Chylomicron Metabolism

Obese insulin resistant individuals often present with a dyslipidemic phenotype characterised by hypertriglyceridemia, low HDL cholesterol levels, essentially normal total- and LDL-cholesterol, but a propensity for smaller, denser LDL particles. We have reported that concentrations of chylomicrons are two to three folds greater than in age-matched lean controls. We have recently observed that in lean free-living subjects the flux of chylomicrons over a 12h period was just 25% greater in these subjects than basal chylomicron production. Constitutive secretion of chylomicrons appears to be of greater relevance to arterial exposure than postprandial fluctuations. Insulin critically regulates the metabolism of very low density lipoprotein (VLDL) and hence it would be expected that the hormone is also involved in the regulation of chylomicron metabolism. Impaired insulin action may therefore be responsible for the associated hyperchylomicronaemia. In this review we examine the hypothesis that insulin chronically modulates chylomicron metabolism and present evidence suggesting that hyperchylomicronaemia primarily results from impaired chylomicron production.

Disease Risk Factor

A population-based study was conducted in 1994 in Isfahan to define the prevalence of various types of hyperlipidaemia and the mean concentrations of serum total cholesterol, triglycerides, low-density lipoprotein cholesterol and high-density lipoprotein [HDL]cholesterol. In all, 2200 people were randomly chosen and classified into five age groups [20-70 years]. The data were obtained by questionnaires and anthropometric measurements and serum lipids and fasting blood sugar were measured. The prevalence of hyperlipidaemia was higher in women than men. Multiple linear regression showed only HDL cholesterol and triglycerides to be associated with body mass index. The most prevalent lipid abnormality was HDL cholesterol. Diet modification and physical activity should be encouraged to reduce hyperlipidaemia

Cluster Of Differentiation

Many studies have assessed the implication of cluster of differentiation 14 (CD14) molecules and its single nucleotide polymorphism rs2569190A>G with different complex diseases, such as diabetes and cardiovascular diseases (CVDs). In this study, we investigated the association of rs2569190A>G in CD14 with cardiovascular disease risk factors (hypercholesterolemia and hypertension) in 460 individuals from the general Lebanese population (Middle Eastern multiethnic population). Using a multiple logistic regression model adjusted for six covariates (under additive and recessive assumptions), we found that the G allele of rs2569190 in CD14 was associated with increased levels of total cholesterol (OR = 3.10, p = 0.009), low-density lipoprotein cholesterol (OR = 3.87, p = 0.003), and decreased levels of high-density lipoprotein cholesterol (OR = 0.38, p = 0.001). In contrast, no significant relationship was found with hypertension. Thus, we concluded that rs2569190G in CD14 is associated with a higher risk of developing hypercholesterolemia.

Key Factor

We tested the hypothesis that reductions in vascular endothelial function (endothelium-dependent dilation, EDD) with age are related to increases in sympathetic activity. Among 314 healthy men and women, age was inversely related to brachial artery flow-mediated dilation (FMD) ( r = −0.30, P < 0.001), a measure of EDD, and positively related to plasma norepinephrine concentrations (PNE), a marker of sympathetic activity ( r = 0.49, P < 0.001). Brachial FMD was inversely related to PNE in all subjects ( r = −0.25, P < 0.001) and in men ( n = 187, r = −0.17, P = 0.02) and women ( n = 127, r = −0.37, P < 0.001) separately. After controlling for PNE (multiple regression analysis), brachial FMD remained significantly related to age in all subjects ( r = −0.20, P < 0.001) and in men ( r = −0.23, P < 0.01), but not women ( r = −0.16, P = 0.06). Consistent with this, brachial FMD remained significantly related to PNE when controlling for age ( r = −0.24, P < 0.01) and menopause status ( r = −0.24, P < 0.01) in women. Indeed, PNE was the strongest independent correlate of brachial FMD in women after controlling for conventional cardiovascular disease risk factors ( r = −0.22, P = 0.01). This relation persisted in a subset of women ( n = 113) after further accounting for the effects of plasma oxidized low-density lipoprotein ( P < 0.05), a circulating marker of oxidative stress. Endothelium-independent dilation was not related to age in either men or women ( P > 0.05). These results provide the first evidence that EDD is inversely related to sympathetic activity, as assessed by PNE, among healthy adults varying in age. In particular, our findings suggest that sympathetic nervous system activity may be a key factor involved in the modulation of vascular endothelial function with aging in women.

