ezetimibe--simvastatin-drug-combination and Metabolic-Syndrome

In a randomized, double-blind, crossover study of 15 aspirin-naive patients (mean age 48.8 ± 10.2 years) with the metabolic syndrome, statin monotherapy (simvastatin 40 mg daily) was compared to combination therapy (simvastatin 40 mg and ezetimibe 10 mg daily) on biomarkers of inflammation and platelet activity. The addition of ezetimibe to simvastatin over a 4-week period was associated with reduced expression of CD141 (thrombomodulin; p = 0.02), platelet endothelial cell adhesion molecule (p < 0.0001) and CD51/61 (vitronectin receptor; p = 0.048) compared to statin monotherapy. Ezetimibe added to simvastatin improves several indices of platelet reactivity beyond statin monotherapy. However, the clinical relevance of these findings await results of the IMPROVE-IT trial (Improved Reduction of Outcomes: Vytorin Efficacy International Trial).

Low-dose statin therapy in combination with ezetimibe, an inhibitor of intestinal cholesterol absorption, lowers plasma LDL-cholesterol levels to a similar degree as high-dose statin monotherapy. This study assessed whether similar LDL-cholesterol lowering with simvastatin/ezetimibe combination therapy improves fasting and postprandial arterial endothelial function compared to high-dose statin therapy alone.. Multicenter, double-blind, crossover trial in 100 abdominally obese patients with the metabolic syndrome, randomized to 6 weeks' treatment with simvastatin 80 mg or simvastatin/ezetimibe 10/10 mg. Flow mediated dilatation (FMD) and peripheral arterial tonometry (EndoPAT) as well as plasma lipids were measured in the fasting state and after an oral lipid load at baseline and after both treatments.. Fasting LDL-cholesterol levels (3.57 mmol/L at baseline) were reduced to 1.79 mmol/L following treatment with simvastatin 80 mg and 1.81 mmol/L with simvastatin/ezetimibe 10/10 mg, respectively. Plasma lipids were similar at 4 h after an oral lipid load following both treatments for 6 weeks. Fasting endothelial function was also similar with both treatments when assessed by FMD (adjusted mean ± SE: 4.35 ± 0.19 vs. 4.43 ± 0.18; P = 0.777) and EndoPAT (2.12 ± 0.05 vs 2.20 ± 0.05; P = 0.304). After an oral fat load, changes in endothelial function were also comparable for both treatments as assessed by FMD (-0.34 ± 0.21 vs. -0.43 ± 0.20; P = 0.766) and EndoPAT (0.00 ± 0.07 vs. -0.04 ± 0.08; P = 0.712).. Treatment with simvastatin/ezetimibe 10/10 mg induced no difference in endothelial function in the fasting and postprandial state compared to simvastatin 80 mg while attaining similar LDL-c levels in obese patients with metabolic syndrome.

The objective was to assess the consistency of effect of switching to ezetimibe/simvastatin 10/20 mg versus doubling the baseline statin dose (to simvastatin 40 mg or atorvastatin 20 mg) or switching to rosuvastatin 10 mg across subgroups of subjects with (n = 617) and without (n = 191) metabolic syndrome (MetS).. This was a post hoc analysis of a randomized, double-blind, 6-week study of adults 18-79 years with cardiovascular disease and diabetes mellitus with low-density lipoprotein cholesterol (LDL-C) ≥70 and ≤160 mg/dl. The percent change in LDL-C and other lipids was estimated within each subgroup separately. Safety and tolerability were assessed.. In subjects with MetS, percent changes in LDL-C and other lipids were greater with ezetimibe/simvastatin versus doubling baseline statin or numerically greater versus switching to rosuvastatin, except high-density lipoprotein cholesterol and apolipoprotein (Apo) AI (mean percent changes in LDL-C were: -22.49% ezetimibe/simvastatin, -9.64% doubled baseline statin and -19.20% rosuvastatin). In subjects without MetS, percent changes in LDL-C, total cholesterol and Apo B were greater with ezetimibe/simvastatin versus doubling baseline statin or numerically greater versus switching to rosuvastatin (mean percent changes in LDL-C were: -25.14% ezetimibe/simvastatin, -4.75% doubled baseline statin and -19.75% rosuvastatin). Safety profiles were generally similar.. These results showed that switching to ezetimibe/simvastatin 10/20 mg was more effective at reducing LDL-C, total cholesterol and Apo B versus doubling the baseline statin dose to simvastatin 40 mg or atorvastatin 20 mg or switching to rosuvastatin 10 mg regardless of MetS status. These results were generally similar to those of the full cohort.

