The aim: Is to establish a relationship between serum vitamin D level with carbohydrate and lipid indexes in women with autoimmune hypothyroid disease. Materials and methods: 146 women with autoimmune hypothyroid disease were examined in the period 2017-2019, who signed the informed consent. The mean age of women was 43.8 ± 0.7 years. Anthropometric, general clinical and biochemical examinations were performed including determination of lipid metabolism, hydrocarbon metabolism and establishment of vitamin-D status. Results: Vitamin D deficiency was found in 78.8%, insufficiency in 17.1% of women with autoimmune hypothyroidism. Statistical processing of results was carried out and established strong negative correlation between 25 (OH) D and Thyroid Peroxidase Antibody (r = -0,77) and thyrotropic hormone level (r = -0.72), р<0,05. Strong inverse correlations were found between vitamin D levels and body mass index (r=-0,74) and total cholesterol levels (r=-0,72), negative correlation of medium strength was with highdensity lipoprotein cholesterol (r=-0,58), triglycerides (r=-0,46), atherogenic coefficient (r=-0,65) and the HOMA-IR (r=-0,57), The values of p < 0.05 were considered reliable. Conclusions: The incidence of vitamin D hypovitaminosis in women with autoimmune thyroid disease is significantly higher than in the healthy population. Low vitamin D status is significantly associated with autoimmune thyroid dysfunction and determines the degree of metabolic disorders and cardiovascular risk in premenopausal women with autoimmune hypothyroid disease.

Background: The association between vitamin D status and inflammatory biomarkers and lipid profile is not well known, especially in adolescents. Therefore, the aim of the current study is to investigate the association of vitamin D status with serum lipids and inflammatory biomarkers, including IL-10, IL-6, hsCRP, and TNFR-2, in male adolescents. Methods and materials: A sample of seventy-one high school male students, aged 17 years old, from a high school in Tehran were enrolled in the study. They were divided into four groups including group with serum vitamin D below 25 (ng/mL) (SVD < 25; n = 36), 25 and above (ng/mL) (SVD ≥ 25; n = 35), negative-hsCRP (n = 48), and positive-hsCRP (n = 23). Weight, height, body mass index, dietary intake, serum lipids, and inflammatory biomarkers, including IL-10, IL-6, hsCRP, and TNFR-2, were measured. Results: In the (SVD < 25) group, the serum level of TNFR-2 was significantly higher compared to that in the (SVD ≥ 25) group. There was a significant negative association between serum TNFR-2 and vitamin D levels in the whole sample. We found significant lower levels of IL-10 in positive-hsCRP group compared to the negative-hsCRP group. In addition, there was a significant negative correlation between the serum vitamin D level and hsCRP in both hsCRP groups. The HDL level was lower in the (SVD < 25) group compared to that in the (SVD ≥ 25) group. Finally, there was a negative correlation between the serum HDL and hsCRP levels in the positive-hsCRP subjects. Conclusion: Based on the findings it can be concluded that serum vitamin D affects HDL and inflammation status. Although serum levels of HDL and inflammation status are both predictors of metabolic syndrome and cardiovascular disease, further studies are needed to prove it, especially in adolescents.

Vitamin D deficiency is a major health problem in the Saudi population. A negative association between blood pressure and vitamin D level has been suggested in several clinical and epidemiological studies and evidence for an effect of vitamin D in lowering blood pressure was reported. These findings indicate that 1,25(OH)2D3 deficiency may play a role in the pathogenesis of hypertension through its effect on the renin-angiotensin system. We are the first to investigate the correlation between blood pressure or renin concentration and vitamin D status in the Saudi population METHODS: we included 201 healthy Saudi premenopausal females (20-45 years old). Blood pressure was measured by a standardized method using an automated blood pressure monitor (BPTru). Fasting blood samples were collected from each participant after 20 minutes of rest in the seated position. Serum cholicalciferol, PTH and renin concentration were measured by sandwich chemiluminescence immunoassaymethod (DiaSorin, Italy). RESULTS: The analysis included 192 subjects who were normotensive (blood pressure <140/90 mmHg).  A total of  34% of women had a severe deficiency (vitamin D ≤ 12.5 nmol/L); 41% had moderate deficiency (vitamin D levels between 12.5 - 25 nmol/L);  23% had mild deficiency (vitamin D level ≥ 25 - < 50 nmol/L); and 2% had insufficiency (vitamin D level  ≥ 50 - ≤ 75 nmol/L). None had a sufficient level of ≥75 nmol/L.  The systolic blood pressure ranged from 79-130.5mmHg and the diastolic from 48.5-85.5 mmHg.  Both systolic and diastolic blood pressures were significantly higher in women that were in the lower 2 quartiles of vitamin D.  However, linear regression analysis adjusting for potential confounders showed that 25(OH)D level was not a predictor of either systolic or diastolic blood pressures.  A negative correlation (although not significant) was found between vitamin D level and plasma renin concentration in this study group. CONCLUSION: Vitamin D deficiency was highly prevalent among the study group. Vitamin D was a not a predictor of either systolic or diastolic blood pressure.  There was a negative correlation between vitamin D level and renin concentration although not statically significant. It is possible that any underlying relationship was obscured by the relatively young age group or due to the narrow blood pressure range of the studied population. A larger sample size including hypertensive subjects may be needed.

