Association between vitamin D receptor gene variants and neonatal sepsis: A systematic review and meta-analysis. J Infect Public Health 2024; 17:518-526. [PMID: 38306913 DOI: 10.1016/j.jiph.2024.01.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 12/27/2023] [Accepted: 01/14/2024] [Indexed: 02/04/2024] Open
Abstract
The objective of this systematic review and meta-analysis was elucidating the association of VDR SNPs (FokI, TaqI, BsmI, BgII, and ApaI) with neonatal sepsis. Literature search was performed to retrieve records published until August 2nd, 2023 (PROSPERO registration: CRD42023451355). Meta-analysis was carried out to determine the pooled estimates for Odds Ratio (OR). A total of four studies were included with 500 neonates (250 sepsis cases and 250 healthy controls). There was an association observed between TaqI SNP with neonatal sepsis for CT vs. CC+TT (OR=1.95) and TT vs CT+CC (OR=0.40). Moreover, the pooled estimates also suggested that CC vs. CT+TT (OR= 0.37) and C vs. T (OR=0.66) of FokI SNP were significantly associated with neonatal sepsis. SNP of BgII was found to be significantly associated with neonatal sepsis, but only reported in a single study.

Abstract
BACKGROUND Sepsis is life-threatening organ dysfunction as a result of the host's dysregulated immune response to infection. The vitamin D receptor (VDR) gene FokI polymorphism influences immune cell behavior. In the present study, we aimed to investigate the association between VDR FokI polymorphism and mortality in sepsis and non-sepsis patients in the intensive care unit (ICU). METHODS AND RESULTS This is a prospective observational study involving 96 sepsis and 96 non-sepsis patients admitted to the Ege University ICU. VDR FokI polymorphisms were investigated, as well as the relationship between the identified polymorphisms and mortality. In-hospital mortality was 27.1% in the sepsis group and 8.33% in the non-sepsis group (p = 0.001). The frequencies of VDR FokI TT, TC, and CC genotypes were 8 (8.33%), 48 (50.0%), and 40 (41.7%) in the sepsis group, and 11 (11.5%), 42 (43.8%), and 43 (44.8%) in the non-sepsis group, respectively (p = 0.612). In the sepsis group, the frequencies of Fokl TT, TC, and CC genotypes did not differ significantly between survivors and non-survivors. However, homozygous C allele carriers had lower overall mortality (p = 0.047). CONCLUSION The VDR FokI polymorphism, particularly the CC genotype, appears to be associated with lower mortality in ICU patients.

Abstract
BACKGROUND To investigate the association between sepsis and the vitamin D receptor (VDR) gene polymorphisms. METHODS Databases including PubMed, Cochrane Library, EMbase, CNKI, Wanfang Data, and VIP Data were systematically searched. The association was assessed using odds ratios (ORs), and 95% confidence intervals (CIs). The statistical tests were performed using Review Manager 5.4. RESULTS We identified a total of 5 studies. The relationship between VDR gene polymorphisms (Apa I, Bsm I, Taq I, and Fok I), and incidence of sepsis was investigated. The results of this meta-analysis showed that the allelic contrast model (F vs f, P = .03, OR = 0.65, 95% CI = 0.44-0.95), dominant genetic model (FF vs Ff + ff, P = .02, OR = 0.53, 95% CI = 0.30-0.91), and codominance genetic model (FF vs ff, P = .03, OR = 0.39, 95% CI = 0.16-0.91) of VDR Fok I locus increased the risk of sepsis, and the lack of association between the VDR Fok I gene polymorphism and the risk assessment of sepsis, based on the ethnic subgroup analysis, might be attributable to the small sample size. The risk of sepsis with Apa I, Bsm I, and Taq I did not appear to be correlated. CONCLUSION SUBSECTIONS This meta-analysis revealed that the VDR Fok I polymorphism is closely associated with the susceptibility to sepsis, and patients with sepsis have lower 25-hydroxyvitamin D levels. VDR Fok I gene mutations may change the risk of sepsis.

