Background. Vitamin D (25(OH)D) deficiency is a prevalent condition worldwide. However, the highest prevalence rates of 25(OH)D deficiency have been attributed to regions with higher latitude. A close association between 25(OH)D and cardio-cerebrovascular (CCV) risk factors and major health problems has been identified. Aim. To establish the prevalence of 25(OH)D deficiency and to investigate the relationship between 25(OH)D levels and CCV risk factors (blood cholesterol, triglycerides, glucose concentrations, body mass index, and systolic and diastolic blood pressure) in a cohort representative of Southern Italy. Methods. The prevalence of 25(OH)D levels was evaluated in 1200 subjects aged 25–74 years (600 males and 600 females), enrolled in the “VIP” (from Italian for Irno Valley Prevention) Project, whereas multiple linear regression analysis was used to determine the relationship between 25(OH)D levels and CCV risk factors. Results. Only 13.3% of females and 11.1% of males showed adequate serum concentrations of 25(OH)D (≥30 ng/ml), while 59.3% of females and 55.1% of males showed 25(OH)D deficient levels (<20 ng/ml). We observed an independent association between 25(OH)D concentrations and metabolic syndrome score, LDL cholesterol, HDL cholesterol, and corrected QT (cQT). Conclusions. We report a high prevalence of 25(OH)D deficiency across the largest Italian adult population studied so far and, in particular, the first across Southern Italy; furthermore, we provide data on the association between 25(OH)D deficiency and higher CCV risk factors.

The Relationship

AbstractGenetic variation in the apolipoprotein E (APOE) gene is associated with Alzheimer’s disease (AD) and risk factors for cardiovascular disease (CVD). DNA methylation at APOE has been linked to altered cognition and AD. It is unclear if epigenetic marks could be used for predicting future disease. We assessed blood-based DNA methylation at 13 CpGs in the APOE gene in 5828 participants from the Generation Scotland (GS) cohort. Using linear regression, we examined the relationship between APOE methylation, cognition, cholesterol, and the risks for AD and CVD. DNA methylation at two CpGs was associated with the ratio of total-to-HDL cholesterol, but not with cognition, or the risks of AD or CVD. APOE methylation could be involved in the levels of blood cholesterol, but there is no evidence for the utility of APOE methylation as a biomarker for predicting AD or CVD.

Uncertain Etiology

Background and objectives: Previous epidemiological studies have identified a group of heart diseases (here called heart diseases of uncertain etiology—HDUE) whose characteristics were rather different from cases classified as coronary heart disease (CHD), but frequently confused with them. This analysis had the purpose of adding further evidence on this issue based on a large population study. Materials and Methods: Forty-five Italian population samples for a total of 25,272 men and 21,895 women, free from cardiovascular diseases, were examined with measurement of some risk factors. During follow-up, CHD deaths were those manifested as myocardial infarction, other acute ischemic attacks, and sudden death of probable coronary origin, after reasonable exclusion of other causes. Cases of HDUE were those manifested only as heart failure, chronic arrhythmia, and blocks in the absence of typical coronary syndromes. Cox proportional hazards models were computed separately for CHD and HDUE, with 11 risk factors as possible predictors. Results: During an average of 7.4 years (extremes 1–16) there were 223 CHD and 150 HDUE fatal events. Male sex, age, smoking habits, systolic blood pressure, serum cholesterol, and plasma glucose were significantly and directly related to CHD events, while high density lipoprotein (HDL) cholesterol was so in an inverse way. The same risk factors were predictive of HDUE events except serum cholesterol and HDL cholesterol. Multivariable hazards ratio of serum cholesterol (delta = 1 mmol/L) was higher in the CHD model (1.24, 95% CI 1.11–1.39) than in the HDUE model (1.03, 0.5% C.I. 0.89–1.19) and the difference between the respective coefficients was statistically significant (p = 0.0444). Age at death was not different between the two end-points. Conclusions: CHD and HDUE are probably two different morbid conditions, only the first one is likely bound to gross atherosclerotic lesions of coronary arteries and linked to blood lipid levels. We reviewed the problem in epidemiological investigations and addressed inflammation as a potential cofactor to differentiate between CHD and HDUE.

