Study aimed to assess the level of 25-OH-cholecalciferol(vitamin D) and the relation with cholesterol, proteins and glycaemia levels in patients with cystic fibrosis. 58 patients underwent for the annual evaluations and were tested for vitamin D deficiency, as the centre�s protocol requires, besides dosage of cholesterol, glycaemia and proteins levels. Serum levels of 25-hydroxycholecalciferol were compared to levels of cholesterol, proteins and glycaemia, using Pearson correlation and logistic regression. The average value of 25-OH-cholecalciferol was 22,9 ng/mL, suggesting an important deficiency and different stages of 25-OH-cholecalciferol deficiency was found in the majority of patients. Nor a positive correlation neither negative relationship was found between vitamin D and cholesterol (r=0,23), glycaemia or proteins level. Vitamin D levels are not related to cholesterol or proteins in our study. Although cystic fibrosis is characterised by liposoluble vitamins deficiency and lipids impaired digestion, other factors influence the seric levels of vitamin D and lipids.

Abstract Aim: To study the vitamin D levels in toddlers with recurrent wheezing.Methods: In this prospective observational study, 108 children aged 1-3 years with recurrent wheezing and 41 healthy age and sex matched controls were included. The clinical, demographic, socio-economic, food habits, and sun exposure of both the groups were assessed. The serum levels of vitamin D were measured and Asthma predictive index (API) of all the cases was calculated. Spearman or Pearson correlation coefficients were used to see relationship of different variables with Vitamin D.Results: Among 108 cases and 41 controls we enrolled, majority of them had vitamin D deficiency or insufficiency. The difference in vitamin D levels in the two groups was not statistically significant (p=0.0619). We found no significant difference in the vitamin D levels between, urban and rural population, vegetarians and non-vegetarians, adequately and inadequately sun light exposed children. There was also no correlation between the vitamin D levels and the number of wheezing episodes in the last 1 year. There was no significant correlation between the number of criteria of API positive and the vitamin D levels.Conclusion: Our study showed that the overall prevalence of vitamin D deficiency is very high among toddlers with recurrent wheezing. We conclude that vitamin D rich diet and sunlight exposure cannot prevent vitamin D deficiency in Indian toddlers. National programme for universal supplementation of vitamin D is required to control this epidemic of vitamin D deficiency.

Abstract Background Adequate levels of vitamin D are important for women of childbearing age as vitamin D helps maintain the pregnancy and ensures proper maternal and fetal bone metabolism and fetal skeletal development. However, vitamin D deficiency is a health problem prevalent in women of all ages, worldwide. This study aimed to determine the current status of serum vitamin D levels and the risk factors for vitamin D deficiency among South Korean nurses of childbearing age. Methods Serum levels of 25-hydroxyvitamin D (25[OH]D) were measured in 1594 registered nurses aged 20 to 45 years who are participants in an ongoing prospective cohort study of the Korean Nurses’ Health Study initiated in 2013. The participants completed surveys about demographic and occupational characteristics and physical and psychological health. We examined associations with vitamin D deficiency through multivariable logistic regression analysis. Results The average blood 25(OH) D concentration of the participants was 12.92 ng/mL (4.0–63.4 ng/mL), while the prevalence of vitamin D deficiency (< 20 ng/mL) was 89% (1419/1594). Multivariable logistic regression showed that significant risk factors for vitamin D deficiency included month of sampling (there was a lower level of vitamin D deficiency in winter than in spring, summer, or fall), age (women in their 20s had a lower vitamin D level than those in their 30s and 40s), and stress symptoms. Vitamin D levels were not associated with body mass index, physical activity, and depressive symptoms. Conclusions This study showed a high prevalence of vitamin D deficiency in Korean female nurses. Serum levels of vitamin D were associated with age and season. Vitamin D deficiency should be recognized as one of the primary health concerns among young women. More proactive actions, such as vitamin D supplements and food fortification, are needed to improve vitamin D deficiency in high-risk groups.

