Association of uric acid with kidney function and albuminuria: the Uric Acid Right for heArt Health (URRAH) Project

2021

Abstract Background Hyperuricemia is commonly observed in patients with chronic kidney disease (CKD). However, a better understanding of the relationship among uric acid (UA) values, glomerular filtration rate (GFR) and albuminuria may shed light on the mechanisms underlying the excess of cardiovascular mortality associated with both chronic kidney disease and hyperuricemia and lead to better risk stratification. Our main goal was to study the relationships between serum uric acid and kidney disease measures (namely estimated GFR [eGFR] and albuminuria) in a large cohort of individuals at cardiovascular risk from the URic acid Right for heArt Health (URRAH) Project database. Methods Clinica…

Hypertension in the metabolic syndrome: Summary of the new position statement of the European Society of Hypertension

2009

Arterial hypertension is often part of a larger constellation of anthropometric and metabolic abnormalities that includes abdominal (or visceral) obesity, characteristic dyslipidemia (low high-density lipoprotein cholesterol and high triglycerides), glucose intolerance, insulin resistance and hyperuricemia. Using Adult Treatment Panel III criteria, prevalence is higher than in the general population and the metabolic syndrome (MS) can be found in as many as one third of patients. In hypertensives with MS, a high prevalence of hypertension-induced target organ damage and a negative prognostic value have been described. Dietary advice and life style changes should be strongly recommended and …

Uric Acid Metabolism in Pre-hypertension and the Metabolic Syndrome

2014

In humans uric acid (UA) is the end product of degradation of purines. The handling of UA by the renal system is a complex process which is not fully understood. To date, several urate transporters in the renal proximal tubule have been identified. Among them, urate transporter 1 (URAT1) and a glucose transporter 9 (GLUT9) are considered of greater importance, as potential targets for treatment of hyperuricemia and the potential associated cardio-metabolic risk. Therefore, the recognition of the metabolic pathway of UA and elucidation of occurrence of hyperuricemia may provide important insights about the relationship between UA, pre-hypertension (preHT) and the metabolic syndrome (MetS). W…

Hyperuricemia is associated with histological liver damage in patients with non-alcoholic fatty liver disease.

2011

Background Hyperuricemia has been associated with metabolic disorders. In this line recent studies observed an independent link between higher uric acid serum levels and clinical diagnosis of non-alcoholic fatty liver disease (NAFLD). Aims We aimed to assess the potential association between uric acid serum levels and histological liver damage in a homogeneous cohort of biopsy-proven NAFLD patients. Methods Consecutive NAFLD patients (n = 166), assessed by liver biopsy (Kleiner score), anthropometric, biochemical and metabolic features, were included. Enzymatic colorimetric test was used for serum uric acid assays (Roche Diagnostics GmbH, Mannheim, Germany). Hyperuricemia was diagnosed when…

Cerebrovascular risk factors and clinical classification of strokes

2005

Cerebrovascular risk represents a progressive and evolving concept owing to the particular distribution of risk factors in patients with ischemic stroke and in light of the newest stroke subtype classifications that account for pathophysiological, instrumental, and clinical criteria. Age represents the strongest nonmodifiable risk factor associated with ischemic stroke, while hypertension constitutes the most important modifiable cerebrovascular risk factor, confirmed by a host of epidemiological data and by more recent intervention trials of primary (HOT, Syst-Eur, LIFE) and secondary (PROGRESS) prevention of stroke in hypertensive patients. To be sure, a curious relationship exists betwee…

IL28B and PNPLA3 Polymorphisms Affect Histological Liver Damage in Patients with Non-alcoholic Fatty Liver Disease.

2012

Background & Aims: Genetic background may affect liver damage in patients with non-alcoholic fatty liver disease (NAFLD). The main outcomes of the study were to assess whether IL28B rs12979860 and rs8099917 polymorphisms, together with PNPLA3 rs738409 C>G polymorphism, are associated with lobular inflammation and fibrosis, in NAFLD patients. Methods: One hundred sixty consecutive NAFLD patients were assessed by liver biopsy (Kleiner score); anthropometric, and biochemical and metabolic features were included. IL28B rs12979860 C>T, IL28B rs8099917 G>C, and PNPLA3 rs738409 C>G single nucleotide polymorphisms were tested. Results: Seventy-four (46.2%) patients had IL28B rs12979860 CC polymorph…

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…

Uric acid and uric acid/creatinine ratio and their correlations with the hemorheological determinants in subjects with subclinical carotid atheroscle…

2022

BACKGROUND AND OBJECTIVE: we have examined the concentration of serum uric acid and the serum uric acid/creatinine ratio as well as their correlations with the main determinants of the hemorheological profile in a group of subjects with subclinical carotid atherosclerosis. METHODS: we evaluated the concentration of serum uric acid and the serum uric acid/creatine ratio in 43 men and 57 women [median age 66.00 (25)] with subclinical carotid atherosclerosis, subsequently divided according to the number of traditional cardiovascular risk factors and to the insulin resistance degree. RESULTS: serum uric acid, but not the serum uric acid/creatinine ratio, results strongly influenced by the numbe…
