Update on the detection and treatment of atherogenic low-density lipoproteins

Sniderman, Allana; Kwiterovich, Peter O.b

Abstract

Purpose of review: To explain why epidemiological studies have reached such diverse views as to whether apolipoprotein B (apoB) and/or low-density lipoprotein particle number (LDL-P) are more accurate markers of the risk of cardiovascular disease than LDL-C or non-high-density lipoprotein cholesterol (HDL-C) and to review the treatment options to lower LDL.
Recent findings: The Emerging Risk Factor Collaboration, a large prospective participant level analysis, a meta-analysis of statin clinical trials, and the Heart Protection Study have each reported that apoB does not add significantly to the cholesterol markers as indices of cardiovascular risk. By contrast, a meta-analysis of published prospective studies demonstrated that non-HDL-C was superior to LDL-C, and apoB was superior to non-HDL-C. As well, three studies using discordance analysis each demonstrated that apoB and LDL-P were superior to the cholesterol markers. Two approaches to resolve these differences are brought to bear in this article: first, which results are credible and second, how does taking the known differences in LDL composition into account, help resolve them. The best identification of individuals at risk of coronary artery disease or with coronary artery disease allows the most efficacious treatment of elevated LDL-P and will permit a more extensive use of some of the more novel LDL-lowering agents.
Summary: Much of the controversy vanishes once the physiologically driven differences in the composition of the apoB lipoprotein particles are taken into account, illustrating that epidemiology, not directed by physiology, is like shooting without aiming.

Abstract

Purpose of review: Dyslipidemia is a powerful risk factor for cardiovascular disease (CVD). Dietary fatty acid composition regulates lipids and lipoprotein metabolism and may confer CVD benefit. This review updates understanding of the effect of dietary fatty acids on lipoprotein metabolism in humans.
Recent findings: High dietary fish-derived n-3 polyunsaturated fatty acid (PUFA) consumption diminished hepatic triglyceride-rich lipoprotein (TRL) secretion and enhanced TRL to LDL conversion. n-3 PUFA also decreased TRL-apoB-48 concentration by decreasing TRL-apoB-48 secretion. High n-6 PUFA intake decreased liver fat, and plasma proprotein convertase subtilisin/kexin type 9, triglycerides, total-cholesterol and LDL-cholesterol concentrations. Intake of saturated fatty acids with increased palmitic acid at the sn-2 position was associated with decreased postprandial lipemia, which might be due to decreased triglyceride absorption. Replacing carbohydrate with monounsaturated fatty acids increased TRL catabolism. Ruminant trans-fatty acid decreased HDL cholesterol, but the mechanisms are unknown. A new role for APOE genotype in regulating lipid responses was also described.
Summary: The major advances in understanding the effect of dietary fatty acids on lipoprotein metabolism have focused on n-3 PUFA. This knowledge provides insights into the importance of regulating lipoprotein metabolism as a mode to improve plasma lipids and potential CVD risk. Further studies are required to better understand the cardiometabolic effects of other dietary fatty acids.

Abstract

Background: Added sugar consumption seems to trigger a hyperinflammatory state and may result in visceral adiposity, dyslipidemia, and insulin resistance. These conditions are risk factors for periodontal disease. However, the role of sugar intake in the cause of periodontal disease has not been adequately studied.
Objective: We evaluated the association between the frequency of added sugar consumption and periodontal disease in young adults by using NHANES III data.
Design: Data from 2437 young adults (aged 18–25 y) who participated in NHANES III (1988–1994) were analyzed. We estimated the frequency of added sugar consumption by using food-frequency questionnaire responses. We considered periodontal disease to be present in teeth with bleeding on probing and a probing depth ≥3 mm at one or more sites. We evaluated this outcome as a discrete variable in Poisson regression models and as a categorical variable in multinomial logistic regression models adjusted for sex, age, race-ethnicity, education, poverty-income ratio, tobacco exposure, previous diagnosis of diabetes, and body mass index.
Results: A high consumption of added sugars was associated with a greater prevalence of periodontal disease in middle [prevalence ratio (PR): 1.39; 95% CI: 1.02, 1.89] and upper (PR: 1.42; 95% CI: 1.08, 1.85) tertiles of consumption in the adjusted Poisson regression model. The upper tertile of added sugar intake was associated with periodontal disease in ≥2 teeth (PR: 1.73; 95% CI: 1.19, 2.52) but not with periodontal disease in only one tooth (PR: 0.85; 95% CI: 0.54, 1.34) in the adjusted multinomial logistic regression model.
Conclusion: A high frequency of consumption of added sugars is associated with periodontal disease, independent of traditional risk factors, suggesting that this consumption pattern may contribute to the systemic inflammation observed in periodontal disease and associated noncommunicable diseases.

