Objective: Aims of the study is to specify the significance of thiol/disulfide homeostasis in the aspect of gestational diabetes mellitus (GDM) and GDM-related complications. Material and Methods: This study is a prospective review of the data of 61 healthy and non-pregnant women, 58 healthy pregnant women, and 62 pregnant women with GDM. Results: The patients with gestational diabetes mellitus had significantly higher disulfide/native thiol and disulfide/total thiol concentrations than non-pregnant patients (p<0.001 for both) and healthy pregnant patients (p: 0.015 and p: 0.018, respectively). Besides, in GDM group had significantly lower native thiol/total thiol concentrations than non-pregnant patients and healthy pregnant patients (p<0.001 and p: 0.016, respectively). There were positive and significant correlations between disulfide levels and HbA1c concentrations (r=0.26, p: 0.042), and between disulfide and oral glucose tolerance test first hour concentrations (r=0.26, p: 0.039). The receiver operating characteristic curve analyses for native thiol, total thiol, and disulfide were unable to predict adverse perinatal outcomes in this cohort. Conclusion: The significantly higher concentrations of disulfide/native thiol and disulfide/total thiol in women with GDM could be considered as the presence of increased oxidative stress.  However, these markers failed to predict adverse perinatal outcomes.

Uric acid (UA) levels are associated with many diseases including those related to lifestyle. The aim of this study was to evaluate the influence of clinical and anthropometric parameters on UA and xanthine (X) levels during pregnancy and postpartum in women with physiological pregnancy and pregnancy complicated by gestational diabetes mellitus (GDM), and to evaluate their impact on adverse perinatal outcomes. A total of 143 participants were included. Analyte levels were determined by HPLC with ultraviolet detection (HPLC-UV). Several single-nucleotide polymorphisms (SNPs) in UA transporters were genotyped using commercial assays. UA levels were higher within GDM women with pre-gestational obesity, those in high-risk groups, and those who required insulin during pregnancy. X levels were higher in the GDM group during pregnancy and also postpartum. Positive correlations between UA and X levels with body mass index (BMI) and glycemia levels were found. Gestational age at delivery was negatively correlated with UA and X levels postpartum. Postpartum X levels were significantly higher in women who underwent caesarean sections. Our data support a possible link between increased UA levels and a high-risk GDM subtype. UA levels were higher among women whose glucose tolerance was severely disturbed. Mid-gestational UA and X levels were not linked to adverse perinatal outcomes.

Gestational diabetes mellitus (GDM) is a serious medical and social problem, because it greatly increases the frequency of adverse pregnancy outcomes for mother and fetus. The frequency of GDM in the general population of different countries varies from 1% to 14% and average 7%, in Russia this figure is estimated at 4.5%. Aim. To evaluate the prevalence of GDM in Ryazan Regional clinical perinatal center for the last 3 years and examine its influence on the course and outcome of pregnancy. Materials and Methods. The analysis of the birth history data and exchange cards of 1690 pregnant women from 2015 to 2017 at Ryazan Regional clinical perinatal center. Results. GDM was diagnosed in 193 women (prevalence – 11.4%), with 62 pregnant women on the basis of the results of oral glucose tolerance test performed in the period of 24-30 weeks. It was established that the course of pregnancy and delivery in patients with GDM was characterized by a high percentage of complications (late gestosis – 18.1%, anemia – 11.3%, swelling – 11.9%, early toxicosis – 4.6%, poly-hydramnios – 12.4%, chronic pyelonephritis – 5.1% and threatened miscarriage – 3.6%). Pregnancy outcome study revealed that the majority – 60.6% of pregnancies ended in natural births. Preterm birth was noted in 15% of cases, of which 2 cases were of perinatal fetal death. The frequency of delivery by cesarean section – 39.4%. The frequency of childbirth large fetus was 21.8%, higher than in women with normal blood glucose levels. Conclusions. The prevalence of GDM in Ryazan Regional clinical perinatal center for the last 3 years was 11.4%. Complications during pregnancy were observed in 153 women (79.2%) of with GDM. The most frequent complications were; late gestosis, pregnancy anemia, edema, early toxemia, polyhydramnios, chronic pyelonephritis, and threatened miscarriage. In pregnant women with GDM, adverse outcomes of pregnancy were more common than in women with normoglycemia. Significant differences were obtained in the frequency of premature birth, macrosomia of the fetus and asphyxia during childbirth.

