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).

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
OBJECTIVES We prospectively compared the preventive effects of rosuvastatin and atorvastatin on contrast-induced nephropathy (CIN) in patients with chronic kidney disease (CKD) undergoing percutaneous coronary intervention (PCI). METHODS We enrolled 1078 consecutive patients with CKD undergoing elective PCI. Patients in Group 1 (n = 273) received rosuvastatin (10 mg), and those in group 2 (n = 805) received atorvastatin (20 mg). The primary end-point was the development of CIN, defined as an absolute increase in serum creatinine ≥0.5 mg/dL, or an increase ≥25% from baseline within 48-72 h after contrast medium exposure. RESULTS CIN was observed in 58 (5.4%) patients. The incidence of CIN was similar in patients pretreated with either rosuvastatin or atorvastatin (5.9% vs. 5.2%, p = 0.684). The same results were also observed when using other definitions of CIN. Clinical and procedural characteristics did not show significant differences between the two groups (p>0.05). Additionally, there were no significant inter-group differences with respect to in-hospital mortality rates (0.4% vs. 1.5%, p = 0.141), or other in-hospital complications. Multivariate logistic regression analysis revealed that rosuvastatin and atorvastatin demonstrated similar efficacies for preventing CIN, after adjusting for potential confounding risk factors (odds ratio = 1.17, 95% confidence interval, 0.62-2.20, p = 0.623). A Kaplan-Meier survival analysis showed that patients taking either rosuvastatin or atorvastatin had similar incidences of all-cause mortality (9.4% vs. 7.1%, respectively; p = 0.290) and major adverse cardiovascular events (29.32% vs. 23.14%, respectively; p = 0.135) during follow-up. CONCLUSIONS Rosuvastatin and atorvastatin have similar efficacies for preventing CIN in patients with CKD undergoing PCI.

Abstract
BACKGROUND Low-density lipoprotein cholesterol (LDL-C) is a major cardiovascular risk. However, some patients show symptoms of coronary heart disease (CHD) even though their LDL-C is strictly controlled. Therefore, it is important to treat other risk factors. METHODS Some 129 outpatients with dyslipidemia who were treated with either atorvastatin 10 mg/day (ATO), pitavastatin 2 mg/day (PIT), or rosuvastatin 2.5 mg/day (ROS) were enrolled. After informed consent was obtained, these patients were switched to another statin. Lipid profiles and lipoprotein fraction by polyacrylamide gel electrophoresis (PAGE) were compared between before and after 3 months of treatment with non-fasting blood sample. RESULTS LDL-C did not show any significant changes after switching and was maintained around 2.59 mmol/L in all groups. High-density lipoprotein cholesterol (HDL-C) was significantly increased in group ATO→PIT (1.43→1.54 mmol/L, p = 0.0010) and ROS→PIT (1.46→1.57 mmol/L, p = 0.0004), and was significantly decreased in group PIT→ATO (1.44→1.36 mmol/L, p = 0.0290). Apolipoprotein A-I (Apo A-I) and preheparin lipoprotein lipase (LPL) mass showed similar changes in HDL-C. Changes in HDL-C showed a significant positive correlation with those in Apo A-I and preheparin LPL mass, and a little but significant negative correlation with changes in Lp(a) and intermediate density lipoprotein (IDL) fraction. CONCLUSIONS ATO, PIT, and ROS have comparable effect on LDL-C lowering. Changes in HDL-C were similar to those in Apo A-I and preheparin LPL mass, and PIT was the most effective treatment in increasing HDL-C, Apo A-I, and preheparin LPL mass.

