Hypocholesterolemic effect of spirulina in patients with hyperlipidemic nephrotic syndrome

In nephrotic syndrome, large amounts of plasma proteins are lost in urine, causing a decrease in the plasma oncotic pressure. This leads to enhanced hepatic synthesis of albumin and other proteins, including lipoproteins, causing a secondary hyperlipidemia. Essential fatty acids such as gamma-linolenic acid (GLA) can prevent accumulation of cholesterol in the body, and spirulina has an appreciable amount of GLA. In this study 23 patients (age 2 to 13 years) with nephrotic syndrome received either medication (group I) or medication plus 1 g/day Spirulina (group II). Height, weight, and serum levels of fasting blood sugar, triglycerides, total cholesterol (TC), and low- and high-density cholesterol fractions (LDL-C and HDL-C, respectively) were measured before and after the 2-month study period. Mean height and weight were normal compared with healthy, age-matched Indian children. Lipoprotein cholesterol levels were significantly increased at baseline. TC significantly decreased by 116.33 mg/dl, LDL-C by 94.14 mg/dl, and triglycerides by 67.72 mg/dl in group II; in control group I, these values fell by 69.87, 61.13, and 22.62 mg/dl, respectively. The LDL-C:HDL-C ratio also decreased significantly, by 1.66 in group II and 1.13 in group I. TC:HDL-C decreased by 1.96 in group II and 1.19 in group I. HDL-C:LDL-C also improved significantly in both the groups. It can be concluded that spray-dried Spirulina capsules, rich in antioxidants, GLA, amino acids, and fatty acids, helped reduce the increased levels of lipids in patients with hyperlipidemic nephrotic syndrome.     

Hypolipidemic Effect of Tomato Juice in Hamsters in High Cholesterol Diet-Induced Hyperlipidemia

Tomato is a globally famous food and contains several phytonutrients including lycopene, β-carotene, anthocyanin, and flavonoids. The increased temperature used to produce tomato juice, ketchup, tomato paste and canned tomato enhances the bioactive composition. We aimed to verify the beneficial effects of processed tomato juice from Kagome Ltd. (KOT) on hypolipidemic action in hamsters with hyperlipidemia induced by a 0.2% cholesterol and 10% lard diet (i.e., high-cholesterol diet (HCD)). Male Golden Syrian hamsters were randomly divided into two groups for treatment: normal (n = 8), standard diet (control); and experimental (n = 32), HCD. The 32 hamsters were further divided into four groups (n = 8 per group) to receive vehicle or KOT by oral gavage at 2787, 5573, or 13,934 mg/kg/day for six weeks, designated the HCD-1X, -2X and -5X groups, respectively. The efficacy and safety of KOT supplementation was evaluated by lipid profiles of serum, liver and feces and by clinical biochemistry and histopathology. HCD significantly increased serum levels of total cholesterol (TC), triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C), LDL-C/HDL-C ratio, hepatic and fetal TC and TG levels, and degree of fatty liver as compared with controls. KOT supplementation dose-dependently decreased serum TC, TG, LDL-C levels, LDL-C/HDL-C ratio, hepatic TC and TG levels, and fecal TG level. Our study provides experiment-based evidence to support that KOT may be useful in treating or preventing the onset of hyperlipidemia.     

Coaching patients with coronary heart disease to achieve the target cholesterol: a method to bridge the gap between evidence-based medicine and the "real world"--randomized controlled trial

Community studies have demonstrated suboptimal achievement of lipid targets in the management of patients with coronary heart disease (CHD). An effective strategy is required for the application of evidence-based prevention therapy for CHD. The objective of this study was to test coaching as a technique to assist patients in achieving the target cholesterol level of <4.5 mmol/L. Patients with established CHD (n = 245) underwent a stratified randomization by cardiac procedure (coronary artery bypass graft surgery or percutaneous coronary intervention) to receive either the coaching intervention (n = 121) or usual medical care (n = 124). The primary outcome measure was fasting serum total cholesterol (TC), serum triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and calculated low-density lipoprotein cholesterol (LDL-C) level, measured at 6 months post-randomization. At 6 months, the serum TC and LDL-C levels were significantly lower in the coaching intervention group (n = 107) than the usual care group (n = 112): mean TC (95%CI) 5.00 (4.82-5.17) mmol/L versus 5.54 (5.36-5.72) mmol/L (P <.0001); mean LDL-C (95%CI) 3.11 (2.94-3.29) mmol/L versus 3.57 (3.39-3.75) mmol/L (P <.0004), respectively. Coaching had no impact on TG or on HDL-C levels. Multivariate analysis showed that being coached (P <.001) had an effect of equal magnitude to being prescribed lipid-lowering drug therapy (P <.001). The effectiveness of the coaching intervention is best explained by both adherence to drug therapy and to dietary advice given. Coaching may be an appropriate method to reduce the treatment gap in applying evidence-based medicine to the "real world."     

