    Adhesion molecules and cytokines are involved in the pathogenesis of intimal injury in atherosclerosis but their relationship with endothelial function remains unclear. The objectives of this study were to examine the effects of atorvastatin on soluble adhesion molecules, interleukin-6 (IL-6) and brachial artery endothelial-dependent flow mediated dilatation (FMD) in patients with familial (FH) and non-familial hypercholesterolaemia (NFH). A total of 74 patients (27 FH and 47 NFH) were recruited. Fasting lipid profiles, soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular-cellular adhesion molecule-1 (sVCAM-1), E-selectin, IL-6 and FMD were measured at baseline, 2 weeks, 3 and 9 months post-atorvastatin treatment (FH--80 mg/day, NFH--10 mg/day). In both groups, compared to baseline, sICAM-1 levels were significantly reduced at 2 weeks, further reduced at 3 months and maintained at 9 months (P<0.0001). The IL-6 levels were significantly reduced at 3 months and 9 months compared to baseline for FH (P<0.005) and NFH (P<0.0001). In both groups, the FMD at 2 weeks was higher than baseline (P<0.005), with progressive improvement up to 9 months. FMD was negatively correlated with sICAM-1 and IL-6. In conclusion, both low and high doses of atorvastatin lead to early progressive improvement in endothelial function in patients with primary hypercholesterolaemia. sICAM-1 and IL-6 levels reflect endothelial dysfunction in these patients.

    BACKGROUND: Cardiovascular disease remains a leading cause of death worldwide, with hypercholesterolemia being a major risk factor. Evidence-based consensus guidelines have recommended consideration of increasingly stringent cholesterol-lowering goals, yet most patients do not meet these targets. Coronary heart disease (CHD) event and mortality rates and mean serum cholesterol levels have declined in Singapore in recent years; however, certain groups remain at elevated risk.

    OBJECTIVE: To determine (i) proportions of patients with CHD in Singapore who achieved goals for serum low-density lipoprotein-cholesterol (LDL-C); and (ii) factors influencing goal attainment.

    METHODS: A historical cohort study was conducted using records from the Singapore Cardiac Databank, a national registry of CHD patients. Serum LDL-C goal attainment was assessed in 5174 survivors of acute myocardial infarction or coronary revascularization (i.e. coronary artery bypass graft surgery or percutaneous coronary interventions), of whom 3811 (73.7%) were at very high risk.

    RESULTS: At baseline, the mean patient age was 60.3 years, mean serum value of total cholesterol was 228 mg/dL, and mean LDL-C was 163 mg/dL. Of all CHD patients, approximately 70% did not achieve a serum LDL-C target of <100 mg/dL. Most patients receiving HMG-CoA reductase inhibitor (statin) regimens were treated initially with low- to medium-equipotency regimens and were never titrated to stronger regimens. The vast majority (approximately 94%) of patients at very high risk did not achieve the stringent serum LDL-C target of <70 mg/dL. Patients receiving higher potency statins were significantly more likely to achieve LDL-C goals, whereas those with higher baseline LDL-C levels or Malaysian ethnicity were less likely to achieve LDL-C goals.

    CONCLUSIONS: Most CHD patients in the large group of Singapore residents with CHD in the present study did not achieve recommended LDL-C targets. A more effective disease-management approach, including patient education concerning lifestyle modification (e.g. diet, physical activity), efforts to enhance medication adherence, and more effective, well tolerated therapies such as high-equipotency or high-dose statins and statin combination regimens, may be needed to improve achievement of consensus cholesterol targets. This is the first study of cholesterol goal attainment in a large group of Southeast Asians and serves as a baseline for future evaluations in Asian populations.

    BACKGROUND: Data on achieving National Cholesterol Education Program Adult Treatment Panel III (ATP III) goals in Asia are limited.

    OBJECTIVE: To examine treatment patterns, goal attainment, and factors influencing treatment among patients in 6 Asian countries who were taking statins.

    METHODS: A retrospective cohort study was conducted in China, Korea, Malaysia, Singapore, Taiwan, and Thailand, where 437 physicians (41% cardiologists) recruited adults with hypercholesterolemia newly initiated on statin monotherapy.

