Abstract
INTRODUCTION This study evaluated nutrient deficiencies in infants and toddlers with inflammatory bowel disease (IBD) and eosinophilic gastrointestinal disorders (EGIDs), whose primary nutritional source is elemental formulas (EFs). METHODS The nutrient status of children with IBD and EGID aged 6 months to 6 years was evaluated. RESULTS Twenty-one children fed with EFs (EF group) and 25 controls (CL group) were enrolled. The selenium level in the EF group was lower than that in the CL group (2.2 μg/dL vs. 9.3 μg/dL; p < 0.01). Although fat-soluble vitamins were deficient in some EF group participants, no significant differences were observed in their concentration and insufficiency proportion. However, ascorbic acid deficiency was more frequent in the EF group, with significantly lower levels (8.6 μg/mL vs. 12.0 μg/mL; p < 0.01). The triene:tetraene ratio was significantly higher in the EF group (0.046 vs. 0.010; p < 0.01). Asparagine and taurine levels were significantly lower in the EF group (asparagine: p < 0.01; taurine: p < 0.01) and tyrosine and phenylalanine levels were higher in the EF group, resulting in a lower Fisher's ratio (p < 0.01). CONCLUSION Long-term feeding with EFs can cause deficiencies in essential fatty acids, selenium, and ascorbic acid and also carries a risk of amino acid imbalance in infants and toddlers.

Maternal Age at Menarche Genes Determines Fetal Growth Restriction Risk. Int J Mol Sci 2024; 25:2647. [PMID: 38473894 PMCID: PMC10932237 DOI: 10.3390/ijms25052647] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 02/06/2024] [Accepted: 02/14/2024] [Indexed: 03/14/2024] Open
Abstract
We aimed to explore the potential link of maternal age at menarche (mAAM) gene polymorphisms with risk of the fetal growth restriction (FGR). This case (FGR)-control (FGR free) study included 904 women (273 FGR and 631 control) in the third trimester of gestation examined/treated in the Departments of Obstetrics. For single nucleotide polymorphism (SNP) multiplex genotyping, 50 candidate loci of mAAM were chosen. The relationship of mAAM SNPs and FGR was appreciated by regression procedures (logistic/model-based multifactor dimensionality reduction [MB-MDR]) with subsequent in silico assessment of the assumed functionality pithy of FGR-related loci. Three mAAM-appertain loci were FGR-linked to genes such as KISS1 (rs7538038) (effect allele G-odds ratio (OR)allelic = 0.63/pperm = 0.0003; ORadditive = 0.61/pperm = 0.001; ORdominant = 0.56/pperm = 0.001), NKX2-1 (rs999460) (effect allele A-ORallelic = 1.37/pperm = 0.003; ORadditive = 1.45/pperm = 0.002; ORrecessive = 2.41/pperm = 0.0002), GPRC5B (rs12444979) (effect allele T-ORallelic = 1.67/pperm = 0.0003; ORdominant = 1.59/pperm = 0.011; ORadditive = 1.56/pperm = 0.009). The haplotype ACA FSHB gene (rs555621*rs11031010*rs1782507) was FRG-correlated (OR = 0.71/pperm = 0.05). Ten FGR-implicated interworking models were founded for 13 SNPs (pperm ≤ 0.001). The rs999460 NKX2-1 and rs12444979 GPRC5B interplays significantly influenced the FGR risk (these SNPs were present in 50% of models). FGR-related mAAM-appertain 15 polymorphic variants and 350 linked SNPs were functionally momentous in relation to 39 genes participating in the regulation of hormone levels, the ovulation cycle process, male gonad development and vitamin D metabolism. Thus, this study showed, for the first time, that the mAAM-appertain genes determine FGR risk.

Abstract
In this study, the association between maternal age at menarche (AAM)-related polymorphisms and offspring birth weight (BW) was studied. The work was performed on a sample of 716 pregnant women and their newborns. All pregnant women underwent genotyping of 50 SNPs of AAM candidate genes. Regression methods (linear and Model-Based Multifactor Dimensionality Reduction (MB-MDR)) with permutation procedures (the indicator pperm was calculated) were used to identify the correlation between SNPs and newborn weight (transformed BW values were analyzed) and in silico bioinformatic examination was applied to assess the intended functionality of BW-associated loci. Four AAM-related genetic variants were BW-associated including genes such as POMC (rs7589318) (βadditive = 0.202/pperm = 0.015), KDM3B (rs757647) (βrecessive = 0.323/pperm = 0.005), INHBA (rs1079866) (βadditive = 0.110/pperm = 0.014) and NKX2-1 (rs999460) (βrecessive = -0.176/pperm = 0.015). Ten BW-significant models of interSNPs interactions (pperm ≤ 0.001) were identified for 20 polymorphisms. SNPs rs7538038 KISS1, rs713586 RBJ, rs12324955 FTO and rs713586 RBJ-rs12324955 FTO two-locus interaction were included in the largest number of BW-associated models (30% models each). BW-associated AAM-linked 22 SNPs and 350 proxy loci were functionally related to 49 genes relevant to pathways such as the hormone biosynthesis/process and female/male gonad development. In conclusion, maternal AMM-related genes polymorphism is associated with the offspring BW.

