Active clinical trials for "Kidney Diseases"

The development of diabetic nephropathy has been linked to several genetic polymorphisms, including those related with homocysteine metabolism such as the methylenetetrahydrofolate reductase (MTHFR)and the cystathionine-beta-synthase genes. Such alterations are associated with hyperhomocysteinemia, which is a known independent risk factor for the development of endothelial dysfunction and cardiovascular disease. In the Mexican population there is a high prevalence of the C677T MTHFR mutation. The investigators performed this study to evaluate the prevalence of this polymorphism in type 2 diabetic patients with diabetic nephropathy compared with type 2 diabetic patients without nephropathy, besides evaluating the relationship of hyperhomocysteinemia with endothelial dysfunction and microalbuminuria before and after the administration of folic acid. We proposed that the endothelial dysfunction caused by the hyperhomocysteinemia could be reversed after the administration of folic acid.

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.

To test the hypothesis that total parathyroidectomy retards cardiovascular calcification, improves bone mineral density, reduces cardiac hypertrophy and arterial stiffening in end-stage renal disease patients on maintenance dialysis.

This study is being conducted to evaluate sitaxsentan dosing in subjects with chronic kidney disease.

This trial is designed to determine if the use of a computer algorithm designed to optimize mineral outcomes in dialysis patients increases the number of patients achieving the desired target endpoints for calcium, phosphorus and parathyroid hormone.

The Polyflux HD-C4 (Gambro Renal Products) is a new dialyzer based on the existing Polyflux H membrane and dialyzer technology, but which achieves a performance comparable to Polyflux 210H in a significantly smaller device. The objectives of this study are: To compare and contrast small and large molecule removal by the Polyflux HD-C4 and Polyflux 210H dialyzers under conditions of routine hemodialysis; and, To compare and contrast the ease of use of the Polyflux HD-C4 dialyzer with that of the Polyflux 210H under conditions of routine clinical use for hemodialysis.

Hypothesis: Free light chain removal haemodialysis will increase the rate of renal recovery in patients with cast nephropathy, severe renal failure and de novo multiple myeloma. This study will randomise patients with multiple myeloma and severe renal failure to treatment to remove free light chains by haemodialysis or not.

The goal of this proposal is to investigate the potential for ACE-inhibitors (ACE-I)(drugs primarily used to treat hypertension or congestive heart failure) to prevent or delay cardiovascular disease (CVD) in older adults with chronic kidney disease (CKD) by examining their impact on aortic stiffness in people with stage 3 CKD in a randomized, controlled study.

The purpose of this study is to ascertain whether Arotinolol Hydrochloride reduces mortality and cardiovascular events in chronic kidney disease stage 5 patients with hypertension.

Controlling secondary hyperparathyroidism (sHPT) in maintenance hemodialysis (MHD) patients is cumbersome, partly due to patient's non-adherence to prescribed drugs. The main objective of this study was to assess whether an integrated care (IC) approach, in which adherence data are integrated in the decisional process, led to improved therapeutic control of secondary hyperparathyroidsm and higher percentages of bone metabolism targets as compared to a usual care (UC) approach, in which biological values represent the main stem of the decisional process. The predefined hypothesis was that patients of the IC group should reach the iPTH targets using 25% less doses of cinacalcet at 6 months than those of the UC group.
