Ursodeoxycholic Acid vs Metformin in Gestational Diabetes Mellitus
Gestational DiabetesGUARD is a Clinical Trial that wants to explore the impact of UDCA compared to metformin in the treatment of GDM. The trial wants to recruit 158 women who are overweight or obese who have been diagnosed with GDM, and require pharmacological treatment. Glucose control is our primary measure. Each year in the UK approximately 35,000 women develop diabetes during pregnancy, a condition called gestational diabetes mellitus (GDM), which increases the risk of adverse outcomes for both mother and child. Metformin, although unlicensed for used in pregnancy, is the most commonly used first line pharmacological treatment. However, there is increasing concern about its widespread use during pregnancy, because of its limited efficacy and because of potential safety concerns. Other common treatments have not been shown to be superior. Therefore, there is an unmet need for additional therapies. Ursodeoxycholic acid (UDCA) is commonly used in pregnancy for the treatment of intrahepatic cholestasis of pregnancy. It is currently not an established/licensed treatment for GDM. However data from observational studies of women with cholestasis in pregnancy has flagged this to be a potential effective treatment to control blood glucose levels in GDM. The investigators will ask women to attend three study visits, which will coincide with the time of their antenatal appointments. The trial aims to collect a range of clinical and research blood samples, to measure quality of life and treatment satisfaction through two questionnaires, and will will ask women to wear a continuous glucose monitor for three 10 day periods. There will be a number of optional assessments that participants will be offered. The primary outcome will be the fasting blood glucose concentration at 36 weeks of gestation. The investigators intend to carry out this study at 3 sites in the United Kingdom (Guy's and St Thomas, Imperial College and Nottingham), and it has been funded by a J.P Moulton Foundation grant.
Glycemic Control After Antenatal Corticosteroids in Women With Pregestational and Gestational Diabetes...
Diabetes MellitusType 25 moreThere is a fundamental gap in understanding the maternal and neonatal effects of antenatal corticosteroid (ACS) administration in women with threatened preterm birth (PTB) who have diabetes. Since the initial discovery of ACS for neonatal benefit in 1972, more than 40 randomized controlled trials have been performed evaluating its efficacy. However, none of these trials have included women with T2DM, and there is limited data among women with gestational diabetes. While ACS have been shown to reduce neonatal morbidity associated with PTB in non-diabetic women, the side effects of ACS (maternal hyperglycemia and fetal hyperinsulinemia) may mitigate the neonatal benefit of ACS in women with diabetes. Before neonatal benefit of ACS can be evaluated in this population, the first step is to optimize maternal glycemic control after ACS. Previous studies evaluating maternal hyperglycemia after ACS have been limited by small sample size, retrospective study design, or insufficient glucose data. Use of continuous glucose monitoring (CGM) in a randomized clinical trial provides a unique opportunity to overcome these challenges. Our long-term goal is to improve maternal and child health among women with diabetes as an independently funded clinical researcher. The research objectives of this proposal are to test the efficacy of three treatment strategies at achieving maternal glycemic control after ACS and evaluate the association between maternal glycemic control and neonatal outcomes. Our central hypothesis is that treatment with a continuous insulin infusion will improve maternal glycemic control, which is key to improving neonatal outcomes, but at the cost of less patient satisfaction and more health resource utilization. This hypothesis will be tested by pursuing the following specific aims: 1) Test the efficacy of three treatment strategies (addition of sliding scale insulin, up-titration of home insulin, and continuous insulin infusion) at achieving maternal glycemic control after ACS and 2) Quantify the association between maternal glycemic control after ACS and neonatal morbidity. Completion of these aims will determine the optimal strategy to achieve maternal glycemic control after ACS and inform a larger, multicenter trial to improve neonatal outcomes among women with diabetes and threatened PTB.
A Pragmatic Randomized Controlled Trial of Health Impact of Pistachios on Women With Gestational...
Gestational Diabetes Mellitus in PregnancyGestational diabetes mellitus (GDM) is the hyperglycemia with first onset or recognition during pregnancy, of which prevalence has been sharply increased worldwide in the past decades. Nuts offer numerous health benefits, mainly in relation to cardiovascular diseases as well as other chronic conditions. Pistachios have a balanced nutrition profile with lower fat [polyunsaturated fatty acids (PUFAs) and monounsaturated fatty acids (MUFAs)], higher protein, fiber (both soluble and insoluble), potassium, phytosterols, γ-tocopherol, vitamin K, xanthophyll carotenoids and rich antioxidant phytochemical constituents (stigmasterol, campesterol, resveratrol, catechins, lutein and zeaxanthin). Recent researches have found that nutritional intervention of the Mediterranean diet with an enhanced consumption of extra virgin olive oil and pistachios lowered incidence of GDM and other adverse outcomes (urinary tract infections, emergency C-sections, perineal trauma, large-for-gestational-age and small-for gestational age newborns) for pregnant women. Another clinical trial compared the acute metabolic effect of pistachios and isocaloric whole-wheat bread in women with GDM, finding significantly improved glucose and insulin responses, higher GLP-1 and lower gastric inhibitory polypeptide (GIP) levels in those consuming pistachios. However, more compelling evidences are still in need to throw light on the long-term effects of pistachio consumption on maternal and offspring's outcomes for GDM patients. Besides, effects of pistachios on the thorough metabolic profile of GDM patients also need to be elucidated. This study aims to further demonstrate the long-term health effects of pistachio consumption on glycemic control, lipid profile, gut hormone responses, inflammatory condition and pregnancy outcomes for women with GDM. The clinical study is a randomized, controlled, two-arm, parallel trial from the diagnosis of gestational diabetes to delivery consisting of six study visits including screening/consent. A total of 80 singleton pregnant women with confirmed diagnosis of GDM will be consecutively recruited, all with the pregestational body mass index (BMI) greater than 24 kg/m2. All subjects will be randomly assigned to intervention group (IG) or stand care control group (CG)), in an allocation ratio of (1:1) in blocks. According to the Chinese nutritional guidelines for GDM women, the energy intake of 1500-1800 kcal/d will be recommended for the included women with pregestational BMI≥24 kg/m2. Standard care and a balanced diet will be recommended to the women in CG incorporating the total nuts intake of less than 2.5 oz per week). While the women in the IG will be offered the otherwise same diet as their counterparts in the CG, except for the extra intake of pistachios of 1.5 oz thrice per week. All participants will be followed up in 2 weeks initially and then once every 4-6 weeks until delivery or termination of pregnancy. The effect of different interventions on the glycemic profile (the continuous glucose monitoring (CGM) plus self-monitoring), lipid profile, gut hormone responses, inflammatory factors and metabolomics profiling (multi-omics data) will be monitored and compared. The pregnant outcome of the two groups will be also followed up and compared eventually. With all data reviewed and analyzed, this study will add evidence to the long-term health effect of pistachios on GDM women.
