. Despite improved immunosuppressive strategies, allograft rejection is common in transplantation - between 15% and 25% in the first year - and is associated with lower renal graft survival. Different risk factors for rejection have been well identified, such as the young age of the recipient or a high number of human leukocyte antigen (HLA) incompatibilities between the donor and the recipient. However, these risk factors do not accurately identify the risk of acute rejection in order to optimize and individualize immunosuppressive strategies. Also, the search for biomarkers to predict allograft tolerance prior to transplant is a major goal in renal transplantation. The onset of acute rejection is caused by the ability of the recipient's T cells to recognize alloantigens. The CD45 molecule is a highly expressed tyrosine phosphatase on the surface of the lymphocytes that plays an important role in the activation of the T cell. Investigators showed that the level of expression of CD45RC on T lymphocytes was associated with the risk of acute rejection. Thus, from a retrospective cohort of 89 renal transplant patients followed, recipients with a high percentage of circulating CD8 lymphocytes expressing high CD45RC (CD45RChigh) before transplant had a 5 to 8-fold higher risk of developing acute rejection of allograft during follow-up (11-year average follow-up) compared to recipients with a low percentage of CD8+CD45RChigh. The purpose of this study is to confirm the first retrospective results on a larger prospective and contemporary regional cohort.

IVC and Lung Ultrasound B-lines Guided Decongestion in Critically Ill ESKD Patients With Heart Failure

The objectives of this trial are to determine whether, in critically ill ESKD patients randomization to fluid removal guided by lung and inferior vena cava ultrasound, compared to standard care, leads to Improved pulmonary congestion (primary outcome); and safety (secondary outcome) in the short-term.

The Microcirculation, Dialysis Modality and Sequestered Salt

The aim of this clinical trial is to investigate the effect of 5 different dialysis treatments (combinations of dialysis mode and dialysis fluid sodium content) on the microcirculation (MC) and sequestered sodium content (SSC) in adult prevalent end-stage kidney disease (ESKD) patients treated with hemodialysis (HD) or hemodiafiltration (HDF). The main questions it aims to answer are: 1. What are the effects on the sequestered sodium content and microcirculation after 4 weeks of treatment with the following dialysis modes? * HDF with an expected zero diffusive sodium balance (Dialysate sodium concentration (DNa)= Plasma sodium concentration (PNa)) compared to * HDF with an expected diffusive sodium efflux (DNa \< PNa, difference 3 mmol/L) compared to * HD with an expected zero diffusive sodium balance (DNa = PNa) compared to * HD with an expected diffusive sodium efflux (DNa \< PNa, difference 3 mmol/L) compared to * Isolated ultrafiltration for 30 minutes followed by HD with an expected zero diffusive sodium balance (DNa = PNa) 2. Are the SSC and MC interrelated in this patient group? This study is a randomized cross-over trial. Participants will be subjected to the abovementioned dialysis treatment modes in random order.