Impact of daily vitamin D 3 supplementation on the risk of vitamin D deficiency with the interaction of rs2282679 in vitamin D binding protein gene (GC) among overweight and obese children and adolescents: A one-year randomized controlled trial. Front Nutr 2022; 9:1061496. [PMID: 36579074 PMCID: PMC9792175 DOI: 10.3389/fnut.2022.1061496] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Accepted: 11/11/2022] [Indexed: 12/14/2022] Open
Abstract
Background The rs2282679 polymorphism in the vitamin D binding protein (DBP) gene may influence the response to vitamin D supplementation. Therefore, we examine the effect of 1-year vitamin D supplementation on vitamin D deficiency (VDD) with the interaction of rs2282679 polymorphism in overweight and obese children and adolescents. Materials and methods The participants (n = 300) were part of a randomized controlled trial who received a daily supplement of either 1,000 or 2,000 IU or four supplements of 1,000 IU weekly (equal to 600 IU daily) of vitamin D3 for 12 months. Genotyping was performed using amplification refractory mutation system polymerase chain reaction (ARMS-PCR). Results The mean of 25(OH)D values at baseline for participants with the TT, TG, and GG genotypes were 15.4, 14.4, and 10.8 ng/mL, respectively, and were not different between the three genotype groups (P = 0.062). A significant reduction in VDD was observed after vitamin D supplementation with dosages of 1,000 or 2,000 IU compared to 600 IU. No significant association of genotypes with risk of VDD was observed in each intervention group after vitamin D supplementation, except, that individuals with TG genotype showed a higher risk of VDD compared to those with TT genotype in the 2,000 IU group after 6 months of supplementation [odds ratio (95% CI): 6.94; 1.30-37.02]. We observed no interaction between time duration, three genotypes, and dosages with serum 25(OH)D, calcium, phosphorus, alkaline phosphatase, and parathyroid hormone levels. Conclusion Response to vitamin D supplementation by three doses of 600, 1,000, and 2,000 IU could not be affected by rs2282679 polymorphism during 12 months in overweight and obese children and adolescents.

Association of VDBP (rs4588 and rs7041) gene polymorphisms with susceptibility to postpartum depression in South Indian population: A cross-sectional study. Psychiatry Res 2022; 316:114713. [PMID: 35878482 DOI: 10.1016/j.psychres.2022.114713] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 07/02/2022] [Accepted: 07/04/2022] [Indexed: 11/18/2022]
Abstract
Low vitamin D levels have been implicated in postpartum depressive disorders (PPD). Our study aimed to demonstrate the association of Vitamin D Binding Protein (VDBP) genetic variants rs7041 and rs4588 with susceptibility to PPD and to investigate their possible relationship with serum vitamin D and VDBP levels in Indian women with PPD. A cross-sectional study involved 330 cases and 330 controls. Depressive symptoms were assessed using Edinburg Postnatal Depression Scale. Genotyping of SNPs was done by Taqman 5'allelic discrimination assay. Estimation of serum 25 hydroxyvitamin D [25(OH) D] and VDBP levels were done by ELISA. Serum total, free and bioavailable 25(OH) D levels were significantly lower in cases compared to controls, with similar levels of VDBP between the two groups. The study results showed that the VDBP rs4588 variant genotype AA was significantly associated with lower circulating levels of total 25(OH) D in cases. Also, the VDBP rs7041 variant TT genotype demonstrated significantly lower levels of total, free and bioavailable 25(OH) D levels in controls. However, VDBP rs7041 and rs4588 variants were not associated with PPD susceptibility. Also, VDBP haplotypes showed no association with PPD susceptibility. Our results demonstrated that VDBP polymorphisms rs4588 and rs7041 and their haplotypes are not associated with PPD susceptibility in the South Indian population. However, vitamin D levels were found to be influenced by the risk genotypes of VDBP SNPs rs4588 and rs7041.

