Abstract Background Gestational diabetes mellitus (GDM) is a common pregnancy-induced metabolic complication worldwide. At present, a variety of strategies for diagnosis and management of GDM have been recommended. Our aim is to investigate the clinical features and pregnancy outcomes among women in whom a first-trimester fasting glucose value (≥ 5.10 mmol/L but < 7.0 mmol/L) was detected and a 2-h 75-g oral glucose tolerance test (OGTT) between 24–28 weeks was negative.Methods This is a prospective cohort study of women who registered and delivered between June 2016 and November 2019 at First Hospital, Jilin University. Pregnant women who met the inclusion criteria were categorized as normal first-trimester fasting plasma glucose(FPG)(< 5.10 mmol/L) and first-trimester fasting hyperglycemia (≥ 5.10 mmol/L but < 7 mmol/L).Outcomes included weeks at time of delivery, neonatal birth weight, Apgar score at 1 min, Apgar score at 5 min, prevalence of macrosomia, hypertensive disorders of pregnancy ,primary cesarean delivery, preterm delivery ,premature rupture of membranes and sillbirth or neonatal death were compared after women who developed gestational diabetes mellitus (GDM) were excluded.Results In our population of 2124 eligible subjects, pregnant women with first-trimester fasting hyperglycemia (≥ 5.10 mmol/L but < 7 mmol/L) constituted 20.8% of the total study population and accounted for 27.6% of subsequent GDM diagnosis. The other 1683 had a normal first-trimester FPG (< 5.1 mmol/L), accounting for 11.6% of all subsequent GDM diagnosis (p < 0.01).After excluding women with a diagnosis of GDM between 24 and 28 weeks of gestation, we observed no significant difference between groups for adverse maternal and prenatal outcomes.Conclusion More than two thirds of first-trimester fasting hyperglycemia pregnant women will have a normal OGTT performed at 24–28 week and of these women whom in no increased risk of adverse pregnancy outcomes have been identified.

Abstract Context The significance of an early diagnosis of gestational diabetes mellitus (GDM) with oral glucose tolerance test (OGTT) has not been determined. Objective The objective of this work is to investigate GDM diagnosed by early and standard OGTTs and determine adverse maternal and neonatal outcomes associated with early GDM diagnosis. Research Design and Methods The Early Diagnosis of Gestational Diabetes Mellitus study is a prospective cohort study. Each participant in the study underwent 2 OGTTs, an early OGTT at 18 to 20 gestational weeks (gws) and a standard OGTT at 24 to 28 gws. The reproduciblity between early and standard OGTT were analyzed. Maternal and neonatal metabolic disorders and pregnancy outcomes were compared across groups. Results A total of 522 participants completed both the early and standard OGTTs. The glucose values in the early OGTT were not significantly different from those in the standard OGTT (fasting: 4.31 ± 0.41 mmol/L vs 4.29 ± 0.37 mmol/L, P = .360; 1-hour: 7.68 ± 1.71 mmol/L vs 7.66 ± 1.59 mmol/L, P = .826; 2-hour: 6.69 ± 1.47 mmol/L vs 6.71 ± 1.39 mmol/L, P = .800). The reproducibility of early and standard OGTT results was 74.9%. Pregnant women in the GDM group had higher glycated hemoglobin, C-peptide, and homeostasis model assessment of insulin resistance in the late gestational period. Neonates born to mothers in the GDM group were at a higher risk of being large for gestational age (odds ratio [OR]: 3.665; 95% CI, 1.006-11.91) and were also more prone to neonatal hyperinsulinemia (OR: 3.652; 95% CI, 1.152-10.533). Conclusion Early-onset GDM diagnosed by OGTT at 18 to 20 gws is associated with maternal and neonatal metabolic disorders and adverse pregnancy outcomes. Further randomized controlled trials on the therapeutic efficacy for early-onset GDM will confirm the significance of early screening for GDM.

Chronic low-grade inflammation plays a central role in the pathophysiology of gestational diabetes mellitus (GDM). In order to investigate the ability of different <a></a><a>inflammatory blood cell parameters</a> in predicting the development of GDM and pregnancy outcomes, 258 women with GDM and 1154 women without were included in this retrospective study. First-trimester neutrophil count outperformed white blood cell (WBC) count, and neutrophil-to-lymphocyte ratio (NLR) in the predictability for GDM. Subjects were grouped based on tertiles of neutrophil count during their first-trimester pregnancy. The results showed that as the neutrophil count increased, there was a step-wise increase in GDM incidence, as well as glucose and glycosylated hemoglobin (HbA1c) level, Homeostasis Model Assessment for Insulin Resistance (HOMA-IR), macrosomia incidence and newborn weight. Neutrophil count was positively associated with pre-pregnancy Body Mass Index (BMI), HOMA-IR and newborn weight. Additionally, neutrophil count was an independent risk factor for the development of GDM, regardless of the history of GDM. Spline regression showed that there was a significant linear association between GDM incidence and continuous neutrophil count when it exceeded 5.0 × 10<sup>9</sup>/L. This work suggested that first-trimester neutrophil count is closely associated with the development of GDM and adverse pregnancy outcomes.

Background: Gestational diabetes mellitus (GDM) is a major pregnancy endocrine problem that has several confirmed risk factors and is associated with adverse pregnancy-related outcomes (PRO). Objective: To evaluate the relationship between GDM diagnosis and the associated risk factors of PRO (maternal, intrapartum, perinatal, and neonatal) in accordance with International Association of Diabetes and Pregnancy Study Groups criteria. Materials and Methods: This prospective cohort study was performed with 531 singleton parturient (265 GDM and 266 non-GDM). They were selected consecutively from referral hospitals, and the maternal, intrapartum, perinatal, and neonatal outcomes were assessed. Results: The major risk factors influencing the GDM diagnosis were maternal age, obesity, family history of diabetes, previous history of GDM, and previous history of macrosomia. In the comparison of PRO between the groups, significant associations were detected for emergency cesarean delivery, preeclampsia, polyhydramnios, premature rupture of membrane, preterm delivery, and neonatal hyperbilirubinemia in the GDM group. In the multivariate logistic regression analysis, a previous history of stillbirth was significantly associated with maternal and perinatal outcomes. The odds ratios (CI 95%) of the PRO in the women with a GDM diagnosis were: maternal = 2.43 (1.51-3.90), intrapartum = 2.05 (1.35- 3.11), perinatal = 2.00 (1.29-3.10), and neonatal = 1.68 (1.08-2.62). The PRO was significantly correlated with GDM diagnosis, but not with the risk factors. Conclusion: The adverse pregnancy outcomes were significantly correlated with GDM diagnosis, and the outcomes were not directly affected by the risk factors. Given the related adverse outcomes for mothers and offspring, early screening and management of GDM is necessary especially in Asians and in low-/middle-income countries. Key words: Gestational diabetes mellitus, Pregnancy outcomes, Risk factors.
