Active clinical trials for "Kidney Diseases"

an observational cross-sectional study is done to calculate the electrolyte imbalance at different stages of chronic kidney disease at tertiary care hospital.

Renal transplantation is the optimal method of treatment for end stage kidney disease however median lifespan of a kidney transplant is around 15 years. Existing methods of measuring transplant function and structure from blood and urine markers are imperfect; renal biopsy is often performed but is invasive. Novel methods of investigating transplant function are therefore required and emerging renal MRI sequences including ASL and diffusion weighted imaging may yield helpful biomarkers. Investigators will recruit 20 patients in the first year after transplant and measure MRI biomarkers at three time points, with correlation to existing methods of measuring transplant function.

Since 2017, a revolution began in the departments of nuclear medicine, with the routine use of gamma-cameras with semiconductor. These gamma-cameras (which obtained the CE-marking in 2016), offer a technological breakthrough by providing an additional information. They allow "to quantify" for the 1st time in clinical routine conditions, the quantity of radioactivity, by means of a "SUVspect", in a volume of interest, while respecting the recommendations of best practice of the learned societies of French nuclear medicine (SFMN), European (EANM) and American (SNM), without injection of tracer nor acquisition or additional irradiation. The SUVspect is therefore an indicator of the quantity of tracer in a given volume of acquisition. Until now, the interpretation criteria of scintigraphies are based on the homogeneity of distribution of a tracer in the explored organ (for single organs such as the heart or the thyroid, for example) or in the asymmetry of distribution of the tracer (for the double organs, such as the kidney or the joints). This new gamma-camera allows to study the distribution of the radio-tracers in "list" mode, allowing to retrospectively reconstruct the images in various ways (for example, by modifying the size of the matrix of acquisition, the energy windows, the time of acquisition). Therefore, we can simulate and propose modifications in current procedures. Every patient referred to our department of nuclear medicine to undergo a scintigraphy with a tracer of nuclear medicine (with a marketing authorization) can, while benefiting from an examination by this gamma-camera, to be the object of this study, and to profit from this additional information. So, without changing the diagnosis or the usual care, we wish to take advantage of this additional information to improve the criteria of interpretation of our examinations. This possibility being new, there is no available bibliography (our department is the 5th department of nuclear medicine in Europe to equip itself with this large field-of-view gamma-camera CZT, the DNM 670, made by General Electric), while 2961 articles speak about the SUVmax (in PET) in Pubmed.

Genkyst is a regional cohort involving up to nephrologists working in private and public nephrology centers in the West of France. It registers clinical and molecular genetic data of all consenting patients with ADPKD from this area.

The REduction of rIsk for Contrast-Induced Nephropathy (REICIN) study is the largest prospective multicenter data base for CIN flowing coronary angiography (CAG) or percutaneous coronary intervention (PCI). The REICIN study has the potential to characterize contemporary CIN incidence, modified risk factors and prognosis, so that to identify strategiaes to reduce risk of CIN following CAG/PCI.

The primary objective of this study is to identify whether cardiovascular complication rates are lower in patients who participate in managed diabetes care, in comparison to provincial and national rates. This study will involve an electronic medical record (EMR) chart audit, augmented by a manual review of hospital and other pertinent medical records, as necessary.

To know the blood level of allopurinol in chronic kidney disease (CKD) patient.

Due to rising importance of cardiovascular disease before and after renal transplantation we have changed our standard diagnostic procedure and perform stress echocardiography and myocardial scintigraphy. We would like to monitor these results and the outcome of our patients.

The addition of an estimate value of glomerular filtration rate (GFR) per Modification of Diet in Renal Disease [MDRD] (LEVEY) equation is being included and reported on all routine chemistry panels in the experimental group. The control group is only having serum creatinine, the current standard of care, reported on routine chemistry panels.

The purpose of this study is to evaluate the urinary excretion and renal metabolism of vitamins, in particular vitamin B12 and folate, in relation to various renal conditions involving loss of renal function and/or proteinuria.
