Filter by:The proposed research aims to examine whether regular aerobic exercise can preserve renal function, improve aerobic capacity, physical and psychosocial function, strength, cardiovascular function, general well-being and quality of life. Ultimately, the research aims to prove that exercise is a more cost-effective and a more efficient use or healthcare resources used in the treatment of patients with CKD. Exercise is a relatively cheap treatment option which is readily available and accessible for this patient population. establish if, compared with usual care, an exercise programme for pre-dialysis CKD patients; 1. Preserves renal function. 2. Improves aerobic capacity, physical and psychosocial function, strength, cardiovascular function, general well-being and quality of life.
The main purpose of this study is to see whether PT20 can help people with a high level of phosphate in their blood (called Hyperphosphatemia) that are being treated with dialysis for kidney disease.
The purpose of this study is to look at the tolerability and safety of LY3113593. Study doctors will see how safe it is and whether it produces side effects following a single injection into a vein or under the skin in healthy participants (Part A) and participants with chronic kidney disease treated with hemodialysis (Part B). The study will also measure how much of the study drug gets into the blood stream, how long it takes the body to get rid of the study drug and what effects the study drug has on the body. This is the first time that this study drug is being given to participants. This study is for research purposes only and is not intended to treat any medical condition. For each participant, the study will last about 85 days, not including screening. Screening is required within 28 days prior to the start of the study.
To date, most observational and all intervention studies have defined hypertension on the basis of clinic blood pressure (BP). Measurement of BP outside the clinic with home or ambulatory BP provides a better estimate of the risk of cardiovascular disease and all-cause mortality. Using clinic and ambulatory BPs, patients can be categorized as normotensive (normal clinic and ambulatory BPs), white-coat hypertension (elevated clinic BP with normal ambulatory BP), masked hypertension (normal clinic BP with elevated ambulatory BP), and sustained hypertension (elevated clinic and ambulatory BP). Approximately one third of patients with chronic kidney disease (CKD) with normal clinic BP have elevated ambulatory BP (masked hypertension). We demonstrated that, among participants from the Chronic Renal Insufficiency Cohort (CRIC) study, low estimated glomerular filtration rate (eGFR) and elevated proteinuria are associated with increased odds of masked hypertension. Additionally, participants with masked hypertension had increased risk for target organ damage as assessed by left ventricular mass and pulse wave velocity. These results in participants with CKD are consistent with prior studies in patients with normal renal function that demonstrated a two-fold increased risk for cardiovascular events in patients with masked hypertension compared to patients with normal clinic and ambulatory BP. Despite this elevated risk for adverse outcomes, patients with masked hypertension have been excluded from hypertension trials because of their normal clinic BP. Therefore, it is unknown whether the reduction in target organ damage and adverse cardiovascular outcomes associated with treatment of hypertension extends to patients with masked hypertension. To address this important gap in knowledge, we are planning a randomized, controlled trial to evaluate whether antihypertensive treatment can modify BP patterns in patients with masked hypertension, that is, convert them to controlled clinic and ambulatory BP. We will also evaluate the effect antihypertensive treatment on target organ damage in patients with masked hypertension. The current study is a pilot randomized controlled trial to evaluate the feasibility of the planned trial and the effect of antihypertensive therapy on clinic and ambulatory BP, proteinuria, and target organ damage in patients with masked hypertension.
Chronic kidney disease is associated with the accumulation of various metabolites, i.e., uremic retention solutes. Evidence is mounting that the colonic microbiota contributes substantially to these uremic retention solutes. Indoxyl sulfate and p-cresyl sulfate are among the most extensively studied gut microbial metabolites, and are associated with cardiovascular disease, overall mortality and chronic kidney disease progression. The most important regulator of colonic bacterial metabolism is nutrient availability and especially the ratio of available fermentable carbohydrate to nitrogen, which can be modified by intake of so-called prebiotics (non-digestible food ingredients). Arabinoxylan oligosaccharides (AXOS) are a recently developed group of prebiotics, and already demonstrated a decreasing effect on intestinal generation of p-cresol in healthy individuals. Whether prebiotics in general, and AXOS more specifically, can influence intestinal generation of microbial metabolites in predialysis patients has not been studied to date. An interventional study with AXOS will therefore be initiated to test the hypothesis that AXOS can decrease intestinal generation and serum concentrations of microbial metabolites in patients with CKD not yet on dialysis.
This is an observational clinical research on patients with chronic kidney disease who are not on hemodialysis and receiving darbepoetin alfa to treat diagnosed renal anemia; the major objective is to explore novel erythropoiesis stimulating agent (ESA) response index in association with deterioration of renal function as well as occurrence of cardiovascular disease events.
The purpose of this study is to evaluate the effects and efficacy of dietary sodium restriction by mean of a new healthcare approach in patients with chronic kidney disease. The test persons in the intervention group are actively supported to adhere to a restricted sodium diet with a structured self-regulation program to implement sodium recommendations that are in current guidelines.
The objective of the study is to evaluate the efficacy and safety of KRX-0502, administered without food, in treating iron deficiency anemia in subjects with stage 3 to 5 non-dialysis dependent chronic kidney disease (NDD-CKD).
Children with chronic kidney disease, even after transplantation, may be at risk for bone problems due to an imbalance of calcium and phosphorus in the blood, especially as their kidneys progressively fail to function. While some drug and diet treatments are available to prevent such bone disease, many children refuse to take them due to bad taste and tummy cramps. If calcium and phosphorus status remain abnormal for a long time, hard crystals can form in the blood vessels, eventually clogging them and resulting in heart problems. Investigators are studying possible new methods to help the kidneys maintain a normal balance of nutrients in the blood which is important for growing healthy bones and the prevention of side effects in blood vessels that can lead to heart disease. One method is to improve the team work of a hormone FGF-23 and a protein called Klotho that together stimulate the kidneys to increase phosphate removal. Investigators propose that this problem may be due to low blood zinc levels which often occur in children with kidney disease. Thus, in this study, investigators propose to first measure zinc in blood from children with chronic kidney disease (CKD) or who have had kidney transplants to assess zinc and phosphate status, the hormone FGF-23 and its assistant Klotho. If zinc status is low, the children will receive zinc supplementation for 3 months. After treatment with zinc, the same blood measurements will be repeated to determine if the zinc supplements have helped the hormones to remove phosphate from the body. If this pilot project is successful, investigators will then consider a larger scale project involving adult patients as well as pediatric patients from other pediatric centers. This project will also guide investigators as to whether they need to introduce zinc measurements as part of routine testing of CKD and transplant patients. In addition to measuring zinc levels in study participants, trace elements (TE) will also be measured. These include heavy metals such as cadmium, chromium, nickel, vanadium, copper, lead, manganese and selenium. Very little is known about levels and metabolism of TE in CKD especially before dialysis. In adults, cadmium, chromium, nickel, and vanadium probably accumulate in hemodialysis patients, while copper and lead may accumulate. Manganese, selenium are probably deficient. The study will allow investigators to obtain the information about TE in this group of pediatric patients.
The primary objective of this clinical study is to evaluate the preliminary safety and effectiveness of using the FLEX-1 device for the creation of an arteriovenous fistula (AVF) in patients requiring chronic hemodialysis.
