Abstract Introduction Vitamin D is known to have immunomodulatory functions and has action on chronic inflammatory processes, such as nasal polyposis. Objective The present study assessed the levels of 25-hydroxy vitamin D and high-sensitivity C-reactive protein (hs-CRP) in patients with nasal polyposis, as compared with healthy control subjects, and identified their association with disease severity in nasal polyposis. It further assessed the levels of 25-hydroxyl vitamin D and hs-CRP in patients with nasal polyposis and atopy and compared it with patients with nasal polyposis without atopy. Methods This was a cross-sectional study involving 2 groups: 80 patients with nasal polyposis and 80 healthy subjects. In patients with nasal polyposis, the disease severity is assessed by the sino-nasal outcome test (SNOT20) and by the Lund & Mackay staging system. Levels of 25-hydroxy vitamin D and hs-CRP were measured by enzyme-linked immunosorbent assay (ELISA). Result The mean 25-hydroxyl vitamin D levels (ng/ml) was 12.01 ± 7.29 for cases and 22.87 ± 14.95 for controls, with p < 0.0001. The mean hs-CRP levels (mg/L) was 5.99 ± 2.74 in cases and 2.41 ± 1.95 in controls, with p < 0.0001. The severity of polyposis correlated negatively with serum levels of 25-hydroxy vitamin D and positively with hs-CRP. Conclusion The study has thus shown significant correlation between vitamin D deficiency and inflammation in patients with nasal polyps.

The Impact

Summary Background There is controversy about the impact of acute illness on vitamin D levels. This study was carried out to assess the influence of perioperative fluid loading on 25-hydroxy-vitamin D [25(OH)D] levels. The study evaluated the clinical utility of a commonly available chemiluminescence assay (ECLIA, IDS-iSYS) and liquid chromatography/mass spectrometry (LC-MS/MS) in the diagnosis of vitamin D deficiency in this setting. Methods In this prospective observational pilot study in adult patients undergoing cardiovascular surgery on cardiopulmonary bypass (CPB), blood samples drawn at preoperative baseline (t1), after weaning from CPB (t2), on intensive care unit (ICU) admission (t3) and on the first (t4) and second (t5) postoperative days were analyzed. Results A total of 26 patients (130 samples) were included in this study. Fluid loading by CPB led to a median reduction of 25(OH)D by −22.6% (range −54.5% to −19.5%) between t1 and t2. Cohen’s kappa (κ) for method agreement for vitamin D deficiency (tested cut-off values 20 ng/ml and 12 ng/ml), was κ = 0.291 (p < 0.001) and κ = 0.469 (p < 0.001), respectively. The mean difference between measurements by ECLIA and LC-MS/MS was 4.8 ng/ml (±5.7), Pearson’s r for correlation was 0.73 (p < 0.001). The biologically inactive C3-epimer did not contribute to 25(OH)D levels assessed by LC-MS/MS. Conclusion The 25(OH)D measurements by chemiluminescence assays can noticeably deviate from those measured by LC-MS/MS, which can be considered the unequivocal gold standard. These assays may still be acceptably reliable in the screening for vitamin D deficiency, especially in the setting of low vitamin D levels. Stricter definitions, e.g. serum 25(OH)D levels lower than 12 ng/ml, may be used to diagnose deficiency with low false positive rate.

Aim: Data on the prevalence of vitamin D deficiency in Lithuania are scarce. The aim was to assess the reserves of vitamin D in different age groups of out-patients, regarding the season of the year. Methods: Data on serum 25-hydroxyvitamin D (25(OH)D) levels from blood tests made in 2012–2014 were obtained from one laboratory, and a retrospective cross-sectional analysis was performed. Results: A total of 9581 subjects were included. The mean age of the participants was 33 ± 23 years. The mean levels of vitamin D were higher in males than in females (p < 0.001). The highest mean 25(OH)D levels were in 0–9-year-old group, the lowest were in the 10–19-year-old group and in the group of participants that were 70 years and older (p < 0.001). The lowest vitamin D status was found in January, February, March, and April. The highest status was found in August and September. Overall, vitamin D deficiency, sufficiency, and hypervitaminosis were detected in 67%, 21%, and 12% of cases, respectively. Most cases with hypervitaminosis were in the group of children up to 2 years of age. Conclusion: Vitamin D status demonstrated clear seasonality. Significant sex-related differences of vitamin D statuses were also determined. Vitamin D deficiency was very prevalent in almost all age groups. Young children (aged up to 2 years) are of special interest for further research involving other types of 25(OH)D assays, such as those based on high-performance liquid chromatography (HPLC), since the real prevalence of “true” vitamin D hypervitaminosis in Lithuania’s children is still to be determined.