Metabolic syndrome (MetS) is a clustering of atherosclerotic coronary heart disease risk factors. This post-hoc analysis compared the effects of switching to ezetimibe/simvastatin 10/20 mg or rosuvastatin 10 mg in a cohort of 618 high-risk hypercholesterolaemic patients with (n=368) and without (n=217) MetS who had previously been on statin monotherapy. Patients were randomised 1:1 to double-blind ezetimibe/simvastatin 10/20 mg or rosuvastatin 10 mg for 6 weeks. Least squares mean percent change from baseline and 95% confidence intervals in lipid efficacy parameters were calculated for the population and within subgroups. Treatment with ezetimibe/simvastatin was significantly more effective than rosuvastatin at lowering low-density lipoprotein cholesterol, total cholesterol, non- high-density lipoprotein cholesterol, and apolipoprotein B (all p<0.001). No significant differences in treatment effects were seen between the presence and absence of MetS. In this post-hoc analysis of high-risk hypercholesterolaemic patients the lipid-reducing effects of ezetimibe/simvastatin or rosuvastatin were not altered significantly by the presence of MetS.

To investigate relationships between baseline factors and treatment-associated efficacy changes in type 2 diabetes.. AND METHODS Multivariable analyses of treatment response in 1,229 type 2 diabetic patients with hypercholesterolemia who received ezetimibe/simvastatin or atorvastatin in a randomized double-blind 6-week study.. Increasing age was related to improvements in all lipid assessments. Men had greater triglyceride and non-HDL cholesterol reductions than women, and black/Hispanic patients had less favorable lipid effects than other races/ethnicities. Increasing baseline LDL cholesterol was associated with improvements in most lipids; higher baseline non-HDL cholesterol with improved HDL cholesterol and triglycerides; higher baseline HDL cholesterol with greater non-HDL cholesterol and high-sensitivity C-reactive protein (hs-CRP) reductions; and higher baseline hs-CRP with smaller LDL cholesterol, non-HDL cholesterol, and apolipoprotein B reductions. Patients with high baseline non-HDL cholesterol or triglycerides less frequently attained LDL cholesterol targets. Obesity was inversely related to HDL cholesterol and hs-CRP changes, and higher baseline A1C to smaller apolipoprotein B reductions. Metabolic syndrome was not a significant predictor.. Treatment responses in type 2 diabetic patients were related to baseline factors, although treatment effects (ezetimibe/simvastatin being more effective than atorvastatin) remained consistent. The presence of predictive factors should be considered in planning lipid-altering therapy.

To assess the efficacy and safety of ezetimibe/simvastatin (E/S) plus extended-release niacin (N) in hyperlipidaemic patients with diabetes mellitus (DM), metabolic syndrome (MetS) without DM (MetS/non-DM) or neither (non-DM/non-MetS).. A subgroup analysis of a double-blind, 64-week trial of 1220 randomized patients who received E/S (10/20 mg) + N (to 2 g) or E/S (10/20 mg) for 64 weeks, or N (to 2 g) for 24 weeks then E/S (10/20 mg) + N (2 g) or E/S (10/20 mg) for 40 additional weeks. The evaluable populations of this analysis included n = 765 patients at 24 weeks and n = 574 at 64 weeks. Among those receiving N, only those who attained the 2-g dose were included in the analysis.. E/S+N improved levels of low-density lipoprotein cholesterol, other lipids and lipoprotein ratios compared with N and E/S at 24 weeks and E/S at 64 weeks. The combination increased high-density lipoprotein cholesterol and apolipoprotein AI comparably to N and more than E/S. E/S+N reduced high-sensitivity C-reactive protein (hsCRP) levels more effectively than N and similarly to E/S. E/S+N was generally well tolerated. Discontinuations due to flushing with N and E/S+N were comparable and greater than E/S in all subgroups. Fasting glucose trended higher for N vs. E/S. Glucose elevations from baseline to 12 weeks were highest for patients with DM (24.9 mg/dl for N, 21.2 mg/dl for E/S+N, 17.5 mg/dl for E/S); fasting glucose then declined to pretreatment levels at 64 weeks in all subgroups. New-onset DM was more frequent among MetS patients than those without MetS during the first 24 weeks and trended higher among those assigned to N-containing regimens [n = 5(5.1%) for N, n = 2(1.7%) for E/S, n = 21(8.8%) for E/S+N]; during the 24-64 week extension study, diabetes was diagnosed in five additional patients in the E/S(cumulative incidence of 5.9%) and one in the E/S+N (cumulative incidence of 9.2%). Treatment-incident elevations in uric acid levels were increased among subjects assigned to N-containing regimens, but there were no effects on symptomatic gout.. Combination E/S+N is a safe treatment option for hyperlipidaemic patients including those with DM and MetS, but requires monitoring of glucose and potentially uric acid levels.

