Abstract
Vitamin D-binding protein (DBP), also known as Gc-globulin, is a protein that affects several physiological processes, including the transport and regulation of vitamin D metabolites. Genetic polymorphisms in the DBP gene have a significant impact on vitamin D levels and may have implications for disease risk. DBP polymorphisms are linked to differential immune responses, which could influence the onset of juvenile diseases. This narrative review examines the various roles of DBP, with a focus on bone health, immunological regulation, and lipid metabolism in children. Chronic disorders affected by DBP polymorphisms include bone abnormalities, autoimmune diseases, cardiovascular issues, childhood asthma, allergies, cystic fibrosis, acute liver failure, celiac disease, inflammatory bowel disease, and chronic kidney disease. Future research should focus on identifying the processes that underpin the many roles that DBP plays and developing customized therapeutics to improve health outcomes in the juvenile population.

Ju F, Zhu R. Association of vitamin D levels and VDR variant (rs2228570) with allergic rhinitis: A meta-analysis and trial sequential analysis. Heliyon 2023; 9:e17283. [PMID: 37426797 PMCID: PMC10329122 DOI: 10.1016/j.heliyon.2023.e17283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Revised: 06/12/2023] [Accepted: 06/13/2023] [Indexed: 07/11/2023] Open
Abstract
Background Allergic rhinitis (AR) is a most common allergic condition characterised by cough, sneezing and flu-like symptoms. The aetiology of AR is not known. A deficiency of vitamin D has been associated with various allergic diseases. The role of vitamin D in allergic rhinitis has been explored in different populations, but the results remained inconsistent. Furthermore, vitamin D exerts its effect through the vitamin D receptor (VDR), and genetic variations in the VDR gene significantly alter vitamin D. We performed a meta-analysis to investigate the role of vitamin D levels and VDR polymorphisms with a predisposition to the development of AR. Materials and methods All published articles were searched using databases such as PubMed, Google Scholar, and Science Direct. Based on rigorous inclusion and exclusion, appropriate studies were identified. Vitamin D levels, VDR genotype and allele frequencies were extracted from the eligible reports. The meta-analysis was performed by comprehensive meta-analysis software v3.3. Results The present meta-analysis comprised 14 reports with 1504 AR patients and 1435 healthy controls. Compared to healthy controls, AR had significantly lower levels of vitamin D (P = 0.000, standard difference of means = -1.287, 95% CI = -1.921 to -0.652). The meta-analysis of two separate investigations, which included 917 cases and 847 controls, showed no predisposition to allergic rhinitis. The trial sequential analysis also demonstrated the need for future case-control studies of VDR polymorphism to examine their involvement in AR. Conclusions Lower vitamin D levels are associated with allergic rhinitis, and vitamin D supplementation might be advantageous in addition to standard treatment. The connection of VDR polymorphism (rs2228570) remained equivocal, and additional research is needed. Summary Vitamin D exerct its beneficial effect through the vitamin D receptor (VDR) and role of vitamin D and VDR variant in the allergic rhinitis has been contradictories. We performed a meta-analysis to draw a definitive conclusion of importance of vitamin D and VDR polymorphisms in predisposition to development of allergic rhinitis. The observations of the meta-analysis revealed a significant association of lower vitamin D with allergic rhinitis. In addition the VDR rs2228570 variant predisposed subject to develop rhinitis. Collectively, the results of the present investigation redirect requirement of individualized vitamin D supplementation in the management of allergic rhinitis.

