Nicotinamide Riboside Supplementation for Treating Arterial Stiffness and Elevated Systolic Blood...
Vascular DiseasesKidney Disease2 moreRisk of cardiovascular diseases (CVD) is significantly elevated in patients with chronic kidney disease (CKD); however, this increased risk is only partially explained by traditional CV risk factors. Arterial dysfunction is an important nontraditional CV risk factor gaining increased recognition in the field of nephrology. This process is best represented, both physiologically and pathophysiologically, by increases in the gold standard measure of arterial stiffening, carotid to femoral artery pulse wave velocity (CFPWV), which reflects, in particular, increases in aortic stiffness. Aortic stiffening with CKD is mediated by structural and functional (increased vascular smooth muscle tone) changes in the arterial wall stimulated by oxidative stress and chronic low-grade inflammation. Caloric restriction (CR) is a promising strategy for prevention of CKD-associated arterial dysfunction and CVD. However, long-term adherence to chronic CR regimens with optimal nutrition is very difficult to achieve. Research has shown that boosting NAD+ bioavailability to stimulate SIRT-1, a "CR mimetic" approach, reduces CFPW and oxidative stress in old mice, and this lab recently took the first step in translating these findings in a study of adults with normal kidney function and elevated systolic blood pressure (SBP). The data found that supplementation with nicotinamide riboside, a natural, commercially available precursor of NAD+ and novel CR mimetic, increased NAD+ bioavailability and reduced CFPWV and SBP. A randomized, placebo-controlled, double-blind, single-site phase IIa clinical trial to assess the safety and efficacy of oral nicotinamide riboside (500 mg capsules 2x/day; NIAGEN®; ChromaDex Inc.) for 3 months vs. placebo for decreasing aortic stiffness and SBP in patients (35-80 years) with stage III and IV CKD is being proposed. It is hypothesized that treatment will reduce CFPWV and SBP, as related to increases in systemic NAD+ bioavailability and reductions in oxidative stress, and inflammation. Aim 1: To measure CFPWV (primary outcome) before/after nicotinamide riboside vs. placebo treatment; Aim 2: To measure casual and 24h-ambulatory SBP (secondary outcome) before and after treatment; Aim 3: To determine the safety and tolerability of treatment with nicotinamide riboside vs. placebo; Aim 4: To measure systemic NAD+ and NAD+-related metabolite concentrations, as well as circulating markers of oxidative stress, inflammation, and vasoconstriction factors before and after treatment.

A Study to Evaluate the Safety and Effectiveness of the InnAVasc Arteriovenous Graft for Hemodialysis...
End Stage Renal Disease (ESRD)Kidney Failure1 moreThe CSP-2002 study will evaluate the safety and effectiveness of the InnAVasc arteriovenous graft (AVG) when implanted in and used for hemodialysis in participants suffering from end-stage renal failure (ESRD). The InnAVasc AVG is implanted and used similar to other standard-of-care dialysis grafts currently on the market. However, the InnAVasc AVG has been uniquely designed to potentially allow for immediate needle access (same day as implant surgery as opposed to 2-4 weeks of waiting), to potentially reduce excessive bleeding from the graft after dialysis, and it may provide protection from improper or missed needle cannulation attempts.

Ferric Citrate and Chronic Kidney Disease in Children
Chronic Kidney DiseasesWe will conduct a 12-month, double-blind, randomized, placebo-controlled trial to assess the effects of therapy with ferric citrate (FC) on changes in intact FGF23 levels (iFGF23, primary endpoint) in 160 pediatric patients (80 in each of the two arms) aged 6-17 years of either sex with chronic kidney disease (CKD) stages 3-4 and age-appropriate normal serum phosphate levels. Participants will be randomized to one of the two groups: 1) FC or 2) FC placebo. Participants will be recruited from 12 core clinical sites.

An Exercise Facilitator to Activate Simple Training Programs in the Dialysis Center
Chronic Kidney Disease Stage 5 on DialysisLow physical activity levels and progressive poor functional capacity affect quality of life and clinical outcomes of Chronic Kidney Disease (CKD) patients. Interventions to prevent the functional decline associated with a sedentary lifestyle or to relief from deconditioning are crucial, considering the significant beneficial effects of exercise in all CKD patients, especially in End-stage Kidney Disease patients (ESKD). Unfortunately, physical and psychological barriers to exercise are present and physical activity management is not routinely addressed in the patient's care. For the first time the project aims to test the impact of the regular presence of an exercise specialist in the Nephrology Unit. This facilitator, evaluating capacity, motivation and preferences of each patient, will design tailored solutions and assess the related outcomes. Several design of training programs will be proposed to dialysis patients, that can choose the exercise option that best fits their needing. The study will determine the feasibility of the project, the patients' adherence and the effectiveness of the programs proposed to improve the patients' lifestyle.

