Vitamin D deficiency is highly prevalent worldwide. It has been associated with heart failure (HF) given its immunoregulatory functions. In-vitro and animal models have shown protective roles through mechanisms involving procollagen-1, JNK2, calcineurin/NFAT, NF-κB, MAPK, Th1, Th2, Th17, cytokines, cholesterol-efflux, oxLDL, and GLUT4, among others. A 12-month follow-up in HF patients showed a high prevalence of vitamin D deficiency, with no seasonal variation (64.7–82.4%). A positive correlation between serum 25(OH)D concentration and dietary intake of vitamin D-rich foods was found. A significant inverse correlation with IL-1β (R = −0.78), TNF-α (R = −0.53), IL-6 (R = −0.42), IL-8 (R = −0.41), IL-17A (R = −0.31), LDL-cholesterol (R = −0.51), Apo-B (R = −0.57), total-cholesterol (R = –0.48), and triglycerides (R = −0.32) was shown. Cluster analysis demonstrated that patients from cluster three, with the lowest 25(OH)D levels, presented the lowermost vitamin D intake, IL-10 (1.0 ± 0.9 pg/mL), and IL-12p70 (0.5 ± 0.4 pg/mL), but the highest TNF-α (9.1 ± 3.5 pg/mL), IL-8 (55.6 ± 117.1 pg/mL), IL-17A (3.5 ± 2.0 pg/mL), total-cholesterol (193.9 ± 61.4 mg/dL), LDL-cholesterol (127.7 ± 58.2 mg/dL), and Apo-B (101.4 ± 33.4 mg/dL) levels, compared with patients from cluster one. Although the role of vitamin D in the pathogenesis of HF in humans is still uncertain, we applied the molecular mechanisms of in-vitro and animal models to explain our findings. Vitamin D deficiency might contribute to inflammation, remodeling, fibrosis, and atherosclerosis in patients with HF.

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.

Background: It is unclear whether vitamin D deficiency is associated with a higher risk of cardiovascular disease, and through what biochemical pathways this could occur. We investigated the relationship between serum 25-OH vitamin D and typical cardiovascular risk markers as well as incident myocardial infarction (MI) in a large group of high-risk individuals from the community of Calgary, Alberta, Canada. Methods: Calgary Laboratory Services databases were queried for age, sex, body mass index (BMI), personal healthcare number (PHN) and first available serum 25-OH vitamin D measure from patients who received an electrocardiogram or urine creatinine clearance test from 2010-2013. Data was linked by PHN to first available laboratory results for total cholesterol, HDL cholesterol, triglycerides, LDL cholesterol, fasting glucose and HbA1c as well as Alberta Health Services hospital discharge data for first myocardial infarction (ICD-10: I21.1-9) occurring after 25-OH vitamin D measurement. Multiple linear and logistic regression were used to examine all associations. Results: There were 36 000-50 000 complete patient records for analysis of each of the risk markers, with a median follow-up of 8-11 months. A 30 mmol/L increase in serum 25-OH vitamin D was associated with significantly (p<0.001) lower total cholesterol (-0.07 mmol/L), LDL cholesterol (-0.06 mmol/L), triglycerides (-0.14 mmol/L), fasting glucose (-0.12 mmol/L), and HbA1c (-0.13% mmol/L), but higher HDL cholesterol (+0.06 mmol/L) after adjusting for age, sex, BMI, monthly hours of sun-exposure and time between measures. Among these individuals, there were 458 cases of MI occurring after 25-OH vitamin D measurement, with a median follow-up of 1 year. In a case-cohort analysis that included 2500 controls, a 30 mmol/L increase in 25-OH vitamin D was associated with a 21% (p<0.001) lower odds of MI after multivariate adjustment. This association was strongly attenuated after adjusting LDL, HDL, fasting glucose and HbA1c. Conclusion: In a high-risk group of community patients from Calgary, Alberta, Canada, higher serum 25-OH vitamin D was associated with a lower risk of MI, which was explained by changes in commonly measured cardiovascular risk markers. Further study is needed to determine whether changes in cardiovascular risk markers are causally related to changes in 25-OH vitamin D.

