Active clinical trials for "Renal Insufficiency"

Some patients who undergo cardiovascular surgery requiring cardiopulmonary bypass will develop a kidney injury following their surgery. The purpose of this study is to take a blood sample from patients before they have this type of surgery and then at nine time points after their surgery to test their plasma for a biomarker called NGAL and compare the NGAL levels to their creatinine levels. We hypothesize that NGAL is an earlier marker for kidney injury than creatinine.

The purpose of this study is to audit the effects of changing all hemodialysis patients from intravenous to subcutaneous administration of ESA's, to ensure that a cost-saving is achieved and that this does not occur at the expense of anemia control. The dose changes will occur according to usual clinical care of patients and not along a protocol.

The purpose of this study is to determine if analysis of urine samples for specific markers can predict transplant rejection in people who have received kidney transplants.

Monocentric, randomised, controlled and open study. Subjects will be included prospectively and consecutively and randomly assigned into two groups. Intervention group A will benefit a medication adherence support program during 12 months while intervention group B during 6 months only. Adherence will be monitored using an Electronic Monitoring system (EM, named MEMS®; Aardex Ltd.) during 24 months. At each pharmacy visit, the pharmacist will conduct a semi-structured interview in 15 minutes based on Fisher's sociocognitive model with the patients. A summary of the interview and the adherence graph will be send to the patient' health professionals.

A study is being carried out to evaluate the biological, technical and clinical/biological efficacy of this technique, the practice of which is standardized in the department, in order to evaluate our practices and to improve them if necessary. As part of this study, the investigators will ask all patients scheduled for this procedure to participate in this observational prospective study without changing usual practices.

Based on animal studies, it was found that administration of endothelial receptor antagonists before and after renal blood vessels clamp and release results in a significantly reduced renal function injury. On the basis of these results, we chose to divide the study population into 2 groups: control group that would be treated the standard accepted preventive treatment: intravenous injection of Mannitol, cooling of the kidney surface, compared to the treatment group that in addition would receive pre- and post-operative treatment of endothelial receptor antagonists (Ambrisentan (Volibris (10mg). To be noticed that the drug is recognized and is given as a primary indication for patients with pulmonary hypertension. The differences between the renal function and biomarkers for pre- and post-operative renal ischemic injury would be examined in order to disclose if the kidney injury of the treated group was indeed smaller. This information will enable us to protect the operated kidneys from the ischemic damage, especially in those patients with poor basic renal function.

The aim of the study is to assess if abnormal lipid levels in childhood could cause early damage of the inner layer of the vessels, the endothelium. Dysfunction of the endothelium is the first event in the development of atherosclerosis, is present at all stages of atherosclerosis and is potentially reversible in childhood. It has been suggested that dyslipidemia, via its detrimental effects on endothelium, could impair renal function. This study will assess the dysfunction of the kidneys in children with dyslipidemia.

Individuals with kidney failure are kept alive using dialysis machines designed to remove toxic substances and excess fluid from the blood. Standard dialysis is undertaken three times a week at a dialysis unit, supported by a team of specialist dialysis nurses (so called in-centre haemodiafiltration or ICHDF). Each session lasts approximately 4 hours, during which time the fluid and toxins which have built up since the last session of treatment are removed from the blood. The rapid removal of fluid that takes place using this technique often causes unpleasant symptoms such as cramps and dizziness, as well as a "hangover", which may last several hours. It can also cause problems with the heart in the long-term. In recent years, individuals requiring dialysis have been able to choose between standard ICHDF or having haemodialysis at home (HHD) using a convenient table top machine called NxStage System One. This device is used more frequently than in ICHDF and for shorter sessions. As a result, the amount of fluid removed during each session is less than with ICHDF. This may be beneficial to the heart, but may also make these individuals feel generally better, which may make them want to be more physically active. It may also reduce the time taken to recover from any symptoms experienced after dialysis. Over a 12 month period, markers of heart damage (using blood tests and scans of the heart) in patients receiving frequent HHD will be studied and the results will be compared with a group of patients receiving ICHDF. The study will also compare any symptoms they may have, how fit they are, how physically active they are and how well they sleep. In addition, the investigators will assess how well fluid balance is maintained in each group and measure the changes in their remaining kidney function during this time.

This is a proposal for a retrospective observational study of the safety of metformin use in patients with chronic kidney disease, compared to other commonly used diabetes drugs. It will be conducted using retrospective data from the New York City CDRN, Medicare administrate files, and New York State Medicaid administrative files, which will be linked and then deidentified prior to analysis.

This study is being conducted in order to assess the need for dose adjustment for elafibranor in participants with renal impairment. Pharmacokinetic parameters of elafibranor and its active metabolite (GFT1007) will be compared in severe renal impaired participants (eGFR<15mL/mn/1.73m^2) versus healthy participants after a single oral administration of elafibranor 120 mg
