Filter by:This is a multi-center, open-labeled, non-comparative study to examine the safety and efficacy of ASP1585 for long-term dosing in chronic kidney disease and hyperphosphatemia patients on hemodialysis.
The purpose of this study is to observe the effectiveness and safety of the use of a low initial dose regime (iPTH/100) in chronic kidney disease patients with secondary hyperparathyroidism (PTH>300pg/mL) and that require dialysis at least 3 times per week.
People with kidney transplants often develop bone disease. One reason for bone disease may be overactivity of a gland in the neck called the parathyroid gland. Overactivity of the parathyroid gland may be caused by lack of Vitamin D in the body. It has recently been discovered that many patients with kidney transplants have low Vitamin D levels. The investigators are examining the effects of doxercalciferol on parathyroid hormone levels, proteinuria and bone turnover markers in people who have had a kidney transplant.
Post market observational survey of a vascular access device for access-challenged patients. Data collection efforts focused on patient medical and access history and implant procedure results.
This study will enroll 25 patients with kidney disease to evaluate the effects of different doses of sodium bicarbonate (baking soda) on levels of bicarbonate in the blood, kidney function and muscle strength. The investigators will also evaluate safety and tolerability of different doses.
This study will investigate how the levels of a single dose of CTAP101 changes in the body over time (pharmacokinetics, PK) and how CTAP101 affects other mineral and hormonal balances (pharmacodynamics, PD) in patients with Stage 3 or 4 chronic kidney disease (CKD) with vitamin D insufficiency and secondary hyperparathyroidism (SHPT).
End-stage renal disease is a global epidemia with an estimated incidence of 7% per year and high morbidity-mortality rate. Early detection of chronic kidney disease (CKD) and intervention for CKD complication is important to retard renal progression. However, "traditional uremic toxin" or "small water-soluble molecules" are poorly correlated with the renal function, uremic symptoms and outcomes of CKD patients. Putative protein-bound solute, p-cresol, is accumulated in ESRD patients receiving dialysis therapy. This uremic solute was associated with endothelial dysfunction, immune dysregulation and can predict outcome in hemodialysis patient. P-cresol inhibits endothelial cell proliferation and endothelial response to inflammatory cytokines. In vitro, p-cresol decreases leukocyte transendotherliar migratory function and inhibit production of phagocyte reactive species. Clinically, p-cresol plays a pathophysiological role in the uremic toxicity. High free serum level of p-cresol is associated with mortality in hemodialysis patients. Information of p-cresol in CKD patients is not available. The investigators hypothesized p-cresol can be accumulated in early CKD and have a positive correlation with the morbidity- mortality of CKD patients. Value of p-cresol in different stages of CRF is still unknown. Information of p-cresol in CKD patients is not available. The investigators hypothesized p-cresol can be accumulated in early CKD and have a positive correlation with the morbidity- mortality of CKD patients. The principal aim of this prospective cohort study is to investigate the association between total serum levels of p-cresol and the glomerular filtration rate. The correlation of level of p-cresol and morbidity-mortality in CKD patients will be also evaluated. To determine the relationship, patients of nephrology clinic with a diagnosis of CKD were enrolled in this prospective study and follow-up for 1-year period. The association between total and free serum levels of p-cresol and the glomerular filtration rate were evaluated in CKD patients. The p-cresol level was correlated with other many inflammatory markers (white blood cell counts, ferritin, hs-crp, leptin) and also with the hospitalization rate secondary to cardiovascular and infectious event. The renal outcome and all-cause mortality was assessed. Determination of this relationship can help to establish an accurate marker for early detection of CKD and also its prognostic role in CKD patients.
This study examines patients with chronic kidney disease-related anemia and measures changes in the metabolism of the heart using FDG/PET scanning, before and 6 months after their health-care provider has initiated anemia management therapy with the FDA-approved drug darbepoetin alfa (Aranesp), which is approved for chronic kidney disease-related anemia. The investigators hypothesize that the heart has abnormal metabolism with the anemia of chronic kidney disease but this improves after correction of this anemia with darbepoetin alfa.
This is a pilot observational study to evaluate subjects with chronic kidney disease acceptance of an alert device linked to an informational website intended to increase recognition of chronic kidney disease, and to guide patients and providers to the safe delivery of care required for this disease. Primary device was a bracelet with the alternative of a key fob with same information supplied when requested. Patients usage of the device was evaluated by survey with Likert scale as to whether the device is 0 = not useful, 1 = somewhat useful, 2 = extremely useful
Overall research aims: This study will examine the effect of vitamin D supplementation on the function of the endothelium and microcirculation of patients with chronic kidney disease and vitamin D deficiency. Hypothesis: Vitamin D therapy in patients with CKD and concomitant vitamin D deficiency will improve endothelial, and therefore microcirculatory function, reduce levels of oxidative stress and thus reduce the risk of future CVS events in this population.