Abstract Background Studies on the association between vitamin D levels and allergen sensitization have reported conflicting results. We aimed to evaluate the association between low vitamin D levels and sensitization to 59 aeroallergens in Korean adults. Methods We retrospectively reviewed serum 25-hydroxyvitamin D (25[OH]D) measurements of participants (n = 57,467) in a healthcare center between May 2003 and June 2020. Serum 25(OH)D levels were categorized as follows: severe deficiency (< 10 ng/mL), deficiency (10 to < 20 ng/mL), insufficiency (20 to < 30 ng/mL), and sufficiency (≥ 30 ng/mL). Among all subjects, 1277 simultaneously underwent the multiple allergen simultaneous test. Multiple linear and logistic regression analyses were used to estimate coefficients and odds ratios (ORs) with 95% confidence interval (CI) for the association between serum vitamin D deficiency and aeroallergen sensitization after adjustment for potential confounders. Subgroup analyses were conducted for the types of aeroallergen (house dust mites, pollens, animal dander, foods, cockroach, and fungus). Results Vitamin D deficiency, defined as serum 25(OH)D level < 20 ng/mL, was noted in 56.4% of participants. There were significant differences in serum 25(OH)D levels according to sex, age, season, and bone mineral density (all P < 0.001). In multiple linear regression analyses, serum 25(OH)D levels were significantly lower in young subjects (adjusted coefficient [95% CI], 0.188 [0.101, 0.275]) and during winter (− 4.114 [− 6.528, − 1.699]). However, no significant association was observed between serum 25(OH)D levels and allergen sensitization (adjusted coefficients [95% CI], − 0.211 [− 1.989, 1.567], P = 0.816). In multivariate logistic regression analyses, male sex, young age, and winter season were significant risk factors for vitamin D deficiency. However, allergen sensitization showed no significant association with 25(OD)D levels after adjusting for confounders (adjusted OR [95% CI], 1.037 [0.642, 1.674] in insufficiency; 0.910 [0.573, 1.445] in deficiency; 0.869 [0.298, 2.539] in severe deficiency groups, P for trend = 0.334). There were consistent findings across subgroups regarding type of aeroallergen sensitized. Conclusion Vitamin D deficiency was prevalent but was not significantly associated with aeroallergen sensitization in Korean adults. To the best of our knowledge, this is the first large-scale study to evaluate the association between vitamin D deficiency and sensitization to 59 different aeroallergens.

Background: Deficiency of vitamin D is quite prevalent among elderly population or postmenopausal women worldwide and may affect various function of the body. The status of its deficiency with their relation with other variables are not well explored in perimenopausal women.Methods: 100 perimenopausal women from the department of obstetrics and gynaecology were selected without having known risk of thyroid disorder and cardiovascular disease. The age group criteria for these women were 40 to 50 years. Thyroid profile including TSH, T3, and T4 were estimated by using enzyme linked immunesorbent assay. Serum levels of 25(OH) D3 was estimated by using spectrophotometric method. Lipid profile including TC, TG and HDL-C were estimated CHOD-POD method, GPO-PAP method, and CHOD-POD/Phosphotungustate method. LDL-C was calculated by friedewald formula.Results: There 58 women were presented with insufficient amount of vitamin D. They were characterised with increased BMI, elevated thyrotropin alongwith lower concentrations of T3 and T4. Increased levels of TC, TG and LDL-cholesterol alongwith lower concentration of HDL-C were also observed in women with vitamin d deficiency. Women having vitamin D deficiency were presented with overweight (OR-18.0, p-value=<0.001) and dyslipidemia (OR-12.13, p-value≤0.001). Vitamin D was negatively correlated with variable i.e. BMI, TSH, TC, TG and LDL-C. This negative association was significant (<0.001) while HDL-C and T4 were positively correlated with vitamin D levels in this study population.Conclusions: Vitamin D deficiency frequently occurs in middle aged perimenopausal women. Negative correlation of it with BMI, TSH and lipid variables may suggest the development of cardiovascular disease and hypothyroidism in coming years. Vitamin D supplements or vitamin D containing diet and regular exposure to sun is highly recommended to perimenopausal women.

