BackgroundThe aim of this study was to investigate the status of serum lipids during endocrine therapy.MethodsWe retrospectively analysed lipid profiles during the 5-year treatment of 1487 consecutive postoperative BC patients. Lipid parameters included triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL-C) and high-density lipoprotein (HDL-C). Those biomarkers were measured at baseline and 1, 2, 3, 4 and 5 years following the initiation of endocrine therapy.ResultsFor premenopausal BC patients, LDL levels rapidly decreased at 1 year in the tamoxifen (TAM) group compared with baseline levels (p<0.05), and this decline remained for the following 4 years. Additionally, LDL levels were significantly lower in the TAM group than in the nonendocrine group at all assessment time points (p<0.05). Similarly, TC levels also decreased in the TAM group compared with baseline levels at all assessment time points (p<0.05), and compared with the levels in the nonendocrine group, TC levels were also lower for the first 4 years. For postmenopausal BC patients, there was no significant difference in the lipid profiles (TG, TC, LDL and HDL) in the letrozole (LET), anastrozole (ANA) or exemestane (EXE) groups compared with the nonendocrine group. For patients who received TAM, compared with the nonendocrine group, TC levels decreased at 1 year, and LDL levels decreased at 1 and 2 years.ConclusionsTAM may improve LDL and TC levels in premenopausal BC patients. In postmenopausal BC patients, aromatase inhibitors (AIs) may have no adverse effects on lipid profiles, and TAM may have limited beneficial effects on serum lipids.

Abstract Background The aim of this study was to investigate the effects of different exercise loads (short, medium and long swimming distances) on the thyroid hormone (THs) levels and serum lipid profiles of male professional swimmers. Materials and methods The participants in this study were 20 healthy male professional swimmers aged 18–22 years, who all competed at an elite level. The THs levels [thyroid-stimulating hormone (TSH), triiodothyronine (T3) and thyroxine (T4)] and serum lipid profile were also obtained. Results It was determined that the TSH and T4 values increased after exercise (p < 0.05). When compared to the pretest values, the increase in the TSH and T4 values following the L400 tests was statistically significant (p < 0.001 and p < 0.05). It was also determined that the changes in the cholesterol, high-density lipoprotein (HDL) and total glucose (TG) values were significant after exercise (p < 0.001). There was no significant difference between the groups in terms of the low-density lipoprotein (LDL) values (p = 0.07). According to the results, the cholesterol counts for the M200 and L400 groups were lower than the pretest counts (p < 0.001). When compared to the pretest values, the decrease in the HDL counts for the M200 and L400 groups was higher than the pretest HDL counts (p < 0.001 and p < 0.05, respectively). Further, the triglycerides counts for the M200 and L400 groups were higher than the pretest counts (p < 0.001). Conclusions Different exercise loads can have a positive impact on the physical health of swimmers via their lipid profiles and THs. Additionally, swimming exercise could be considered an efficient protective strategy against metabolic disorders, as it serves to balance the serum lipid levels.

ABSTRACT BACKGROUND: The interaction between serum lipids and C virus infection is well known, as are serum lipid levels in the Peg-IFN / RBV-based treatment. However, with direct action antivirals (DAAs) this behavior is still unclear. OBJECTIVE: To compare serum lipids levels between patients treated with Peg-IFN/RBV and DAAs and to evaluate lipids in sustained virological response (SVR) with DAAs. METHODS: Retro prospective study comparing the behavior of total cholesterol (TC), low-density lipoprotein (LDL) and triglycerides (TG) serum levels during treatment with DAAs (G-DAAs) and a control historic group Peg-IFN/RBV (G-PR). Coorte, prospective study, to study the behavior of lipids in the SVR with DAAs. Data were collected at the beginning of treatment (baseline: t-base) and at week 12 of treatment (t-12) for G-DAAs and at week 24 (t-24) for G-PR, groups. In the cohort evaluation, the samples at t-base and at week 12 after the end of treatment (t-SVR). Delta lipids: difference between lipids in t-12 / t-24 minus t-base for comparison between G-PR and G-AADs groups and t-SVR minus t-base for lipid analysis in SVR. Analysis with Kruskal Wallis and Wilcoxon tests to compare the delta lipids of the groups. The P value was 0.05. RESULTS: In the assessment between G-PR and G-DAAs groups, we included 63 and 121 patients, respectively. The groups did not differ one from the other (BMI, sex, genotype, fibrosis, total cholesterol, LDL, and TG) except by age (50.38±10.44 vs 56±9.69, P=0.0006). We observed a decrease in levels of TC and LDL and an increase in TG, in G-PR, and in G-DAAs the opposite (Δ TC -13.9±34.5 vs 4.12±34.3 P=0.0005, Δ LDL -7.16±32 vs 10.13±29.92, P=0.003, Δ TG 4.51±53.7 vs -8.24±49.93, P=0.0025). In the coorte analysis, we included 102 patients, 70% men and 56% F4, 95 of them reached SVR. We observed an increase of TC and LDL and a decrease of TG in both groups (SVR and non SVR), with no statistical difference (Δ TC P=0.68; Δ LDL P=0.69; Δ TG P=0.43). We did not find significant difference in delta evaluation by genotype 1 and 3 (Δ TC +29.7±40.2 vs +13.4±30.3, P=0.06; Δ LDL +21.4±28.6 vs +16.6±31.3, P=0.41; Δ TG -3.6±60.6 vs -0.7±40, P=0.91). CONCLUSION: Serum lipids level differed during treatment with Peg-IFN and DAAs. Treatment with DAAs was associated with an increase of TC and LDL and a decrease of TG, independently of SVR.

