Filter by:The proposed study is a pilot study and a first step towards developing an optimized HPV vaccination strategy for girls who have CKD, or are on dialysis or have a kidney transplant.
Phosphorus is a substance in the blood that comes from food and is normally cleared from the body by the kidneys. In patients with kidney disease, excess phosphorus may build up in the body as you eat. This leads to problems with bones and blood vessels over time. In this study, we will compare the blood and urine before and after eating one week of a diet with a protein from plants (soy and grains) and before and after another one week of diet with protein from animals (meat and dairy products). The amount of phosphorus that the kidney puts out in the urine, and the changes in blood hormones in response to the diet will be measured at the beginning and end of each week on the two diets.
The primary objective of the study is to evaluate the safety, tolerability, and pharmacodynamic effects of different oral doses of roxadustat administered 2 times a week (BIW) or 3 times a week (TIW) for up to 4 weeks to participants with chronic kidney disease (CKD) not requiring dialysis.
Tryptophan metabolism in kidney disease will be investigated in patients with chronic kidney disease stages (ADOQI 3-5). Tryptophan levels and respective catabolites will be assessed under hemodialysis.
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.
