A GIANT ANEURYSM OF PROPER HEPATIC ARTERY IN A CRYOGLOBULINEMIC PATIENT ON HEMODIALYSIS: A CASE REPORT.

2014

Introductrion. Hepatic artery aneurysms (HAAs) are unusual vascular lesions often associated with many different pathological conditions. Most of reported cases are described in association with connective tissue diseases, such as polyarteritis nodosa and systemic lupus erythematosus. Case report. We observed a 52-year-old man with hypertension and HCV-related cryoglobulinemia complicated by end stage renal disease on replacement therapy by hemodialysis. He was admitted to our hospital because of the worsening of blood pressure values (170/110 mmHg) associated to new onset abdominal pain. After an initial physical examination, that showed a periumbelical bruit associated to a pulsatile mass…

BRUGADA PATTERN IN HEROIN ADDICTION: SYNDROME OR PHENOCOPY?

2020

Brugada phenocopies (BrPs) are clinical entities that show an electrocardiogram (ECG) pattern similar to what is observed in Brugada syndrome (BrS). They are caused by different clinical conditions. We describe a case of BrP in a man that developed acute kidney failure secondary to rhabdomyolysis, after heroin addiction. His initial ECG showed Brugada type 1 pattern resolved after hemodialytic treatment. A provocative test with ajmaline, which resulted negative, was performed to confirm the diagnosis. BrPs can mimic a true BrS and a fast recognition of these clinical and electrocardiographic findings may avoid diagnostic mistakes thus preventing unnecessary or inaccurate treatmen

INVERSE RELATIONSHIP BETWEEN CHOROIDAL THICKNESS AND SUBCLINICAL RENAL DAMAGE IN ESSENTIAL HYPERTENSION

2018

The introduction in last years of advanced techniques of optical coherence tomography (OCT) has greatly increased our understanding of the choroid, that is the most important vascular layer of the eye. Our study was aimed to assess choroidal thickness by using Swept-Source OCT (SS-OCT) in essential hypertensive patients (EHs) with and without subclinical renal damage (SRD). We enrolled 100 EHs of which 65 without kidney damage and 35 with SRD. In all the participants SS-OCT and a routine biochemical workup were performed. Glomerular filtration rate (GFR) was estimated by the CKD-EPI equation (eGFR). SRD was defined, by the presence of microalbuminuria or eGFR between 30 and 60 mL/min/1.73 m…

SUBCLINICAL RENAL DAMAGE IS ASSOCIATED WITH A REDUCED CHOROIDAL THICKNESS IN PATIENTS WITH PRIMARY HYPERTENSION

2018

Objective: The retina is considered the easiest accessible window to study the state of the systemic microcirculation, even if the choroid is the most important vascular layer of the eye. Our understanding of the choroid has been greatly increased in last years since the introduction of advanced techniques of optical coherence tomography (OCT). Our study was aimed to assess choroidal thickness by using Swept-Source OCT (SS-OCT) in essential hypertensive patients (EHs) with and without subclinical renal damage (SRD). Design and method: We enrolled 100 EHs of which 65 without kidney damage and 35 with SRD. In all the participants SS-OCT and a routine biochemical work-up were performed. Glomer…

PLASMA ENDOTHELIN-1 IS ASSOCIATED WITH AORTIC STIFFNESS IN ESSENTIAL HYPERTENSION

2011

Background: Experimental studies documented that endothelin-1 (ET-1) contributes to arterial stiffness and recently, in patients with chronic kidney diseases, it has been observed that selective endothelin-A receptor antagonism reduces arterial stiffness, in part independently of blood pressure lowering. Little is known about the relationships between ET-1 plasma levels and aortic distensibility in subjects with essential hypertension. Objective: The aim of our study was to analyse the relationships between plasma concentrations of ET-1 and carotid-femoral pulse wave velocity (c-f PWV), as an index of aortic stiffness, in a group of hypertensive patients without overt renal insufficiency [e…

Effects of amlodipine on renal haemodynamics in mild to moderate hypertensive patients. A randomized controlled study versus placebo. Eur J Clin Phar…

1993

In this study the efficacy and safety of short-term amlodipine administration on renal haemodynamics were evaluated in mild to moderate hypertensive subjects. Our final goal was to evaluate whether the reduced blood pressure induced by treatment was associated with maintenance of renal function. After a run-in period with placebo, 30 hypertensive patients without cardiac or renal diseases were randomly allocated to a double-blind 4 weeks controlled study with amlodipine 10 mg once a day (15 patients) or placebo (15 patients). Renal haemodynamic measurements included effective renal plasma flow (ERPF) and glomerular filtration rate (GFR) by radionuclide study using 131I-hippuran and 99mTc, w…

[OP.7D.07] 24-HOUR CENTRAL BLOOD PRESSURE IS BETTER ASSOCIATED WITH TARGET ORGAN DAMAGE OF HYPERTENSION THAN BRACHIAL BLOOD PRESSURE

2017

Objective: The VASOTENS international, multicenter, observational, non-randomized, prospective study aims at evaluating the impact of 24-hour pulse wave analysis of ambulatory blood pressure (BP) recordings on target organ damage and cardiovascular prognosis of hypertensive patients. In the present analysis of study baseline data we checked whether organ damage of hypertension i) is better associated with 24-hour central than peripheral BP and ii) is related to ambulatory arterial stiffness, estimated by pulse wave velocity (PWV) and augmentation index (AIx). Design and method: In 334 hypertensive patients (mean age 53+/-15, 52% males, 45% treated) we obtained 24-hour ABPMs, echocardiograms…

DIFFERENTE IMPATTO NEI DUE SESSI DELL’OBESITÀ SULLA MASSA VENTRICOLARE SINISTRA IN SOGGETTI CAUCASICI CON IPERTENSIONE ARTERIOSA ESSENZIALE

2014

Dati non univoci sono riportati in letteratura sul ruolo della dislipidemia nello sviluppo dell’ipertrofia ventricolare sinistra. Scopo del nostro studio, è stato quello di valutare le potenziali associazioni dei principali parametri lipidici con la massa ventricolare sinistra (LVM) in pazienti con ipertensione essenziale (EHs). Abbiamo arruolato 724 soggetti con EH (età media 45±12 anni; 63% maschi), senza complicanze cardiovascolari e non trattati con farmaci ipolipemizzanti. In tutti i soggetti dono stati dosati la colesterolemia totale (Tchol), la trigliceridemia (TG) e il colesterolo HDL (HDLc). Il colesterolo LDL (LDLc) è stato stimato con la formula di Friedewald ed è stato calcolato…
