Background: Atherosclerosis (AT) is a chronic inflammatory process in which oxidative stress is the key event. Amaranth oil (AmO) has potential hypolipidemic and antiatherogenic effects. The aim of the study was to compare the effects of AmO and rapeseed oil (RaO) supplementation on expression of early markers of AT and lipid profile in obese or overweight subjects. Methods: A randomized, double-blinded cross-over study was conducted, in which participants took 20 mL of AmO in the first arm and 20 mL RaO in the second arm, switching after the washout period. Serum concentrations of adhesion molecules (sP-selectin, sVCAM-1), high-sensitivity C-reactive protein (hsCRP), asymmetric dimethylarginine (ADMA), and lipid profile were assessed before and after nutritional interventions. In addition, anthropometric parameters were measured. Results: The total (TC) and low-density lipoprotein (LDL) cholesterol concentrations increased significantly in the AmO group in comparison with RaO (ΔTC 5.52 ± 35 vs. −8.43 ± 17.65 mg/dL; p = 0.002 and 4.43 ± 34.96 vs. −7.55 ± 16.41 mg/dL; p = 0.002, respectively). There were no significant differences in other parameters analyzed between the groups. Conclusion: The use of AmO instead of RaO may increase cardiovascular risk in obese and overweight subjects.

It is well known that rapeseed oil improves lipid profile and has antiatherosclerotic properties. Recently, amaranth oil has also become popular due to its potential health benefits. However, the effect of this oil on atherosclerosis markers in humans is not clear. Therefore, this study aimed to compare the effect of amaranth and rapeseed oils on selected atherosclerosis-related parameters in overweight and obese subjects. In this randomized cross-over study, 44 subjects were instructed to consume 20 mL of amaranth oil and rapeseed oil during two consecutive three-week intervention periods separated by a washout period of the same duration as the intervention. The outcome variables included changes in tumor necrosis factor-alpha, adiponectin, oxidized low-density lipoprotein, apolipoproteins (Apo) A1, B and E as well as glucose and insulin homeostasis markers. Compared to rapeseed oil, amaranth oil had a slight positive effect on adiponectin levels (mean (95% confidence interval): 0.55 (0.22–0.89) vs. -0.29 (−0.75–0.16), p = 0.0002) but negatively affected ApoB concentrations (0.05 (−0.01–0.11) vs. 0.03 (−0.07–0.00), p = 0.0004) and ApoB/A1 ratio (0.01 (−0.03–0.05) vs. −0.02 (−0.04–0.00), p = 0.0113). No differences between the other analyzed parameters were observed. In conclusion, amaranth oil does not have a greater beneficial effect on atherosclerosis markers than rapeseed oil. However, further studies with a longer intervention period are needed. The study was retrospectively registered with the German Clinical Trials Register within the number: DRKS00014046, date of registration: 3 May 2018.

Background: Cholesterol-lowering nutraceuticals are useful in the management of moderate hypercholesterolemia. Methods: In a parallel-group, randomized, placebo-controlled double-blind trial we evaluated the effects on plasma total cholesterol, low-density lipoprotein cholesterol (LDL-c), and inflammatory biomarkers of a nutraceutical combination (Aquilea Colesterol®) containing phytosterols (1.5 g), red yeast rice providing monacolin K (10 mg), hydroxytyrosol (5 mg), and plasma cholesterol values >5.17 mmol/L (>200 mg/dL) and LDL-c >2.97 mmol/L (>115 mg/dL). At baseline and at one and three months we recorded dietary habits; anthropometric parameters; blood pressure; lipid profile; fasting glucose; liver, renal, and muscle function tests, C-reactive protein (hs-CRP); and interleukin-6. Results: 13 men and 27 women (mean age 61.8 years) completed the trial; 20 participants received the nutraceutical and 20 received placebo. No adverse effects were noted. Compared to placebo, at one and three months the nutraceutical reduced total cholesterol by 11.4% and 14.1%, LDL-c by 19.8% and 19.7%, and apolipoprotein B by 12.4% and 13.5%, respectively (p < 0.001; all). hs-CRP decreased significantly (p = 0.021) in the nutraceutical group. Conclusion: The nutraceutical Aquilea Colesterol® is useful for reducing total cholesterol, LDL-c, and inflammation in individuals with moderate hypercholesterolemia.