OBJECTIVEVitamin D deficiency has been associated with a variety of negative outcomes in critically ill patients, but little focused study on the effects of hypovitaminosis D has been performed in the neurocritical care population. In this study, the authors examined the effect of vitamin D deficiency on 3-month outcomes after discharge from a neurocritical care unit (NCCU).METHODSThe authors prospectively analyzed 25-hydroxy vitamin D levels in patients admitted to the NCCU of a quaternary care center over a 6-month period. Glasgow Outcome Scale (GOS) scores were used to evaluate their 3-month outcome, and univariate and multivariate logistic regression was used to evaluate the effects of vitamin D deficiency.RESULTSFour hundred ninety-seven patients met the inclusion criteria. In the binomial logistic regression model, patients without vitamin D deficiency (> 20 ng/dl) were significantly more likely to have a 3-month GOS score of 4 or 5 than those who were vitamin D deficient (OR 1.768 [95% CI 1.095–2.852]). Patients with a higher Simplified Acute Physiology Score (SAPS II) (OR 0.925 [95% CI 0.910–0.940]) and those admitted for stroke (OR 0.409 [95% CI 0.209–0.803]) or those with an “other” diagnosis (OR 0.409 [95% CI 0.217–0.772]) were significantly more likely to have a 3-month GOS score of 3 or less.CONCLUSIONSVitamin D deficiency is associated with worse 3-month postdischarge GOS scores in patients admitted to an NCCU. Additional study is needed to determine the role of vitamin D supplementation in the NCCU population.

The Impact

Abstract Background To investigate the impact and underlying mechanisms of vitamin-D-deficiency (VDD) on outcome of elderly (61 to 80 year-old) DLBCL patients. Methods Pretreatment 25-OH-vitamin-D serum levels from 359 patients treated in the prospective multicenter RICOVER-60 trial with 6 or 8 cycles of CHOP-14 with and without 8 cycles rituximab and 63 patients in the RICOVER-noRT study treated with 6xCHOP-14 + 8xR were determined determined by LIASION®, a commercially available chemoluminescent immunoassay. Results RICOVER-60 patients with VDD (defined as serum levels ≤8 ng/m l) and treated with rituximab had a 3-year event-free survival of 59% compared to 79% in patients with >8 ng/ml; 3-year overall survival was 70% and 82%, respectively. These differences were significant in a multivariable analysis adjusting for IPI risk factors with a hazard ratio of 2.1 [p=0.008] for event-free survival and 1.9 [p=0.040] for overall survival. In patients treated without rituximab 3-year EFS was not significantly different in patients with vitamin-D levels ≤8 and >8 ng/ml (HR 1.2; p=0.388). These results were confirmed in an independent validation set of 63 patients treated within the RICOVER-noRT study. Rituximab-mediated cellular toxicity (RMCC) against the CD20+ cell line Daudi as determined by LDH release assay increased significantly (p<0.005) in 5/5 vitamin-D-deficient individuals after vitamin-D substitution and normalization of their vitamin-D levels. Conclusions VDD is a significant risk factor for elderly DLBCL patients treated with rituximab. Our results show that VDD impairs RMCC and that RMCC can be improved by vitamin-D substitution. This together with the differential effect of VDD in patients treated with and without rituximab suggests that vitamin-D substitution might result in a better outcome of these patients when treated with CHOP plus rituximab.

8569 Background: Vitamin D deficiency was shown to be is associated with a worse outcome in patients with non-Hodgkin's lymphoma (Drake et al., 2010) To study whether this observation could be confirmed in patients with aggressive B-cell lymphomas treated uniformly within a prospective trial, we analyzed 25-OH vitamin D serum levels in patients treated within the RICOVER-60 trial of the DSHNHL. Methods: 25-OH Vitamin D serum levels were determined with a commercial chemoluminescence immunoassay in the serum from elderly patients of the RICOVER-60 trial which compared 6 or 8 cycles of CHOP, both with and without rituximab. Results: 193 of 359 pts (53.8%) had vitamin D deficiency (<10 ng/ml) and 165/359 patients (46.0%) had vitamin D insufficiency (10-30 ng/ml) according to current definitions. When treated with R-CHOP, patients with vitamin D levels ≤8 ng/ml had a 3-year EFS of 59% compared to 79% of patients with vitamin D serum levels >8 ng/ml; the respective figures for 3-year overall survival were 70% and 82%, respectively. In R-CHOP pts these differences were significant in a multivariable analysis adjusting for IPI risk factors with a hazard ratio (HR) of 2.1 (p=0.008) for EFS and a HR of 1.9 (p=0.040) for OS. In pts treated without R effects of vitamin D deficiency were significant only for OS (HR 1.8; p=0.025), but not with respect to EFS (HR 1.2; p=0.388). These results were confirmed in an independent validation set of 63 patients treated within the prospective RICOVER-noRx study. Conclusions: Vitamin D deficiency is a significant risk factor for patients with aggressive B-cell lymphomas treated with R-CHOP. The stronger adverse effect of vitamin D deficiency in patients receiving rituximab suggests that vitamin D deficiency interferes with the R mechanisms of this antibody. A prospective study evaluating the effects of vitamin D substitution on outcome of patients receiving R-CHOP is warranted. Supported by Deutsche Krebshilfe.

