Filter by:Over 1.25 million Americans have Type 1 Diabetes (T1D), increasing risk for early death from cardiovascular disease (CVD). Despite advances in glycemic and blood pressure control, a child diagnosed with T1D is expected to live up to 17 years less than non-diabetic peers. The strongest risk factor for CVD and mortality in T1D is diabetic kidney disease (DKD). Current treatments, such as control of hyperglycemia and hypertension, are beneficial, but only partially protect against DKD. This limited progress may relate to a narrow focus on clinical manifestations of disease, rather than on the initial metabolic derangements underlying the initiation of DKD. Renal hypoxia, stemming from a potential metabolic mismatch between increased renal energy expenditure and impaired substrate utilization, is increasingly proposed as a unifying early pathway in the development of DKD. T1D is impacted by several mechanisms which increase renal adenosine triphosphate (ATP) consumption and decrease ATP generation. Caffeine, a methylxanthine, is known to alter kidney function by several mechanisms including natriuresis, hemodynamics and renin-angiotensin-aldosterone system. In contrast, to other natriuretic agents, caffeine is thought to fully inhibit the local tubuloglomerular feedback (TGF) response to increased distal sodium delivery. This observation has broad-ranging implications as caffeine can reduce renal oxygen (O2) consumption without impairing effective renal plasma flow (ERPF) and glomerular filtration rate (GFR). There are also data suggesting that chemicals in coffee besides caffeine may provide important cardio-renal protection. Yet, there are no data examining the impact of coffee-induced natriuresis on intrarenal hemodynamic function and renal energetics in youth-onset T1D. Our overarching hypothesis in the proposed pilot and feasibility trial is that coffee drinking improves renal oxygenation by reducing renal O2 consumption without impairing GFR and ERPF. To address these hypotheses, we will measure GFR, ERPF, renal perfusion and oxygenation in response to 7 days of cold brew coffee (one Starbucks® Cold brew 325ml bottle daily [205mg caffeine]) in an open-label pilot and feasibility trial in 10 adolescents with T1D already enrolled in the CASPER Study (PI: Bjornstad).
Higher prevalence of hypomagnesaemia in diabetic patients with nephropathy was compared to those without nephropathy. Serum magnesium levels were significantly inversely correlated with serum creatinine and U-A/C ratio, and positively correlated with glomerular filtration rate (GFR). Hence, Magnesium supplementation using magnesium salts could be a good approach to improve the cardiovascular complications, insulin resistance index, lipid profile and kidney function in diabetic nephropathy patients.
Nidufexor addresses fibrosis, oxidative stress, inflammation and cell death, and therefore has the potential to improve the management of diabetic kidney disease when added to the standard of care (SoC) (angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB)). This non-confirmatory Phase 2 study was designed to determine the safety, tolerability, efficacy, pharmacokinetics and pharmacodynamics of nidufexor in combination with ACEI or ARB at a dose level that is SoC as judged by the study doctor in patients with type 2 diabetes and nephropathy.

This study will be evaluating the safety and efficacy of propagermanium for the treatment of participants with DKD who are already taking irbesartan by: - monitoring symptoms that participants may experience while on the study, - measuring levels of protein in participant's urine and kidney function during the course of the study, - measuring the levels of propagermanium and irbesartan that enters into participant's urine and blood, and - comparing the propagermanium outcomes to participants' pre-study and placebo outcomes. Eligible participants will randomly be assigned to one of two arms to receive both the propagermanium and placebo in different orders as follows, either: Treatment Period 1 taking a propagermanium capsule twice a day for 12 weeks, followed by a six week washout period followed by Treatment Period 2 taking a placebo capsule twice a day for 12 weeks. OR Treatment Period 1 taking a placebo capsule twice a day for 12 weeks, followed by a six week washout period followed by Treatment Period 2 taking a propagermanium capsule twice a day for 12 weeks.
Background: Diabetic kidney disease (DKD), as one of chronic complication of type 2 diabetes mellitus, is common cause of end stage renal disease (ESRD). Vitamin D deficiency is known as one of DKD risk factors. Recent studies on association between vitamin D deficiency and DKD had shown conflicting results. It may be due to vitamin D receptor gene polymorphisms, which is affected by BsmI, Cdx2, ApaI, FokI, and TaqI gene. The investigators conducted cross-sectional study to investigate association between BsmI polymorphisms in vitamin D receptor gene with diabetic kidney disease Hypothesis: BsmI polymorphisms in vitamin D receptor gene is associated with diabetic kidney disease (DKD)
Over 1.25 million Americans have type 1 diabetes (T1D), increasing risk for early death from cardiorenal disease. The strongest risk factor for cardiovascular disease (CVD) and mortality in T1D is diabetic kidney disease (DKD). Current treatments, such as control of hyperglycemia and hypertension, are beneficial, but only partially protect against DKD. Hyperfiltration is common in youth with T1D, and predicts progressive DKD. Hyperfiltration is also associated with early changes in intrarenal hemodynamic function, including increased renal plasma flow (RPF) and glomerular pressure. Intrarenal hemodynamic function is strongly influenced by the renin-angiotensin-aldosterone system (RAAS), which is also considered a key player in the pathogenesis of DKD. Preliminary data demonstrate differences in intrarenal hemodynamic function and RAAS activation in early and advanced DKD in T1D. However, the pathophysiology contributing to the differences observed in RAAS activation and intrarenal hemodynamic function in T1D are poorly defined Animal research demonstrates that arginine vasopressin (AVP) acts directly to modify intrarenal hemodynamic function, but also indirectly by activating RAAS. Preliminary data suggest that elevated copeptin, a marker of AVP, which predicts DKD in T1D adults, independently of other risk factors. However, no human studies to date have examined how copeptin relates to intrarenal hemodynamic function in early DKD in T1D. A better understanding of this relationship is critical to inform development of new therapies targeting the AVP system in T1D. Accordingly, in this study, the investigators propose to define the relationship between copeptin and intrarenal hemodynamics in early stages of DKD, by studying copeptin levels, renal plasma flow, and glomerular filtration in youth (n=50) aged 12-21 y with T1D duration < 10 y.
Homocysteine levels have been found elevated in T1DM patients with Diabetic nephropathy (DN) due to several causes, including dietary deficiencies. Hyperhomocysteinemia induces renal injury and is associated with increasing urinary albumin excretion(UAE). Therefore, the investigators performed a randomized-controlled trial of oral supplementation with vitamin B complex as an adjuvant therapy for nephropathy in pediatric patients with T1DM and assessed its relation to homocysteine levels, glycemic control, microalbuminuria and cystatin C as a marker of nephropathy.