The Relationship

Context: In animal and observational studies, adiponectin is associated with lipoprotein risk factors for cardiovascular disease. Objective: We analyzed data from a randomized clinical trial to evaluate the relationship between changes in adiponectin to changes in lipoprotein risk factors after an intervention that alters adiponectin levels. Design and Setting: Adiponectin levels were measured at baseline and follow-up, as were lipoprotein risk factors for cardiovascular disease, at academic medical centers and ambulatory care centers. Patients and Other Participants: Participants included 361 men and women with type 2 diabetes. Intervention: Intervention included randomization to treatment with glimepiride or pioglitazone for 72 wk. Main Outcome Measure: The relationship of treatment-related differences in adiponectin level to treatment-related differences in lipoprotein cardiovascular risk factors at 72 wk was evaluated. Results: Pioglitazone led to an increase in adiponectin compared with glimepiride. Compared with baseline, pioglitazone treatment at 72 wk led to an increase in low-density lipoprotein (LDL) and high-density lipoprotein (HDL) particle size and a decrease in very-low-density lipoprotein (VLDL) particle size and LDL particle number. Glimepiride treatment more modestly decreased LDL particle number and increased LDL particle size. At 72 wk, there were significant treatment group differences for HDL, LDL, and VLDL particle size, and triglyceride and HDL cholesterol level. The increase in adiponectin predicted treatment-related improvement for triglyceride and HDL cholesterol level and LDL and HDL particle size. Conclusion: Increased adiponectin contributed to treatment-related benefit in lipoprotein cardiovascular disease risk factors in obese diabetic subjects treated with pioglitazone. These results provide support for a model that mechanistically links changes in adiponectin level to changes in lipoprotein composition in humans.

The aim of the research is to study the availability of vitamin D among children of different age and pregnant women living in the Amur region. 339 residents of Blagoveshchensk (279 children of different age and 60 adults) were examined. Among them there were 129 toddlers, 90 children of preschool age of 3-6 years old, 60 adolescents of 15-17 years old and 60 adults (pregnant women) of 18-40 years old. In the blood serum the content of the metabolite of vitamin D [25(OH)D] was studied by high performance liquid chromatography. The assessment of risk factors for failure and deficiency of vitamin D was conducted by clinical and anamnestic data. The first results of the study have been presented. They indicate a high frequency of various vitamin D deficiency in the population of the Amur region. Among 339 residents of the Amur region 92 (27.1%) had an adequate availability of vitamin D, 144 (42.4%) had an insufficiency of 25(OH)D; at the same time vitamin D deficiency was identified in 90 (26.5%) with 1/3 of the child population and 1/4 of pregnant women. The level of 25(OH)D within normal limits found in 37.5% of children in the first year of life decreased till 3.6 % by 3 years old, with its deficit increasing from 29.1% to 50%, persisting at this level (45.5 percent) in 3-6 year-old children, declining till 23.3% in adolescents and till 23.3% in pregnant women. The average vitamin D in the studied age periods was the highest in the first year of life (36.14±4.3 ng/ml), and the lowest in 2-3 year-old children (19.31±14.68 ng/ml), with a gradual increase in 3-6 years old (21.77±0.96 ng/ml); in 15-17 years old (23.89±0.66 ng/ml) and in pregnant women it has reached a level of 27.75±0.18 ng/ml, remaining below normal values. Respiratory infections, digestion, bone and joint systems pathologies are the most important risk factors contributing to the low status of 25 (OH) D; their prevention, alongside with the correction of vitamin D deficiency can improve the health of the population of the Amur region.