    RESULTS: Of 2622 patients meeting inclusion and exclusion criteria, approximately 66% had coronary heart disease (CHD)/diabetes mellitus, 24% had no CHD but > or =2 risk factors, and 10% had no CHD and <2 risk factors. Most patients ( approximately 90%) received statins at medium or lower equipotency doses. Across all cardiovascular risk categories, 48% of patients attained ATP III targets for low-density lipoprotein cholesterol (LDL-C), including 38% of those with CHD/diabetes (goal: <100 mg/dL), 62% of those without CHD but with > or =2 risk factors (goal: <130 mg/dL), and 81% of those without CHD and <2 risk factors (goal: <160 mg/dL). Most patients who achieved goals did so within the first 3 months. Increasing age (odds ratio (OR)=1.015 per 1-year increment; 95% confidence interval (CI)=1.005-1.206; p=0.0038) and initial statin potency (OR=2.253; 95% CI=1.364-3.722; p=0.0015) were directly associated with goal attainment, whereas increased cardiovascular risk (OR=0.085; 95% CI=0.053-0.134; p<0.0001 for CHD/diabetes mellitus at baseline compared with <2 risk factors,) and baseline LDL-C (OR=0.990; 95% CI=0.987-0.993); p<0.0001 per 1-mg/dL increment) were inversely associated with LDL-C goal achievement. Limitations of this study include potential differences in treatment settings and cardiovascular risk factors between different countries and centers. In addition, the effects on cholesterol goal achievement of concomitant changes in lifestyle were not assessed.

    CONCLUSION: LDL-C goal attainment is low in Asians, particularly those with CHD/diabetes. More effective patient monitoring, treatments, including combining regimens and dose titration, and adherence to these treatments along with therapeutic lifestyle counseling may facilitate goal attainment.

    BACKGROUND: In a world of ever increasing health care costs, generic drugs represent a major opportunity to ensure access to essential medicines for people who otherwise would be unable to afford them. However, some clinicians and patients are still questioning the safety and effectiveness of generic formulations compared to the proprietary drugs necessitating further systematic research analyzing the generic drugs' efficacy. Our objective was to compare the lipid lowering effects of generic and branded atorvastatin.

    METHODS: This cross-sectional, retrospective cohort study was conducted at the University of Malaya Medical Centre from 1 May 2013 until 30 May 2013. We analyzed the lipid profiles (total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides) of 629 patients before and at least 3 months after switching them from proprietary atorvastatin (Lipitor®) to generic atorvastatin (atorvastatin calcium from Ranbaxy Laboratories, Inc.). We also investigated if there was any difference in the effectiveness of both atorvastatin formulations in various ethnic groups.

    RESULTS: 266 patients were included in this study. When comparing the median values we found no statistically significant differences (Wilcoxon signed-rank test; p drugs to their less expensive generic analogues.

    A considerable number of patients with severely elevated LDL-C do not achieve recommended treatment targets, despite treatment with statins. Adults at high cardiovascular risk with hypercholesterolemia and LDL-C ≥ 2.59 and ≤ 4.14 mmol/L (N = 250), pretreated with atorvastatin 20 mg were randomized to ezetimibe/simvastatin 10/40 mg or atorvastatin 40 mg for 6 weeks. The percent change in LDL-C and other lipids was assessed using a constrained longitudinal data analysis method with terms for treatment, time, time-by-treatment interaction, stratum, and time-by-stratum interaction. Percentage of subjects achieving LDL-C < 1.81 mmol/L, < 2.00 mmol/L, or < 2.59 mmol/L was assessed using a logistic regression model with terms for treatment and stratum. Tolerability was assessed.