Variant Alleles

This cross-sectional study enrolled 180 patients at a private family practice in Virginia. Total serum vitamin D concentrations were obtained weekly from January 30, 2013, through March 30, 2013, in consecutive patients regularly scheduled for laboratory work at the practice. Patients were categorized into 2 groups and analyzed for variant alleles in vitamin D receptor ( VDR; rs2228570), cytochrome P450 2R1 ( CYP2R1; rs10741657), 7-dehydrocholesterol reductase ( DHCR7; rs12785878), and group-specific component ( GC; rs2282679) to determine whether variants of those alleles influenced total serum 25(OH)D concentrations. One-hundred and eighty patients were enrolled, with 40 (22%) being sufficient, 25-hydroxy vitamin D level 25(OH)D ≥ 30 ng/mL, and 140 (78%) being insufficient, 25(OH)D < 30 ng/mL. Of the 4 genes, 2 genes, CYP2R1 (rs10741657) and GC (rs2282679), demonstrated a significant association related to vitamin D status. Subjects with 1 or more variant alleles at rs10741657 were almost 3.7 (odds ratio [OR] 3.67; 95% confidence interval [CI]: 1.35-9.99) times more likely be insufficient in vitamin D and subjects with 1 or more variant alleles at rs2282679 were about half (OR 0.42; 95% CI: 0.18-0.93) as likely to be insufficient in vitamin D. Allelic variations in CYP2R1 (rs10741657) and GC (rs2282679) affect vitamin D levels, but variant alleles on VDR (rs2228570) and DHCR7 (rs12785878) were not correlated with vitamin D deficiency, 25(OH)D < 30 ng/mL.

25 Hydroxy Vitamin D

AbstractThe association between serum 25-hydroxy vitamin D (25(OH)D) antiepileptic drugs (AEDs) and bone health in individuals with epilepsy has been recognized for more than 30 years. Several studies indicate an increased risk for bone loss in patients on antiepileptic medication as well as low levels of serum 25(OH)D. Patients on polytherapy AED are at a higher risk of adverse drug effects compared with those on monotherapy. The present study assessed serum 25(OH)D levels in children receiving AED and compares those children receiving monotherapy versus polytherapy. This is a prospective cross-sectional study conducted in a tertiary care hospital setting on children with seizures receiving AEDs for period of more than 6 months. Participants were enrolled in three groups: 25 children on monotherapy, 25 children on polytherapy, and 25 healthy controls. Serum 25(OH)D level was performed for all children and analyzed. Serum 25(OH)D levels were normal in 52%, insufficient levels in 43.3%, and deficient in 6.7% of children. Vitamin D level was insufficient in 40% of children receiving monotherapy and 52% receiving polytherapy AED. Vitamin D deficiency was present in 4% in monotherapy group and 16% in polytherapy group which was statistically significant (p-value 0.047). Vitamin D deficiency was higher in children receiving AED compared with normal controls. Vitamin D deficiency and insufficiency were higher in children on polytherapy. Our study emphasized the importance of monitoring vitamin D levels in children receiving AED to detect abnormalities in vitamin D levels.

