AbstractBackgroundVitamin D affects glucose metabolism by increasing insulin secretion and insulin receptor expression. Also, it exerts these effects by binding to its primary receptor, the vitamin D receptor (VDR). In this preliminary study, we aimed to examine serum 25-(OH) vitamin D3and serum VDR levels in gestational diabetes mellitus (GDM) patients.MethodsBlood samples were obtained during 24–28 weeks of pregnancy from patients with GDM (n=30) and age, body mass index (BMI), and gestational age-matched control subjects (n=33). Both groups were examined for changes in the levels of glucose, insulin, glycated hemoglobin (bA1c), 25-(OH) vitamin D3and VDR.ResultsThere were no significant differences in serum 25-(OH) vitamin D3and fasting insulin levels between the control and GDM groups (p=0.115, p=0.182). But serum VDR levels were significantly higher in the GDM group than in the control group (p=0.001).ConclusionsAlthough there was no significant difference between the two groups regarding 25-(OH) vitamin D3levels, it is notable that VDR levels were higher in GDM patients. To further define the role of vitamin D in the prophylaxis and treatment of GDM, it may be useful to conduct more extensive studies on VDR.

Background: Vitamin D3 is synthesized in skin and sequentially metabolized in liver and kidney in humans. It is well known for its function in maintaining calcium and phosphorus homeostasis and promoting bone mineralization. The primary objective of this study was to evaluate vitamin D3 level in pregnant women who were suffering from gestational diabetes mellitus and comparing it with the control groups. Materials and Methods: This case control study was conducted on 100 pregnant women who were attending the inpatient and outpatient clinics of Obstetrics department, Tanta University Hospital, who were divided into two equal groups.Group A (control group): Fifty apparently healthy pregnant women at 24th-28th weeks of gestation. Group B (study group): Fifty pregnant women had gestational diabetes. Results: There is significant increase between the two studied groups according to HbA1c, also there is decrease between the two groups as regards VIT D. Mean HbA1c % was statistically significant higher in the study group versus control group. There was statistical significant difference noted between mean serum level of vitamin D among the two studied groups. A statistically significant negative correlation was observed between serum 25 OH vitamin D and HbA1c among our cases (r=- 0.745) (p ≤ 0.001). Mean serum vitamin D was significantly lower in cases with complications than those with normal outcome. Conclusion: Vitamin D deficiency may have a positive relationship with gestational diabetes mellitus.

Background: Hypovitaminosis D has been associated with a number of adverse pregnancy outcomes, and has been recognised as a public health concern. The objective of this study was to determine the impact of Vitamin D deficiency on maternal complications like gestational diabetes mellitus (GDM) and preeclampsia (PE) among pregnant women.Methods: This was a case control study undertaken at antenatal clinics and indoor of BRD Medical College, Gorakhpur, Uttar Pradesh, India. Two maternal blood samples, one at <20 weeks and other at term along with cord blood at delivery were taken. Patients were classified into preeclampsia (n=60), gestational diabetes mellitus (n=35) and control group (n=180) after abstracting past medical records at delivery. Vitamin D was estimated by 25- Hydroxyvitamin D125 RIA kit and categorized according to ACOG criteria. Statistical analysis was done by using chi square test, binary logistic regression and Pearson’s correlation coefficient to compare between two variables. P<0.05 was considered statistically significant.Results: Out of 275 women included in the study, 78% of women were Vitamin D deficient. Mean serum vitamin D was significantly lower among preeclamptic women 11.53±6.22 ng/ml and GDM women 12.62±6.69 ng/ml as compared to controls 24.25±14.44 ng/ml (median=18.2 ng/ml) (P<0.05). Vitamin D deficiency was significantly higher in pregnant women GDM (94.28% vs 68.3%) and preeclampsia (96.67% vs 68.3%) when compared to uncomplicated group.Conclusions: Maternal vitamin D deficiency is highly prevalent in early pregnancy and is significantly associated with elevated risk for GDM and preeclampsia.