ABSTRACT Vitamin D deficiency is a global health problem, its role as an immune modulator being recently emphasized. Recent studies are increasingly suggesting that vitamin D plays a significant role in reducing the incidence and progression of autoimmune diseases. Furthermore, it was reported that patients with Hashimoto’s thyroiditis, an autoimmune thyroid disease had lower vitamin D levels [1]. We initiated a prospective study, for a period of 6 months with a study group represented by 160 patients admitted to the National Institute of Endocrinology “CI Parhon” in the period 2013 -2014. Patients were divided into 3 groups: 121 patients without thyroid pathology, 22 patients diagnosed with chronic autoimmune thyroiditis, who received 2000 IU cholecalciferol daily, 17 patients diagnosed with chronic autoimmune thyroiditis, which did not receive cholecalciferol. We found that patients with chronic thyroiditis have a poor vitamin D status with ATPO values negatively correlating with 25 (OH) vitamin D levels. Treatment with cholecalciferol not only improves vitamin D status but also lowers antithyroid antibodies titres. Keywords: vitamin D deficiency, chronic

Abstract. Background: Vitamin D deficiency (VDD) is a major public health problem. There are few comprehensive systematic reviews about the relationship between Vitamin D status and liver and renal disease in Iran. Methods: We systemically searched the following databases: Web of Science; PubMed; Cochrane Library; Scopus; Science Direct; Google Scholar and two Iranian databases (Scientific Information Database (SID) and IranMedex) up until November 2017 to identify all randomized control trials (RCTs), case control, cross-sectional and cohort studies investigating the association between vitamin D and any form of liver or kidney disease. Results: Vitamin D insufficiency, or deficiency (VDD), is highly prevalent in Iran, reports varying between 44.4% in Isfahan to 98% in Gorgan. There is also a high prevalence of VDD among patients with liver or kidney disease, and the administration of vitamin D supplements may have beneficial effects on lipid profile, blood glucose, liver function and fatty liver disease, and bone health. Low serum vitamin D levels are related with abnormalities in these laboratory and clinical parameters. Conclusion: VDD is prevalent in patients with chronic liver or renal disease in Iran. There appear to be several beneficial effects of vitamin D supplementation in vitamin D deficient patients with liver or kidney disease.

SummaryThe prevalence of both vitamin D deficiency and venous thromboembolism (VTE) is important in the elderly. Previous studies have provided evidence for a possible association between vitamin D status and the risk of VTE. Thus, we aimed to investigate the association between vitamin D levels and VTE in the population aged 75 and over included in the EDITH case-control study. The association between vitamin D status and VTE was analysed. We also analysed the monthly and seasonal variations of VTE and vitamin D. Between May 2000 and December 2009, 340 elderly patients (mean age 81.5 years, 32 % men) with unprovoked VTE and their controls were included. The univariate and multivariate analysis found no significant association between serum levels of vitamin D and the risk of unprovoked VTE. In the unadjusted analysis, a higher BMI was statistically associated with an increased risk of VTE (OR 1.09; 95 % CI 1.05–1.13) whereas a better walking capacity and living at home were associated with a decreased rate of VTE: OR 0.57; 95 % CI 0.36–0.90 and 0.40; 95 % CI 0.25–0.66, respectively. Although not significant, more VTE events occurred during winter (p=0.09). No seasonal variations of vitamin D levels were found (p=0.11). In conclusion, in contrast with previous reports our findings suggest that vitamin D is not associated with VTE in the elderly population.

Recent evidence indicated that transglutaminase 2 (TG2) is involved in the adaptive immune response. Peripheral blood mononuclear cells (PBMC) have largely been used to characterize molecular mechanisms occurring in the activation of immune response. Given that the maintenance of immune system functions requires an optimal vitamin D status, we aimed to assess the involvement of TG2/NF-κB signaling in cytokine production in PBMC isolated from adult subjects with different vitamin D status. We observed TG2 up-regulation and a significant positive correlation between TG2 expression and tumor necrosis factor (TNF)-α mRNA levels in PBMC of recruited patients. The mRNA levels of TG2 and TNF-α were higher in PBMC of subjects having hypovitaminosis D, namely plasma 25(OH)vitamin D3 levels lower than 50 nmol/L, than in those with normal vitamin D levels. Moreover, NF-κB up-regulation and nuclear translocation were detected, concomitantly with TG2 as well as TNF-α increased expression, in PBMC of vitamin D-deficient subjects. The present findings confirm that an increase in TG2 expression exacerbates the activation of NF-κB and the production of pro-inflammatory cytokines, and suggest a link between vitamin D deficiency, TG2 up-regulation, and inflammation.

Background: In the recent years there has been an increased understanding of the role that vitamin D plays in regulation of cell growth, calcium absorption and immunity and its impact on the developing fetus and maternal health is of significant concern. This study aims at evaluating the Vitamin D status in pregnant women and their newborns.Methods: A cross sectional study was done on 100 pregnant females according to inclusion and exclusion criteria. At the time of delivery, maternal blood was collected, and newborn samples were taken from newborn side of umbilical cord and sent for analysis.Results: The prevalence of Vitamin D deficiency has been found to be 85% of pregnant females and 91% of the newborns. Only 5% of pregnant females and 1% of the newborns showed Vitamin D sufficiency. Maternal and newborn vitamin D levels show a positive correlation. Mean maternal and newborn Vitamin D levels were found to be 16.78±7.04 ng/mL and 11.29±5.75 ng/ml.Conclusions: Vitamin D deficiency is highly prevalent among pregnant women in north India. Low maternal vitamin D levels lead to vitamin D deficiency in the newborns also.
