Background: Vitamin D deficiency has been associated with an increased risk of gestational diabetes mellitus (GDM), one of the most common pregnancy complications. The vitamin D status has never previously been studied in pregnant women in Iceland. Objective: The aim of this research study was to evaluate the vitamin D status of an Icelandic cohort of pregnant women and the association between the vitamin D status and the GDM incidence. Design: Subjects included pregnant women (n = 938) who attended their first ultrasound appointment, during gestational weeks 11–14, between October 2017 and March 2018. The use of supplements containing vitamin D over the previous 3 months, height, pre-pregnancy weight, and social status were assessed using a questionnaire, and blood samples were drawn for analyzing the serum 25‑hydroxyvitamin D (25OHD) concentration. Information regarding the incidence of GDM later in pregnancy was collected from medical records. Results: The mean ± standard deviation of the serum 25OHD (S-25OHD) concentration in this cohort was 63±24 nmol/L. The proportion of women with an S-25OHD concentration of ≥ 50 nmol/L (which is considered adequate) was 70%, whereas 25% had concentrations between 30 and 49.9 nmol/L (insufficient) and 5% had concentrations < 30 nmol/L (deficient). The majority of women (n = 766, 82%) used supplements containing vitamin D on a daily basis. A gradual decrease in the proportion of women diagnosed with GDM was reported with increasing S-25OHD concentrations, going from 17.8% in the group with S-25OHD concentrations < 30 nmol/L to 12.8% in the group with S-25OHD concentrations ≥75 nmol/L; however, the association was not significant (P for trend = 0.11). Conclusion: Approximately one-third of this cohort had S-25OHD concentrations below adequate levels (< 50 nmol/L) during the first trimester of pregnancy, which may suggest that necessary action must be taken to increase their vitamin D levels. No clear association was observed between the vitamin D status and GDM in this study.

Background: Diabetes is the most common medical complication of pregnancy. Vitamin D deficiency which was initially considered only to influence bone metabolism, is now known to exert a wide spectrum of extra-skeletal effects. Vitamin D deficiency is closely associated with gestational diabetes mellitus, it also leads to adverse maternal and child outcome. Objective of this study was to compare the vitamin D levels in healthy pregnant women and women with gestational diabetes mellitus and to observe the feto-maternal outcome.Methods: This prospective study was carried out on 160 pregnant women between the age group 20-40 years attending the Obstetrics and Gynaecology department of JNMC, AMU, Aligarh from October 2016 to October 2018. Women were divided into group A- normal pregnant women and group B- women with GDM. Estimation of vitamin D was done in both the groups.Results: Mean vitamin D levels were lower in women with GDM as compared to normal pregnant women.Conclusions: Women with vitamin D deficiency have an increased risk of developing GDM and adverse feto maternal outcome as compared to those who had normal level of vitamin.

Background Vitamin D deficiency is a common occurrence, which affects maternal health during pregnancy. Evidence is accumulating for a role of a low level of vitamin D during the early pregnancy as a risk factor for the development of gestational diabetes mellitus (GDM). Our objectives are to describe the patterns of vitamin D levels in early pregnancy in mothers attending main antenatal services in Ajdabiya city, during the first quarter of the year 2017 and to examine the relationship between vitamin D levels and glucose metabolic derangements in pregnant women among the above-described population. Methods A cohort study was conducted in healthy pregnant women attending routine antenatal care in Ajdabiya city in 2017. All mothers were screened for serum 25 (OH) D level and glycated hemoglobin (HbA1c) and anthropometric by the time of booking during the first trimester (gestational age "GA" 7-15th week of pregnancy). All women with low 25 (OH) D level were screened for GDM with non-fasting post-challenge blood glucose and confirmed by OGTT according to the American Diabetes Association (ADA) classification of GDM criteria in their 2nd trimester. Data was analyzed by using SPSS, IBM 20.0. Results All mothers in the study population were Libyan, their ages ranged from 18-43 years. Parity ranged from nulliparous to P10. More than 60% of mothers were housewives while others were either working or students and considered as having an outdoor lifestyle. In the first trimester, we detected 412 mothers had serum vitamin D3 below normal, the majority of cases had deficient serum 25 (OH) D (391, 94.9%) while 21 (5.1%) women had an insufficient serum 25 (OH) D. Serum 25 (OH) D ranged from 5.9-30.0 ng/ml. In the 2nd trimester, we confirmed 43 (10.43%) pregnant women with GDM out of 391 women with deficient serum 25 (OH) D level. 25 (OH) D deficiency was statistically significant (p = 0.035, OR = 0.963, 95% CI = 0.881-0.996) and associated with all GDM cases. Conclusion We conclude that 25 (OH) D deficiency was significantly correlated with GDM, as a consequence, the deficiency of 25 (OH) D could act as a risk factor for GDM. This result implies the necessity of focusing on vitamin D3 supplementation for women of childbearing age.

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.

Of many vitamin D extraskeletal functions, its modulatory role in insulin secretion and action is especially relevant for gestational diabetes mellitus (GDM). The aims of the present study were to determine midgestational and early postpartum vitamin D status in pregnant women with and without GDM and to describe the relationship between midgestational and postpartum vitamin D status and parallel changes of glucose tolerance. A total of 76 pregnant women (47 GDM and 29 healthy controls) were included in the study. Plasma levels of 25(OH)D were measured using an enzyme immunoassay. Vitamin D was not significantly decreased in GDM compared to controls during pregnancy; however, both groups of pregnant women exhibited high prevalence of vitamin D deficiency. Prevalence of postpartum 25(OH)D deficiency in post-GDM women remained significantly higher and their postpartum 25(OH)D levels were significantly lower compared to non-GDM counterparts. Finally, based on the oGTT repeated early postpartum persistent glucose abnormality was ascertained in 15% of post-GDM women; however, neither midgestational nor postpartum 25(OH)D levels significantly differed between subjects with GDM history and persistent postpartum glucose intolerance and those with normal glucose tolerance after delivery.