Okazaki N, Ikeda H, Honda T, Tsuno K, Inoue F, Takahashi S, Sakurai A, Ueki H, Noguchi Y, Hamada H, Igarashi S. The impact of vitamin D on the onset and progress of Kawasaki disease. Pediatr Int 2022; 64:e15191. [PMID: 35831250 DOI: 10.1111/ped.15191] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Revised: 02/18/2022] [Accepted: 03/10/2022] [Indexed: 12/01/2022]
Abstract
BACKGROUND The seasonal epidemic of Kawasaki disease (KD) in winter in Japan suggests that low vitamin D status may affect KD through the immune system. We aimed to evaluate the effect of vitamin D on the onset and clinical course of KD. METHODS We conducted a case-control study to compare 25-hydroxyvitamin D (25(OH)D) levels in KD patients admitted to our hospital between March 2018 and June 2021, with those in healthy controls from published Japanese data. In patients with KD, we evaluated the association of 25(OH)D levels with intravenous immunoglobulin resistance and coronary artery lesions. RESULTS We compared 290 controls and 86 age-group-adjusted patients with KD. The 25(OH)D levels in KD patients were lower than those in the controls (median: 17 vs. 29 ng/mL, P < 0.001). In winter, 25(OH)D levels in KD patients were lower than those in summer (median: 13 vs. 19 ng/mL). The adjusted odds ratios for the onset of KD were 4.9 (95% CI: 2.5-9.6) for vitamin D insufficiency (25(OH)D: 12-20 ng/mL) and 29.4 (95% CI: 12.5-78.2) for vitamin D deficiency (25(OH)D < 12 ng/mL). Among 110 KD patients, 25(OH)D levels at diagnosis of KD were not associated with intravenous immunoglobulin resistance or coronary artery lesions. CONCLUSIONS The 25(OH)D levels in patients with KD were lower than those in the controls, especially in winter. Lower 25(OH)D levels in winter were associated with an increased risk of KD onset. It remains to be elucidated whether the observed association has a causal relationship.

Vitamin D-Related Genetics as Predictive Biomarker of Clinical Remission in Adalimumab-Treated Patients Affected by Crohn's Disease: A Pilot Study. Pharmaceuticals (Basel) 2021; 14:1230. [PMID: 34959633 PMCID: PMC8706953 DOI: 10.3390/ph14121230] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 11/18/2021] [Accepted: 11/19/2021] [Indexed: 02/07/2023] Open
Abstract
Adalimumab (ADA) is a human anti-tumor necrosis factor (TNF-α) monoclonal antibody used in inflammatory bowel diseases, such as Crohn's disease (CD). Vitamin-D (VD) is important for biological functions, such as the modulation of expression of genes encoding enzymes and transporters involved in drug metabolism and transport. ADA trough levels were associated with VD concentrations in patients with IBD, but no data are present in the literature concerning VD pathway-related gene single-nucleotide polymorphisms (SNPs) in affecting clinical outcomes. For this reason, the aim of this study was to evaluate the ability of VD-related genetics to predict clinical remission at 3 and 12 months in patients affected by CD treated with ADA. Patients affected by CD were included in this study. SNPs in CYP27B1, CYP24A1, GC, and VDR genes were analyzed through real-time PCR. A total of 63 patients were enrolled. Calprotectin, hemoglobin, and C-reactive protein levels were influenced by SNPs in VDR, CYP27B1, and GC genes. After 3 months of therapy, clinical remission was predicted by smoke, systemic steroids, and VDR BsmI, whereas at 12 months by GC 1296AA/AC and VD supplementation. This study reports the association between VD pathway-related genetics and ADA treatment. Further studies are needed to confirm these promising data.

Abstract
OBJECTIVE The aim of this study was to determine whether a vitamin D genetic risk score (vitDGRS) is associated with 25-hydroxyvitamin D (25(OH)D) level and multiple sclerosis (MS) relapses in children. METHODS DNA samples were typed for single nucleotide polymorphisms (SNPs) from four genes previously identified to be associated with 25(OH)D levels. SNPs with strong associations with 25(OH)D after multiple comparison correction were used to create a genetic risk score (vitDGRS). Cox regression models tested associations of vitDGRS with relapse hazard. RESULTS Two independent SNPs within or near GC and NADSYN1/DHCR7 genes were strongly associated with 25(OH)D levels in the discovery cohort (n = 182) after Bonferroni correction. The vitDGRS of these SNPs explained 4.5% of the variance of 25(OH)D level after adjustment for genetic ancestry. Having the highest versus lowest vitDGRS was associated with 11 ng/mL lower 25(OH)D level (95% confidence interval (CI) = -17.5, -4.5, p = 0.001) in the discovery cohort. Adjusting for ancestry, sex, disease-modifying therapy (DMT), and HLA-DRB1*15 carrier status, the highest versus lowest vitDGRS was associated with 2.6-fold (95% CI = 1.37, 5.03, p = 0.004) and 2.0-fold (95% CI = 0.75, 5.20, p = 0.16) higher relapse hazard in the discovery and replication cohorts, respectively. CONCLUSION The vitDGRS identifies children at greater risk of relapse. These findings support a causal role for vitamin D in MS course.

