Prevalence and clinical characteristics of patients with true resistant hypertension in central and Eastern Europe
2013
Objective Scanty information is available on the clinical characteristics of resistant hypertension in Central and East European countries. The Blood Pressure (BP) control rate and CArdiovascular Risk profilE (BP-CARE) study allowed us to assess the prevalence and the main clinical features of resistant hypertension in this population. Design and method The study was carried out in 1312 treated hypertensive patients living in nine Central and East European countries. Results Four hundred and twenty-three patients had apparent resistant hypertension, of whom 168 had pseudo-resistant hypertension (noncompliant/white-coat) and 255 were true treatment-resistant hypertension patients (TRH). Clin…
The diagnostic performance of renal function-adjusted D-dimer testing in individuals suspected of having venous thromboembolism
2019
Renal impairment, a source of chronic hypercoagulability[1][1] and inflammation,[2][2] is known to reduce the specificity of the D-dimer test in the diagnosis of venous thromboembolism (VTE).[3][3] This leads to many false positives in such patients and consequently to additional costs, as well as
Fabry disease: overall effects of agalsidase alfa treatment
2004
Background Fabry disease is a rare X-linked disorder caused by deficient activity of the lysosomal enzyme α-galactosidase A. Progressive accumulation of the substrate globotriaosylceramide in cells throughout the body leads to major organ failure and premature death. The Fabry Outcome Survey (FOS) is a European outcomes database which was established to collect data on the natural history of this little-known disease and to monitor the long-term efficacy and safety of enzyme replacement therapy (ERT) with agalsidase alfa. This paper presents the first analysis of the FOS database on the effects of ERT on renal function, heart size, pain and quality of life. Design The effects of 1 and 2 y…
Inverse Relationship Between Ambulatory Arterial Stiffness Index and Glomerular Filtration Rate in Arterial Hypertension
2007
BACKGROUND: Arterial stiffness and mild-to-moderate renal dysfunction are predictors of cardiovascular (CV) morbidity and mortality. Recently, the ambulatory arterial stiffness index (AASI) has been proposed as a surrogate index of arterial stiffness. It has been associated with an enhanced risk of stroke. The aim of our study was to assess the relationship between AASI and glomerular filtration rate (GFR) in a group of hypertensive patients with no CV complications. METHODS: A total of 143 untreated hypertensive subjects (mean age: 44 +/- 12 years; men 57%), with serum creatinine <1.5 mg/dl, were enrolled. AASI was calculated as one minus the regression slope of diastolic on systolic blood…
Angiopoietin 2 and Neuropeptide Y are Associated with Diabetic Kidney Disease in Type 1 Diabetes Mellitus
2020
Abstract Background Serum angiopoietin 2 levels have been associated with endothelial dysfunction and diabetic kidney disease. Derangements in autonomous nervous system lead to increased production of vasoconstrictory and angiogenic mediators such as norepinephrine and neuropeptide Y and are associated with increased risk of microvascular complications. Aim To investigate associations between angiopoietin 2, neuropeptide Y and diabetic kidney disease in patients with type 1 diabetes mellitus. Methods 289 patients with type 1 diabetes mellitus duration > 1 year were included. Patients were stratified according to presence of diabetic nephropathy (macroalbuminuria, estimated glomerular fil…
Effects of Pentoxifylline on Soluble Klotho Concentrations and Renal Tubular Cell Expression in Diabetic Kidney Disease
2018
OBJECTIVE The effect of pentoxifylline on Klotho levels in patients with type 2 diabetes mellitus with chronic kidney disease (CKD) was assessed in a post hoc analysis of the Pentoxifylline for Renoprotection in Diabetic Nephropathy (PREDIAN) trial. RESEARCH DESIGN AND METHODS Circulating and urinary tumor necrosis factor-α (TNF-α) and Klotho were measured before and after 1 year of pentoxifylline. The effect on Klotho expression was assessed in cultured renal tubular cells. RESULTS Pentoxifylline administration resulted in decreased serum and urinary TNF-α, whereas serum and urinary Klotho increased significantly. Changes in urinary Klotho, urinary TNF-α, and phosphorus were associated wi…
Left ventricular hypertrophy in chronic kidney disease: A diagnostic criteria comparison.
2020
Background and aims: CKD patients have a high prevalence of LVH and this leads to an increase of cardiovascular risk. The aim of this study was to assess the prevalence of left ventricular hypertrophy (LVH) and left ventricular geometry in a group of 293 hypertensive patients with stage 2–5 chronic kidney disease (CKD), compared with 289 essential hypertensive patients with normal renal function. Methods and results: All patients underwent echocardiographic examination. Patients on stage 1 CKD, dialysis treatment, or with cardiovascular diseases were excluded. LVH was observed in 62.8% of patients with CKD and in 51.9% of essential hypertensive patients (P < 0.0001). We found increasingl…
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…
Primary megaureter in adults.
1984
The terminology of megaureters, their histological findings and etiology vary greatly in the literature. Primary obstructed megaureters must be clearly differentiated from megaureters caused by infravesical obstruction. The characterization and therapeutical consequences of the two types also differ. In a retrospective study, 43 adult patients with 54 primary obstructed megaureters (male:female = 30:13) were studied. This diagnosis excluded infravesical obstruction, reflux and neurogenic disorders. The main symptoms were flank pain, infection and hematuria. An operation was performed in 25 patients; 29 were treated conservatively. The criteria for surgery are discussed in relation to sympto…
The role of plasma triglyceride/high-density lipoprotein cholesterol ratio to predict cardiovascular outcomes in chronic kidney disease.
2015
Background Cardiovascular disease (CVD) risk is substantially increased in subjects with chronic kidney disease (CKD). The Triglycerides (TG) to High-Density Lipoprotein Cholesterol (HDL-C) ratio is an indirect measure of insulin resistance and an independent predictor of cardiovascular risk. No study to date has been performed to evaluate whether the TG/HDL-C ratio predicts CVD risk in patients with CKD. Methods A total of 197 patients (age 53 ± 12 years) with CKD Stages 1 to 5, were enrolled in this longitudinal, observational, retrospective study. TG/HDL-C ratio, HOMA-IR indexes, serum asymmetric dimethyl arginine (ADMA), high sensitivity C-reactive protein (CRP), parathyroid hormone (PT…
