Abstract
BACKGROUND Evolocumab significantly lowers low-density lipoprotein cholesterol (LDL-C) when dosed 140 mg every 2 weeks (Q2W) or 420 mg monthly (QM) subcutaneously. HYPOTHESIS LDL-C changes are comparable among different patient subgroups in a pooled analysis of data from phase 3 trials. METHODS A total of 3146 patients received ≥1 dose of evolocumab or control in four 12-week phase 3 studies. Percent change from baseline in LDL-C for evolocumab 140 mg Q2W or 420 mg QM vs control was reported as the average of week 10 and 12 values. Quantitative and qualitative interactions between treatment group and subgroup by dose regimen were tested. RESULTS In the pooled analysis, treatment differences vs placebo or ezetimibe were similar for both 140 mg Q2W and 420 mg QM doses across ages (<65 years, ≥65 years); gender; race (Asian, black, white, other); ethnicity (Hispanic, non-Hispanic); region (Europe, North America, Asia Pacific); glucose tolerance status (type 2 diabetes mellitus, metabolic syndrome, neither); National Cholesterol Education Program risk categories (high, moderately high, moderate, low); and European Society of Cardiology/European Atherosclerosis Society risk categories (very high, high, moderate, or low). Certain low-magnitude variations in LDL-C lowering among subgroups led to significant quantitative interaction P values that, when tested by qualitative interaction, were not significant. The incidences of adverse events were similar across groups treated with each evolocumab dosing regimen or control. CONCLUSIONS Consistent reductions in LDL-C were observed in the evolocumab group regardless of demographic and disease characteristics.

Abstract
BACKGROUND Evidence from observational studies have raised the possibility that statin treatment reduces the incidence of certain bacterial infections, particularly pneumonia. We analyzed data from a randomized controlled trial of rosuvastatin to examine this hypothesis. METHODS We analyzed data from the randomized, double-blind, placebo-controlled JUPITER trial (Justification for the Use of Statins in Prevention: an Intervention Trial Evaluating Rosuvastatin). In this trial, 17,802 healthy participants (men 50 years and older and women 60 and older) with a low-density lipoprotein (LDL) cholesterol level below 130 mg/dL (3.4 mmol/L) and a high-sensitivity C-reactive protein level of 2.0 mg/L or greater were randomly assigned to receive either rosuvastatin or placebo. We evaluated the incidence of pneumonia on an intention-to-treat basis by reviewing reports of adverse events from the study investigators, who were unaware of the treatment assignments. RESULTS Among 17,802 trial participants followed for a median of 1.9 years, incident pneumonia was reported as an adverse event in 214 participants in the rosuvastatin group and 257 in the placebo group (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.69-1.00). In analyses restricted to events occurring before a cardiovascular event, pneumonia occurred in 203 participants given rosuvastatin and 250 given placebo (HR 0.81, 95% CI 0.67-0.97). Inclusion of recurrent pneumonia events did not modify this effect (HR 0.81, 95% CI 0.67-0.98), nor did adjustment for age, sex, smoking, metabolic syndrome, lipid levels and C-reactive protein level. INTERPRETATION Data from this randomized controlled trial support the hypothesis that statin treatment may modestly reduce the incidence of pneumonia. (ClinicalTrials.gov trial register no. NCT0023968.).

Abstract
AIM: To assess the effects of long-term multifactorial intervention on renal function and serum uric acid (SUA) levels and their association with estimated cardiovascular disease (eCVD) risk and actual CVD events. METHODS This prospective, randomized, target-driven study included 1123 subjects (45.6% men, age 45-65 years) with metabolic syndrome (MetS) but without diabetes or CVD. Patients were randomized to multifactorial treatment. Atorvastatin was titrated from 10-80 mg/day aiming at a low density lipoprotein cholesterol (LDL-C) target of <100 mg/dl (group A) or an LDL-C target of <130 mg/dl (group B). Changes in estimated glomerular filtration rate (eGFR) and SUA levels were recorded in all patients and in the subgroup with stage 3 chronic kidney disease (CKD; eGFR = 30-59 ml/min/1.73 m(2); n = 349). We used ANOVA to compare changes within the same group, unpaired Student t-test to compare results between groups at specific time points, and log-rank test to compare event free survival. RESULTS The eCVD-risk reduction was greater in group A. In the overall study population, eGFR increased by 3.5% (p < 0.001) and SUA levels fell by 5.6% (p < 0.001). In patients from group A with stage 3 CKD (group A1; n = 172), eGFR increased by 11.1% (p < 0.001) from baseline and by 7.5% (p < 0.001) in group B1 (n = 177; p < 0.001 vs. the change in group A1). The corresponding fall in SUA levels was 10.7% in group A1 (p < 0.001 vs. baseline) and 8.3% in group B1 (p < 0.001 vs. baseline and group A1). These changes were mainly attributed to atorvastatin treatment. Among the CKD stage 3 patients there were no CVD events in group A1, while 6 events occurred in group B1 (p = 0.014). CONCLUSIONS Multifactorial intervention in patients with MetS without established CVD improved renal function and reduced SUA levels. These changes were more prominent in stage 3 CKD patients and might have contributed to the reduction in eCVD risk and clinical events.

