The Difference

Background. Gestational diabetes mellitus (GDM) is a severe threat to the health of both mother and child. The pathogenesis of GDM remains unclear, although much research has found that the levels of hydrogen sulfide (H2S) play an important role in complications of pregnancy. Methods. We collected venous blood samples from parturient women and umbilical vein blood (UVB) and peripheral venous blood (PVB) samples one hour after childbirth in the control, GDM-, and GDM+ groups in order to determine the concentration of glucose and H2S in plasma; to measure levels of TNF-α, IL-1β, IL-6, TGF-β1, and ADP in parturient women and the UVB of newborns; and to find the correlation of H2S with regression. Results. We found that, with the elevation of glucose, the level of H2S was decreased in GDM pregnant women and newborns and the concentrations of IL-6 and TNF-α were upregulated. With regression, IL-6 and TNF-α concentrations were positively correlated with the level of blood glucose and negatively correlated with H2S concentration. Conclusion. This study shows that downregulation of H2S participates in the pathogenesis of GDM and is of great significance in understanding the difference of H2S between normal and GDM pregnant women and newborns. This study suggests that IL-6 and TNF-α are correlated with gestational diabetes mellitus. The current study expands the knowledge base regarding H2S and provides new avenues for exploring further the pathogenesis of GDM.

Purpose. To explore whether pregnant women with gestational diabetes mellitus (GDM) had cognitive impairment and assess cognitive function in normal pregnant women. Methods. A total of 75 consecutive women diagnosed with GDM (GDM group), 70 normal pregnant women (NP group) without diabetes and matched for age, and 51 female volunteers (CG group) with the similar age level, normal blood glucose, and nonpregnancy were included in the study. For the assessment of cognitive functions, Montreal Cognitive Assessment (MoCA) was performed. Venous blood samples were collected to measure blood glucose, glycated hemoglobin (HbA1c), methylglyoxal (MGO), beta amyloid (Aβ), and tau protein. Results. The score of MoCA of GDM was lowest, and the score of the NP group was lower than volunteers ( P < 0.05 ). The incidence of cognitive dysfunction increased significantly in the GDM group with statistical significance ( P < 0.05 ). The levels of tau and MGO in the GDM group were significantly less than those in the NP and CG groups, and Aβ in the GDM group was significantly more than that in the NP and CG groups ( P < 0.05 ), but the differences between NP and CG groups were not statistically significant ( P < 0.05 ). Conclusion. The pregnant women with GDM showed a significant decline in cognitive function, and the normal pregnant women also showed a decline in cognitive function which is very light.

Abstract Background Gestational diabetes mellitus (GDM) is a metabolic disease that occurs in pregnant women and increases the risk for the development of diabetes. The relationship between GDM and meconium microbiota and metabolome remains incompletely understood. Methods Four hundred eighteen mothers (147 women with GDM and 271 normal pregnant women) and their neonates from the GDM Mother and Child Study were included in this study. Meconium microbiota were profiled by 16S rRNA gene sequencing. Meconium and maternal serum metabolome were examined by UPLC-QE. Results Microbial communities in meconium were significantly altered in neonates from the GDM mothers. A reduction in alpha diversity was observed in neonates of GDM mothers. At the phylum level, the abundance of Firmicutes and Proteobacteria changed significantly in neonates of GDM mothers. Metabolomic analysis of meconium showed that metabolic pathways including taurine and hypotaurine metabolism, pyrimidine metabolism, beta-alanine metabolism, and bile acid biosynthesis were altered in GDM subjects. Several changed metabolites varying by the similar trend across the maternal serum and neonatal meconium were observed. Conclusion Altogether, these findings suggest that GDM could alter the serum metabolome and is associated with the neonatal meconium microbiota and metabolome, highlighting the importance of maternal factors on early-life metabolism.

