Active clinical trials for "Diabetic Nephropathies"

The severity of the diabetic nephropathy is proportional to proteinuria rate and degree of renal interstitial fibrosis. Despite many treatments available today, diabetic nephropathy is responsible for a quarter of cases of end-stage renal disease (ESRD) requiring the use of renal replacement therapy or kidney transplantation. It develops as follows: chronic hyperglycemia of diabetes abyss renal glomeruli that allow proteins in the urine room. In response, the tubular epithelium produces monocyte chemoattractant protein-1 (MCP-1) that attracts monocytes circulating in the renal interstitium. Monocytes then differentiate into M1 or M2 macrophages. M1 macrophages increased MCP-1 production while M2 macrophages produce transforming growth factor beta (TGF-β) pro-fibrogenic. Renal fibrosis is negatively correlated with the glomerular filtration rate itself proportional to the number of nephrons. The decrease in the number of nephrons majorises secondarily proteinuria by the onset of focal segmental glomerulosclerosis lesions. Production of MCP-1 increases with the renal proteinuria because M1 macrophages earning kidneys reinforce the production of MCP-1, and fibrosis worsens because M2 macrophages infiltrate in turn kidneys and produce TGF -β. A way of limiting renal fibrosis would be to decrease renal monocytic infiltration by promoting the differentiation of monocytes towards macrophages M2. Although more numerous, M2 macrophages no longer benefit the kidneys because the decline of M1 macrophages decrease renal MCP-1 production. Ex vivo IL1-β orients the differentiation of monocytes towards macrophages M1 and IL-4 to M2. By cons in vivo, the differentiating factors are poorly known. It is remarkable that metformin and telmisartan increase M2 macrophages M1 macrophages and decrease, respectively, in humans and mice. Moreover, telmisartan reduces proteinuria more than losartan in diabetic nephropathy in humans and Metformin decreases the amount of TGF-β intra-renal mice. This effect of telmisartan is independent of the type 1 receptor of angiotensin II (AT1R) since it is not obtained with losartan. Telmisartan is a partial agonist of peroxisome proliferator-activated receptor gamma (PPARgamma), the working assumption is that telmisartan fosters the transition of monocytes to macrophages M2 form, and limit the recruitment of more monocytes in the kidneys and therefore proteinuria and renal fibrosis. To show this, it will be compared the ability of monocytes to differentiate ex vivo in M1 or M2 macrophages in diabetic nephropathy patients treated with losartan or telmisartan then it will characterize the role of PPARgamma in the monocyte / macrophage transition. Finally, it will be compared the urinary excretion of amino terminal propeptide of procollagen type 3 (PIIINP), considered a marker of renal fibrosis in patients receiving losartan or telmisartan.

This study will assess the preliminary efficacy of a lifestyle intervention including low-carb/ketogenic diet and exercise, enhanced by self-monitoring through health technologies on weight and diabetes outcomes (Glucose, HbA1c) and diabetic complications (cognitive function, and renal function) in a 6-month randomized clinical trial in 60 overweight/obese adults with or without T2D. Renal function will be assessed via both traditional and novel biomarkers, including novel metabolites and mitochondrial function.

This randomized study will test a behavioral intervention, based on social cognitive theory (SCT), to improve regimen adherence in three different groups of people with type 2 diabetes; (1) those with well controlled blood glucoses and no concurrent chronic renal insufficiency, (2) those with less well-controlled glucoses and no chronic renal insufficiency, and (3) those with chronic renal insufficiency regardless of glucose control. The primary aims of this study are to: (1)determine whether the intervention improves behavioral adherence to the diabetes self-management regimen including dietary adherence, physical activity, and capillary glucose self-monitoring; (2)determine whether the intervention improves clinical outcomes; (3) explore the extent to which self-efficacy is a mediator of adherence,(4) explore the extent to which the effectiveness of the intervention varies with respect to glycemic control and nephrovascular complications at baseline, and (5)explore the impact of a variety of covariates on the effectiveness of the intervention. Hypothesis #1 is that intervention group participants will perform better than attention control group participants on various measures of adherence to the diabetes management regimen. Primary adherence variables will be dietary intake, and physical activity. Hypothesis #2 is that intervention group participants will have lower HbA1c levels than attention control group participants.