Abstract
BACKGROUND The high prevalence of metabolic syndrome (MetS) has highlighted the need for effective dietary interventions to combat this growing problem. OBJECTIVE To assess the impact of a Mediterranean-style low-glycemic-load diet (control arm, n = 44) or the same diet plus a medical food containing phytosterols, soy protein, and extracts from hops and acacia (intervention arm, n = 45) on cardiometabolic risk variables in women with MetS. METHODS In this 12-week, 2-arm randomized trial, baseline, week 8 and 12, fasting blood samples were drawn to measure plasma lipids, apolipoproteins, and homocysteine. Dietary records were also collected and analyzed. RESULTS There were decreases in fat and sugar intake (P < .001 for both) and increases in docosahexaenoic acid and eicosapentaenoic acid intake (P < .001 for both) over time, consistent with the prescribed diet. Regarding MetS variables, there were decreases in waist circumference, systolic and diastolic blood pressure, and plasma triglycerides in all subjects (P < .001 for all) with no differences between arms. Plasma low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, apolipoprotein (apo) B, and apo B/apo A1 were reduced over time but to a greater extent in the intervention arm (P < .05 for all), indicating the medical food had a greater effect in altering lipoprotein metabolism. Further, medical food intake was associated with reduced plasma homocysteine (P < .01) compared to the control arm. CONCLUSION A Mediterranean-style low-glycemic-load diet effectively reduces the variables of MetS. Addition of the medical food results in a less atherogenic lipoprotein profile and lower plasma homocysteine.

Abstract
BACKGROUND Metabolic syndrome (MetS) and atherosclerotic vascular disease (AVD) are associated with increased coronary heart disease risk. OBJECTIVE To assess percent change from baseline in lipids and high-sensitivity C-reactive protein (hs-CRP) levels and the proportion of subjects reaching specified low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (HDL-C) and apolipoprotein B (Apo B) single, dual, and triple targets and hs-CRP <2 mg/L among subjects with and without AVD treated with ezetimibe/simvastatin or atorvastatin for 6 weeks. METHODS Adults (N = 1143) with MetS and hypercholesterolemia were randomized to starting and next higher doses of ezetimibe/simvastatin (10/20 or 10/40 mg) or atorvastatin (10, 20, or 40 mg). RESULTS Ezetimibe/simvastatin produced significantly greater reductions in evaluated lipids than atorvastatin for most prespecified dose comparisons. More subjects without AVD achieved LDL-C levels <100 mg/dL, non-HDL-C levels <130 mg/dL, and dual LDL-C/non-HDL targets (83%-92% vs 62%-76%) and Apo B <90 mg/dL or triple targets (65%-75% vs 41%-49%) with 40 mg of atorvastatin or 10/20-40 mg of ezetimibe/simvastatin compared with 10 or 20 mg of atorvastatin, respectively. More subjects with AVD achieved LDL-C<70 mg/dL and non-HDL-C<100 mg/dL single and dual targets (65%-80%) and Apo B <80 mg/dL (53%-63%) with 10/20-40 mg of ezetimibe/simvastatin than with 40 mg of atorvastatin (40%-49%). More subjects achieved triple lipid targets with 10/20-40 mg of ezetimibe/simvastatin versus 10-40 mg of atorvastatin (50%-63% vs 24%-40%). Achievement of hs-CRP <2 mg/L was similar across all doses regardless of AVD status. CONCLUSIONS More intensive therapy was required for >80% of subjects to achieve LDL-C <100 mg/dL and non-HDL-C <130 mg/dL and for the majority of subjects to achieve lower levels of LDL-C <70 mg/dL, non-HDL-C <100 mg/dL, and/or Apo B <90 mg/dL. The effect of ezetimibe on cardiovascular risk reduction has yet to be established. (Clintrials.gov no: NCT00409773).

Abstract
UNLABELLED The objective was to evaluate whether the soluble fibre Plantago ovata (Po)-husk improves cardiovascular disease (CVD) risk biomarkers including low-density lipoprotein cholesterol (LDL-C). METHODS In a multi-centred, double-blind, placebo-controlled, parallel, randomised trial conducted in primary care-clinics in Spain, France and Holland, mild-moderate hypercholesterolaemic patients (age range: 43-67 years) received 14 g/d of Po-husk (n=126) or placebo (microcrystalline-cellulose 14 g/d; n=128) in a low saturated fat diet for 8 weeks. Subsequently, if LDL-C remained > or = 3.35 mmol/L [130 mg/dL], participants proceeded with the fibre plus simvastatin (20mg/d) for further 8 weeks. Lipid profile, blood pressure (BP), insulin, oxidised LDL and some gene polymorphisms involved in CVD risk were measured. RESULTS Relative to placebo, Po-husk reduced plasma LDL-C by -6% (P<0.0002), total cholesterol (TC) by -6%, triglycerides (TG) by -21.6%, apolipoprotein (Apo) B-100 by -6.7%, oxidised LDL by a mean of -6.82 U/L (95%CI: 3.15-10.48), insulin by -4.68 pmol/L (95%CI: 0.68-8.67) and systolic BP by -4.0mm Hg (95%CI; 1.2-6.7) (P<0.05). The TG-lowering effect in the Po-husk group was magnified by variants in plasminogen-activator-inhibitor (PAI-1; rs1799768) and fatty acid-binding protein (FABP-2; rs1799883) genes. At 16 weeks, the intra-group action of simvastatin (20mg/d) added to Po-husk or placebo was a similar LDL-C reduction. CONCLUSIONS Po-husk, apart from lowering LDL-C, also reduced TG, TG related to certain gene variants, TC, Apo B-100, oxLDL, insulin-resistance and systolic BP in mild-moderate hypercholesterolaemic individuals. Thus, the target patients to receive Po-husk would be those who present a cluster of various CVD risk factors, such as metabolic syndrome.
