Background: Vitamin D (VD) deficiency has been related to several endocrine metabolic and cardiovascular diseases. Effect of VD supplementation on blood pressure (BP) in patients with diabetes is controversial. Objective: The aim of this study was to evaluate high-dose vitamin D supplementation effects on blood pressure of normotensive type 1 diabetes mellitus (T1DM) patients by 24-hour ambulatory blood pressure monitoring (ABPM). Methods: We performed a clinical trial including 35 T1DM normotensive patients, who received doses of 4,000 or 10,000 IU/day of cholecalciferol for 12 weeks according to previous VD levels. They underwent 24-hour ABPM, along with glycated hemoglobin, creatine, lipids profile and PCRus dosage before and after VD supplementation. Results and discussion: We found an expressive reduction of systolic and diastolic morning blood pressures (117±14 vs 112±14, p<0,05; 74±9 vs 70±10 mmHg, p<0,05, respectively) with no changes in other pressoric markers. Besides, we noticed a relation between levels of VD after supplementation and diastolic morning blood pressure (r= -0,4; p<0.05). Conclusion: Our study suggests an association between supplementation of high doses of vitamin D and the reduction of morning blood pressure in normotensive T1DM patients.

AbstractObservational and experimental data reinforce the concept that vitamin D is associated with the pathogenesis of arterial hypertension. We investigated the effect of a single dose of 100,000 IU of cholecalciferol, in office blood pressure (BP), and 24-h ambulatory blood pressure monitoring (ABPM) in patients with type 2 diabetes mellitus (DM), hypertension, and hypovitaminosis D. Forty-three patients were randomized to a placebo or cholecalciferol group. BP was assessed by office measurements and 24-h ABPM, before and after intervention. At week 8, a greater decrease in median ABPM values was observed in cholecalciferol supplementation than in the placebo group for systolic 24-h (− 7.5 vs. − 1; P = 0.02), systolic daytime (− 7 vs. − 1; P = 0.007), systolic nighttime (− 7.0 vs. 3; P = 0.009), diastolic 24-h (− 3.5 vs. − 1; P = 0.037), and daytime DBP (− 5 vs. 0; P = 0.01). Office DBP was also reduced after vitamin D supplementation. A single dose of vitamin D3 improves BP in patients with type 2 diabetes, hypertension, and vitamin D insufficiency, regardless of vitamin D normalization. Vitamin D supplementation could be a valuable tool to treat patients with type 2 DM, hypertension, and hypovitaminosis D.Trial registration: Clinicaltrials.gov NCT 02204527.

Background: Hypertension and vitamin D deficiency are prevalent among the elderly. This study evaluated the effects of vitamin D supplementation on changes in serum 25-hydroxyvitamin D (25(OH)D) levels and blood pressure (BP) in the elderly (age > 60 years). Methods: Randomized controlled trials from electronic databases on the elderly taking oral vitamin D, until the end of March 2019, were selected. Two reviewers independently screened the literature on the basis of specific inclusion criteria. The primary outcomes were serum 25(OH)D level, systolic BP (SBP), and diastolic BP (DBP) changes. Results: Our analysis revealed significant differences in serum 25(OH)D level changes between the vitamin D and control groups (mean difference [MD] = 13.84; 95% confidence interval [CI] = 10.21–17.47; P < 0.000). There were no significant differences in SBP and DBP changes between the vitamin D and control groups. Subgroup analysis revealed significant differences in SBP changes between the hypertensive and vitamin D-deficient subgroups (MD = –4.01; 95% CI = –7.45 to –0.57; P = 0.02 and MD = –1.91; 95% CI = –3.48 to –0.34; P = 0.02, respectively), and DBP changes only in the hypertensive subgroup (MD = –2.22; 95% CI = –4.1 to –0.34; P = 0.02). Conclusions: Vitamin D supplementation significantly increases 25(OH)D levels and seems beneficial in lowering BP, specifically in the elderly with elevated BP and vitamin D deficiency.

Background: Hypertension still became potential life threatening disease for human life. The prevalence of hypertension was high and tends to increase. Previous study suggested that there was a linier rise in blood pressure at increasing distances from the equator. More recent study indicated that vitamin D insuffi ciency may be associated with elevated blood pressure.Objective: To investigate the effect of vitamin D intake on blood pressure.Method: This was an experimental study with pre-post test group design. The subjects were 20 male Rattus norvegicus aged 8 weeks. Subjects were divided into 5 groups and each groups received treatment as follow: lived in dark cage and consumed vitamin D free diet for 1 – 13 days, then moved to normal cage (dark-light period) and given vitamin D per-oral of 0.25 μg/kg BW for 1 – 5 days. Data of systolic blood pressure was collected and analyzed with paired t test.Results: The absence of vitamin D in diet caused a signifi cant increase in systolic blood pressure (p=0.01) after 7 days of treatment in dark cage. While oral vitamin D supplementation of 0.25 μg/kg BW caused a signifi cant decline of systolic blood pressure since the fi rst day of vitamin D supplementation and the result appeared stronger after 4 days of treatment (p=0.001).Conclusion: Vitamin D intake had a strong infl uence on systolic blood pressure

Background: Preeclampsia (PE) is a disease specific to pregnancy affecting many bodily systems. This is characterized by high blood pressure and proteinuria after the 20th week of pregnancy. The objective of this study was to evaluate of association of vitamin D insufficiency with gestational hypertension in pregnant women.Methods: This was a cross-sectional study. A total of 104 pregnant women were included in the study. The diagnosis of gestational hypertension was confirmed using the “Report of the American College of Obstetricians and Gynaecologists’ Task Force on Hypertension in Pregnancy” criteria. Based on these criteria, patients with systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg (measured after a period of rest of four hours, twice daily) and proteinuria (≥300 mg protein/24 h) were diagnosed as gestational hypertension.Results: Vitamin D deficiency was found among 78.9% (90/114) women. There was no significant (p >0.05) difference in age of women between vitamin D deficient and sufficient. Vitamin D level was significantly (p = 0.0001) lower among the women between Vitamin D deficient (15.93±4.66) and sufficient (35.70±3.25). There was no significant (p >0.05) association of Vitamin D level with parity, family history of hypertension, blood pressure, gestational age and fasting blood glucose. There was significant (p = 0.0001) difference in BMI between Vitamin D deficient (30.10±4.95) and sufficient (24.04±2.75). Tobacco consumption was also associated with the level of Vitamin D. There was significant negative correlation between BMI and Vitamin D level (r = -0.56, p = 0.00011).Conclusions: The present study demonstrates that vitamin D plays a role in the ethology and pathophysiology of gestational hypertension. Among the population having the risk of vitamin D deficiency, the risk of pregnancy induced hypertension may be decreased through vitamin D supplementation.

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.