ABSTRACT Introduction Obesity is emerging as an epidemic worldwide. Obesity is associated with a number of comorbid conditions, such as diabetes mellitus, hypertension, cancer, dyslipidemia, cardiovascular abnormalities, anemia, obstructive sleep apnea, and psychosocial abnormalities. Aim This study aims at comparing the lipid profile levels of obese and nonobese men. Materials and methods This was a case—control study conducted at a tertiary care center. Totally, 80 men in the age group of 20 to 47 years attending the master health checkup were included in the study, out of which 40 men with normal body mass index (BMI) of 18 to 25 belonged to group I and 40 men with increased BMI of 30 and above belonged to group II. Lipid profile parameters, such as triglycerides (TGLs), total cholesterol, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol were estimated in them. The data were statistically analyzed using Statistical Package for the Social Sciences (SPSS) software version 15.0. Results Statistically significant difference was found in the total cholesterol levels with a p-value of 0.040 while the difference in LDL cholesterol was statistically highly significant with a p-value of 0.040. Conclusion Among lipid profile parameters, only total cholesterol and LDL cholesterol showed significant difference between the obese and nonobese individuals. However, the other parameters like HDL cholesterol and TGLs did not show any significant difference. How to cite this article Babu SV, Jagadeesan AR, Ramalingam J.

AbstractBackground:Excess weight, unhealthy lifestyle habits and their sequelae have become a well-recognized public health problem in most countries. The objective of the study was to examine the relationship of adolescent overweight/obesity with behavioral habits and their association with blood pressure (BP) and lipid profile.Methods:Anthropometric parameters, lifestyle, BP and lipid profile of 736 adolescents were evaluated cross-sectionally. The classifications of normal weight, overweight and obese were based on BMI z-scores.Results:About 42.1% of adolescents were overweight/obese, 11.3% were smokers, 33.2% consumed alcohol and 34% reported low activity. Males began smoking earlier, consumed alcohol more often, exercised less and spent more screen time than females. Alcohol consumption was more prevalent among smokers and was associated with higher BP and dyslipidemia. Smokers exercised less intensely and had lower high density lipoprotein-cholesterol (HDL-C) than non-smokers. Obesity was a risk factor for higher BP and dyslipidemia. Longer screen time was associated with higher triglycerides, while intense physical activity with lower systolic BP.Conclusions:Obesity is related to an adverse lipid and BP profile during adolescence. Clustering of hazardous habits was observed, which is known to aggravate the cardiovascular risk.

The aim of the study was to compare the effect of the administration of a mixture of fibres on body weight-loss, satiety, lipid profile and glucose metabolism. We included 200 overweight or obese patients in a parallel, double-blind, placebo-controlled clinical trial, who were randomised to receive, in the context of an energy-restricted diet for a period of 16 weeks, a mixed fibre dose (3 gPlantago ovatahusk and 1 g glucomannan) twice (b.i.d. group) or three times daily (t.i.d. group) or placebo. Weight change was the primary efficacy endpoint. Satiety, dietary compliance, lipid profile, glucose tolerance, insulin resistance and high-sensitivity C-reactive protein were secondary endpoints. Weight loss tended to be higher after both doses of fibre ( − 4·52 (sd0·56) and − 4·60 (sd0·55) kg) than placebo ( − 0·79 (sd0·58) kg); the differences in changes between groups were not statistically significant. Postprandial satiety increased in both fibre groups compared to the placebo. The differences between groups in LDL-cholesterol levels were significant (P = 0·03), with greater reductions in the two fibre-supplemented groups ( − 0·38 (sd0·10) and − 0·24 (sd0·09) mmol/l in the b.i.d. and t.i.d. groupsv.− 0·06 (sd0·09) mmol/l in placebo group). A similar pattern was observed for changes in total cholesterol:HDL-cholesterol and HDL-cholesterol:LDL-cholesterol ratios. Interventions were well tolerated and had no effects on HDL-cholesterol, glucose and insulin concentrations, glucose tolerance or high-sensitivity C-reactive protein. In conclusion, a 16-week dietary supplement of soluble fibre in overweight or obese patients was well tolerated, induced satiety and had beneficial effects on some CVD risk factors, the most important of which was a significant decrease in plasma LDL-cholesterol concentrations.