The aim of this study was to determine the release and regulation of leptin, resistin and adiponectin from human placenta and fetal membranes, and maternal subcutaneous adipose tissue and skeletal muscle obtained from normal and gestational diabetes mellitus (GDM)-complicated pregnancies at the time of Cesarean section. Tissue explants were incubated in the absence (basal control) or presence of 10 μg/ml lipopolysaccharide (LPS), 10, 20 or 40 ng/ml tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and IL-8, 1 μM phorbol myristate acetate, 10, 20 and 40 mM glucose, 0.1, 1 and 10 μM insulin and 0.1 1 and 10 μM dexamethasone, progesterone and estrogen. After an 18-h incubation, the medium was collected and the release of leptin, resistin and adiponectin was quantified by ELISA. Human gestational tissues and maternal tissues released immunoreactive leptin, resistin and adiponectin; however, there was no difference in the release of either resistin or adiponectin between normal pregnant women and women with gestational diabetes. The release of leptin was significantly higher in placenta, amnion and choriodecidua obtained from normal pregnant women compared with women with GDM. However, in maternal tissues, the situation was reversed, with adipose tissue and skeletal muscle obtained from women with GDM releasing significantly greater amounts of leptin. In adipose tissue and skeletal muscle the release of leptin was significantly greater in insulin-controlled GDM compared with diet-controlled GDM, and leptin release from adipose tissue was significantly correlated with maternal body mass index. In all tissues tested, there was no effect of incubation with LPS, IL-6, IL-8 or TNF-α on leptin, resistin or adiponectin release. PMA significantly increased the release of resistin from placenta and adipose tissue. Insulin increased placental resistin release, whereas the hormones dexamethasone, progesterone and estrogen significantly decreased placental resistin release. The data presented in this study demonstrate that dysregulation of leptin metabolism and/or function in the placenta may be implicated in the pathogenesis of GDM. Furthermore, resistin release is greatly affected by a variety of inflammatory mediators and hormones.

Objective: To determine the vitamin B12 deficiency and dyslipidemia in Gestational Diabetes mellitus (GDM) diagnosed pregnant women. Study Design: Observational study. Setting: Department of Biochemistry and Gynecology/Obstetrics LUMHS Hospital Jamshoro. Period: January 2018 to December 2018. Material & Methods: A sample of 216 diagnosed GDM pregnant women was selected according to study criteria. Venous blood samples were centrifuged to separate sera; that were used for the estimation of (hexokinase method), blood lipids and Vitamin B12 (ECLIA assay method) by Cobas chemistry analyzer. Statistical SPSS software 21.0 (IBM, Inc USA) was used for study research variables at 95% CI (P ≤ 0.05). Results: Age of GDM cases was 36.12±9.5 years. Mean+/-SD vitamin B12 level was noted 154.7±81.7 ng/mL (P=0.0001). Serum cholesterol, triglycerides and LDLc were elevated and HDLc was low in GDM cases (P=0.0001). Of 216 GDM cases, vitamin B12 deficiency was present in 152 (70.3%) (P=0.0001) and dyslipidemia in 50 (23.1%) (X2=452.0) (P=0.0001). Vitamin B12 shows inverse correlation with RBG (r= -0.41, P=0.005), CHOL (r= -0.25, P=0.024), TAG (r= -0.81, P=0.0001), LDLc (r= -0.797, P=0.0001) and positive correlation with HDLc (r= 0.76, P=0.0001). Conclusion: The present study finds vitamin B12 deficiency in 152 (70.3%) and dyslipidemia in 50 (23.1%). Vitamin B12 deficient GDM women show high cholesterol, triglycerides, LDLc and low HDLc. Hence, it is concluded, the vitamin B12 deficiency is linked with dyslipidemia in Gestational Diabetes mellitus.

Insulin resistance in gestational diabetes increases maternal and fetal complications. Tumor necrosis factor-alpha (TNF-α) is an inflammatory factor associated with insulin resistance. The aim of this study was to determine the association between pregnancy serum TNF-α level and postpartum insulin resistance in patients with gestational diabetes mellitus. 50 pregnant women, including 25 cases of gestational diabetes and 25 healthy pregnant women, were evaluated. First, during the third trimester of pregnancy, serum TNF-α level of all cases were measured. Two months after delivery, based on the obtained results from insulin levels and a 2-hour glucose tolerance test, HOMA-IR and HOMA-B were calculated, and the association between serum TNF-α level and insulin resistance was determined. Data were analyzed using independent t-test, Mann-Whitney, and chi-square test in SPSS software. The mean serum level of TNF-α in women with gestational diabetes mellitus was higher than healthy subjects, but there was no significant difference between the two groups. The serum level of insulin, HOMA-IR and HOMA-B indices in women with gestational diabetes mellitus were higher than healthy subjects, with a significant difference in all of the measures between two groups (P=0.0001). There was no significant correlation between TNF-α and HOMAIR levels in insulin-resistant mothers two months after delivery (r=−0.33). Also, no significant correlation was detected between pregnancy TNF-α levels and HOMA-B index. Despite the higher serum levels of insulin, HOMA-IR, and HOMA-B in the diabetic group, the serum TNF-α level did not show any correlation with insulin resistance after delivery.

