Filter by:Based upon the preclinical evidence in models of diabetic nephropathy under conditions approximating both type I and II diabetes, treatment with alagebrium appears to have favorable and advantageous effects on the biochemical, structural, pathological and functional hallmarks of diabetic nephropathy. The renoprotective effects of alagebrium in preclinical models favor the evaluation of this drug in patients with type I diabetes.
Diabetic nephropathy has become the single most frequent cause of end-stage renal disease. On a molecular level, at least five major pathways have been implicated in glucose-mediated vascular and renal damage and all of these could reflect a single hyperglycaemia-induced process of overproduction of reactive oxygen species. Recent studies have shown that inflammation, and more specifically pro-inflammatory cytokines play a determinant role in the development of micro- vascular diabetic complications, most of the attention has been focused on the implications of TNF-α in the setting of diabetic nephropathy. Glutathione is the most abundant low-molecular-weight thiol, and Glutathione/ glutathione disulfide is the major redox couple in animal cells. N-acetylcysteine is effective precursors of cysteine for tissue Glutathione synthesis. Not only does N-acetylcysteine exhibit antioxidant properties, but it may also counteract the glycation cascade through the inhibition of oxidation. N-acetylcysteine can also reduce the apoptosis elicited by reactive oxygen species . Indeed, N-acetylcysteine has been shown to inhibit reactive oxygen species induced mesangial apoptosis and to be able to protect cells from glucose-induced inhibition of proliferation.
This study will assess the effects of vitamin D3 supplementation (cholecalciferol; 2000 IU daily) on serum calcium levels, circulating vitamin D levels, and markers of kidney disease and cardiovascular risk among people with diabetes mellitus and early kidney disease. Eligibility criteria include type 2 diabetes and stage 1-2 chronic kidney disease, defined by a urine albumin-creatinine ratio 30-300 mg/g and an estimated glomerular filtration rate ≥ 60 mL/min. Participants will be randomly assigned to treatment with vitamin D3 or placebo, each taken by mouth once daily for a study duration of one year. Study medications will be added to standard treatment, including an angiotensin converting enzyme inhibitor and/or angiotensin II receptor blocker. We hypothesize that vitamin D3, compared with placebo: (1) is well-tolerated and safe among people with diabetes and kidney disease; (2) results in adequate attained circulating vitamin D levels; and (3) positively affects markers of kidney disease and cardiovascular risk.
A dose-ranging study evaluating safety, metabolism and therapeutic dosing of three multiple dose levels of GLY-230 in healthy and diabetic subjects
The NID-2 study, a multicentric study (21 centres enrolled), was planned in two phases: Phase 1(observational study, completed in September 2005): after the identification of a type-2 diabetic population with typical Diabetic Nephropathy (DN), to study of the rate of renal and cardiovascular events during a middle term follow-up. Phase 2(interventional study, started in October 2005): after randomization in two groups, a group (intervention group) is treated with an intensive multifactorial intervention whose aim is to reduce morbidity and mortality due to diabetic complications. The other group (control group) continues the conventional therapy . To avoid bias in the treatment in each center, the randomization was performed for centre.
The purpose of this study is to compare the efficacy and safety of Tripterygium (TW) versus Valsartan (ARB) in the Diabetic Nephropathy (DN).
Introduction: Aldosterone seems to have deleterious effects on the kidneys. Many animal studies and few clinical trials now have shown that suppression of aldosterone by aldosterone receptor blockers ameliorated these effects. Method: In a double-blind, cross over study, 24 patients with diabetic nephropathy who were already receiving either ACE inhibitor(lisinopril 20-40 mg/day ) or ARB( losartan 25-100 mg/day )were given spironolactone( 25 mg during the first month and 50 mg during the second and third month if serum K remained ok) or matching placebo with 1 month of washout in between. All patients were from a single center and exclusively male veterans. Blood pressure, serum creatinine, serum K and spot urine protein/creatinine were measured at the beginning and end of each study period. The study was started in May of 2003 and completed in May 2006.
The primary objective of this study is to identify whether cardiovascular complication rates are lower in patients who participate in managed diabetes care, in comparison to provincial and national rates. This study will involve an electronic medical record (EMR) chart audit, augmented by a manual review of hospital and other pertinent medical records, as necessary.
Recent data show that Rosiglitazone treatment can reduce proteinuria in diabetic patients. However, currently there are no trials that examine the effects of Rosiglitazone on kidney disease progression, that is, doubling of serum creatinine or time to onset of end-stage renal disease, in patients with diabetic nephropathy. We decided to study retrospectively the possible association between rosiglitazone use and clinical course of diabetic nephropathy, including rate of deterioration of renal function, appearance and progression of microalbuminuria/proteinuria, survival and acceptance to renal replacement therapy.
Diabetic nephropathy (DN) is a chronic diabetic complication and affects up to 40% of patients. The first line treatment for DN is angiotensin blockers drugs that are used to reduce the protein concentration in urine.Previous data showed that this protein, namely albuminuria, could also be reduced in a short term-period by the replacement of red meat in the diet with chicken. The aim of this study is to compare the effects of this chicken diet with enalapril on albuminuria in a long-term period( 12 months)in type 2 diabetic patients.