Distribution of variants in multiple vitamin D-related loci (DHCR7/NADSYN1, GC, CYP2R1, CYP11A1, CYP24A1, VDR, RXRα and RXRγ) vary between European, East-Asian and Sub-Saharan African-ancestry populations. GENES AND NUTRITION 2020; 15:5.

Abstract
BACKGROUND The frequency of vitamin D-associated gene variants appear to reflect changes in long-term ultraviolet B radiation (UVB) environment, indicating interactions exist between the primary determinant of vitamin D status, UVB exposure and genetic disposition. Such interactions could have health implications, where UVB could modulate the impact of vitamin D genetic variants identified as disease risk factors. However, the current understanding of how vitamin D variants differ between populations from disparate UVB environments is limited, with previous work examining a small pool of variants and restricted populations only. METHODS Genotypic data for 46 variants within multiple vitamin D-related loci (DHCR7/NADSYN1, GC, CYP2R1, CYP11A1, CYP27A1, CYP24A1, VDR, RXRα and RXRγ) was collated from 60 sample sets (2633 subjects) with European, East Asian and Sub-Saharan African origin via the NCBI 1000 Genomes Browser and ALFRED (Allele Frequency Database), with the aim to examine for patterns in the distribution of vitamin D-associated variants across these geographic areas. RESULTS The frequency of all examined genetic variants differed between populations of European, East Asian and Sub-Saharan African ancestry. Changes in the distribution of variants in CYP2R1, CYP11A1, CYP24A1, RXRα and RXRγ genes between these populations are novel findings which have not been previously reported. The distribution of several variants reflected changes in the UVB environment of the population's ancestry. However, multiple variants displayed population-specific patterns in frequency that appears not to relate to UVB changes. CONCLUSIONS The reported population differences in vitamin D-related variants provides insight into the extent by which activity of the vitamin D system can differ between cohorts due to genetic variance, with potential consequences for future dietary recommendations and disease outcomes.

Abstract
Due to many biological cell functions of vitamin D including regulation of cell survival, proliferation and differentiation, the metabolism of itself gains importance in the development of several types of cancer. This case-control study was designed to evaluate the risk of gastric cancer development in terms of VDR rs2228570 & rs731236, and VDBP rs7041 polymorphisms, and serum levels of vitamin D. The study consists of 77 gastric cancer patients and 84 healthy individuals. VDR and VDBP gene polymorphisms and vitamin D levels were determined by using PCR-RFLP and HPLC methods. The distribution of VDR or VDBP gene variants were not different in study groups. The serum level of 25-hydroxyvitamin D was significantly lower in gastric cancer patients versus controls (16 ± 6 → 11 ± 6 ng/ml) in which male patients have higher levels than females. Although the whole study population lacks normal levels of 25-hydroxyvitamin D, it was found that the risk of the development of gastric cancer was approximately fourfold higher in cases with severe vitamin D (< 10 ng/ml) deficiency. Our results indicate that VDR rs731236 & rs2228570 or VDBP rs7041 polymorphisms were not risk factors for the development of gastric cancer individually, however, lower serum levels of vitamin D may be a contributory risk for both predisposition and development of gastric cancer.

Abstract
INTRODUCTION Sarcoidosis is a rare multisystem granulomatous disease with unknown etiology. The interplay of vitamin D deficiency and genetic polymorphisms in genes coding for the proteins relevant for metabolism of vitamin D is an important, but unexplored area. The aim of this study was to investigate the association between single nucleotide polymorphisms (SNPs) in CYP2R1 (rs10741657), CYP27B1 (rs10877012), DBP (rs7041; rs4588), and VDR (rs2228570) genes and sarcoidosis, as well as the association between these SNPs and 25(OH)D levels in sarcoidosis patients. MATERIAL AND METHODS For that purpose we genotyped 86 sarcoidosis patients and 50 healthy controls using the PCR-RFLP method. RESULTS Subjects carrying the CC genotype of CYP27B1 rs10877012 have 10 times lower odds of suffering from sarcoidosis. Moreover, DBP rs4588 AA genotype was shown to be a susceptibility factor, where carriers of this genotype had eight times higher odds for developing sarcoidosis. In addition, the A allele of the DBP gene (rs4588) was associated with lower levels of 25(OH)D in sarcoidosis patients. CONCLUSIONS These results suggest that patients with vitamin D deficiency should be regularly tested for genetic modifiers that are related to sarcoidosis in order to prevent development of serious forms of sarcoidosis.