Abstract Context: Polycystic ovary syndrome (PCOS) is associated with a higher frequency of cardiovascular risk factors. Apolipoprotein (apo) A-I and apoB are potent markers for cardiovascular risk. Data on apo levels in women with PCOS are scarce and contradictory. Objective: Our objective was to identify changes in lipid metabolism in women with PCOS, and the relative impact of obesity, insulin resistance, and hyperandrogenism on lipid parameters. Design: This was a case-control study. Setting: The study was performed at a single referral center. Subjects: PCOS was diagnosed according to the 2003 Rotterdam criteria. Healthy mothers with regular menstrual cycles served as controls. Main Outcome Parameters: Fasting insulin, triglycerides (TGs), cholesterol, high-density lipoprotein (HDL)-cholesterol, apoA-I, and apoB were determined. Low-density lipoprotein (LDL)-cholesterol was calculated using the Friedewald formula. Results: We included 557 women with PCOS and 295 controls. After correction for age and body mass index, PCOS women had higher median levels of insulin (10.1 vs. 6.9 mU/liter), TGs (95 vs. 81 mg/dl), cholesterol (196 vs. 178 mg/dl), and LDL-cholesterol (125 vs. 106 mg/dl) in combination with lower levels of HDL-cholesterol (46 vs. 55 mg/dl) and apoA-I (118 vs. 146 mg/dl) compared with controls (all P values ≤ 0.01). apoB levels were similar in cases and controls. Free androgen index, body mass index, SHBG, and estradiol were independent predictors of apoA-I levels in women with PCOS. Conclusions: PCOS is associated with a more pronounced atherogenic lipid profile. Furthermore, obesity and hyperandrogenism contribute to an adverse lipid profile. Finally, PCOS seems to constitute an additional risk factor for an atherogenic lipid profile.

Background: Studies on the cholesterol lowering activity of tocotrienols have yielded mixed results, with some showing cholesterol lowering effect while some showing no activity.Aim: A randomized, double-blind, parallel group study was conducted to investigate the cholesterol lowering activity of tocotrienols. Methods: Thirty-two hypercholesterolemic subjects were randomly assigned to orally receive either 300 mg of mixed tocotrienols capsules daily or placebo capsules containing 300 mg of soya bean oil for a period of 6 months. The subjects were monitored before supplementation and monthly thereafter for their serum cholesterol as well as tocotrienol and tocopherol concentrations.Results: The serum total cholesterol and low density lipoprotein (LDL) cholesterol of the subjects in the tocotrienol supplementation group were decreased significantly by -8.9 ± 0.9% and -12.8 ± 2.6% respectively after 4 months of supplementation and the reduction persisted till the end of the 6-month study, with a reduction of -10.8 ± 1.0% and  -17.3 ± 1.8%, respectively from baseline. Moreover, there was a 22-fold increase in the total tocotrienol concentrations from baseline during supplementation compared to the placebo group, while the concentration of α-tocopherol recorded only a modest increase. On the other hand, the serum cholesterol, total tocotrienol and α-tocopherol concentrations of subjects in the placebo group remained essentially unchanged.Conclusions: Supplementation with mixed tocotrienols at dose of 300 mg per day resulted in the lowering of the serum total and LDL cholesterol levels after 5 months of supplementation.Keywords: tocotrienols, cholesterol-lowering, total cholesterol, LDL cholesterol, tocopherols

