Active clinical trials for "Kidney Diseases"

A study of the natural history of bone and mineral disease (BMD) in patients with end-stage renal disease before and after kidney transplantation

The aim of the study is to evaluate whether a low level of serum omentin-1 is associated with carotid atherosclerosis and mediated by inflammation.

Chinese herb nephropathy (CHN), a kind of kidney failure caused by Chinese herbs, may be related to the a component called aristolochic acid (AA). AA may form AA-DNA adducts and accumulate in the kidney and ureter and cause kidney failure and/or cancer Different enzymes have been reported to detoxify plant alkaloids or other components. Genes that regulate the production of these metabolic enzymes may affect the chance of CHN. By comparing the differences in the polymorphisms of these genes between patient with CHN and control, we may find the changes that play a significant genetic factors for CHN.

Inulin's usefulness as a diagnostic agent is based on the method of its elimination from the body. Inulin is biologically inert, unbound by plasma proteins, freely filtered at the glomerulus, and is neither reabsorbed, metabolized nor secreted by the kidneys. It is excreted almost entirely by glomerular filtration. Inulin clearance is considered to be identical to glomerular filtration rate (GFR).

The present study is to determine the ability of urinary total adiponectin and its isoforms excretion in the prediction of contrast induced nephropathy (CIN) in the patients undergoing PCI.

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.

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.

Due to their immunosuppressive therapy, solid-organ transplant (SOT) recipients bear a 10 to 100 times higher risk of human papillomavirus (HPV)-associated malignancies than healthy individuals. The objectives of this observational, non-interventional multi-national, multi-centre research project are to gain an insight into current HPV vaccination strategies and to investigate the immune response to different routinely administered HPV vaccines in European paediatric SOT candidates and immunocompromised transplant recipients, enabling patients at risk of vaccination failure to be identified.

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

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.
