Clinical trials have shown that soya protein reduces the concentrations of some atherogenic lipids in subjects with normal renal function. The present study examined the effects of soya protein on serum lipid concentrations and lipoprotein metabolism in patients on hypercholesterolaemic haemodialysis. Twenty-six hypercholesterolaemic (total cholesterol ≥6·21mmol/l) patients on haemodialysis were studied in a randomized, double-blind, placebo-controlled clinical trial. After a 4-week run-in phase, the subjects were randomly assigned to two groups. Isolated soya protein or milk protein 30g was consumed daily as a beverage at breakfast or post-dialysis for 12 weeks. Soya protein substitution resulted in significant reductions in total cholesterol (17·2 (sd8·9)%), LDL-cholesterol (15·3 (sd12·5)), apo B (14·6 (sd12·1)%) and insulin (23·8 (sd18·7)%) concentrations. There were no significant changes in HDL-cholesterol or apo A-I. These results indicate that replacing part of the daily protein intake with soya protein has a beneficial effect on atherogenic lipids and favourably affects lipoprotein metabolism in hypercholesterolaemic patients undergoing haemodialysis.

The Influence of Chronic Helicobacter Pylori Infection on some Serum Lipid Profile Parameters, Apolipoproteins A-I and B and Lp(a) Lipoprotein Data on proatherogenic lipid profile alterations due to chronic Helicobacter pylori (HP) infection are contradictory. Aim of this study was to examine the differences in some lipid parameters between 55 subjects of both gender with a chronic HP infection (IgG>50 U/mL and IgA <20 U/mL) and 55 gender matched HP seronegative subjects (IgG and IgA <20 U/mL). Total cholesterol (TC) (p<0.001), triglycerides (TG) (p<0.05), LDL-cholesterol (LDL-C) (p<0.02), non-HDL-cholesterol (non-HDL-C), apolipoprotein (apo) B (p<0.001), Lp(a) and HDL-cholesterol (HDL-C) serum levels were higher in HP seropositive than in seronegative subjects, while there were almost no differences in apo A-I. In HP seropositive subjects, the frequency of pathological TC (p<0.001), TG (p<0.05), LDL-C (p<0.01), non-HDL-C (p<0.01), apo B (p<0.02) and Lp(a) serum levels was higher compared to seronegative. Serum HP IgG titers correlated negatively with TC, LDL-C (p<0.05), non-HDL-C, apo B and Lp(a) levels, and positively with TG, HDL-C and apo A-I levels. Results are similar for both genders. Our results confirm the hypothesis that a chronic HP infection could modify the lipid profile in a proatherogenic way.

AbstractThis study evaluated the effects of Mg administration on carotid intima–media thickness (CIMT), glycaemic control and markers of cardio-metabolic risk in diabetic haemodialysis (HD) patients. This randomised, double-blind, placebo-controlled clinical trial was conducted in fifty-four diabetic HD patients. Participants were randomly divided into two groups to take either 250 mg/d Mg as magnesium oxide (n27) or placebo (n27) for 24 weeks. Mg supplementation resulted in a significant reduction in mean (P<0·001) and maximum levels of left CIMT (P=0·02) and mean levels of right CIMT (P=0·004) compared with the placebo. In addition, taking Mg supplements significantly reduced serum insulin levels (β=–9·42 pmol/l; 95% CI –14·94, –3·90;P=0·001), homoeostasis model of assessment-insulin resistance (β=–0·56; 95 % CI –0·89, –0·24;P=0·001) and HbA1c (β=–0·74 %; 95 % CI –1·10, –0·39;P<0·001) and significantly increased the quantitative insulin sensitivity check index (β=0·008; 95 % CI 0·002, 0·01;P=0·002) compared with the placebo. In addition, Mg administration led to a significant reduction in serum total cholesterol (β=–0·30 mmol/l; 95% CI –0·56, –0·04;P=0·02), LDL-cholesterol (β=–0·29 mmol/l; 95% CI –0·52, –0·05;P=0·01), high-sensitivity C-reactive protein (hs-CRP) (P<0·001) and plasma malondialdehyde (MDA) (P=0·04) and a significant rise in plasma total antioxidant capacity (TAC) levels (P<0·001) compared with the placebo. Overall, we found that taking Mg for 24 weeks by diabetic HD patients significantly improved mean and maximum levels of left and mean levels of right CIMT, insulin metabolism, HbA1c, total cholesterol and LDL-cholesterol, hs-CRP, TAC and MDA levels.