Vitamin D is essential for calcium absorption and for maintaining bone health in the pediatric population. We conducted a retrospective study to establish the profile of a child aged under 3 years old with vitamin D deficiency in the context of correct prophylaxis, on a cohort of 49 children from two general practitioner offices. From the study group 30.6% of children (15 cases) had low vitamin D levels. The mean serum 25(OH)D level was 41.5±16.6 ng/ml. Regarding nutrition in the first year of life, breastfeeding predominated (83.7% of patients), and only 8.16% of patients had clinical signs of rickets. So, low serum levels of vitamin D can also be found in children who have successfully received correct prophylaxis with vitamin D. Keywords: vitamin D, children, rickets

Deep neck infection (DNI) refers to infections in spaces created by superficial and deep cervical fascia around the muscles and organs in the neck. Vitamin D is highly important for an effective immune system. Vitamin D receptors (VDR) have been identified in immune system cells, and particularly in T and B lymphocytes, macrophages, and dendritic cells. Vitamin D deficiency is thought to result in impaired immune response, decreased leukocyte chemotaxis, and an increased disposition to infection. The purpose of this study was to investigate whether vitamin D deficiency is an underlying occult factor in the development of DNI. Sixty-five patients aged 6 to 90, diagnosed with DNI, and 70 healthy age- and sex-compatible cases were included in the study. Serum levels of calcium, phosphorus, parathyroid hormone, and 25-hydroxy vitamin D (25(OH)D) were determined in each case. 25-hydroxy vitamin D levels above 20 ng/mL were regarded as normal, 12 to 20 ng/mL as insufficient, 5 to 12 ng/mL as deficient, and less than 5 ng/mL as severely deficient. Mean serum 25(OH)D levels were 10.4 (6.2) ng/mL in the patient group and 15.5 (6.4) ng/mL in the control group ( P < .01). This difference was statistically significant ( P < .01). Vitamin D was within normal limits in 9.2% (n = 6) of cases in the study group, insufficient in 29.2% (n = 19), deficient in 35.3% (n = 23), and severely deficient in 26.2% (n = 17). The equivalent values in the control group were 21.4% (n = 15), 48.5% (n = 34), 30% (n = 21), and 0% (n = 0). Serum 25(OH)D levels were significantly lower in patients with DNI compared to the healthy cases; 25(OH)D levels may be a factor in the development of DNI.

Abstract. Vitamin D deficiency is associated with several non-homeostatic conditions and/or diseases like inflammation, atherosclerosis, cardiovascular disease and mortality. YKL-40 is a glycoprotein, secreted by macrophages, neutrophils and different cell types and it is also associated with inflammation and pathological tissue remodeling. In this study, we aimed to evaluate relationship between the proinflammatory biomarkers YKL-40 and hs-CRP levels and vitamin D deficiency. Our study group includes 45 subjects with vitamin D deficiency (Group 1) (20 M, 25 F; mean age 37.72 ± 7.70 years) and 40 age and sex-matched healthy subjects with normal serum levels of vitamin D (Group 2) (19 M, 21 F; mean age 39.26 ± 7.41 years). Plasma 25 (OH) vitamin D levels were measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Plasma YKL-40 analysis was performed by ELISA. Serum hs-CRP levels were measured by nephelometric method. Plasma vitamin D levels below 20 ng/mL were accepted as vitamin D deficiency. Although we could not find any significant differences by means of serum hs-CRP levels between Group 1 and Group 2 (2.21 (0.27–11.70); 1.79 (0.16–9.85) mg/L, p = 0.247), plasma YKL-40 levels were significantly higher in group 1 than group2 (70.47 (17.84–198.50); 47.14 (4.80–135.48) ng/mL, p = 0.047). In literature, vitamin D deficiency is associated with inflammation. In our study, we found similar hs-CRP levels between groups and higher YKL-40 levels in group 1. Vitamin D deficiency may be related to high YKL-40 levels in terms of causing chronic inflammation.