Abstract
BACKGROUND Previous studies have documented vitamin D imbalance in dogs with acute pancreatitis (AP), but no studies have investigated serum vitamin D receptor (VDR) and vitamin D-binding protein (VDBP) concentrations. OBJECTIVES Compare serum 25-hydroxyvitamin D (25[OH]D), VDR, and VDBP concentrations in healthy dogs and dogs with AP and identify correlations between these concentrations with ionized calcium, C-reactive protein (CRP), and canine-specific pancreatic lipase (Spec cPL) concentrations. ANIMALS Twenty-two dogs with AP and 20 healthy control dogs. METHODS Prospective cross-sectional study. Serum 25(OH)D concentrations were measured using a chemiluminescence immunoassay, and VDR and VDBP concentrations were measured using a ELISA kit designed for dogs. RESULTS Serum concentrations of 25(OH)D were lower in dogs with AP (mean ± SD, 66.1 ± 39.2 ng/mL) than in controls (96.8 ± 30.4 ng/mL; P = .01), and VDR concentrations were lower in dogs with AP (5.3 ± 3.5 ng/mL) than in controls (7.4 ± 2.5 ng/mL; P = .03). No difference was observed in serum VDBP concentrations between the groups. Serum VDR concentrations differed between survivors (median [interquartile range] = 6.6 [4.3-8.2] ng/mL) and nonsurvivors (2.7 [0.5-3.5] ng/mL; P = .01). Negative correlations were observed among serum VDR, CRP (rs = -0.55), and Spec cPL (rs = -0.47) concentrations in dogs with AP. CONCLUSIONS AND CLINICAL IMPORTANCE Dogs with AP had lower serum 25(OH)D and VDR concentrations than controls. Additionally, our study suggests a potential role of VDR expression in the inflammatory process of AP in dogs.

Abstract
Abstract
Background
Vitamin D is a fat-soluble vitamin that regulates calcium and phosphorous homeostasis to maintain a healthy mineralized skeleton. It can also influence immune responses and has immunomodulatory properties. Vitamin D receptor (VDR) is a nuclear receptor that mediates the activities of the hormonal form of vitamin D. VDR polymorphisms can alter immunity and susceptibility to infections by modulating VDR expression and vitamin D activity. This study aimed to investigate the levels of serum vitamin D as well as four VDR polymorphisms: FokI, BsmI, ApaI, and TaqI in fifty children admitted to intensive care unit (ICU) with a diagnosis of sepsis and one-hundred age- and sex-matched healthy children.
Methods
Vitamin D levels were measured in serum, in both patients and controls, using an enzyme-linked immunosorbent assay (ELISA) approach. VDR polymorphisms were also studied in both groups using specific restriction enzymes.
Results
Vitamin D levels were low in both patients and controls. Moreover, serum levels were unaffected by VDR polymorphisms, and their distribution was similar in both groups. Neither the need for mechanical ventilation or inotropic treatment nor the sepsis outcome was impacted by serum vitamin D levels or VDR polymorphisms.
Conclusion
In children admitted to pediatric ICU, neither vitamin D levels nor VDR polymorphisms were associated with sepsis. Further larger studies including different types of sepsis are recommended.