To assess the risk to Tunisian children of cardiovascular diseases [CVD], we undertook an epidemiological survey of 1569 urban schoolchildren from Sousse. Prevalence rates for the following CVD risk factors were determined: hypertension, hypercholesterolaemia and other lipid disorders, obesity and tobacco consumption. Hypertension and hypertriglyceridaemia showed no statistically significant difference by sex. Hypercholesterolaemia, high levels of low-density lipoprotein cholesterol and obesity were all significantly higher for girls than boys. Smoking was significantly higher among boys. The relatively low CVD risk factor profile of Tunisian schoolchildren should be encouraged in adulthood and a school heart health programme should be established.

Prevention Methods

Background and Aim: Elevated low-density lipoprotein cholesterol and/or lipoprotein(a) are established risk factors for cardiovascular disease (CVD). Management of hypercholesterolemia consists of drug therapies, including statins and proprotein convertase subtilisin/kexin type 9 inhibitors. In patients with familial hypercholesterolemia (FH), lipoprotein apheresis (LA) is utilized to control lipid levels. However, LA is not currently a standard therapy for non-FH. This review summarizes the literature regarding LA therapy in CVD prevention. Methods: PubMed/MEDLINE databases were searched using the keywords “LA” and “CVD”. Citations were individually reviewed for relevance. Results: The efficacy of LA was clearly demonstrated, largely based on evidence from observational studies. In patients who are unresponsive to traditional lipid-lowering medications, LA effectively reduced serum lipoprotein levels and adverse cardiovascular events. Conclusion: It was concluded that LA is a safe and effective technique that could be considered in the management of hypercholesterolemia and future risk. Randomized control trials would further support a role for LA as a therapeutic option.

Background: Familial hypercholesterolaemia (FH) is a genetically determined lipid disorder, affecting 1 per 200-500 individuals in the general population. It is significantly and independently associated with an increased risk of Cardiovascular Disease (CVD), although it remains still an underrecognized and undertreated disease. Lipoprotein (a) [Lp(a)] is a low-density-lipoprotein (LDL)-like molecule, containing an additional protein, apolipoprotein (a). Objective: This review aims to present and discuss available data on the role of Lp(a) in patients with FH, in terms of its potential augmentation of CVD risk. Methods: A comprehensive search of the literature was performed to identify studies evaluating the CV effects of Lp(a) in patients with FH. Results: Lp(a) has been recognised as an independent risk factor for CVD, mainly coronary artery disease (CAD). Most, but not all, studies show increased Lp(a) concentrations in adults and children with FH. There is also evidence of an independent association between Lp(a) and CVD (mainly CAD) risk in these patients. Conclusion: Some therapeutic modalities, such as niacin, oestrogens, tibolone and proprotein convertase subtilisin/ kexin type 9 (PCSK9) inhibitors may effectively reduce Lp(a) concentrations by 25-30%, although their clinical benefit of this effect remains to be established.

Meta Analyses

The elimination of specific dietary cholesterol target recommendations in recent guidelines has raised questions about its role with respect to cardiovascular disease. This advisory was developed after a review of human studies on the relationship of dietary cholesterol with blood lipids, lipoproteins, and cardiovascular disease risk to address questions about the relevance of dietary cholesterol guidance for heart health. Evidence from observational studies conducted in several countries generally does not indicate a significant association with cardiovascular disease risk. Although meta-analyses of intervention studies differ in their findings, most associate intakes of cholesterol that exceed current average levels with elevated total or low-density lipoprotein cholesterol concentrations. Dietary guidance should focus on healthy dietary patterns (eg, Mediterranean-style and DASH [Dietary Approaches to Stop Hypertension]–style diets) that are inherently relatively low in cholesterol with typical levels similar to the current US intake. These patterns emphasize fruits, vegetables, whole grains, low-fat or fat-free dairy products, lean protein sources, nuts, seeds, and liquid vegetable oils. A recommendation that gives a specific dietary cholesterol target within the context of food-based advice is challenging for clinicians and consumers to implement; hence, guidance focused on dietary patterns is more likely to improve diet quality and to promote cardiovascular health.
