Serum uric acid is not independently associated with plasma renin activity and plasma aldosterone in hypertensive adults

2017

Background and Aims In experimental investigations conducted in rats, raising serum uric acid (SUA) levels resulted in the stimulation of intrarenal renin expression. Studies in humans exploring the association of SUA with plasma renin activity (PRA) yielded conflicting results. Moreover, little is known about the relationship of SUA with plasma aldosterone concentration (PAC). The study aimed to assess the relationship between SUA levels, PRA, and PAC and the influence of age, gender, body mass index (BMI), and hyperuricemia on these relationships in subjects with essential hypertension (EH). Methods and Results We enrolled 372 hypertensive patients (mean age 45 ± 12 years, men 67%) with u…

EFFECTS OF ALLOPURINOL ON RENAL FUNCTION DECLINE IN HYPERTENSIVE PATIENTS WITH CHRONIC KIDNEY DISEASES

2014

Aim: To evaluate retrospectively the effects of allopurinol treatment on renal function decline in non-gouty hypertensive patients with moderate-to-severe CKD. Methods: We selected 22 patients treated with allopurinol (A) (100–300 mg/die) that were compared with 44 subjects not treated with this drug (B), matched with A for estimated glomerular filtration rate (eGFR), age, gender and blood pressure values. Results: After a mean follow-up period of 16 months no significant difference was observed between the two groups regarding eGFR decline (A: -6.8 ± 11.6 ml/min/1.73 m2; B: -4.2 ± 9.3 ml/min/1.73 m2). Furthermore, the percentage of subjects with a value of eGFR reduction above the median w…

Endothelin-1 and F2-isoprostane relate to and predict renal dysfunction in hypertensive patients.

2008

Background. Hypertension and additional non-traditional risk factors can damage the kidney directly and by promoting atherogenesis. Evidence indicates that increased oxidative stress and inflammation may mediate a large part of the effects of risk factors on the kidney. We hypothesized that in hypertensive patients (HT), oxidative stress, measured as 8-ISO-prostaglandin F2alpha (8-ISO-PGF2alpha), should raise paralleling decreasing renal function and should correlate with estimated glomerular filtration rate (eGFR). Methods. In 626 HT with renal function ranging from stages 1 to 5 and 100 healthy controls, plasma levels of 8-ISO-PGF2alpha, high-sensitivity C-reactive protein (CRP), transfor…

Polymorphonuclear leukocyte integrins in chronic renal failure

2005

Patients with chronic renal failure (CRF), in comparison with general population, show a higher cardiovascular mortality, not fully explained by the "traditional" risk factors. Among the new factors that have been hypothesized, leukocytes might play an important role. In a group of patients with mild CRF we determined, at baseline and after in vitro activation with 4-phorbol-12-myristate-13-acetate (PMA) and N-formyl-methionyl-leucyl-phenylalanine (fMLP), the polymorphonuclear leukocytes (PMN) beta2-integrin pattern (CD11a, CD11b, CD11c and CD18) by using indirect immunofluorescence with a flow cytometer. At baseline we observed an increase in the phenotypical expression of CD11b, CD11c and…

Relation of oxidant stress with endothelial activation in hemodialysis.

2006

Introduction and Aims: Enhanced oxidative stress may be implicated in the pathogenesis of atherosclerosis in hemodialysed patients (HDs). We hypothesized that in hypertensive HDs oxidative stress should be elevated and associated to endothelial activation, and inflammation. Methods:We examined oxidative stress, as measured by 8-ISO-PGF2alpha, endothelial activation by measuring endothelin-1 (ET-1) and adhesion molecules ICAM-1 and VCAM-1, and the biomarker of acute-phase inflammation CRP. In 52 mild HDs and in 50 healthy controls (Cs) we analysed, in the interdialytic day, plasma levels of 8-ISO-PGF2alpha, ET-1, ICAM-1 and VCAM-1, and high sensitivity CRP.

Average real variability of 24-h systolic blood pressure is associated with microalbuminuria in patients with primary hypertension.

2015

Limited and conflicting data are available about the association between short-term blood pressure (BP) variability and urinary albumin excretion rate (uAER). The objective of our study was to analyze the relationships between microalbuminuria (MAU), defined as an uAER between 20 and 200 μg min(-1), and short-term BP variability (BPV), assessed as average real variability (ARV), weighted s.d. of 24-h BP and as s.d. of daytime and night-time BP. The study population consisted of 315 untreated essential hypertensives with normal estimated glomerular filtration rate (>60 ml min(-1) per 1.73 m(2)), who underwent 24-h ambulatory BP monitoring and 24-h uAER determination.

SUMMARY: Aim: Parathyroid hormone secretion is mainly influenced by hypocalcaemia, hyperphosphataemia and vitamin D deficiency. However, previous in vitro and in vivo studies showed that endothelin-1 can influence parathyroid hormone secretion. This study was aimed at evaluating this relationship in vivo in uraemic patients. Methods: Parathyroid hormone and endothelin-1 plasma concentrations were measured in 67 haemodialysed patients. Patients with history of cardiovascular diseases and those with parathyroid adenoma were excluded. Results: Plasma levels of endothelin-1 were found to be inversely related to those of parathyroid hormone (P < 0.04) The multiple regression analysis, carried ou…

Background and aims: Clinical studies exploring the relationship between serum uric acid (SUA) and arterial stiffness yielded conflicting results. Only in a few of these studies, arterial distensibility was examined by measuring aortic pulse wave velocity (PWV), which is considered the gold standard for evaluating arterial stiffness. In none of the previous investigations was the influence of SUA on aortic distensibility assessed, taking into account the effect of albuminuria. The purpose of our study was to comprehensively analyse the relationships between SUA and aortic PWV in a group of essential hypertensive patients.