Abstract

Purpose: Deregulation of STAT3 activation is a hallmark of many cancer cells, and the underlying mechanisms are subject to intense investigation. We examined the extent of PIAS3 expression in mesothelioma cells and human tumor samples and determined the functional effects of PIAS3 expression on STAT3 signaling.
Experimental design: We evaluated the expression of PIAS3 in mesothelioma tumors from patients and correlated the expression levels with the course of the disease. We also measured the effects of enhanced PIAS3 activity on STAT3 signaling, cellular growth, and viability in cultured mesothelioma cells.
Results: Gene expression databases revealed that mesotheliomas have the lowest levels of PIAS3 transcripts among solid tumors. PIAS3 expression in human mesothelioma tumors is significantly correlated with overall survival intervals (P = 0.058). The high expression of PIAS3 is predictive of a favorable prognosis and decreases the probability of death within one year after diagnosis by 44%. PIAS3 expression is functionally linked to STAT3 activation in mesothelioma cell lines. STAT3 downregulation with siRNA or enhanced expression of PIAS3 both inhibited mesothelioma cell growth and induced apoptosis. Mesothelioma cells are sensitive to curcumin and respond by the induction of PIAS3. Corroborative evidence has been obtained from STAT3 inhibition experiments. Exposure of the cells to a peptide derived from the PIAS3 protein that interferes with STAT3 function resulted in apoptosis induction and the inhibition of cell growth.
Conclusion: These results suggest that PIAS3 protein expression impacts survival in patients with mesothelioma and that PIAS3 activation could become a therapeutic strategy. Clin Cancer Res; 20(19); 1–9. ©2014 AACR.

Abstract

Inflammation is a key mediator in the development of malignant mesothelioma, which has a dismal prognosis and poor therapeutic strategies. Curcumin, a naturally occurring polyphenol in turmeric, has been shown to possess anticarcinogenic properties through its anti-inflammatory effects. Inflammasomes, a component of inflammation, control the activation of caspase-1 leading to pyroptosis and processing of proinflammatory cytokines, interleukin (IL)-1β and IL-18. In the present study, we investigate the role of curcumin in pyroptotic cell death of malignant mesothelioma cells. Using in vitro models with mouse and human malignant mesothelioma cells, curcumin is shown to induce pyroptosis through activation of caspase-1 and increased release of high-mobility group box 1 (HMGB1) without processing of IL-1β and IL-18. Absence of IL-1β processing in response to curcumin-mediated caspase-1 activation is attributed to blockade of pro-IL-1β priming through inhibition of the NF-κB pathway. Furthermore, curcumin's cytotoxicity in malignant mesothelioma cells is demonstrated to be dependent on pyroptosis as inhibition of caspase-1 resulted in protection against curcumin-induced cell death. We also demonstrate that curcumin-mediated caspase-1 activation is oxidant dependent by using N-acetyl-L-cysteine (NAC) to inhibit pyroptosis. PCR array analysis using the human inflammasome template revealed that curcumin significantly downregulated levels of inflammasome-related gene expression involved in inflammation, e.g., NF-κB, toll-like receptors (TLR), and IL-1β. Our data indicate that curcumin has a double effect on malignant mesothelioma cells through induction of pyroptosis while subsequently protecting against inflammation. Cancer Prev Res; 7(3); 330–40. ©2014 AACR.

Des décennies de conseils alimentaires qui s'effondrent

Butter: It has long been thought that consuming too much saturated fat, such as that found in butter, increases the risk of heart disease but a recent study found no significant link. 

Cheese: Once seen as a risk for heart disease, some experts now consider it is rich in fats that may be good for the body. One study found eating cheese might reduce the risk of diabetes. 

Low-fat yoghurts: The public health campaign against fat led to a huge range of lower fat products but many contained added sugar and are often not the healthiest option. 

Red wine: It contains the chemical resveratrol which has been considered to have long-term health benefits. However, a report published earlier this year found no evidence that it stops heart disease or prolongs life. 

Coffee: Once considered detrimental to heart health, it is now thought to have health benefits, including protection against type 2 diabetes and liver disease. 

Chocolate: Dark chocolate is believed to improve cardiovascular health by acting like a natural anti-inflammatory to reduce blood pressure.

 French version (largely modified)


Beurre: vous pouvez manger du beurre car les graisses saturées en quantité raisonnable n'augmentent pas le risque de maladie cardiovasculaire (MCV)
Fromage: 
En particulier les fromages d'alpage contiennent des graisses qui peuvent diminuer le risque de MCV
Les yaourts et autres produits allégés: 
outre le fait que les graisses saturées (qui ont été enlevées) des produits laitiers peuvent améliorer le profil de risque, l'addition systématique de sucre favorise la prise de poids et le diabète type 2
Vin rouge: consommé isolément il n'améliore pas le profil de risque biologique, ce n'est que combiné à l'exercice physique qu'une telle amélioration se produit
Café: loin d'être défavorable à la santé la consommation de café peut abaisser le risque de syndrome métabolique, de diabète type 2 et de surcharge graisseuse du foie
Chocolat: le chocolat noir diminue la pression artérielle, est antioxydant et améliore l'artérite des membres inférieurs. Lui attribuer une pastille couleur défavorable parait inapproprié.