Abstract
Aim Although the relationship between 25-hydroxy (25-OH) vitamin D and asthma is known, it is unknown if 25-OH vitamin D levels are correlated with asthma severity in pediatric patients. The aim of this study was to compare the blood 25-OH vitamin D levels of asthma patients and healthy control groups and to evaluate any correlation between asthma severity and blood 25-OH vitamin D levels in pediatric asthma patients. Methods This is a cross-sectional study which shows the 25-OH vitamin D levels of asthma patients and compared to healthy controls followed by a tertiary pediatric clinic. We investigated the effect of 25-OH vitamin D levels on the severity of asthma. The severity of asthma was determined mainly by the duration of asthma diagnosis, a number of attacks in the previous year, anti-inflammatory medication usage in a previous year, atopy presence in the family, skin prick test positivity, and immunoglobulin E (IgE) levels of asthma patients. Results Compared with control groups, asthma patients had significantly lower 25-OH vitamin D, calcium (Ca) levels, and higher number of patients who had a 25-OH vitamin D deficiency, (p<0.0001, p<0.0001, p<0.0001, respectively). We found a correlation between blood 25-OH vitamin D levels and force expiratory capacity in one second (FEV1) and forced vital capacity (FVC) respectively (p< 0.001, r=0.512), (p< 0.001, r=0.513). There was an association between FEV1, FVC and blood 25-OH vitamin D levels in terms of deficient levels (<20 ng/mL) or insufficient levels (≥20 and <30 ng/mL) (p<0.001, r=0.459), (p< 0.001, r=0.450), respectively. Conclusions The 25-OH vitamin D levels were lower in pediatric asthma patients with worse spirometry results. Effects of Vitamin D supplementation need to be evaluated by well-designed studies.

Abstract
Monitoring and treating iron overload is crucial in transfusion-dependent thalassaemia patients. Liver stiffness measurement by transient elastography and T2* magnetic resonance imaging represent non-invasive ways to evaluate the adequacy of the iron chelation treatment. We explored the role of single nucleotide polymorphisms involved in vitamin D metabolism, transport and activity, and in deferasirox metabolism on liver iron burden parameters. One-hundred and five beta-thalassaemia patients, treated with deferasirox, have been enrolled. Drug plasma Ctrough and AUC were measured by a HPLC-UV method. Allelic discrimination was performed by real-time PCR. Age, UGT1A1-364 CT/TT and CYP27B1 -1260 GT/TT positively predicted liver stiffness values. Deferasirox dose and serum ferritin negatively predicted T2* data, whereas age and CYP2D6 1457 GG genotype positively influenced these values. The discoveries of this research may be useful for personalized medicine and the proposed method could be applied in patients with hereditary hemochromatosis and myelodysplastic syndromes.

Abstract
BACKGROUND Little is known about the genetic background of urinary tract infection (UTI) in children. METHODS In this study, vitamin D receptor (VDR) gene polymorphisms were compared between 60 children with UTI (case group) and 60 healthy children (control group). DNA extraction, polymerase chain reaction, and the restriction fragment length polymorphism methods were used to perform the genetic analysis. RESULTS There was a significant difference between the case and control groups for VDR gene, ApaI and Bsml, polymorphisms (P < 0.05). The frequency of VDR Bb, bb, Aa, and aa genotypes, and the b and a alleles in the case group was significantly higher than that in the control group (P < 0.05). A significant difference was also found between lower UTI and acute pyelonephritis groups for the VDR Apal and Bsml genotypes (P < 0.05). There was no significant difference between children with first UTI and those with more than one UTI for VDR gene polymorphisms (P > 0.05). CONCLUSION This study showed that there is a significant relationship between VDR gene, Apal and Bsml, polymorphisms and UTI in children. The results indicate that these polymorphisms may play a role in pathogenesis of UTI.

