Euglena gracilis (Euglena) is a microalgae found in most freshwater environments that produces paramylon, an insoluble β-1,3-glucan linked to human immunity. We hypothesized that Euglena powder has effects on immune function in apparently healthy adults. The study included male or female volunteers between the ages of 20 and 70 years who had white blood cell counts ranging from 4 × 103/µL to 10 × 103/µL, a "severe" rating on the stress questionnaire from the Korea National Health and Nutrition Examination Survey, and at least 2 upper respiratory infections with cold-like symptoms in the previous year. Participants received either a placebo or 700 mg of Euglena powder daily for 8 weeks. The study measured natural killer cell activity, cytokine concentrations, and blood lipid profiles to confirm the immune effect of Euglena consumption. In conclusion, Euglena improved immunological function through natural killer cell activity. Safety assessment showed no significant changes in vital signs or clinical chemistry indicators, and there were no adverse events associated with Euglena consumption. Euglena supplementation may help boost the immune systems of healthy individuals. Euglena gracilis is a freshwater microalgae that produces paramylon, which benefits human immunity. This study examined the effects of Euglena on immune function in apparently healthy subjects. Participants received either a placebo or 700 mg of Euglena powder daily for 8 weeks. Results showed improved immune function through natural killer (NK) cell activity, with no adverse events or safety concerns. Euglena supplementation may enhance the immune systems of apparently healthy individuals. [Display omitted] [ABSTRACT FROM AUTHOR]

• In familial dysbetalipoproteinemia (FD), evolocumab reduced non-HDL-C by 49%. • Non-HDL-C treatment goals were achieved by 89% of patients using evolocumab. • Evolocumab likely results in CVD reduction in FD. Familial dysbetalipoproteinemia (FD) is the second most common monogenic lipid disorder (prevalence 1 in 850-3500), characterized by postprandial remnant accumulation and associated with increased cardiovascular disease (CVD) risk. Many FD patients do not achieve non-HDL-C treatment goals, indicating the need for additional lipid-lowering treatment options. To evaluate the effect of the PCSK9 monoclonal antibody evolocumab added to standard lipid-lowering therapy on fasting and post fat load lipids and lipoproteins in patients with FD. A randomized placebo-controlled double-blind crossover trial comparing evolocumab (140 mg subcutaneous every 2 weeks) with placebo during two 12-week treatment periods. At the start and end of each treatment period patients received an oral fat load. The primary endpoint was the 8-hour post fat load non-HDL-C area under the curve (AUC). Secondary endpoints included fasting and post fat load lipids and lipoproteins. In total, 28 patients completed the study. Mean age was 62±9 years and 93% had an Ɛ2Ɛ2 genotype. Evolocumab reduced the 8-hour post fat load non-HDL-C AUC with 49% (95%CI 42-55) and apolipoprotein B (apoB) AUC with 47% (95%CI 41-53). Other fasting and absolute post fat load lipids and lipoproteins including triglycerides and remnant-cholesterol were also significantly reduced by evolocumab. However, evolocumab did not have significant effects on the rise above fasting levels that occurred after consumption of the oral fat load. Evolocumab added to standard lipid-lowering therapy significantly reduced fasting and absolute post fat load concentrations of non-HDL-C, apoB and other atherogenic lipids and lipoproteins in FD patients. The clinically significant decrease in lipids and lipoproteins can be expected to translate into a reduction in CVD risk in these high-risk patients. [Display omitted] [ABSTRACT FROM AUTHOR]

Background: In previous study, we found that coenzyme Q10 (CoQ10) improved glucolipid profile in dyslipidemic individuals, but the mechanism is not yet clear. Adipokines have been demonstrated to be vital targets of metabolic diseases. The hypothesis that adipokines mediate the association of CoQ10 on glucolipid metabolism needs to be further studied in human. Methods: In this randomized, double-blinded, placebo-controlled trial, 101 dyslipidemic individuals were administrated to 120 mg CoQ10 or placebo for 24 weeks. Anthropometric parameters, glucolipid profile, serum total adiponectin, leptin, and resistin were evaluated at baseline, week 12 and week 24. Results: CoQ10 treatment significantly increased serum adiponectin levels at week 12 (165 [0, 362] ng/mL, p < 0.001) and at week 24 (523 [0, 1056] ng/mL, p < 0.001]), which was significant different compared with placebo (p < 0.001). The increase of adiponectin was negative associated with decrease in index of homeostasis model assessment of insulin resistance (HOMA-IR, r = − 0.465, p = 0.001), triglyceride (TG, r = − 0.297, p = 0.047), and low-density lipoprotein cholesterol (LDL-c, r = − 0.440, p = 0.002) at week 24 only in CoQ10-treated group. Resistin was reduced by CoQ10 only at week 24 (− 1.19 [− 4.35, 0.00] ng/mL, p < 0.001), which was significant different compared with placebo (p < 0.001). Reduction of resistin was positively correlated with the change in HOMA-IR (r = 0.343, p = 0.021) and TG (r = 0.323, p = 0.030) at week 24 in CoQ10-treated group but not placebo group. Leptin was not influenced by CoQ10 treatment. Mediation analysis indicated that the improvement of HOMA-IR, TG and LDL-c by CoQ10 was mediated by adiponectin but not resistin. Conclusions: Our study shows that CoQ10 ameliorates glucolipid profile and adipokines dysfunction in dyslipidemic patients in 24 weeks' intervention. The beneficial effect of CoQ10 on glucolipid profile was mediated by adiponectin. Trial registration: ClinicalTrials.gov, NCT02407548.

