AbstractEpidemiological studies have shown a link between vitamin D deficiency and numerous pathologies such as cancers, immunity diseases, cardiovascular diseases, hypertension, type 2 diabetes, and obesity. Recent studies in vitro and in animal models demonstrated an impact of vitamin D on adipose tissue and adipocyte biology. Such observations are of particular interest and provide mechanistic explanations on the relationship between vitamin D deficiency and obesity.

Objective: Vitamin D is a multifunctional vitamin for our body. Type 2 diabetes mellitus (T2DM) is a common metabolic disease. Whether T2DM affects the serum 25(OH)D level has not been reported. The objective of this study was to reveal the extent to which vitamin D is present in the population in East China and to explore the relationship between serum 25(OH)D and T2DM. Methods: The cohort was selected based on a large investigation named Survey on Prevalence in East China including 12,702 participants aged 21-92 years old. All the participants completed the questionnaire and went through a physical examination. Fasting blood samples were collected to test serum 25(OH)D and other metabolism-related indicators. AVONA was used to test the significance of differences among groups. Multinomial logistic regression was used to assess the association of T2DM with serum 25(OH)D level. Results: The overall percentage of vitamin D deficiency was 80.55% (male 74.1%, female 85.0%). Men with lower serum 25(OH)D level had high value in homeostasis model assessment of insulin resistance and HbA1c. The serum 25(OH)D level of those who were diagnosed with T2DM was higher than that in non-diabetics. The serum 25(OH)D level of pre-diabetes was the highest. T2DM patients trended to have higher serum 25(OH)D levels. Conclusion: Vitamin D deficiency is common among the people in East-China. T2DM patients had higher levels of serum 25(OH)D. The relationship between vitamin D and T2DM is intriguing. It seemed that vitamin D was either irrelevant directly to T2DM or resisted in T2DM patients.

Дефицит витамина D, а также сердечно-сосудистые заболевания (ССЗ) и связанные с ними факторы риска широко распространены во всем мире и часто возникают одновременно. Давно известно, что витамин D является неотъемлемой частью метаболизма костей, хотя недавние данные свидетельствуют о том, что витамин D играет ключевую роль в патофизиологии других заболеваний, включая сердечно-сосудистые заболевания. В этом обзоре мы стремимся обобщить самые последние данные об участии дефицита витамина D в развитии основных факторов риска сердечно-сосудистых заболеваний: артериальной гипертензии, ожирения и дислипидемии, диабета 2 типа, хронического заболевания почек и эндотелиальной дисфункции. Кроме того, мы приводим самые последние данные наблюдений, а также интервенционные данные о влиянии витамина D на сердечно-сосудистые заболевания. Vitamin D deficiency, as well as cardiovascular disease (CVD) and associated risk factors, are widespread throughout the world and often occur concurrently. Vitamin D has long been known to be an essential part of bone metabolism, although recent evidence suggests that vitamin D plays a key role in the pathophysiology of other diseases, including cardiovascular disease. In this review, we seek to summarize the most recent evidence on the involvement of vitamin D deficiency in the major risk factors for cardiovascular disease: hypertension, obesity and dyslipidemia, type 2 diabetes, chronic kidney disease, and endothelial dysfunction. In addition, we provide the most recent observational data as well as interventional evidence on the effects of vitamin D on cardiovascular disease.

Background: Vitamin D is increasingly investigated as having a role in Type 2 Diabetes Mellitus (T2DM) and its cardiovascular and renal complications. Objective: This study aimed to investigate the association between 25-hydroxyvitamin D (25-OHD) and biomarkers of cardiovascular and renal complications, including cystatin-C. Methods: This cross-sectional study involved 117 participants with T2DM that was not complicated with cardiovascular or renal diseases except hypertension. 25-OHD was measured by electrochemiluminescence immunoassay, while cystatin-C was measured by enzyme-linked-immunosorbent-assay. Other biomarkers, including lipids, creatinine, urea and glycemic measures, were determined by the routine biochemistry assays. Results: The prevalence of vitamin D deficiency was 74.36%. There was no significant difference in cardiovascular and renal biomarkers, including glucose, HbA1c, lipids, urea, creatinine and cystatin-C between participants with adequate and deficient vitamin D (p-values>0.05). Participants with adequate vitamin D were older in age, more obese and having lower eGFR (p-values<0.05). 25-OHD was weakly correlated with age, duration of DM, urea, creatinine and inversely correlated with eGFR (rvalues< 0.32, p-values<0.05). Although creatinine and cystatin-C were directly correlated (r=0.42, pvalue< 0.001), cystatin-C and 25-OHD were not correlated (p-value>0.05). Hypertensive participants were more obese, having a longer duration of DM and higher urea and cystatin-C compared to nonhypertensive participants (p-values<0.05). Binary logistic regression analysis revealed that hypertension could be predicted from increased BMI. Conclusion: 25-OHD was not found to be correlated with cardiovascular risk biomarkers, but it was correlated with renal biomarkers, including urea, creatinine and eGFR. Cystatin-C and 25-OHD were not observed to be correlated to each other, but both were correlated to renal function. Obesity was a significant predictor of hypertension.