Abstract
Background: Vitamin D deficiency has been associated with increased sepsis incidence and mortality in various populations. Vitamin D exerts its effect through vitamin receptor (VDR), and various single nucleotide polymorphisms have been reported to affects the expression and structure of the VDR. In the present study, we investigated the possible role of vitamin D deficiency and VDR polymorphisms in susceptibility to sepsis.Methods: 576 sepsis patients and 421 healthy controls were enrolled in the present study. Plasma vitamin D levels in patients and healthy controls were quantified by ELISA. Genetic variants in the VDR (FokI, TaqI, BsmI, and ApaI) were genotyped by TaqMan assay.Results: Reduced serum Vitamin D level was observed in subjects with sepsis compared to healthy controls (p ≤ 0.0001). Further, subjects with septic shock had diminished 25(OH) vitamin D compared to severe sepsis cases (p ≤ 0.0001). FokI variants and minor alleles were more prevalent in sepsis patients compared to healthy controls (Ff: p ≤ 0.0001, χ2 =17.39; ff: p=0.001, χ2 =10.79; f: p ≤ 0.0001, χ2 =23.51). Furthermore, combined plasma levels of 25(OH) vitamin D and FokI polymorphism revealed a significant role in a predisposition to sepsis and septic shock. However, the prevalence of other VDR polymorphisms (TaqI, BsmI and ApaI) were comparable among different clinical categories.Conclusions: Low 25(OH) vitamin D levels and FokI mutants are associated with an increased risk of sepsis and septic shock in a Chinese cohort.Clinical significanceLower levels of 25-OH vitamin D are highly prevalent in Sepsis patients.Subjects harbouring VDR FokI variants are predisposed to susceptibility to sepsis in the studied cohort.

Abstract
Background We designed an association study among 267 cases of children with sepsis and 283 healthy controls, by genotyping 9 variants in the VDR gene. Material/Methods This was a hospital-based, case-control, genetic association study. In addition to 3 genetic modes of inheritance, haplotype and interaction analyses were employed to examine the prediction of VDR gene for pediatric sepsis. Effect-size estimates are expressed as odds ratio (OR) and 95% confidence interval (CI). Results Two variants in the VDR gene, rs2107301 and rs2189480, were found to play a leading role in susceptibility to sepsis in children. The mutant homozygotes of rs2107301 (CC) and rs2189480 (CC) were associated with a reduced risk of sepsis compared with the corresponding wild homozygotes (OR: 0.44 and 0.43, 95% CI: 0.21–0.92 and 0.23–0.81, p: 0.03 and 0.009, respectively). The mutations of rs2107301-C and rs2189480-C alleles were associated with reduced sepsis risk. Haplotype C-C-C-C-C-T-C-A-G in the VDR gene was significantly associated with a 0.59-fold decreased risk of sepsis (95% CI: 0.12–0.76, p: 0.02). In the haplotype–phenotype analysis, significant association was noted for high-density lipoprotein, even after simulation correction (psim <0.05). Conclusions Taken together, our findings indicate that the VDR gene may be a sepsis-susceptibility gene in Chinese Han children.

Abstract
Abstract
Objective The vitamin D receptor gene (VDR) polymorphisms and the risk of various infections have been studied. An association with brucellosis and vitamin D levels has been investigated but not yet with VDR gene polymorphisms. We aimed to examine the association between VDR gene polymorphisms and susceptibility to childhood brucellosis.
Methods This case–control study included patients with brucellosis and healthy controls. After extracting genomic DNA using a Qiagen blood DNA isolation kit, five VDR single nucleotide polymorphisms (SNPs), including Cdx-2, FokI, BsmI, ApaI, and TaqI gene, were amplified. Genetic distribution of these SNPs of VDR gene in patient and control groups were compared.
Results A total of 38 patients with brucellosis and 89 healthy controls were evaluated. The genotype distribution of Cdx2, FokI, BsmI, and ApaI polymorphisms were similar between patients and healthy controls. However, the CC homozygous genotype for VDR gene TaqI was significantly overexpressed in patients compared with controls (23.7 vs. 7.9%; p = 0.042). The frequency of the C allele of the TaqI genotype was significantly different between patients and controls (p = 0.018). On the other hand, presence of the A allele in the BsmI was associated considerably with an increased risk of brucellosis (p = 0.037). VDR polymorphism distribution was similar according to age, presence of complicated disease, and presence of bacteremia. The heterozygote TaqI polymorphism was more common in patients presented as subacute and chronic symptoms (p = 0.036).
Conclusion Our results indicated the possible role in TaqI polymorphism of the VDR gene for the risk of brucellosis at the time of exposure to infection.

