Active clinical trials for "Kidney Failure, Chronic"

Vitamin D is a prohormone obtained through diet, supplementation, or sun exposure. Once absorbed, this nutritional vitamin D undergoes a two-step reaction in the liver and in the kidney to become the active hormone, calcitriol. Besides the kidney, many other body tissues are capable of local vitamin D activation. This local tissue activity is important for maintenance of health and relies on adequate levels of nutritional vitamin D. Not only are dialysis patients deficient in calcitriol due to kidney failure, but they are also deficiency in nutritional vitamin D. Low levels of vitamin D have been associated with higher rates of death, heart and blood vessel disease, osteoporosis, falls, cancer, and autoimmune diseases. Despite this, there is a lack of randomized controlled trials (RCT) examining the effects of nutritional vitamin D in hemodialysis (HD) patients. The investigators hypothesize that long-term supplementation with nutritional vitamin D in HD patients improves survival and cardiovascular outcomes. Before embarking on a large scale RCT, the investigators propose a small pilot RCT with 20 hemodialysis patients to: i) To determine the effects of cholecalciferol (vitamin D3) in raising blood vitamin D levels; ii) To determine the feasibility and barriers to successful randomization and adherence to treatment protocols, which will inform subsequent studies.

MYRE is a phase III multicentric controlled national clinical trial conducted in patients with multiple myeloma and renal failure related to myeloma cast nephropathy (MCN). Its aims are to assess (1) the efficacy of bortezomib plus dexamethasone (BD), compared with cyclophosphamide, plus bortezomib and dexamethasone (C-BD) in patients with inaugural MCN not requiring hemodialysis; and (2) in patients with inaugural severe renal failure secondary to biopsy-proven MCN and requiring hemodialysis that of an intensive hemodialysis regimen using either a dialyser with very high permeability to proteins (TheraliteTM) or a conventional high-flux dialyser, while receiving chemotherapy with BD.

A double-blind, randomized trial aimed to compare the efficacy of two formulations of erythropoietin in patients with chronic renal failure on hemodialysis

Primary Objective: To demonstrate that use of glucose sparing prescriptions, Dianeal, Extraneal, Nutrineal (D-E-N) versus Dianeal only, in diabetic (Type 1 and Type 2) Continuous Ambulatory Peritoneal Dialysis (CAPD) patients leads to improved metabolic control as measured by the magnitude of change from the baseline value in the HbA1c levels. Secondary Objectives: To demonstrate that use of glucose-sparing Peritoneal Dialysis solutions (D-E-N versus Dianeal only) in diabetic (Type 1 and Type 2) CAPD patients leads to lower glycemic-control medication requirements, decreased incidence of severe hypoglycemic events requiring medical intervention, improved metabolic control, nutritional status, and Quality of Life.

This is a two-staged study of a single dose of 200 mg of bosutinib given to subjects with renal impairment and matching healthy volunteers. In Stage 1, only subjects with severe renal impairment and subjects with normal renal function will be enrolled. Subjects with mild and moderate renal impairment will be enrolled in Stage 2 if the results from Stage 1 suggest a substantial difference in PK profiles between subjects with severe renal impairment and subjects with normal renal function.

Hypothesis: Patients starting peritoneal dialysis with a glucose-based regimen have high sympathetic activity in response to an increase in leptin and insulin. Converting patients from a regimen of only glucose containing dialysate to a regimen with non-glucose-based solution, icodextrin, will reduce the insulin and leptin levels and will reverse dialysis-induced increases in sympathetic activity.

A pilot randomized trial that compares a new renal nutritional supplement with the standard renal vitamin. The primary objective is to compare two doses (medium and high) of the new supplement with the renal vitamin currently being prescribed to people with End Stage Renal Disease (ESRD). Secondary objective is to demonstrate the feasibility of recruitment for a definitive larger trial.

The purpose of this study is to test whether a dialyzer with a higher than usual permeability for proteins can eliminate proinflammatory proteins from the blood of patients on regular maintenance hemodialysis who have chronically elevated levels of inflammation markers such as C-reactive protein (CRP) in their blood.

Hyperparathyroidism (HPT) is common in people with a kidney transplant. Patients with HPT often have high parathyroid hormone (PTH) levels and may have large parathyroid glands in the neck. Patients with HPT can develop bone disease (osteodystrophy). This bone disease can cause bone pain, fractures, and poor formation of red blood cells. Other problems from HPT may include increases in blood levels of calcium (hypercalcemia) and low blood levels of phosphorus (hypophosphatemia). The high calcium levels may cause calcium to deposit in body tissues. Calcium deposits can cause arthritis (joint pain and swelling), muscle inflammation, itching, gangrene (death of soft tissue), heart and lung problems or kidney transplant dysfunction (worsening of kidney transplant function). The purpose of this study is to evaluate the effects of cinacalcet (Sensipar/Mimpara) on high calcium levels in the blood in patients with HPT after a kidney transplant.

OBJECTIVES: I. Assess the clinical safety and long term effects of recombinant human growth hormone on a defined range of nutritional indices in malnourished chronic hemodialysis and continuous ambulatory peritoneal dialysis patients.
