Filter by:A single blind, six week dietary intervention will be conducted in order to evaluate the impact of fiber fortified foods on blood urea nitrogen, kidney function and quality of life in patients presenting with a moderate to severe decline in kidney function.
The purpose of this study is to examine the effect of 6 months of daily beta-hydroxy beta-methylbutyrate (HMB) supplementation on the physical function and the health of bones, arteries and heart in hemodialysis patients.
This study is to research two questions. First, is vitamin D3 more effective than vitamin D2 in raising 25-hydroxyvitamin D [25(OH)D] levels in chronic kidney disease (CKD) patients? And secondly, what are the differential effects of vitamin D2 and vitamin D3 on other mineral metabolism parameters?
People with hypertension are at a higher risk for cardiovascular disease and death so it is important to lower blood pressure to normal levels as quickly as possible. Previous research has established that renal nerve denervation successfully lowers blood pressure measured in the arm in the physician's office. This study is being conducted so that the investigators can determine whether renal nerve denervation also helps to lower blood pressure over 24 hours, as well as central aortic blood pressure, which is pressure exerted by the aorta closer to the heart and may be a better predictor of cardiovascular problems. The investigators also want to know whether these beneficial effects on blood pressure can last up to 2 years, whether renal denervation reduces the number of medications patients need to take, and whether it reduces glucose and insulin levels in the blood since hypertension is also related to obesity and diabetes.
Forced blockade of the renin-angiotensin-system (RAS) by using direct renin inhibition (DRI) has long been propagated to effectuate beneficial outcomes. However, recent large clinical trials have outlined harmful effects for DRI in combination with other forms of RAS blockade. To date, information regarding DRI as RAS-blocking monotherapy is very limited. Furthermore, it remains to be elucidated how DRI and angiotensin receptor blockers affect the so-called 'classical' and 'alternative' RAS molecularly. As components of the 'alternative' RAS (e.g. Ang 1-7) have moved into research focus, it would be of importance to determine angiotensin regulation with medical RAS blockade. In this prospective, single-center randomized trial over 10 weeks, 24 patients with chronic kidney disease (CKD) stage III-IV (eGFR 15-59 ml/min) will be randomized to take either aliskiren (up to 300 mg per day) or candesartan (up to 16 mg per day) after a two week run-in phase where all RAS-blockers are eliminated. The investigators will then employ a novel mass spectrometry-based quantification method (after run-in and 10 weeks) to capture the concentrations of ten different angiotensin peptides (including angiotensin I and II, angiotensin 1-7 and angiotensin 1-5). The investigators hypothesize that significant differences exist between angiotensin levels in CKD patients with DRI compared to angiotensin receptor blockers. Specifically, the investigators expect to determine the regulation of the alternative RAS represented by angiotensin 1-7 with proximal versus distal blockade of the system. Our data might contribute to a more profound understanding of results from registries and clinical trials beyond the clinical effects of RAS blockade. Further, the study's results might help to individualize and optimize RAS-blocking therapy strategies in CKD patients.
Use of Paricalcitol in stage Vd Chronic Kidney Disease patients, over the effect of inflammatory and oxidative stress parameters.
Objective: To show that the frequency of aldosterone breakthrough is lower when RAS blockers are given at bedtime compared to on awaking, and to analyze the determinants and consequences of aldosterone breakthrough. Duration of the study: Inclusion 2 years, follow-up one year, total 3 years Design: prospective, multicenter, randomized, controlled, open label, two parallel groups. Main selection criteria: Inclusion criteria - Chronic kidney disease stage 3 to 4, - ACEI (captopril, enalapril, or ramipril), and/or ARB (losartan, valsartan, or irbesartan) on awaking for at least three months, - History of hypertension or proteinuria > 0,5 g/24h or g/g créatininurie. Exclusion criteria - Office blood pressure ≥ 160/100 mmHg, - Anti-aldosterone (spironolactone, eplerenone) or potassium sparing diuretics (modamide, amiloride), or direct renin inhibitor. Evaluation criteria: Primary: Serum aldosterone levels at one year. Secondary: - Serum aldosterone/renin ratio, - 24h urine aldosterone, - Significant aldosterone breakthrough defined by a >10% increase of serum aldosterone levels over baseline values, - Aldosterone breakthrough defined by an increase of serum aldosterone levels over baseline values, - HbA1c, - Urinary albumin/creatinine ratio (UACR) on spot morning urine samples, - Systolic home blood pressure (SBP), - Estimated glomerular filtration rate (eGFR) using the MDRD equation.
The purpose of this study is (1) to determine whether a 12-month trial of patients from underserved communities with clinically significant gum disease and kidney disease randomly assigned to intensive gum disease treatment or delayed treatment is feasible and (2) to determine the variability of various tests of kidney function and inflammation in response to intensive gum disease treatment.
The study's purpose is to address the challenges of providing stage-appropriate chronic kidney disease (CKD) education and care by developing innovative programs using a CKD Patient Navigator system and an EHR (electronic health record)-based enhanced electronic communication system specific for a CKD patient and her/his physicians/caregivers. The investigators plan a randomized controlled trial of these innovations to examine the utility and effectiveness of these special interventions. The investigators' CKD registry aids in identifying patients for recruitment for the randomized control trial. Patients are randomized into one of four groups. The four groups are: 1) the control group using MyChart; 2) an enhanced personal health record (PHR) included in MyChart consisting of 35 websites chosen to disseminate CKD stage-specific goals of care and CKD education; 3) the patient navigator, a lay professional trained in the specifics of chronic kidney disease navigation with a focus on the needs of their patients based on the National Kidney Foundation Disease Outcomes Quality Initiative; 4) the patient navigator combined with the enhanced MyChart. The investigators hypothesize that a CKD Patient Navigator program will develop a more prepared, proactive patient-caregiver team than usual care; the enhanced PHR will produce a more informed, engaged patient than usual care; the CKD Patient Navigator arm and enhanced PHR will demonstrate a slower rate of decline in eGFR (glomerular filtration rate) than usual care. The results of this study will lay the foundation for a larger multi-center national clinical trial that will build upon the feasibility and knowledge gained from this planning grant.
The main purpose of this research program is to reduce the burden of end-stage organ disease on individuals, families, healthcare systems, and society by increasing the availability of donor organs for transplantation. Consistent with this aim, the project further examines strategies to increase access to and reduce disparities - racial, economic, gender - in live donor kidney transplantation (LDKT). Specifically, we expand the research and intensity of an innovative House Calls intervention developed by the principal investigator by including other minorities and socioeconomically disadvantaged patients and by adding a novel Patient-Centered Decision Support component. The main study hypothesis is that participants receiving the novel intervention (House Calls + Patient-Centered Decision Support) will have a higher proportion of LDKT's by the 2-year study endpoint.
