Background and objectives: Hypertension is a global health problem and a major risk factor for cardiovascular diseases. Vitamin D deficiency is closely related to high blood pressure and the development of hypertension. This study investigated the relationship between the vitamin D and blood pressure status in healthy adults, and their 8-year follow-up was added. Materials and Methods: A total of 491 healthy middle-aged participants without any chronic illness, ages 21 to 67 at baseline, were divided into two groups as non-optimal blood pressure (NOBP) and optimal blood pressure (OBP). NOBP group was divided into two subgroups: normal (NBP) and high normal blood pressure (HNBP). Serum 25-hydroxy vitamin D levels were measured with the immunoassay method. 8-year follow-up of the participants was added. Results: The average vitamin D level was detected 32.53 ± 31.50 nmol/L in the OBP group and 24.41 ± 14.40 nmol/L in the NOBP group, and a statistically significant difference was found (p < 0.001). In the subgroup analysis, the mean vitamin D level was detected as 24.69 ± 13.74 and 24.28 ± 14.74 nmol/L in NBP and HNBP, respectively. Together with parathyroid hormone, other metabolic parameters were found to be significantly higher in the NOBP. During a median follow-up of 8 years, higher hypertension development rates were seen in NOBP group (p < 0.001). Conclusions: The low levels of vitamin D were significantly associated with NBP and HNBP. The low levels of vitamin D were also associated with the development of hypertension in an 8-year follow-up.

Sodium Bicarbonate Infusion

Background. The sodium bicarbonate infusion test evaluates the function of the parathyroid glands. The present study aims to evaluate the range of parathyroid response in healthy individuals and the potential influence of various factors.Methods. Fifty healthy volunteers were subjected to the test. Levels of vitamin D, calcium, albumin, and PTH were measured before infusion. PTH was measured at 3, 5, 10, 30, and 60 minutes after infusion.Results. A curve describing the response of parathyroids to the test was drawn. Twenty percent of the subjects had blunted PTH response. No significant difference was observed between normal and blunted responders concerning age, BMI, baseline PTH, or calcium levels. Nonetheless, there was a significant difference in vitamin D levels (P=0.024).Interpretation. The test is easy to perform and may be used for everyday screening. It has to be clarified whether our observations are, at least partly, produced due to the presence of individuals with a constitutively blunted response or if low levels of vitamin D decrease the ability of the parathyroids to respond. Whichever the case, PTH response of normal individuals to sodium bicarbonate infusion test is more varied than previously thought and vitamin D levels influence it.

Abstract Background Vitamin D deficiency is frequently present in inflammatory bowel disease (IBD) with a higher incidence in Crohn’s disease (CD) than in ulcerative colitis (UC). Given the involvement of the alimentary tract, many factors can contribute to vitamin D deficiency. The aim of the study was to investigate the association of vitamin D deficiency according to body mass index (BMI) in adult patients with IBD. Methods A cross-sectional study was conducted on a cohort of 152 IBD patients, 68.1% (n = 104) CD and 31.9% (n = 48) UC. The mean age of the total study population was 37.3±11.8 years and 57.3% (n = 87) were male. All patients were adult, Caucasian and without vitamin D supplementation. Patients were recruited during one year period. Results Out of all IBD patients, 60.5% (n = 92) had vitamin D deficiency, 32.2%, (n = 49) insufficiency and 7.2% (n = 11) sufficiency. According to BMI categories there were 12.5% (n = 19) obese patients, 27.6% (n = 42) overweight, 51.3% (n = 78) with normal body weight, and 8.6% (n = 13) underweight. There was a significant difference in vitamin D levels according to different BMI categories in terms of underweight patients having the lowest vitamin D levels; underweight 29.84±11.94 mmol/l, normal 46 ± 20.7 mmol/l, overweight 48±20.1 mmol/l, obese 51±15.3 mmol/l. In addition, there was a significant correlation of vitamin D levels and BMI values (Rho = 0.212, 95% CI 0.069–0.345, p = 0.004), which was more clearly observed in the lower range of BMI values (Figure 1). Male underweight patients had lower levels of vitamin D compared with female patients (26.6 ± 9 vs. 34.7 ± 5.6, p &lt; 0.05). Both patients with CD and UC had significant positive correlation of vitamin D levels and BMI values (UC Rho=0.40, 95% CI 0.16–0.59, p = 0.001, UC Rho = 0.27, 95% CI 0.01–0.05, p = 0.044). However, when comparing vitamin D levels according to phenotype, a significant difference in vitamin D levels was observed in underweight CD (28.4 ± 11.1) comparing to underweight UC patients (40.6 ± 10.6), p &lt; 0.05. In logistic regression analysis, CD phenotype was risk factor for vitamin D deficiency (OR 2.18 95% CI 1.01–4.72, β = 1.22, p = 0.04). Conclusion Our results on untreated IBD patients show a high proportion of vitamin D deficiency both in CD and UC, and significant correlation of vitamin D levels and BMI values, especially in the lower range of BMI values. Moreover, underweight CD patients have lower vitamin D levels comparing to UC. This suggests the need for regular vitamin D monitoring and supplementation especially in IBD patients at risk.