AbstractEvidence associating serum 25-hydroxyvitamin D (25(OH)D) concentrations and cardiometabolic risk factors is inconsistent and studies have largely been conducted in adult populations. We examined the prospective associations between serum 25(OH)D concentrations and cardiometabolic risk factors from adolescence to young adulthood in the West Australian Pregnancy Cohort (Raine) Study. Serum 25(OH)D concentrations, BMI, homoeostasis model assessment for insulin resistance (HOMA-IR), TAG, HDL-cholesterol and systolic blood pressure (SBP) were measured at the 17-year (n 1015) and 20-year (n 1117) follow-ups. Hierarchical linear mixed models with maximum likelihood estimation were used to investigate associations between serum 25(OH)D concentrations and cardiometabolic risk factors, accounting for potential confounders. In males and females, respectively, mean serum 25(OH)D concentrations were 73·6 (sd 28·2) and 75·4 (sd 25·9) nmol/l at 17 years and 70·0 (sd 24·2) and 74·3 (sd 26·2) nmol/l at 20 years. Deseasonalised serum 25(OH)D3 concentrations were inversely associated with BMI (coefficient −0·01; 95 % CI −0·03, −0·003; P=0·014). No change over time was detected in the association for males; for females, the inverse association was stronger at 20 years compared with 17 years. Serum 25(OH)D concentrations were inversely associated with log-HOMA-IR (coefficient −0·002; 95 % CI −0·003, −0·001; P<0·001) and positively associated with log-TAG in females (coefficient 0·002; 95 % CI 0·0008, 0·004; P=0·003). These associations did not vary over time. There were no significant associations between serum 25(OH)D concentrations and HDL-cholesterol or SBP. Clinical trials in those with insufficient vitamin D status may be warranted to determine any beneficial effect of vitamin D supplementation on insulin resistance, while monitoring for any deleterious effect on TAG.

AbstractObjectiveTo investigate seasonal variations of vitamin D status at different latitudes and if these changes are accompanied by corresponding variations in certain health parameters in children living in a broad latitudinal range in Iran.DesignLongitudinal study.SubjectsIn total, 530 apparently healthy children aged 5–18 years were randomly selected from six regions of Iran with a latitudinal gradient from 29°N to 37·5°N. All anthropometric and biochemical assessments were performed twice during a year (summer, winter). High BMI (Z-score >1), low HDL cholesterol (<40 mg/dl, males; <50 mg/dl, females) and high TAG (>150 mg/dl) were considered cardiometabolic risk factors.ResultsSerum 25-hydroxyvitamin D (25(OH)D) showed between-season variation, with significantly higher concentrations (mean (sd)) in summer v. winter (43 (29) v. 27 (18) nmol/l; P<0·001). Change of circulating 25(OH)D between summer and winter was negatively correlated with change of BMI (r=−0·16; P<0·001), TAG (r=−0·09; P=0·04) and total cholesterol (r=−0·10; P=0·02) and directly correlated with change of height-for-age Z-score (r=0·09; P=0·04). Multiple stepwise linear regression analysis (β; 95 % CI) showed that winter serum 25(OH)D (−0·3; −0·4, −0·2; P<0·001), gender (boys v. girls: 9·7; 5·2, 14·1; P<0·001) and latitude (>33°N v. <33°N: 4·5; 0·09, 9·0; P=0·04) were predictors of change of serum 25(OH)D between two seasons.ConclusionsSummertime improvement of vitamin D status was accompanied by certain improved cardiometabolic risk factors, notably serum TAG, total cholesterol and BMI, in children.

Background and aims: : Systemic lupus erythematosus (SLE) is an autoimmune disease which involves various organs. Vitamin D is an essential ingredient in regulating the immune system. This study aimed to investigate the relationship between vitamin D and the severity of lupus activity. Materials and Methods: This case-control study was carried out on 38 patients with lupus on the basis of the American College of Rheumatology (ACR) criteria and 44 healthy subjects with no history of rheumatologic disease. To measure the level of 25-hydroxy vitamin D, venous blood samples (5 cc) were taken from each participant and the activity of the lupus disease was measured by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) scale. Finally, the chi-square test, independent sample t test, one-way ANOVA, and multiple linear regression analysis were used to measure multivariate effects. The level of significance was set to be P<0.05. Results: Thirty-five lupus patients and 40 healthy subjects were females (P=0.847). Vitamin D deficiency was observed in the case (42.1%) and control (11.4%) groups. The mean value of serum vitamin D3 level was 35.3 ng/mL in the control group, as well as 24.6 ng/mL and 21.3 ng/mL in patients with mild and severe SLE, respectively (P=0.024). Conclusion: In this study, high levels of 25-hydroxy vitamin D were observed among the healthy subjects compared to patients with SLE. Eventually, the level of vitamin D significantly decreased by increasing the severity of SLE activity.