Deep seawater (DSW) has been investigated for its lipid-lowering effects, but clinical evidence is still far from conclusive. Therefore, this study was conducted to examine the effects of refined DSW (RDSW) on hypercholesterolemia. In this randomized, double-blind, placebo-controlled trial, 78 Korean participants were randomized to either an RDSW group that drank RDSW for 8 weeks or a placebo group. Clinical laboratory information was collected from all subjects at 0, 4, and 8 weeks. Both groups showed a significant reduction in total cholesterol (TC), whereas only the RDSW group demonstrated a significant decrease in low-density lipoprotein cholesterol (LDL-c) during the study. Stratified analysis of both groups revealed a significant reduction of TC in the moderately high TC subgroup. However, only the RDSW exhibited a significant decline of LDL-c in the high LDL-c subgroup. In addition, lipoprotein(a) decreased significantly in the RDSW group, but not in the placebo. RDSW did not affect other lipid profiles, including high-density lipoprotein cholesterol (HDL-c), triglyceride, free fatty acid, apolipoproteins, and other markers including inflammation marker, hematological parameters, blood and urine chemistry, and vital signs. RDSW improved lipid profiles by decreasing TC and LDL-c while maintaining HDL-c levels in people with hypercholesterolemia. [ABSTRACT FROM AUTHOR]

Objective: to evaluate the effectiveness of ginge (Zingiber officinale) in reducing blood sugar and lipid levels in people with type 2 diabetes. Method: a randomized and double-blind clinical trial conducted with people with type 2 diabetes in primary care facilities. The study included individuals aged between 20 and 80 years old, using oral antidiabetic drugs and with HbA1c levels between 6.0% and 10%. The participants were paired 1:1, allocated in two distinct groups, and randomized in blocks, based on their HbA1c levels. In the experimental group, the participants used 1.2g of ginger and, in the control group, 1.2g of placebo, daily for 90 days. The primary outcome was a reduction in fasting blood sugar and HbA1c, and the secondary outcome was a reduction in lipids and HOMA-IR. 103 individuals completed the study, 47 in the experimental group and 56 in the control group. Results: the participants in the experimental group showed a greater reduction in the blood glucose and total cholesterol values compared to the control group. Conclusion: the use of ginger can help in the treatment of people with diabetes, and data support the inclusion of this herbal drug in the clinical practice of nurses.

