Abstract
PURPOSE Coffee is rich in bioactive compounds with health beneficial properties, with green coffee presenting higher phenol content than roasted. We evaluated the effects of regularly consuming realistic amounts of a green/roasted coffee blend on cardiovascular health-related biomarkers. METHODS A randomized, cross-over, controlled study was carried out in 25 normocholesterolemic [total cholesterol (TC) < 200 mg/dL] and 27 hypercholesterolemic (TC 200-240 mg/dL) subjects. During 8 weeks, volunteers consumed 6 g/day of soluble green/roasted (35:65) coffee or a control beverage (water or an isotonic drink). Blood pressure, heart rate and body weight were monitored at the end of each intervention, and serum lipids [TC, HDL-C, LDL-C, VLDL-C, triglycerides and phospholipids], cytokines and chemokines (IL-1β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-10, IL-12, IL-13, IL-17, G-CSF, GM-CSF, MCP-1, MIP-1β, TNF-α, INF-γ), adhesion molecules (ICAM-1, VCAM-1), and C-reactive protein were measured. Plasma antioxidant capacity (FRAP, ORAC and ABTS methods), and lipid (malondialdehyde, MDA) and protein (carbonyl groups, CG) oxidation were also determined. RESULTS Attending to the general lineal model of variance for repeated measures, after the green/roasted coffee intervention significant reductions in TC, LDL-C, VLDL-C and triglycerides levels (p = 0.006, 0.001, 0.003 and 0.017, respectively), and a significant group effect were observed (0.001, < 0.001, 0.019 and 0.027, respectively). Only within the hypercholesterolemic group, attending to the Bonferroni test, the aforementioned lipid parameters were significantly lower after regular green/roasted coffee intake compared to baseline values. Moreover, after the coffee stage, plasma antioxidant capacity improved, according to the increase in ORAC and FRAP values (p < 0.001 and p < 0.001, respectively) and decrease of MDA (p = 0.015) and CG (p < 0.001) levels, without differences between groups. Systolic (p = 0.001) and diastolic (p < 0.001) blood pressure, heart rate (p = 0.035), and body weight (p = 0.017) were reduced in both normo- and hypercholesterolemic groups. CONCLUSION Regular consumption of moderate amounts of a soluble green/roasted (35:65) coffee blend may contribute to improve cardiovascular health in moderately hypercholesterolemic people, as reducing serum lipids, blood pressure and body weight effects, as well as increasing plasma antioxidant capacity, have been observed. Moreover, positive influences on blood pressure, body weight, and plasma antioxidant capacity were obtained in the healthy group. Therefore, incorporation of green coffee beans into the coffee brew can be recommended as part of a dietary strategy to protect from cardiovascular disease.

Abstract
BACKGROUND Evolocumab and other anti-PCSK9 antibodies reduced adverse cardiovascular outcomes in clinical trials of high-risk patients over <3 years median treatment duration. OBJECTIVES The OSLER-1 trial (Open Label Study of Long Term Evaluation Against LDL-C Trial) evaluated longer-term effects of evolocumab during open-label hypercholesterolemia treatment for up to 5 years. METHODS Patients randomized to standard of care (SOC) or evolocumab 420 mg monthly (evolocumab + SOC) for year 1. After year 1, patients could enter the all-evolocumab period and receive evolocumab + SOC for an additional 4 years. The authors analyzed the persistence of lipid effects and exposure-dependent safety focusing on yearly rates of adverse events (AEs) and anti-drug antibodies over 4.951 patient-years of observation. RESULTS A total of 1,255 patients (safety analysis population) randomized into the year 1 SOC-controlled period and received ≥1 evolocumab dose (mean ± SD age 57 ± 12 years; 53% female). A total of 1,151 patients (efficacy analysis population) progressed to the all-evolocumab period (year 2 and beyond). Evolocumab + SOC persistently lowered mean ± SE low-density lipoprotein cholesterol (LDL-C) by 56% ± 0.6% (n = 1,071), 57% ± 0.8% (n = 1,001), 56% ± 0.8% (n = 943), and 56% ± 0.8% (n = 803) after approximately 2, 3, 4, and 5 years, respectively, from randomization. Mean baseline LDL-C decreased from 140 to 61 mg/dl on treatment. Yearly serious AE rates during evolocumab + SOC ranged from 6.9% to 7.9%, comparable to the 6.8% rate in SOC patients during year 1. Evolocumab discontinuation due to AEs occurred in 5.7% of patients. Two SOC and 2 evolocumab + SOC patients developed new, transient, binding anti-drug antibodies; no neutralizing antibodies were observed. CONCLUSIONS The OSLER-1 trial demonstrated consistently excellent LDL-C-lowering efficacy, tolerance, and safety of evolocumab, with no neutralizing antibodies detected, throughout the longest-duration study of a PCSK9 inhibitor reported to date.

