Ardelyx drug reduces elevated phosphate levels, late-stage study shows

Ardelyx Inc's experimental drug has shown promise in a late-stage study as a standalone therapy to reduce elevated blood phosphate levels in patients with chronic kidney disease (CKD), the drugmaker said on Tuesday.

Abstract Daily dietary potassium (K+) intake may be as large as the extracellular K+ pool. To avoid acute hyperkalemia, rapid removal of K+ from the extracellular space is essential. This is achieved by translocating K+ into cells and increasing urinary K+ excretion. Emerging data now indicate that the renal thiazide-sensitive NaCl cotransporter (NCC) is critically involved in this homeostatic kaliuretic response. This suggests that the early distal convoluted tubule (DCT) is a K+ sensor that can modify sodium (Na+) delivery to downstream segments to promote or limit K+ secretion. K+ sensing is mediated by the bas...

Contributors : Jin He ; Zhe ZhangSeries Type : Expression profiling by high throughput sequencingOrganism : Sus scrofaBased on the dosage effect hypothesis, renal cysts could arise in transgenic murine models overexpressing either PKD1 or PKD2, which are causal genes responsible for autosomal dominant polycystic kidney disease (ADPKD). To prove whether PKD genes overexpression is a universal mechanism driving cystogenesis or is merely restricted to rodents, other animal models are required. Previously, we failed to observe any renal cysts in a PKD2 overexpression transgenic pig model partially due to epigenetic silencing o...

Albuminuria acts as a marker of progressive chronic kidney disease and as an indicator for initiation of hypertension treatment via modulation of the renin-angiotensin-aldosterone system with angiotensin receptor blockers or angiotensin-converting enzyme inhibitors. However, the true significance of albuminuria has yet to be fully defined. Is it merely a marker of underlying pathophysiology, or does it play a causal role in the progression of kidney disease? The answer remains under debate. In this issue of the JCI, Bedin et al. used next-generation sequencing data to identify patients with chronic proteinuria who had bial...

Researchers here argue that fibrosis of cardiac tissue is an important contribution to the development of atrial fibrillation in older patients. Fibrosis is a feature of many age-related conditions, a dysfunction in tissue maintenance processes that involves the generation of scar-like deposits of collagen by overactive fibroblasts. This scarring disrupts normal tissue structure and function in many organs, including the heart, and there is no good approved therapy to treat the progression of fibrosis: even slowing it is haphazard and unreliable. This may soon change. Fibrosis appears to be caused to a large degree ...

Harvesting tissue from failing kidneys and autotransplantation of expanded committed progenitors giving rise to renal parenchyma could theoretically allow for the restoration of kidney function delaying or preventing the need for dialysis or a renal allograft. Here we utilized healthy and end-stage human adult kidneys to robustly expand proliferative kidney epithelial cells and establish 3D-kidney epithelial ...

Abstract Background: Chronic kidney disease (CKD) is frequently present in patients with aortic valve disease. Decreased kidney perfusion as a consequence of reduced cardiac output may contribute to renal dysfunction in this setting. Objective: Given the potential reversibility of kidney hypoperfusion after valve repair, this study aimed to analyze the impact of percutaneous transcatheter aortic valve implantation (TAVI) on kidney function. Methods: We performed a retrospective analysis of 233 consecutive patients who underwent TAVI in a single center between November 2008 and May 2016. We assessed three groups according t...