Abstract
BACKGROUND The metabolism of vitamin D is complex, its receptor (VDR) and proteins encoded by the genes CYP27B2 and CYP24A1 can influence vitamin D serum levels. The aim of this study was to investigate the relationship of the polymorphisms of VDR (ApaI and BsmI), CYP27B1 and CYP24A1 with serum vitamin D levels in both forms, 25(OH)D3 (circulating form) and 1,25(OH)2D3 (active form), in colorectal cancer (CRC) patients. METHODS One hundred fifty-two CRC patients and 321 controls were included. DNA was extracted from peripheral blood. Polymorphisms of BsmI and ApaI were identified by PCR-RFLP. Those of CYP24A1 (rs6013897, rs158552 and rs17217119) and CYP27B1 (rs10877012) were determined by gene sequencing. RESULTS The median serum levels of circulating vitamin D were not different between CRC patients and controls; however, the percentage of those with deficient vitamin D was higher in patients with cancer. The active form of the vitamin D was higher in CRC patients. VDR, CYP27B1 and CYP24A1 polymorphic genotypes had no influence on serum levels of circulating vitamin D. The correlation between circulating and active vitamin D forms was lower among patients with CRC, regardless of the presence or absence of any genetic polymorphism. The mean serum levels of active vitamin D were higher among patients with polymorphic genotype variants of Apa1 or Bsm1. CONCLUSIONS CRC patients had a higher frequence of insufficient vitamin D and a higher concentration of active vitamin D. These concentration were higher between patients with polymorphic genotypes variants of ApaI and BsmI, CYP24A1 and CYP27B1. Polymorphic genotypes cause a lower correlation between the forms of vitamin D.

Association of Sun Exposure, Skin Colour and Body Mass Index with Vitamin D Status in Individuals Who Are Morbidly Obese. Nutrients 2017; 9:nu9101094.

Abstract
Vitamin D deficiency is a common issue, particularly in obese populations, and is tested by assessing serum 25(OH)D concentrations. This study aimed to identify factors that contribute to the vitamin D status in fifty morbidly obese individuals recruited prior to bariatric surgery. Data collected included serum 25(OH)D concentrations, dietary and supplement intake of vitamin D, sun exposure measures, skin colour via spectrophotometry, and genotype analysis of several single nucleotide polymorphisms in the vitamin D metabolism pathway. Results showed a significant correlation between serum 25(OH)D concentrations and age, and serum 25(OH)D and ITAC score (natural skin colour). Natural skin colour accounted for 13.5% of variation in serum 25(OH)D, with every 10° increase in ITAC score (i.e., lighter skin) leading to a 9 nmol/L decrease in serum 25(OH)D. Multiple linear regression using age, ITAC score, and average UV index in the three months prior to testing, significantly predicted serum 25(OH)D concentrations (R² = 29.7%). Single nucleotide polymorphisms for all vitamin D genes tested, showed lower serum 25(OH)D for those with the rare genotype compared to the common genotype; this was most pronounced for fok1 and rs4588, where those with the rare genotype were insufficient (<50 nmol/L), and those with the common genotype were sufficient (≥50 nmol/L). Assessing vitamin D status in individuals with morbid obesity requires testing of 25(OH)D, but potential risk factors for this population include natural skin colour and age.

Abstract
INTRODUCTION Vitamin D receptor (VDR) and proteins encoded by the genes CYP27B2 and CYP24A1 involved in the production and inactivation of vitamin D can influence vitamin D and the susceptibility to colorectal cancer (CRC). The objective of this study was to investigate the relationship between the risk of CRC and polymorphisms in VDR, CYP27B1 and CYP24A1, lifestyle and dietary habits. METHODS The study included 152 patients with CRC and 321 controls. All participants answered a questionnaire on their dietary habits, alcohol consumption and smoking habits. DNA was extracted from peripheral blood. Polymorphisms of BsmI and ApaI were identified by performing PCR-RFLP. Identification of CYP24A1 (rs6013897, rs158552 and rs17217119) and CYP27B1 (rs10877012) polymorphisms was performed by gene sequencing. RESULTS Smoking, alcohol use, and low or no consumption of fruit, cereals and dairy products were associated with an increased risk of CRC. A heterozygous genotype Aa or an association genotype aa + Aa of the VDR ApaI polymorphism increased the risk of CRC. The VDR BsmI polymorphism was not significantly associated with the risk of CRC. Multivariate analysis showed that heterozygous and association genotype AT + AA of the rs6013897 polymorphism, genotype CT of the rs158552 polymorphism, association genotype CT + CC and genotypes AA and GG of the rs17217119 polymorphism of CYP24A1, and heterozygous genotype GT and association genotype GT + TT of the rs10877012 polymorphism in CYP27B1 were associated with a higher risk of CRC. CONCLUSIONS Dietary habits, lifestyle, and polymorphisms in VDR (ApaI), CYP24A1 (rs6013897, rs158552, rs17217119) and CYP27B1 (rs10877012) were associated with a higher risk of CRC.

