AIMS Our study investigated reactive oxygen species (ROS) generation and angiotensin II type 1 receptor (AT(1)-R) expression in primed polymorphonuclear leukocytes (PMNs) of dyslipidaemic subjects over prolonged statin treatment. METHODS AND RESULTS Sixteen untreated dyslipidaemic subjects with moderately increased cardiovascular risk (National(More)
The renin-angiotensin system plays a key role in the regulation of cardiovascular functions and in particular angiotensin II type 1 receptor (AT1R)-operated pathways are involved in the modulation of inflammation in the vascular wall. In the present study we assessed the pattern of expression of AT1Rs on different human circulating leukocyte subsets. Venous(More)
Experimental studies demonstrated that mineralocorticoid antagonists prevent or reverse myocardial fibrosis. Therefore, we tested the hypothesis that the aldosterone antagonist canrenone can improve left ventricular diastolic function in essential hypertension. Using digitized M-mode echocardiography and 24-hour blood pressure monitoring (ABPM), we realized(More)
AIMS The aim is to make a systematic review of the literature to assess the effect of lipid-lowering drugs on venous thromboembolism (VTE) occurrence. METHODS AND RESULTS MEDLINE and EMBASE databases were searched to identify studies that evaluated the effect of lipid-lowering drugs, in particular statins and fibrates, on VTE risk until April 2009.

Treatment with statins requires close monitoring of serum creatine kinase (CK) levels to prevent myopathy, a common and potentially serious dose-dependent adverse effect of these drugs. We have investigated the correlation between elevated CK levels and polymorphisms in the genes encoding transporters involved in statin disposition. Patients with and(More)
The objective of the present study was define in a relatively large patient population with coronary artery disease (CAD) whether the concomitant presence of peripheral artery disease (PAD), which is known to convey additional cardiovascular risk, was associated with different circulating levels of sRAGE with respect to CAD alone and control subjects.(More)
OBJECTIVE The mechanisms involved in the relationship between pain perception and hypertension are poorly understood. This study has sought to investigate whether the spontaneous baroreflex sensitivity and the autonomic nervous system balance are related to hypertension-associated hypoalgesia. METHODS In the morning, 73 untreated male subjects (45(More)
BACKGROUND In diabetes, a variety of pro-inflammatory cellular changes has been found in various cell types, including monocytes which are known to be involved in all the phases of atherogenesis. Angiotensin II (Ang II) type 1 receptor (AT1R) mediates the pro-atherogenic effects of Ang II whereas the type 2 receptor (AT2R) seems associated with(More)
BACKGROUND Neutrophil (PMN) leukocytes participate to the initial phases of atherosclerosis through the release of Interleukin 8 (CxCL8; IL-8) that contribute to amplification of inflammation. Aim of the study is to investigate the production of IL-8 by PMN leukocytes from dyslipidemic patients treated with simvastatin. METHODS In 15 dyslipidemic subjects(More)
INTRODUCTION We designed a randomized, controlled prospective study aimed at comparing efficacy and tolerability of ezetimibe+fenofibrate treatment versus pravastatin monotherapy in dyslipidemic HIV-positive (HIV+) patients treated with protease inhibitors (PIs). METHODS We consecutively enrolled 42 HIV+ dyslipidemic patients on stable PIs therapy (LDL(More)
