Lecithin-cholesterol-acyltransferase deficiency: autosomal recessive transmission in a large kindred.

2008

Thirty-four members of a single Sardinian kindred with lecithin-cholesterol-acyltransferase deficiency have been studied. The kindred spans four generations and the parents of the two affected siblings are blood relatives. Segregation of the acyltransferase deficiency gene in the family clearly demonstrated an autosomal recessive mode of inheritance. Thirteen family members, including all obligate heterozygotes, had roughly half-normal acyltransferase activities (mean +/- S.D. = 0.39 +/- 0.06 mU/ml) when compared to 17 intrafamilial controls and spouses (mean +/- S.D. = 0.72 +/- 0.09 mU/ml) and 40 blood donors from Marburg/Lahn (mean +/- S.D. =0.76 +/- 0.1 mU/ml). Characterization of the he…

The lipid-lowering effects of lomitapide are unaffected by adjunctive apheresis in patients with homozygous familial hypercholesterolaemia – A post-h…

2015

AbstractObjectiveLomitapide (a microsomal triglyceride transfer protein inhibitor) is an adjunctive treatment for homozygous familial hypercholesterolaemia (HoFH), a rare genetic condition characterised by elevated low-density lipoprotein-cholesterol (LDL-C), and premature, severe, accelerated atherosclerosis. Standard of care for HoFH includes lipid-lowering drugs and lipoprotein apheresis. We conducted a post-hoc analysis using data from a Phase 3 study to assess whether concomitant apheresis affected the lipid-lowering efficacy of lomitapide.MethodsExisting lipid-lowering therapy, including apheresis, was to remain stable from Week −6 to Week 26. Lomitapide dose was escalated on the basi…

Prevalence Of familial hypercholeSTerolaemia (FH) in Italian Patients with coronary artERy disease: The POSTER study

2020

Background and aims: Familial hypercholesterolaemia (FH) is a powerful risk factor for cardiovascular (CV) events. High levels of low-density lipoprotein cholesterol (LDL-C) since birth are linked to the early onset of atherosclerotic disease. A genetic mutation determining FH is present in about one subject out of 250; FH should be more represented among subjects with a documented diagnosis of coronary artery disease (CAD). The POSTER Study evaluated the prevalence of FH in Italian patients with a recent CAD event. Methods: Eighty-two cardiology centres enrolled patients with a documented CAD event; CV risk profile, drug therapy and biochemical parameters were collected. Dutch Lipid Clinic…

An Update on the Role of the Quality of LDL in Cardiovascular Risk:The Contribution of the Universities of Palermo and Zurich

2007

Low density lipoproteins (LDL) size seems to be an important predictor of cardiovascular events and progression of coronary artery disease and the predominance of small dense LDL have been accepted as an emerging cardiovascular risk factor by the National Cholesterol Education Program Adult Treatment Panel III. We recently showed increased LDL size or higher levels of small, dense LDL in different categories of patients at higher cardiovascular risk, such as those with coronary (including acute myocardial infarction) and non-coronary (including carotid disease, abdominal aortic aneurysm and peripheral arterial disease) forms of atherosclerosis or metabolic diseases (including type-II diabet…

Rapid degradation of ABCA1 protein following cAMP withdrawal and treatment with PKA inhibitor suggests ABCA1 is a short-lived protein primarily regul…

2020

Objectives: ATP-binding cassette transporter A1 (ABCA1) is a key player in the reverse cholesterol transport (RCT) and HDL biogenesis. Since RCT is compromised as a result of ABCA1 dysfunction in diabetic state, the objective of this study was to investigate the regulation of ABCA1 in a stably transfected 293 cells expressing ABCA1 under the control of cAMP response element. Methods: To delineate transcriptional and posttranscriptional regulation of ABCA1, 293 cells were stably transfected with the full length ABCA1 cDNA under the control of CMV promoter harboring cAMP response element. cAMP-mediated regulation of ABCA1 and cholesterol efflux were studied in the presence of 8-Br-cAMP and af…

Prevalence and determinants of diabetes mellitus in a representative sample of Italian adults

2022

PREVALENCE AND DETERMINANTS OF DIABETES MELLITUS IN A REPRESENTATIVE SAMPLE OF ITALIAN ADULTSBackground: Diabetes mellitus is a dramatic epidemic worldwide. This study providea an updated estimate of itsprevalence and determinants among Italian adults.Methods: Data were derived from a face-to-face survey conducted in 2013 on 2901 individuals (1391 men, 1510 women) aged ≥18 years, representative of the general adult Italian population. Odds ratios (OR) for diabetes versus non diabetes in relation to selected risk factors were derived using multiple logistic regression models.Results: Overall, 135 out of 2901 adults (4.7%) reported a diagnosis of diabetes, with similar prevalence in men (4.8%…

Pro-oxidant effects of 7-hydroperoxycholest-5-en-3β-ol on the copper-initiated oxidation of low density lipoprotein

1995

AbstractIn low density lipoproteins (LDL) supplemented with aged cholesterol and oxidized in the presence of Cu2+, an increase of the lipid oxidation parameters was observed compared with pure cholesterol-enriched LDL. A compound, identified as 7-hydroperoxycholesterol (7HPC), isolated from aged cholesterol and added to LDL, reproduced the above effects. The results indicate that the pro-oxidant effect of 7HPC is dependent on the hydroperoxy group since the corresponding alcohol derivative, 7α-hydroxycholesterol, had no such effect. These data suggest that among the LDL-associated lipid peroxides, cholesterol peroxides may have important implications in the susceptibility of this lipoprotei…

Emergence of ovulatory cycles with aging in women with polycystic ovary syndrome (PCOS) alters the trajectory of cardiovascular and metabolic risk fa…

2013

Abstract STUDY QUESTION: What alters cardiovascular and metabolic risk factors with aging in women with polycystic ovary syndrome (PCOS)? SUMMARY ANSWER: Lipid parameters, mainly low-density lipoprotein (LDL) cholesterol, increase with aging, but not in women who attain ovulatory cycles. WHAT IS KNOWN ALREADY: Cardiovascular and metabolic parameters tend to increase with aging, but this has not been shown in a prospective longitudinal study in women with PCOS. Correlates of these changes have not been identified. STUDY DESIGN: A prospective cohort of 118 hyperandrogenic women with PCOS who were followed from the age of 20-25 years at 5 year intervals for 20 years. PARTICIPANTS/MATERIALS, SE…

Nutraceuticals and functional foods for the control of plasma cholesterol levels. An intersociety position paper

2018

Current evidence shows that cholesterol management either reduces the likelihood of cardiovascular disease (CVD) or slows down its progression. Hence, it is important that all health professionals make appropriate use of all the available intervention strategies to control risk factors: from dietary improvement and positive lifestyle changes to the use of functional foods, food supplements, and drugs. This review examines the effect of the most frequently occurring cholesterol-lowering substances in functional foods or in supplements across Europe, namely plant sterols and stanols, monacolin K found in red yeast rice, berberine and beta-glucans. We conclude that currently available suppleme…
