Non-alcoholic fatty liver disease fibrosis score and preclinical vascular damage in morbidly obese patients.

Background: Non-alcoholic fatty liver disease (NAFLD) is strongly related with enhanced morbidity and mortality from cardiovascular disease. In obese patients with both NAFLD and features of the metabolic syndrome, the cardiovascular risk is further increased.

Aim: The aim of this study is to investigate the relationship between severity of liver fibrosis evaluated by NAFLD fibrosis score (NAFLD-FS), Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), other obesity-related markers and preclinical atherosclerosis in morbidly obese patients with previously diagnosed NAFLD.

Systemic inflammation and imbalance between endothelial injury and repair in patients with psoriasis are associated with preclinical atherosclerosis.

Background: Systemic inflammation and imbalance between endothelial injury and repair, the latter referred to as vascular incompetence, are associated with atherosclerosis and cardiovascular risk. Psoriasis, an inflammatory disease of the skin, has been associated with atherosclerosis. We investigated whether, in psoriasis, inflammation and vascular incompetence are associated with carotid intima-media thickness (cIMT) irrespective of metabolic syndrome and other established cardiovascular risk factors.

Insulin resistance and not BMI is the major determinant of early vascular impairment in patients with morbid obesity.

Aim: Several factors contribute to the development of atherogenesis in patients with obesity. The aim of our study was to evaluate the different roles of insulin resistance, strictly correlated to visceral adiposity, and the body mass index (BMI), an estimate of overall adiposity, on early vascular impairment in patients with morbid obesity.

Methods: We enrolled 65 morbidly obese subjects (BMI 44.

On-treatment C-reactive protein and HDL cholesterol levels in patients at intermediate cardiovascular risk: impact on carotid intima-media thickness.

Aims: Statin therapy is followed by reductions in carotid intima-media thickness (CIMT) and C-reactive protein (CRP) levels, but a significant number of treated patients still have increased CIMT. We investigated whether on-treatment levels of CRP are associated with CIMT in hypercholesterolemic patients receiving statin therapy. The influence of blood pressure and anti-hypertensive therapy on the association between CRP and CIMT was evaluated.

Human endothelial impairment in sepsis.

The onset of sepsis is often non-specific, and its severity is cryptic. The pathophysiological mechanism of sepsis development involves vascular alteration and, in particular, the impairment of endothelial function. Aim of the study was to evaluate the potential implications of brachial endothelial function assessment in patients affected by Gram-negative sepsis.
