Effetto di due vini rossi siciliani su alcuni fattori di rischio cardiovascolare
Background. The aim of this study was to evaluate whether Sicilian red wine consumption is associated with a lower cardiovascular risk.
Methods. Forty-eight subjects of both sexes (age range 35-65 years) nondrinkers or rarely drinkers of moderate red wine intake were selected. Subjects were divided into two groups (group A and group B), assigned to receive with a crossover design 250 ml/die (during the meals) of one of two types of Sicilian red wines (Nero d’Avola and Etna Torrepalino respectively). At all visits (-15 days, basal, +4 and +8 weeks) the following parameters were measured: blood glucose, total cholesterol and triglycerides (by enzyme kit methods, Boehringer Mannheim, Milan, Italy), HDL cholesterol (by selective precipitation with dextran-magnesium chloride), LDL cholesterol (by calculation with the Friedewald formula), LDL/HDL ratio, apolipoproteins A1 and B (by radial immunodiffusion, Behring Institute, Scoppito, Italy), lipoprotein(a) (ELISA, Technoclone, Vienna, Austria), plasma C-reactive protein (high-sensitivity, Dade Behring, Marburg, Germany), D-dimer (Turbiquant, Dade Behring), factor VII (coagulant activity, Dade Behring), plasminogen activator inhibitor antigen (ELISA), tissue-type plasminogen activator antigen (ELISA), fibrinogen (coagulant), oxidized LDL antibody (ELISA), total plasma antioxidant capacity (FRAP method).
Results. At the end of the red wine intake period, HDL cholesterol was significantly increased (p< 0.01) and the LDL/HDL ratio was significantly decreased (p < 0.05) in both study groups, while apolipoprotein A1 was significantly increased (p < 0.05) only in group A. In both group A and group B fibrinogen (p < 0.01 and p < 0.005, respectively), factor VII (p < 0.01 and p < 0.05, respectively), plasma C-reactive protein (p < 0.005 and p < 0.05, respectively) and oxidized LDL antibody (p < 0.05) were significantly decreased, while tissue-type plasminogen activator (p < 0.005), plasminogen activator inhibitor (p < 0.005) and total plasma antioxidant capacity (p < 0.005) were significantly increased.
Conclusions. Our results show a positive effect of these Sicilian red wines on many risk factors, suggesting a moderate consumption of red wine in the adult population as a component of the
Mediterranean diet

One-year atorvastatin treatment in hypercholesterolemic patients with or without carotid artery disease
Aim. Statins are the drugs of choice in heterozygous familial hypercholesterolemia (FH), which has a high risk of premature cardiovascular events including myocardial infarction, stroke, and surgical revascularization. Methods. A 1-year open-label study was conducted to test the efficacy and tolerability of Atorvastatin titrated to the target, in proven FH patients and to evaluate certain inflammatory parameters. One hundred and two FH patients (44 men and 58 women; mean age 58.7±3.6 years) were included in the study. After evaluation using the B-mode duplex scanning system of extracranial carotid arteries, the patients were divided into groups: Group 1 (15 men, 25 women) with carotid plaques or intima-media thickness (IMT) greater than 0.95 mm and Group 2 (30 men, 32 women) without carotid plaques or IMT less than 0.95 mm. After a 6-week hypolipemic diet phase all the patients were treated with atorvastatin titrated to achieve a low density lipoprotein (LDL-C) <100 mg/dL. Patients with carotid lesions were also submitted to an oral fixed dose of aspirin 100 mg/day. Results. In patients without and with carotid lesions, atorvastatin treatment (mean dosage: 23.5 mg/day) reduced triglycerides by 8.7% (P<0.005) and 10.6% (P<0.005), total cholesterol by 41.5% (P<0.005) and 42.6% (P<0.005), LDL-C by 55.8% (P<0.005) and 57.3% (P<0.005) and apolipoprotein B by 38.3% (P<0.005) and 37.2% (P<0.005) respectively, and increased the mean levels of high density lipoprotein cholesterol (HDL-C) by 8.7% (P<0.005) and 11% (P<0.005), and apolipoprotein A-I by 3.2% (P<0.05) and 3.3%, respectively. In both groups of patients the mean decrease (52 weeks) of fibrinogen was 19.8% (P<0.005) and 10.4% (P<0.005), respectively and of high sensitivity C-reactive protein (hs-CRP), 36.2% (P<0.005) and 38.2% (P<0.005), respectively. No variation of the parameters of safety and clinical tolerability of the drugs administered was observed. No variation in hematocrit in the patients taking ASA treatment was observed. Conclusion. In FH patients, 1-year atorvastatin treatment titrated to the target (LDL-C <100 mg/dL) was well tolerated and improved serum lipid levels and inflammatory parameters
Impact of atorvastatin plus n-3 PUFA on metabolic, inflammatory and coagulative parameters in metabolic syndrome without and with type 2 diabetes mellitus
Efficacy and safety of long-term ezetimibe/simvastatin treatment in patients with familial hypercholesterolemia