    A multicentre study was conducted to assess the long term efficacy and safety of a generic atorvastatin in the treatment of primary hypercholesterolaemia. Eighty five patients who received 10mg or 20 mg of atorvastatin for 8 weeks depending on target cholesterol goal were followed up by their own physicians and had final evaluation at 52 weeks. Reduction in mean low density Lipoprotein (LDL-C) was 36.5%, 37.9% and 32.2% at weeks 4, 8 and 52 respectively. LDL-C target was maintained in 81% and 69% of patients at week 8 and 52 respectively without drug related serious adverse events. Generic atorvastatin is safe and effective in usual clinical care setting.

    A multicenter study was conducted to assess the efficacy of a generic form of Atorvastatin (Ranbaxy's Storvas) in the treatment of Primary Hypercholesterolemia. One hundred and nineteen patients were given 10 mg of Storvas for four weeks and increased to 20 mg if target LDL-Cholesterol was not achieved. LDL-Cholesterol was reduced by 36.6% at four weeks and 37.5% at eight weeks from baseline. Total cholesterol and triglycerides were significantly reduced. There were no drug-related serious adverse events. We conclude that the generic atorvastatin is safe and effective in the treatment of primary hypercholesterolaemia and the results are comparable to published data on innovator atorvastatin.

    BACKGROUND: Most studies investigating the benefits of statins have focused on North American and European populations. This study focuses on evaluating the lipid-lowering effects of rosuvastatin and atorvastatin in Asian patients.

    OBJECTIVES: The DIrect Statin COmparison of LDL-C Values: an Evaluation of Rosuvastatin therapY (DISCOVERY)-Asia study is one of nine independently powered studies assessing the efficacy of starting doses of statins in achieving target lipid levels in different countries worldwide. DISCOVERY-Asia was a 12-week, randomised, open-label, parallel-group study conducted in China, Hong Kong, Korea, Malaysia, Taiwan, and Thailand.

    RESULTS: A total of 1482 adults with primary hypercholesterolaemia and high cardiovascular risk (> 20%/10 years, type 2 diabetes, or a history of coronary heart disease) were randomised in a 2 : 1 ratio to receive rosuvastatin 10 mg once daily (o.d.) or atorvastatin 10 mg o.d. The percentage of patients achieving the 1998 European Joint Task Force low-density lipoprotein cholesterol (LDL-C) goal of < 3.0 mmol/L at 12 weeks was significantly higher in the rosuvastatin group (n = 950) compared with the atorvastatin group (n = 471) (79.5 vs. 69.4%, respectively; p < 0.0001). Similar results were observed for 1998 European goals for total cholesterol (TC), and the 2003 European goals for LDL-C and TC. LDL-C and TC levels were reduced significantly more with rosuvastatin compared with atorvastatin. Both drugs were well-tolerated and the incidence and type of adverse events were similar in each group.

    TRIALS REGISTRATION: The trial registry summary is available at http://www.clinicaltrials.gov/; ClinicalTrials.gov Identifier: NCT00241488

    CONCLUSIONS: This 12-week study showed that the starting dose of rosuvastatin 10 mg o.d. was significantly more effective than the starting dose of natorvastatin 10 mg o.d. at enabling patients with primary hypercholesterolaemia to achieve European goals for LDL-C and TC in a largely Asian population in real-life clinical practice. The safety profile of rosuvastatin 10 mg is similar to that of atorvastatin 10 mg in the Asian population studied here, and is consistent with the known safety profile of rosuvastatin in the white population.

    The enzyme 3-hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase is the key enzyme of the mevalonate pathway that produces cholesterol. Inhibition of HMG-CoA reductase reduces cholesterol biosynthesis in the liver. Synthetic drugs, statins, are commonly used for the treatment of hypercholesterolemia. Due to the side effects of statins, natural HMG-CoA reductase inhibitors of plant origin are needed. In this study, 25 medicinal plant methanol extracts were screened for anti-HMG-CoA reductase activity. Basella alba leaf extract showed the highest inhibitory effect at about 74%. Thus, B. alba was examined in order to investigate its phytochemical components. Gas chromatography with tandem mass spectrometry and reversed phase high-performance liquid chromatography analysis revealed the presence of phenol 2,6-bis(1,1-dimethylethyl), 1-heptatriacotanol, oleic acid, eicosyl ester, naringin, apigenin, luteolin, ascorbic acid, and α-tocopherol, which have been reported to possess antihypercholesterolemic effects. Further investigation of in vivo models should be performed in order to confirm its potential as an alternative treatment for hypercholesterolemia and related cardiovascular diseases.

