Objective: To determine the presence of early carotid atherosclerosis and associated risk factors in patients with juvenile-onset systemic lupus erythematosus (SLE).

Methods: The carotid intima-media wall thickness (IMT) was measured by B-mode ultrasound in patients with SLE onset before the age of 16 years and in sex- and age-matched healthy control subjects. Risk factors for atherosclerosis were determined at the time of the ultrasound scan and included traditional cardiovascular and SLE-related risk factors.

Low density lipoprotein (LDL) oxidation plays a crucial role in the development and progression of atherosclerosis and is enhanced in patients with essential hypertension. This finding has stimulated a search for antihypertensive drugs with high intrinsic antioxidant properties. We investigated the antihypertensive and antioxidant effects of carvedilol, a new vasodilating beta-adrenoceptor blocking agent in a group of patients with mild to moderate essential hypertension after 4-month treatment.

Background: Topical application of inhibitors of HMGCoA reductase, the rate-limiting enzyme of cholesterol synthesis, has been shown to induce impairment of barrier function.

Objective: Assessing whether oral administration of statins used for reducing blood levels of cholesterol induces functional changes in stratum corneum barrier.

Materials And Methods: 69 subjects of both sexes under-going treatment for hypercholesterolemia (mean age 48 +/- 11 years) entered the study; 43 had been treated with simvastatin and 11 with pravastatin for 6 months; 15 only on dietary regimen served as controls.

Objectives: The oxidation of low-density lipoproteins has been recently proposed as one of the critical factors in promoting atherogenesis. This process results from the balance between the prooxidant stimuli and the endogenous antioxidants present in LDL and strictly depends on the concentration of oxidizable substrates, namely unsaturated fatty acids.

Methods: Twelve male hypertriglyceridaemic patients were investigated before and after oral supplementation with omega-3 polyunsaturated fatty acids (PUFA) and compared with eighteen untreated healthy matched control subjects.

Objective: To evaluate the efficacy and safety of simvastatin administered to a group of heart transplant patients receiving triple-drug immunosuppressive therapy. We also assessed the potential pharmacokinetic interaction between simvastatin and cyclosporine by comparing mean plasma concentrations of simvastatin beta-hydroxy acid, the major metabolite of the drug, in a group of heart transplant patients treated with cyclosporine and in a control group of patients who had not received heart transplants. Both groups received long-term (> 6 wk) simvastatin therapy.

Objectives: Evidence has been obtained indicating that oxidation of low-density lipoproteins (LDL) plays a relevant role in the pathogenesis of atherosclerosis and it has been proposed that, due to the antigenic properties of oxidized LDL, the anti-oxLDL antibody titre could represent a useful index of in vivo LDL oxidation.

Methods: Sixty-nine control subjects and 64 patients scheduled for selective coronary revascularization were investigated before surgery.

Results: The coronary disease patients had a higher level of total plasma cholesterol, LDL cholesterol and triglycerides, and a lower level of HDL cholesterol.

Metabolic disturbances such as hyperinsulinaemia, dislipoproteinaemia and glucose intolerance are often associated with essential hypertension and markedly affect cardiovascular morbidity in hypertensive patients. In order to shed some light on the prognostic significance of white coat hypertension (raised clinic and normal ambulatory blood pressure), we compared the metabolic profile in a group of white coat and sustained previously untreated hypertensives. We studied 84 newly detected hypertensive patients (49 men, 35 women, 47 +/- 8 years, range 28-59 years).

Since oxidized low-density lipoprotein (LDL) is more atherogenic than native LDL, LDL oxidation was investigated in uremic patients who often develop accelerated atherogenesis. Three groups of uremic patients were studied (10 on predialysis conservative therapy, 11 on repetitive hemodialysis, 13 on peritoneal dialysis) and compared with seventy matched controls. LDL oxidation was evaluated in all patients as: (i) the susceptibility to in vitro oxidation (by measuring the resistance to Cu(++)-induced formation of conjugated dienes), (ii) vitamin E concentration in LDL, and (iii) presence of plasma anti-oxidized LDL antibodies, expressed as the ratio anti-oxLDL/anti-nativeLDL antibodies.

Due to the potential atherogenic effects of oxidized low-density lipoproteins (LDLs), LDL oxidation was studied in a group of uremic patients on chronic peritoneal dialysis. The results were compared with those obtained in a group of 70 controls, 10 uremic patients on predialytic conservative therapy, and 11 patients on repetitive hemodialysis. LDL oxidation was evaluated in all subjects as the susceptibility to in vitro oxidation (monitoring the resistance to Cu(2+)-induced formation of conjugated dienes, lag-phase minutes) and the presence of plasma antioxidized LDL antibodies, expressed as the ratio anti-ox-LDL/antinative LDL antibodies.

Using digitized M-mode echocardiography, the left ventricular (LV) response to acute increase in blood pressure after regression of myocardial hypertrophy due to an effective antihypertensive treatment was evaluated. Fifteen hypertensive patients with basal LV hypertrophy (LV mass greater than 230 g, and normal LV diastolic diameter) and normal LV mass after 3 to 4 months of treatment with angiotensin-converting enzyme inhibitors were selected for study. Subjects performed a cold pressor test before and after therapy.
