Objective This study examines the lipid profile change produced in response to tamoxifen (TAM) treatment, and its possible relationship with both apolipoprotein E genotype and menopausal state in patients with breast cancer. Methods: Blood samples were collected from 86 Spanish women with breast cancer before initiating TAM treatment and in the following 6, 12 and 18 months of treatment. Plasma lipid levels (total cholesterol, triglycerides, HDL-cholesterol and LDL-cholesterol) were determined using an automatic analyzer. Genotypes for apolipoprotein E (ApoE) were identified by PCR-RFLP using the HhaI enzyme. Results In all patients, significant reductions in total cholesterol and LDL-cholesterol concentrations and a significant increase in triglyceride concentrations were observed after 6, 12, and 18 months of TAM treatment compared to baseline (p<0.01 for each time point). In the subset of APOE4-negative patients, triglyceride concentrations also significantly increased after 6, 12, and 18 months of treatment (p=0.019, p=0.045, p=0.001, respectively), while APOE4-positive patients showed no significant lipid changes at 12 and 18 months. However, after 18 months of TAM treatment the overall triglyceride concentrations had risen by 24.75% in APOE4-negative patients vs 29.9% in APOE4-positive patients. In postmenopausal women, significant reductions in total cholesterol, LDL-cholesterol and LDL/HDL ratios were observed at each time point (p<0.020 for each). Conclusions TAM treatment induced similar plasma triglyceride increases in patients with positive or negative APOE genotype. Compared to premenopausal patients, postmenopausal breast cancer patients showed a more beneficial lipid profile change in response to treatment.

Genetic and nutritional factors interact together and modulate the plasma lipid profile. We identified variations in the gene encoding the liver X receptor α (LXRα) and investigated their effects on the plasma lipoprotein/lipid profile. We also examined whether the association between cholesterol intake and plasma lipid profile was modulated by LXRα variants. The LXRα gene was sequenced in thirty-five French-Canadian men with high plasma total cholesterol (>5·0 mmol/l) and LDL-cholesterol (>3·5 mmol/l) concentrations. Dietary cholesterol was obtained from a food-frequency questionnaire. The LXRα c.-115G>A, c.-840C>A and c.-1830T>C genotypes were determined by direct sequencing in 732 subjects. Molecular screening of the LXRα gene revealed sixteen variants. Genotypes c.-115G>A, c.-840C>A and c.-1830T>C (rare allele frequency of 14·3 %, 14·2 % and 11·0 %, respectively) were analysed further. Plasma total cholesterol concentrations were higher in carriers of the -115A, -840A and -1830C allele, compared with the -115G/G, -840C/C and -1830T/T homozygotes (P ≤ 0·05). In a model including the c.-115G>A polymorphism, cholesterol intake, the interaction term c.-115G>A × cholesterol intake (mg/d) and covariates, LXRα-115G>A explained 1·8 % and 2·1 % of the variance in total cholesterol and LDL-cholesterol concentrations (P = 0·02 andP = 0·01), whereas the interaction term explained 2·9 % (P = 0·002) and 2·8 % (P = 0·005), respectively. When subjects were divided into four groups according to the median of cholesterol (290·8 mg) and -115G>A genotypes, high cholesterol intake was associated with higher cholesterol levels in -115A carriers. Similar results were observed for c.-840C>A and c.-1830T>C. These results suggest that cholesterol intake interacts with LXRα variants to modulate the plasma lipid profile.

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.

Red dragon fruit (Hylocereus polyrhizus) peel contains anthocyanin, fiber and vitamin C, so it can be used to improve lipid profile in dyslipidemia. The peel of the dragon fruit is not durable, so in this study we used freeze-dried dragon fruit peel. The aim of this study was to prove that the administration of the red dragon fruit peel in a dose of 0.72 g/200 g BW, 1.08 g/200 g BW, and 1.44 g/200 g BW of rat per day for 28 days may improve lipid profile in male wistar strain white rats with high-fat diet. Lipid profiles were studied by examining of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. This was a pure experimental study using randomized post test only control group design. This study used experimental animal of 30 male wistar strain white rats which were divided into five groups. Measurements of total, LDL, and HDL cholesterol levels were done by CHOD-PAP method, while triglyceride level was measured with GPO-PAP method. Data were analyzed statistically by One Way Anova test. The results of this study indicated that giving the peel of red dragon fruit as much as 0.72 g lowered total cholesterol levels, 1.08 g lowered total and LDL cholesterol levels, and 1.44 g lowered total cholesterol, LDL cholesterol, triglyceride levels, and raised HDL cholesterol level. Red dragon fruit peel can be used alternatively to improve lipid profile in dyslipidemia.

