Association of Vitamin D with the TaqI Polymorphism of the VDR Gene in Older Women Attending the Basic Health Unit of the Federal District, DF (Brazil)

Aging is accompanied by various functional modifications determined by their environment, lifestyle, nutrition, and genetics. Based on these factors, it is essential to verify the vitamin deficiency in the elderly population. Hypovitaminosis D is commonly present in human aging, increasing the chances of developing noncommunicable chronic diseases. The VDR gene TaqI polymorphism may modify the vitamin D metabolic pathway by altering the interaction between the vitamin D receptor and the active circulating vitamin D. Therefore, this study aimed to investigate the association between serum vitamin D and biochemical and genetic factors, considering the TaqI polymorphism of the VDR gene, in an elderly population of the Federal District. The study was a descriptive, case-control, quantitative, and cross-sectional type and was conducted in two basic health units in the administrative region of Ceilândia, Federal District, DF, Brazil, with women aged 60 years or older. Anthropometric, biochemical, and genetic parameters (VDR TaqI polymorphism) were evaluated. The adopted significance level was 5%, and statistical analyses were performed using the SPSS version 20.0 program. The study consisted of 128 participants. The most prevalent age was from 60 to 65 years (N = 53; 41.4%). 66 elderly (51.6%) were part of the case group (hypovitaminosis D), while 62 were in the control group. In the case group, 30.2% had grade I obesity, 77.3% were hypertensive, and 51.5% were diabetic. The TT genotype was present in 47% of the case group and 54.8% in the control group (p=0.667). There was no association between serum vitamin D levels and the VDR gene variant TaqI polymorphism in an elderly Brazilian population.

Background Vitamin D deficiency and vitamin D receptor (VDR) gene polymorphisms are strongly associated with tuberculosis (TB) susceptibility in countries with four seasons. As a country with sufficient sunlight for vitamin D production in skin, the incidence of TB in Indonesia remains high. Objective To assess for possible associations between the incidence of tuberculosis and serum vitamin D level, as well as VDR FokI polymorphisms in children. Methods A case-control study was conducted at the Department of Child Health, Dr. Mohammad Hoesin Hospital, Palembang from November 2011 to April 2012. Subjects were children with TB (the case) and children without TB who had been exposed to TB in the home (the control). Serum vitamin D [1,25(OH)2D3 or calcitriol] level was measured by immunodiagnostic system (IDS) 1,25-dihydroxy vitamin D enzyme immunoassay (EIA) kit. The VDR FokI polymorphisms were identified by polymerase chain reaction (PCR) and restriction-fragment length polymorphism (RFLP) analysis. Results Sixty subjects was divided equally into the case and control groups. The mean serum calcitriol level in the case group was significantly lower than that of the control group [105.5 (SD 66.9) pmol/L vs. 162.9 (SD 52.9) pmol/L, respectively; (P=0.001)]. We found 9 subjects with calcitriol deficiency, 8 in the TB group and 1 in the healthy contact group (OR 10.5; 95%CI 1.2 to 90.7) The VDR FokI polymorphism was seen in 28 subjects in the case group and 22 in the control group (OR 5.0; 95%CI 0.9 to 26.4). Conclusion Vitamin D (calcitriol) deficiency and lower serum levels are associated with higher risk of TB in children. The VDR gene FokI polymorphism also contributes to susceptibility for TB.

The Mean

Despite the abundant sunlight, vitamin D deficiency is prevalent in South Asian countries including Bangladesh. Information on vitamin D level is insufficient in adults particularly in female garment workers in Bangladesh. This study was designed to evaluate the status of vitamin D, parathormone (PTH), calcium, and alkaline phosphatase (ALP) among the female garment workers in Bangladesh. Blood samples were collected from female garment workers (n=40, case group) and general female workers (n=40, control group) in Dhaka. Serum vitamin D, PTH, calcium, and ALP were measured by chemiluminescence microparticle immunoassay. The mean level of vitamin D was significantly (p<0.001) lower in case (14.2±2.6 ng/mL) than in the control (22.4±2.4 ng/mL) group. No significant difference was found at mean of PTH and calcium between case (33.9±17.2 pg/mL;9.1±0.6 mg/dL, resp.) and control (35.9±16.3 pg/mL;9.3±0.6 mg/dL, resp.) group. The mean ALP in case (117.2±14.4 U/L) group was significantly (p<0.001) higher than the control group (80.5±30.6 U/L). Overall, PTH level did not show significant correlation with vitamin D. However, calcium and ALP levels showed a significant positive (p<0.05) and negative (p<0.001) correlation with vitamin D, respectively. This study indicates a high prevalence of vitamin D deficiency in the female garment workers in Bangladesh.