The problem of structural changes in peripheral blood erythrocytes in patients with chronic heart failure in combination with vitamin D deficiency during exercise stress remains insufficiently studied. Vitamin receptors are located on smooth myocytes, endothelial cells, cardiomyocytes and blood cells. It affects the state of the cell membrane, the contractile function of the myocardium, the regulation of blood pressure, cardiac remodeling and reduction of left ventricular hypertrophy. Therefore, it is important to assess the level of vitamin D in blood plasma in individuals with chronic heart failure and to identify the effect of its deficiency on the state of peripheral red blood cells when performing a 6-minute walk test. A total of 75 patients of the main group with chronic heart failure stage II A, I–II functional class with different levels of vitamin D deficiency were examined. The control group included 25 patients with chronic heart failure stage II A, functional class I–II without signs of vitamin D deficiency. The average age of patients was 57.5 ± 7.5 years. All patients were asked to undergo the 6 minutes walking test. The level of total vitamin D in plasma was determined by enzyme immunoassay. Morphological studies of erythrocytes were performed on the light-optical and electron-microscopic level. The obtained results showed that patients of the main group with chronic heart failure had a decrease in vitamin D by 2.2 times compared with the control group. Correlation analysis showed a directly proportional relationship between vitamin D deficiency and the number of red blood cells of a modified form and red blood cells with low osmotic resistance. Dosed exercise stress in patients with chronic heart failure against a background of vitamin D deficiency leads to an increase in the number of reversibly and irreversibly deformed erythrocytes and a decrease in their osmotic stability. This indicates a disorder in the structural integrity of their membrane and can have negative consequences for the somatic health of such patients.

AbstractRethinking food systems from production to consumption, in order to provide better nutritional inputs at lower environmental cost, is a priority challenge for a sustainable future. Pulses present benefits that may improve the sustainability of our systems and diets, such as their ability to restore soils in nitrogen and their high contents in proteins, fibers and minerals. However, pulses also contain several bioactive compounds such as phytates or tannins that can negatively affect mineral absorption. Additionally, we recently showed in the laboratory that these bioactives, together with fibers and saponins, could negatively impact fat-soluble vitamin bioavailability. The objective of this study was thus to follow up vitamin D (as a model of fat-soluble vitamin) and iron (as a model of mineral) transfer to the aqueous phase of the bolus during digestion of meal containing or not pulses. To this aim, we performed in vitrodigestion using tests meals made of beef (as a model of meat) and/or semolina (as a model of cereals) and/or chickpeas (as a model of pulses). To identify the compounds responsible for the observed effects, we also performed in vitrodigestion using test meals made of potatoes supplemented or not in fibers, phytates, tannins and saponines. Vitamin D bioaccessibility and iron solubility were expressed as the ratio of vitamin D or iron recovered in the aqueous phase of the digestion on the total amount of vitamin D or iron recovered in the whole digesta, at the end of the digestion.Our results showed that the presence of chickpeas within a meal induced a significant decrease of both vitamin D bioaccessibility (up to -56%, p < 0.05) and iron solubility (up to -28%, p < 0.05) compared to meals containing only meat and/or semolina. However, this effect was largely compensated for vitamin D by the fact that this vitamin was less stable (loss > 50%, p < 0.05) during the digestion of meal containing meat compared to meals containing only plant-based foods (i.e. semolina and chickpeas). Among the different bioactives, tannins appear to be the most deleterious regarding iron solubility, while both phytates and tannins were responsible for a decreased in vitamin D bioaccessibility.Our results confirm that in some conditions, the presence of pulses within a meal can be deleterious regarding vitamin D and iron bioavailability. These data thus encourage research to propose dietary and technological solutions to tackle pulse negative effects on micronutrient bioavailability.

AbstractSeveral previous epidemiological studies from developed countries have shown that an unhealthy dietary pattern affects plasma lipid levels and inflammation biomarkers. We assessed the cross-sectional associations between dietary patterns and cardiovascular risk factors among 961 adults from a multi-city cohort in South America. We conducted a principal component analysis to derive dietary patterns. As outcomes, we examined plasma levels of apo A-I, apo B, high-sensitivity C-reactive protein (hs-CRP), LDL-, HDL- and serum total cholesterol and TAG. The crude and adjusted changes in each outcome were estimated for quartiles of dietary patterns using multivariable linear regression models. The prudent pattern (PP) characterised by higher intake of fruits, vegetables, fish, seafood, whole cereal and low-fat dairy products was associated with reduced plasma concentrations of apo B (−8·5 mg/l), total cholesterol (−18·8 mg/dl) and LDL-cholesterol (−16·5 mg/dl) and hs-CRP (−1·6 mg/l) in men. In women also reduced plasma concentrations of apo B (−6·6 mg/l), total (−12·0 mg/dl) and LDL (−9·3 mg/dl). The ‘Western-like’ pattern characterised by higher intake of eggs, pastry and cakes, pizza, snacks, refined grains, red meat, vegetable oils and poultry was not significantly associated with any of the selected serum lipid or inflammatory biomarkers. The explained variances were 10·3 and 7·4 %, respectively. The PP was associated with better lipid profile, mainly lower atherogenic particles (apo B) and LDL-cholesterol and serum total cholesterol. This study provides possible evidence of a prudent diet in South American populations to help reduce the burden of CVD.