Objective Low serum 25(OH)D levels are associated with cardiovascular disease (CVD) and some of its risk factors. However, in interventional studies, the effects of vitamin D supplementation have been uncertain, possibly due to inclusion of vitamin D-sufficient subjects. Our aim was therefore to examine effects of vitamin D supplementation on CVD risk factors in vitamin D-insufficient subjects. Design Double-blinded randomized controlled trial. Methods A 4-month interventional study with high-dose vitamin D (100,000 IU loading dose, followed by 20,000 IU/week) or placebo with measurements of blood pressure, lipids (total-, LDL- and HDL-cholesterol, triglycerides, apolipoproteins A1 and B), and glucose metabolism parameters (blood glucose, HbA1c, serum human receptors for advanced glycation end products (sRAGE), insulin, C-peptide and HOMA-IR). Results A total of 422 subjects with mean serum 25(OH)D level 34 nmol/L were included, with 411 subjects completing the study. Serum 25(OH)D levels increased with 56 nmol/L and decreased with 4 nmol/L in the vitamin D and placebo group, respectively. We found no statistically significant differences between the two groups in any of the measured CVD risk factors, except for a minor increase in sRAGE in the vitamin D group. Stratified analyses of subjects with low baseline serum 25(OH)D levels alone, or combined with blood pressure, lipid and HOMA-IR values above the median for the cohort, did not skew the results in favour of vitamin D supplementation. Conclusion Supplementation with vitamin D in subjects with baseline vitamin D insufficiency does not improve CVD risk factor profile.

Abstract Background Remnant-like particle cholesterol (RLP-C) is highly atherogenic, which is associated with atherosclerosis. However, RLP-C has not been routinely measured in the clinical practice. We estimated RLP-C levels using conventional lipid profiles and examined the association between estimated RLP-C and related factors including nutrient intake. Methods This study was performed in Uku town, Nagasaki prefecture, Japan in 2019. A total of 225 subjects were enrolled and directly measured RLP-C levels. Estimated RLP-C levels were defined as the following formula [total cholesterol − (LDL-cholesterol) − (HDL-cholesterol)]. Multivariate analyses were used to assess the relationship between estimated RLP-C and atherogenic factors. We calculated cut-off values on dichotomized RLP-C (< 7.5 mg/dL vs. ≥ 7.5 mg/dL) by receiver operating characteristic (ROC) curve. Results The mean values of directly measured RLP-C levels and estimated RLP-C were 4.0 mg/dL and 16.4 mg/dL, respectively. In the multiple stepwise linear regression analysis, directly measured and estimated RLP-C levels were independently and commonly associated with apolipoprotein E, triglycerides, and vegetable fat intake (inversely). Using ROC curves, we found the cut-off value of estimated RLP-C was 22.0 mg/dL. Conclusion We demonstrated that the estimated RLP-C levels using conventional lipid profiles may substitute for directly measured RLP-C and these levels were independently and inversely associated with vegetable fat intake in the community-dwelling Japanese population.

Uva Radiation

AbstractSeasonal variation in environmental meteorological conditions affect the incidence of infectious diseases. Ultraviolet A (UVA) radiation induces release of cutaneous photolabile nitric oxide (NO) impacting the cardiovascular system and metabolic syndrome, COVID-19 risk factors. NO also inhibits the replication of SARS-CoV. We therefore model the relationship between UVA radiation, derived from remote sensed data, and COVID-19 deaths for counties across the USA during their ‘UV vitamin D winter’ (Jan-April) adjusting for confounding including by temperature and humidity. The Mortality Risk Ratio (MRR) falls by 29% (40% -15% (95% CI)) per 100 (KJ/m2) increase in mean daily UVA. We replicate this in independent studies in Italy and England and estimate a pooled decline in MRR of 32% (48%-12%) per 100 KJ/m2 across the three studies.
