Catalano, A, Morabito, N, Basile, G, Cucinotta, D, Lasco, A
European journal of clinical investigation. 2015;(2):144-9
Abstract
BACKGROUND Low vitamin D serum levels have been associated with unfavourable lipid profile and poorer response to atorvastatin. Aims of this study were to test the effects of 25-hydroxyvitamin D3 (calcifediol) compared to parental vitamin D3 (cholecalciferol) supplementation on modifications of plasma 25(OH)D levels and lipid profile. MATERIALS AND METHODS Fifty-seven postmenopausal women (aged 59.03 ± 6.73 years) who were at low risk of fracture and with basal plasma 25(OH)D < 30 ng/mL were included if they were on atorvastatin treatment prescribed as appropriate. Recruited women were randomized to receive oral calcifediol or cholecalciferol, both at a dose of 140 μg according to a weekly regimen. RESULTS At baseline, 25(OH)D was negatively associated with BMI (r = -0.37; P = 0.004), total cholesterol (r = -0.31; P = 0.01) and LDL-C (r = -0.32; P = 0.02). After 24 weeks, 25(OH)D increased significantly in both groups (P < 0.001), although higher levels were obtained with calcifediol as compared with cholecalciferol (P < 0.001). Only in the calcifediol group, a significant reduction of LDL-C (P = 0.01) and an increase of HDL-C (P = 0.02) were obtained, even after adjustment for age, and baseline BMI, 25(OH)D and lipid levels (P < 0.05). The percentage changes in 25(OH)D levels were associated with the variations of LDL-C (r = -0.44; P = 0.01) and HDL-C levels (r = 0.30; P = 0.10). CONCLUSION Calcifediol administration in osteopenic and dyslipidemic postmenopausal women with low 25(OH)D improves lipid profile when added to an ongoing atorvastatin treatment.

Zhen ci yan jiu = Acupuncture research. 2015;(1):61-4
Abstract
OBJECTIVE To observe the clinical effect of acupuncture therapy combined with Lipitor in the treatment of primary hyperlipidemia (spleen deficiency and food stagnation type). METHODS Sixty primary hyperlipidemia patients (spleen deficiency and food stagnation type) were equally randomized into medication group and acupuncture plus medication group. Patients of both groups were treated by oral administration of Lipitor (20 mg/tablet, one tablet per day) for 6 weeks. Manual acupuncture stimulation was applied to Baihui (GV 20), Zhongwan (CV 12), and bilateral Zusanli (ST 36), Sanyinjiao (SP 6), Yin-lingquan (SP 9) and Fenglong (ST 40) for 40 min, twice daily for 6 weeks except the weekends. Serum total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) were detected by using a full-automatic biochemistry analyzer before and after the treatment. The therapeutic effect was assessed according to the standards described in "Guide Principles for Clinical Researches of New Chinese Herbal Drugs". RESULTS After the treatment, the levels of serum TC, TG of the two groups were significantly decreased in comparison with pre-treatment in the same one group (P<0.05), and the therapeutic effect of the acupuncture+medication group was significantly superior to that of simple medication group in lowering serum TC, TG and LDL-C levels and heightening HDL-C levels (P<0.05). Of the two 30 cases in the medication and acupuncture+medication groups, 2 (6.7%) and 7 (23.3%) were basically controlled in their blood-lipid levels, 10 (33.3%) and 15 (50.0%) had a marked improvement, 10 (33.3%) and 6 (20.0%) were improved, and 8 (26.7%) and 2 (6.7%) were invalid, with the effective rates being 73.3% and 93.3%, respectively. CONCLUSION Acupuncture combined with administration of Lipitor is effective in improving primary hyperlipidemia in patients, which is superior to administration of simple Lipitor.