Postmenopausal women are at higher risk of developing cardiovascular diseases due to changes in lipid profile and body fat, among others. The aim of this study was to evaluate the association of urinary tartaric acid, a biomarker of wine consumption, with anthropometric (weight, waist circumference, body mass index (BMI), and waist-to-height ratio), blood pressure, and biochemical variables (blood glucose and lipid profile) that may be affected during the menopausal transition. This sub-study of the PREDIMED (Prevención con Dieta Mediterránea) trial included a sample of 230 women aged 60–80 years with high cardiovascular risk at baseline. Urine samples were diluted and filtered, and tartaric acid was analyzed by liquid chromatography coupled to electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS). Correlations between tartaric acid and the study variables were adjusted for age, education level, smoking status, physical activity, BMI, cholesterol-lowering, antihypertensive, and insulin treatment, total energy intake, and consumption of fruits, vegetables, and raisins. A strong association was observed between wine consumption and urinary tartaric acid (0.01 μg/mg (95% confidence interval (CI): 0.01, 0.01), p-value < 0.001). Total and low-density lipoprotein (LDL) cholesterol were inversely correlated with urinary tartaric acid (−3.13 μg/mg (−5.54, −0.71), p-value = 0.016 and −3.03 μg/mg (−5.62, −0.42), p-value = 0.027, respectively), whereas other biochemical and anthropometric variables were unrelated. The results suggest that wine consumption may have a positive effect on cardiovascular health in postmenopausal women, underpinning its nutraceutical properties.

IntroductionPositive regulatory domain containing 16 (PRDM16) protein represents the key regulator of brown adipose tissue (BAT) development. It induces brown fat phenotype and represses white adipose tissue specific genes through the association with C-terminal binding co-repressor proteins (CtBP1 and CtBP2). In healthy adults presence of BAT has been associated with lower glucose, total cholesterol and LDL (low-density lipoprotein) cholesterol levels. Our aim was to analyze the association of PRDM16 gene (rs12409277) and CtBP2 gene (rs1561589) polymorphisms with body mass index (BMI), fasting glucose level and lipid profile of adolescents.Material and methodsOur study included 295 healthy school children, 145 boys (49.2%) and 150 girls (50.8%), 15 years of age. Genotypes for the selected polymorphisms were detected by the real-time PCR method. Age, gender, height, weight, lipid profile (total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides) and fasting glucose levels were recorded.ResultsWe did not find a statistically significant association of rs12409277 and rs1561589 polymorphisms with BMI, fasting glucose and lipid profile of adolescents. We further analyzed the combined effect of the two SNPs and the statistical analysis showed that carriers of CT genotype of rs12409277 polymorphism and GG genotype of rs1561589 polymorphism had significantly lower total cholesterol (p = 0.001) and LDL cholesterol (p = 0.008) levels compared to all other groups of genotypes.ConclusionsOur study suggests that rs12409277 and rs1561589 polymorphism might have an influence on total and LDL cholesterol levels in adolescents. Larger studies should be performed in order to confirm our results.

Objectives: Glycated hemoglobin (HbA1c) is the most commonly used glycemic index among diabetic patients. The present study sought to investigate the relationship between HbA1c and lipid parameters among healthy pregnancies and gestational diabetic cases. Materials and Methods: Seventy-five Saudi pregnant women within the age group of 19 to 43 years were selected for this crosssectional study. The participants were categorized into with and without gestational diabetes (GDM), all of whom were non-smokers; in addition, they neither had a previous history of chronic illnesses nor were they on any medications which could alter lipid profile and HbA1c concentrations. Totally, 75 g of oral glucose tolerance test (OGTT) was utilized to identify 25 women with GDM. All biochemical tests including HbA1c, fasting blood sugar (FBG), total cholesterol (TC), low-density lipoprotein (LDL-cholesterol), triglycerides (TG), and high-density lipoprotein (HDL-cholesterol) were performed by a biochemical auto-analyzer. The collected data were statistically analyzed using a paired student’s t test. The P values of <0.05 were considered statistically significant on all the analyses related to healthy pregnancies and those associated with GDM. Results: The HbA1c and FBG values demonstrated significant correlation with GDM (P<0.001 each). However, TC, LDL-cholesterol, and TG failed to indicate any significant difference between the 2 groups. Conversely, HDL-cholesterol and the ratio of TG and HDLcholesterol revealed remarkable differences between GDM and healthy participants (P<0.05 each). Conclusions: In general, the blood levels of glucose, HbA1c, TG, and HDL-cholesterol are of paramount significance in GDM. Predictably, HbA1c can be employed as one of the markers in evaluating the risk factors in developing dyslipidemia among pregnant women.
