Active clinical trials for "Kidney Diseases"

The goal of this research agenda is to improve the quality of end-of-life care by explicitly identifying values that will guide the decision-making process, with a particular emphasis on the role of ethnic, racial and cultural factors.

In this study, Investigators will conduct a prospective cohort study of dialysis patients by collecting research-quality information on patient characteristics, comorbid diseases and laboratory markers used in routine practice, as well as novel biochemical markers and genetic data. Investigators will utilize data from the cohort to test the independent relationship between biochemical and genetic markers and Fabry disease and other rare diseases.

This is a study with 2 parts. Part 1 comprises a visit to collect biological samples necessary for the molecular characterization of chronic kidney disease. Part 2 comprises an observational period of 5 visits over a period up to 8 weeks. During Part 2, baseline tests will be conducted, and urine will be collected approximately every 2 weeks for 8 weeks. Patients may participate in Part 1, Part 2, or both, and will be followed for up to 1 year consisting of data collection from the patient's medical records and home collection of urine samples every 4 months.

This is a single patient, single center study evaluating if administration of pan-genotypic DAA therapy on day 3 (+/- 2 days) post-kidney transplant prevents the transmission of hepatitis C virus infection from an HCV-positive donor kidney to an HCV-negative recipient.

An observational study to describe the treatment of anaemia in patients with chronic kidney disease, who are receiving dialysis treatment at selected study centres in South Africa.

Observation of humoral and cellular immune response after additional dose vaccine with different COVID-19 vaccines in ESKD patients in hemodialysis therapy.

This is a prospective cross-sectional, observational, single-center study of Alport patients, in which a single, first morning voided urine collection will be acquired and used to validate assays of urine biomarkers that reflect changes in glomerular protein filtration barrier function. The purpose of this study is to identify biomarkers indicative of changes in glomerular filtration function that occur during the course of proteinuric renal diseases such as Alport nephropathy.

There are substantial data demonstrating increased endothelial dysfunction, inflammation and oxidative stress in patients with Autosomal dominant polycystic kidney disease (ADPKD), the association between serum uric acid level and endothelial dysfunction has not been elucidated yet in these patients. Therefore, in this study, the investigators aimed to examine the relationship between the uric acid level and the ED in normotensive ADPKD patients with preserved renal function.

This study will collect white blood cells or plasma (the liquid part of the blood), or both, from healthy volunteers and from patients with rheumatic or kidney disorders for research purposes. Rheumatic disorders involve abnormalities of the immune system, the body s defense against disease. The immune system consists of white blood cells such as lymphocytes and monocytes, which produce substances such as antibodies and cytokines. White cells and plasma will be collected through a procedure called apheresis (described below). Healthy volunteers and patients with confirmed or suspected rheumatic or kidney disease who are 18 years of age or older may be eligible for this study. Patients must be participating in a current protocol of the National Institute of Arthritis and Musculoskeletal and Skin Diseases or the National Institute of Digestive, Diabetes and Kidney Diseases. All candidates will be screened with a history, physical examination, and blood tests for hepatitis B and C and HIV infection. Women of childbearing age will be tested for pregnancy. Routine blood tests will be done in all volunteers, and in patients where needed. Pregnant women and people who test positive for hepatitis or HIV may not participate. Participants will undergo apheresis to collect lymphocytes, monocytes, or plasma from the blood. For this procedure, a needle is placed in a vein in the arm. Blood flows from the vein through a tube (catheter) into a machine that spins the blood, separating it into its components. The required cells or plasma are extracted, and the rest of the blood, including the red cells and platelets, is returned to the body through the same needle or through a second needle placed in the other arm. Cells collected from volunteers will be used in studies comparing the number and function of similar cells from patients with rheumatic diseases, focusing on the differences in number and function of the cells in health and disease. Components collected from patients will be used only for studies described in the protocol in which they are currently enrolled. ...

Aim 1: Determine if there is an association between the APOL1 risk variants and allograft survival and function in African Americans Aim 2: Determine if there is an association between the presence of APOL1 risk variants in an African American kidney transplant recipient and the risk of recurrent disease Aim 3: Investigate mechanisms of APOL1 associated kidney disease by prospectively following African American kidney transplant recipients throughout their clinical course.