9638 Background: There is emerging evidence in the literature to suggest a protective role of vitamin D in cancer survival. Vitamin D status is not routinely assessed, despite the high prevalence of malnutrition in this population. We hypothesized that malnutrition could contribute to vitamin D deficiency, and therefore expected mean serum 25-hydroxy-vitamin D [25(OH)D] levels to be significantly lower in malnourished oncology patients. Methods: A consecutive case series of 737 cancer patients seen at Cancer Treatment Centers of America between Jan-June 08. Nutritional status was assessed using Subjective Global Assessment (SGA) and serum albumin. SGA categorizes patients into 3 distinct classes of nutritional status; well nourished (SGA-A), moderately malnourished (SGA-B) and severely malnourished (SGA-C). Serum albumin was divided into 2 groups: >=3.6 g/dl and <=3.5 g/dl. Mean serum 25(OH)D was compared across 3 categories of SGA using ANOVA and across 2 categories of serum albumin using 2 sample t test. Results: Of 737 patients, 302 were males and 435 females. The mean age at presentation was 55.7 years (SD = 10.2). The most common cancer types were lung (133, 18%), breast (131, 17.8%), colorectal (97, 13.2%), pancreas (86, 11.7%), prostate (44, 6%) and ovarian (38, 5.2%). The mean serum albumin and serum 25(OH)D was 3.5g/dl (SD = 0.6) and 21.9 ng/ml (SD = 13.5) respectively. There was no significant difference in the mean vitamin D levels across serum albumin (p = 0.76). The mean vitamin D levels across the 3 classes of SGA also showed no statistically significant difference ( Table ). Conclusions: Contrary to what we expected, vitamin D deficiency was found to be prevalent in cancer regardless of nutritional status. No significant differences were found across the 3 classes of SGA. Based on these results, screening for vitamin D deficiency and aggressive vitamin D repletion should be considered for all people with cancer.

Background: Research examining the role of vitamin D deficiency and the development of menstrual disorders in women is of widespread interest. Studies have been published showing that supplementation with high-dose vitamin D can lead to the restoration of the menstrual cycle. We lack adequate information regarding the effect of vitamin D levels on the physiology of menstruation and further on fertility in women of reproductive age due to the contradictory results reported by studies. Objective: To study the association of 25-hydroxy vitamin D with menstrual cycle characteristics including long and short cycle length and cycle irregularity. Materials and Methods: In this cross-sectional study, serum vitamin D levels of 166 women attending an outpatient department with menstrual irregularities after excluding all obvious causes of menstrual disorders (n = 83) between April-June 2019 were measured and were compared with women of similar profiles with complaints other than menstrual irregularities (n = 83). Results: A decreased level of vitamin D was associated with a 13.3 times odds of an irregular cycle (OR (95% CI): 13.30 (5.79-30.60), p < 0.001). 25-hydroxy vitamin D was not associated with age or body mass index. We found a significant difference (p < 0.001) in mean vitamin D levels among the females with irregular cycles vs. regular cycles. Conclusion: Vitamin D plays a role in the physiology of reproduction specific to the menstrual cycle and ovulation. Long-term prospective studies assessing the exact cutoff value and the exact dose of supplementation required are needed.

Introduction. Vitamin D deficiency is a common health problem that occurs in various countries. Vitamin D deficiency is linked to various diseases such as kidney failure, liver damage, atherosclerosis, obesity and psychiatric disorders such as depression and schizophrenia. This study aimed to analyze the correlation between serum vitamin D levels and schizophrenia severity. Methods. Schizophrenia patients who visited the Inpatient and Outpatient Clinic Department of Psychiatry of the Dr. Soetomo Hospital Surabaya. This was a cross-sectional observational study, conducted in December 2017 - April 2018 . The subjects consisted of 53 schizophrenia patients, vitamin D levels < 30 ng /mL (35 (66.04%); > 30 ng/mL (18 (33.96%). Serum vitamin D levels test by enzyme linked fluorescent assay (ELFA) method using Vidas. The severity of schizophrenia was measured using a positive and negative syndrome scale (PANSS) score. Results. Mean serum vitamin D levels in schizophrenia were 23.45 ± 9.16 ng / mL, serum vitamin D levels in males were 24.36 ± 9.80 ng / ml and females 21.96 ± 7.98 ng / ml. The mean serum vitamin D level and PANSS scores of positive symptoms was 16.42 ± 8.50. The mean serum vitamin D level and PANSS scores of negative symptoms was 15.60 ± 6.12. The mean serum vitamin D level and PANSS scores of general psychopathology symptoms was 29.51 ± 10.29. The statistical results showed no association between vitamin D levels and PANSS scores. Conclusion. The results of this study indicated low serum vitamin D levels in schizophrenia. There was no association between serum vitamin D levels and the severity of schizophrenia using PANSS scores.

