Non-association between low vitamin d levels and aeroallergen-positivity evaluated using multiple allergen simultaneous test in Korean adults

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.

Vitamin D Levels

Abstract Purpose Many smaller studies have previously shown a significant association between thyroid autoantibody induced hypothyroidism and lower serum vitamin D levels. However, these finding have not been confirmed by large-scale studies. In this study, we evaluated the relationship between hypothyroidism and vitamin D levels using a large population-based data. Methods For this study, we used National Health and Nutrition Examination Survey (NHANES) during the years 2007–2012. We categorized participants into three clinically relevant categories based on vitamin D levels: optimal, intermediate and deficient. Participants were also split into hypothyroid and hyperthyroid. Weighted multivariable logistic regression analyses were used to calculate the odds of being hypothyroid based on vitamin D status. Results A total of 7943 participants were included in this study, of which 614 (7.7%) were having hypothyroidism. Nearly 25.6% of hypothyroid patients had vitamin D deficiency, compared to 20.6% among normal controls. Adjusted logistic regression analyses showed that the odds of developing hypothyroidism were significantly higher among patients with intermediate (adjusted odds ratio [aOR], 1.7, 95% CI: 1.5–1.8) and deficient levels of vitamin D (aOR, 1.6, 95% CI: 1.4–1.9). Conclusion Low vitamin D levels are associated with autoimmune hypothyroidism. Healthcare initiatives such as mass vitamin D deficiency screening among at-risk population could significantly decrease the risk for hypothyroidism in the long-term.

Vitamin D Levels

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.

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.

Introduction: Vitamin D deficiency is highly prevalent during pregnancy and in premature infants. This study was done to investigate the maternal and infantile levels of vitamin D in preterm infants. Methods: Using available sampling during 2018-2020 the maternal and umbilical cord serum levels of vitamin D were measured in 294 premature infants in Ghaem Hospital, Mashhad, Iran. A researcher-made questionnaire containing neonatal demographic and clinical characteristics was used as data collection tool. Both maternal and placental vitamin D levels were categorized into four classes: severe deficiency (vitamin D<10 ng/ml), moderate deficiency (10.1≤vitamin D≤20 ng/ml), mild deficiency (20.1≤vitamin D≤30 ng/ml) and normal (vitamin D >30.1ng ml). Results: Vitamin D deficiency was seen in 89% of premature infants (46.6% severe, 30.6% moderate, and 11.9% mild). Serum levels of vitamin D were 18.28±13.94 ng/ml and 14.10±9.70 ng/ml in mothers and infants, respectively. The infants below and above 32 weeks had vitamin D values of: 10.97±6.31 ng/ml and 18.05±11.64 ng/ml, respectively. The difference in vitamin D levels between boys (12.59±8.40 ng/ml) and girls (16.05±11.45 ng/ml) was significant (P=0.009). Moderate and severe vitamin D deficiency were more common at earlier pregnancy ages (P=0.001). Conclusion: Vitamin D deficiency is more common and severe in preterm infants and their mothers. Controlling vitamin D level during pregnancy, especially in women at risk of preterm labor and preterm infants may help reduce prematurity problems.

Background. Experimental and clinical studies suggest a possible association between vitamin D deficiency and both diabetic retinopathy and maculopathy.Methods. We have performed a cross-sectional study in adults with types 1 and 2 diabetes mellitus. The relationship between the presence and severity of diabetic retinopathy and maculopathy with serum 25-hydroxyvitamin D concentration was evaluated using logistic regression analyses in the presence of demographic and clinical covariates.Results. 657 adults with diabetes were stratified based on retinopathy grading: No Diabetic Retinopathy (39%), Background Diabetic Retinopathy (37%), Preproliferative Diabetic Retinopathy (21%), and Proliferative Diabetic Retinopathy (3%), respectively. There were no differences in serum 25-hydroxyvitamin D concentrations (25(OH)D) between the groups (15.3±9.0versus16.4±10.5versus15.9±10.4versus15.7±8.5 ng/mL,P=NS). Logistic regression analysis demonstrated no statistically significant relationship between the severity of retinopathy and serum 25(OH)D. Furthermore, there was no difference in serum 25(OH)D between those with (n=94, 14%) and those without (n=563, 86%) Diabetic Maculopathy (16.2±10.0versus15.8±9.8,P=NS) and no relationship was demonstrated by logistic regression analyses between the two variables.Conclusions. This study has found no association between serum 25(OH)D and the presence and severity of diabetic retinopathy or maculopathy.

