Association between Lp(a) and small dense LDL in menopausal women without metabolic syndrome.

Lipoprotein (a) (Lp [a]) is associated with premature atherosclerosis in menopausal women without metabolic syndrome (MS). MS is the main confounder in the relationship between Lp(a) and atherosclerosis in menopausal women. We have evaluated the relationship between Lp(a) and small dense-low density lipoprotein (sd-LDL) in 228 menopausal women participating to Progetto Atena.

Causative mutations and premature cardiovascular disease in patients with heterozygous familial hypercholesterolaemia.

Background Familial hypercholesterolemia is a common autosomal dominant disease, caused by mutations leading to elevated low-density lipoprotein (LDL) cholesterol and, if untreated, to premature cardiovascular disease. Methods Patients (young adults with a family history of hypercholesterolaemia or premature cardiovascular disease) with LDL cholesterol concentration ≥4.9 mmol/l, after excluding Familial Combined Hyperlipidaemia, were evaluated for causative mutations, Dutch Lipid Clinic Network score calculation and non-invasive ultrasound examination of carotid arteries.

Cerebrotendinous xanthomatosis, a metabolic disease with different neurological signs: two case reports.

Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive inborn error of bile acids synthesis and lipid accumulation caused by a deficiency of the mitochondrial cytochrome P450 sterol 27-hydroxylase enzyme encoded by CYP27A1. Pathogenic variants in CYP27A1 cause elevated cholestanol levels in the body, which leads to a variable clinical presentation that often includes cataracts, intellectual disability, neurological features, tendon xanthomas, and chronic diarrhea. Herein we describe the cases of two unrelated adult CTX patients.

Effects of Armolipid Plus on small dense LDL particles in a sample of patients affected by familial combined hyperlipidemia.

Aim: The aim of this study was to test small dense LDL changes with Armolipid Plus treatment in patients with familial combined hyperlipidemia (FCHL).

Methods: After 4 weeks, 30 patients with FCHL were included in an 8-week, randomized, double-blind study and were taking, in addition to the standard diet, either placebo or Armolipid Plus.

Results: The placebo group showed no statistically significant differences in the studied parameters; instead, in the Armolipid Plus group, statistically significant reduction differences were detected in BMI (p = 0.

Association between Lp (a) and atherosclerosis in menopausal women without metabolic syndrome.

Aim: The association between Lipoprotein (a) (Lp [a]) and common carotid intima media thickness (IMT) has been evaluated in 222 menopausal women.

Material & Methods: Lp (a) and IMT were measured, carotid ultrasound examination (B-Mode imaging) was performed and mean max IMT was calculated.

Results: Lp (a) was significantly lower in women with metabolic syndrome (MS).

Association of USF1 and APOA5 polymorphisms with familial combined hyperlipidemia in an Italian population.

Background: Familial combined hyperlipidemia (FCH) is a polygenic and multifactorial disease characterized by a variable phenotype showing increased levels of triglycerides and/or cholesterol. The aim of this study was to identify single nucleotides (SNPs) in lipid-related genes associated with FCH.

Methods And Results: Twenty SNPs in lipid-related genes were studied in 142 control subjects and 165 FCH patients after excluding patients with mutations in the LDLR gene and patients with the E2/E2 genotype of APOE.

Effects of baked products enriched with n-3 fatty acids, folates, β-glucans, and tocopherol in patients with mild mixed hyperlipidemia.

Objective: To assess whether a diet containing foods enriched with β-glucans (3.6 g/d), folic acid (1600 μg/d), long-chain (800 mg/d) and short-chain (400 mg/d) n-3 fatty acids, and tocopherols (120 mg/d) is able to modulate positively the cardiovascular risk profile in people at slightly increased cardiovascular risk.

Methods: Sixteen subjects with mild plasma lipid abnormalities were studied according to a randomized crossover design.

An improved method on stimulated T-lymphocytes to functionally characterize novel and known LDLR mutations.

The main causes of familial hypercholesterolemia (FH) are mutations in LDL receptor (LDLR) gene. Functional studies are necessary to demonstrate the LDLR function impairment caused by mutations and would be useful as a diagnostic tool if they allow discrimination between FH patients and controls. In order to identify the best method to detect LDLR activity, we compared continuous Epstein-Barr virus (EBV)-transformed B-lymphocytes and mitogen stimulated T-lymphocytes.

Identification and functional characterization of LDLR mutations in familial hypercholesterolemia patients from Southern Italy.

Objective: Autosomal dominant hypercholesterolemias are due to defects in the LDL receptor (LDLR) gene, in the apolipoprotein B-100 gene or in the proprotein convertase subtilisin/kexin type 9 gene. The aim of this study was to identify and functionally characterize mutations in the LDLR gene that account for most cases of familial hypercholesterolemia (FH).

Methods: We enrolled 56 unrelated patients from Southern Italy with a clinical diagnosis of FH.

Efficacy and safety of rosuvastatin in the management of dyslipidemia.

Rosuvastatin is a synthetic statin that represents an advance in the pharmacologic and clinical properties of statins. Relative to other statins, rosuvastatin possesses a greater number of binding interactions with HMG-CoA reductase and has a high affinity for the active site of the enzyme. As with other statins, serious adverse effects with rosuvastatin therapy are uncommon and primarily involve effects on the liver and skeletal muscle.

Small dense low-density lipoprotein in familial combined hyperlipidemia: Independent of metabolic syndrome and related to history of cardiovascular events.

Introduction: It is unclear whether small dense low-density lipoprotein (sdLDL) are associated with familial combined hyperlipidemia (FCHL), independently of the metabolic syndrome (MS). It is also unclear whether sdLDL are related to history of cardiovascular (CVD) events in FCHL patients, independently of MS.

Patients And Methods: Serum levels of sdLDL, expressed as percentage of total LDL cholesterol (LDL score), were determined in 137 probands with FCHL and in 133 normolipidemic, normotensive, normoglycemic healthy subjects.

Tumor necrosis factor-alpha is a marker of familial combined hyperlipidemia, independently of metabolic syndrome.

It is unclear whether an association between familial combined hyperlipidemia (FCHL) and inflammatory markers exists, independently of age, sex, body weight, insulin resistance, and metabolic syndrome. Serum concentrations of soluble vascular cell adhesion molecule-1 (sVCAM-1), monocyte chemoattractant protein 1, interleukin 6, tumor necrosis factor-alpha (TNF-alpha), and high-sensitive C-reactive protein were determined in 135 probands with FCHL and in 146 normolipidemic, normotensive, normoglycemic healthy subjects. Insulin resistance was evaluated using homeostasis model assessment (HOMA).

Small dense LDL particles and metabolic syndrome in a sample of middle-aged women. Findings from Progetto Atena.

Metabolic Syndrome (MS) is highly prevalent in the general population. Recently, small dense LDL (sd-LDL) particles have been considered a risk marker in MS diagnosis. We analyzed cross-sectionally the association between sd-LDL and MS in a population-based sample of 210 middle-aged southern Italian women; among them 86 participants had MS (prevalence 40.