Abstract Abstract 2139 Background: African Americans have lower vitamin D levels than the general population, which is thought to be due to decreased utilization of ultraviolet rays to convert vitamin D into an active form. Sickle cell patients have even lower vitamin D levels than African American controls. Preliminary studies at Tulane University correlated low vitamin D levels with markers of hemolysis (decreased hemoglobin (Hgb), increased reticulocyte count and lactate dehydrogenase (LDH)). Our main question was whether vitamin D deficiency in sickle cell patients is due to lack of outdoor activity or diet, or increased vitamin D metabolism during bone marrow turnover secondary to hemolysis. Design and Methods: 80 adult sickle cell patients received pain, dietary, and outdoor activity level surveys. Vitamin D 25-hydroxy (25(OH)D), hemolytic lab markers (Hgb, Hct, LDH, total bilirubin, and reticulocyte count) were obtained. Results: Baseline Assessment: Vitamin D levels were available on 70 patients: 24.3% were normal or mildly deficient (≥20 ng/mL), 30% moderately deficient (10-<20 ng/mL), and 45.7% severely deficient (<10 ng/mL). We could not verify a correlation between LDH and 25(OH)D levels, but there was a trend towards increased total bilirubin in patients severely deficient in vitamin D (p = 0.06). Severely anemic patients (Hgb 5-<7 gm/dL) had significantly lower average 25(OH)D levels (p = 0.02). When comparing patients with moderately and severely deficient 25(OH)D levels to patients with no or mild deficiency, there was a significantly increased use of healthcare facilities (see Table 1). Though there was no significant difference in intake of fish, cheese, or eggs, there was a significant decrease in milk intake (see Table 1). There was no significant difference in days spent in bed or time spent outdoors (see Table 1). Subjectively, patients did not report increased frequency of mild to moderate pain, vasocclusive crises, or use of pain medications in the moderately and severely vitamin D deficient groups but they did report higher rates of hospitalization due to sickle cell crises (p = 0.03, 0.005 respectively). Effects of Vitamin D replacement: 56 patients took vitamin D replacement. After replacement, there was no difference in frequency of pain and pain medicine use, or days in the hospital and ER. However, pain levels appeared to be less intense (see Table 2). There was a trend towards fewer days spent in the hospital and ER (p = 0.089) in the 6 months following vitamin D replacement and there were significantly fewer Sickle Cell Day Hospital visits (p = 0.037). Conclusions: Though we could not correlate vitamin D deficiency with LDH as a marker of hemolysis, lower Hgb levels seemed to be predictive of more severe vitamin D deficiency. Patients with more severe vitamin D deficiency did not report to have increased pain frequency or pain medication use, but had more ER visits and hospitalizations. When vitamin D was replaced, it did not decrease pain frequency, but it did decrease severity. We conclude that vitamin D replacement could lessen pain in sickle cell patients and thus utilization.

Abstract Background: Vitamin D deficiency is a global health problem, it is assessed by measuring serum 25-hydroxivitamin D (25(OH) D), nevertheless epidemiological data for many countries remains underreported.Objectives:To study the prevalence of vitamin D deficiency throughout the calendar year in a large cohort recruited ina multiethnic Transcarpathian region of Ukraine.Methods: In this retrospective study 25(OH)D serum concentration was measured during all 12 months of the year 2019 by electrochemoluminescent assay on the automatic analyzer Cobas e411 in 1,823 subjects, including both children and adults (1551 females (85.03%) and 273 males (14.97%)). ResultsThe mean 25(OH) D concentration in adults demonstrates significantly lower levels compared to children (22.67±8.63 ng/ml vs. 26.00±10.72 ng/ml respectively, p<0.001). Adult women expressed significantly lower mean annual serum 25 (OH) D concentrations in comparison to men (22.29±8.46 ng/ml vs. 25.75±9.38 ng/ml respectively, p< 0.001). In contrast, children did not show a significant difference between sexes (girls 24.98±10.38 ng/ml vs. boys 27.01±11.01 ng/ml, p=0.2003). In the winter months, 25(OH)D levels fell below 20 ng/ml in 51,74 % of adult population of Thranscarpathia, and in 12.91%, - below 12 ng/ml.ConclusionsThe results of this study contradict the previously reported evaluations of the vitamin D levels in Ukraine which were assessed by measuring serum 25(OH) D. Specifically, only approximately half of the studied population is vitamin D deficient during winter season. This study features the most representative sample size in Ukraine to date.

