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.

The primary objective is to collect data to evaluate the biocompatibility of two types of blood circuit, already on the market.
NCT02084381
The medium cut-off dialysis membrane has been developed to provide a significantly extended molecular cut-off compared to conventional high-flux membranes. The medium cut-off membrane allows for a high permeability of molecules up to a molecular weight of 45 kDa and has a still limited permeability for albumin (68 kDa). The main goal of this project is the evaluation of the new, highly porous and selective dialysis membrane (MCO-Ci 400) for the treatment of patients with end-stage renal disease in hemodialysis mode and to study its potential to improve chronic inflammation.
NCT05105009
This is a two phase study. The first part will take place at the National Institute of Cardiology in Mexico, the second phase will be made in collaboration with the University of California San Diego and University of Minnesota. This is a non blind experimental study, 72 patients with different stages of CKD from the outpatient unit of the institute will be included. Each patient will receive a furosemide stress test of 1 mg/kg in non diuretic users and 1.5 mg/kg in diuretic users, in addition of 5 grams of creatinine oral intake, as well as Iohexol 5ml IV to measure GFR. After the intervention, blood and urine samples will be drawn at baseline, 60 minutes, 180 minutes, and 240 min. Urine output will be maintained during the study by the intravenous administration of Hartman's solution 1 -2 ml/kg body weight every hour, in addition to the volume of urine output in the preceding hour plus oral water ingestion as tolerated. Blood and urine will be analized to measure creatinine (blood and urine), then samples will be processed for measurement of furosemide (HPLC-Uv vis), indoxyl sulphate, p-cresol, hippurate, and iohexol (mass spectometry). The aim of this stiudy is to asses the differences between GFR and proximal tubule function.
NCT00358306
To understand how AKI (Acute Kidney Injury) leads to chronic kidney disease so therapies can be found to alter the progression of events thereby significantly impacting the long-term outcomes of children who develop AKI.
NCT01450670
A specifically formulated probiotic product comprised of defined and tested microbial strains may afford renoprotection in what has been generally called "Enteric DialysisTM". However, it is also referred to as enteric toxin reduction technology. Our hypothesis is to assess the potential benefits in devising a bowel-based probiotic formulation (Kibow® Biotics/RenadylTM) as a dietary supplement product for patients undergoing dialysis along with standardized care of treatment.
NCT03076528
Among patients with diabetes 35% suffer from chronic renal disease and may require dialysis or kidney replacement over time. Furthermore, in diabetics with end stage renal disease (ESRD) that require dialysis, the risk of foot complications and amputation is even more common, expensive, and devastating. Interestingly, even though incidence of foot ulcers in patients with dialysis has been reported to be same as with patients with history of foot ulcers; dialysis patients have significantly higher rate of foot amputation. The goal of this research is to incorporate an innovative virtually supervised non-weight bearing exercise in patients undergoing dialysis to reduce risk of fall and foot ulceration by enhancing lower extremity blood flow, joint perception and joint mobility. Diabetic patients on hemodialysis at Hamad Medical Company will be recruited and will be randomized to either intervention (IG) or control (CG) group and followed for 6 months. The intervention group will take part in a 4-week non-weight bearing exercise program twice per week at the hemodialysis clinic under the supervision of a qualified research staff member. This intervention includes interactive game-based exercises including repetitive ankle and foot movements. Wearable sensors will provide real-time visual/auditory feedback from foot and ankle position and allowed perception of motor-errors during each motor-action. The control group will be instructed to complete a supervised foot and ankle exercise without using sensor technology. Changes in balance, gait, and physical activity, incidence of foot problems will be compared pre- and post-intervention. In addition, the incident of falls, foot ulcers, and limb amputation up to 6 months post intervention will be documented. Investigators hypothesize that patients receiving sensor-based exercises will benefit more compared to group receiving conventional non-technology training in terms of improving functional performance and reducing incidence of foot problems, falls, and limb amputation.

NCT03202212
On line haemodiafiltration (OL-HDF) has been shown to improve intra-dialytic hemodynamics and cardiovascular outcomes. Several potential candidates of these beneficial effects have been explored. The aim of this study was to investigate the impact of mixed OL-HDF (mOL-HDF) on different circulating mediators of vascular dysfunction.
NCT01225458
The trial is a multicenter, prospective, randomized, open study. A total of 500 elderly patients aged over 75 years with renal insufficiency stage 5 will be included in the study after signed informed consent. Patients will be randomized 1/1 in two arms : 250 patients in the "exclusive nephrology follow-up" arm will continue their usual follow-up; 250 patients in the "geriatric follow-up" arm will have both their usual nephrology follow-up and a geriatric follow-up. The aim of the study is to determine if a systematized gerontologist evaluation delay the occurrence of a composite primary endpoint : death, dementia, depression and severe dependency. The hypothesis is that the functional and vital prognosis of a patient with renal insufficiency depends not only on common and classical factors but also on cognitive and psychological functions and dependence, particularly in elderly patients.