Preeclampsia (PE) and gestational diabetes mellitus (GDM) are the most common complications of pregnancy, which result in adverse outcomes for the mother and the fetus. GDM is regarded as a separate independent risk factor for PE development, as evidenced by a higher preeclampsia rate in gestational diabetes mellitus than in the general population. The role the endothelial cell dysfunction plays is considered to be the most reasonable one in the origin of these diseases. The activity of plasma and tissue angiotensin converting enzyme (ACE) is believed to be genetically controlled. The available data suggests that increased ACE activity due to deletion (D)/insertion (I) in the 16th intron of ACE gene, which is called ACE gene I/D polymorphism, is associated with preeclampsia and varies depending on the studied population and the geography. We did not find any literature data that estimates the influence of ACE gene I/D polymorphism on PE rate in pregnant women with GDM. Therefore, the present study aimed to investigate a relationship between ACE gene I/D polymorphism and preeclampsia development in the case of GDM in the Russian population. The study used the genomic DNA derived by phenol-chloroform extraction method from venous blood samples in 137 pregnant women, including samples of 74 women with GDM accompanied with PE and the blood samples of 63 women with GDM w/o preeclampsia. Genotyping of insertion/deletion in the I/D region (16 intron of АСЕ gene) was conducted by real-time PCR using the TaqMan competing probe technology. The particular features in the frequency array of alleles and genotypes of the ACE gen I/D polymorphism under review, as associated with preeclampsia development risk in pregnant women with GDM, were identified. The acquired data testify to the need to further study of ACE gene I/D region polymorphism association in a large patient sample taking into account the PE and GDM risk factors estimated in the clinical practice.

The Difference

Background: Adiponectin and Leptin are adipokines produced by adipocytes. TNF-alpha and IL-6 are inflammatory cytokines which increases insulin resistance. Decreased adiponectin, increased leptin, TNF-alpha and IL-6 is associated with risk of Gestational Diabetes Mellitus, characterised by glucose intolerance that begins or first recognised in pregnancy leading to maternal and foetal complications. India has a high prevalence of GDM upto 16.55% by (2hr plasma glucose of more than 140mg/dl). We aimed to evaluate whether ‘First trimester serum biomarkers predict gestational diabetes mellitus’. The objective of the study was to study the serum biomarkers levels in early pregnancy and predict the risk of developing gestational diabetes mellitus. To study the correlation of serum biomarkers levels in gestational diabetes mellitus.Methods: The study was conducted between October 2014 to March 2016 in healthy pregnant women aged 20-35 yrs attending the antenatal OPD in ESIC Hospital. Study design: Prospective observational study with three study groups 1. NGT, 2. GDM1, 3. GDM2 with two-time points one at first trimester and other second trimester. Sample size: 125 pregnant women. Work plan: Demographics, baseline characteristics and other clinical risk factors of pregnant women in 1st trimester who consented for the study, meeting the inclusion criteria are noted. 75 gm OGCT (oral glucose challenge test) done at two-time points first and second trimester in the study groups will be analysed using the DIPSI criteria with a cut-off value ≥140mg/dl and divided into 3 groups. Serum biomarkers were measured by DRG ELISA method at one-time point in first trimester in all the 3 groups.Results: The serum levels of adiponectin are comparatively reduced in first trimester GDM1 group. As the difference was not significant with p-value of 0.33 there was no correlation between adiponectin and GDM in our study. Serum leptin is increased in second trimester GDM group but the difference is insignificant with a p value of 0.11 showing no correlation.Conclusions: Among the cytokines IL-6 also shows an increasing tendency in both GDM1 (5.9±0.57) and GDM2 (6.04±1.04) groups compared to the NGT (5.82±0.38) group. Serum TNFα is increased in GDM1 (17.29±17.14) and NGT (17.03±24.03) compared to GDM2 (13.54±17.29) group.