SPARK- a Digital Platform to Improve Self-management of Gestational Diabetes
Gestational Diabetes MellitusGestational diabetes mellitus (GDM) is an increasing public health challenge. Innovative, effective and scalable lifestyle interventions to support women with GDM to manage their disease and to prevent adverse obstetric and neonatal outcomes as well as later morbidity are requested.The aim of this project is to evaluate whether a novel, mobile health (mHealth) platform (SPARK) can improve self-management of GDM and prevent adverse maternal and offspring outcomes. SPARK is a multi-centre randomised controlled trial recruiting women diagnosed with GDM in South Eastern Sweden. Women will be randomised to the control or intervention group. All women will receive standard care. The intervention group will also receive support through the SPARK platform for healthy eating, physical activity and glycaemic control. Pregnancy outcomes are glycaemic control (primary), diet, physical activity, metabolic and inflammatory biomarkers in gestational week 36-37 as well as adverse obstetric and neonatal outcomes. Secondary outcomes also include cardiometabolic risk, physical activity and healthy eating behaviours one-year postpartum.

Efficacy of Treatment for Gestational Diabetes Diagnosed by the IADPSG Criteria.
Gestational DiabetesThere is a lack of international uniformity in the approach to the screening and diagnosis of gestational diabetes mellitus (GDM). The new diagnostic criteria by the International Association of Diabetes and Pregnancy Study Groups (IADPSG) based on data from the study of Hyperglycemia and Adverse Pregnancy Outcomes (HAPO) have created controversy because of the lack of clinical evidence of treatment benefit for mild GDM and the treatment effects on perinatal outcomes. The purpose of the present study is to know the efficacy of treatment to reduce adverse pregnancy outcomes in Mexican women diagnosed with GDM by IADPSG criteria.
The Impact of Glycemic Index Education on Lowering Dietary GI in Gestational Diabetes Mellitus
Gestational Diabetes MellitusGestational Diabetes Mellitus (GDM) incidence is increasing worldwide, and within Canada, the Atlantic provinces statistically have been found to have highest prevalence of diabetes. Increasing evidence supports the benefit of following a low glycaemic index (GI) diet in GDM and the Canadian Diabetes Guidelines recommends replacing high GI foods for low GI foods. Despite recommendation to adapt a low GI diet in GDM, there are limitations and barriers recognized to GI utility largely focused on knowledge translation. There is sufficient research to support a low GI diet in benefiting outcomes of GDM, therefore the GI in GDM Online trial will investigate the feasibility and effectiveness of a distance low GI education intervention, adapted from Diabetes Canada's GI materials, on producing a difference in average dietary GI between a group with the intervention and standard care.
Food Product for Management of Gestational Diabetes
Gestational DiabetesGlucose Tolerance Impaired in Pregnancy3 moreThe goal of this pilot open pre-post clinical trial is to test effects of a wholegrain product in patients with newly diagnosed gestational diabetes. The main question it aims to answer is: Does the wholegrain product improve glucose tolerance and insulin sensitivity during a 75 g oral glucose tolerance test (OGTT). Participants will consume product on two consecutive evenings shortly after the first OGTT and will then perform a second OGTT. Researchers will compare the results of the first and second OGTT to see if glucose tolerance improved after consumption of the test product.

Pre-meal Consumption of Whey in Gestational Diabetes Mellitus From Diagnosis to Delivery
Gestational DiabetesThe main objective of the study is to investigate the metabolic effects of whey protein (whey protein isolate, WPI, (Lacprodan® ISO.Water. from Arla Foods Ingredients) compared with placebo when consumed by women with gestational diabetes mellitus (GDM) from diagnosis (around gestational week 28) to delivery. Any changes in substrate metabolism and energy expenditure using indirect calorimetry will also be investigated. Differences in hunger and satiety parameters as well as blood pressure and gestational weight gain will also be assessed. Furthermore, analysis on the glucose response when the women consume the intervention (whey or placebo) at home in their own environment 30 minutes before breakfast at time of diagnosis (earliest week 28) and week 36 (four days following each time point) will be made. The women will be monitored with continuous glucose monitors, activity monitors and all meals will be provided for two days following the study days in the laboratory. At delivery cord blood will be sampled for analysis on metabolic parameters and investigations on epigenetics/DNA methylations. Complications to the delivery, neonatal outcomes, anthropometrics of the child will also be assessed. Breast milk composition will also be analyzed.