Background: The prevalence of diabetes mellitus (DM) is increasing worldwide and more in developing countries like India. The diabetic epidemic experienced in India can be due to strong genetic factors coupled with increasing urbanization, sedentary lifestyle, changes in the dietary patterns and increasing obesity. Indians are at an 11-fold increased risk of developing gestational glucose intolerance and hence universal screening is essential. Uric acid is a known marker of oxidative stress. Hyperuricemia in early pregnancy may be an indicator of the existing metabolic disturbance which can hinder the maternal physiological adaptations generally seen in pregnancy thus making the pregnant women more vulnerable to the development of gestational diabetes mellitus. The objective of this study was to investigate the association between elevated uric acid levels in the first trimester of pregnancy with gestational diabetes.Methods: This prospective observational study was conducted in Chinmaya mission hospital, Bangalore from June 2016 to March 2017 (10 months). Three hundred and twelve (312) pregnant women of gestational age less than 12 weeks who attended the OBG outpatient department within this time of period for regular antenatal check-up were enrolled in the study. Along with the other antenatal investigations serum uric acid levels were estimated before 12 weeks and also between 24-28 weeks. At 24-28 weeks screening for GDM was done by OGCT using 75 gms of glucose (IADPISG criteria). Other parameters like age, parity, BMI, family history of diabetes was noted and compared.Results: In our study, among the 312 pregnant women, 88 (28%) developed GDM. Of these 74 Women (84%) with GDM had uric acid levels above 3.5 mg/dl and 14 women (15.9%) with GDM had uric acid levels below 3.5 mg/dl. Women with higher BMI showed high uric acid levels.Conclusions: Elevated serum uric acid in the first trimester has a significant correlation with development of GDM. In present study; the cut-off level of maternal serum uric acid of 3.5 mg/dl in the first trimester appears to have a good sensitivity and specificity in identifying those patients who are most likely to develop GDM later in pregnancy.

Abstract Objectives To evaluate the relationship between vitamin D levels in women with gestational diabetes and the birth weight of their newborns. Methods This is a cross-sectional study nested in a controlled clinical trial performed in a public maternity hospital in Rio de Janeiro, with a sample composed of adult pregnant women diagnosed with gestational diabetes mellitus, without other chronic morbidities. The nutritional status of vitamin D was classified as 25(OH)D, being classified as: sufficient between 30 and 100 ng/mL; insufficient: between 20 and 29 ng/mL; and deficient below 20 ng/mL. In this analysis, the data regarding the vitamin D levels at the beginning of the study (T0) of the research were considered, and the dependent variable was the birth weight. Pearson's correlation was performed to evaluate the degree of correlation between two continuous variables, being considered as a level of statistical significance the value of P < 0.05. Results The mean maternal age was 35.4 (± 5.9) years (N = 11), and among these, 18.2% (n = 2) had adequate nutritional status, 27.3% (n = 3), overweight and 54, 5% (n = 6), obesity, according to pre-gestational BMI. Among the factors admitted as a risk for hypovitaminosis D (BMI > 25kg/m², brown/black skin color, marital status (married) and occupation), 45.5% (n = 5) presented 3 or more of them. As for nutritional status of vitamin D, 63.6% (n = 7) had insufficiency, 27.3% (n = 3), deficiency and 9.1% (n = 1), sufficiency. The initial mean concentration of 25(OH)D was 21.2 n/mL. It was observed that 72.7% (n = 8) of the pregnant women presented no gestational intercurrences at delivery or in the puerperium, while 18.4% (n = 2) presented unfavorable outcomes. The mean birth weight was 2842.5 (± 1251.1) grams and the mean gestational age at birth was 36.2 (± 6.5) weeks. With respect to neonatal outcomes was observed a significant positive correlation (r = 0, 900; P = 0.037) between serum levels of 25(OH)D at baseline and birthweight. Conclusions Preliminary data indicated that best status of vitamin D is related to higher birthweight values. Funding Sources FAPERJ (FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DO RIO DE JANEIRO).

Aims: To assess vitamin D status among Gestational Diabetes Mellitus pregnant women in Gaza Strip. Study Design: Case control study. Place and Duration of Study: Samples were collected from pregnant women attending primary health care centers, Gaza, Gaza Strip. Methodology: The study comprised 90 participants, 45 GDM pregnant women and 45 apparently healthy pregnant women. Serum vitamin D and insulin levels were measured by ELISA, fasting blood glucose (FBG), 2 h oral glucose tolerance test (OGTT), glycated hemoglobin (HbA1c), triglycerides (TG), cholesterol, high-density lipoprotein (HDL), phosphorus and calcium were determined chemically. Blood pressure was measured. Body mass index (BMI) and low-density lipoprotein (LDL) were calculated. Ethical approval was acquired from Helsinki committee. All data was analyzed using the SPSS program. Results: The average vitamin D in GDM cases was lower than that in controls (P=0.031). There was an increase in the average of FBG, OGTT, HbA1c and insulin levels in GDM cases versus controls (P<0.001). The average levels of serum cholesterol, TG and LDL were significantly higher in cases as compared to controls. The average systolic and diastolic blood pressure levels were higher in GDM cases in relation to controls. Pearson correlation test showed a significant negative correlation between vitamin D and the parameters: BMI, glucose, OGTT, HbA1c and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR). Conclusion: Vitamin D was lower in GDM women compared to controls. Low vitamin D status may be associated with insulin resistance and act as a risk factor for GDM.
