Active clinical trials for "Kidney Failure, Chronic"

We believe that knowing characteristics of uremic pruritus is the foundation to investigate its pathophysiology and offer better skin care for patients with chronic kidney disease. We therefore conducted this cross-sectional study to evaluate the characteristics of uraemic pruritus.

The aim of this study is to determine the vascular condition of hemodialysis patients with toe pressure measurement, finger pressure measurement and measuring glycated and oxidated proteins by skin autofluorescence. Hypothesis: Lowering of finger pressure/toe pressure during hemodialysis, especially in whom with a arteriovenous fistula, may contribute to critical limb ischemia in the extremities.

This study will identify which regions on the genes, and genes themselves, may account for an increased risk of end stage renal disease (ESRD), that is, near-total loss of kidney function, for people of African American descent. Researchers will use a technique called admixture linkage disequilibrium (MALD) to study genomes, genetic material, in about 2,500 participants from two existing studies and participants who will serve as controls. ESRD disproportionately affects African Americans, who constitute 29% of all ESRD patients in the Medicare ESRD program. The disease can result from a variety of diseases, with diabetes as the leading underlying cause (44% of cases) and hypertension as the second leading cause (26%). The proportion of ESRD cases caused by diabetes has increased dramatically. Patients age 18 and older who are African American, who have ESRD, and who are participants of the FIND and CHOICE studies may be eligible for this study. FIND, or Family Investigation of Diabetes and Nephropathy, involves a multicenter study to identify susceptibility genes, that is, those with a risk, for diabetic and other forms of kidney disease. CHOICE, or Choices for Healthy Outcomes in Caring for ESRD patients is an ongoing study that identifies risk factors for cardiovascular outcomes in ESRD patients. The principle of mapping by MALD involves genetic variations that exist across populations. When mixing occurs between populations having different (heterogeneous) genes, the admixed offspring inherits chromosomes of distinct ancestry. However, over generations of mating, and recombination over several generations, originally large blocks of DNA from African ancestry have become part of smaller segments throughout the chromosome. The study will focus on risk alleles, that is, alternative forms of genes that carry a disease risk. Risk alleles are closely related to nearby ancestral gene markers found in a person. Patients will undergo a collection of blood and urine for genetic testing. Researchers are conducting separate analyses in this study. Case-control analysis of ESRD will consist of 1,150 participants from FIND and 250 from CHOICE. There will also be 750 control participants from FIND. For the case-control analysis of diabetic ESRD, there will be about 750 participants from FIND, 125 from CHOICE, and 750 controls from FIND. Finally, there is the quantitative trait analysis, which looks at the phenotype-meaning visible characteristics produced by the interaction of a person's genetic makeup with the environment. That analysis will involve 350 patients with diabetic nephropathy but not ESRD and 750 controls from FIND.

The purpose of this study is to assess health related quality of life and its predictors among chronic dialysis patients and to assess cognitive function using 3 different tests. (undergraduate medical student research project; not published)

Purpose The purpose of this study is to compare the economical impact and clinical parameters of short daily hemodialysis using the NxStage® System One hemodialysis device with thrice-weekly conventional in-center dialysis using a matched cohort from the US Renal Data System (USRDS) database.

To understand how AKI (Acute Kidney Injury) leads to chronic kidney disease so therapies can be found to alter the progression of events thereby significantly impacting the long-term outcomes of children who develop AKI.

This is a registry of data collected from patient records, both of those who have a condition which may require transplantation and those who have undergone transplantation of the liver, kidney and/or pancreas.

Coronavirus disease 2019 is a novel viral disease caused by the Severe Acute Respiratory Syndrome Coronavirus 2 virus. The original cases occurred in Wuhan, China, in December 2019 and rapidly spread to other areas worldwide, constituting a pandemic with unimaginable health and economic consequences. the World Health Organization elevated the disease to the category of a pandemic on March 11, 2020. In children, the reported mortality rates were far below 1%, while in people above the age of 70 years it was above 5% or higher. So, in this retrospective study, the investigators describe the clinical features and outcomes of children with chronic kidney diseases who were diagnosed with Severe Acute Respiratory Syndrome Coronavirus 2 infection at pediatric centers in Doha from 1st March 2020 till January 20th, 2022. This review looks into the literature on pediatric patients with chronic kidney diseases to verify whether they were more prone to developing more severe symptoms when diagnosed with Coronavirus disease 2019 compared to children without chronic kidney diseases and adults with chronic kidney diseases, and the Prevalence of COVID-19 infection between patients with chronic kidney diseases, and the role of COVID-19 infection in increasing the relapses and deterioration of chronic kidney diseases.

The purpose of this study is to facilitate coordination of transplant centers in North Carolina, South Carolina, and Georgia to share kidney transplant referral data in patients with End-Stage Renal Disease (ESRD) who are candidates for kidney transplantation.

The purpose of this study is to prospectively collect data on doses of Erythropoietic Stimulating Agents (ESA) and Intravenous Iron, and the markers of erythropoietic activity and iron status. These data will be used to derive mathematical models which will subsequently guide dosing of both agents, such that a desired therapeutic outcome is achieved in every patient, while minimizing patient exposure to both agents.