Aim. Patients with heterozygous familial hypercholesterolemia (FH) have an increased risk of premature myocardial infarction, stroke, and surgical revascularization, and an increased rate of progression of carotid intima-media thickness (IMT). The most commonly used drugs for cholesterol lowering, statins, have a limited action in these patients. Ezetimibe, a novel compound, selectively inhibits cholesterol uptake and when associated with statins has an additional low-density lipoprotein cholesterol (LDL-C) reducing effect. The aim of this study is to evaluate the effects of long-term combined Ezetimibe/Simvastatin (EZE/SIMVA) therapy (30 months) on the lipidic pattern, inflammatory markers, and carotid IMT in patients with FH subdivided into two groups: one with a history of acute myocardial infarction (IMA) and the other with carotid atherosclerotic plaques but no history of cardiovascular events. Methods. All patients enrolled in this study (group A: patients with a history of IMA; group B, patients with carotid lesions but no history of cardiovascular events) were submitted to a 6-week period of isocaloric diet and to a 4-week lipid-lowering wash-out period before study entry. After the wash-out period at baseline (time 0) and then every two months total cholesterol, triglycerides, highdensity lipoprotein cholesterol (HDL-C), and apolipoprotein B and A1 were determined. LDL-C levels were calculated. Fibrinogen and hs-CRP at baseline and at 6, 18, and 30 months were determined. All patients were submitted to an ultrasonographic evaluation of the carotid intimamedia thickness at baseline, 18 and 30 months. The scheduled duration time of the study was 30 months. At the beginning of the study all patients were assigned to receive the combined EZE/SIMVA treatment 10/20 mg per day. After two months, patients who had not reached the respective LDL-C targets proposed by NCEP ATPIII (<70 mg/dL for patients with a history of IMA and <100 mg/dL for patients with carotid lesions) were assigned to receive EZE/SIMVA 10/40 mg per day and, after four months, patients who had not reached the respective LDL-C targets were assigned to receive EZE/SIMVA 10/80 mg per day. Results. At the end-point, significant reductions (P<0.001) of about 70% in LDL-C, of 57% in total cholesterol (TC), of 46% in Apo-B, and of 46% in hs-C-reactive protein (hs-CRP) were observed in both groups compared to baseline. Also, triglyceride and fibrinogen levels were significantly (P<0.01) reduced, respectively by 26% and 15% compared to baseline. The EZE/SIMVA association resulted in significant increases in HDL-C (P<0.01) of 11% and in Apo-A1 (P<0.05) by 9% and in significant (P<0.001) reductions of the mean of the carotid IMT in both groups. The EZE/SIMVA treatment was generally well-tolerated, with a safety profile on laboratory parameters. During the 30-month scheduled period of the study, no patient in either group presented any further cardiovascular events. Conclusion. In patients with FH, combined EZE/SIMVA treatment resulted in a significant LDL-C lowering, achieving the goals proposed by NCEP ATP HI, in a significant improvement of all the lipidic and inflammatory patterns, and above all in a progressive decrease of the carotid IMT. Although the results of ongoing randomized controlled trials are required before making any definitive conclusions, our results support the hypothesis of stabilizing effect of EZE/SIMVA on the atherosclerotic disease both in primary and in secondary prevention
Immunoinflammatory Activation during the Acute Phase of Lacunar and Non-Lacunar Ischemic Stroke: Association with Time of Onset and Diabetic State
Several studies have stressed the involvement of inflammation in the pathophysiology of acute brain ischemia, but the role of immunoinflammatory activation in diabetic stroke patients has not yet been fully evaluated. The aim of our study was to evaluate immunoinflammatory activation of acute phase of stroke in relation to time of symptoms onset, diabetic state and diagnostic subtype. We enrolled 60 patients (32 diabetics; 28 non- diabetics) with acute ischemic stroke and 123 subjects without acute ischemic stroke, and measured levels of IL-1β, TNF-α, IL-6, IL-10, E-selectin, P-selectin, sICAM-1, sVCAM-1, VWF, 24–72 h and 7–10 days after stroke onset; TPA, PAI-1 plasma levels at 24–72h. Our stroke patients exhibited significantly higher plasma levels of cytokines, selectins, adhesion molecules and PAI-1, and diabetic stroke patients exhibited higher plasma levels of PAI-1 in comparison with non-diabetic ones. Lacunar strokes in comparison with those non-lacunar exhibited significantly lower levels of TNF-α and IL1-β, P-selectin and ICAM-1. Moreover, diabetic patients with lacunar strokes exhibited a minor grade of immunoinflammatory activation of the acute phase at 24–72h and 7–10 days after stroke onset. The minor grade of immunoinflammatory activation of patients with lacunar strokes, particularly diabetic ones, could be related to the minor extension of the infarct size, owing to the typical microvascular disease of diabetic subjects which could also explain the reported better outcome of this subtype of ischemic stroke
Long-term anti-tumour necrosis factor therapy reverses the progression of carotid intima-media thickness in female patients with active rheumatoid arthritis
The objective of the study is to evaluate the effect of TNF inhibition on carotid thickness over a 2-year period. 144 women with RA diagnosed according to ACR criteria, without clinical evidence of cardiac and/or vascular disease were enrolled and compared with 78 matched controls. All patients received methotrexate (15–20 mg weekly) for 3 months. Responders (n = 79) continued to be treated with methotrexate, non-responders (n = 40) moved to methotrexate plus a TNF alpha antagonist. Echosonographic studies of carotids were obtained before and after 2-year follow-up. A significant decrease of ca-IMT was observed in anti-TNF-treated patients (P < 0.001); on the other hand, no significant variation of ca-IMT was observed after 2 years in MTX-treated patients. Our study indicates that anti-TNF blocking agents, but not methotrexate, are capable of reducing IMT of carotid arteries in female RA patients in a 2-year follow-up
