Active clinical trials for "Kidney Diseases"

Chronic kidney disease (CKD) has become a global public health priority over the past few decades, affecting 10-12% of the adult population and has received increasing attention. Sarcopenia describes a generalizes degenerative skeletal muscle disorder involving the loss of muscle mass, muscle function and/or physical performance. Indeed, Sarcopenia is a condition with many causes and it can be considered "primary sarcopenia" when no other cause is evident but ageing. While in the clinical practice, it also occurs in patients with chronic diseases, such as chronic kidney disease, which can be considered "secondary sarcopenia". Notably, the occurrence of sarcopenia in CKD patients is not only related with ageing, the accumulation of uremic toxins, inflammation, insulin resistance, malnutrition and oxidative stress also contribute to the muscle depletion. Moreover, sarcopenia increased risk of falls and fractures, impaired ability to perform activities of daily living, disabilities, loss of independence and increased risk of death. Hence, it is of great significance to prevent the occurrence and development of sarcopenia in patients with CKD. The purposes of this project were to investigate the prevalence of sarcopenia, further explore the risk factors for sarcopenia and detect the relationship between sarcopenia and outcomes in CKD patients.

This is a longitudinal observation of kidney function, immune system and gut microbiota before and 24 weeks after a live kidney transplantation conducted in donor and recipient pairs living in the same household. Outcome measures include kidney function, body composition, blood pressure, gut microbiome composition, metabolomics and immune cell states.

Patients with high blood pressure (hypertension) and chronic kidney disease are at an increased risk of developing heart disease and strokes. Part of this risk is due to changes in the structure and function of the blood vessels throughout the body. It is thought that reducing high blood pressure and treating chronic kidney disease improves the structure and function of blood vessels but information on this is limited. Optical coherence tomography (OCT) is a method of looking at the blood vessels at the back of the eye. It is a simple, quick and non-invasive test that you may have previously had during a visit to the optician. The purpose of the study is to ascertain whether OCT is able to detect changes in the eye's blood vessels in patients with hypertension and chronic kidney disease compared to healthy individuals and also to see if any differences seen improve with treatment.

With the rapid increase of diabetic nephropathy worldwide, type 2 diabetes mellitus(DM) is the leading cause of end-stage renal disease(ESRD). Pathological types of diabetic kidney disease(DKD) could be mainly divided into diabetic nephropathy（DN）and non-diabetic renal diseases（NDRD）. There are no accurate renal biopsy indications and standardized operation procedures for type 2 diabetic nephropathy. The clinical stages of type 2 diabetic nephropathy still referred to the Mogensen stage of type 1 diabetic nephropathy. Thus, our study aim to clarify the differences in clinical phenotype between type 2 DN and type 2 NDRD, analysis the correlation between clinical and pathological features, and offer the criteria for clinical staging and prognosis.

This is a retrospective, multinational, non-interventional, observational study. A series of cohort studies will be conducted to assess the prevalence of undiagnosed stage 3 CKD in each region. The study will also assess the current state of CKD management in patients with undiagnosed CKD

This is a prospective, multi-center, observational study that will enroll patients receiving dialysis (hemodialysis or peritoneal dialysis) or patients with kidney transplantation who will be vaccinated against COVID-19.

Interdialytic weight gain determines how much fluid (ultrafiltration) has to be removed during each hemodialysis session. High ultrafiltration volumes stress the organism and lead to a higher risk of death. Thirst is the main driving factor of interdialytic weight gain, and thirst is mainly driven by salt intake, molecules that increase blood tonicity (such as sugar in diabetics) and fluid loss (such as in dehydration and blood loss). It has been speculated that fluid loss during hemodialysis could increase the sense of thirst immediately following dialysis, but this statement requires further evidence.

The current trial is designed to evaluate how the results of KidneyIntelX test impacts on the clinical management of type 2 diabetes patients identified as increased risk for rapid kidney function decline within 5-years.

In 2005, The University of Alabama at Birmingham established a NIDDK-funded, interdisciplinary center of excellence in PKD-related research, with specific emphasis on recessive PKD. In the previous Core Center award period, we developed a Core Resource to capture clinical and mutational data for ARPKD patients ("Core A: ARPKD Clinical and Genetic Resource", NCT00575705). However, studies in the last several years have demonstrated that ARPKD and other single gene disorders characterized by renal cystic disease and extra-renal phenotypes share numerous pathogenic features. In the current competitively- renewed Center, we have expanded this Core resource to include other hepato/renal fibrocystic diseases. Goals for the Core A: The Hepato/Renal Fibrocystic Diseases Translational Resource are: - Clinical Database: • Expand our comprehensive Clinical Database to include information from all patients who meet the inclusion criteria for hepato/renal fibrocystic diseases. - Mutational Database: Test children with ARPKD and other hepato/renal fibrocystic disease to identify genetic mutations, establish a DNA bank for patients with hepato/renal fibrocystic diseases and develop a Mutational Database. This Database will be capable of linking clinical and mutational information via a unique identifier in a searchable format to facilitate genetic research (e.g. genotype-phenotype correlations, new disease gene studies, and modifier gene studies), translational studies, and clinical trials. 3- Tissue Resource: Much of the research that is performed on diseases of the kidney, including recessive genetic diseases, requires human tissue from both affected as well as non-affected (controls) individuals. In this Core Resource, we are establishing an independent tissue resource which would supply investigators throughout North America with samples of hepato/renal fibrocystic disease affected tissues for studies of these disorders. 4- Educational Resource: Expand our multi-media, web-based resource to provide a reliable up-to-date, and comprehensive informational resource for ARPKD and Hepato/Renal Diseases families, their physicians, and genetic counselors. All the information regarding participation in "Core A: The Hepato/Renal Fibrocystic Diseases Translational Resource" is available at: http://www.arpkdstudies.uab.edu/.

The uremic syndrome is mainly related to the retention of a host of compounds, due to altered glomerular filtration and other factors of renal dysfunction, e.g. tubular secretion. Uremic retention solutes are arbitrarily subdivided in three different categories according to their physicochemical characteristics and their subsequent behaviour during dialysis: (i) the small, water-soluble, non-protein bound compounds, (ii) the larger middle molecules, mainly peptides and (iii) the small protein-bound compounds (1). Although direct proof is lacking, several lines of evidence indicate that albumin is the most important carrier protein. Removal of protein bound uremic retention solutes is limited. The Prometheus® system fractionates blood into plasma and cellular components, using an albumin-permeable polysulfon filter (AlbuFlow®) with a specially designed sieving coefficient curve (1.0 for 2-microglobulin, >0.6 for albumin, <0.3 for IgG, <0.1 for fibrinogen and <0.01 for IgM). Due to the high sieving coefficient of the filter for large molecules (i.e. cut-off at about 250 kD) molecules up to the size of albumin (69 kD) easily pass from blood into the secondary circuit which is filled with isotonic sodium chloride solution, whereas larger molecules like fibrinogen (340 kD) cannot pass through the filter. In the secondary circuit the filtered plasma with the albumin-bound toxins flows through one or two adsorbers in a row with maximized adsorption capacity for putative liver toxins that are directly adsorbed ('fractionated plasma separation and adsorption' or FPSA). The purified plasma is then returned to the blood side of the albumin filter. In order to eliminate water-soluble toxins, blood thereafter undergoes hemodialysis using a conventional high-flux dialyser. We hypothesise that removal of protein bound uremic retention solutes can be improved by FPSA as compared to standard hemodialysis.
