The introduction of Proprotein covertase subtilisin/kexin type 9 (PCSK9) inhibitors has been heralded as a major advancement in reducing low-density lipoprotein cholesterol levels by nearly 50%. However, concerns have been raised on the added value to the health care system in terms of their costs and benefits. We assess the cost-effectiveness of PCSK9 inhibitors based on a decision-analytic model with existing clinical evidence. The model compares a lipid-lowering therapy based on statin plus PCSK9 inhibitor treatment with statin treatment only (standard therapy)...

BACKGROUND: Pharmacological prophylaxis has been proven to reduce the risk of cardiovascular events in individuals with atherosclerotic occlusive arterial disease. However, the role of prophylaxis in individuals with abdominal aortic aneurysm (AAA) remains unclear. Several studies have shown that despite successful repair, those people with AAA have a poorer rate of survival than healthy controls. People with AAA have an increased prevalence of coronary heart disease and risk of cardiovascular events...

Lipoprotein (a) [Lp(a)] is an low-density lipoprotein (LDL)-like particle with an additional apolipoprotein, apolipoprotein (a), [apo(a)] attached to apolipoprotein B. Recent epidemiologic and Mendelian randomization studies have provided evidence that Lp(a) is causally related to the pathogenesis of atherosclerosis and cardiovascular disease (CVD). The risk association between Lp(a) concentrations and CVD is still controversial but seems to be continuous and without an obvious threshold Lp(a) level. Circulating concentrations of Lp(a) are genetically determined; desirable levels are amplt; 50 mg/dl...

Gold nanoparticles are promising materials for many applications that include imaging, drug delivery, and photothermal therapy. However, AuNPs can be unstable and/or toxic. We purposed to improve the stability and reduce toxicity of gold nanorods (AuNR) upon coating with biocompatible polymer, chitosan-ceramide (CS-CE), without replacing the original layer, CTAB. CS-CE-coated AuNR was prepared by simple mixing for 24 h and purified by centrifugation. The coating was confirmed by UV-Vis absorption analysis and surface charge and size measurement...

Rapamycin slows organismal aging and delays age-related diseases, extending lifespan in numerous species. In cells, rapamycin and other rapalogs such as everolimus suppress geroconversion from quiescence to senescence. Rapamycin inhibits some, but not all, activities of mTOR. Recently we and others demonstrated that pan-mTOR inhibitors, known also as dual mTORC1/C2 inhibitors, suppress senescent phenotype. As a continuation of these studies, here we investigated in detail a panel of pan-mTOR inhibitors, to determine their optimal gerosuppressive concentrations...

In 2015, more than 530 000 people were prescribed statins in Norway. Adverse effects from the musculoskeletal system as well as less specific side effects are frequently reported. The extent of these contrasts with observations made in randomised controlled studies which report the prevalence of such adverse effects as being in line with placebo. Breaks from drug treatment, low doses, switching medication and use of other lipid-lowering drugs are the most relevant approaches to dealing with adverse effects.

A recent meta-analysis demonstrated that statin therapy was associated with a risk of diabetes. The present study investigated whether the relative reduction in low-density lipoprotein cholesterol (LDL-c) was a good indicator of the risk of new-onset diabetes. We searched the PubMed, Embase, Cochrane Central Register, Lilacs, Food and Drug Administration, and European Medicines Agency databases for randomized controlled trials of statins. Fourteen trials were included in the study. Eight trials with target LDL-c levels ≤100 mg/dL (2...

BACKGROUND: Statins represent a pivotal treatment in coronary artery disease, offering a reduction in cardiovascular risk even beyond their lipid-lowering action. However, the mechanism of these "pleiotropic" benefits of statins is poorly understood. Vitamin D has been suggested as a potential mediator of the anti-inflammatory, anti-thrombotic and vascular protecting effects of statins. Aim of present study was to assess the impact of a high-intensity statin therapy on vitamin D levels and platelet function in patients with coronary artery disease...

Despite the effectiveness of statins in the treatment of lipid disorders, residual risk still exists, and hitherto studies where additional drugs were added to statin therapy have been mainly negative or the outcomes were very modest. Therefore there is still a need for new and effective oral agents in the combination therapy of lipid disorders. Areas Covered: The review covers the current state of knowledge on the mechanism of action of bempedoic acid (ETC-1002) and results from recent clinical studies. Expert Opinion: ETC-1002 is a novel oral lipid-lowering therapy...