Background. Abnormal lipid profile is an important risk factor in the development of macrovascular atherosclerotic complications in patients with type 2 diabetes mellitus (T2D). Factors that contribute to endothelial cell dysfunction associated with the initiation of atherosclerosis include oxidative stress. The aim of this study was to investigate the relationship between lipid profile and oxidative stress in type 2 diabetics with and without ischemic heart disease (IHD). Methods. We studied 80 patients with T2D, 40 with IHD (group A1) and 40 without IHD (group A2). We also studied 51 non-diabetics, 31 with IHD (group B1), and 20 without IHD (group B2 - control group). Lipid profile was estimated by the total cholesterol, HDL cholesterol, LDL cholesterol, the level of triglyceride (Tg), lipoproteina a (Lp a), Apo A I, A II, B 100 and E. To evaluate the oxidative status we measured circulating oxidized LDL (ox LDL), erythrocyte antioxidative enzyme activity: superoxide dismutase (E-SOD), glutathione peroxidase (E-GPX), as well as the total antioxidative serum activity (TAS). Inflammatory reaction was estimated by C-reactive protein (CRP) and fibrinogen. Results. No significant difference was found in the lipid profile in groups A1, A2 and B1, but the group B2 had the lowest one. Lp a level was significantly higher in group B1 comparing to other groups (p < 0.05). There was no significant difference in the level of ox LDL between the groups. In diabetics, ox LDL positively correlated with the total cholesterol, LDL cholesterol, non HDL cholesterol, Apo B 100 and the relations between LDL/HDL and Tg/HDL (p < 0.001), as well as with Tg and fibrinogen (p < 0.05). In group B1, ox LDL positively correlated with total cholesterol, Tg (p < 0.01), LDL, and non HDL cholesterol (p < 0.05) and significantly with Apo B 100 (p < 0.001). There was no significant difference in the antioxidant enzyme activities between the groups of diabetics (A1 and A2), but fibrinogen was higher in the group with IHD (group A1, p < 0.05). Group B1 had lower ESOD activity than the groups A1 and A2 (p < 0.05), but CRP was higher (p < 0.05). There were no significant correlations between oxLDL and CRP in groups A1 and A2, but it was statistically significant in the group B1 (p < 0.05). Conclusion. In this study we demonstrated the increased oxidative stress in diabetics compared to non-diabetics regardless of the presence of IHD. Fibrinogen, but not CRP, was higher in diabetics with IHD, compared to diabetics without IHD. The increased oxidative stress, the reduced antioxidative activity E-SOD, and the higher level of CRP were found in non-diabetics with IHD compared to non-diabetics without IHD.

A prospective study was conducted in the Northern region of Bangladesh, to investigate the serum lipid profile viz the level of total cholesterol (TC), Triglyceride (TG), HDL-cholesterol and LDL-cholesterol of hypertensive patients and compares them with levels of control subjects. The results revealed that serum total cholesterol, triglyceride and LDL-cholesterol were significantly markedly raised (p>0.001) whereas the level of HDL-cholesterol was significantly lower (p>0.001) in hypertensive patients as compared to control subjects. No significant changes of serum lipid profile were found between male and female hypertensive patients, but in control subjects, markedly higher levels of serum lipid profile was observed in male compared to that of female. It was concluded that hypercholesterolaemia, hypertrigyceridaemia and low density lipoprotein are the main lipid abnormalities on the incidence of hypertension in the study area. Key words: Hypertension, Total cholesterol (TC), triglyceride (TG), HDL- cholesterol and LDL-cholesterol. J. bio-sci. 14: 93-98, 2006

Soya protein has well-documented beneficial effects on serum lipid levels in adults, the potential beneficial effect of a prolonged soya protein-substituted diet in children and adolescents with familial (FH) and polygenic hypercholesterolaemia (PH) being unknown. To assess the effect of 3 months’ treatment of children and adolescents with FH and PH with a soya-substituted diet on serum lipids and lipoproteins, twenty-three children and adolescents were initially assigned to a standard phase 1 diet for 3 months, after which they were instructed to include soya protein (0·25–0·5 g/kg body weight) into their diet for 3 months. Sixteen patients (ten males and six females, thirteen with FH (eight males and five females), three with PH (two males and one female); mean age 8·8 (sd 4·2) years (range 4–18 years); mean BMI 16·7 (sd 2·6) kg/m2)) completed both phases. The phase 1 diet resulted in a significant reduction of total cholesterol (TC), LDL-cholesterol and apo B by 12·3, 11·8 and 10·6 %, respectively, HDL-cholesterol, TAG, apo A1 and lipoprotein(a) not being different. Dietary intake of soya protein during phase 2 resulted in a significant decrease of TC, LDL-cholesterol and apo B by 7·7, 6·4, and 12·6 %, respectively. TAG, HDL-cholesterol, apo A1, and lipoprotein(a) did not change significantly. Substitution of soya protein for animal protein in a low-fat, fat-modified diet is of additional benefit in many, but not all, children and adolescents with FH and PH when aiming at lowering serum TC, LDL and apo B. It seems to be a feasible long-term dietary lifestyle intervention and may grant additive benefit in the prevention of early vascular disease.

