Active clinical trials for "Diabetic Nephropathies"

Diabetes mellitus (DM) is a metabolic disorder commonly encountered by the healthcare professionals. Diabetic nephropathy is one of its complications, which is becoming the most common cause of end-stage renal failure in Hong Kong. As of March 31, 2000, a total of 1026 patients with diabetes were on renal replacement therapy and the number is steadily increasing. According to ADA guidelines, screening for diabetic nephropathy should be performed on an annual basis to assess urine albumin excretion rate. Serum creatinine should also be measured in all diabetic patients regardless of the degree of urine albumin excretion rate. Timed urinary collection can be a cumbersome procedure for patients and a simpler and fast test that maintains reasonable sensitivity is called for. A tool that is non-invasive and able to identify patients with early nephropathy changes would be valuable. The skin has been found to have the potential to provide an important non-invasive route for diagnostic monitoring of human subjects for a wide range of applications. eZscan® technology is a patented active electrophysiological technology which uses low level DC-inducing reverse iontophoresis, together with chronoamperometry, to evaluate the behaviour of the tissues in specific locations of the body. This non invasive test is a potential tool for the screening for diabetic nephropathy. The aim of this study is to compare eZscan with the standard methods of screening for diabetic nephropathy in patients with type 2 diabetes mellitus.

Background: Today diabetic nephropathy is a frequent, and the most lethal and costly complication of diabetes. Although treating blood pressure with agents blocking renin angiotensin system has improved outcome, the prognosis is still poor and no new interventions have been successful during the past decade. There is an urgent need for discovery of new pathways behind the development and progression of diabetic nephropathy as well as of biomarkers which can identify subjects at risk of developing adverse events. Objective: By using a multidimensional 'omics' approach, we aim to search for novel proteins, metabolites and pathways that will point to the putative new mechanisms which underlie the early renal decline. Design: Cross-sectional study, with long-term register-based follow-up. Study population: 160 patients with type 1 diabetes recruited from Steno Diabetes Center Copenhagen stratified based on stage of diabetic kidney disease, and 50 healthy non-diabetic controls. Endpoints: Primary endpoint: Glycocalyx thickness, assessed as perfused boundary region. Secondary endpoints: Gut microbiome characterisation and markers of gastrointestinal inflammation, autonomic and periphery neuropathy, urine and plasma Flow Cytometry Analysis (FACS), metabolomics and proteomics in plasma and urine, and other potential biomarkers.

We want to investigate the effects of pioglitazone on cardiovascular events in Japanese patients with type 2 diabetes.

Diabetes kidney disease (DKD) is the leading cause of end stage renal disease (ESRD) in western countries and its incidence is worryingly increasing worldwide. Cardiovascular disease shows a continuous relationship with declining of renal function in type 2 diabetes patients. Moreover, there is a strong evidence of all-cause mortality risk excess even in patients with early stages kidney disease. MicroRNA (miRNA) are small non-coding RNA molecules, containing 21-25 nucleotides, that modulate post-transcriptional gene expressions. In the past years many human miRNAs involved in the pathogenesis of renal disease have been discovered, such as miR-192, miR-194, miR-204 and miR-25. Among these, miR-192 and miR-25, are receiving greater attention while it seems that they play a role in glomerulosclerosis and renal fibrosis. However too few data are available in large publish trials among patients with renal impairment and the role of serum and urinary levels of miR-192 and miR-25 in people with preserved renal function remain unclear. To evaluate the association between serum and urinary expression of miR-192 and miR-25 and renal function (according to different extent of renal impairment) in patients with or without type 2 diabetes.