NCT01890811
Weight loss commonly occurs in patients with chronic kidney disease (CKD), negatively influencing their quality of life, treatment response and survival. Loss of muscle protein is generally a central component of weight loss in CKD patients but patients also have reductions in fat mass and bone density, independent of the severity of the disease state. Attempts to reverse weight and muscle loss in CKD and improve nutritional status by nutritional supplementation have been unsuccessful and there are currently no approved therapies. Purpose of this study is to provide detailed insight in disease related gut function by obtaining information on gut permeability, digestion and absorption of glucose, fat and protein in CKD patients compared to matched healthy controls. Additionally, to examine whether protein and amino acid metabolism is disturbed in CKD patients compared to healthy controls. This will provide required information that will lead to implement new strategies to develop optimal nutritional regimen in order to enhance nutritional status, quality of life and survival in relation to kidney disease.
NCT02065076
The purpose of this trial is to determine if sodium polystyrene sulfonate (SPS) is an effective treatment of mild hyperkalemia in chronic kidney disease patients followed at a pre-dialysis or nephrology outpatient clinic. Subjects will be randomized to one of two treatment arms: 30 g of placebo or SPS to be taken orally once daily for seven days. The change in serum potassium levels will be compared in both treatment groups. The proportion of subjects attaining normokalemia (3.5 to 5.0 mmol/L) after seven days of treatment will also be compared. Finally, side effects will be reported for each treatment arm.
NCT00788905
The purpose of the study to determine whether the level of inflammation may be decreased, the lifespan of red blood cells increased and the clearance of waste products in the blood improved through the use of the Allient System as compared to conventional hemodialysis.
NCT00153621
Among adults with Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS), Chronic Kidney Disease (CKD) has previously been reported to occur in approximately 10% of children with HIV-infection. The frequency of CKD, its causes, and its natural history in children and adolescents with HIV-infection have not been systematically studied, particularly in the era of new anti-retroviral medications. The primary aim of this study is to determine the how common pediatric HIV-infected individuals have evidence of persistent proteinuria and CKD.
NCT00009009
This study will examine the safety and effectiveness of renal (kidney) transplantation for HIV-infected patients with end-stage renal disease (kidney failure). Although kidney transplant is the best treatment for most causes of kidney failure, people infected with HIV are not offered this procedure because the immunosuppressive drugs (drugs that suppress immune function) required to prevent organ rejection could further impair the patient's already weakened immune system. This study will use a regimen of immunosuppressants designed to complement treatment for patients taking highly active antiretroviral therapy (HAART). HIV-infected patients between 18 and 60 years of age with renal failure who have not had any opportunistic infections for 5 years may be eligible for this study. Candidates will be screened with a medical history, physical examination, and blood and urine tests. Before the transplant procedure, participants will undergo additional tests and procedures, including blood studies, 24-hour urine collection, infectious disease consultation, tuberculin skin test, PAP smear for women, chest X-ray, brain and hip MRI studies and DEXA-scan to evaluate bone density. In addition, patients may undergo leukapheresis to obtain white blood cells for study. For this procedure, whole blood is drawn through a needle in an arm vein and passed through a cell separator machine. The white cells are collected for removal, and the rest of the blood is returned to the body through the same needle or another needle in the other arm. When a donor organ becomes available for transplant, the patient will receive three anti-rejection drugs-cyclosporine, mycophenolate mofetil and prednisone-to prevent organ rejection. Immediately after the surgery, HAART drugs will be stopped for 7 days until stable levels of the immune suppressants can be achieved. Then, HAART will be re-started and all medications will be adjusted to achieve adequate blood levels. Patients must stay in the local area 60 days after discharge from the hospital for monitoring. Frequent blood samples will be taken to monitor kidney function, viral load and CD4+ T cell counts. Follow-up visits will then be scheduled monthly for the first 6 months after transplant, then every other month for 1 year. Kidney biopsies will be done at the end of the first month, after 6 months, and yearly for 5 years. For the biopsy, a special needle is used to remove a small piece of kidney tissue for microscopic examination. The biopsies and blood tests are done to evaluate the immune response to the transplanted organ and to study how HAART interacts with the immune suppressing drugs.
NCT00074620
The study will look at the safety profile (unwanted effects) of the long-lasting anticoagulant PEG-hirudin (SPP200) and compare these unwanted effects to those of unfractionated heparin, commonly used in haemodialysis to avoid clotting of the graft and of the haemodialysis machine.