Association of food allergy in children with vitamin D insufficiency: a systematic review and meta-analysis. Eur J Pediatr 2023; 182:1533-1554. [PMID: 36790484 DOI: 10.1007/s00431-023-04843-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 01/16/2023] [Accepted: 01/23/2023] [Indexed: 02/16/2023]
Abstract
Current literature regarding the association of vitamin D insufficiency and food allergy is contradicting. The purpose of our study was to investigate this association. This is a systematic review and meta-analysis according to the PRISMA statement. PubMeD and Scopus databases were systematically searched for case-control studies investigating the association between pediatric food allergy and vitamin D insufficiency. Our search yielded 806 studies. Ten final studies were considered eligible for qualitative and quantitative analysis. Children with vitamin D insufficiency were found to have 68% more probability to present a food allergy episode (adjusted pooled OR: 1.68, 95% CI [1.25-2.27], p-value: 0.001). In their second year of life they were 4 times more likely to present a food allergy episode (adjusted pooled OR: 4.06, 95% CI [1.93-8.56], p-value: < 0.001), and 56% more probable to develop food sensitization (OR: 1.56, 95% CI [1.15-2.11], p-value: < 0.004). Children in Australia with vitamin D insufficiency were almost 4 times more likely to develop egg sensitization (adjusted OR: 3.79, 95% CI [1.19-12.08], p-value: 0.024). Children with vitamin D insufficiency were almost twice as likely to have peanut sensitization (OR: 1.96, 95% CI [1.08-3.57], p-value: 0.028). Conclusion: Decreased maternal vitamin D levels and infant vitamin D insufficiency appear to increase the incidence of food allergies, particularly in the second year of life. To confirm this association, multicenter longitudinal studies are required. What is Known: • In newborns and young children, vitamin D deficiency and insufficiency are prevalent. • The exact role of vitamin D in atopic diseases remains controversial. What is New: • Decreased maternal vitamin D levels and infant vitamin D insufficiency appear to increase the incidence of food allergies. This association is more evident in the second year of life.

[PMID: 36999126 PMCID: PMC10046179 DOI: 10.2147/idr.s403482] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 03/06/2023] [Indexed: 04/01/2023] Open
Abstract
Purpose Severe Fever with Thrombocytopenia Syndrome (SFTS) is an infectious disease with rapid onset and high case fatality rate. The study was to explore the clinical value by examining the serum level of 25-hydroxyvitamin D (25 (OH) D) in SFTS patients. Methods One hundred and five patients and 156 healthy controls were included. Univariate and multivariate regression analyses were performed to identify independent risk factors for disease progression. Subject operating characteristics (ROC) curves were drawn, and the corresponding area under the curve (AUC) was calculated to assess the sensitivity and specificity of the diagnostic disease. Results The 25 (OH) D level of disease group was lower than that of healthy control group (22.12 (18.43, 25.86) ng/mL vs 27.36 (23.20, 32.71) ng/mL; P<0.05). The 25 (OH) D level of severe disease group was lower than that of mild disease group (20.55(16.30, 24.44) ng/mL vs 24.94(20.89, 31.91) ng/mL; P<0.05). And there was no significant difference of 25 (OH) D level between the survival group and death group in severe disease group. Multivariate Logistic regression analysis showed that the 25 (OH) D level under 19.665 ng/mL was an independent risk factor for the development of SFTS (OR = 0.901, P=0.040). Furthermore, age more than 68.5 years old and lactate dehydrogenase (LDH) more than 1023.5U/L were independent risk factors for death in severe patients with SFTS. Conclusion Patients with SFTS have reduced 25 (OH) D level, and 25 (OH) D is a risk factor for disease severity in patients with SFTS. Vitamin D supplementation may be an effective measure to reduce the risk of infection and improve the prognosis.

Abstract
BACKGROUND Allergic rhinitis is a frequent disorder during pregnancy, while in children it is triggered by significantly lower serum vitamin E level. This research aimed to investigate whether serum vitamin E level exhibited clinical significance in pregnant women with allergic rhinitis. METHODS In this study, 37 pregnant women with allergic rhinitis and 35 healthy pregnant women were recruited. Allergic rhinitis severity was analyzed by the Total Nasal Symptom Score (TNSS) questionnaire. Blood samples were collected to evaluate serum vitamin E, interleukin (IL), and total IgE levels. RESULTS In pregnant women with allergic rhinitis, serum level of vitamin E was significantly lower than in healthy pregnant women. Serum vitamin E level in pregnant women with allergic rhinitis showed a negative correlation with TNSS, IL-13, IL-4, and total IgE levels. CONCLUSION In conclusion, this research has demonstrated that pregnant women with allergic rhinitis showed significantly lower serum level of vitamin E. The decreased vitamin E showed a correlation with the pathogenesis of allergic rhinitis in pregnant women.