    The main strategy for lowering blood cholesterol levels is through the inhibition of the NADPH-dependent HMG-CoA reductase (3-hydroxy-3-methyl-glutaryl-CoA reductase). The enzyme catalyses the reduction of HMG-CoA to mevalonate and this process is inhibited by statins that form the bulk of the therapeutic agents to treat high cholesterol since the 1970s. Newer drugs that are safer than statins are constantly being developed. The inhibition of candidate drugs to HMG-CoA reductase remains the mainstay of drug development research. The determination of the enzyme activity is important for the correct assessment of potency of the enzyme as well as determining the inhibition of potential therapeutic agents from the plant and microbial extracts. Also, this chapter covers the use of the popular four-parameter logistics model that can yield accurate estimation of the IC50 values of therapeutic agents and their 95% confidence intervals.

    There is little evidence to show that strict dietary modification alone confers any significant impact on cardiac events in primary and secondary prevention of coronary heart disease. Given the efficacy of the statins, the need for strict dietary modification in patients on statin therapy has been questioned. This study was performed to assess 1) the added benefit on serum lipid levels of a strict low-fat dietary regimen in patients with hypercholesterolaemia already treated with simvastatin; 2) the efficacy of simvastatin on the lipid profile of our sample Asian population; and 3) the tolerability and side-effect profile of simvastatin. This study was a prospective evaluation of 60 patients with hypercholesterolaemia treated with simvastatin who were subjected to either a normal diet or a dietitian guided low-fat diet. Assessment of the effects on serum lipid levels, side-effects, biochemical and haematological markers were performed. After 24 weeks of treatment, a strict dietitian guided low-fat diet conferred no additional benefit over and above what was achieved by simvastatin alone. Furthermore, a higher dose of simvastatin was needed in the dietitian guided diet group to achieve the target LDL-cholesterol level. Simvastatin resulted in a significant positive alteration of lipid profiles in all patients. The drug was well tolerated, with no significant change in either haematological or biochemical indices. Simvastatin is a highly effective cholesterol-lowering drug with a beneficial effect on the entire lipid spectrum in a cross-section of Asian patients, and is well tolerated. A dietitian guided dietary approach confers no additional advantage once statin therapy has been initiated.

    The landmark HMG-CoA reductase inhibitor (statin) studies have practical lessons for clinicans. The 4S trial established the importance of treating the hypercholesterolaemic patient with cardiovascular heart disease. Next, WOSCOPS showed the benefit of treating healthy, high-risk hypercholesterolaemic men. CARE, a secondary prevention trial, showed the benefit of treating patients with cholesterol levels within normal limits. This was confirmed by the LIPID trial, another secondary prevention study, which enrolled patients with cholesterol levels 155-271 mg/dl (4-7 mmol/l). The importance of treating patients with established ischaemic heart disease, and those at high risk of developing heart disease, regardless of cholesterol level, was being realized. In the MIRACL trial, hypocholesterolaemic therapy was useful in the setting of an acute coronary syndrome, while the AVERT study showed that aggressive statin therapy is as good as angioplasty in reducing ischaemic events in patients with stable angina. By showing the value of fluvastatin after percutaneous intervention, LIPS confirmed that benefit is a class action of the statins. The HPS randomized over 20 000 patients, and showed beyond doubt the value of statins in reducing cardiovascular events in the high-risk patient. Although PROSPER showed benefit in treating the elderly patients above 70 years, statin therapy in this trial was associated with an increase in cancer incidence. The comparative statin trials, PROVE-IT, REVERSAL, Phase Z of the A to Z, ALLIANCE and TNT, all showed that high-dose statins will better reduce cardiovascular events in the high-risk patient, although the adverse effects of therapy will also be increased. ALLHAT-LLT, ASCOT-LLA and CARDS showed that for statin therapy to demonstrate a significant benefit, hypertensive or diabetic patients must be at sufficiently high risk of cardiovascular events. The emphasis is now on the risk level for developing cardiovascular events, and treatment should target the high-risk group and not the lipid level of the patient. No therapy is free of adverse effect. Treatment of those most at risk will bring the most benefit; treatment of those not at high risk of cardiovascular disease may expose patients who would not benefit much from therapy to its adverse effects.