Abstract Context Vitamin D deficiency is highly prevalent across the world. The existing evidence suggests vitamin D may have beneficial effects on serum lipid profiles and thus cardiovascular health. Objective The objective of this systematic review and meta-analysis was to examine the effect of vitamin D supplementation on serum lipid profiles. Data Source Original randomized controlled trials (RCTs) examining the effect of vitamin D supplementation on serum lipid profiles and published before July 2018 were identified by searching online databases, including PubMed, Google Scholar, and ScienceDirect, using a combination of relevant keywords. Data Extraction Data on study characteristics, effect size, measure of variation, type of vitamin D supplementation, and duration of follow-up were extracted by the author. Data Analysis PRISMA guidelines for systematic reviews were followed. Random effects (DerSimonian and Laird [D-V)] models were used to pool standardized mean differences in total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides between the active and the placebo arms of RCT studies. Between-study heterogeneities were assessed using Cochrane Q and I2, and publication bias was assessed using Begg’s test, Egger’s test, and funnel plot. Results A total of 41 RCTs comprising 3434 participants (n = 1699 in the vitamin D supplementation arm and n = 1735 in the placebo arm) were identified and included in the meta-analysis. Approximately 63.4% of study participants were women, with 14 studies conducted entirely among women. Approximately 24% of the trials had follow-up duration >6 months, whereas the remaining 76% had follow-up duration of <6 months. The standardized mean differences (SMDs) and 95% confidence intervals (CIs) for comparing the change from baseline to follow-up between the vitamin D supplementation arm and the placebo (control) arm were as follows: total cholesterol = –0.17 (–0.28 to –0.06); LDL cholesterol = –0.12 (–0.23 to –0.01); triglycerides = –0.12 (–0.25 to 0.01); and HDL cholesterol = –0.19 (–0.44 to 0.06). After removing a trial that was an outlier based on the magnitude of the effect size, the SMD for triglycerides was –0.15 (–0.24 to –0.06) and that for HDL cholesterol was –0.10 (–0.28 to 0.09). The improvements in total cholesterol and triglycerides were more pronounced in participants with baseline vitamin D deficiency. Conclusions Vitamin D supplementation appeared to have a beneficial effect on reducing serum total cholesterol, LDL cholesterol, and triglyceride levels but not HDL cholesterol levels. Vitamin D supplementation may be useful in hypercholesterolemia patients with vitamin D insufficiency who are at high risk of cardiovascular diseases.

Introduction and Aim: Serum lipids play a pivotal role in the immune response of the host during dengue. The aim of this study was to evaluate the serum lipid abnormalities in dengue patients and to study the relationship between serum lipids with disease severity and platelet count.   Materials and Methods: This case control study was carried out in 75 cases of dengue of age group > 18 years divided into three groups namely dengue without warning symptoms (DNWS), dengue with warning symptoms (DWWS) and severe dengue (SD) and 75 age and gender matched healthy controls. Lipid parameters such as total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides were thereafter measured in all the subjects.   Results: Among 75 patients with dengue fever, 52 (69.4%) were classified as DNWS, 15 (20%) as DWWS and the remaining 8 (10.6%) as SD. Lower levels of serum total cholesterol (TC) levels (118.8 + 30.71) (p <0.0001) were observed among patients with DNWS when compared to controls. A strong significant positive correlation was seen between the platelets and serum HDL cholesterol levels among the subjects with SD (r = 0.712, p=.047*) and weak negative correlation was observed between the platelets and triglycerides in patients with dengue with warning signs (r = -0.275, p=.048*).   Conclusion: We observed a strong association of diminished TC, HDL and LDL cholesterol levels with the severity of dengue. Based on our findings, these three lipid parameters could be utilized as a simple laboratory tool to identify dengue severity in resource limited settings.

