Filter by:Patients with Focal Segmental Glomerulosclerosis (FSGS) constitute an increasing proportion of the total glomerulonephritis (GN) patient cohort in North America while FSGS is a risk factor for end stage renal failure. Current non-immunological FSGS therapies include the use of angiotensin converting enzyme inhibitors (ACEi) or angiotensin II receptor blockers (ARB), to reduce intraglomerular hypertension. Unfortunately, these agents lead to incomplete renal protection. The aim of the current study is to determine whether the addition of novel sodium glucose cotransport-2 inhibitors (SGLT2i) to standard of care leads to reduced intraglomerular pressure and suppression of proteinuria. We hypothesize that combination therapy of SGLT2i drugs and conventional RAASi results in additive renal protective effects in FSGS patients. A further goal is to examine mechanisms of SGLT2 inhibition by measuring renal hemodynamic function and sodium handling. Kidney function will be assessed in FSGS patients before and after an 8 week treatment with SGLT2i dapagliflozin.
The purpose of this clinical research study is to determine whether dapagliflozin alone or in combination with saxagliptin can decrease albuminuria and improve glycemic control in patients with Type 2 diabetes, albuminuria and renal impairment (CKD). The study is planned to randomize a total of 450 patients (150 patients per treatment arm)
Vascular endothelial dysfunction increases cardiovascular (CV) risk and contributes to the progression of chronic kidney disease (CKD). Mineralocorticoid receptor (MR) antagonists have been shown to improve endothelial function, as well as decrease CV mortality and proteinuria. The specific biochemical pathways that produce these pharmacological effects for MR antagonists, however, are poorly understood. This study investigates the effect of MR antagonism on endothelial function in patients with moderate (stage III) CKD using a randomized, controlled trial. Three specific aims are proposed: Aim 1: To determine if spironolactone improves endothelial function as compared to amiloride in patients with stage III CKD; Aim 2: To determine if oxidative stress is associated with changes in endothelial function by spironolactone compared to amiloride in patients with stage III CKD; and Aim 3: To determine if endothelial dysfunction contributes to albuminuria in patients with stage III CKD. The clinical relevance is to improve understanding of the mechanisms of kidney function decline in CKD in order to develop interventions to delay or prevent dialysis, which would translate into alleviating patient suffering, caregiver burden, and health care costs.
The study is a randomised, double-blind, controlled 2 x 3 cross-over trial in which the renal effects of therapy with aliskiren (A), placebo (P) and losartan (L) will be compared. It consists of an 8-week run-in period, 8 weeks of active treatment with aliskiren or losartan (period 1), 8 weeks of active treatment with the alternative medication (period 2), and an 8-week placebo administration between them.
A recent study with the DPP-IV inhibitor Linagliptin showed an improvement in the urinary albumin creatinine ratio in patients with diabetic nephropathy. Gutzwiller et. Al. have shown that GLP-1 increases renal Na secretion and inhibits renal H secretion, further indicating some direct renal effects of GLP-1. Therefore, it seems likely that treatment with the DPP-IV inhibitor Linagliptin evolves several beneficial effects on microvascular and endothelial function beyond glucose control which most probably have an impact on the progression of renal and retinal microvascular disease. The objective of this trial is to investigate the effect of Linagliptin in comparison to placebo on the UACR in patients with high blood pressure and an increased albumin excretion. Numerous, equivalent endothelial, renal, and retinal parameters serve as objectives of the study. All study parameters will be handled in an exploratory sense for the generation of models to further discuss the role of DPP-IV inhibition on renal and retinal physiology.
The purpose of this study is to evaluate the efficacy of ASP8232 in reducing Urinary Albumin to Creatinine Ratio (UACR) in subjects with Type 2 Diabetes Mellitus (T2DM) and Chronic Kidney Disease (CKD) at 12 weeks compared to placebo.
Part 2 of the study will assess the effect of 2g of NWT-03 (an egg-white protein hydrolysate) on systolic and diastolic blood pressure and flow-mediated dilation in a crossover designed study in healthy adults with mild hypertension.
Phosphorus-based food additives are commonly used by food manufacturers for many applications, such as enhancing flavor, in ready-to-eat foods and beverages. While these additives can significantly increase an individual's daily phosphorus intake, little is known about the effect of dietary phosphorus on kidney health. In this study, the investigators will first lower baseline phosphorus intake to about 1000mg/d by educating participants to avoid foods with phosphorus additives. Then, participants will be randomized to a higher phosphorus period (~2gm/d) and a lower phosphorus period (~1gm/d) by providing unaltered, commercially-available food/beverage products with and without phosphorus additives. The investigators hypothesize that participants will have higher urine albumin excretion and fibroblast growth factor-23 (FGF-23) during the higher phosphorus period compared to the lower phosphorus period.
NADPH oxidase enzymes (NOX) have been implicated in the development of several diabetic complications including diabetic nephropathy. GKT137831 is the first in class NOX1/4 inhibitor. The primary objective of this study is to evaluate the efficacy of oral GKT137831 in patients with residual albuminuria despite maximal inhibition of the renin angiotensin aldosterone system.
The purpose of this study is to assess the effect of canagliflozin compared to placebo on progression of albuminuria in participants with Type 2 Diabetes Mellitus receiving standard care but with inadequate glycemic control and at elevated risk of cardiovascular events.