Abstract
BACKGROUND Dyslipidaemia remains a significant risk factor for cardiovascular disease and additional lipid-modifying treatments are warranted to further decrease the cardiovascular disease burden. We assessed the safety, tolerability and efficacy of a novel cholesterol esterase transfer protein (CETP) inhibitor TA-8995 in patients with mild dyslipidaemia. METHODS In this randomised, double-blind, placebo-controlled, parallel-group phase 2 trial, we recruited patients (aged 18-75 years) from 17 sites (hospitals and independent clinical research organisations) in the Netherlands and Denmark with fasting LDL cholesterol levels between 2·5 mmol/L and 4·5 mmol/L, HDL cholesterol levels between 0·8 and 1·8 mmol/L and triglyceride levels below 4·5 mmol/L after washout of lipid-lowering treatments. Patients were randomly allocated (1:1) by a computer-generated randomisation schedule to receive one of the following nine treatments: a once a day dose of 1 mg, 2·5 mg, 5 mg, or 10 mg TA-8995 or matching placebo; 10 mg TA-8995 plus 20 mg atorvastatin; 10 mg TA-8995 plus 10 mg rosuvastatin or 20 mg atorvastatin or 10 mg rosuvastatin alone. We overencapsulated statins to achieve masking. The primary outcome was percentage change in LDL cholesterol and HDL cholesterol from baseline at week 12, analysed by intention to treat. This study is registered with ClinicalTrials.gov, number NCT01970215. FINDINGS Between Aug 15, 2013, and Jan 10, 2014, 364 patients were enrolled. At week 12, LDL cholesterol levels were reduced by 27·4% in patients assigned to the 1 mg dose, 32·7% in patients given the 2·5 mg dose, 45·3% in those given the 5 mg dose, and 45·3% in those given the 10 mg dose (p<0·0001). LDL cholesterol levels were reduced by 68·2% in patients given 10 mg TA-8995 plus atorvastatin, and by 63·3% in patients given rosuvastatin plus 10 mg TA-8995 (p<0·0001). A daily dose of 1 mg TA-8995 increased HDL cholesterol levels by 75·8%, 2·5 mg by 124·3%, 5 mg by 157·1%, and 10 mg dose by 179·0% (p<0·0001). In patients receiving 10 mg TA-8995 and 20 mg atorvastatin HDL cholesterol levels increased by 152·1% and in patients receiving 10 mg TA-8995 and 10 mg rosuvastatin by 157·5%. We recorded no serious adverse events or signs of liver or muscle toxic effects. INTERPRETATION TA-8995, a novel CETP inhibitor, is well tolerated and has beneficial effects on lipids and apolipoproteins in patients with mild dyslipidaemia. A cardiovascular disease outcome trial is needed to translate these effects into a reduction of cardiovascular disease events. FUNDING Dezima.