    This study aimed to evaluate the effect of kenaf seed oil (KSO), kenaf seed oil-in-water macroemulsion (KSOM), kenaf seed oil-in-water nanoemulsions (KSON), and emulsifier mixtures (EM) on serum lipid profile, liver oxidative status, and histopathological changes in high-cholesterol fed rats. Stability and characteristic of KSOM and KSON were carried out prior to in vivo study. Forty-two Sprague-Dawley rats were divided into 7 groups (6 rats each) and induced hypercholesterolemia by feeding high cholesterol diet (HCD) for 14 days prior to treatments. Different treatments were introduced on day 15 to 29 while supplemented with HCD and removal of HCD during treatment on day 30 to 43, except for HCD group. Body weight and serum lipid profiles were measured at 3 different points: after hypercholesterolemia was induced, on day 29, and at the end of the experiment. Relative liver weight, atherogenic index, coronary risk index, and fecal total bile acids were also determined at the end of experiment. KSON showed significantly higher stability than KSOM and FTIR exhibited good encapsulation of KSO after 1.5 years of storage. Serum total cholesterol, low density lipoprotein cholesterol, lipid peroxidation levels in HCD group without treatment were significantly higher compared to normal control group and all treatment groups. All samples demonstrated hypocholesterolemic effect, but KSON exhibited higher efficiency in cholesterol-lowering properties, weight control and decreased liver fat as confirmed by histopathological evaluation. The overall results revealed that the efficacy of different treatments was in descending order of KSON, KSO, KSOM, and EM.

    PRACTICAL APPLICATION: Kenaf seed oil-in-water nanoemulsion (KSON) has the potential to be used as a natural alternative to the synthetic hypocholesterolemic drug in the future. However, larger sample size and clinical trial are needed to confirm on this potential application. In addition, treatment with KSON was suggested to prevent cardiovascular disease and fatty liver.

    BACKGROUND: Simvastatin is usually taken in the evening due to the circadian rhythm of hepatic cholesterol biosynthesis. The degree of reduction of low-density lipoprotein cholesterol (LDL-C) and the level of adherence to different administration time remained unknown in the Malaysian population. This study aims to investigate the effect of simvastatin on the percentage changes of lipid profile and the level of adherence to when simvastatin was instructed to be taken at different timing.

    METHODS: Nine primary care health clinics across Malaysia participated in this study. 147 statin-naive subjects were selected through convenient sampling and randomised into one of the three arms (after breakfast, after dinner or before bedtime). Differences on percentage reduction of LDL-C from baseline and level of adherence among the three groups at week-16 were compared. The main outcomes measured in this study were the percentage change of lipid parameters and the percentage of high-adherence (MMAS=8) at week-16.

    RESULTS: 59.2% of the patients were male. The mean age of the study population was 53.93± 10.85 years. Most of the patients were Malays (69.4%); followed by Indians (22.4%) and Chinese (8.2%). LDL-C decreased from 4.26 (Standard Deviation, SD1.01) to 2.36 (SD0.69)mmol/L at week-16 for patients taking simvastatin before bedtime; an absolute reduction of 44.95%.The differences of LDL-C percentage reduction between three arms were significantly different (p<0.001). The greatest LDL-C reduction was observed when simvastatin was taken before bedtime and revealed 56.2% patients with high-adherence at week-16.

    CONCLUSION: Simvastatin showed superior LDL-reduction and higher level of adherence when being instructed to be taken before bedtime.

    BACKGROUND: Inflammation process plays an important role in the development of atherosclerosis. Hypercholesterolemia is one of the major risk factors for atherosclerosis. The present study aimed to evaluate the effect of aqueous extract of Piper sarmentosum (P.s) on inflammatory markers like vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), and C-reactive protein (CRP).