Objective To evaluate the relationship between vitamin D receptor (VDR) gene polymorphism (FokI [rs10735810]) and serum vitamin D concentration in gestational diabetes mellitus (GDM). Methods A prospective case-control study that recruited healthy pregnant women (control group) (n = 78) and women with GDM (GDM group) (n = 79), with no other comorbidities. Peripheral blood samples were collected in the 3rd trimester of gestation, and all of the pregnant women were followed-up until the end of the pregnancy and the postpartum period. Serum vitamin D concentrations were measured by high-performance liquid chromatography (HPLC). For genomic polymorphism analysis, the genomic DNA was extracted by the dodecyltrimethylammonium bromide/cetyltrimethylammonium bromide (DTAB/CTAB) method, and genotyping was performed by the polymerase chain reaction – restriction fragment length polymorphism (PCR-RFLP) technique, using the restriction enzyme FokI. The Student-t, Mann-Whitney, chi-squared, and Fischer exact tests were used for the analysis of the results. Results There was no significant difference between the pregnant women in the control and GDM groups regarding serum vitamin D levels (17.60 ± 8.89 ng/mL versus 23.60 ± 10.68 ng/mL; p = 0.1). Also, no significant difference was detected between the FokI genotypic frequency when the 2 groups were compared with each other (p = 0.41). Conclusion There was no association between the FokI polymorphism and the development of GDM, nor was there any change in serum vitamin D levels in patients with GDM.

Aims: Investigation thyroid dysfunction and autoimmunity in pregnant women with gestational diabetes mellitus. Background: This article was written to evaluate the thyroid function and anti-thyroid peroxidase (anti- TPO) antibodies in pregnant women with gestational diabetes mellitus (GDM). Method: A total of 252 women with GDM and 252 healthy pregnant women were enrolled. Thyroid tests, including TSH, FreeT3, Free T4, and anti-TPO were performed for all women at 24–28 weeks of gestation. Data analysis was then carried out using SPSS ver. 22. Result: There was a significant difference between the experimental group (38.4%) and the control group (14.06%) in terms of the prevalence of subclinical hypothyroidism (p= 0.016). The frequency of anti-TPO was higher in the experimental group than the control group and positive anti-TPO was observed in 18.6% of women with GDM and 10.3% of healthy pregnant women (P= 0.008). Conclusion: Thyroid disorders are observed in pregnant women with GDM more frequently than healthy individuals and it may be thus reasonable to perform thyroid tests routinely.

Abstract Background Gestational diabetes mellitus (GDM) is a common disease during pregnancy. The association of vitamin D receptor (VDR) polymorphisms with GDM is still controversial. This study aimed to assess the associations between VDR polymorphisms and GDM risk. Methods We searched Cochrane Library, PubMed, and Embase electronic database for all eligible studies published from Jan 1, 1980 to December 31, 2020 to conduct a Meta-analysis. We analyzed four VDR polymorphisms: BsmI (rs1544410), ApaI (rs7975232), TaqI (rs731236), and FokI (rs2228570). Inclusion Criteria: (1) The data can be evaluated; (2) case–control study; and (3) meeting the Hardy–Weinberg’s law. Exclusion criteria: (1) Insufficient or extractable data; (2) Severe publication bias in the data; and (3) duplicate publications. We eventually included 15 studies in seven articles, including 2207 cases and 2706 controls. Results We eventually included 15 studies in seven articles, including 2207 cases and 2706 controls. The data showed that ApaI (rs7975232) VDR gene polymorphism was related with the risk of GDM for the comparison of CC vs AA and recessive model in overall population and FokI (rs2228570) VDR gene polymorphism was associated with the risk of GDM for recessive model in overall population. BsmI (rs1544410) polymorphism was not related with the risk of GDM in overall population. However, in the analysis of subgroups grouped by race, BsmI (rs1544410) has certain correlations. And, the data suggested the TaqI (rs731236) polymorphism was not associated with GDM. Conclusion Based on the meta-analysis, VDR ApaI (rs7975232) and FokI (rs2228570) polymorphisms increase susceptibility to GDM. In the future, it can be used to diagnose and screen molecular biomarkers for GDM patients.