Abstract
BACKGROUND This represents the first update of this review, which was published in 2012. Atorvastatin is one of the most widely prescribed drugs and the most widely prescribed statin in the world. It is therefore important to know the dose-related magnitude of effect of atorvastatin on blood lipids. OBJECTIVES Primary objective To quantify the effects of various doses of atorvastatin on serum total cholesterol, low-density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL)-cholesterol and triglycerides in individuals with and without evidence of cardiovascular disease. The primary focus of this review was determination of the mean per cent change from baseline of LDL-cholesterol. Secondary objectives • To quantify the variability of effects of various doses of atorvastatin.• To quantify withdrawals due to adverse effects (WDAEs) in placebo-controlled randomised controlled trials (RCTs). SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 11, 2013), MEDLINE (1966 to December Week 2 2013), EMBASE (1980 to December Week 2 2013), Web of Science (1899 to December Week 2 2013) and BIOSIS Previews (1969 to December Week 2 2013). We applied no language restrictions. SELECTION CRITERIA Randomised controlled and uncontrolled before-and-after trials evaluating the dose response of different fixed doses of atorvastatin on blood lipids over a duration of three to 12 weeks. DATA COLLECTION AND ANALYSIS Two review authors independently assessed eligibility criteria for studies to be included and extracted data. We collected information on withdrawals due to adverse effects from placebo-controlled trials. MAIN RESULTS In this update, we found an additional 42 trials and added them to the original 254 studies. The update consists of 296 trials that evaluated dose-related efficacy of atorvastatin in 38,817 participants. Included are 242 before-and-after trials and 54 placebo-controlled RCTs. Log dose-response data from both trial designs revealed linear dose-related effects on blood total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides. The Summary of findings table 1 documents the effect of atorvastatin on LDL-cholesterol over the dose range of 10 to 80 mg/d, which is the range for which this systematic review acquired the greatest quantity of data. Over this range, blood LDL-cholesterol is decreased by 37.1% to 51.7% (Summary of findings table 1). The slope of dose-related effects on cholesterol and LDL-cholesterol was similar for atorvastatin and rosuvastatin, but rosuvastatin is about three-fold more potent. Subgroup analyses suggested that the atorvastatin effect was greater in females than in males and was greater in non-familial than in familial hypercholesterolaemia. Risk of bias for the outcome of withdrawals due to adverse effects (WDAEs) was high, but the mostly unclear risk of bias was judged unlikely to affect lipid measurements. Withdrawals due to adverse effects were not statistically significantly different between atorvastatin and placebo groups in these short-term trials (risk ratio 0.98, 95% confidence interval 0.68 to 1.40). AUTHORS' CONCLUSIONS This update resulted in no change to the main conclusions of the review but significantly increases the strength of the evidence. Studies show that atorvastatin decreases blood total cholesterol and LDL-cholesterol in a linear dose-related manner over the commonly prescribed dose range. New findings include that atorvastatin is more than three-fold less potent than rosuvastatin, and that the cholesterol-lowering effects of atorvastatin are greater in females than in males and greater in non-familial than in familial hypercholesterolaemia. This review update does not provide a good estimate of the incidence of harms associated with atorvastatin because included trials were of short duration and adverse effects were not reported in 37% of placebo-controlled trials.

Abstract
A line of epidemiological studies suggests that the accumulation of coronary risk factors promotes the progression of coronary atherosclerosis. Recent clinical studies showed that aggressive low-density lipoprotein (LDL) cholesterol-lowering therapy using statins could regress coronary atheroma and reduce major cardiovascular events. Additionally, therapy that controlled amlodipine-based blood pressure reduced major cardiovascular events in patients with hypertension compared with an atenolol-based regimen. An open-label randomized multicenter study is primarily planned to evaluate the changes in coronary atheroma volume using intravascular ultrasonography 18-24 months after intensive lowering of LDL-cholesterol and blood pressure compared with a standard therapy indicated by current guidelines in Japanese patients with coronary artery disease (CAD). The secondary endpoints include changes in serum lipid levels, inflammatory markers, glucose markers and blood pressure. In total, 100 subjects with CAD who are undergoing percutaneous coronary intervention will be tested. The MILLION study will provide new evidence and therapeutic standards for the prevention of CAD in Japanese patients by controlling both LDL-C levels and blood pressure.