Background: Hypertriglyceridemia is associated with increased cardiovascular risk and may be caused by impaired lipoprotein clearance. Angiopoietin-like protein 3 (ANGPTL3) inhibits lipoprotein lipase activity, increasing triglycerides and other lipids. Evinacumab, an ANGPTL3 inhibitor, reduced triglycerides in healthy human volunteers and in homozygous familial hypercholesterolemic individuals. Results from 2 Phase 1 studies in hypertriglyceridemic subjects are reported here.Methods: Subjects with triglycerides >150 but ≤450 mg/dL and low-density lipoprotein cholesterol ≥100 mg/dL (n=83 for single ascending dose study [SAD]; n=56 for multiple ascending dose study [MAD]) were randomized 3:1 to evinacumab:placebo. SAD subjects received evinacumab subcutaneously at 75/150/250 mg, or intravenously at 5/10/20 mg/kg, monitored up to day 126. MAD subjects received evinacumab subcutaneously at 150/300/450 mg once weekly, 300/450 mg every 2 weeks, or intravenously at 20 mg/kg once every 4 weeks up to day 56 with 6 months of follow-up. The primary outcomes were incidence and severity of treatment-emergent adverse events. Efficacy analyses included changes in triglycerides and other lipids over time.Results: In the SAD, 32 (51.6%) versus 9 (42.9%) subjects on evinacumab versus placebo reported treatment-emergent adverse events. In the MAD, 21 (67.7%) versus 9 (75.0%) subjects on subcutaneously evinacumab versus placebo and 6 (85.7%) versus 1 (50.0%) on intravenously evinacumab versus placebo reported treatment-emergent adverse events. No serious treatment-emergent adverse events or events leading to death or treatment discontinuation were reported. Elevations in alanine aminotransferase (7 [11.3%] SAD), aspartate aminotransferase (4 [6.5%] SAD), and creatinine phosphokinase (2 [3.2%) SAD, 1 [14.3%] MAD) were observed with evinacumab (none in the placebo groups), which were single elevations and were not dose-related. Dose-dependent reductions in triglycerides were observed in both studies, with maximum reduction of 76.9% at day 3 with 10 mg/kg intravenously (P<0.0001) in the SAD and of 83.1% at day 2 with 20 mg/kg intravenously once every 4 weeks (P=0.0003) in the MAD. Significant reductions in other lipids were observed with most evinacumab doses versus placebo.Conclusion: Evinacumab was well-tolerated in 2 Phase 1 studies. Lipid changes in hypertriglyceridemic subjects were similar to those observed with ANGPTL3 loss-of-function mutations. Because the latter is associated with reduced cardiovascular risk, ANGPTL3 inhibition may improve clinical outcomes.Clinical Trial Registration: https://www.clinicaltrials.gov.

Background: Regular cocoa consumption has been shown to reduce blood pressure, improve lipid profiles, and increase insulin sensitivity and flow-mediated dilatation in healthy adults. It is assumed that these effects can be attributed to polyphenolic cocoa ingredients such as flavanols, especially to (--)-epicatechin.Nutritive intervention studies to prove this hypothesis are scarce. Objective: We aimed to evaluate whether regular consumption of 25 mg of pure (--)-epicatechin can affect increased cardiometabolic risk factors [blood pressure, glucose and lipid metabolism, lowdensity lipoprotein (LDL) oxidation] in overweight-to-obese subjects. Design: Forty-eight overweight or obese nonsmokers [body mass index (kg/m²) ≥25.0, ages 20--65 y] with clear signs of metabolic syndrome (blood pressure ≥130/85 mm Hg, glucose >5.55 mmol/L, or triglycerides >1.69 mmol/L or cholesterol >5.2 mmol/L in fasting blood) and without chronic diseases were included in a randomized, placebo-controlled, double-blind crossover study. Participants ingested daily 25 mg (--)-epicatechin (encapsulated) or placebo for 2-wk in random order (2-wk washout). After an overnight fast, blood pressure was monitored and blood samples were collected before and after both treatments. Anthropometric data were determined at each visit. Dietary intake was assessed by 3-d food records during both treatments and during run-in and washout phase. Results: Supplementation of pure (--)-epicatechin did not signifi- cantly affect blood pressure, glucose, insulin, homeostasis model assessment of insulin resistance, triglycerides, or total, LDL, or HDL cholesterol. Oxidized LDL, vitamins C and E, and β-carotene in plasma were not modulated. Body weight, fat mass, fat distribution, and the intake of energy, nutrients, and (--)-epicatechin from food remained stable throughout the study. Conclusions: Daily intake of 25 mg of pure (--)-epicatechin for 2 wk does not reduce cardiometabolic risk factors in overweight-to-obese adults. Thus, the hypothesis that the cardioprotective effects of regular cocoa consumption are exclusively ascribed to (--)-epicatechin should be reconsidered. The study was registered at the German Clinical Trial Register as DRKS-ID: DRKS00009846. [ABSTRACT FROM AUTHOR]

Background: Respiratory syncytial virus (RSV) is an important cause of illness in older adults. This study assessed efficacy of a vaccine for prevention of RSV-associated acute respiratory illness (ARI), defined by specified symptoms with virologic confirmation.Methods: This phase 2b study evaluated RSV postfusion F protein (120 µg) with glucopyranosyl lipid adjuvant (5 µg) in 2% stable emulsion. Subjects aged ≥60 years were randomly assigned at a ratio of 1:1 to receive vaccine or placebo (all received inactivated influenza vaccine). Ill subjects recorded symptoms and provided blood and nasal swab samples.Results: In the per-protocol population (n = 1894), the incidence of RSV-associated ARI occurring ≥14 days after dosing was 1.7% and 1.6% in the vaccine and placebo groups, respectively, for a vaccine efficacy (VE) of -7.1% (90% confidence interval [CI], -106.9%-44.3%). Efficacy was not observed in secondary analyses that included seroresponse to nonvaccine RSV antigens (VE, 8.9%; 90% CI, -28.5%-35.4%) or symptoms combined with seroresponse (VE, 10.0%; 90% CI, -45.4%-44.4%). On day 29, 92.9% of vaccinees had an anti-F immunoglobulin G antibody seroresponse. Overall, 48.5% and 30.9% of RSV vaccine recipients reported local and systemic solicited symptoms, respectively.Conclusion: The RSV vaccine was immunogenic but did not protect older adults from RSV illness.Clinical Trials Registration: NCT02508194.