Excess consumption of egg especially its yolk has been implicated in hyperlipidaemia (high level of cholesterol and triglyceride in the blood). Conversely, soluble dietary fibers, probably due to their ability to bind free lipid molecules, appear to play an important role in protecting against hyperlipidaemia. This study sought to evaluate the comparative effects of selected sources of fibers: apple, oats, and wheat bran, on serum lipid profile in physiologically normal Wistar rats. Twenty rats were used for the study and were randomized into four groups, with each containing five animals (). A group which serves as control was fed with egg yolk while the other three groups were fed with apple, oats, and wheat bran, respectively. After two weeks of feeding, the animals were fasted overnight and blood samples from the retro-orbital sinus of the eye were collected for analyses of lipid profile. The results obtained showed that the group fed with oats had the lowest level of total cholesterol ( mg), low density lipoprotein (LDL) cholesterol ( mg), and triglycerides (TG) ( mg), as well as the highest level of HDL cholesterol ( mg). On the contrary, the group fed with egg yolk showed the highest level of total cholesterol ( mg), LDL cholesterol ( mg), and triacylglyceride ( mg), as well as the lowest level of HDL cholesterol ( mg). There was no significant difference () between oats and apple in their effects on blood lipid profile of Wistar rats. Wheat bran, being an insoluble dietary fibre, had less significant () effect on the blood lipid profile when compared to oats and apple. Findings from this study may assist physicians and dieticians in recommending appropriate diet for individuals desiring to normalize their blood lipids levels.

Phytosterols and red yeast rice are largely studied cholesterol-lowering nutraceuticals, respectively inhibiting the bowel absorption and liver synthesis of cholesterol. Our aim was to test the effect of combined nutraceutical-containing phytosterols and red yeast rice vs. a placebo on the lipid profile. We performed a parallel arms, double-blind, placebo-controlled clinical trial, randomizing 88 moderately hypercholesterolemic subjects to treatment with a combined nutraceutical containing phytosterols (800 mg) and red yeast rice, standardized to contain 5 mg of monacolins from Monascus purpureus, with added niacin (27 mg) and policosanols (10 mg) (LEVELIP DUO®), or placebo. The mean LDL-Cholesterol (LDL-C) change at Week 8 was −32.5 ± 30.2 mg/dL (−19.8%) in the combined nutraceutical group and 2.5 ± 19.4 mg/dL (2.3%) in the placebo group. The estimated between-group difference of −39.2 mg/dL (95% CI: −48.6; −29.8) indicates a statistically significant difference between treatments in favor of the combined nutraceutical (p < 0.0001). Total Cholesterol (TC), non-HDL cholesterol (non-HDL-C), Apolipoprotein B, TC/HDL-C and LDL-C/HDL-C improved in a similar way in the combined nutraceutical group only. No significant changes in other clinical and laboratory parameters were observed. In conclusion, the tested combined nutraceutical was well tolerated, while significantly reducing the plasma levels of LDL-C, TC, non-HDL-C, ApoB, TC/HDL-C and LDL-C/HDL-C ratios in mildly hypercholesterolemic patients. Trial registration (ClinicalTrials.gov): NCT03739242.

Importance: Sleep duration has been considered as a risk factor for cardiometabolic disease and mortality. Several studies suggest that sleep duration can influence the serum lipid levels, but the association remains unclear. Objective: The aim of present study is to assess the association of sleep duration with serum lipid levels in an elderly Korean population. Methods: The KURE study is a cohort study to investigate risk factors for major disorders of the elderly. This cross-sectional analysis was conducted among 926 participants (302 men and 624 women aged 64-87 years) who completed baseline health examination in 2012. Sleep duration was measured by the interviewer-assisted questionnaire. Habitual sleep time was calculated based on the response to the questions about hour of bedtime, hour of rising, and hours of nap during the passing year. Total cholesterol, triglyceride and high density lipoprotein (HDL) cholesterol concentrations in serum were measured from overnight fasting blood samples. Low density lipoprotein (LDL) cholesterol was calculated from total cholesterol, HDL cholesterol and triglyceride levels using Friedewald’s formula. Multiple linear regression models were conducted to examine whether sleep duration was associated with serum lipid levels. Results: Sleep duration was not significantly associated with total cholesterol (β=-0.154mg/dL per sleep hour, p =0.843), triglyceride (β=-1.000, p =0.506) and LDL cholesterol (β=0.678, p =0.339) after adjusting for age, sex, body mass index, systolic blood pressure, tobacco smoking, alcohol intake, physical activity, diabetes mellitus, myocardial infarction and stroke. However sleep duration was inversely associated with HDL cholesterol (β=-0.644, p =0.015) in fully adjusted model. In the sex-specific analysis, sleep duration was marginally associated with HDL cholesterol in men (β=-0.770, p =0.078) and significantly associated with HDL cholesterol in women (β=-0.685, p =0.037) after fully adjustment. Conclusions: Our findings suggest that longer sleep duration was associated with lower serum HDL cholesterol level in an elderly Korean population. Keywords: Sleep duration, lipids, HDL cholesterol, elderly