Shared Decision Making for Choosing renAl Replacement Therapy in Chronic Kidney Disease Patients...
Chronic Kidney Disease Stage 5Shared decision making (SDM) is an approach where clinicians and patients make decisions together using the best available evidence. An understanding of the patient's treatment goals, the advantages and disadvantages of treatment options, and the likelihood of achieving the outcomes are important to patients. International guidelines recommend that all patients with chronic kidney disease (CKD) at pre-dialysis stage should be educated to improve their knowledge and understanding of their condition and to choose the options for renal replacement therapy (RRT). Despite these recommendations, pre-dialysis educations are often infrequent. Many patients feel unprepared. Wrong or insufficient understanding due to insufficient explanation of treatment can lead to negative emotions. This may lead to a situation in which the patient loses the opportunity to make patient's own choices, resulting in emergency dialysis or dialysis modality that is not suitable for patients. Therefore, this study aims to evaluate whether SDM has an effect on the choice of RRT among CKD patients.

Uric Acid Lowering Trial in Youth Onset T2D
Diabetic Kidney DiseaseHyperuricemia7 moreAdolescents and young adults with youth-onset type 2 diabetes (T2D) are disproportionally impacted by hyperuricemia compared to non-diabetic peers and youth with type 1 diabetes (T1D). In fact, 50% of males with youth-onset T2D have serum uric acid (SUA) greater than 6.8 mg/dl. The investigators also recently demonstrated that higher SUA conferred greater odds of developing hypertension and diabetic kidney disease (DKD) in youth with T2D over 7 years follow-up. Elevated SUA is thought to lead to cardiovascular disease (CVD) and DKD by inflammation, mitochondrial dysfunction and deleterious effects on nephron mass. While there are studies demonstrating beneficial effects of uric acid (UA) lowering on vascular health in the general population, there are no studies in youth-onset T2D. Youth-onset T2D carries a greater risk of DKD and CVD compared to adult-onset T2D and T1D. Accordingly, a clinical trial evaluating UA lowering therapies is needed in youth-onset T2D. Krystexxa (pegloticase), a uricase, effectively lowers SUA and therefore holds promise as a novel therapy to impede the development of CVD and DKD in youth-onset T2D. This proposal describes a pilot and feasibility trial evaluating the effect of UA lowering by pegloticase on markers of CVD and DKD in ten (n=10) youth aged 18-25 with youth-onset T2D (diagnosed <21 years of age) over 7 days. The overarching hypothesis is that pegloticase improves marker of cardiorenal health by lowering UA.

Pragmatic Randomised Trial of High Or Standard PHosphAte Targets in End-stage Kidney Disease (PHOSPHATE)...
Kidney FailureChronic1 moreDuring end-stage kidney disease, clinical guidelines suggest reducing elevated phosphate levels in the blood. However, the effect of lowering blood phosphate levels on important patient-centred outcomes has never been tested. This trial will evaluate whether compared to high levels, lowering blood phosphate levels would reduce death or major events due to heart disease, improve physical health, and be cost-effective.

Efficacy of a High-intensity Physical Activity Program on Renal Function in High Risk Patients With...
Type2 DiabetesDiabetic Kidney DiseaseType 2 diabetes is a chronic condition whose prevalence is increasing globally. Kidney disease is a key complication of diabetes and is among the most common cause of end-stage renal disease, requiring renal replacement therapy. It has been shown that the trajectory of renal function (estimated glomerular filtration rate - eGFR) is of great prognostic value for renal and cardiovascular endpoints in diabetic patients. However the clinical use of this prognostic marker is not associated to date with a clear therapeutic intervention, effective in patients with type 2 diabetes identified with this biomarker. In France, type 2 diabetes patients have twice less physical activity than non-diabetic persons. Recently, it has been published that physical activity was associated with an improvement of renal risk in patients with type 2 diabetes, recruited from the LOOK-AHEAD study. It was demonstrated that high-intensity physical activity (HIPA) can have several additional advantages over moderate-intensity, on blood pressure improvement, and cardiovascular risk profile modification. In addition, this procedure was shown to be safe in patients with high cardiovascular risk. We plan to perform a randomized intervention comparing a structured program of high-intensity physical activity (HIPA) vs standard recommendations for physical activity on renal function decline (primary outcome) and mortality, renal and cardiovascular endpoints, patients' safety and quality of life (secondary outcomes). Study participants will be patients with established type 2 diabetes and a high renal risk, identified by rapid renal function decline, defined as a eGFR slope below -5ml/min per 1.73 m2/yr. The intervention is planned to last for 2 years.