Investigation of wheather addition of angiotensin receptor blocker (Irbesartan) to recommended doses of angiotensin converting enzyme inhibitor (trandolapril) is more effective in decreasing amount of protein in urine in patients with diabetic kidney disease than high doses of trandolapril.

This study is designated to evaluate the effect of a patients' educational program called DiaNe® for consultation and support people with diabetic kidney disease in an early stage. The aim of the study is to examine if the program is suitable to stop deterioration of kidney function and to maintain or improve glycemic control. The consultation and support program DiaNe® substantially contributes to a better understanding of the affected clients for this complex clinical picture, allows them for specific interventions and creates the rationale for an active therapeutic relationship.

Study of the efficacy and safety of aliskiren when added to losartan and optimal antihypertensive therapy in patients with hypertension, type 2 diabetes, and kidney disorders to monitor improvement in any of these conditions.

Diabetic kidney disease (DKD) is associated with high rates of cardiovascular events and death. In addition, DKD is the major cause of end-stage renal disease (ESRD) in the United States. The purpose of this study is to prevent progression of kidney disease among patients with DKD and uncontrolled hypertension (HTN) using a tailored, telehealth intervention that simultaneously address medication management and modifies multiple risk factors through a combination of patient self-monitoring, behavioral therapies and education to optimize adherence and self-efficacy. Additional goals are to improve control of cardiovascular disease risk factors and reduce cardiovascular events and death. We hypothesize that patients with DKD and uncontrolled HTN who receive this intervention will have less progression, or a smaller decrease in kidney function, after 3 years when compared to the education control group.

Researchers are looking for a better way to treat people who have worsening of chronic heart failure, a long-term condition where the heart does not pump blood as well as it should, as well as to treat patients who have diabetic nephropathy, a long-term, progressive decrease in the kidneys' ability to work properly in patients with diabetes mellitus. In this study researchers wanted to learn more about a new substance called finerenone (BAY94-8862). Finerenone is a substance that blocks the activation of a protein in the body called mineralocorticoid receptor (MR). An increased activation of MR is involved in the development of hypertension, organ damage and worsening of heart failure. The researchers studied how finerenone moves into, through and out of the body. The researchers also looked at how safe finerenone is and how it affects the body. The main purpose of this study was to help researchers develop recommendations for the amount of the substance (the dosing) to be given to patients with reduced liver function.

The investigators aim to investigate whether low energy shockwave therapy (LE-SWT) can preserve kidney function in diabetic patients. Participants in this study will receive LE-SWT treatment 6 times over 3 weeks. The treatment is non-invasive and has no known side effects. Previous studies have shown that LE-SWT induces angiogenesis. The investigators hypothesize that chromium-ethylenediaminetetraacetic acid (EDTA) renal clearance remains stable or increases in treated patients. Furthermore, kidney biopsy should show no signs of damage to the tissue and possibly neo-vascularization. In this project, the investigators shall also investigate LE-SWT effect on urinary markers of tubular damage and urinary nitric oxide indices. Patients' self-reported quality of life will be assessed using Short Form 36 version 2 (SF-36v2) Health Survey. There is an 18-months follow-up on patients. Only patients between 18-65 years old with moderate chronic kidney failure from diabetes will be included. This project is an interventional prospective study. 30 patients with moderate kidney failure will be recruited from the Department of Endocrinology, Odense University Hospital, Denmark. LE-SWT treatment will be performed in the ambulatory of Department of Urology. Patients will be hospitalized for 1 day in the Department of Nephrology when kidney biopsy is taken (two times in study period).
