Prediction of Acute Glomerular Filtration Rate Reductions Following Renin-angiotensin System Blockade in Chronic Kidney Disease: A Possible Application of Ultrasonography in Clinical Practice.

Numai utilizatorii înregistrați pot traduce articole

Objective Renal arteriolosclerosis is a risk factor for acute reductions in the glomerular filtration rate (GFR) when renin-angiotensin system (RAS) inhibitors are administered. Renal arteriolosclerosis can be detected by an increase in the resistive index (RI) on Doppler ultrasonography. The

Large blood pressure variability aggravates arteriolosclerosis and cortical sclerotic changes in the kidney in hypertensive rats.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND It has been shown that increased short-term blood pressure (BP) variability (BPV) aggravates hypertensive cardiac remodeling in spontaneously hypertensive rats (SHRs) through a cardiac angiotensin II (angII) system. However, little was known about the renal damage induced by large BPV.

PP085. Angiotensin II type 1 receptor antibodies increase angiotensin II sensitivity in pregnant rats.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Pregnant women who subsequently develop preeclampsia are highly sensitive to infused angiotensin (Ang) II; the sensitivity persists postpartum. Activating autoantibodies against the Ang II type 1 (AT1) receptor are present in preeclampsia. In vitro and in vivo data suggest that they could

Angiotensin II type 1 receptor antibodies and increased angiotensin II sensitivity in pregnant rats.

Pregnant women who subsequently develop preeclampsia are highly sensitive to infused angiotensin (Ang) II; the sensitivity persists postpartum. Activating autoantibodies against the Ang II type 1 (AT(1)) receptor are present in preeclampsia. In vitro and in vivo data suggest that they could be

Systemic small-vessel disease is not exclusively related to lacunar stroke. A pilot study.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Lacunar infarcts usually results from a vasculopathy of the small vessels of the brain. It is not known whether this small-vessel disease is exclusively related to the brain or part of a more systemic small-vessel disease. In this study, patients with a lacunar stroke were investigated for

Normoalbuminuric chronic kidney disease in diabetes.

Numai utilizatorii înregistrați pot traduce articole

Urinary albumin excretion (UAE) is widely used in clinical practice as indicator of diabetic kidney disease. According to the classical concept of the natural course of diabetic nephropathy, an increase in UAE usually precedes a decline in renal function. Meanwhile, a growing body of evidences

[Hypertension and arteriosclerosis].

Numai utilizatorii înregistrați pot traduce articole

Hypertension is a known risk factor for arteriosclerosis, and causes both atherosclero= sis of medium-large arteries and arteriolosclerosis of the arterioles. Elevated blood pressure causes damage to the endothelium and vascular wall through both mechanical and humoral factors. We and others have

Effect of ACE inhibition on myocardial ischaemia.

Numai utilizatorii înregistrați pot traduce articole

During ischaemia, both the circulating renin-angiotensin system and the local angiontensin converting enzyme are activated. The circulating renin-angiotensin system has a short-term role in the regulation of the cardiovascular system. Its aim is to restore blood pressure and cardiac homeostasis.

Hypertension in Chronic Glomerulonephritis.

Numai utilizatorii înregistrați pot traduce articole

Chronic glomerulonephritis (GN), which includes focal segmental glomerulosclerosis and proliferative forms of GN such as IgA nephropathy, increases the risk of hypertension. Hypertension in chronic GN is primarily volume dependent, and this increase in blood volume is not related to the

Idiopathic nodular glomerulosclerosis: three Japanese cases and review of the literature.

Numai utilizatorii înregistrați pot traduce articole

Idiopathic nodular glomerulosclerosis (ING) is characterized as diffuse nodular glomerulosclerotic lesions, closely resembling Kimmelstiel-Wilson lesions without diabetic mellitus. We report here three Japanese cases of ING and discuss the previous reports. The patients were 75-, 48- and 84-year-old

Idiopathic nodular glomerulosclerosis is a distinct clinicopathologic entity linked to hypertension and smoking.

Numai utilizatorii înregistrați pot traduce articole

Idiopathic nodular glomerulosclerosis (ING) is an enigmatic condition that resembles nodular diabetic glomerulosclerosis but occurs in nondiabetic patients. We reviewed clinicopathologic features, immunohistochemical profiles, and outcomes in 23 patients with ING diagnosed from among 5,073 native

Nephrotic syndrome and abdominal arterial bruits in a young hypertensive patient: a case report.

Numai utilizatorii înregistrați pot traduce articole

We report the case of a 34-year-old black African hypertensive woman who presented with nephrotic proteinuria, mild renal failure and abdominal bruits on physical examination. The renal Doppler ultrasound revealed bilateral artery stenosis. Thoracoabdominal aortic nuclear magnetic resonance showed a

The role of uric acid in the pathogenesis of hypertension in the young.

Numai utilizatorii înregistrați pot traduce articole

Uric acid has been suspected to be a risk factor for hypertension since the 1870s. Numerous epidemiological studies demonstrate an association between uric acid and both incident and prevalent hypertension in diverse populations. Studies in elderly patients have had more variable results, raising

Quantitative ultrastructural study of afferent and efferent arterioles in IgA glomerulonephritis and benign nephrosclerosis.

Numai utilizatorii înregistrați pot traduce articole

Arteriolosclerosis frequently occurs in IgA nephritis (IgAN), and it is the hallmark of benign nephrosclerosis (BNS). The quantitative ultrastructure of juxtaglomerular arterioles is not known in these disorders. We examined afferent and efferent arterioles in renal biopsies from 25 adult patients

Two distinct FSGS lesions caused by distinct etiology confirmed in a single patient in pre- and post-transplantation.

Numai utilizatorii înregistrați pot traduce articole

At the age of three yr, a male patient had surgical treatment for bilateral vesicoureteral reflux (VUR), and at the age of 19 yr, he developed nephrotic syndrome because of focal segmental glomerulosclerosis (FSGS). His renal function deteriorated despite treatment with temocapril and aspirin, and
