NCT02889575
Acute Renal Failure (ARF) is defined by a severe, and usually reversible, glomerular filtration rate decreasing. Acute Tubular Necrosis (ATN) remain the major cause of ARF involving distress and destruction of tubular cells. This specific typology of ARF may evolve toward Chronic Renal Failure (CRF) concretizing a major public health issue. Predict the progression of ARF towards CRF appears essential. The investigators believe that the PIIINP and urinary NGAL biomarkers may constitute robust biomarkers of progression risk towards CRF.
NCT01366144
This phase I trial studies the side effects and the best dose of veliparib when given together with paclitaxel and carboplatin in treating patients with solid tumors that are metastatic or cannot be removed by surgery and liver or kidney dysfunction. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving veliparib together with paclitaxel and carboplatin may kill more tumor cells.
NCT07649083
Patients are randomly assigned to a study group. Depending on the study group, either an arteriovenous fistula or tunneled cuffed catheter (TCC) will be implanted, followed by continuous evaluation of the patients during the first year after initiating the vascular access. The evaluation includes statistical evaluation of all events, including loss of access, thrombosis, infection, loss of patency, increase in co-morbidities, e.g. congestive heart failure as well as quality of life. The implantation of the TCC is a standard procedure and it will be used only in accordance with the approved instructions of use on subjects who have signed an informed consent form. The surgery is a standard operation and it will be performed by specialized surgeons on subjects who have signed an informed consent form (No grafts will be used; implantation of a standard TCC, used at the Department of Nephrology). Both, an arteriovenous fistula or a TCC, will be used for routine chronic haemodialysis
NCT07198906
Acute renal failure after cardiac surgery is a common postoperative complication, affecting approximately 20% of patients. It is associated with an increase in short-term mortality and an increase in hospital stay; but is also associated with an increase in long-term mortality of up to 30% at 5 years, even if renal function recovers upon discharge. Its origin is multifactorial: intraoperative hypoperfusion, including hemodynamic variations related to extracorporeal circulation or bleeding, postoperative hypoperfusion related to cardiogenic or vasoplegic shock, ischemia-reperfusion phenomena leading to cell lysis or inflammation at the tubular level, inflammation and oxidative stress related to extracorporeal circulation, and hemolysis are the main causes. Hydro-sodium overload and associated venous congestion is also one of the etiologies of acute renal failure in post-operative cardiac surgery and is associated with increased mortality. The proposed pathophysiological mechanism is based on the decrease in renal tissue perfusion pressure due to the increase in venous pressure. In the extreme, the increase in pressure in the renal capsule could lead to true renal ischemia due to engorgement. This renal congestion can be diagnosed based on clinical signs, biological signs (such as NT-pro-BNP) or by monitoring by central venous pressure (CVP). However, these statistical tools have low diagnostic performance, and new tools based on ultrasound and Doppler are being developed. Indeed, alterations in venous flow in the renal, suprahepatic and portal veins, reflecting the increase in pressures there, are associated with the onset of acute renal failure in post-operative cardiac surgery.
NCT06001827

NCT07409532
The kidney is one of the most vital organs in the human body. Renal perfusion is primarily supplied by the renal artery, while the removal of metabolites and venous drainage are provided by the renal vein. Although anatomical variations may exist, the renal artery typically originates from the abdominal aorta. In patients undergoing liver transplantation, renal function may be affected by multiple factors. Impairment of renal function significantly influences postoperative mortality, morbidity, graft survival, and length of hospital stay. Intraoperative assessment of renal perfusion has traditionally relied on monitoring hourly urine output and serum renal function tests. However, these methods may be insufficient and delayed in evaluating renal function, particularly during clamping of the inferior vena cava for hepatic graft venous anastomosis. Although Doppler ultrasonography can provide information regarding blood flow, it does not offer direct insight into the adequacy of tissue perfusion. Near-infrared spectroscopy (NIRS) is a non-invasive technique that has gained increasing attention in recent years due to its ability to accurately assess tissue oxygenation. Based on the Beer-Lambert law, NIRS enables the measurement of tissue oxygen saturation without the need for invasive procedures. The technique requires no intervention and is not associated with known complications or adverse effects. NIRS is most commonly used in clinical practice to assess cerebral oxygenation via measurements obtained from the frontal region. The aim of the present study is to evaluate renal oxygenation using near-infrared spectroscopy and to determine whether this technique provides clinically useful information during the liver transplantation procedure.
NCT01682590
The purpose of this multicentric, randomized controlled trial is to assess whether the timing of renal replacement therapy initiation (early vs delayed) has an impact on mortality at 90 days in patients with severe acute kidney injury at the failure stage (according to RIFLE criteria) during the initial phase of septic shock.
NCT07390604
Lipoprotein-apheresis DFPP has been performed in patients with Lp(a) levels greater than 125 nmol/L. In this report, data will be presented on five hemodialysis patients with significantly elevated Lp(a) levels (\>200 nmol/L) who had a history of cardiovascular disease and notable thromboembolic events.
NCT05443321
Sub-optimal transfer of clinical information during inter-hospital transfer (IHT, the transfer of patients between acute care hospitals) is common and can lead to patient harm. To address this problem, the investigators will use key stakeholder input to refine and implement an interoperable health information exchange platform that integrates with the electronic health record and improves the reliability of and access to necessary clinical information in three use cases involving transfer of patients between sending and receiving hospitals with varying levels of affiliation and health record integration. The investigators will assess the effect of this intervention on frequency of medical errors, evaluate the use and usability of this platform from the perspective of those that interact with it, and use these results to develop a dissemination plan to spread implementation and use of this platform across other similar institutions.

NCT06056102
This research study is for people who have been waiting for a kidney transplant for at least one year, and who have a cPRA of 99.5% or higher. Having a cPRA of 99.5% or higher means that your immune system would reject 99.5% of kidneys available for transplant. The study will test whether new products called Chimeric Antigen Receptor T Cells (CAR T Cells), when given with chemotherapy, is safe and will reduce cPRA. The main study will last up to 2 years: Participants will have up to 30 clinic or hospital visits over a one-year period. If a transplant takes place, there will be 9 more visits after transplant. Long term follow up is required by the Food and Drug Administration (FDA) for 15 years after receiving CAR T cell. The primary objective is to evaluate the safety and feasibility of administering CART BCMA + huCART-19 following lymphodepletion, including determination of optimal tolerated regimen (OTR) and/or recommended phase 2 regimen, according to the incidence of dose limiting toxicity (DLT) in highly sensitized patients awaiting kidney transplant.
NCT00561483
Renal Compromise after treatment of decompensated heart failure with diuretics is not uncommon. The purpose of our study is to investigate the relationship between cystatin C and worsening renal function in this setting. Cystatin C is a biomarker produced at a constant rate by all cells that is a sensitive biomarker of renal function.Cystatin C and Plasma amino terminal proB-type natriuretic peptide (NT-proBNP) levels will be obtained at baseline and daily. Our goal is to enroll 100 subjects with an estimated 5 samples per each subject. The time course of changes in cystatin C in relation to serum creatinine levels over time will be plotted. Our hypothesis is that sequential changes in cystatin C levels following initial treatment with diuretic therapy in the setting of acute decompensated heart failure may provide early insight into cardio-renal compromise. Understanding the natural history and time course of the changes in sequential cystatin C levels may facilitate further studies to guide the judicious use of diuretic therapy in acute decompensated heart failure, and to predict the risk of subsequent development of worsening renal function. If serial testing of cystatin C can provide accurate assessment and prediction of worsening renal function, clinical applications of these observations can be evaluated in future prospective studies.
