Atherosclerotic renal artery stenosis (ARAS) is increasingly identified in patients with end-stage renal disease. Renal function in ARAS patients deteriorates more frequently than in nonatherosclerotic renal artery stenosis (RAS). This study was designed to test the hypothesis that atherosclerosis modifies the relationship between single-kidney hemodynamics and function and the severity of sten...

AIMS The mechanisms mediating kidney injury and repair in humans with atherosclerotic renal artery stenosis (ARAS) remain poorly understood. We hypothesized that the stenotic kidney releases inflammatory mediators and recruits progenitor cells to promote regeneration. METHODS AND RESULTS Essential hypertensive (EH) and ARAS patients (n=24 each) were studied during controlled sodium intake and...

background: atherosclerotic renal artery stenosis (aras) remains underdiagnosed due to its nonspecific demonstrations. we aimed to both estimate the frequency of aras in high-risk non-selected patients undergoing simultaneous coronary and renal catheterization and possibly identify a predictive model for aras using baseline clinical, laboratory, and coronary angiographic variables. methods: the...

Correspondence to: Dr John Main, Renal Unit, James Cook University Hospital, Marton Road, Middlesbrough TS4 3BW, UK; [email protected] _________________________ A therosclerotic renal artery stenosis (ARAS) has become topical since the development of percutaneous angioplasty and stenting. Studies defining the place for intervention have been difficult to perform and inconclusive. However, ...

BACKGROUND Delayed post-hypoxic leukoencephalopathy (DPHL) is a demyelinating syndrome characterized by neurological relapse after an initial recovery from hypoxic brain injury. We describe a patient with impaired consciousness following DPHL, concurrent with injury of the ascending reticular activating system (ARAS) shown using diffusion tensor tractography (DTT). CASE PRESENTATION A 50-year...

BACKGROUND We report on a patient who developed aggravation of excessive daytime sleepiness (EDS) concurrent with aggravation of an injured ascending reticular activating system (ARAS) following mild traumatic brain injury (TBI), demonstrated by follow-up diffusion tensor tractographies (DTTs). METHODS A 42-year-old male patient experienced head trauma resulting from flexion-hyperextension in...

The aim of this study was to investigate the risk factors associated with end-stage renal disease (ESRD) in patients with atherosclerotic renal artery stenosis (ARAS). Information about the study participants was extracted from the National Health Insurance Research Database of Taiwan for the years 1999 through 2011. We conducted this retrospective cohort study of patients with ARAS to identify...

OBJECTIVE To compare the metabolite profiles of venous effluent from both kidneys of individuals with unilateral atherosclerotic renal artery stenosis (ARAS) in order to directly examine how impaired renal blood flow impacts small-molecule handling in humans. METHODS We applied liquid chromatography-mass spectrometry based metabolite profiling to venous plasma obtained from the stenotic (STK)...

Endothelial progenitor cells (EPCs) participate in renal repair, but their number and function may be impaired by exposure to cardiovascular risk factors. The number of circulating EPCs is decreased in essential and renovascular hypertensive patients, but the effects of hypertension on EPC function are incompletely understood. We hypothesized that EPC function was preserved under well-controlle...