AbstractThe aim of the work was to investigate the correlation between serum TSH (thyrotropin) levels within normal range and serum lipids. A total of 1962 subjects with normal thyroid function were enrolled. The subjects were divided into four groups according to the quartiles of serum normal TSH levels, [Q1 (0.27–1.68) mIU/l, Q2 (1.69–2.35) mIU/l, Q3 (2.36–3.07) mIU/l, and Q4 (3.08–4.20) mIU/l]. The effect of serum normal TSH levels on serum lipid profiles of different age or gender was analyzed. The total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) levels of the Q3 group and TG levels of the Q4 group were higher than those of the Q1 group in youth (p <0.05). The TC levels of the Q3 group were higher than those of the Q2 group in middle age (p <0.05). The LDL-C levels of middle age or elderly were higher than those of youth at the same TSH levels (p <0.05), while the TC levels of middle age were higher than those of youth in Q1, Q3, or Q4 group (p <0.05), and the TC and HDL-C levels of elderly were higher than those of youth in the Q2 group (p <0.05). The TG levels of the Q3 group were higher than those of Q1 group in males (p <0.05). The LDL-C levels of the Q3 group were higher than those of the Q1 group in females (p <0.05). In conclusion, the normal serum TSH levels were found to be closely related to serum lipid profiles, and with increasing TSH levels, serum lipids levels increased gradually.

ABSTRACT Background: Researchers have reported association of plasma/serum lipids and lipoproteins with different cancers. Increase levels of circulating lipids and lipoproteins have been associated with breast cancer risk. Aim: The aim of this study is to compare serum lipid profiles: total-cholesterol (T-CHOL), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) and very low density lipoprotein-cholesterol (VLDL-C) between breast cancer patients and normal participants. Materials and Methods: A total of 403 women in this study were divided into two groups in the period during May 2006-April 2007. Blood samples were collected from 249 patients with early stage breast cancer and 154 normal controls for serum lipid profiles (T-CHOL, TG, HDL-C, LDL-C and VLDL-C) analysis using Hitachi 717 Autoanalyzer (Roche Diagnostic GmbH, Germany). TG, LDL-C and VLDL-C levels in breast cancer group were significantly increased as compared with normal controls group (P < 0.001), whereas HDL-C and T-CHOL levels were not. Results: The results of this study suggest that increased serum lipid profiles may associate with breast cancer risk in Thai women. Further studies to group important factors including, cancer stages, types of cancer, parity, and menopausal status that may affect to lipid profiles in breast cancer patients along with an investigation of new lipid profiles to clarify most lipid factors that may involve in breast cancer development are needed.

Background: Meaningful underestimation of low-density lipoprotein (LDL) cholesterol is an important shortcoming of Friedewald’s formula (FF) at higher triglyceride (TG) levels. Recently a regression equation (RE) has been developed using lipid profiles in one setting and validated externally for the calculation of LDL cholesterol. This newly developed RE requires more studies in different settings.Objective: The aim of this study was to evaluate the performance of the regression equation against direct measurement.Materials and Methods: Lipid profiles of 600 subjects attending a tertiary healthcare center were included in this study. Specimens were collected and lipid profiles were measured by standard methods. Sixty two lipid profiles with TG above 400 mg/dL were excluded. Calculated LDL cholesterol values using FF and RE were compared with measured LDL cholesterol by Pearson’s correlation test, Passing & Bablok regression, accuracy within ±5% and ±12% of measured LDL cholesterol and two-tailed paired t test at various TG ranges.Results: The mean value of LDL cholesterol was 148.6 ± 37.2 mg/dL for direct measurement, 146.9 ± 42.4 mg/dL for FF and 148.6 ± 34.7 mg/dL for RE. The correlation coefficients of calculated LDL cholesterol values with measured LDL cholesterol were 0.949 (p<0.001) for FF and 0.959 (p<0.001) for RE. Passing & Bablok regression equation against measured LDL cholesterol was y = 0.897x + 16.2 for FF and y = 1.0842x – 13.1 for RE. Accuracy within ±5% of measured LDL cholesterol was 45% for FF, 57% for RE and within ±12% of measured LDL cholesterol was 84% for FF, 93% for RE. When calculated LDL cholesterol was compared with measured LDL cholesterol at different TG ranges, FF significantly underestimated LDL cholesterol at TG concentrations above 200 mg/dL whereas no significant difference was observed for RE.Conclusion: This study reveals that RE equation has similar performance to direct measurement for calculation of LDL cholesterolJ Enam Med Col 2015; 5(2): 75-79