Background: Diabetes, and especially diabetic kidney disease is associated with the development of cardiovascular disease such as calcification in the coronary arteries and heart failure. Sleep apnea is frequent among patients with diabetes and diabetic kidney disease and sleep apnea itself is a solitary risk factor in the development of cardiovascular disease. Nonetheless, sleep apnea is underdiagnosed in diabetes patients because of a discrepancy between sleep apnea severity and actual oxygen deficiency symptoms which makes the diagnosis difficult. For that reason, many diabetics have undiagnosed sleep apnea together with cardiovascular disease. Early discovery of sleep apnea among high risk diabetic patients may therefore be considered crucial before cardiovascular complications develop. For this reason, sleep apnea screening of high-risk diabetics can possibly improve early diagnostics of cardiovascular disease. Aim: This study will seek to establish the association between obstructive sleep apnea (OSA) and coronary calcification and heart failure in patients with diabetic kidney disease. The basic hypothesis of the study is that patients with diabetic kidney disease and concurrent OSA have a higher prevalence and severity of coronary calcification and heart failure compared to patients without OSA. Methods: Diabetic adult patients with scheduled check-ups at Steno Diabetes Center Aarhus, or Department of Renal Medicine on Aarhus University Hospital will be included in the study. Firstly, all included patients are screened for sleep apnea with the devices SomnoTouch® and ApneaLink®. Based on the sleep apnea determination; 40 patients with moderate-severe sleep apnea are compared with 40 patients without sleep apnea. In both groups, the patients are examined for calcification in the coronary vessels using a CT-scan while the function of the heart is examined by ultrasound (echocardiography). The stiffness of aorta is measured and performed using radial artery tonometry (SphygmoCor®). Furthermore, range of blood- and urine samples will be performed The perspectives are that patients with diabetes should be regularly evaluated for sleep apnea and that patients with moderate/severe sleep apnea should undergo further examination for cardiovascular disease even though the patients don't display any symptoms of either cardiovascular disease or sleep apnea.

Microvascular complications are a major complication of diabetes.Diabetic microvascular complications can not only lead to chronic kidney disease and retinopathy, but also affect the quality of life of patients with diabetic nephropathy, which can lead to the death of diabetic patients.Due to diabetes patient survival for decades, in spite of more than 90% of time is a life outside the hospital, so the analysis of the effect of outside risk factors for complications of hospital and progress, and to find effective intervention measures is of great significance for the prevention and control of diabetic microvascular complications.Therefore, we use of advanced Internet technology, and analysis of large data algorithms, and try to keep track of routine indicators such as the patient's urine in real time in patients' families. This topic mainly observe movement (step 6000 steps per day or 6000 / week) in patients with type 2 diabetic kidney disease microvascular end point events, provide the basis for prevention and control of diabetes kidney complications, clinical significance and treatment prospects.

About 30 to 40% of patients suffering from type I diabetes are at risk of developing a diabetic nephropathy (DN) leading more or less rapidly to an end-stage renal disease. Nowadays, the microalbuminuria is the most often used clinical parameter for possible onset of DN. However, it is a late (because it permits to detect a renal disease already present), non-specific and low sensitive biomarker. Therefore the main objective of this study is to identify early urinary biomarkers predictive of DN in children with type I diabetes, before the appearance of a microalbuminuria.

Objectives: Preventing diabetic foot problems (DFP) and associated consequences, such as amputation, is a critical in rural regions. The objective is to present on the association of non-invasive DFP assessment tools and physiological indicators for the early detection of DFP among rural cases of diabetes in Taiwan.

This is a study with 2 parts. Part 1 comprises a visit to collect biological samples necessary for the molecular characterization of chronic kidney disease. Part 2 comprises an observational period of 5 visits over a period up to 8 weeks. During Part 2, baseline tests will be conducted, and urine will be collected approximately every 2 weeks for 8 weeks. Patients may participate in Part 1, Part 2, or both, and will be followed for up to 1 year consisting of data collection from the patient's medical records and home collection of urine samples every 4 months.

Diabetes is the leading cause of end-stage renal disease in developed countries. Hypertension and metabolic control are known to affect the progression of renal deficiency and patient's outcome. Our project aims at implementing a multidisciplinary and systematic approach of diabetic patients with renal deficiency, and at evaluating the impact of metabolic and blood pressure targets as recommended by current guidelines.
