Active clinical trials for "Renal Insufficiency"

Patients who have had a previous allograft failure represent a major problem for transplant centers as they are highly-human leukocyte antigen (HLA) sensitized and unlikely to receive another transplant without significant desensitization. This single center, phase I/II, open label single-arm exploratory study focuses on enrolling twenty patients (ages 15-75) who will begin desensitization therapy to achieve HLA incompatible (HLAi) renal transplantation. Patients who qualify will receive up to 6 doses of clazakizumab 25 mg monthly pre-transplantation. If patients receive an HLAi transplant during the study, the participants will continue to receive another 6 monthly doses of clazakizumab 25 mg, followed by a 6 month protocol biopsy. Patients will continue another 6 doses over 6 months if improvements are seen after the 6th dose of clazakizumab. Patients who develop evidence of persistent allograft dysfunction may have non-protocol biopsies for cause. Patients who receive 12 doses of clazakizumab post-transplant will receive a 12M protocol biopsy.

Rationale: Sodium glucose co transporter 2 (SGLT2) inhibitors are a relatively new class of agents, originally developed as oral antihyperglycemic drugs. SGLT2 inhibitors are clinically available since 2012 for the treatment of patients with diabetes mellitus type 2. Later, SGLT2 inhibitors appeared to have also specific reno- and cardioprotective effects. Remarkably, the trials that have been performed thus far excluded patients with an eGFR below 25 mL/min/1.73m2 at inclusion, prevalent dialysis patients, and kidney transplant recipients. This is unfortunate, because especially these patients are at high risk of reaching kidney failure requiring dialysis, cardiovascular complications and mortality, whereas there are only few proven effective therapies. There is emerging evidence from experimental studies and post hoc-analyses of randomized clinical trials that SGLT2 inhibitors may also be effective in preventing cardiovascular and mortality outcomes in these patients with severe CKD, including patients receiving dialysis or living with a kidney transplant. For instance, subgroup analysis of the DAPA-CKD trial comparing 624 patients with an eGFR<30 to the remainder of the trial population with better kidney function, demonstrated that the efficacy of the SGLT2 inhibitor dapagliflozin in reducing cardiovascular, heart failure and renal outcomes persisted in the population with impaired kidney function. Furthermore, in the DAPA-CKD trial patients continued to use dapagliflozin or placebo when dialysis was initiated. In the subgroup of patients who initiated dialysis, dapagliflozin was associated with a relative risk reduction for mortality of 21%. Finally, in kidney transplant recipients, SGLT2 inhibitors have been shown to be effective in lowering HbA1c, body weight, blood pressure and stabilize kidney function, and these agents were well tolerated and safe. Taken these findings together there is a sound rationale to study the long-term reno- and cardioprotective efficacy and safety of SGLT2 inhibitors in patients with severe CKD. There are two cardiac sub-studies: the cardiac MRI substudy and the echocardiography sub-study. The echocardiography sub-study is referred to as the "SGLT-2-inhibitors to Target Heart Failure in Peritoneal Dialysis" (STOP HF in PD) study. In STOP HF in PD the effect of dapagliflozin on cardiac function will be assessed in a subset of 100 patients treated with peritoneal dialysis.

This study is intended to be a single-site, prospective, randomized, double-blinded study that intends to enroll a total of 60 patients with severe renal impairment undergoing surgery with general endotracheal anesthesia at Parkland Hospital. Patients will be randomized to receive either neostigmine (for reversal of cisatracurium) or sugammadex (for reversal of rocuronium). A standardized anesthetic protocol that is usual and customary for the type of operation the patient is having will be provided to the anesthesia teams of enrolled subjects. The remainder of the anesthetic care of the subject will not deviate from the standard of care. All patients will be monitored with continuous pulse oximetry postoperatively for 24 hours.