Abstract
OBJECTIVE This article summarizes the research progress on the association of vitamin D and food allergy in infants and children. BACKGROUND In recent years, food allergy seriously has affected the quality of life of children and adults. Vitamin D is known to be involved in calcium and phosphorus metabolism, and recent research has demonstrated that vitamin D can also affect the immune regulation of food allergy. METHODS The present study summarizes the research progress on the association of vitamin D and food allergy in infants and children. We searched the PubMed database to identify studies on the association of vitamin D and food allergy published between January 2003 and August 2021. CONCLUSIONS Vitamin D in the body through a number of steps into the final formation of biological effects. The implications of postnatal vitamin D levels for food allergy may be even greater. Vitamin D can prevent the intestinal immune system from being exposed to allergens by maintaining the integrity of the mucosal barrier. Many clinical studies believe that vitamin D supplementation can improve infants' and children's food allergy, however, some show negative results or opposite results. A lot of laboratory studies have confirmed that vitamin D is involved in the immune regulation of food allergy. Evidence indicates there may be a nonlinear relationship between vitamin D and food allergy. Further researches need to be launched.

Abstract
Introduction Allergic rhinitis (AR) is the most common non-infectious rhinitis and is associated with sneezing, cough, and flu-like symptoms. The exact pathophysiology of AR remains uncertain. The deficiency of vitamin D3 has been documented as a probable cause of allergic conditions due to its role in immunomodulation. The aim of this study was to evaluate the role of vitamin D3 deficiency in allergic rhinitis. Methods This case-control study was conducted with 50 patients of AR and 50 healthy individuals. Serum immunoglobulin (Ig) E and vitamin D3 levels were measured in all study participants. Data were analyzed using SPSS v. 21.0 (IBM Corp., Armonk, NY). Results Mean serum IgE levels in the AR group were 553.5 ± 53.9 IU/L as compared to 219.4 ± 32.1 IU/L in the control group (p <0.0001). AR patients had mean serum vitamin D levels of 14.8 ± 7.4 ng/mL as compared to 19.1 ± 6.6 ng/mL in the control group (p=0.002). Only 10% of participants in the AR group had adequate serum vitamin D levels as compared to 26% in the controls (p=0.08). Conclusion Vitamin D deficiency was present in both study groups. The AR group had significantly lower mean levels of serum vitamin D than the control group. However, upon stratification, the differences were insignificant.

Abstract
We aimed to clarify the relation between allergic rhinitis and the serum levels of 25-hydroxivitamin D in the adult population. The study group consisted of 86 patients with allergic rhinitis who were diagnosed with the help of history of allergy, positive signs for allergy, blood samples, and positive skin prick tests; while the control group included 43 age- and sex-matched healthy volunteers with negative skin prick tests. The demographic data, medical history, findings in the physical examinations, serum levels of total immunoglobulin E (IgE) and 25-hydroxyvitamin D, and skin prick test results of the groups were noted. A total of 129 patients fulfilling the necessary criteria were enrolled. The median serum 25-hydroxyvitamin D levels in the study group were significantly lower compared to the control group ( P = .014). In the study group, median serum vitamin D levels were significantly higher in men, compared to women ( P = .03). There was a significant negative correlation between IgE and vitamin D levels in the allergic rhinitis group ( P = .028, r = −0.246). This study showed that patients with allergic rhinitis might be more vulnerable to have lower serum levels of vitamin D. Thus, vitamin D supplementation as an adjunctive therapy may be considered in those patients.

