Filter by:In recent years, diabetic nephropathy, which may lead to dialysis treatment, is the most prevalent underlying disease of people in developed countries. A wide range of studies have been carried out, from various points of view, to understand the progress of renal dysfunction in diabetic nephropathy. The endogenous nitric oxide synthase (NOS) inhibitor asymmetric dimethylarginine (ADMA) is elevated in patients with chronic kidney disease (CKD) and may have a role in the cardiovascular mortality and morbidity of these patients. In diabetic nephropathy, high ADMA levels were related to progression of diabetic nephropathy. The Fas (CD95) antigen is a cell surface polypeptide belonging to the tumor necrosis factor receptor (TNF-R) family (type I membrane protein) that transduces a death signal after interaction with its ligand. Apoptotic cells are then recognized and removed by phagocytes. Recent studies suggest that, in uremic patients, peripheral blood mononuclear cells undergo accelerated apoptosis and this correlates with Fas levels. There is no data about the effects of Renin angiotensin system blockage (RAS) on CD95 and ADMA levels in diabetic patients with proteinuria. The aim of this study was to find out whether the beneficial effects of RAS blockage in diabetic proteinuria has any relation with the alteration of ADMA and CD95levels. The investigators searched for the effects of ACE inhibitor ramipril on the clinical and laboratory parameters of diabetic patients with proteinuria.
The primary purpose is to assess the role of sympathetic activation for the development and progression of chronic renal failure. Using microneurography sympathetic activity will be registered in various stages of kidney affection or failure and hypertension. A sympatholytic agent will be compared with a non-sympatholytic drug to asses the effect sympathetic activation and on the progression of kidney disease. The effects of a sympatholytic agent on cardiovascular reactivity to various stressors wil be examined.
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.
A prospective, non-randomized two stage monocentric phase II clinical trial to evaluate a de-novo calcineurin-inhibitor (CNI)-free immunosuppressive regimen based on induction therapy with anti-CD25 monoclonal anti-body (basiliximab), mycophenolic acid (MPA), and mammalian target of rapamycin (mTOR) - inhibition with everolimus to determine its safety and to investigate the preliminary efficacy in patients with impaired renal function at the time-point of liver transplantation (OLT) with regards to the incidence of steroid resistant acute rejection within the first 30 days after liver transplantation.
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.
