Filter by:The aim of this study is to compare the preventive effect of Telmisartan(Micardis) versus placebo control on the transition to overt nephropathy in patients with diabetic nephropathy manifesting microalbuminuria associated with type II diabetes, and to evaluate the efficacy and safety of Telmisart (Micardis, Gliosartan, Kinzal, Kinzalmono, Predxal, Pritor, Samertan, Telmisartan) for diabetic nephropathy patients.
The general aim of this study is to compare telmisartan 80 mg with valsartan 160 mg in hypertensive patients with type 2 diabetes and overt nephropathy with adjusted blood pressure beyond the target of 130/80 mmHg after one year of treatment. The primary objective of this study is to show that telmisartan 80 mg is at least as effective (i.e., not inferior) and possibly superior to valsartan 160 mg in reducing 24 hour proteinuria after one year of treatment.
The purpose of the study is to evaluate the effectiveness and safety of olmesartan versus placebo on the progression of diabetic renal disease.
1. To determine and compare the efficacy of Tacrolimus/Rapa versus Tacrolimus/MMF-based immunosuppression (in conjunction with initial short-term steroids and polyclonal antibody administration) in Type 1-diabetic patients undergoing simultaneous pancreas/kidney allograft transplantation. 2. To evaluate the safety of Tacrolimus/Rapa versus Tacrolimus/MMF in terms of drug-related complications and overimmunosuppression-associated complications, particularly under monitoring of the pharmacokinetic profile of all drugs administered.
Experimental data suggest that oxidative stress and endothelial dysfunction are key players in the pathogenesis of diabetic nephropathy. In the last few years the investigators were able to establish a method to assess endothelial function of the renal vasculature in humans and started to systematically study a variety of cardiovascular disorders known to be associated with endothelial dysfunction in other vascular beds, including hypertension, hypercholesterolemia and type-2 diabetes. In patients with type-2 diabetes the investigators could demonstrate that despite unaltered basal and stimulated NO-activity, the renal response to the antioxidant vitamin C was more pronounced compared to control subjects. These data suggest that oxidative stress is increased in the renal vasculature of diabetic patients. Furthermore, NO-activity in diabetic patients appears to be upregulated to compensate for the increase in oxidative stress. This hypothesis is supported by the demonstration of increased endothelial nitric oxide synthase (eNOS) expression in kidney biopsies of diabetic patients. The major focus of the investigators' current research activities is to assess the role of endothelial dysfunction in the very early stages of diabetic nephropathy. To this end, patients with increased fasting glucose or metabolic syndrome will be studied in comparison with an age-matched control group. Endothelial function and the role of oxidative stress will be assessed in the renal vasculature in all groups. In parallel, the investigators will study endothelial function in the forearm by venous occlusion plethysmography and in the retinal vasculature by scanning laser doppler flowmetry to dissect regional differences in the regulation of endothelial function. Further aspects include the role of microalbuminuria, glomerular hyperfiltration, and endogenous inhibitors of NO synthase such as NG,NG-Dimethyl-L-Arginine (ADMA). In a therapeutic approach, the investigators will determine the effects of various antioxidant treatment strategies on endothelial function and their potential role in the prevention of diabetic nephropathy.
The purpose of this study is to determine whether sulodexide is effective in slowing or preventing the progression of diabetic kidney disease.
The purpose of the study is to determine whether treatment with sulodexide is effective in reducing the level of urine albumin excretion in patients with early diabetic kidney disease expressed as microalbuminuria.
The purpose of this study is to determine whether avosentan (SPP301) is effective in decreasing morbidity and mortality in patients with diabetic nephropathy.
The primary aim is to evaluate the anti proteinuric effect of increasing doses of the ACE inhibitor, lisinopril: 20, 40 and 60 mg daily in type 1 diabetic patients with hypertension and diabetic nephropathy. The secondary aim is to evaluate the effect on blood pressure (24 hour ambulatory blood pressure) and kidney function (glomerular filtration rate (GFR)). The tertiary aim is to evaluate differences in response to treatment according to ACE/insertion/deletion (ID)-genotypes and other genetic variants in the genes of the renin angiotensin system.
The primary purpose of this study is to test the effectiveness and tolerability of Niaspan® to improve the levels of blood fats ("good" and "bad" cholesterol and triglyceride levels) in people who have kidney damage due to diabetes. A secondary goal is to test whether Niaspan® slows down further development of kidney damage.