Abstract
INTRODUCTION Vitamin D deficiency in children is related to the augmented risk of bone illnesses, but its effect on critically ill children is still conflicting. This meta-analysis study was performed to assess the relationship between vitamin D deficiency in children and sepsis, paediatric risk of mortality III score, need for ventilation support, length of hospital stay, and duration of mechanical ventilation in critically ill children. METHODS Through a systematic literature search up to June 2020, 16 studies with 2382 children, 1229 children of them with vitamin D deficiency, were found recording relationships between vitamin D deficiency and sepsis, paediatric risk of mortality III score, need for ventilation support, length of hospital stay, and/or duration of mechanical ventilation. Odds ratio (OR) with 95% confidence intervals (CIs) was calculated between vitamin D deficiency children to non-vitamin D deficiency children on the different outcomes in critically ill children using the dichotomous or continuous methods with a random or fixed-effect model. RESULTS The vitamin D deficiency children category had significantly higher sepsis (OR, 2.35; 95% CI, 1.19-4.63, P = .01); paediatric risk of mortality III score (OR, 2.19; 95% CI, 1.13-4.25, P = .02); higher length of hospital stay (OR, 4.26; 95% CI, 0.81-7.70, P = .02); higher duration of mechanical ventilation (OR, 1.89; 95% CI, 0.22-3.56, P = .03) compared with that in the non-vitamin D deficiency children. However, the need for ventilation support in vitamin D deficiency children did not significantly differ from non-vitamin D deficiency children (OR, 2.00; 95% CI, 0.98-4.07, P = .06) with relatively higher results in vitamin D deficiency children. CONCLUSIONS Vitamin D deficiency in children might have an independent relationship with higher sepsis, paediatric risk of mortality III score, length of hospital stay, and duration of mechanical ventilation. The relation was relative with a higher risk in need for ventilation support with vitamin D deficiency children. This relationship encouraged us to recommend testing vitamin D levels in all critically ill children and providing them with supplemental vitamin D as prophylaxis.

Abstract
Sepsis is a life-threatening disorder and leads to organ dysfunction and death. Therefore, searching for more alternative biomarkers is of great significance for sepsis assessment and surveillance. In our study, the gene expression profiles of 163 samples from healthy controls and septic patients were analyzed and 8 gene co-expression modules were identified by constructing weighted gene co-expression network. The blue and yellow modules showed close correlations with the phenotypic trait "days postsepsis." Besides, differentially expressed genes (DEGs) over time in septic patients were screened using Short Time-series Expression Miner (STEM) program. The intersection of genes in the blue and yellow modules and DEGs, which were significantly enriched in "HTLV-1 infection" pathway, was analyzed with protein-protein interaction network. The logistic regression model based on these eight mRNAs was constructed to determine the type of the sample reliably. Eight vital genes CECR1, ANXA2, ELANE, CTSG, AZU1, PRTN3, LYZ, and DEFA4 presented high scores and may be associated with sepsis, which provided candidate biomarkers for sepsis.

Abstract
BACKGROUND The consequences of vitamin D deficiency regarding sepsis in children remain controversial. We conducted a meta-analysis of studies evaluating the association between vitamin D status and sepsis in children. METHODS We used EMBASE, Ovid Medline and Cochrane Library to conduct a meta-analysis of studies published in English before November 21, 2017. RESULTS Among 1146 initially identified studies, we included 13 studies according to predefined inclusion criteria comprising 975 patients and 770 control participants. According to a random effects model, the mean difference in 25(OH)D levels (nmol/L) between participants with sepsis (444) and controls (528) was (mean difference, -18.55; 95% confidence interval (CI), -19.45 to -17.66, p < 0.05). The association between vitamin D deficiency and sepsis was significant, with an odds ratio (OR) = 1.13 (95% CI, 1.18 to 1.50, p < 0.05). Factors that could explain differences in the results include the study location/medical conditions, study design, 25(OH)D assay methods, diagnostic sepsis at different ages, diagnostic criteria for sepsis, and sepsis with comorbidities. CONCLUSIONS The association between vitamin D deficiency/lower 25(OH)D levels and sepsis was significant in children and neonates. Further studies are required to confirm the results by considering more confounders.

