Filter by:Low molecular weight heparin (LMWH) is injected in the dialysis circuit at the start of the session. In the present study we compare 3 different methods of injection of LMWH: parameters of dialysis efficiency and clotting are measured. The study lasts 3 sessions for each patient.
This study is designed to describe the physiological response to increased and decreased dietary phosphate intake on various parameters of mineral metabolism in the blood and urine of individuals with Chronic Kidney Disease stage 3 and 4 with normal serum phosphate levels. This detailed study will give us a far greater understanding of the role of diet in abnormal mineral homeostasis early in the progression of this chronic disease. The findings of this study will help both physicians and dietitians better determine the optimal time to introduce dietary therapy in CKD.
Patients with chronic kidney disease (CKD) have a higher mortality rate than the general population, with cardiovascular disease (CVD) accounting for approximately 50% of deaths. Vascular calcification is a common finding in patients with CKD. Furthermore, patients with CKD develop secondary hyperparathyroidism, partly because of a decrease of calcitriol synthesis on the kidney. Treatment of secondary hyperparathyroidism includes use of activated vitamin D including calcitriol and paricalcitol. Recent evidence in dialysis patients suggest an improved survival in patients using paricalcitol compared to calcitriol. Studies in uremic rats suggests that there are differential effects of calcitriol and paricalcitol in expression of markers of soft-tissue calcification independent of calcium-phosphorus product. Calcitriol increased calcification of vascular smooth muscle cells cultured in calcification media. There was also significant increase in pulse pressure in animals treated with calcitriol. The investigators hypothesize that these different forms of vitamin D may have differential effects in vascular calcification progression in CKD patients.
The primary objective of this study is to assess the safety, tolerability and activity of escalating multiple doses of SBR759 in patients with chronic kidney disease on hemodialysis.
Patients with chronic kidney disease (CKD) are commonly deficient in vitamin D, with low levels of both calcidiol (25 hydroxy vitamin D) and calcitriol (1,25-hydroxy vitamin D). Patients with CKD are also known to have abnormalities in their immune cells, increased susceptibility to infection and increased prevalence of malignancies. In patients without kidney disease, repletion of vitamin D appears to help some immune mediated diseases. Thus it is logical that patients with CKD who are vitamin D deficient may benefit from repletion of vitamin D, in either its native form (cholecalciferol/ergocalciferol) or in the form of calcitriol or its analogues. However, no interventional data demonstrates that repletion positively impacts immune status in CKD patients. To test this hypothesis, a large interventional study will be required. However, prior to conducting this study, several important steps are needed. The present proposal aims to generate the necessary data to appropriately plan and conduct a future multi center interventional study. Specifically, we will examine the following specific aims in a population of CKD stage 3 and 4 subjects from Indiana University Affiliated Nephrology Clinics and determine 1. if abnormalities in immune cells and immune blood tests are related to abnormalities in vitamin D. 2. how reproducible these changes are on repeat testing and 3. if repletion of vitamin D changes these cells and immune blood tests in a small pilot study.
To test the hypothesis that PPAR-gamma agonist, rosiglitazone, induces carotid plaque regression in diabetic ESRD patients on maintenance PD via its anti-inflammatory property.
This study will investigate the levels of CTA018 in the body over time (pharmacokinetics, PK) in patients with chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPT), undergoing regular hemodialysis. This study will also investigate the safety and effects of different strengths of CTA018, on parathyroid hormone (PTH) levels.
The HYGIA study was designed to investigate prospectively 1. the prognostic value of ambulatory blood pressure (BP) monitoring among subjects primarily evaluated at primary care settings 2. the impact of changes in ambulatory BP during follow-up in cardiovascular, cerebrovascular, metabolic, and renal risk in hypertensive patients 3. the influence of circadian time of treatment in cardiovascular, cerebrovascular, metabolic, and renal risk in hypertensive patients 4. the prevalence of an altered BP profile as a function of antihypertensive treatment, circadian time of treatment, age, and presence of diabetes, among other factors.
This single arm study will assess the efficacy and safety of monthly administration of subcutaneous Mircera for the maintenance of hemoglobin levels in patients with chronic kidney disease on peritoneal dialysis. Patients currently receiving maintenance treatment with subcutaneous ESA will receive monthly subcutaneous injections of Mircera, with the starting dose derived from the last weekly ESA they had been receiving. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
A current trend in dialysis membrane engineering is to maximize the permeability for larger low-molecular weight proteins while retaining albumin. Protein-leaking dialysis membranes do not meet these requirements. Particularly in convective procedures, such as hemodiafiltration, their albumin leakage is too high [10]. POLYNEPHRON™, the membrane which is built in to the new Nipro ELISIO® dialyzer, is a new dialysis membrane, produced by applying an innovative spinning technique. The incentive of its development was to improve the characteristics of existing dialysis membranes, i.e., realizing a steeper sieving profile for low-molecular weight proteins without significant loss of essential larger proteins at best biocompatibility properties, for a more adequate dialysis therapy. Purpose of the planned study is to demonstrate the superior performance at lower albumin loss in different dialysis procedures of the new Nipro ELISIO® dialyzer compared with a control dialyzer with regard to the removal of the whole range of uremic toxins.