Abstract
OBJECTIVE This open randomized study compares the effects of 24-week-long treatment with rosuvastatin and with atorvastatin coadministered with ezetimibe on the parameters of carbohydrate metabolism and the plasma levels of adipokynes in patients with coronary artery disease and type 2 diabetes mellitus or impaired glucose tolerance (IGT). METHOD A total of 31 patients with coronary artery disease and type 2 diabetes mellitus or IGT were recruited in the study. Patients were randomized into two groups: group 1 included patients who received rosuvastatin therapy in an average dose of 12.5 mg/day (n = 16); group 2 included patients who received combination treatment with atorvastatin in an average dose of 13.3 mg/day and ezetimibe (10 mg) (n = 15). Plasma levels of lipids, apoB, apoA1, glucose, insulin, leptin, and adiponectin were evaluated; HOMA-IR index (an empty stomach insulin, mu/l x fasting glucose, mmol/l)/22.5) was calculated. RESULTS During the therapy, the LDL-C and apoB levels decreased by 51.7% and 42.3% in group 1 and by 51.8% and 44.9% in group 2, respectively. Reduction in the triglyceride levels was significantly more pronounced in group 2 than in group 1: 43.2% vs 17.4% (p < 0.02), whereas we did not observed significant changes of HDL-C and apoA1 in either group. The increases in basal glycemia, basal insulinemia, HbA1c levels (from 6.47% [6.10-7.02%] to 6.98% 16.23-8.18%]), and HOMA-IR (from 2.14 [1.68-3.51] to 4.30 [2.31-5.77]) were found only in group 2 (p < 0.05 for all). These changes were observed in 75% of patients of group 2 independently of the presence of diabetic state or IGT, but the changes were more pronounced in patients with disturbed carbohydrate metabolism. Changes of leptin levels during the therapy were diverse: 73% patients of group 1 demonstrated decrease in the leptin levels, whereas 67% of patients in group 2 experienced 57%-increase in the leptin concentrations. Degree of increased basal glycemia was associated with increase in the leptin levels (r = 0.37, p = 0.04) in the entire group of patients (n = 31). Furthermore, changes in leptin levels were negatively associated with decreased adiponectin levels (r = -0.57, p = 0.034). CONCLUSIONS In case of equivalent degree of the decrease in LDL-C levels, 24-week combination therapy with atorvastatin and ezetimibe, unlike rosuvastatin treatment, induced increases in basal glycemia, insulinemia, HbA1c, and HOMA-IR index irrespective of the presence of carbohydrate metabolism disturbances before treatment. Our data suggest that adiponectin and leptin are involved in the mechanisms of adverse metabolic effects of the combination of atorvastatin and ezetimibe.

Abstract
OBJECTIVES Our aim was to assess the effects of the cholesteryl ester transfer protein (CETP) inhibitor anacetrapib and atorvastatin, both as monotherapy and in combination, on particle concentrations of low-density lipoproteins (LDL), very low-density lipoproteins (VLDL), and intermediate-density lipoproteins in dyslipidemic patients. BACKGROUND Although increases in high-density lipoproteins with CETP inhibition are well-documented, effects on atherogenic lipoprotein particle subclasses in dyslipidemic patients have not been extensively characterized. METHODS Ion mobility was performed on stored plasma samples collected from patients before and after treatment with anacetrapib alone (150 and 300 mg/d) or in combination with atorvastatin (20 mg/d) in a previously conducted 8-week phase IIb study. RESULTS Anacetrapib produced significant placebo-adjusted reductions of total LDL particles and all subfractions except for increases in very small LDL 4a and 4b. Atorvastatin reduced all LDL subfractions except LDL 4b. Results were generally additive for anacetrapib + atorvastatin. For patients treated with anacetrapib, the placebo-adjusted reduction in LDL 3a was attenuated and there was an increase in LDL 3b and 4a for those with low vs high triglyceride (TG) levels. For the atorvastatin alone vs placebo treatment comparison, there were small reductions in LDL 3a, 3b, and 4a for those with low vs high TG levels. CONCLUSIONS Anacetrapib and atorvastatin produced similar reductions from baseline in total LDL particles, but did not have comparable effects on all LDL particle subfractions, and neither drug reduced the smallest LDL 4b particles. The clinical significance of these changes and the differential effects on very small LDL 4a in patients with higher vs lower TG remain to be determined (clinicaltrials.gov, NCT00325455).

[In what extend we can reach the current LDL-cholesterol treatment goals in secondary prevention].
Mayer, O, Bruthans, J, ,
Vnitrni lekarstvi. 2015;(5):439-46
Abstract
BACKGROUND A number of clinical trials have shown that patients with overt atherovascular disease may benefit from more aggressive dosage of statins. We aimed to determined the usual dosage of statin in clinical practice and the adherence to recommended target concentration of LDL-cholesterol. METHODS AND RESULTS We analyzed 948 patients with mean age 64.5 years (SD ± 9.0) after acute coronary syndrome and/or coronary revascularization (Czech samples of EUROASPIRE III and IV). In spite that more than 93 % of patients were in 2012/2013 treated with statin, only 2.4 % with the highest dose (atorvastatin 80 mg or equivalent). On the other hand, medium-dosed statin (atorvastatin 40 mg) was more often prescribed, in comparison to 2006/2007. We observed mild improvement in adherence to former LDL-cholesterol target < 2.5 mmol/l (from 54 % to 65 %), but the recent target < 1.8 mmol/l was reached only in less than one quarter of patients in 2012/2013. It can be approximate (using individual LDL-cholesterol values), that after maximal possible up-titration of statin, the adherence to recent LDL-cholesterol target may improve up to 43 %. CONCLUSIONS Although the majority of CHD patients are currently being treated with statin, the usual dosage regimen and adherence to the recommended target values were not consistent with current therapeutic standards for secondary prevention of CHD.

