Active clinical trials for "Kidney Diseases"

Fluid restriction is necessary among patients with chronic kidney disease. However, treatment adherence remains a challenge. Hence, this study determined the effects of a fluid distribution timetable on adherence to fluid restriction of patients with end-stage renal disease undergoing hemodialysis. This study used a single-blind, randomized-controlled pilot study design. Patients with end-stage renal disease were randomly-assigned using computer-generated sequences of randomly permuted blocks stratified according to sex to receive the fluid distribution timetable or standard care. Adherence to fluid restriction was measured using two indicators - thirst and interdialytic weight gain - and were compared using One-way RM-MANOVA and MANCOVA. Secondary outcomes included baseline patient demographic and clinical characteristics and were compared according to treatment allocation. Both groups were followed-up for four weeks, assessing outcome measures during the second hemodialysis session for each week.

The purpose of the study is to learn more about how treatment with vitamin D can affect iron metabolism and blood levels of two hormones that control iron levels, hepcidin and hemojuvelin in people with chronic kidney disease (CKD). Iron is an essential mineral which is a major component of proteins that carry oxygen in the blood. Problems with iron metabolism can lead to low blood levels (anemia), which can commonly happen in people with CKD. New research over the last decade has uncovered a new hormone called 'hepcidin', which is made in the liver and released into the blood. Hepcidin controls how much iron is in the blood by preventing the absorption of iron from food. Blood levels of hepcidin C are found to be high in people with CKD, and a recent small study in people with normal kidney function showed that treatment with vitamin D decreased hepcidin levels. Another protein, known as 'hemojuvelin', has been recently discovered and is also thought to control the amount of iron in the blood. The relationship between vitamin D and hemojuvelin has never been studied before. In this study, investigators would like to examine the effects of vitamin D on iron metabolism and blood levels of hepcidin C and hemojuvelin in individuals with CKD.

Anemia is a common complication of chronic kidney disease (CKD). In anemia of chronic kidney disease, patients suffer from low hemoglobin levels, which contribute to feelings of malaise and fatigue. The current accepted practice is often to administer erythropoietin-stimulating agents (ESAs), which act like the body's natural hormones to stimulate the production of red blood cells from bone marrow. Although ESAs are widely used in CKD, recent evidence suggests that they are not as safe as previously thought. In this study, we seek to test a decision aid to be used when a patient visits his or her nephrologist at Vanderbilt. The objective of the decision aid is to reduce patient confusion, improve their satisfaction with their care, improve their knowledge of kidney disease, and ultimately bring more clarity to patients about a controversial but ubiquitous drug. The decision aid will be about 1 page long and will include questions and information that might help the patient be more active and informed regarding the choice of a course of ESA therapy. We will ask patients to answer questions before and after their clinic visits regarding their satisfaction and confidence in their treatment and their knowledge of kidney disease; we will ask some of the same questions 3 months after the clinic visit. We will compare patients who are counseled using the decision aid to patients who are not. We anticipate total experiment running time to be approximately 5 months to recruit and follow up on all patients.

Living donor kidney transplantation (LDKT) is the optimal treatment for end-stage kidney disease (ESKD). But, the evaluation process for a kidney transplant is lengthy, time consuming, and burdensome to the patient. Also, race disparities exist in rates of transplant evaluation completion, transplantation, and LDKT. Our previous and ongoing NIDDK-funded research indicates that cultural factors (i.e., perceived discrimination in health care, religious objection to LDKT), transplant knowledge, and demographic characteristics (e.g., age, education, income) independently and significantly predict time to complete transplant evaluation. In December 2012 the investigators' transplant center implemented a one-day streamlined evaluation process, dubbed Kidney Transplant Fast Track (KTFT), but it has not been evaluated for efficacy or cost effectiveness. Thus, the investigators propose a quasi-experiment to determine the efficacy and cost-effectiveness of the KTFT (n=1030) compared to historical controls (n=1140) who were recruited for the investigators' current NIDDK study to increase transplant rates. At the same time, the investigators will conduct a randomized controlled trial (RCT) targeting vulnerable patients with the educational component of the TALK intervention (Talking About Live Kidney Donation) to increase LDKT. For both components of the proposal, the investigators will target vulnerable populations because they are most at risk for extended evaluation times and lower rates of LDKT. Using CONSORT standards, participants will be randomly assigned to TALK (n=515) versus no-TALK (n=515) conditions and undergo two interviews at pre-transplant work-up and at completion of transplant evaluation in order to: (1) test whether KTFT and TALK will reduce transplant evaluation time, and increase rates of transplant and LDKT in members of vulnerable groups; (2) determine whether engaging in a streamlined and coordinated-care evaluation experience within the transplant center reduces negative perceptions of the healthcare system; and (3) test the cost effectiveness of the KTFT with TALK relative to standard practices. The results of this two-pronged approach will help pave the way for other transplant centers to implement a fast-track system at their sites, improve quality of care by transplanting a larger number of vulnerable patients, and may help address stark race/ethnic disparities in rates of LDKT.

The purpose of this study is to increase understanding about living kidney donation (LKD) among Hispanic/Latino patients and public by increasing knowledge and positive attitudes about LKD. Improving Hispanics' understanding about LKD will ensure that Hispanic patients and public are fully informed of the treatment options for End Stage Kidney Disease.

The objective of this study is to evaluate kidney transplant candidates' comprehension about increased risk donor kidneys necessary for informed consent. We have developed a web-based tool that educates and assesses candidates' comprehension (Inform Me), as a supplement to current informed consent processes. We will then compare the effectiveness of the current informed consent processes supplemented by Inform Me, with the current consent processes alone for kidney transplant.

This study will assess the influence of hepatic impairment on the pharmacokinetics, safety and tolerability of a single dose of MDV3100 in male subjects. The study will consist of two treatment arms. Arm A will assess the influence of mild hepatic impairment, and Arm B will assess the influence of moderate hepatic impairment. Data obtained from subjects with hepatic impairment will be compared to data from Body Mass Index (BMI) and age-matched subjects with normal hepatic function.

The purpose of this study is to describe the circadian rhythm of serum and salivary phosphorus in patients with chronic kidney disease and determine its' modification in response to changes in dietary phosphate load.

The purpose of the study is to learn more about how advanced glycation end-products can affect insulin resistance, inflammation and blood vessel health in people with kidney disease.

This is a Phase 1 single dose study conducted to evaluate the PK and PD of pegloticase administered to hemodialysis patients. A single dose of pegloticase will be administered intravenously to male or female hemodialysis patients (N = 12) starting 3 hour prior to dialysis. The study consists of a Screening Period, a Treatment Period, and Follow up Period.