    METHODS: Forty two male New Zealand white rabbits were divided equally into seven groups; (i) C- control group fed normal rabbit chow (ii) CH- cholesterol diet (1%cholesterol) (iii) X1- 1% cholesterol with water extract of P.s (62.5 mg/kg) (iv) X2- 1% cholesterol with water extract of P.s (125 mg/kg (v) X3- 1% cholesterol with water extract of P.s (250 mg/kg) (vi) X4- 1% cholesterol with water extract of P.s (500 mg/kg) and (vii) SMV group fed with 1% cholesterol supplemented with simvistatin drug (1.2 mg/kg). All animals were treated for 10 weeks. Blood serum was taken for observing the inflammatory markers at the beginning and end of the experiment.

    RESULTS: Rabbits fed with 1% cholesterol diet (CH) showed significant increase in the level of VCAM-1, ICAM-1 and CRP compared to the C group. The levels of VCAM-1, ICAM-1 and CRP in the 1% cholesterol group and supplemented with P.s (500 mg/kg) were significantly reduced compared to the cholesterol group. Similar results were also reported with simvistatin group.

    CONCLUSION: These results suggest that the supplementation of Piper sarmentosum extract could inhibit inflammatory markers which in turn could prevent atherosclerosis.

    This randomized, double-blind, placebo-controlled, and parallel-designed study was conducted to investigate the effect of a synbiotic product containing Lactobacillus gasseri [corrected] CHO-220 and inulin on lipid profiles of hypercholesterolemic men and women. Thirty-two hypercholesterolemic men and women with initial mean plasma cholesterol levels of 5.7±0.32 mmol/L were recruited for the 12-wk study. The subjects were randomly allocated to 2 groups; namely the treatment group (synbiotic product) and the control group (placebo), and each received 4 capsules of synbiotic or placebo daily. Our results showed that the mean body weight, energy, and nutrient intake of the subjects did not differ between the 2 groups over the study period. The supplementation of synbiotic reduced plasma total cholesterol and low-density lipoprotein (LDL)-cholesterol by 7.84 and 9.27%, respectively, compared with the control over 12 wk. Lipoproteins were subsequently subfractionated and characterized. The synbiotic supplementation resulted in a lower concentration of triglycerides in the very low, intermediate, low, and high-density lipoprotein particles compared with the control over 12 wk. The concentration of triglycerides in lipoproteins is positively correlated with an increased risk of atherosclerosis. Our results showed that the synbiotic might exhibit an atheropreventive characteristic. Cholesteryl ester (CE) in the high-density lipoprotein particles of the synbiotic group was also higher compared with the control, indicating greater transport of cholesterol in the form of CE to the liver for hydrolysis. This may have led to the reduced plasma total cholesterol level of the synbiotic group. The supplementation of synbiotic also reduced the concentration of CE in the LDL particles compared with the control, leading to the formation of smaller and denser particles that are more easily removed from blood. This supported the reduced LDL-cholesterol level of the synbiotic group compared with the control. Our present study showed that the synbiotic product improved plasma total- and LDL-cholesterol levels by modifying the interconnected pathways of lipid transporters. In addition, although Lactobacillus gasseri [corrected] CHO-220 could deconjugate bile, our results showed a statistically insignificant difference in the levels of conjugated, deconjugated, primary, and secondary bile acids between the synbiotic and control groups over 12 wk, indicating safety from bile-related toxicity.

