Active clinical trials for "Diabetes, Gestational"

Diabetes mellitus is one of the most common metabolic disorders complicating the course of pregnancy, which concerns pre-pregnancy diabetes (PGDM) - most often type 1 or type 2; and gestational diabetes (GDM) - treated with diet (G1) or insulin (G2). Currently, in the pathogenesis of diabetes and the regulation of glucose metabolism, the role of tissue hormones, including adipokines, e.g., omentin-1, visfatin, have been considered. Adipokines might also affect the development of the fetus - mainly fetal adipose tissue gain. Their concentrations and activity depend on the maternal visceral fat content and concomitant metabolic disorders. It is known that adipokines are excreted in human milk during the lactation period. The aim of the study was to assess the impact of diabetes during pregnancy, requiring treatment with diet or insulin, on the nutritional status of the newborn.

The researchers investigated nineteen pregnant women in third trimester and again postpartum. At the experimental days we performed a mealtest and drew blood for analyses of glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), insulin, C-peptide and glucagon. The researchers aimed to investigate whether women with gestational diabetes mellitus exhibit decreased postprandial GLP-1 responses, and if so, whether this deficiency ceases following delivery when normal glucose tolerance is reestablished.

Gestational Diabetes Mellitus (GDM) has long been known as leading to macrosomias, neonatal hypoglycemias and other complications which are treatable and preventable. Nowadays, GDM is recognized as an entity with long-term serious sequels to the mother (GDM is considered a forerunner of type 2 diabetes) and her offspring. Indeed, according to the programming hypothesis, GDM sets the stage for metabolic syndrome, obesity, type 2 diabetes and hypertension. However, these cross-sectional studies failed to control for maternal disease history and genetic background although heredity is a major epidemiology risk factor of type 2 diabetes. Also, studies usually refer to traditional markers such as BMI, blood pressure, lipids profile and oral glucose tolerance test (OGTT); none explored inflammatory biomarkers and adipokines in-depth, despite the possible link between their presence and the development of metabolic and cardiovascular diseases in GDM offsprings. Exclusion of genetic confounding factors will help establish the role of GDM as an independent marker of cardiometabolic risk in GDM offspring. It is highly relevant to identify GDM as a risk factor for cardiometabolic diseases, given the worldwide obesity epidemic, the alarming prevalence increase of GDM and its serious sequels to both mother and offspring.

This study was conducted to analyze the role of TSH level and TPOAb status in early pregnancy and use this information in assessment of the risk of gestational diabetes mellitus at different weeks of gestation when the FT4 level is normal.

Our study will assess if there is a difference in incidence of gestational diabetes using different screening approaches, either using a one-step approach with a 2 hour glucose tolerance test or using a two-step approach. Prior studies have proven similar incidences including a randomized controlled trial.

Aim for this study is to measure the prevalence of Gestational Diabetes Mellitus (GDM) using World Health Organisation (WHO) versus International Association of Diabetes in Pregnancy Study Group (IADPSG) criteria among pregnant mother in Universiti Kebangsaan Malaysia Medical Centre (UKMMC)

Assess postpartum diabetes screening in GDM patients with initiation of a reminder system in the postpartum period

Background: The microbiota-dependent metabolite trimethylamine-N-oxide (TMAO) has been reported as a novel and independent risk factor for the development of cardiovascular and metabolic diseases, but the association with gestational diabetes mellitus (GDM) remains unclear. Objective: To investigate the association between plasma TMAO concentration and GDM in a two-phase study. Design: The initial discovery phase included 866 pregnant women (433 GDM cases and 433 matched controls) in Wuhan China. Study participants were recruited from pregnant women who attended the outpatient clinics of the Department of Endocrinology, Tongji Hospital, to screen for GDM between August 2012 and April 2015, or pregnant women who visited the Hubei Maternal and Child Health Hospital or the Central Hospital of Wuhan for a routine antenatal checkup from May 2014 to November 2016. The inclusion criteria of participants were: age ≥ 20 years, gestational age between 24 and 32 weeks, no history of a diagnosis of diabetes or gestational diabetes, and no history of receiving pharmacological treatment known to affect glucose metabolism. An independent replication phase study was nested within an ongoing prospective cohort study, namely the Tongji Maternal and Child Health Cohort (TMCHC). Beginning in January 2013, women receiving prenatal care prior to 16 weeks of gestation were invited to join the TMCHC. Exclusion criteria included pre-pregnancy diabetes, clinically significant neurological, endocrinological or other systemic diseases and multiple pregnancies. All enrolled pregnant women received a regular prenatal checkup in hospital and underwent an oral glucose tolerance test (OGTT) during 24-32 weeks of gestation to screen for GDM. 276 members who developed GDM before May 2016 and had fasting blood collected before 20 weeks'gestation were included as cases in this analysis. Two controls were individually matched to each case from among women without GDM. These two studies were approved by the ethics committee of Tongji Medical College. All the participants gave informed written consent before they were included in the study. Plasma TMAO concentrations were determined by stable isotope dilution liquid chromatography with online electrospray ionization tandem mass spectrometry.

The main purpose of the study is to evaluate an OGTT at 18 to 20 gestational weeks as an early diagnosis method of GDM in low risk pregnant women. By investigating maternal and neonatal outcomes that are associated with the early OGTT and regular OGTT results, the study will provide a evidence for the most appropriate time to perform an OGTT in pregnant women.

The purpose of this study is to determine whether unrecognized maternal hyperglycemia and postprandial lipemia early or late in gestation predicts excess neonatal adiposity.