Abstract
The phase 3 ODYSSEY OPTIONS studies (OPTIONS I, NCT01730040; OPTIONS II, NCT01730053) are multicenter, multinational, randomized, double-blind, active-comparator, 24-week studies evaluating the efficacy and safety of alirocumab, a fully human monoclonal antibody targeting proprotein convertase subtilisin/kexin type 9, as add-on therapy in ∼ 650 high-cardiovascular (CV)-risk patients whose low-density lipoprotein cholesterol (LDL-C) levels are ≥100 mg/dL or ≥70 mg/dL according to the CV-risk category, high and very high CV risk, respectively, with atorvastatin (20-40 mg/d) or rosuvastatin (10-20 mg/d). Patients are randomized to receive alirocumab 75 mg via a single, subcutaneous, 1-mL injection by prefilled pen every 2 weeks (Q2W) as add-on therapy to atorvastatin (20-40 mg) or rosuvastatin (10-20 mg); or to receive ezetimibe 10 mg/d as add-on therapy to statin; or to receive statin up-titration; or to switch from atorvastatin to rosuvastatin (OPTIONS I only). At week 12, based on week 8 LDL-C levels, the alirocumab dose may be increased from 75 mg to 150 mg Q2W if LDL-C levels remain ≥100 mg/dL or ≥70 mg/dL in patients with high or very high CV risk, respectively. The primary efficacy endpoint in both studies is difference in percent change in calculated LDL-C from baseline to week 24 in the alirocumab vs control arms. The studies may provide guidance to inform clinical decision-making when patients with CV risk require additional lipid-lowering therapy to further reduce LDL-C levels. The flexibility of the alirocumab dosing regimen allows for individualized therapy based on the degree of LDL-C reduction required to achieve the desired LDL-C level.

Abstract
BACKGROUND Little is known about the differences between standard-dose statins effects on glucose level and lipids in Japanese patients with diabetes mellitus (DM). METHODS AND RESULTS The 1,049 patients were randomly assigned to either the rosuvastatin group or atorvastatin group. There were no significant differences between the 2 groups in the effect on non-high-density lipoprotein cholesterol (non-HDL-C) and HbA1c at 12 months. However, physicians tended to switch to more intensive therapy for DM in the atorvastatin group. CONCLUSIONS Rosuvastatin 5 mg and atorvastatin 10 mg have a similar lowering effect on non-HDL-C, but might be different in terms of adverse effect on glucose levels.

Bochar, OM
Wiadomosci lekarskie (Warsaw, Poland : 1960). 2014;(2 Pt 2):157-60
Abstract
The results of investigations had showed the high efficiency of the combination of atorvastatin with telmisartan in patients with arterial hypertension combined with obesity and NAFLD. Such combined treatment had led to a significant decrease of cholesterol levels (p < 0.01), LDL cholesterol (p < 0.05) and TG (p < 0.01), helped to decrease in SBP of 159.75 ± 3,00 to 137.50 ± 1,38 mm Hg (< 0.01), DBP from 93.75 ± 1,57 to 79.25 ± 0,90 mm Hg ( < 0.001), and thus made it possible to significantly improve the health of patients and reduce the risk of cardiovascular complications. According 13C-methacetin breath test, this combination positively influences the lipid metabolism and improves the metabolic function of the liver. One of the mechanisms of action of telmisartan may be its indirect impact on adipokines system, which was demonstrated by an increase in the rate of metabolism and growth of indices of cumulative doses on 40 and 120 minutes.

Journal of lipid research. 2013;(11):3189-97
Abstract
No indices are currently available to facilitate clinicians to identify patients who need either statin monotherapy or statin-ezetimibe combined treatment. We aimed to investigate whether cholesterol synthesis and absorption markers can predict the cholesterol-lowering response to statin. Total 306 statin-naïve patients with high risk of coronary heart disease (CHD) were treated with atorvastatin 20 mg/day for 1 month. Cholesterol synthesis and absorption markers and LDL cholesterol (LDL-C) levels were measured before and after treatment. Atorvastatin decreased LDL-C by 36.8% (range: decrease of 74.5% to increase of 31.9%). Baseline cholesterol synthesis marker lathosterol and cholesterol absorption marker campesterol codetermined the effect of atorvastatin treatment. The effect of cholesterol lowering by atorvastatin was significantly associated with baseline lathosterol levels but modified bidirectionally by baseline campesterol levels. In patients with the highest baseline campesterol levels, atorvastatin treatment decreased cholesterol absorption by 46.1%, which enhanced the effect of LDL-C lowering. Atorvastatin treatment increased cholesterol absorption by 52.3% in those with the lowest baseline campesterol levels, which attenuated the effect of LDL-C reduction. Especially those with the highest lathosterol but the lowest campesterol levels at baseline had significantly less LDL-C reduction than those with the same baseline lathosterol levels but the highest campesterol levels (27.3% versus 42.4%, P = 0.002). These results suggest that combined patterns of cholesterol synthesis/absorption markers, rather than each single marker, are potential predictors of the LDL-C-lowering effects of atorvastatin in high-risk CHD patients.