Effects on serum lipids of adding instant oats to usual American diets.

This study was designed as a test of the serum lipid response and dietary adaptation to recommended daily inclusion of instant oats in an otherwise regular diet. Hypercholesterolemic adults were randomly assigned to a control or intervention group. Participants in the intervention group were given packages of instant oats and requested to eat two servings per day (approximately two ounces dry weight), substituting the oats for other carbohydrate foods in order to maintain baseline calorie intake and keep weight stable. Serum lipids were measured in blood collected by venipuncture at baseline, four weeks, and eight weeks. Baseline mean total cholesterol (TC) levels were 6.56 mmol/L and 6.39 mmol/L for intervention and control groups, respectively. After eight weeks, mean serum total cholesterol of the intervention group was lower by -0.40 mmol/L, and mean net difference in TC between the two groups was 0.32 mmol/L (95% CI: 0.09, 0.54). Low-density lipoprotein-cholesterol was similarly reduced with mean net difference of 0.25 mmol/L (95% CI: 0.02, 0.48) between the two groups. Mean soluble fiber intake increased along with slight self-imposed reductions in mean total fat, saturated fat, and dietary cholesterol intake in the intervention group. Neither group changed mean body weight. Daily inclusion of two ounces of oats appeared to facilitate reduction of serum total cholesterol and LDL-C in these hyperlipidemic individuals.

Serum fatty acid composition in primary school children is associated with serum cholesterol levels and dietary fat intake

OBJECTIVE: To examine the serum fatty acid composition, serum cholesterol levels, and dietary fat intake associated with body composition in primary school children of both urban and rural regions in Taiwan. DESIGN: Subjects were randomly stratified by region and primary school. The sample consisted of 870 children aged 10 and 11 y old. The sample was equally distributed between an urban region (Kaohsiung City) and a rural region (Yunlin County). The gender ratio of samples from each area was matched. Food record-assisted 24-h dietary recalls and serum lipid measurements were collected for each child, and associations between serum total cholesterol (TC) and fatty acids composition as well as between body mass index (BMI) and triceps skinfold (TSF) were evaluated for both urban and rural regions. RESULTS: Compared with students in the urban region, those in the rural region had significantly lower total fat intake, BMI, TSF, TC, and LDL cholesterol (LDL-C) and higher HDL-cholesterol (HDL-C) (P<0.05). Increased total fat (P<0.05) as a proportion of total energy was associated with increased TC and LDL-C. Lauric, myristic, and oleic acid levels in the serum of urban boys were significantly higher (P=0.0001, 0.0003, and 0.0398, respectively) than those of rural boys. In girls, the different fatty acid compositions affected TC concentrations, and palmitic and stearic acids of serum in the high-TC group were significantly lower (P=0.0179 and 0.0001, respectively) than those in the low-TC group. CONCLUSIONS: Urban children had a dietary fat intake that both quantitatively and qualitatively differed from the traditional rural Chinese diet in Taiwan as reflected in rural children. Consumption of total fat was positively associated with BMI, TSF, TC, and LDL-C levels in Taiwanese children aged 10 and 11 y. SPONSORSHIP: This study was partly sponsored by a research grant from the Department of Health, Taiwan, ROC.

Influence of fish consumption on the distribution of serum cholesterol in lipoprotein fractions: comparative study among fish-consuming and non-fish-consuming populations

The objective of this study was to investigate serum lipoprotein levels in order to assess cardiovascular disease (CVD) risk factors between fish-consuming populations and non-fish-consuming populations, as it has been speculated that fish intake reduces CVD risk. A representative sample of one thousand subjects (529 men and 471 women) were selected, with ages ranging from 20 to 70 years, from 40 villages belonging to fish-consuming (500) or non-fish-consuming (500) populations. Serum lipoprotein lipids such as total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were analysed biochemically using standard procedures. The ratios of TC: HDL-C and LDL-C: HDL-C were computed. Mean values of serum LDL-C and the ratios of LDL-C: HDL-C and TC: HDL-C were significantly lower and HDL-C levels were higher in fish-consumers than in non-fish-consumers. The concentrations of HDL-C decreased with increasing age, while the reverse was true for LDL-C and for the LDL-C: HDL-C and TC: HDL-C ratios. There were significant sex differences for certain age groups in both of the population groups. The 5th, 50th and 95th percentile cut-off values for these parameters were lower in fish-consumers than in non-fish-consumers. The prevalence of individuals at risk of CVD because of low HDL-C (<35 mg/dL), high LDL-C (>130 mg/dL) and their atherogenic ratios (LDL-C: HDL-C >3.5 and TC: HDL-C>4.5) was significantly greater in non-fish-consumers. This study highlights that the fish-consuming population had a lower atherogenic risk than the non-fish-consuming population. The intake of fish may have substantial implications for public health and health economy by decreasing the risk of CVD. However, more studies are warranted to better define the mechanisms of cardioprotection by dietary fish and fish oils.