Abstract Background: Accumulating evidence indicates that vitamin D deficiency has been increased globally since the last two decades. However, the majority of these studies concerned on cities and there is scant information regarding the prevalence of vitamin D in rural areas. The main aim of this study was to investigate the prevalence of vitamin D deficiency and its associated risk factors among rural population in Bushehr province which has the longest border with the Persian Gulf.Methods: The rural inhabitants with ≥25 years old from three mountainous, plain, and seashore areas of Bushehr province were selected through a stratified multi-cluster random sampling method. After obtaining the participants’ demographic and anthropometric data and their past medical history, serum 25- hydroxy vitamin D was measured using ELISA.Results: A total of 1806 (means±SD, 46.30± 14.22 years old) rural subjects (34.84% males and 64.88%) participated in this study. The prevalence of vitamin D deficiency, insufficiency and sufficiency were 27.87%, 50.39% and 21.74%, respectively. The deficiency of vitamin D in women was higher than men (OR=1.27, 95% CI: 1.05 to 1.54, P=0.040). There was a positive significant correlation between age and serum vitamin D levels. Men with vitamin D deficiency had higher BMI (P=0.008); this association was not observed among women (P=0.74). There was no significant difference between the food items consumption frequencies, and vitamin D status (P>0.05). The mountainous, and plain areas had the highest and lowest vitamin D levels, respectively.Conclusion: Although, Bushehr province is located in a sunny part of Iran, the prevalence of vitamin D deficiency was high among its rural population. The shift of their life styles patterns and rapid industrialization in these rural areas may be responsible. Therefore, the enrichment of dietary sources with vitamin D and the use of vitamin D supplements are recommended to tackle the high prevalence of vitamin D deficiency in the rural population of the northern part of the Persian Gulf.

Background Coronavirus disease-19 (COVID-19) is an ongoing pandemic causing considerable fatalities worldwide. Vitamin D modulates the immune response through effects on various cells, such as: macrophages, B and T lymphocytes, neutrophils, and dendritic cells. Aim To explore whether supplementation of vitamin D, in the form of a single intramuscular cholecalciferol injection, to patients with diabetes, COVID-19, and low vitamin D levels could improve the prognosis of those patients. Methods This was a placebo-controlled randomized prospective study. The study has two arms as follows: the intervention arm (40 vitamin D deficient diabetes elderly patients that acquired SARS-CoV-2), compared to the control arm (16 elderly diabetes patients, with deficient vitamin D with SARS-CoV-2). Patients in the intervention arm were given vitamin D as a single intramuscular injection (200,000 IU); patients in the control arm were given placebo. The primary outcome was mortality within 6 weeks of the diagnosis of COVID-19. Clinical, laboratory, treatment, and outcome data were recorded after 6 weeks of follow-up. Results No significant difference in 6 weeks mortality was observed between patients who received vitamin D and patients who received placebo (17.5% vs 18.8%, p = 0.838). Age, presence of hypertension, and chronic obstructive pulmonary disease were independent predictors of mortality at 6 weeks. Conclusion Vitamin D supplementation did not reduce the severity or mortality of COVID-19 at 6 weeks. Further large scale studies are required to explore the effect of vitamin D therapy on survival in patients with diabetes mellitus who acquire COVID-19.

Abstract Postmenopausal status has been associated with an unfavorable phenotype tied to hormonal and metabolic changes, which collectively could contribute to an increased risk of cardiovascular disease. Vitamin D deficiency is frequent in postmenopausal women and may be linked to this phenotype and especially to an increased risk of developing hypertension. Vitamin D actions are modulated by the vitamin D receptor (VDR), and metabolic abnormalities have been associated with VDR gene variants in different populations. The aims of the present study were to assess the vitamin D levels, prevalence of vitamin D deficiency and genotypes of Fok-I, Bsm-I, Apa-I and Taq-I polymorphisms in the VDR gene and to determine whether vitamin D deficiency and VDR gene variants are associated with blood pressure levels and systemic arterial hypertension by the 2017 ACC/AHA definition in postmenopausal women. We conducted a cross-sectional study of biobanked blood samples from 339 postmenopausal women with no evidence of clinical disease. Blood pressure strata were defined according to the 2017 ACC/AHA cutoffs. Circulating 25(OH)D levels were considered deficient if &lt;20 ng/mL. Genotype analysis was performed by RT-PCR with allelic discrimination assays. Mean serum total 25(OH)D levels were 22.99±8.54 ng/mL, and 40.1% of participants were deficient in vitamin D. Overall, 7.7% had elevated blood pressure, 36.6% had stage 1 and 37.8% had stage 2 hypertension. Mean total (p=0.014) and free 25(OH)D levels (p=0.029) were lower in women with stage 2 hypertension than in those with normal blood pressure. The CC+CT genotypes of Bsm-I and the AA+AG genotypes of Taq-I polymorphisms were more frequent in women with stage 2 hypertension (Bsm-I CC+CT: 85.8% vs. TT: 14.2%, p=0.045; Taq-I AA+AG: 91.3% vs. GG: 8.7%, p=0.021). A higher prevalence ratio of stage 2 hypertension was associated with age (PR 1.058; 95%CI 1.033-1.083; p&lt;0.001), BMI (PR 1.046; 95%CI 1.025-1.068; p&lt;0.001), vitamin D deficiency (PR 1.333; 95%CI 1.016-1.749; p=0.038) and Taq-I polymorphism (PR 1.764; 95%CI 1.030-3.019; p=0.039). Women with vitamin D deficiency and the AA+AG genotype of Taq-I polymorphism were 33% and 76% more likely to have stage 2 hypertension, respectively, but these analyses lost significance when adjusted for age and BMI. In conclusion, the present results suggest that vitamin D deficiency and Taq-I polymorphism are associated with stage 2 hypertension, depending on age and BMI, in postmenopausal women.