BACKGROUND AND OBJECTIVE: Proprotein convertase subtilisin/kexin type 9 inhibition with monoclonal antibodies such as alirocumab significantly reduces low-density lipoprotein-cholesterol levels ± other lipid-lowering therapies. We aimed to develop and qualify a population pharmacokinetics (PopPK) model for alirocumab in healthy subjects and patients, taking into account the mechanistic target-mediated drug disposition (TMDD) process. METHODS: This TMDD model was developed using a subset of the alirocumab clinical trial database, including nine phase I/II/III studies (n = 527); the model was subsequently expanded to a larger data set of 13 studies (n = 2870)...

PURPOSE OF REVIEW: ATP-citrate lyase (ACLY) has re-emerged as a drug target for LDL cholesterol (LDL-C) lowering. We review ACLY as a therapeutic strategy, its genetics, its molecular and cellular biology, and also its inhibition. RECENT FINDINGS: ACLY is a critical enzyme linking glucose catabolism to lipogenesis by providing acetyl-CoA from mitochondrial citrate for fatty acid and cholesterol biosynthesis. Human genetic variants have been associated with enhanced growth and survival of several cancers, and with attenuated plasma triglyceride responses to dietary fish oil...

PURPOSE OF REVIEW: Human genetic studies have been successfully used to identify genes and pathways relevant to human biology. Using genetic instruments composed of loci associated with human lipid traits, recent studies have begun to clarify the causal role of major lipid fractions in risk of cardiometabolic disease. RECENT FINDINGS: The causal relationship between LDL cholesterol and coronary disease has been firmly established. Of the remaining two major fractions, recent studies have found that HDL cholesterol is not likely to be a causal particle in atherogenesis, and have instead shifted the causal focus to triglyceride-rich lipoproteins...

BACKGROUND: Osteocalcin, a protein synthesized by osteoblasts during the bone formation phase of bone remodeling, is used as a biomarker for the bone production process, and its serum levels are positively correlated with bone mineral density during treatment with anabolic bone drugs for osteoporosis. Higher fat mass has been shown to be a risk factor for osteoporosis and fragility fractures and body fat and bone interplay through several adipokines and bone-derived molecules, regulating bone remodeling, adipogenesis, body weight control, and glucose homeostasis...

Nonsteroidal anti-inflammatory drugs (NSAIDs) are one of the most widely used medications in the world for their analgesic, antipyretic, and anti-inflammatory actions, despite a well-known incidence of a wide spectrum of their adverse effects. To a great extent, beneficial action and side effects of NSAIDs are associated with the interaction of these drugs at the cell membrane level. Here, we use neutron scattering to combine elastic intensity scans, quasielastic and neutron spin echo (NSE) measurements to understand the effect of aspirin, a commonly used NSAID, on the dynamical and phase behavior of the membrane of dimyristoylphosphatidylcholine (DMPC), a prominent representative of phospholipids residing in the outer leaflet of the human erythrocyte membrane...

Dyslipidemias, especially hyper-low-density lipoprotein cholesterolemia and hypertriglyceridemia, are important causal risk factors for coronary artery disease. Comprehensive genotyping using the 'next-generation sequencing' technique has facilitated the investigation of Mendelian dyslipidemias, in addition to Mendelian randomization studies using common genetic variants associated with plasma lipids and coronary artery disease. The beneficial effects of low-density lipoprotein cholesterol-lowering therapies on coronary artery disease have been verified by many randomized controlled trials over the years, and subsequent genetic studies have supported these findings...

Importance: The Second Universal Definition of Myocardial Infarction (MI) divides MIs into different types. Type 1 MIs result spontaneously from instability of atherosclerotic plaque, whereas type 2 MIs occur in the setting of a mismatch between oxygen demand and supply, as with severe hypotension. Type 2 MIs are uncommon in the general population, but their frequency in human immunodeficiency virus (HIV)-infected individuals is unknown. Objectives: To characterize MIs, including type; identify causes of type 2 MIs; and compare demographic and clinical characteristics among HIV-infected individuals with type 1 vs type 2 MIs...