Background: Research published to date on the relationship between insulin resistance (IR) and fructose consumption is scarce, has used different methods, and has yielded sometimes contradictory results. This study aims to determine whether a low-fructose and/or low-sucrose diet supervised by a physician or nurse decreases IR compared to a standard diet.Methods/design: This field trial is located at primary care centers. The participants are adults aged 29 to 66 years, with a Body mass Index (BMI) between 29 and 40.99 kg/m2 and without diabetes. To date, 245 participants have been assigned randomly to the low-fructose diet intervention group (LFDI) at health centers in the western health service zone of Tenerife island, and 245 to the standard-diet control group (SDC) at health centers in the eastern health service zone. Recruitment is opportunistic and is carried out by physicians and nurses at participating health centers. Initially (baseline), and after 24 weeks of intervention, dietary records, physical activity, waist circumference, BMI, blood pressure, fasting blood glucose and insulin concentrations (HOMA2-IR) and lipid profile are recorded; blood glucose and insulin and lipid profile are also recorded 2 h after a 75-g glucose overload. After 48 weeks (24 weeks after the intervention), fasting blood samples are again obtained and a physical examination is performed. All tests and measures are repeated and recorded except dietary records, physical activity and oral glucose overload. Low-fructose diets are designed by calculating free and total (free + fructose associated with sucrose) fructose contents in standard diets, and removing foods with a fructose content in the highest quartile for the amounts in the standard diet. Participants in both groups are prescribed a diet that contains 30 to 40% less than the participant's energy requirements. The primary endpoint is change in HOMA2-IR between baseline and week 24, and other outcomes are change in HDL-cholesterol, LDL-cholesterol, triglycerides , waist circumference to height ratio and BMI. The secondary endpoint is change in HOMA2-IR between week 24 and week 48 together with the outcomes noted above. Comparisons between groups for variables used to indicate IR levels are done with a Student's t test for unpaired variables or the Mann-Whitney U test if the distribution is not normal. Multivariate regression models will be used to control for confounding factors not accounted for in the study design, and for independent prognostic factors.Discussion: If the dietary intervention being tested, i.e., a diet low in fructose/sucrose, is able to reduce IR, the results - if translated into regular clinical practice - could provide a hitherto unavailable tool to prevent type-2 diabetes mellitus.Trial Registration: ISRCTN, ID: ISRCTN41579277 .

The article presents a double-blind, placebo-controlled clinical trial on Hibiscus sabdariffa L., or roselle, and its potential benefits for adult patients with metabolic syndrome (MetS). Topics include the effect of roselle calyces on high-sensitivity C-reactive protein (hs-CRP), lipid profile which includes triglycerides (TG) and lipoproteins, and oxidative stress or levels of malondialdehyde (MDA). Results support the ability of H. sabdariffa to decrease systolic blood pressure and serum TG.

Aim: The aim of our study was to investigate whether treatment with red yeast rice added with Coenzyme Q10 is associated with changes in endothelial function and arterial stiffness. Methods: This double blind, placebo-controlled, randomized clinical trial was carried out on 40 non-smoker moderately hypercholesterolemic subjects (ClinicalTrial.gov ID NCT02492464). After 4 weeks of diet and physical activity, patients were allocated to treatment with placebo or with an active product containing 10 mg monacolins and 30 mg Coenzyme Q10, to be assumed for 6 months. Endothelial reactivity and arterial stiffness have been measured through the validated Vicorder® device. Results: During monacolin treatment, patients experienced a more favorable percentage change in low density lipoprotein (LDL)-cholesterol (after monacolin treatment: -26.3%; after placebo treatment: +3.4%, p < 0.05). Endothelial reactivity (pulse volume displacement after monacolin treatment: +6.0%; after placebo treatment: -0.3%, p < 0.05), and arterial stiffness (pulse wave velocity (PWV) after monacolin treatment: -4.7%; after placebo: +1.1%, p < 0.05) also significantly improved only after monacolin treatment. Conclusion: The long-term assumption of the tested dietary supplement is associated with an improvement in LDL-cholesterolemia, endothelial reactivity and PWV in moderately hypercholesterolemic subjects.
