Tissue hypoxia, inflammation, and loss of glomerular filtration rate in human atherosclerotic renovascular disease.

Kidney Int 2019 Apr;95(4):948-957

Division of Nephrology and Hypertension, Mayo Clinic, Rochester, Minnesota, USA. Electronic address:

The relationships between renal blood flow (RBF), tissue oxygenation, and inflammatory injury in atherosclerotic renovascular disease (ARVD) are poorly understood. We sought to correlate RBF and tissue hypoxia with glomerular filtration rate (GFR) in 48 kidneys from patients with ARVD stratified by single kidney iothalamate GFR (sGFR). Oxygenation was assessed by blood oxygenation level dependent magnetic resonance imaging (BOLD MRI), which provides an index for the levels of deoxyhemoglobin within a defined volume of tissue (R2*).

When and How Should We Revascularize Patients With Atherosclerotic Renal Artery Stenosis?

JACC Cardiovasc Interv 2019 Mar;12(6):505-517

Department of Cardiology at Ochsner Clinic Foundation, New Orleans, Louisiana.

Atherosclerotic renal artery stenosis is the leading cause of secondary hypertension and may lead to resistant (refractory) hypertension, progressive decline in renal function, and cardiac destabilization syndromes (pulmonary edema, recurrent heart failure, or acute coronary syndromes) despite guideline-directed medical therapy. Although randomized controlled trials comparing medical therapy with medical therapy and renal artery stenting have failed to show a benefit for renal artery stenting, according to comparative effectiveness reviews by the Agency for Healthcare Research and Quality, the trials may not have enrolled patients with the most severe atherosclerotic renal artery stenosis, who would be more likely to benefit from renal stenting. Because of limitations of conventional angiography, it is critical that the hemodynamic severity of moderately severe (50% to 70%) atherosclerotic renal artery stenosis lesions be confirmed on hemodynamic measurement.

Urinary mitochondrial DNA copy number identifies renal mitochondrial injury in renovascular hypertensive patients undergoing renal revascularization: A Pilot Study.

Acta Physiol (Oxf) 2019 Feb 25:e13267. Epub 2019 Feb 25.

Department of Internal Medicine, Divisions of Nephrology and Hypertension, Mayo Clinic, Rochester, Minnesota.

Aims: Patients with renovascular hypertension (RVH) exhibit elevated urinary mtDNA copy numbers, considered to constitute surrogate markers of renal mitochondrial injury. The modest success of percutaneous transluminal renal angioplasty (PTRA) in restoring renal function in RVH has been postulated to be partly attributable to acute reperfusion injury. We hypothesized that mitoprotection during revascularization would ameliorate PTRA-induced renal mitochondrial injury, reflected in elevated urinary mtDNA copy numbers and improve blood pressure and functional outcomes 3 months later.

Exp Physiol 2019 Feb 21. Epub 2019 Feb 21.

Laboratory of Stem Cell Research, Histology and Embryology Department, Biology Institute, State University of Rio de Janeiro, Rio de Janeiro, RJ, Brazil.

New Findings: What is the central question of this study? Can a single bone marrow mononuclear cell (BMMC) transplant into the subcapsular region of kidney improve cellular communication and adhesion, while restoring renal tissue cytoarchitecture and function during renovascular hypertension? What is the main finding and its importance? The BMMC transplantation restored connexin 40 expression and led to recovery of N- and E-cadherin levels within 15 days. It was observed, for the first time, that BMMC transplantation restores expression of nephrin, a component of the glomerular filtration barrier related to podocytes and the glomerular basal membrane.

Abstract: Stem cell therapy has emerged as a potential treatment for renal diseases owing to the regenerative potential of stem cells. Read More

Hydrogen Sulfide Protects Hyperhomocysteinemia-Induced Renal Damage by Modulation of Caveolin and eNOS Interaction.

Sci Rep 2019 Feb 18;9(1):2223. Epub 2019 Feb 18.

Department of Physiology, School of Medicine, University of Louisville, Louisville, KY, 40292, USA.

The accumulation of homocysteine (Hcy) during chronic kidney failure (CKD) can exert toxic effects on the glomeruli and tubulo-interstitial region. Among the potential mechanisms, the formation of highly reactive metabolite, Hcy thiolactone, is known to modify proteins by N-homocysteinylation, leading to protein degradation, stress and impaired function. Previous studies documented impaired nitric oxide production and altered caveolin expression in hyperhomocysteinemia (HHcy), leading to endothelial dysfunction. Read More

Nitric Oxide 2019 May 14;86:12-20. Epub 2019 Feb 14.

Faculty of Pharmaceutical Sciences of Ribeirão Preto, University of São Paulo, Ribeirão Preto, SP, Brazil. Electronic address:

Purpose: This study investigated the intracellular mechanisms involved in the vasodilatation induced by the classic NO donor SNP and the non-classic NO donor cis-[Ru(bpy)2(py)(NO2)](PF6) (or RuBPY) in mesenteric resistance arteries obtained from renal hypertensive (2K-1C) and normotensive (2K) rats.