Association of vitamin D receptor ApaI gene polymorphism with osteoporosis susceptibility in postmenopausal Han Chinese women in Xinjiang. Biomed Rep 2018; 9:483-490. [PMID: 30546875 PMCID: PMC6256115 DOI: 10.3892/br.2018.1155] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2017] [Accepted: 09/20/2018] [Indexed: 02/06/2023] Open
Abstract
Osteoporosis is a polygenic disorder and has been demonstrated to be associated with ~30 candidate genes, the majority of which have also been implicated in the regulation of bone mineral density (BMD). Vitamin D receptor (VDR) is the candidate gene that has been most extensively studied. Certain studies have reported that the VDR single nucleotide polymorphism ApaI is associated with the risk of osteoporosis in Caucasian and African women. However, this association has not yet been studied in postmenopausal Han Chinese women in the Xinjiang area. In the present study, ApaI polymorphisms of VDR were defined by polymerase chain reaction-restriction fragment length polymorphism, in order to analyze the distribution of ApaI polymorphisms in postmenopausal Han Chinese women from Xinjiang. BMD was measured by dual energy X-ray absorptiometry at the lumbar spine (L2-4), Ward's triangle, great trochanter and femoral shaft. A total of 336 women were included in this study. The genotype distribution of ApaI was consistent with the Hardy-Weinberg equilibrium (all P>0.05). There were no significant differences in ApaI genotype frequencies between the 90 cases in the osteoporosis group and 246 cases in the non-osteoporosis group (P=0.946). Meanwhile, it was identified that BMD values of the tested locations were negatively correlated with age (P<0.05) and positively correlated with body mass index (BMI; P<0.05). On further attribution risk analysis, BMD was identified as a risk factor [odds ratio (OR): 0.464, 95% confidence interval (CI): 0.372-0.580, P=0.001] and BMI a protective factor (OR: 1.502, 95% CI: 1.008-2.240, P=0.032) in osteoporosis. When BMD was adjusted for confounding factors including age and BMI, it was observed that the ApaI polymorphism was not associated with BMD at the sites tested (P>0.05). In conclusion, the present study identified no significant association of the common VDR polymorphism ApaI with BMD at several skeletal sites in postmenopausal Han Chinese women in the Xinjiang area. Age was negatively correlated with BMD at different sites and identified as a risk factor; while BMI was positively correlated with BMD and identified as a protective factor.

Abstract
BACKGROUND AND AIM Increasing prevalence of neonatal sepsis in recent years catch attention to early prevention and management. Vitamin D receptor (VDR) polymorphism can modulate VDR expression level that greatly influences immunity and susceptibility to microbial infections. We aimed to investigate the association of VDR polymorphism at FokI, rs2228570 T/C, and TaqI, rs731236 C/T gene with serum 25-hydroxyvitamin D level and risk of neonatal sepsis. METHODS This work carried on 160 subjects classified into 80 cases (40 mothers and their 40 septic neonates) and 80 healthy controls (40 volunteer mothers and their 40 healthy neonates). Genotyping of VDR polymorphisms were assayed by real-time PCR and serum 25-hydroxyvitamin D level and hs-CRP were measured by ELISA. RESULTS Vitamin D deficiency was observed in mothers of cases compared with healthy ones (p = <0.001) and in septic neonates versus healthy ones (p = <0.001). Septic neonates had much higher VDR FokI TT genotype (p = 0.014) and T allele (p = 0.003) versus healthy ones. TT genotype and T allele could increase the risk of sepsis with OR 95% CI [4.804 (1.4-16.4)] and [2.786 (1.4-5.7)] respectively while VDR TaqI showed no association with sepsis. There was a strong LD between FokI and TaqI in sepsis cases. In sepsis, T/T genotype at FokI had significantly lower vitamin D (p = <0.001). CONCLUSION Vitamin D deficiency in mothers/neonates is a risk factor for neonatal sepsis. VDR FokI T allele had lower 25-hydroxyvitamin D level that may predispose to sepsis hazards.