    This randomized, double-blind, placebo-controlled, and parallel-design study was conducted to investigate the effect of a synbiotic product containing Lactobacillus gasseri [corrected] CHO-220 and inulin on the irregularity in shape of red blood cells (RBC) in hypercholesterolemic subjects. The subjects (n=32) were randomly allocated to 2 groups, a treatment group (synbiotic product) and a control group (placebo), and received 4 capsules of either synbiotic or placebo daily for 12 wk. Morphological representation via scanning electron microscopy showed that the occurrence of spur RBC was improved upon supplementation of the synbiotic. In addition, the supplementation of synbiotic reduced the cholesterol:phospholipids ratio of the RBC membrane by 47.02% over 12 wk, whereas the control showed insignificant changes. Our present study also showed that supplementation of the synbiotic reduced the concentration of saturated fatty acids (SFA), increased unsaturated fatty acids (UFA), and increased the ratio of UFA:SFA over 12 wk, whereas the control showed inconspicuous changes. The alteration of RBC membrane was assessed using fluorescence anisotropy (FAn) and fluorescence probes with different affinities for varying sections of the membrane phospholipid bilayer. A noticeable decrease in FAn of three fluorescent probes was observed in the synbiotic group compared with the control over 12 wk, indicative of increased membrane fluidity and reduced cholesterol enrichment in the RBC membrane.

    Kenaf is one of the important commercial fiber crops worldwide and defatted kenaf seed meal (DKSM) is a secondary by-product from the kenaf industry. Thus, efforts to turn this low-cost agricultural waste into value-added functional food ingredients will definitely bring advantageous impacts to the community health, environment and economy. The present study was aimed to investigate the cardioprotective properties of DKSM and its phenolics-saponins rich extract (PSRE) in diet-induced hypercholesterolemic rat model. Hypercholesterolemia was induced in Sprague-Dawley rats via atherogenic diet feeding and dietary interventions were conducted by incorporating DKSM (15% and 30%) and equivalent levels of PSRE (2.3% and 4.6%, respectively, equivalent to the total content of phenolics and saponins in DKSM groups) into the atherogenic diets. After 10 weeks of DKSM and PSRE supplementation, the hepatosomatic index, hepatosteatosis, serum lipid profile, Castelli risk indexes as well as hepatic and renal functions of hypercholesterolemic rats were significantly improved (p < 0.05). Besides, the levels of hepatic Hmgcr and serum Pcsk9 were lowered, along with transcriptional upregulations of hepatic Cyp7a1, Abca1, Lcat, ApoA2 and ApoE (p < 0.05). The gene expression of hepatic Ldlr was marginally enhanced by DKSM supplementation (p > 0.05), but superiorly upregulated by PSRE (p < 0.05). The combined results showed that hypercholesterolemia and the atherogenic risk in rats were effectively attenuated by DKSM and PSRE supplementation, possibly via modulations of multiple vital processes in hepatic cholesterol metabolism. Furthermore, phenolics and saponins may be the bioactives conferring DKSM and PSRE with their anti-hypercholesterolemic properties. In conclusion, DKSM and PSRE are prospective cardioprotective functional food ingredients for hypercholesterolemic individuals.

    Hypercholesterolemia causes endothelial dysfunction, an early feature of atherosclerosis, leading to increased production of adhesion molecules and cytokines. The aim of this study was to investigate the effects of three months of treatment with low dose atorvastatin on serum levels of adhesion molecules, interleukin-6 (IL-6) and highly sensitive C-reactive protein (hs-CRP) in patients with non-familial hypercholesterolemia. Fifty-five patients with non-familial hypercholesterolemia were randomized to treatment with atorvastatin 10 mg/day or placebo for 3 months. Soluble intercellular adhesion molecules-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), E-selectin, IL-6 and hs-CRP levels were measured to assess the inflammatory activity of the endothelium. There was a significant reduction in ICAM-1 at 2 weeks (p<0.0001) with further reduction at 3 months (p<0.0001). At 3 months, there were significant reductions in VCAM-1 (p<0.02), IL-6 (p<0.0001) and hs-CRP (p<0.01), but an increase in E-selectin levels (p<0.002). Treatment with statin was an independent determinant of change in ICAM-1 (p<0.05) and IL-6 levels (p<0.05) after correcting for anthropometric indices, blood pressure and lipid profile. Low-dose atorvastatin treatment leads to reduction in proinflammatory markers of endothelial function, suggesting an attenuation of endothelial activation and improvement in endothelial function, independent of lipid lowering. This may lead to a reduction in the progression of atherosclerosis.