Oxidative stress and inflammation in long-term renal transplanted hypertensives.

2006

INTRODUCTION Several studies have shown that chronic renal failure (CRF) is characterized by "accelerated atherosclerosis". More recent studies emphasize that inflammation and oxidative stress play a central role in atherosclerosis, and it is well-established that C-reactive protein (CRP) is a cardiovascular risk marker in the general population, in end-stage renal disease (ESRD) patients and in allograft recipients. METHODS We measured the serum concentration of high sensitivity CRP, TNFalpha, 8-iso-prostaglandin F2alpha (8-iso-PGF2alpha, an in vivo oxidative stress marker) in 15 CRF patients and in 15 transplant recipients. Exclusion criteria were age 65 years, smoking, diabetes mellitus …

Recentemente è stata valutata la prevalenza della disfunzione renale in pazienti ipertesi senza complicanze cardiovascolari o patologia renale nota, partecipanti allo studio Renal Dysfunction in Hypertension (REDHY), utilizzando quattro metodi di stima del filtrato glomerulare (GFR): la clearance della creatinina (CrCl), l’equazione semplificata dello studio Modification of Diet in Renal Disease (MDRD), la formula di Cockcroft-Gault (CG) e l’equ…

FOKI AND BSMI VITAMIN D RECEPTOR GENE POLYMORPHISMS, ARE THEY ASSOCIATED WITH INTIMA MEDIA THICKNESS IN ESSENTIAL HYPERTENSIVE INDIVIDUALS

2015

Objective: Analyzing 25hydroxyvitaminD (25[OH]D) serum levels and common carotid intimamedia thickness (IMT) relationship, and evaluating the association of FokI and BsmI vitamin D receptor (VDR) gene polymorphisms with IMT in essential hypertensive patients were our study aims. Design and method: We enrolled seventyone essential hypertensive patients, 18–75 years old. Patients underwent clinical blood pressure (BP) measurement, 24 hour ambulatory blood pressure monitoring, routine blood test, 25[OH]D assay and common carotid IMT evaluation. FokI and BsmIVDRpolymorphisms were analyzed by polymerase chain reactionrestriction fragment length polymorphism (PCRRFLP).

The Relationship Between Aortic Root Size and Hypertension: An Unsolved Conundrum

2017

Thoracic aortic aneurysms rupture and dissection are among the most devastating vascular diseases, being characterized by elevated mortality, despite improvements in diagnostic imaging and surgical techniques. An increased aortic root diameter (ARD) represents the main risk factor for thoracic aortic dissection and rupture and for aortic valve regurgitation. Even though arterial hypertension is commonly regarded as a predisposing condition for the development of thoracic aorta aneurysms, the role of blood pressure (BP) as determinant of aortic root enlargement is still controversial. The use of different methods for indexation of ARD may have in part contributed to the heterogeneous finding…

Relationship between Plasma Aldosterone and Left Ventricular Mass in Hypertensive Subjects with Mild-to-Moderate Chronic Kidney Disease

2011

Introduction: Plasma aldosterone (ALD) levels are generally increased in subjects with chronic kidney disease (CKD), especially in those with end-stage renal disease. Convincing clinical and experimental data indicate that aldosterone plays a fundamental role in determining functional and structural changes of the heart. On the other hand, it is known that hypertensive patients with renal dysfunction, also of mild degree, show an increased prevalence of cardiovascular organ damage. Little is known about the relationships between aldosteronaemia and left ventricular mass in subjects with mild-to-moderate CKD. Aim: To analyse the relationships between ALD and left ventricular mass (LVM), in a…

RELATIONSHIP BETWEEN ASYMPTOMATIC HYPERURICEMIA AND RENAL FUNCTION DECLINE IN HYPERTENSIVE SUBJECTS.

2013

Introduction: It is well known that the deposition of uric acid crystals exert direct toxic effect on the renal parenchyma and vasculature. Both experimental and some clinical studies suggest the possibility that an increased uric acid level can lead to kidney disease even without deposition of uric acid crystals. However, other studies yielded conflicting results, especially regarding the role of uric acid in the progression of established kidney disease. Aim: To evaluate retrospectively the relationship between asymptomatic hyperuricemia and renal function decline in non-gouty hypertensive patients. Methods: We enrolled 97 hypertensive subjects, 48 with chronic kidney diseases (CKD) and 4…

CORRELAZIONE TRA ALDOSTERONE E PARATORMONE PLASMATICI NELL’IPERTENSIONE ARTERIOSA ESSENZIALE

2013

Studi sperimentali e clinici hanno indotto ad ipotizzare una interazione fisiopatologica tra aldosterone (PAC) e paratormone (PTH) nello sviluppo dell’ipertensione arteriosa e delle alterazioni cardiovascolari . Scopo di questo studio è stato di valutare il rapporto tra PAC e PTH nell’ipertensione essenziale (EH) e le eventuali interazioni con FGF23, proteina modulatrice della secrezione di PTH. In 105 H ed in 50 controlli sani sono stati analizzati i livelli plasmatici di PAC, PTH, FGF23 Vitamina D. L’analisi di correlazione multipla condotta considerando PAC come variabile dipendente ha mostrato una correlazione di PAC con FGF23 (β = 0.337; p = 0.0021) e con PTH (β = 0.241; p = 0.039) ind…