The Mean

Aim: The aim of this study was to compare vitamin D levels between pregnant women with hyperemesis gravidarum before 12 weeks of gestation and healthy pregnant women at similar ages. Methods: Sixty pregnancies with hyperemesis gravidarum and 60 age compatible healthy pregnancies applied to our facility were included in the study. Demographic characteristics, maternal thyroid function tests and 25-Hydroxyvitamin D levels were evaluated. Student t test was used for the variables with normal distribution and Mann-Whitney U test was used to analyze the variables without normal distribution. Results: Only one pregnant woman had normal vitamin D levels (>30ng/ml), whereas 71 patients had deficiency (10-30 ng/ml), and 48 had severe deficiency (<10 ng/ml). The mean vitamin D level of the total 120 pregnancies was 11.9±5.00 ng/ml (9.92±3.67 ng/ml in case group, 13.88±5.38 ng/ml in control group). The mean value of vitamin D was found to be significantly lower in hyperemesis gravidarum. 45% (n=27) of the pregnant women had vitamin D deficiency, whereas 55% (n=33) of them had severe deficiency. Free T3 and T4 levels were significantly higher than the control group, and thyroid-stimulating hormone level was significantly lower. Conclusion: Vitamin D levels of pregnant women with hyperemesis gravidarum were significantly lower. Vitamin D deficiency should be considered in patients with hyperemesis gravidarum.

Regression Analyses

Vitamin D deficiency has been associated with both type 2 diabetes mellitus (T2DM) and autoimmune disorders. The association of vitamin D with T2DM and thyroid autoimmunity (TAI) has not been investigated. Thus, we aimed to explore the putative association between T2DM and thyroid autoimmunity (TAI) focusing on the role of 25-hydroxy-vitamin D (25(OH)D). Study population included 264 T2DM patients and 234 controls. To explore the potential association between 25(OH)D and thyroid autoimmunity while controlling for potential confounders—namely, age, gender, body mass index, and presence of T2DM—multivariate logistic regression analyses were undertaken. Patients with T2DM were younger (P<0.001) and had significantly lower 25(OH)D levels (P<0.001) and higher anti-TPO titers (P=0.005). Multivariable logistic regression analyses suggested that T2DM and 25(OH)D levels were significantly associated with the presence of thyroid autoimmunity. In an elderly population of diabetic patients and controls with a high prevalence of vitamin D deficiency/insufficiency, a patient with T2DM was found to be 2.5 times more likely to have thyroid autoimmunity compared to a nondiabetic individual and the higher the serum 25(OH)D levels were, the higher this chance was.

AbstractVitamin D deficiency (VDD) has been associated with severe adverse health outcomes during pregnancy is increasingly recognised as a public health concern and maternal and infant VDD is closely associated. The aim of this study was to evaluate the magnitude of VDD and associated factors in pregnant women and newborns in the postpartum period. A cross-sectional study was carried out in a total of 66 pregnant women at > 37 weeks of gestation and newborns at the Gaziantep University Faculty of Medicine, Department of Obstetrics and Gynecology in Gaziantep, Turkey. Demographic characteristics, 24-h dietary recalls, intake of food supplements were determined in pregnant women, maternal and newborn anthropometric measurements and serum (25-OHD) levels were assessed. Mean age (± SD) of pregnant women was 28.8 ± 6.9 years. Although Turkey has “National Vitamin D Supplementation Programme for Pregnant Women” only 33.3% of women had VD supplementation during pregnancy, not all in the recommended levels (1200 IU/day). Mean (± SD) serum 25(OH)D levels in pregnant women and cord blood of newborns were 17.3 ± 9.0 ng/mL [non-supplemented women (NSW): 16.5 ± 7.9 ng/mL; supplemented women (SW): 18.8 ± 11.0 ng/mL] and 16.6 ± 9.9 ng/mL [newborns of non-supplemented women (NNSW): 13.9 ± 8.7 ng/mL and newborns of supplemented women (NSW): 22.1 ± 10.1 ng/mL], respectively. Vitamin D severe deficiency (< 10 ng/dL) was noted in 22.7%, deficiency (11–19 ng/mL) 51.5%, insufficiency (20–29 ng/mL) 15.2% and sufficiency (≥ 30 ng/mL) 10.6% of the women whereas severe deficiency, deficiency, insufficiency and sufficiency respectively, were determined in 33.3%, 39.5%, 13.6% and 13.6% of newborns (NNSW vs NSW, p = 006, p < 0.05). Median serum VD levels of NSW were statistically higher than NNSW (p = 0.000, p < 0.05). Out of total, 86.4% of women were dressing traditionally covered, and had lower serum VD level (p = 0.049, p > 0.05). SW had higher median body weight (p = 0.026) and body mass index (BMI) (p = 0.036) levels than NSW (p < 0.05). No statistically significant differences were found between anthropometric measurements of NNSW and NSW groups, although birth weights of NNSW and NSW groups were determined as 3005.1 ± 456.1 g and 3153 ± 422.5 g (p > 0.05), respectively. Maternal serum vitamin D levels strongly were correlated with newborn levels. Maternal vitamin D deficiency is a great problem and “National Vitamin D Supplementation Programme for Pregnant Women and Infants” should be effectively implemented and monitored. Also fortification programme should be a national policy.