Background: This study was done to evaluate the association of serum vitamin D level with GDM (n=30) and without GDM (n=30). The age and body mass index of the participants along with their gestational age, gravidity and parity were harmonized. The serum vitamin D levels and blood glucose were investigated. The results revealed that, normal pregnant women had significantly higher vitamin D level than their GDM counterparts.Methods: This case-control study was conducted on healthy pregnant women attending routine antenatal care at Bangabandhu Sheikh Mujib medical university from January 2019 to December 2019 recruited at third trimester of gestation. We measured maternal serum vitamin D status (25[OH]D) in third trimester of pregnancy. GDM was diagnosed according to the American diabetes association. guidelines. Vitamin D status was defined as, vitamin D sufficiency (≥30 or ≥75 nmol/L), insufficiency (20-30 and 50-75 nmol/L), were used to categories participants according to their 25[OH]D concentrations. We calculated adjusted odds ratios and 95% confidence intervals (CIs) using logistic regression.Results: The mean serum vitamin D level was lower in case group case 23.4 (17.4±35.1) compared to that in control group 29.7 (15.4±39.8) and the difference between the 2 groups was statistically significant (p≤0.001). Sufficient level of vitamin D was more in control group (66.7%) than that of case group (26.1%). Insufficient level of vitamin D was higher in case (73.3%) group than that of control (33.3%) group. These findings were significant (p=0.021). Respondents with insufficient level of vitamin D have 3.1 times more chance to develop GDM.Conclusions: Serum vitamin D level is reduced in pregnant women having GDM.

Candida-associated denture stomatitis (CADS) is a fungal infection affecting 60–65% of denture wearers. Its etiology is complex and multifactorial and often associated with host immunodeficiency. Evidence exists that vitamin D has potential immunomodulatory and anti-inflammatory effects. The aim of this case–control study was to assess the association between vitamin D levels and CADS. The study included 32 complete denture wearers with CADS and 32 sex- and age-matched complete denture wearers without CADS. The patients were clinically examined, and the severity of denture stomatitis was assessed according to Newton’s classification scale. The serum vitamin D level was determined via the use of an electrochemiluminescence assay. The vitamin D level in the CADS group and control group was 54.68 ± 17.07 and 56.82 ± 17.75 nmol/L, respectively. There was no significant difference between the groups (p = 0.622). Univariate logistic regression analysis showed that the presence of CADS was not associated with hypovitaminosis D (odds ratio (OR) = 1.44; 95% confidence interval (CI) = 0.37–5.54). It can be concluded that vitamin D is not associated with CADS and does not play a significant role in host susceptibility to CADS. This finding suggests that vitamin D screening is not indicated routinely in patients with Candida-associated denture stomatitis.

Spontaneous Pregnancy

Background: Pregnancy loss in the first trimester is one of the most disappointing matters for a mother. But spontaneous pregnancy loss in the first trimester is the most common negative outcome of pregnancy. It's estimated that about 10% of known pregnancies are lost in the first trimester whereas fewer than 4% of pregnancies miscarry in the second trimester. Aim of current study was to assess the effect of the maternal vitamin D level on the risk of spontaneous pregnancy loss in the first trimester.Methods: It was a case-control study conducted in the department of obstetrics and gynecology, Sir Salimullah medical college Mitford hospital, Dhaka, Bangladesh during the period of September 2018 to August 2019. A total of 100 patients were included in this study. Statistical analyses of the results were obtained by using window-based computer software devised with SPSS version 22.0.Results: In analyzing the association of serum vitamin D status with first-trimester pregnancy state it was observed that more than half (52.0%) patients had severe deficiency (<10 ng/ml) in the case group and 14 (28.0%) patients in the control group. In total 24 (48.0%) patients had deficiency (10-20 ng/ml) in case and 35 (70.0%) in control group. Only 1 (2.0%) patient had insufficiency (21-29 ng/ml) in control group. The difference was statistically significant (p<0.05) between the two groups.Conclusions: Maternal serum vitamin D deficiency was significantly associated with early spontaneous pregnancy loss in the first trimester.

Abstract Objective Chronic spontaneous urticaria (CSU) is defined as urticaria with an unknown etiology which persists for more than 6 weeks. CSU is an uncomfortable cutaneous condition that occurs due to an immune-mediated inflammatory reaction. Many studies have demonstrated that vitamin D deficiency and single-nucleotide polymorphisms in the vitamin D receptor (VDR) impact the immune response. In the current study, the frequency of the Taq1 polymorphism in the VDR gene were compared between patients with CSU and individuals without CSU. Methods In a case–control study, a group of CSU patients (n = 100) was compared with a group of healthy age- and gender-matched individuals as a control group (n =100) who visited our center between 2015 and 2017. After DNA extraction from EDTA-containing blood, polymerase chain reaction (PCR–RFLP) was used to determine the presence of the Taq1 polymorphism. Serum vitamin D levels were measured using ELISA method (Abcam, Cambridge, USA). Results Genotyping for Taq1 polymorphism showed that TT, Tt and tt genes frequency in the CSU group were 36%, 54%, and 10% respectively. The TT, Tt and tt genotypes had a distribution of 50%, 47% and 3% respectively in the control group. The mean serum vitamin D level in the CSU group was 19.88 ± 8.14 ng/ml, which was not significantly correlated with the Taq1 polymorphism (P = 0.841). There was a significant relationship between Taq1 gene polymorphism (tt genotype) and CSU (P = 0.038). Tt genotype increased the risk of CSU (odds ratio = 1.596), and inheritance of tt genotype increased the risk even further (odds ratio = 4.630). Conclusion The frequency of Taq1 genotype polymorphism in the VDR gene was significantly higher in patients with CSU compared to the control group. The tt genotype polymorphism may be a risk factor for CSU.
