An extended study of the effect of Iranian village and urban flatbreads on the mineral balances of two men before and after supplementation with vitamin D†

Vitamin D deficiency is common in women with polycystic ovarian syndrome. Vitamin D plays an important physiologic role in reproductive functions of ovarian follicular development and luteinization through altering anti-müllerian hormone signaling, follicular stimulating hormone activity and progesterone production in human granulose cells. Vitamin D is precipitated in adipose fat tissues, making it notable to be used for the body as a result; obese people with high body mass index are already highly expected to have low levels of serum vitamin D.

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.

The Impact

Background: On March 11, 2020, the World Health Organization (WHO) announced the Coronavirus outbreak officially as a pandemic. This pandemic has led to new measurements to prevent viral spread. The measures included decreasing the person’s mobility outside homes with subsequent changes in the lifestyles, particularly in physical activity and eating habits. It has been noticed that consumption of some vitamins may help in preventing or reducing the symptoms of viral infection. Those vitamins include vitamin C, D and zinc. There is a common observation that the general public believes that the use of vitamins, especially vitamins C, D and zinc, reduces the chance of acquiring COVID-19. Objectives: The aim of this study was to determine the impact of COVID-19 pandemic on taking vitamins supplements by the Saudi general population in order to explore their believes regarding the protective value of these vitamins against COVID-19 infection. Subjects and Methods: This cross-sectional study was conducted using a self-administrated questionnaire that was designed, uploaded to the Google form and distributed online to the general Saudi population through the social media (Whatsapp, Twitter) as well as through email between August and December 2020. Statistical Packaged of Social Sciences program (SPSS) for Windows (version 17.0., Chicago: SPSS Inc) was used to analyze the data. A significant difference was considered when the p value is < 0.05. Student t-test and Chi-square (χ2) test were used to compare the studied variables as appropriate. Results: A total of 1043 participants were included in this study (64.9% females, 35.1% males). The mean age for them was 35.3±14.78 years. Only 9.3% (97 participants) were diagnosed to have COVID-19. About 28% of the participants were in contact with COVID-19 cases. Among participants diagnosed to have COVID-19 infection, (13% versus 29%) were taking vitamin C and (2% versus 15%) were taking zinc supplements daily during the 6 months before and after the pandemic, respectively, while (20% versus 25%) were taking vitamin D supplements weekly during the 6 months before and after the pandemic, respectively. Among participants who were in contact with COVID-19 cases, (8% versus 20%) and (3% versus 11%) were taking vitamin C and zinc supplements daily during the 6 months before and after the pandemic, respectively, while (14% versus 16%) were taking vitamin D supplements weekly during the 6 months before and after the pandemic Conclusion: The interest of taking multivitamin by Saudi population, such as vitamins C and D, zinc increased during and after the pandemic compared to that before it. There is no scientific evidence based on previous studies confirmed the role of dietary supplementation and multivitamins in preventing COVID-19 infection, therefore, effective education on the rationale use of vitamins during COVID-19 pandemic should be emphasized at local and/or national levels.

Purpose: To investigate the effect of weekly single high dose vitamin D supplementation on serum 25-hydroxyvitamin D [25(OH)D], and non-specific musculoskeletal pain in female nurses. Methods: In this prospective study in Kashan/Iran, from April 1, 2014, through September 30, 2014, the 150 nurses with vitamin D deficiency received the weekly pearls of 50,000 units of vitamin D3 for 10 weeks. The serum level of 25(OH)D was measured before and after supplement therapy. The subjects were also asked to complete the Extended Nordic Musculoskeletal Questionnaire. All analyses were conducted with SPSS version 16. Results: After 10 weeks of intervention there was [Formula: see text][Formula: see text]ng/mL increase in 25(OH)D. The 82 nurses (54.7%) had 25(OH)D in normal range, while the 68 nurses (45.3%) were still vitamin D deficient. Weight could explain 15.4% increase in 25(OH)D. Before intervention 135 (90%), of nurses reported musculoskeletal pain in at least one region, after intervention this number decreased to 72.7%. There was a statistically significant improvement in musculoskeletal pain in neck, shoulders, upper back, lower back, hips/tights, knees, and ankles/feet after intervention. Conclusions: The weekly single high dose of vitamin D for 10 weeks could resolve vitamin D deficiency in about half of the patients. Patients with non-specific musculoskeletal pain might benefit from vitamin D supplementation.

Before And After

1. The response of circulating 1,25-dihydroxyvitamin D [l,25-(OH)2D] to challenge with vitamin D treatment both before and after 7–10 days of prednisone therapy (25 mg/day) was investigated in five anephric subjects, six patients with chronic renal failure (CRF), two patients with vitamin D intoxication and four patients with hypoparathyroidism. 2. In anephric subjects serum 25-hydroxyvitamin D [25-(OH)D] rose from 58 ± 48 (sd) to 377±221 (sd) nmol/l after administration of 150 μg of 25-(OH)D3 for 1 month. Serum l,25-(OH)2D, which was barely detectable in only two out of five patients under basal conditions, rose to 30 ± 21 pmol/l after 2 weeks of therapy with 25-(OH)D3, but fell to 10 ± 5 pmol/l during prednisone treatment. 3. In CRF patients circulating l,25-(OH)2D rose from 37 ± 24 to 58 ± 24 pmol/l during 25-(OH)D3 therapy, but fell to 41 ± 31 pmol/l during prednisone treatment. In two patients with rheumatoid arthritis, hypercalcaemia due to vitamin D intoxication was associated with raised levels of 1,25-(OH)2D (288 and 317 pmol/l). Administration of prednisore resulted in suppression of l,25-(OH)2D levels (132 and 96 pmol/l respectively) and reduction of serum calcium to within the normal range. 4. In the hypoparathyroid patients prednisone therapy did not affect circulating 25-(OH)D levels but serum l,25-(OH)2D fell from 192 ± 42 to 117 ± 23 pmol/l and serum calcium from 2.41 ± 0.21 to 2.20 ± 0.05 mmol/l. 5. These findings indicate that a steroid sensitive extrarenal production of l,25-(OH)2D may occur in all subjects with a threshold serum concentration of the precursor 25-(OH)D.

ObjectiveConcentrations of 50 and 75 nmol/l are proposed as serum 25-hydroxyvitamin D (25(OH)D) target for older people from the view of bone health. We evaluated vitamin D status of elderly Finnish women in light of these definitions, its relationship to bone mineral density (BMD) and turnover, and improvement by summer sunshine.DesignPopulation-based study.MethodsA total of 1604 ambulatory women aged 62–79 years were studied; 66% used vitamin D supplements. Serum 25(OH)D3was measured with HPLC before and after summer, and heel BMD in spring. In subgroups, serum parathyroid hormone (PTH) and type I procollagen aminoterminal propeptide (PINP) were analyzed.ResultsIn spring, 60.3% of the women had 25(OH)D3≤50 nmol/l, and the target of 75 nmol/l was reached by 9.1%. For supplement users, the respective numbers were 52.1 and 11.9%. Serum 25(OH)D3did not determine BMD or bone turnover measured by serum PINP. Summer sunshine increased serum 25(OH)D3by 17.4% (P<0.0001), but in autumn 84% of the subjects remained under the target of 75 nmol/l. In supplement users, PTH remained stable but decreased in others during summer (P=0.025).ConclusionsVitamin D status of elderly Finnish women is suboptimal if 25(OH)D3levels of 50 or 75 nmol/l are used as a threshold. It is moderately increased by supplement intake and summer sunshine. However, 25(OH)D3concentrations did not influence bone density in terms of serum PINP and bone turnover rate.