Abstract
BACKGROUND The prevalence of vitamin D (vitD) deficiency presenting as rickets is increasing worldwide. Insufficient sun exposure, vitD administration, and/or calcium intake are the main causes. However, vitD system-related genes may also have a role. METHODS Prospective study: 109 rachitic children completed a 6-mo study period or until rachitic manifestations disappeared. Thirty children were selected as controls. Clinical and biochemical data were evaluated at baseline in patients and controls and biochemistry re-evaluated at radiological healing. Therapy was stratified in three different protocols. Fifty-four single-nucleotide polymorphisms (SNPs) of five vitD system genes (VDR, CP2R1, CYP27B1, CYP24A1, and GC) were genotyped and their association with clinical and biochemcial data was analyzed. RESULTS Therapy response was similar in terms of radiological healing although it was not so in terms of biochemical normalization. Only VDR gene (promoter, start-codon, and intronic genotypes) was rickets-associated in terms of serum 25-OH-D, calcium, radiological severity and time needed to heal. Eight patients with sufficient calcium intake and 25-OH-D levels carried a VDR genotype lacking minor allele homozygous genotypes at SNPs spread along the gene. CONCLUSION Although patients presented epidemiologic factors strongly contributing to rickets, genetic modulation affecting predisposition, severity, and clinical course is exerted, at least in part, by VDR gene polymorphic variation.

Association of VDBP and CYP2R1 gene polymorphisms with vitamin D status in women with polycystic ovarian syndrome: a north Indian study. Eur J Nutr 2016; 57:703-711.

Abstract
PURPOSE Polycystic ovarian syndrome (PCOS) is the most common endocrine abnormality among women of reproductive age and is usually associated with oligo-ovulation/anovulation, obesity, and insulin resistance. Hypovitaminosis D may also be a primary factor in the initiation and development of PCOS. However, little is known about the role of genetic variation in vitamin D metabolism in PCOS aetiology. Therefore, we studied the genetic polymorphisms of CYP2R1 and vitamin D binding protein (VDBP) in an Indian population. METHODS Serum vitamin D was measured by ELISA. Genotyping of VDBP single nucleotide polymorphisms (SNPs) rs7041 (HaeIII; G>T) and rs4588 (StyI; A>C) and CYP2R1 SNP rs2060793 (HinfI; A>G) was carried out by restriction fragment length polymorphism in 50 cases of PCOS that were compared with 50 age-matched healthy women. RESULTS Vitamin D levels were found to be significantly lower in women with PCOS (p = 0.008) than in age-matched controls. There was no significant difference in genotype frequencies of all three polymorphisms (rs7041, rs4588, and rs2060793) between PCOS and control women. In women with a vitamin D deficiency (<20 ng/ml), the GT allele of the VDBP SNP rs7041 (p value =0.04), the VDBP allelic combination Gc1F/1F (T allele of rs4588 and C allele of rs7041) (p value =0.03), and the GA allele of the CYP2R1 SNP rs2060793 (p = 0.05) were associated with an increased risk of developing PCOS. CONCLUSIONS The present study shows that the GT allele of VDBP SNP rs7041, the VDBP allelic combination (GC1F/1F), and GA allele of CYP2R1 SNP rs2060793 in vitamin D deficient women increase the risk of PCOS.

Abstract
AIM To survey dietitians on their knowledge and practices regarding vitamin D (VitD) intake, sources, supplementation and effect on disease state. METHODS An online survey was disseminated to members of the Dietitian Association Australia via the weekly online state newsletter during April 2015. Response rate was 3%, with 134 respondents completing the survey. The survey included questions about knowledge and current practices. Descriptive statistics were used to analyse the results. RESULTS Dietitians have good knowledge regarding dietary sources of VitD and roles in the body, but there is confusion around supplement doses for treatment and prevention of deficiency and sun exposure guidelines. CONCLUSIONS Dietitians are well positioned to provide patients with advice on VitD supplementation and sun exposure practices, but not all are confident to provide this care. There is a need for clear and well-disseminated guidelines for VitD management by dietitians.

Abstract
Bioactive vitamin D is a steroid hormone transported in blood via the vitamin D binding protein (DBP). Our study aimed to investigate the vitamin D status in a young Lebanese population and study the association of hypovitaminosis with levels of DBP. Polymorphisms in the GC gene that encodes DBP were also screened. Blood samples were collected from 179 university students. Vitamin D status and DBP levels were assayed by enzyme-linked immunosorbent assay (ELISA). DNA was extracted from 128 participants, and genotyping of the two GC gene SNPs, rs7041, and rs4588, was carried out by restriction fragment length polymorphism. Forty-seven percent of participants had hypovitaminosis D (<20 ng/ml). A significant positive correlation was observed between vitamin D status and DBP. Genotyping data showed that participants carrying the rs7041 GG and rs4588 AA genotypes had higher concentrations of DBP than those carrying other genotypes. Four allelic versions of the GC gene were observed, one of which, GC*3, was encountered for the first time in this study, and was found to be associated with both normal vitamin D and high DBP levels. Modifying genes such as GC could therefore affect DBP levels, and contribute, along with environmental factors, to the hypovitaminosis D observed in sunny countries.