Heart (British Cardiac Society). 2015;(5):356-62
Abstract
OBJECTIVES To study whether high-dose versus usual-dose statin treatment reduces the incidence of peripheral artery disease (PAD) and what is the effect of high-dose statin treatment on cardiovascular disease (CVD) outcome in patients with PAD. METHODS AND RESULTS In the Incremental Decrease in End Points Through Aggressive Lipid Lowering trial, 8888 post-myocardial infarction patients were randomised to high-dose or usual-dose statin therapy (atorvastatin 80 mg/day vs simvastatin 20-40 mg/day). We investigated the effect of high-dose versus usual-dose statins on the pre-specified outcome PAD incidence, and additionally performed a posthoc analysis of the efficacy of high-dose statins in reducing CVD risk among patients with PAD. During a median follow-up of 4.8 years, 94 patients (2.2%) receiving atorvastatin and 135 patients (3.2%) receiving simvastatin developed PAD (HR=0.70, 95% CI 0.53 to 0.91; p=0.007). The risk of major coronary events was almost twofold higher in patients with PAD at baseline, but was no longer significant after adjusting for the adverse cardiovascular risk profile. In PAD patients, major coronary events occurred in fewer patients in the atorvastatin group (14.4%) than in the simvastatin group (20.1%), but the difference did not reach statistical significance. (HR=0.68, 95% CI 0.41 to 1.11; p=0.13). Atorvastatin treatment significantly reduced overall cardiovascular (p=0.046) and coronary events (p=0.004), and coronary revascularisation (p=0.007) in these patients. CONCLUSIONS High-dose statin therapy with atorvastatin significantly reduced the incidence of PAD compared with usual-dose statin therapy with simvastatin. Patients with a history of PAD at baseline were at higher risk of future coronary events and this risk was reduced by high-dose atorvastatin treatment.

Abstract
OBJECTIVE To observe the effects of different loading doses of atorvastatin calcium on the outcomes of percutaneous coronary intervention (PCI) in elderly patients with coronary heart disease (CHD). METHODS A total of 120 CHD patients aged over 80 years were randomly assigned into 3 equal groups to receive intensive pretreatment with statin at the doses of 20, 40, or 60 mg prior to PCI performed within 48 to 72 h after admission. The changes of postoperative cardiac biochemical markers including creatine kinase isoenzyme (CKMB), troponin I (cTNI) and high-sensitivity c-reactive protein (hs-CRP) were observed and the incidence of major adverse cardiac events (MACE, including cardiac death, myocardial infarction, and target vessel revascularization) were recorded within 30 days after PCI. RESULTS Thirty-four patients in 20 mg statin group, 40 in 40 mg statin group, and 38 in 60 mg statin group completed this study. In all the 3 groups, hs-CRP level significantly increased at 12 and 24 h after PCI compared with the preoperative levels (P<0.05). The patients in 60 mg statin group showed significantly lower levels of CKMB, cTNI, and hs-CRP at 24 h after PCI than those in 20 mg statin group (P<0.05), and had also a significantly lower incidence of total MACE within 30 days after PCI (2.6% vs 26.5%, P=0.003) resulting primarily from significantly reduced myocardial infarction associated with PCI (2.6% vs 20.6%, P=0.016). The adverse drug reactions were comparable among the 3 groups (P>0.05). CONCLUSIONS Intensive pretreatment with 60 mg/day atorvastatin calcium can significantly reduce myocardial infarction related to PCI with good safety in elderly patients with CHD.