Patients with diabetes mellitus (DM) and metabolic syndrome are at increased risk of coronary heart disease (CHD). Studies have shown differential statin efficacy on low-density lipid cholesterol (LDL-C) by CHD risk strata.. The aim of this study was to evaluate the consistency of effect with ezetimibe/simvastatin (E/S) combination therapy, atorvastatin, or rosuvastatin in patients with DM, metabolic syndrome, or neither condition (No DM/metabolic syndrome), stratified by the National Cholesterol Education Panel Adult Treatment Panel III (NCEP ATP III) CHD risk group.. Post hoc analyses of 2 multicenter, double-blind, randomized, 6-week studies comparing E/S 10/10, 10/20, 10/40, or 10/80 mg with either atorvastatin 10, 20, 40, or 80 mg, or rosuvastatin 10, 20, or 40 mg. Treatments were compared by pooling across all doses for LDL-C reduction and NCEP LDL-C goal attainment in patients with DM, metabolic syndrome without DM, or No DM/metabolic syndrome across NCEP CHD risk strata.. NCEP LDL-C goal attainment was lowest in the high-risk group with atherosclerotic vascular disease (12-64%) and greatest in the moderate and low-risk groups (84-100%). In contrast, LDL-C reduction was generally similar irrespective of disease or risk subgroup. All treatments were generally well tolerated, with overall similar safety regardless of disease and risk level.. In these studies, CHD risk strata were inversely related to the likelihood of attaining NCEP LDL-C goals, but did not appear to affect the percentage LDL-C change from baseline. This demonstrates the need for especially aggressive cholesterol lowering necessary to reach the lower LDL-C goal for high-risk patients.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases all over the world. In patients with a high cardiovascular risk the decrease of cholesterol level is especially important. The primary goal of this study is to observe the safety and efficacy of combined ezetimibe / simvastatin treatment and simvastatin monotherapy in patients with NAFLD and high cardiovascular risk disease. The secondary goal of this investigation was to compare the safety and efficacy of combined ezetimibe / simvastatin treatment with simvastatin monotherapy.. The data of 45 patients with NAFLD associated with type2 diabetes and metabolic syndrome were examined. They were diagnosed and treated in Budaörs Health Centre between 2005 and 2008. Twenty-six of the patients were treated with simvastatin (20 mg/day) and 19 individuals were given ezetimibe / simvastatin therapy (10/10 mg). The safety (aspartate-aminotransferase-AST-, alanine-aminotransferase-ALT- and creatine kinase-CK-values) and efficacy (cholesterol, low density lipoprotein-LDL- cholesterol, high density lipoprotein-HDL- cholesterol and triglyceride) of the treatments had been studied for six months of the treatment period.. Ezetimibe/simvastatin treatment resulted in a significant decrease in ALT (63.78+/-5.12 vs 32.57+/-3.92 U/L; p<0.0001) and AST (50.79+/-3.66 vs 23.68+/-3.42 U/L; p<0.0001). Simvastatin monotherapy also yielded significant decrease in ALT (66.58+/-6.13 vs 29.46+/-4.07 U/L; p<0.0001) and AST (59.61+/-5.97 vs 24.00+/-3.87 U/L; p<0.0001). Comparing the two treatment groups, simvastatin monotherapy reduced ALT (37.11+/-8.01 vs 31.21+/-7.08 U/L; p<0.0112) and AST (35.61+/-7.20 vs 27.10+/-5.22 U/L; p
