Aronia berry polyphenol consumption reduces plasma total and low-density lipoprotein cholesterol in former smokers without lowering biomarkers of inflammation and oxidative stress: a randomized controlled trial.

Abstract
Former smokers are at increased risk for cardiovascular disease. We hypothesized that dietary aronia polyphenols would reduce biomarkers of cardiovascular disease risk, inflammation, and oxidative stress in former smokers. We also determined the extent these effects were associated with polyphenol bioavailability. A 12-week, randomized, placebo-controlled trial was conducted in 49 healthy adult former smokers (n = 24/placebo, n = 25/aronia) to evaluate if daily consumption of 500 mg aronia extract modulated plasma lipids, blood pressure, biomarkers of inflammation and oxidative stress, and lipid transport genes of peripheral blood mononuclear cells. The primary outcome was change in low-density lipoprotein cholesterol (LDL-C) from baseline, and multivariate correlation analysis was performed to determine if changes in lipids were associated with urinary polyphenol excretion. Aronia consumption reduced fasting plasma total cholesterol by 8% (P = .0140), LDL-C by 11% (P = .0285), and LDL receptor protein in peripheral blood mononuclear cells (P = .0036) at 12 weeks compared with the placebo group. Positive changes in the urinary polyphenol metabolites peonidin-3-O-galactoside, 3-(4-hydroxyphenyl) propionic acid, and unmetabolized anthocyanin cyanidin-3-O-galactoside were associated with lower plasma total cholesterol and LDL-C in the aronia group. Aronia consumption did not change blood pressure or biomarkers of inflammation and oxidative stress. Aronia polyphenols reduced total and LDL-C in former smokers but did not improve biomarkers of oxidative stress and chronic inflammation. The cholesterol-lowering activity of aronia extract was most closely associated with urinary levels of cyanidin-3-O-galactoside and peonidin-3-O-galactoside, its methylated metabolite. This trial was registered at ClinicalTrials.gov as NCT01541826.

Abstract
AIM We evaluated the evidence of pharmacogenetic associations with statins in a systematic review. METHODS Two separate outcomes were considered of interest: modification of low-density lipoprotein cholesterol (LDL-C) response and modification of risk for cardiovascular events. RESULTS In candidate gene studies, 141 loci were claimed to be associated with LDL-C response. Only 5% of these associations were positively replicated. In addition, six genome-wide association studies of LDL-C response identified common SNPs in APOE, LPA, SLCO1B1, SORT1 and ABCG2 at genome-wide significance. None of the investigated SNPs consistently affected the risk reduction for cardiovascular events. CONCLUSION Only five genetic loci were consistently associated with LDL-C response. However, as effect sizes are modest, there is no evidence for the value of genetic testing in clinical practice.

Abstract
Historically the efficacy and safety of statins has mostly been studied in western populations. Few such studies have been carried out in Asians until recent years. These studies revealed interesting similarities and differences for statin use between Asians and Caucasians. One clinically important question subsequently raised is whether Asians need lower statin doses compared with Caucasians. Many practicing physicians believe that statin doses are lower in Asians because of the generally lower bodyweight and BMI. Whether this belief is based on sound scientific evidence needs to be reviewed. Furthermore, since the decision of optimal dose is based on both efficacy and safety, both of which may be impacted by genetic factors, one may ask whether pharmacogenetics plays a role in the dose difference, if such a difference exists. There is a clinical need to critically and comprehensively article the literature to answer these questions, and summarize future directions of research in the field. This article serves the above purpose.

Abstract
Coronary heart disease (CHD) is the leading single cause of death in the United States and most Western countries, killing more than 400,000 Americans per year. Although CHD often manifests suddenly as a fatal myocardial infarction, the atherosclerosis that gives rise to the infarction develops gradually and can be markedly slowed or even reversed through pharmacological and lifestyle interventions. These same atherosclerotic processes also drive related vascular diseases such as stroke and peripheral artery disease, and individuals surviving occlusive events often develop additional complications including ischemic cardiomyopathy and heart failure. Therefore, better detection of subclinical atherosclerosis, along with more effective treatments, could significantly reduce the rate of death from CHD and related vascular diseases in the United States. In recent years, oxidation of polyunsaturated fatty acids (PUFAs) in plasma lipoproteins has been postulated to be a critical step in the development of atherosclerosis. If so, then monitoring lipid peroxidation should be a useful indicator of disease risk and progression. This review focuses on the evidence that specific PUFA peroxidation products, the F(2)-isoprostanes, are useful biomarkers that could potentially be utilized as indicators of CHD.