Approximately 50% of patients in the intensive care unit (ICU) develop acute kidney injury (AKI) and more than 10% need dialysis. There is no treatment for AKI. Care is aiming for optimization of circulation and blood flow to the kidneys and avoiding nephrotoxic agents. There is conflicting data concerning whether early or late dialysis is harmful for the kidneys. No one has examined the physiological changes in the kidney when starting dialysis and which blood pressure that leads to most optimal physiological conditions for the kidneys during dialysis. In this descriptive study of 20 ICU patients suffering from AKI we aim to investigate renal physiology when starting continuous renal replacement therapy (CRRT) and also at different target blood pressures using retrograde renal vein thermodilution technique. In parallel we will also investigate and validate this invasive method with contrast enhanced ultrasound of the kidneys.

Gastric Bypass followed by renal transplantation is superior to medical management followed by renal transplant for patients with severe obesity and renal failure.

Guidelines recommend oral anticoagulation with vitamin K antagonists for atrial fibrillation whenever the CHADS2VASC score is superior or equal to 2. As there are no specific guidelines for the hemodialysis patients with atrial fibrillation, the general guidelines apply. However, several retrospective studies suggest that these patients do not benefit from the oral anticoagulation regarding the risk of stroke and may even experience more bleedings and deaths. The aim of this prospective study is to prospectively compare the hemorrhagic and thrombotic risks of oral anticoagulation in comparison with no anticoagulation in hemodialysis patients with atrial fibrillation.

Computer tomography (CT) is the primary imaging option for acute abdominal pain in adults. Intravenous (IV) contrast media is used to improve the CT quality. In patients with impaired renal function, post-contrast acute kidney injury (PC-AKI) has remained a significant concern. Modern retrospective studies have shown no association between worsened baseline renal function and IV-contrast CT. However, no randomised controlled trial has been done to conclude this. The INCARO (INtravenous Contrast computed tomography versus native computed tomography in patients with acute Abdomen and impaired Renal functiOn) trial is a multicentre, open-label, parallel group, superiority, individually randomised controlled trial comparing IV-contrast enhanced CT to native CT in patients with impaired renal function. Patients requiring emergency abdominal or body CT with eGFR 15-45 ml/min/1.73 m2 are included in the study. The primary outcome is a composite outcome of all-cause mortality or renal replacement therapy within 90 days from CT.

This study; It will be done to evaluate the presence of oxidative stress and its effects on lipid peroxidation products and antioxidant parameters after massage application and the possible effects of the appropriate massage protocol applied to the patients on oxidative stress in hemodialysis patients with restless legs syndrome.

The purpose of this study is to test the effect of the "Best Case/Worse Case" (BC/WC) communication tool on receipt of palliative care and intensity of treatment at the end of life, quality of life, and quality of communication for older patients with end-stage renal disease (ESRD) receiving outpatient care at ten nephrology clinics. The intervention was developed and tested with acute care surgical patients at the University of Wisconsin (UW) and is now being testing to see if the intervention will work in a different setting. The intervention will be tested with 320 older adults who have end-stage renal disease (ESRD) and are receiving care from a nephrologist enrolled in the study. Randomly assigned nephrologists within each site will receive the intervention (training to use the BC/WC tool) or to be in the waitlist control, meaning that they will not be offered BC/WC training until the end of the study, when all participants have been enrolled. Participants will be on follow up with surveys and chart review for up to two years after study enrollment. Caregivers will also be invited to participate and complete surveys.

The aim of this study is to learn about the safety of empagliflozin in dialysis patients as a preparation for a future large clinical trial. Empagliflozin has been approved by the Food and Drug Administration for the treatment of either type 2 diabetes, heart failure, or chronic kidney disease among patients not on dialysis. The use of empagliflozin has not been studied or approved among patients on dialysis for kidney failure because empagliflozin acts on the kidneys. However, recent experimental studies have indicated that empagliflozin may provide direct heart benefits. Some dialysis patients have substantial residual kidney function, which may be protected by empagliflozin. Participants will be given empagliflozin for three (3) months on top of the standard of care (usual medical care for participants' condition) and will be followed up until one (1) month after the last dose. The investigators will collect information about participants' general health, obtain blood, urine, and imaging studies, check home blood pressure, monitor home blood sugar levels, and ask health-related questions to assess the safety and potential benefits of empagliflozin over four (4) months, including one month before the three (3)-month empagliflozin treatment.
