Active clinical trials for "Kidney Failure, Chronic"

The Canadian Australasian Randomized Trial of Screening Kidney Transplant Candidates for Coronary Artery Disease (CARSK) will test the hypothesis that eliminating the regular use of non-invasive screening tests for CAD AFTER waitlist activation is not inferior to regular (i.e., annual) screening for CAD during wait-listing for the prevention of Major Adverse Cardiac Events. Secondary analyses will assess the impact of screening on the rate of transplantation, and the relative cost-effectiveness of screening.

Urinary tract infection (UTI) is the most frequently occurring serious bacterial infection in young children and accounts 5 to 14% of emergency department visits Formation of renal scarring in children has been associated with serious complications as hypertension, preeclampsia, and end stage renal failure in young age . So, this study aims to determine whether dexamethasone reduces the renal scarring in children will be treated with antibiotics for acute pyelonephritis. investigators propose to conduct a multi center, randomized, placebo-controlled, double-blind clinical trial, that will evaluate the efficacy of dexamethasone (0.3 mg/kg every 12 hours per day orally for 3 days) in preventing renal scarring in young febrile children (2 months to 14 years) with a first-diagnosed UTI. 120 Participants will be enrolled over a 3-year period from 6 sites.

Kidneys retrieved from deceased donors will be randomized for conventional perfusion (University of Wisconsin: UW) with or without supplementation of thiosulfate, a major H2S metabolite, and transpl anted thereafter. Recipient's renal function will be assessed prospectively to determine if thiosulfate improves allograft function.

The purpose of this study is to evaluate the safety and tolerability of TX200-TR101 and its effects on the donated kidney in living donor kidney transplant recipients. TX200-TR101 is a product made from a kidney transplant recipient's own immune cells, which are genetically modified and designed to help the transplant recipient's body accept their donated kidney and prevent their immune system from rejecting it.

The main objective is to assess the effects of chronic intradialytic physical exercise on myocardial remodelling and regional function.

This is a randomized, double-blind, placebo-controlled trial in de novo kidney transplant patients to determine if the addition of fingolimod (brand name Gilenya®, candidate name- FTY720) on the background of standard immunosuppression will prevent expansion of the interstitial compartment of the transplanted kidney. Interstitial expansion is the precursor of interstitial fibrosis and graft loss. The study will test the hypothesis that abgrogating the fibrogenic effects of both the RhoA and mTOR pathways with fingolimod will reduce structural damage in transplanted kidneys and possible subsequent transplant failure.

Chronic kidney disease (CKD) is a common disease affecting 10-12% of the adult population and characterize with high-risk cardiovascular morbidity and mortality with progression of CKD. Treatment with sodium-glucose cotransporter 2 inhibitors (iSGLT2) not only improves hyperglycemia and type 2 diabetes (T2D) but also results in body-weight loss, a reduction in blood pressure, and a decrease of cardiovascular events and progression of renal failure in both diabetes and non-diabetes patients.(Heerspink et al. 2020) Therefore, dapagliflozin is now associated with the inhibitors of the renin-angiotensin system to reduce kidney events. However, the mechanisms underlying the effects of dapagliflozin on the renal function remain unclear. When renal failure occurs, it impairs the removal of several metabolites called uremic retention solutes. If these retention solutes exhibit deleterious interferences with biochemical/physiological functions, they are referred to as uremic toxins as they can contribute to the manifestations of the uremic syndrome and are associated with a high cardiovascular morbidity and mortality and with progression of CKD. Many of the uremic toxins are not produced by the body itself but rather derived from gut microbiota metabolism such as the well-known trimethylamine-N-oxide (TMAO),p-cresyl sulfate (PCS), phenyl sulfate (PS), indoxyl sulfate (IS), and indole-3-acetic acid (IAA).The gut microbiota composition in a uremic context has been the subject of an increasing number of publications and majority of them confirm a decrease of gut microbiota richness and deep modifications.Recently, an animal study suggested that dapagliflozin, subtly improve the composition of the gut microbiota in mice with T2D and another preliminary clinical study didn't observe a modification in the fecal microbiome after dapagliflozin initiation.But in other study, empagliflozin significantly reshaped the gut microbiota after 1 month of treatment in T2D patients and be associated with shifts in plasma metabolites. Similarly, canagliflozin reduces plasma uremic toxins in a CKD mice model.However, it remains unknown whether treatment with dapagliflozin alters the gut microbiota in CKD patients without T2D; furthermore, the relationship between the gut microbiota, uremic toxins production and CKD-related beneficial effects of dapagliflozin remains elusive. Herein, the investigator will investigate the clinical benefits of dapagliflozin and possible associations between its renal function benefits and alterations in plasmatic gut microbiota-derived metabolites and the gut microbiota composition in non-T2D CKD patients. To this end, the investigator will conduct an observational clinical trial in non-T2D CKD patients with the primary aim of investigating dapagliflozin-induced compositional changes of intestinal gut microbiota.

Frailty and sarcopenia are modifiable risk factors for morbidity and mortality in patients with ESRD. Exercise is the recommended intervention to prevent frailty and sarcopenia, however, many clinical trials have shown limited clinical improvement in muscle mass and physical function. We propose that mitochondrial dysfunction is one of the deterrents to the effectiveness of the exercise. We plan to evaluate the additive effect of HIIT and CoQ10, a mitochondrial-targeted therapy, on mitochondrial function and physical performance. Understanding the interplay among CoQ10, exercise, and mitochondrial function will identify novel mechanisms to improve the efficiency of exercise. This will also serve to prevent frailty, sarcopenia, and muscle dysfunction in patients with ESRD.

The primary study objective is to evaluate the benefit of the Sirolimus eluting Collagen implant (SeCI; Sirogen), a single dose prophylactic treatment delivered intraoperatively at the time of surgical creation of an arteriovenous fistula for hemodialysis vascular access.

The use of contrast media (CM) poses a risk of post-contrast acute kidney injury (PC-AKI), especially among patients chronic kidney disease (CKD). International guidelines recommend intravenous (IV) hydration with isotonic 0.9% NaCl for three-four hours pre-contrast and four-six hours post-contrast. Recent studies have proven that oral hydration or no hydration is non-inferior to IV hydration in patients with mild to moderate CKD (eGFR 30-60 mL/min/1.73 m2). However, no randomized controlled trials have evaluated alternative hydration methods against the guideline-recommended hydration protocol for the prevention of PC-AKI in high-risk patients with severe CKD (eGFR < 30 mL/min/1.73 m2). Thus, the main focus of this trial is to evaluate IV hydration vs. oral hydration for their efficacy to prevent of PC-AKI in patients with severe CKD, who are scheduled for an elective contrast-enhanced CT-scan (CECT) with IV contrast-administration. Our research hypotheses consist of the following: Oral hydration with bottled tap water is non-inferior to IV-hydration with isotonic 0.9% NaCl as renal prophylaxis to prevent PC-AKI in patients with severe CKD referred for an elective IV CECT. NGAL and cfDNA are early and precise plasma and urinary biomarkers of PC-AKI with excellent diagnostic and prognostic accuracy for PC-AKI, dialysis, renal adverse events, hospitalization, progression in CKD-symptoms, and all-cause mortality.