Abstract
INTRODUCTION Atherosclerotic cardiovascular disease (ASCVD) and its clinical manifestations, remain a leading cause of death and disability worldwide. One of the major risk factors of ASCVD is dyslipidemia and all the available guidelines suggest the importance of strategies for lipid control in a remarkable proportion of the general population. AREAS COVERED This review focuses on the therapeutic options available for the management of lipid disorders in adults. EXPERT OPINION A large body of evidence supports that statins are still the first-line option for the management of hypercholesterolemia in a large percentage of patients. Statins should be given at the appropriate dose and considering the differences in lipid-lowering potency across the different medications. The main current challenge in the treatment of lipid disorders is the need of improving patient adherence and persistence to lipid-lowering treatments beyond the drug choice and the target lipid component. To achieve this goal, the best strategy would be to treat the patients by using the appropriate drugs given at adequate doses to reach the treatment target. We should also avoid drug interactions, monitor possible untoward side effects and promote adherence to treatment by tailoring treatment strategies to each patient.

Abstract
PURPOSE OF REVIEW Lipoprotein apheresis is a very efficient but time-consuming and expensive method of lowering levels of low-density lipoprotein cholesterol, lipoprotein(a)) and other apoB containing lipoproteins, including triglyceride-rich lipoproteins. First introduced almost 45 years ago, it has long been a therapy of "last resort" for dyslipidaemias that cannot otherwise be managed. In recent years new, very potent lipid-lowering drugs have been developed and the purpose of this review is to define the role of lipoprotein apheresis in the current setting. RECENT FINDINGS Lipoprotein apheresis still plays an important role in managing patients with homozygous FH and some patients with other forms of hypercholesterolaemia and cardiovascular disease. In particular, patients not achieving treatment goals despite modern lipid-lowering drugs, either because these are not tolerated or the response is insufficient. Recently, lipoprotein(a) has emerged as an important cardiovascular risk factor and lipoprotein apheresis has been used to decrease lipoprotein(a) concentrations in patients with marked elevations and cardiovascular disease. However, there is considerable heterogeneity concerning the recommendations by scientific bodies as to which patient groups should be treated with lipoprotein apheresis. Lipoprotein apheresis remains an important tool for the management of patients with severe drug-resistant dyslipidaemias, especially those with homozygous FH.

Abstract
BACKGROUND AND AIMS Lipid disorders are often detected very late, particularly in affected young children. We evaluated the feasibility of a screening for LDL-hypercholesterolemia (highLDL) among toddlers and preschoolers. METHODS Population-based screening has been offered to all children (2-6 years) living in the State of Lower Saxony, Germany, with capillary blood sampling for detection of elevated LDL-cholesterol (LDL-C ≥ 135 mg/dL). Positive results were confirmed by a second measurement. Follow-up in specialized centers, including disease specific counselling and extended diagnostics, as well as evaluation of psychological distress of the parents, is carried out longitudinally. RESULTS Up to March 2018, 5656 children have participated in the screening program. 5069/5656 children have completed the screening for highLDL (52.0% boys; median age: 4.0 years [Interquartile range, IQR 3.0-5.1]; mother age: 35 years [IQR 31-38]; father's age: 37 years; [IQR 33-42]). HighLDL was identified in 112 children (2.2%; 40.2% boys; LDL-C 157.6 ± 29.5 mg/dL, mean ± SD). In the total cohort, parents stated in 40.9% of the cases a positive family history for hyperlipidemia and in 29.9% a premature cardiovascular event. Children with highLDL had more often both risk factors in their family history; however, in 37% of them none of these factors were reported. CONCLUSIONS The first results of the screening program showed its feasibility and revealed high prevalence of highLDL in the general population. Furthermore, a large proportion of families of affected children were not aware about their lipid disorders.