Background and objectives: Vitamin D deficiency is now a global concern. Industrialization, urbanization and the decreasing participation in outdoor activities, with consequent sunlight deprivation, are thought to be the key factors in the increasing prevalence of vitamin D deficiency among general population of many countries. It is presumed that healthy, adequately sun-exposed people should maintain adequate vitamin D levels. However, studies within this population are scarce. Hence, this study was conducted to find out the actual vitamin D status in healthy, adequately sun-exposed population living in coastal district of Bangladesh. Material and Methods: One hundred and forty healthy fishermen living in costal district of Cox’s Bazar (210 25' North, 910 59' East) of Bangladesh were enrolled in this study. Relevant data and blood samples were collected during August 2018, one of the months with lower zenith angle and higher UV index. Chemiluminescent micro-particle immunoassay (CMIA) was used to measure 25-hydroxy vitamin D3. Other relevant biochemical parameters measured were random blood glucose (RBG), serum creatinine, albumin, calcium, phosphate, alkaline phosphatase and intact parathyroid hormone (iPTH). Results: Mean vitamin D level of the study population was 27.04±7.20 ng/ml. Based on the cut off value of Endocrine Society, 70.7% of the study population had low vitamin D levels of which 26 (18.6%) and 73 (52.1%) were in vitamin D deficient (<20ng/ml) and insufficient (20 – 29.99 ng/ml) categories respectively. Vitamin D level was normal in 41 (29.3%) subjects. There was no significant difference in iPTH level between groups with low and normal vitamin D levels (p>.05, 95%CI= -5.68226, 1.21086). Conclusion: The unexpectedly high prevalence of vitamin D deficiency in this healthy and adequately sun-exposed population raises the question regarding the validity of the current cutoff value being used to assess the vitamin D status of Bangladeshi population. Future studies should be carried out to determine nation-specific, local cutoff values for vitamin D sufficiency. Ibrahim Med. Coll. J. 2019; 13(2): 35-39

Background: Low vitamin D levels are common in patients with foot and ankle disorders. We have previously demonstrated that juveniles diagnosed with osteochondritis dissecans (OCD) have a high prevalence of vitamin D deficiency. Moreover, there is evidence that OCD might be related to vitamin D deficiency in general. However, whether or not hypovitaminosis D is associated with OCD of the talus has yet to be elucidated. Methods: The aim of this study was to determine serum vitamin D levels [25(OH)D] of patients diagnosed with traumatic and idiopathic OCD of the talus. The vitamin D status of patients was measured and correlated to age, sex, season, etiology, laterality, degree of disease, and nicotine abuse. Moreover, parathyroid hormone and serum calcium levels of patients were obtained to assess for severe vitamin D deficiency and secondary hyperparathyroidism. Between January 2015 and December 2017, 65 patients with a mean age of 38.9 years and a total of 68 lesions were identified. Results: In total, 75.4% of patients had low vitamin D levels with a mean overall 25(OH)D level of 24.2 ng/mL. Specifically, 35.4% of patients were vitamin D deficient; another 40% were vitamin D insufficient, and only 24.6% of patients presented with sufficient vitamin D levels. Statistical analysis showed no significant difference comparing vitamin D levels of patients with idiopathic OCD to patients with traumatic OCD. Conclusion: We could not find any significant differences in the vitamin D status of patients with OCD of the talus compared with patients with foot and ankle disorders in general. However, we found that vitamin D deficiency was frequent in patients presenting with traumatic and idiopathic OCD of the talus. We believe it might be beneficial to routinely assess and treat the vitamin D status of patients. Level of Evidence: Level III, retrospective comparative study.