Methods: On the basis of fluorimetric assays in cultured vascular smooth muscle cells (VSMCs) isolated from 2K-1C and 2K rats, we measured NO release from SNP and RuBPY, cytosolic Ca concentration ([Ca]c), and reactive oxygen species (ROS) with the selective probes DAF-2DA, Fluo-3AM and the more selective probe for peroxynitrite (7-CBA), respectively. We determined isometric tension in mesenteric arteries to assess SNP- and RuBPY-induced relaxation. Read More

Hypertens Res 2019 May 20;42(5):628-640. Epub 2018 Dec 20.

Department of Physiology, Escola Paulista de Medicina, Universidade Federal de São Paulo, São Paulo, Brazil.

The underlying mechanisms by which renal denervation (RD) decreases blood pressure (BP) remain incompletely understood. In this study, we investigated the effects of ischemic kidney denervation on different sympathetic outflows, brain and renal expression of angiotensin-II receptors, oxidative stress and renal function markers in the 2-kidney, 1-clip (2K-1C) rat model. Surgical RD was performed in Wistar male rats 4-5 weeks after clip implantation. Read More

Renal autotransplantation for the management of renal artery in-stent restenosis in an adult patient with Takayasu arteritis.

BMJ Case Rep 2018 Nov 8;2018. Epub 2018 Nov 8.

Department of Cardiology, PGIMER, Chandigarh, India.

Renovascular hypertension is a common clinical presentation in Takayasu arteritis (TA), when the renal arteries are involved. Although most of the patients respond to optimal antihypertensive drug therapy, certain patients with TA require percutaneous or surgical renal artery revascularisation to manage renovascular hypertension. We, hereby, present a 45-year-old woman, who had resistant hypertension secondary to in-stent restenosis (ISR) of renal artery stent in a single functioning kidney. Read More

Renin dependent hypertension caused by accessory renal arteries.

Clin Hypertens 2018 1;24:15. Epub 2018 Nov 1.

Department of Medicine, Sarawak General Hospital, Ministry of Health Malaysia, Jalan Hospital, 93586 Kuching, Sarawak Malaysia.

Background: Hypokalemia in the presence of hypertension is often attributed to primary hyperaldosteronism as a cause of secondary hypertension, however secondary hyperaldosteronism may present similarly. Accessory renal arteries are variants in the vascular anatomy which are often thought to be innocuous but in some circumstances can cause renovascular hypertension leading to secondary hyperaldosteronism.

Case Presentation: We report 2 cases of hypertension with secondary hyperaldosteronism associated with accessory renal arteries. Read More

Predictors of confirmatory test results for the diagnosis of primary hyperaldosteronism in hypertensive patients with an aldosterone-to-renin ratio greater than 20. The SHRIMP study.

Hypertens Res 2019 Jan 6;42(1):40-51. Epub 2018 Nov 6.

Department of Cardiology and Nephrology, Mie University Graduate School of Medicine, 2-174 Edobashi, Tsu, Mie, 514-8507, Japan.

It remains unknown which surrogate markers can predict diagnostic test results for primary hyperaldosteronism (PA). The Secondary Hypertension Registry Investigation in Mie Prefecture (SHRIMP) study has sequentially and prospectively recruited 128 patients with hypertension with an aldosterone-to-renin ratio (ARR) greater than 20, evaluated the differences among essential hypertension (EHT), idiopathic hyperaldosteronism (IHA), and aldosterone-producing adenoma (APA), and analyzed the predictors for the confirmatory tests. The patients underwent saline-loading, captopril-challenge, and upright furosemide-loading tests. Read More

Secondary hypertension in patients with saccular intracranial aneurysm disease: A population based study.

PLoS One 2018 31;13(10):e0206432. Epub 2018 Oct 31.

Neurosurgery of NeuroCenter, Kuopio University Hospital, and Institute of Clinical Medicine, School of Medicine, Faculty of Health Sciences, University of Eastern Finland, Kuopio, Finland.

Background: Secondary hypertension is a serious form of hypertension, involving 5% to 10% of all hypertension patients. Hypertension is a risk factor of the saccular intracranial aneurysm (sIA) disease and subarachnoid hemorrhage from ruptured sIA (aSAH), but the impact of secondary hypertension on sIA disease is poorly known. In a defined Eastern Finnish sIA population we studied the prevalence of secondary hypertension and its impact on sIA disease phenotype. Read More

Vitamin D Deficiency Aggravates the Renal Features of Moderate Chronic Kidney Disease in 5/6 Nephrectomized Rats.

Front Med (Lausanne) 2018 10;5:282. Epub 2018 Oct 10.

Laboratorio de Investigacao Medica 12 (LIM12), Hospital das Clinicas HCFMUSP, Faculdade de Medicina, Universidade de São Paulo, São Paulo, Brazil.

The pathogenesis of chronic kidney disease (CKD) involves a very complex interaction between hemodynamic and inflammatory processes, leading to glomerular/vascular sclerosis, and fibrosis formation with subsequent evolution to end-stage of renal disease. Despite efforts to minimize the progression of CKD, its incidence and prevalence continue to increase. Besides cardiovascular diseases and infections, several studies demonstrate that vitamin D status could be considered as a non-traditional risk factor for the progression of CKD. Read More