Abstract
Walnut consumption can provide both vascular and metabolic health benefits, and walnut-induced changes in lipoprotein particle chemical payloads may be responsible for these health benefits. To explore this possibility with a focus on metabolic health, this study investigated the impact of walnut consumption on lipoprotein lipid composition and changes in LDL anti-inflammatory properties, as reported by inflamed adipocyte. Hypercholesterolemic, postmenopausal females were treated with 40 g/day (i.e., 1.6 servings/day; n=15) of walnuts for 4 weeks. Fatty acids and their oxygenated metabolites, i.e., oxylipins, were quantified in isolated lipoproteins. Human primary adipocytes were exposed to LDL and TNFα-stimulated adipokine production was measured. Walnut treatment elevated α-linolenic acid and its epoxides in all lipoproteins and depleted mid-chain alcohols in VLDL and LDL, but not HDL. Walnuts also reduced TNFα-induced diabetic adipocyte production of IL-6 (-48%, P=.0006) and IL-8 (-30%, P=.01), changes inversely correlated with levels of α-linolenic acid-derived epoxides but not α-linolenic acid itself. In conclusion, modest walnut consumption can alter lipoprotein lipid profiles and enhance their ability to inhibit TNFα-dependent pro-inflammatory responses in human diabetic primary adipocytes. Moreover, this study suggests the oxylipins, rather than the parent fatty acids, mediate LDL action of adipocytes.

Abstract
Gut microbiota has been suggested to affect lipid metabolism. The objective of this study was to characterize the faecal microbiota signature and both short chain fatty acids (SCFAs) and bile acids (BA) profile of hypercholesterolemic subjects. Microbiota composition, SCFAs, BA and blood lipid profile from male volunteers with hypercholesterolemia (HC) and normocholesterolemia (NC) were determined by 16S rDNA sequencing, HPLC, GC and NMR, respectively. HC subjects were characterized by having lower relative abundance of Anaeroplasma (0.002% vs 0.219%, p-value = 0.026) and Haemophilus (0.041% vs 0.078%, p-value = 0.049), and higher of Odoribacter (0.51% vs 0.16%; p-value = 0.044). Correlation analysis revealed that Anaeroplasma and Haemophilus were associated to an unfavourable lipid profile: they correlated negatively to cholesterol and triglycerides related biomarkers and the ratio total to high density lipoprotein (HDL) cholesterol, and positively to HDL size. Odoribacter displayed an opposite behaviour. Faecal SCFAs profile revealed higher abundance of isobutyric (2.76% vs 0.82%, p-value = 0.049) and isovaleric acid (1.32% vs 0.06%, p-value = 0.016) in HC. Isobutyric acid correlated positively with Odoribacter and lipid parameters indicative of an unfavourable profile. BA profile did not show differences between groups. It was concluded that HC subjects showed a particular faecal bacterial signature and SCFAs profile associated with their lipid profile.

[New perspectives in the treatment of hypercholesterolaemia since the availability of PCSK9 inhibitors].
Pintó, X, Sarasa, I
Hipertension y riesgo vascular. 2019;(4):213-220
Abstract
The large clinical trials on cardiovascular prevention have demonstrated that the more atherogenic cholesterol is reduced the greater the preventive benefit, and neither a threshold value below which that effect disappears nor negative effects on health have been observed. Therefore, the objectives of hypercholesterolaemia control in patients at high cardiovascular risk are becoming ever stricter. The fact that most high-risk patients do not achieve these objectives requires, among other measures, rational use of available lipid-lowering drugs, including monoclonal antibodies that inhibit the protein PCSK9 (PCSK9i). The PCSK9i that are currently licensed for clinical use, evolocumab and alirocumab, have shown high potency in lowering LDL-cholesterol, which can exceed 60%, and other favourable effects on lipid profiles, including a very marked reduction of non-HDL cholesterol and apolipoproteinB. Likewise, through large-scale clinical trials, both drugs have demonstrated a preventive effect against cardiovascular diseases, and a high degree of safety. In addition, in the case of alirocumab, a reduction in all-cause mortality has been observed. However, the high cost of the PCSK9i means that prescription is restricted to patients at highest cardiovascular risk who cannot be controlled with high-potency statins and ezetimibe. It is to be hoped that the new guidelines that are to be issued soon by various scientific societies will define in greater detail the patients and the conditions in which we can use PCSK9i, drugs which currently constitute the greatest advance in hypercholesterolaemia of recent decades.
