Active clinical trials for "Renal Insufficiency"

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.

Renal failure is present in 40% of heart failure patients, and is one of the main comorbidities of heart failure. Follow-up with pulmonary artery pressure (PAP) monitoring has shown a reduction in mortality and frequency of hospitalization in patients with heart failure alone in the CHAMPION trial. Patients with New York Heart Association class III heart failure and a hospitalization in the previous 12 months were included in that study. They benefited from the "CardioMEMS™ HF" device with a sensor implanted in the pulmonary artery to measure PAP. According to that study, the information led to more precise and early adaptation of therapy by avoiding the onset of heart failure symptoms and reducing the number of hospitalizations. However, in that study, patients with impaired renal function (Glomerular Filtration Rate<25 mL/min/1.73m2) were excluded, limiting the indication for treatment in those patients, and the evolution of renal function during the study was not reported. Patients with heart failure AND advanced renal failure are defined as having a cardio-renal syndrome, with strong interaction between these 2 organs. In the event of predominant right heart failure, they may require treatment by renal replacement or dialysis. There seems to be a link between high venous pressure, renal repercussions and the need for dialysis. Additional follow-up data in this clinical situation are needed to confirm this link and to suggest the interest of continuous PAP monitoring to improve the management of these patients with cardio-renal syndrome with severe renal impairment defined by a Glomerular Filtration Rate< 30 ml/min/1.73m2 (KDIGO Cardio-renal 2019). This pilot study aims to evaluate how tolerable the "CARDIOMEMS™ HF" device in patients with cardio-renal syndrome and obtain the first information on the relationship between cardiac hemodynamics and renal function in this population.

This study aim to investigate the protected effects of short-term use of dapagliflozin (administered within 3 days after procedure) in CKD patients after coronary angiography or percutaneous coronary intervention, as well as observed the incidence of CIN.

This phase II study, 24-week, double-blind, study evaluated Eefooton's safety and efficacy for patients with CKD stage 3 to 4 Not on dialysis.

Various forms of organisation in the care of patients with akute kidney injury are investigated. In this prospective study the investigators compare the effect of usual care with the effect of intensive care. Primary endpoint is the development of cardiovascular events ("major adverse cardiovascular events" "MACE").

Diabetes after kidney transplantation is a frequent complication, the incidence of which varies from 7 to 45% depending on the studies and on the diagnostic criteria used. Post-transplant diabetes is an early complication, most often occurring in the first month after transplantation. In addition to the additional health costs generated by the appearance of post-transplant diabetes, the risk of graft loss is increased by 60% and the overall mortality risk by 90%. Similarly, the development of glucose intolerance after transplantation is associated with higher mortality. Tacrolimus treatment is therefore currently one of the most important risk factors for diabetes at the time of transplantation. Indeed, several in vitro and in vivo animal studies have shown that tacrolimus alters pancreatic endocrine function. In the final stage, this cellular toxicity leads to diabetes, most often diagnosed on the rise in capillary or venous blood sugar levels after transplantation. This diabetes often requires hypoglycemic treatment with insulin or oral anti-diabetic drugs. for a variable period. The pro-diabetogenic effect of tacrolimus is sometimes irreversible, justifying preventive treatment. No clinical studies have looked at "sub-clinical" changes in insulin secretion or insulin resistance under tacrolimus prior to the onset of diabetes. The static indices HOMA-β% and HOMA-IR (Homeostasis Model Accessment of insulin resistance) make it possible to estimate insulin secretion and insulin resistance in fasting patients respectively, while the oral glucose disposition index (IDO) makes it possible to study insulin secretion and action dynamically (after a 75 g glucose load), and are calculated as follows: HOMA IR= Fasting blood glucose (mmol/L) x Fasting insulin (mU/L)/ 22.5 HOMAβ% = 20 x fasting insulinemia (mU/L) / fasting plasma glucose (mmol/L) - 3.5 IDO = (delta insulinemia T30-T0/ delta blood glucose T30-T0)/insulinemia T0 These indices have already been studied in dialysis patients (diabetic and non-diabetic) and may allow a more detailed study of pancreatic response and insulin resistance under tacrolimus in patients prior to renal transplantation. Determining the "pancreatic response" to tacrolimus in patients prior to transplantation would prevent diabetes by adapting immunosuppressive treatment and post-transplant screening modalities in the event of pre-transplant subclinical abnormalities identified in our study. The development of tacrolimus-induced diabetes in pre-transplantation in our study will be a contraindication to tacrolimus at the time of transplantation and ciclosporin therapy will be preferred.

The goal of this clinical trial is to improve communication among clinicians, patients with memory problems, and their family members. We are testing a way to help clinicians have better conversations to address patients' goals for their healthcare. To do this, we created a simple, short guide called the "Jumpstart Guide." The goal of this research study is to show that using this kind of guide is possible and can be helpful for patients and their families. Patients' clinicians may receive a Jumpstart Guide before the patient's clinic visit. Researchers will compare patients whose clinician received a Jumpstart Guide to patients whose clinician did not receive a guide to see if more patients in the Jumpstart Guide group had conversations about the patient's goals for their healthcare. Patients and their family members will also be asked to complete surveys after the visit with their clinician.

The study is a prospective, non-randomized early feasibility study intended to evaluate the safety and performance of the JuxtaFlow System (also known as the JuxtaFlow Renal Assist Device (RAD)) in participants with pre-existing renal insufficiency who are undergoing cardiac surgery.

The main aim of this study is to find out how the body processes 1 dose of TAK-279 (pharmacokinetics) in participants with kidney problems compared to participants without kidney problems. Other aims are to check for side effects from TAK-279 and to learn how well participants tolerate 1 dose of TAK-279. The participants will need to stay at the clinic for 11 days.