Abstract
INTRODUCTION The efficacy and safety of single-pill amlodipine/atorvastatin for reducing blood pressure (BP), low-density lipoprotein cholesterol (LDLC), and predicted 10-year cardiovascular (CV) risk have been demonstrated in low CV risk countries. The Slovak Trial on Cardiovascular Risk Reduction Following National Guidelines with CaDUET® (amlodipine besylate/atorvastatin calcium; Pfizer, Morrisville, PA, USA; STRONG DUET) study evaluated its clinical utility in Slovakia, one of the highest CV risk regions in Europe. METHODS This was a two-phase study involving 100 outpatient cardiologist and internist departments in Slovakia. Phase 1 assessed BP control and CV risk profiles in adults with treated hypertension, and phase 2 was an open-label, multicenter, observational study. In the phase 2 study, patients with treated but uncontrolled hypertension and three or more coronary heart disease risk factors received single-pill amlodipine/atorvastatin (5/10 or 10/10 mg) for 12 weeks. Major outcomes were the percentage of patients achieving target BP (≤140/90 mmHg) and/or LDL-C (≤3 mmol/L) and reductions in predicted 10-year CV risk. RESULTS Of the 4,672 phase 1 patients, 80.8% had uncontrolled hypertension and 61.4% had dyslipidemia. Of the 1,406 phase 2 patients, 90.3% of patients achieved target BP at week 12, 66.3% achieved target LDL-C, and 60.7% achieved both. The mean 10-year CV risk was reduced by 49% (P < 0.0001); treatment was well-tolerated and safe. CONCLUSION Single-pill amlodipine/atorvastatin was associated with significant improvements in BP, LDL-C target attainment, and 10-year CV risk in patients with uncontrolled hypertension in Slovakia. The treatment was well-tolerated and safe. Use of single-pill amlodipine/atorvastatin in high CV-risk countries could lead to significant improvements in CV risk management.

The review of diabetic studies : RDS. 2013;(2-3):213-22
Abstract
OBJECTIVES There is extensive but controversial evidence on the diverse effects of statins on the level of high-density lipoprotein cholesterol (HDL-C). Some of these effects may limit the benefits of statins in terms of cardiovascular risk reduction. To identify the conditions for beneficial effects, this study investigated the response to atorvastatin and simvastatin treatment in type 2 diabetic patients with elevated low-density lipoprotein cholesterol (LDL-C). METHODS 2,872 subjects with type 2 diabetes from a disease management program were investigated. Patients with LDL-C ≥130 mg/dl or total cholesterol ≥200 mg/dl were put onto statin therapy by the National Health Insurance system in Taiwan. RESULTS 1,080 patients who completed 1 year of statin treatment were analyzed. There were significant reductions in LDL-C in both the atorvastatin (37.1%) and simvastatin (34.3%) group after one year of treatment compared with baseline levels. Unexpectedly, the majority of diabetic patients who received atorvastatin or simvastatin did not show an increase in HDL-C levels. 59.8% of patients had a significant HDL-C reduction (ΔHDL-C ≤ -3%) after atorvastatin treatment. Multivariate logistic regression analysis showed that the following patients were at higher risk of HDL-C reduction after 12 months: (i) patients in whom statin therapy was initiated aged <65 years and who had a BMI ≥24 kg/m(2), (ii) male patients with a baseline HDL-C >40 mg/dl, and (iii) female patients with a baseline HDL-C >50 mg/dl. However, diabetic patients with severe atherogenic dyslipidemia (LDL-C ≥130, TG ≥204, and HDL-C ≤34 mg/dl) obtained more benefits in terms of HDL-C change after statin therapy. CONCLUSIONS Diabetic patients, except those with severe atherogenic dyslipidemia, are prone to a decrease in serum HDL-C level after statin treatment, particularly after atorvastatin treatment.