Abstract
Obstructive sleep apnoea syndrome (OSAS) is a common disorder of multifactorial pathogenesis and is associated with obesity, diabetes and cardiovascular disease. Vitamin D is a fat-soluble vitamin with an important function in calcium absorption and homeostasis, which is also implicated in several nonskeletal conditions. The prevalence of vitamin D deficiency is increasing worldwide and is associated with similar metabolic disturbances to OSAS. Moreover, recent data suggest that in OSAS patients serum levels of vitamin D are lower compared with non-apnoeic subjects. However, the mechanisms linking vitamin D deficiency and OSAS are not completely understood and several hypotheses have been advanced. To date, a limited number of studies have assessed the association between lower serum concentrations of vitamin D and OSAS, and have reported inconsistent results. Similarly, contradictory results have been produced by studies which evaluated the effect of continuous positive airway pressure treatment on serum vitamin D levels. The aim of this review is to summarise current knowledge on the association between OSAS and vitamin D levels. Due to multiple confounding factors, vitamin D deficiency is common among sleep apnoea patients; thus, screening should be performed when clinically indicatedhttp://ow.ly/L3ow30krmol

Abstract
BACKGROUND Allergic diseases and vitamin D deficiency were found to have a relationship. However, there was limited number of studies on the relationship between vitamin D with allergic rhinitis (AR) and total nasal symptom scores (TNSS), particularly in determining the cut-off points of serum vitamin D levels which correlated to AR. AIM As this particular study has never been conducted in Indonesia, the main objective of this study was to investigate this issue. METHODS The research was conducted at Dr Soetomo Hospital, Surabaya in January 2017. A group of 30 subjects were recruited using consecutive sampling. Levels of serum vitamin D were measured using electrochemiluminescence immunoassay (ECLIA) method while the total nasal symptom scores were obtained by accumulating all the nasal symptoms. Data of serum vitamin D levels and TNSS were analysed statistically with the Pearson correlation test. RESULTS It was found that the mean of serum 25(OH) vitamin D levels (9.13 ng/mL) of the AR group was significantly lower than the non-AR group (26.22 ng/mL) (P = 0.000). The vitamin D cut-off points which correlated to AR was about 12.83 ng/mL (sensitivity = 80%; specificity = 100%). A Pearson correlation test found a strong, negative correlation between vitamin D levels and TNSS (P = 0.000; r = -0.800). CONCLUSION There was a strong, negative correlation between serum vitamin D levels with AR and TNSS. The cut-off points of serum vitamin D levels correlated to AR were approximately12.83 ng/mL. Thus, further research needs to be conducted.

Abstract
OBJECTIVE To determine the prevalence and risk factors for suboptimal vitamin D status in Korean adolescents and to assess its relationship with atopic dermatitis (AD) and asthma at a national level. DESIGN This is a cross-sectional study with data from the Korean National Health and Nutrition Examination Survey. Information regarding socioeconomic characteristics, clinical data and environmental factors was collected. Blood and urine samples were taken for vitamin D and cotinine, respectively. Descriptive and multivariable logistic regression was performed on the data. SETTING South Korea (nationwide). PARTICIPANTS 2515 individuals aged 10-18 years who participated in the Korean National Health and Nutrition Examination Survey from 2008 to 2011. MAIN OUTCOME MEASURES Vitamin D status was determined through measurement of serum 25-hydroxyvitamin D (25OHD). Smoking status was classified based on the urine cotinine level. Physician diagnosed with AD and asthma were assessed using a questionnaire. RESULTS Overall, 73.3% of the subjects were vitamin D deficient (25OHD <20 ng/mL) and 24.4% of the subjects were vitamin D insufficient (25OHD, 20-29.9 ng/mL). Older age (p<0.001), female gender (p<0.001), urban residence (p=0.019), higher body mass index (p=0.003) and sampling in winter months (November-March) (p<0.001) were independently associated with low serum 25OHD levels. With cotinine verification, 18.2% of the participants were classified as active smokers, and 43.4% were classified as passive smokers. After adjusting for potential confounders, serum 25OHD status showed no association with AD or asthma. CONCLUSION Vitamin D deficiency is highly prevalent in Korean adolescents. Cotinine-verified prevalence of smoking was also high, but its relationship with vitamin D deficiency was not confirmed in our study. Above all, our results provide epidemiological evidence against the association of vitamin D status with AD and asthma at the national level among Korean adolescents.