In the present study we examined whether two virgin olive oils (VOO1 and VOO2), of the same variety (Olea europaeavar.hojiblanca) and with a similar composition of minor components but differing in the content of triacylglycerol molecular species, had different effects on blood pressure and plasma lipid levels in a healthy elderly population. Thirty-one participants, aged 84·9 (SD 6·4) years, were asked to participate in the study. No differences were found with regard to blood pressure after both experimental periods (VOO1 and VOO2). However, plasma total cholesterol and LDL-cholesterol were reduced only after VOO1 (P<0·01). The reduction of plasma cholesterol concentrations was related to the incorporation of oleic acid into plasma cholesteryl esters and phospholipids, which was higher after VOO1 (P<0·01). Indeed, the oleic acid concentration in cholesteryl esters and phospholipids strongly correlated with plasma total cholesterol and LDL-cholesterol levels in all experimental periods studied (r2>0·418,P<0·07), except for phospholipids in VOO1 (P=0·130 for total cholesterol andP=0·360 for LDL-cholesterol). These results have demonstrated that blood pressure and plasma lipids can be modified by the consumption of VOO in elderly people, but that the extent of such modification depends on the composition and amount of active minor components and triacylglycerol molecular species.

AbstractOn the basis of several preclinical and clinical studies, we have assumed that phytochemicals may play an important role in plasma lipid metabolism. The aim of this study was to evaluate the effects of dietary administered Chlorella pyrenoidosa, young barley and fruit peel polyphenols from Flavin7 on plasma lipid metabolism in breast cancer model in female rats. The phytopharmaceuticals were dietary administered at two different concentrations (0.3% and 3%). The administration of drugs lasted for the whole duration of the experiment (14-15 weeks) until autopsy. At the end of the experiments blood was collected from animals and serum lipid parameters were evaluated. Flavin7 in lower dose significantly decreased LDL-cholesterol and in higher dose significantly decreased triacylglycerol and VLDL-cholesterol levels. Chlorella at the higher dose significantly decreased LDL- and VLDL-cholesterol and triacylglycerol levels. Young barley significantly decreased LDL cholesterol (at the higher dose); on the other hand, a tendency of increased serum triacylglycerol and VLDLcholesterol levels was found (in both doses). Our results pointed to significant beneficial effects of fruit peel polyphenols from Flavin7 and C. pyrenoidosa on plasma lipid metabolism in female rats. Further research is needed to elucidate the health benefits of phytochemicals in whole foods.

To assess whether the type of fat ingested at breakfast can modify the plasma lipid profile and other cardiovascular risk variables in postmenopausal women at risk of cardiovascular disease, a longitudinal, randomized, and crossover study was carried out with postmenopausal women at risk of CVD. They were randomly assigned to eat each type of breakfast during one month: 6 study periods (breakfast with the same composition plus butter/margarine/virgin olive oil) separated by two washout periods. On the first and last days of each study period, weight, arterial blood pressure, heart rate, and body mass index were recorded in fasting conditions and a blood sample was collected to measure plasma lipid profile. When comparing final values to baseline values, we only found out statistically significant differences on plasma lipid profiles. Butter-based breakfast increased total cholesterol and HDL, while margarine-based breakfast decreased total cholesterol and LDL and increased HDL. After the olive oil-based breakfast intake, a tendency towards a decrease of total cholesterol and LDL levels and an increase of HDL levels was observed. No statistically significant differences were observed in triglycerides levels, BMI, and arterial pressure in any breakfast type. The margarine-based breakfast was the only one which significantly increased the percentage of volunteers with optimal lipid profiles. The polyunsaturated fat at breakfast has improved the plasma lipid profile in the analyzed sample population, suggesting that PUFA-based breakfast can be advisable in women at risk of CVD.

Postmenopausal women tend to have significant changes in lipid profile when compared with premenopausal women. Incidence of cardiovascular disease after menopause believed to occur due to changes in the plasma lipid levels. This study was conducted to estimate and compare serum levels of total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol (LDL-c) and high-density lipoprotein cholesterol (HDL-c) among Sudanese pre and postmenopausal women. 94 participant women were enrolled in this cross-sectional study. 47 post-menopause women age 48 - 70 years and 47 pre-menopause women age 25-47 years. Estimation of serum lipid profile was carried out using Biosystems colorimetric methods and results statistics were computed by using SPSS. A significant increase in total cholesterol(TC), triglyceride, and LDL-c with a significant decrease in (HDL-c) level among postmenopausal women where found, when compared with pre-menopause women (P-value= <0.05). Total cholesterol and LDL-C level were observed significantly increased according to three interval time duration of menopausal onset (p=0.009 and p=0.034). A positive correlation was observed between the age of and total cholesterol levels in postmenopausal women (R=0.463, P-value =0.001). Study results revealed that postmenopausal status was associated with substantial changes in lipid profile that considered risk factors for cardiovascular disease in Sudanese women.