Background: Gestational diabetes mellitus (GDM) is carbohydrate intolerance at the onset of pregnancy which induces pathological short term or long term outcomes for both mother and baby. The aim of the present study was to know the prevalence of GDM in pregnant women who were attending the antenatal care (ANC) center at a tertiary care hospital in Kolar, Karnataka, India.Methods: This prospective study was conducted in Department of Obstetrics and Gynecology, Sri Devaraj Urs Medical College, a constituent of Sri Devaraj Urs Academy of Higher Education and Research, Kolar, Karnataka, India. The duration of the study was two months. In this study, 108 pregnant women above 24 weeks of gestation were screened for GDM by oral glucose tolerance test. Fasting 2 milli liter blood was collected and were given 75 grams of glucose in 200 milli liters of water and asked to drink within 5 minutes. Again 2 milli liters venous blood was collected after 1 hour and 2 hours from all participants. Plasma sample was used for the estimation of glucose by glucose oxidase and peroxidase (GOD-POD) method.Results: Out of 108, 12 women (11.1%) were diagnosed with GDM. The prevalence rate was higher in the age group of 26-30 years (41.6%).  Among 12 diabetic women, five (47.2%) exercised regularly and seven (58.3%) did not doing exercise. Out of 12 GDM subjects, eight of them had family history of diabetes in first degree relatives; among which one was hypertensive and five were suffering from thyroid problems.Conclusions: In the present study, the prevalence of GDM was found to be 11.1%. Prevalence of GDM might be influenced by increasing age, pre pregnancy weight, family history of diabetes, past history of pregnancy complications, status of literacy and exercise.

Objective.To determine plasma markers of oxidative stress during the second and third trimester of pregnancy in patients with gestational diabetes mellitus (GDM).Study Design.We conducted a prospective nested case-control study involving 400 pregnant women, 22 of whom developed GDM. As control group, 30 normal pregnant women were chosen randomly. Plasma samples were analyzed for 8-iso-prostaglandin F2α(8-iso-PGF2α), advanced oxidative protein products (AOPPs), protein carbonyl (PCO), glutathione peroxidase-3 (GPX-3), and paraoxonase-1 (PON1) at 16–20 weeks, 24–28 weeks, and 32–36 weeks of gestation.Results.Compared to control subjects, the plasma levels of PCO, AOPPs, and 8-iso-PGF2αwere elevated at 16–20 weeks’ and 32–36 weeks’ gestation in GDM. There was no significant difference in PCO and 8-iso-PGF2αat 24–28 weeks in GDM. GPX-3 was statistically significantly increased at 16–20 weeks and 32–36 weeks in GDM. PON1 reduced in patients with GDM. No significant differences were found at 24–28 and 32–36 weeks between the GDM and control groups. In GDM, PCO, AOPPs, and 8-iso-PGF2αlevels were higher and GPX-3 and PON1 levels were lower in the second than the third trimester.Conclusion.Oxidation status increased in GDM, especially protein oxidation, which may contribute to the pathogenesis of GDM.

ObjectiveProgranulin (PGRN) was recently introduced as a novel marker of chronic inflammatory response in obesity and type 2 diabetes capable of directly affecting the insulin signaling pathway. This study aimed to investigate the role of PGRN in gestational diabetes mellitus (GDM), which is regarded as a model for early type 2 diabetes.MethodsPGRN serum levels were measured in 90 pregnant women (45 GDM and 45 normal glucose tolerance (NGT)). In addition, PGRN was measured during a 2-h, 75 g oral glucose tolerance test in 20 pregnant women (ten GDM and ten NGT) and in 16 of them post partum (ten GDM and six NGT).ResultsPGRN concentrations were significantly higher in pregnant women compared with post partum levels (536.79±31.81 vs 241.53±8.86, P<0.001). Multivariate regression analyses showed a strong positive correlation of PGRN with estrogen and progesterone. The insulinogenic index, a marker of early insulin secretion, displayed a positive correlation with PGRN, both during and after pregnancy (R=0.47, P=0.034; R=0.63, P=0.012). HbA1c and the oral glucose insulin sensitivity index showed significant post partum associations with PGRN (R=0.43, P=0.049; R=−0.65, P=0.009).ConclusionsPGRN concentrations are markedly lower after pregnancy regardless of the gestational glucose tolerance state. PGRN levels per se do not discriminate between mild GDM and NGT in pregnant women. Therefore, the development of GDM appears to be due to impaired β-cell function that is not related to PGRN effect.

Background: To study the prevalence of gestational diabetes mellitus among antenatal mothers and to assess the importance of universal screening to detect gestational diabetes mellitus (GDM).Methods: A total of 300 antenatal women irrespective of gestational age were screened for GDM at their antenatal visit during the period of January 2020 to June 2020. All women were screened with 75gm oral glucose load irrespective of last meal followed by blood glucose estimation by glucose oxidase peroxidase method 2 hours following glucose load. A cut-off of 140mg/dl or more were labelled as gestational diabetes mellitus as per DIPSI guidelines.Results: Out of 300 antenatal women tested, 24 women (8%) were positive for gestational diabetes mellitus. During the first, second and third trimesters 12.5%, 33.33% and 54.17% were diagnosed with gestational diabetes mellitus respectively. The number of gestational diabetes mellitus patients for the age groups ≤20 years, 21-25 years, 26-30 years and >30 years are 2 (8.33%), 3 (12.5%), 8 (33.33%) and 11 (45.83%) respectively. The number of pregnant women tested positive for gestational diabetes mellitus with BMI ≤18.5, 18.6-24.9, 25-29.9 and 30-35 are 2 (8.33%), 4(16.67%), 8(33.33%) and 10(41.67%) respectively.Conclusions: Prevalence of GDM in our study is 8%. About 29.16% of GDM did not have any risk factors. This emphasizes the importance of universal screening for GDM of all pregnant women irrespective of gestational age. There is an increased association of GDM with age, BMI, family history and parity according to our study.