Background: The range of normal closure time of the anterior fontanelle (AF) is generally regarded to be 4 to 26 months. The objectives of this study was to find out the prevalence of subclinical vitamin D deficiency and hypothyroidism in children aged 18-36 months with open AF.Methods: This is a hospital based, cross-sectional study done over a period of 24 months, in which thyroid function tests and 25-hydroxy-vitamin D levels were done for healthy children aged 18-36 months with open AF; the latter was also done for equal numbers (n=30) of age and sex matched children with closed AF for control values. The mean vitamin D levels and proportion of children of various categories based on vitamin D levels among both the groups were compared.Results: Open AF was seen in 37 children. Seven of them had obvious causes of delayed AF closure and were excluded. In the remaining 30 children, none of the children had abnormal thyroid function tests. 23.3% of the study group had low vitamin D levels; but, the levels were low even in 37% of control group. The mean vitamin D level of the study group (39.05±17.11 ng/ml) was similar to the control group (37.3±14.74 ng/ml).Conclusions: Neither subclinical vitamin D deficiency nor subclinical hypothyroidism accounted for delayed AF closure in this study.

Vasopressor Use

The use of cardiopulmonary bypass (CPB) in cardiac surgery often leads to a systemic inflammatory response. Up to 25% of patients undergoing CPB for cardiac surgery are reported to develop vasoplegic syndrome in the acute postoperative period, in which the patients are refractory to vasopressors. The purpose of this study is to assess vitamin D deficiency as a risk factor for vasoplegia after using CPB. We performed a retrospective review of 1322 patients undergoing adult cardiac surgery requiring CPB. Forty-six patients with previously recorded 25-hydroxy vitamin D (25(OH)D) levels within 6 months of surgery met the conditions of this study. The mean level of 25(OH)D was 32.7 ng/mL (standard deviation [SD] = 15.1). The mean age of patients was 67 (SD = 10.1) years old, most were male (63%) and white (78%). Average CPB time was 140 ± 44 minutes. Postoperative vasopressor use was compared to individual preoperative 25(OH)D levels. As a secondary end point, postoperative vasopressor use and vasoplegia were analyzed between 3 groups: Vitamin D deficient defined as 25(OH)D ≤20 ng/mL (n = 7), vitamin D insufficient defined as 25(OH)D between 20 and 29 ng/mL (n = 15), and vitamin D sufficient defined as 25(OH)D ≥30 ng/mL (n = 24). There was no correlation between vitamin D levels and postoperative vasopressor use. The mean doses of postoperative vasopressor use were 0.088 µg/kg/min (standard error of the mean [SEM] = 0.032), 0.085 µg/kg/min (SEM = 0.037), and 0.072 µg/kg/min (SEM = 0.024) of norepinephrine equivalents for the vitamin D deficient, insufficient, and sufficient groups, respectively. Incidence of vasoplegia for each group was the following: 0.143 for vitamin D deficient, 0.067 for vitamin D insufficient, and 0.125 for vitamin D sufficient. In this pilot study, there does not appear to be a relationship between vitamin D and vasopressor use following cardiac surgery utilizing CPB; however, there appears to be a trend toward an increased vasopressor usage in patients with decreased vitamin D levels. A larger sample size and a prospective analysis are warranted to further assess the significance of the relationship between vasoplegia and vitamin D deficiency. With further investigation, vitamin D has the potential to become a low-cost, low-risk therapeutic for improving outcomes in CPB surgery.

Introduction: Vitamin D is a hormonal precursor that in addition to known roles, may have an important effect on mental disorders such as depression. Therefore, this study was performed to determine the extent of vitamin D deficiency and depression and their relationship in thyroid patients referred to The clinic of Yazd Diabetes Center has been performed. Methods: The present study is a cross-sectional-analytical study that was performed on 150 thyroid patients referred to the Yazd Diabetes Center Clinic. Results: In this study, 150 thyroid patients including 55 men and 11. women with a mean age of 41.40± 7.61years participated. The mean score of Beck depression among these patients was 28.71± 8.34 .The mean level of vitamin D in these patients was 20.58 ± 7.21  ng / ml so that a total of 85% of thyroid patients were in the group of insufficient levels of vitamin D. A significant negative correlation was observed between depression score and serum vitamin D levels (r = -0.79 and p <0.001). Conclusion: The results of this study indicate a high prevalence of depression and vitamin D deficiency in thyroid patients. Another finding of this study was the relationship between vitamin D deficiency and depression, so that the less vitamin D in the body, the lower the rate of depression in The person becomes more. The use of vitamin D supplements in the treatment of thyroid patients with depression, as a clinical trial, can be a good solution in the treatment of patients.