Detection of Hereditary 1,25-Hydroxyvitamin D-Resistant Rickets Caused by Uniparental Disomy of Chromosome 12 Using Genome-Wide Single Nucleotide Polymorphism Array. PLoS One 2015; 10:e0131157.

Abstract
Context Hereditary 1,25-dihydroxyvitamin D-resistant rickets (HVDRR) is an autosomal recessive disease caused by biallelic mutations in the vitamin D receptor (VDR) gene. No patients have been reported with uniparental disomy (UPD). Objective Using genome-wide single nucleotide polymorphism (SNP) array to confirm whether HVDRR was caused by UPD of chromosome 12. Materials and Methods A 2-year-old girl with alopecia and short stature and without any family history of consanguinity was diagnosed with HVDRR by typical laboratory data findings and clinical features of rickets. Sequence analysis of VDR was performed, and the origin of the homozygous mutation was investigated by target SNP sequencing, short tandem repeat analysis, and genome-wide SNP array. Results The patient had a homozygous p.Arg73Ter nonsense mutation. Her mother was heterozygous for the mutation, but her father was negative. We excluded gross deletion of the father’s allele or paternal discordance. Genome-wide SNP array of the family (the patient and her parents) showed complete maternal isodisomy of chromosome 12. She was successfully treated with high-dose oral calcium. Conclusions This is the first report of HVDRR caused by UPD, and the third case of complete UPD of chromosome 12, in the published literature. Genome-wide SNP array was useful for detecting isodisomy and the parental origin of the allele. Comprehensive examination of the homozygous state is essential for accurate genetic counseling of recurrence risk and appropriate monitoring for other chromosome 12 related disorders. Furthermore, oral calcium therapy was effective as an initial treatment for rickets in this instance.

Abstract
Epilepsy is one of the most common neurologic disorders in childhood that often requires long term treatment with antiepileptic drugs. Both antiepileptic treatment and the comorbidities associated with epilepsy have a negative impact on bone health in growing children. Given the fact that vitamin D deficiency is a major public health problem worldwide, clinicians caring for children with chronic diseases should be aware of effects of the medication on the bone metabolism. Yet, vitamin D deficiency due to antiepileptic treatment is an overlooked issue among neurologists. In this review, we briefly describe vitamin D metabolism and the effect of vitamin D in the brain. We also discuss the literature in terms of vitamin D deficiency and antiepileptic treatment in the pediatric population.

Abstract
Background and Aims Vitamin D exerts immunomodulatory effects on the host response against infection with hepatitis C virus (HCV). This study was performed to assess the putative influence of polymorphisms in vitamin D-related genes on the response to antiviral therapy in patients with chronic hepatitis C (CHC). Methods Single nucleotide polymorphisms (SNPs) in CYP27B-1260 gene promoter (rs10877012AC) and in vitamin D receptor (VDR) gene rs2228570TC, rs1544410CT, rs7975232AC and rs731236AT were analyzed in a cohort of 238 Caucasian CHC patients treated with pegylated interferon (Peg-IFN) plus ribavirin (RBV). Multivariate analyses were performed to exclude confounding effects of well-known baseline predictors of response to therapy (HCV genotype and load, IL28B genotype, age, and GGT and serum cholesterol). Results Three SNPs at the VDR gene (rs1544410, rs7975232 and rs731236) were in strong linkage disequilibrium, with the CCA haplotype predicting therapeutic failure [Odds ratio 2.743; (95% C.I. 1.313–5.731), p = 0.007]. The carrier state of the VDR rs2228570 T allele was inversely related to the probability of therapeutic failure [Odds ratio 0.438; 95 C.I. (0.204–0.882), p = 0.021]. No relation existed between CYP27B-1260 rs10877012 polymorphism and response to therapy. The area under the operating curve (AUROC) based on the model including all variables significantly related to the response to therapy was 0.846 (95% confidence interval = 0.793–0.899). Conclusion VDR gene polymorphisms are independently related to the response to Peg-IFN+RBV therapy in chronic hepatitis C and could be used as complementary biomarkers of response when included in a prediction algorithm in association with demographic, virologic, biochemical and genetic traits.
