Filter by:Thiamine is a key component in the creation of physiologic anti-inflammatory mediators. Serum thiamine stores have been found to be deficient in diabetic patients. Thiamine deficiency may be a key pathological mechanism of inflammation that results in diabetic kidney and retinal injury. The investigators hypothesize that the repletion of a patient's thiamine by oral supplementation may result in reduced inflammation, and therefore reduced kidney injury.
The study hypothesis under test is that administration of a CCR2/5 antagonist to subjects with type 2 diabetes and overt nephropathy will result in a reduction in urinary albumin, a surrogate for improved glomerular filtration.
There is no data about the effects of Renin angiotensin system blockage (RAS) on FGF23 and ADMA levels in diabetic patients with proteinuria. The aim of this study was to find out whether the beneficial effects of RAS blockage in diabetic proteinuria has any relation with the alteration of ADMA and FGF-23 levels. We searched for the effects of ACE inhibitor ramipril on the clinical and laboratory parameters of diabetic patients with proteinuria.
The VITamin D and OmegA-3 TriaL (VITAL; NCT 01169259) is a randomized clinical trial in 20,000 U.S. men and women investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or fish oil (1 gram of omega-3 fatty acids) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. This ancillary study is being conducted among participants in VITAL with a history of diabetes and will examine whether vitamin D or fish oil prevents the development and progression of diabetic kidney disease.
This is a dose ranging study to evaluate the safety and efficacy of baricitinib in the treatment of participants with mild to moderate diabetic kidney disease.
Worldwide, the most common cause of chronic kidney disease (CKD) and end stage renal disease (ESRD) is diabetes. Unlike the past, in south korea, diabetes account for more than 40% of ESRD. According to WHO reports in 1998, 100 million people had type 2 diabetes in 1997, and there is expected to increase by 300 million people in 2025. In addition, the expected survival time of patients with diabetes increase compared to previous. In the future, ESRD due to type 2 diabetes is expected to have a significant impact on the health industry. Therefore, prevention of progression to CKD and ESRD in diabetic patients is important to aspect of national health and economic problems. How to stop the progression of diabetic nephropathy is part of modern medicine to be solved. Strict glycemic control, blood pressure regulation, and use of renin-angiotensin system (RAS) blockers inhibit the development and progression of diabetic nephropathy. Microalbuminuria in diabetic patients has been recognized as a predictor of progression of diabetic nephropathy. Thus, the prevention of elevated urinary albumin excretion is an important therapeutic target for the prevention of renal and cardiovascular events. In patients with diabetes and hypertension, the drugs that block the RAS are used to treat proteinuria, but still a large number of patients with proteinuria are uncontrolled. In addition, ACE inhibitors or ARB agents actually have a limited effect on reducing the risk of cardiovascular or renal outcome. Also, sulodexide or pentoxyphylline which is reducing proteinuria have some weak evidence in terms of efficacy and safety. Therefore, the introduction of new alternative drugs are required. Already several study reported that calcitriol or paricalcitol in the renal injury model have renopreventive effect. In addition, in diabetic renal injury mice model reported that vitamin D receptor deficiency leads to glomerulosclerosis. Inhibition of the RAS with combination of paricalcitol and RAS inhibitors effectively prevent renal injury in diabetic nephropathy. Recently, Dick de Zeeuw et al reported that addition of paricalcitol to RAS inhibition safely lower residual albuminuria in patients with diabetic nephropathy. Recent studies reported that elevated concentrations of serum markers of the TNFα and Fas-pathways are strongly associated with decreased renal function in diabetic patients. However, the role of these markers in early progressive renal function decline are not clear. Therefore, the objective of this study is to identify the renoprotective effect as an new treatment of activated vitamin D (Calcitriol) indicating the TNF-α-related anti-inflammatory action and to seek the role as an important biomarker that the changes of TNFR in diabetic nephropathy can predict response to treatment.
The purpose of this study is to determine whether a very low calorie diet will stabilize or improve diabetic kidney disease.
The detrimental effects of aldostrone are not adequately arrested by the use of angiotensin converting enzyme (ACE), angiotensin II receptor blocker (ARB) or a combination of both. Recent evidence has provided robust evidence that aldostrone escape plays an important role in this regard. It is believed that aldostrone escape occurs quite commonly with reports indicating prevalence rates as high as 22% with ARBs and 40% with ACE inhibitors. In a trial of patients with diabetes and hypertension it was shown that treatment of aldostrone escape with spironolactone 25 mg daily for three months significantly reduces proteinuria. A number of other trials have similarly observed that addition of spironolactone to an ACE inhibitor based regimen provides additional benefits on proteinuria reduction, blood pressure control, and prevention of glomerular filtration rate (GFR) decline. Most of the available trials in this regard are of short duration (e.g. three months), and have added spironolactone to an ACE or ACE+ARB based regimen (the so-called triple blockade). Currently, evidence evaluating efficacy of a combined ARB+spironolactone regimen compared with conventional double RAS blockade (i.e. ACE+ARB) is lacking. Hence, this randomized open label trial was initiated to determine the effects of addition of spironolactone 25 mg daily to losartan over a period of 18 months.
This Phase 2A study is an adaptive design pilot study investigating the efficacy and safety of daily Acthar administration in diabetic patients with nephropathy and proteinuria. Patients with type 1 diabetes mellitus (T1DM) or T2DM who currently take insulin will be enrolled and randomized into 6 study groups and will be treated with either Acthar or Placebo for 36 weeks, followed by a 4 week dose taper, and a 12 week observation period. The study will compare three dose regimens of Acthar (8 U [0.1 mL], 16 U [0.2 mL], and 32 U [0.4 mL]) to equivalent volumes of Placebo to ensure the double-blind nature of the study. Insulin-requiring patients are being enrolled to aid compliance with the daily SC administration of study medication and to allow for ease of blood glucose control by adjustment of current insulin therapy in the event of glycemic excursions. Routine safety measures, including glycemic control, will be monitored throughout the study. The adaptive design component of the study allows for the re-assignment of the high dose group to the mid dose group if unacceptable toxicity is noted as per study protocol in the high dose group. Efficacy will be assessed by monitoring serum creatinine, calculated eGFR, and proteinuria (via urinary protein to creatinine ratio [PCR]). Serum cortisol concentration and additional biomarkers in blood and urine will also be monitored.
The DERENEDIAB study is a proof-of-concept, multi-center, prospective, open, randomized, controlled study of the effectiveness of renal denervation in addition to standardized medical treatment compared to medical treatment alone in diabetic subjects with diabetic nephropathy and resistant proteinuria. Bilateral renal denervation will be performed using the Symplicity Catheter - a percutaneous system that delivers radiofrequency (RF) energy through the luminal surface of the renal artery.