AbstractDyslipidemia is one of the main risk factors for coronary heart disease (CHD). The E3 ubiquitin ligase which is encoded by the ring finger protein 145 (RNF145) gene is very important in the mediation of cholesterol synthesis and effectively treats hypercholesterolemia. Thus, the purpose of the present research is to investigate the connection between the polymorphism of the RNF145 gene and cholesterol levels in the populations in Xinjiang, China. A total of 1396 participants (Male: 628, Female: 768) were included in this study for genetic analysis of RNF145 gene, and we used the modified multiple connection detection response (iMLDR) technology to label two SNPs (rs17056583, rs12188266) of RNF145 genotyping. The relationship between the genotypes and the lipid profiles was analyzed with general linear model analysis after adjusting confounding variables. Through the analysis of the two SNPs in RNF145 gene, we discovered that both rs17056583 and rs12188266 were related to total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) concentrations (All P < 0.001). In addition, the association of rs17056583 and rs12188266 with lipid profiles concentrations is still statistically significant after multivariate adjustment of sex, age, smoking, obesity, drinking, diabetes, hypertension and lipid profiles. Meanwhile, we also found that rs17056583 was associated with high triglycerides concentrations before and after adjustment (All P < 0.001). Our study shows that both rs17056583 and rs12188266 SNPs of RNP145 gene are related to TC and LDL-C concentrations in Xinjiang population.

Abstract Recent efforts for alternative non-pharmaceutical treatments for postmenopausal osteoporosis are focused on nutritional measures. The aim of this study was to investigate the effect of table olive wastewater extract (OE) administration on bone mineral density (BMD) and biomechanical strength in ovariectomized rats. Thirty mature 9-month-old female Wistar rats were separated into 3 groups of ten; Control, Ovariectomized (OVX) and OVX+OE. BMD was measured before ovariectomy, 3 and 6 months afterwards. At the end of the study, blood, both femurs and tibias, internal organs and abdominal fat were collected. After three months, the percentage changes from baseline of the total and proximal tibial BMD of the OVX+OE group were both higher compared to the OVX group (p<0.005). Similar results were found after six months, when the percentage changes from baseline of the total and proximal tibial BMD of the OVX+OE group were both higher compared to the OVX group (p<0.005). Biomechanical testing of the femurs did not reveal any statistically significant difference between the groups. Body weights throughout the study, organs’ and abdominal fat ratios to final body weight, blood results (alanine aminotransferase; ALT, Gamma-glutamyltransferase; γ-GT, total cholesterol, high-density lipoprotein; HDL-cholesterol, low-density lipoprotein; LDL-cholesterol, calcium, phosphorus) were within normal limits and did not show any significant difference between the treated and untreated groups. As a conclusion, the administration of table olive wastewater extract for 6 months protected tibial BMD loss in comparison to the untreated OVX group without causing adverse effects.

Objective: Hyperlipidemia is one of the risk factors that contribute to the prevalence of coronary heart diseases and antihyperlipidemic agents, such as statin, was used to treat hyperlipidemia as a current therapy. Boesenbergia pandurata has not been exploited for antihyperlipidemic effect. Hence, this study aims to screen for the antihyperlipidemic activity of methanolic extracts of B. pandurata rhizomes (BPR extracts) in hypercholesterolemia-induced Sprague-Dawley rats.Methods: BPR extracts were prepared using the maceration method with 1500 ml of 80% methanol at room temperature for about 7 days. A toxicity study was carried out based on OECD guidelines. Hypercholesterolemia was induced by 6% lard oil, 2% of cheese, and egg yolks. Two different doses of BPR extracts, 200 and 400 mg/kg, were used to screen for antihyperlipidemic effect. Histopathological study was carried out in the liver. The results were evaluated for the statistically significant difference by using the one-way ANOVA followed by post hoc Dunnett test.Results: No mortality was witnessed even till 2 g/kg. Only 400 mg/kg of BPR extracts statistically reduced in total cholesterol (p<0.05), low-density lipoprotein-cholesterol (p<0.05) and an increase in high-density lipoprotein-cholesterol (p<0.05) when compared to the positive control. BPR extracts (400 mg/kg) showed less enlargement of lipid droplets as compared to positive control.Conclusion: BPR extracts can be a promising medicinal plant for treating hyperlipidemia in underdeveloped countries.
