Active clinical trials for "Diabetes, Gestational"

Pregnant women with gestational or Type 2 diabetes who require medication are placed in one of two groups: Insulin injections or Glucovance (oral administration). Blood glucose is checked 5 times per day, and medication adjusted by perinatologist according to glucose levels. The hypothesis is that patients will have similar or improved blood glucose control on an oral agent as compared to control on insulin.

The association of hyperglycaemia in pregnancy (gestational diabetes mellitus; GDM) with adverse maternal and fetal outcomes is clearly recognised. Traditionally the diagnosis is made at 28 weeks gestation at which stage children of affected women already have a two-fold rate of excessive weight gain (abdominal circumference > 90th percentile). This is attributed to fetal exposure to undiagnosed high blood glucose earlier in pregnancy. Indeed almost 25% of women with GDM develop the condition before 20 weeks gestation. Interventional studies in women diagnosed in the late second trimester have shown benefits in reducing fetal macrosomia. It is unknown whether screening in the first trimester would predict fetal macrosomia and allow more timely and effective intervention. To examine this question, we propose a prospective cohort study of 1,662 women at increased risk of GDM to determine if an elevated HbA1c (39-48mmool/l) in early pregnancy (<14 weeks) can identify babies at risk of excessive weight gain in later pregnancy, as determined by ultrasound measurement of abdominal circumference at 28 weeks gestation. The study will be largely integrated into routine clinical practice enabling a large number of women to participate. Study participants will all undergo formal screening (75g oral glucose tolerance test) for GDM at 28 weeks gestation. Secondary outcomes, namely the ability of early pregnancy HbA1c to predict later maternal GDM, and fetal and maternal complications of pregnancy will also be evaluated. The results of this study, if positive, are likely to impact upon patient care almost immediately following study completion. In addition, given the stability of the Northern Ireland population, the relatively unique data set will facilitate future work on predictive markers for cardiovascular disease, and prospective studies on the cardiovascular consequences of GDM on both mother and baby.

This study aims to investigate whether high-morning carbohydrate intake (HMK) compared with low-morning carbohydrate intake (LMK) affects glycemic variability in GDM patients based on Continuous glucose monitoring (CGM). High carbohydrate morning intake is expected to reduce hyperglycemic episodes and stabilize blood glucose compared with low morning carbohydrate intake.

The purpose of this study is to verify if postprandial walks are effective in obese pregnant women, as regards to gestational weight gain and typical diseases of that period, as gestational diabetes and preeclampsia. Perinatal outcomes will be observed, such as macrosomia, shoulder dystocia and fetal death.

The thought is that Non-Alcoholic Fatty Liver Disease (NAFLD) plays a key role in the progression to prediabetes/T2DM in those with a history of Gestational Diabetes (GDM). The investigators want to know if having a fatty liver will be connected with more glucose abnormalities (higher fasting/oral glucose tolerance test glucose, more insulin resistance) and that a history of GDM will be common in those with NAFLD.

Since the prevalence of gestational diabetes melitus (GDM) increased by ..., as an important part of medical treatment, nutrition therapy is highly required to help patients achieve normoglycemia. Carbohydrate intake is the primary nutrient affecting postprandial glucose levels,therefore the total amount and type of carbohydrate should be manipulated to blunt postprandial hyperglycemia. However,the type of carbohydrate has not yet been established. Rice and wheaten food have similar Glycemic Index (GI),but some researches found the glucose response to them is different. A case-control study is designed to compare the glucose control status between rice-richen meal and wheaten-richen meal, and all other macronutrients and micronutrients are all calculated and same between two groups, which may provide more clues for type of carbohydrate recommendation for Chinese women with GDM.

Gestational diabetes (GDM) is a condition of carbohydrate intolerance with onset or first recognition in pregnancy. The prevalence of GDM is as high as 25% in some populations and continues to rise with the increase in obesity and type-2 diabetes. GDM places the pregnancy at great risk to both the mother and the neonate. Recent studies have proven that interventions including dietary and medications lower the risk to the pregnancy. Both the American College of Obstetrics and Gynecology (ACOG) and the American Diabetes Association (ADA) recommend dietary interventions with daily glucose monitoring as the initial treatment of choice. Meanwhile, outside of pregnancy, promising new technologies such as continuous glucose monitors (CGM) are revolutionizing diabetic care. The investigators seek to determine if the constant feedback of a real-time CGM system would improve glycemic control compared to traditional management in GDM

Background: Gestational diabetes mellitus (GDM), GDM is the first time of gestational impaired glucose tolerance in pregnant women. It is the most common complication disease in women of childbearing age. It is associated with the high risk of adverse health outcomes for both mothers and offsprings and the variety of metabolic disease, including type 2 diabetes, etc. As for the epidemiology data of GDM in China, the prevalence is around 18% based on the criteria from the International Association of Diabetes in Pregnancy Study Groups, IADPSG. Several studies claimed that the diabetes-specific formula improved glycemic control in type 2 diabetes patients. However, the effects of medical nutrition therapy combined with the diabetes-specific formula in pregnant women with gestational diabetes mellitus (GDM) are unclear. Objective: This study examines whether medical nutrition therapy combined with Enteral Nutrition Suspension (TFP-DM, Diason 0.75 kcal/ml) in GDM women could improve the glycemic control and the pregnancy outcomes.

Gestational diabetes (GDM) represents a significant and growing source nationwide of morbidity and mortality for both mothers and infants. Between 5 and 10% of pregnancies are complicated by GDM. Infants exposed in utero to hyperglycemia from GDM have an increased risk of neonatal complications as well as an increased prevalence of a number of chronic diseases, including type 2 diabetes and schizophrenia. Recent research shows that treatment with metformin begun as soon as hyperglycemia is detected in pregnancy is safe and effective. Additional studies demonstrated that metformin is able to decrease the incidence of type 2 diabetes among individuals at risk for this disease. Based upon these findings, the investigators propose to test the hypothesis that metformin therapy for women at risk for gestational diabetes, started prior to conception and before the onset of hyperglycemia, both decreases the incidence of and improves the maternal and neonatal outcomes from GDM. The investigators intend to conduct a prospective, randomized, double-blind placebo controlled range-finding study to measure the effects of early metabolic intervention with metformin in women at risk for GDM before the commencement of pregnancy or prior to completion of the first trimester. The target sample size for this pilot study is 100 women. The effect size observed will provide preliminary data for a subsequent study which will be sufficiently powered to detect small or moderate effects from early metabolic intervention in women at risk for GDM. The specific aims of the proposed research consist of the following: Determine whether treating women at risk for GDM with metformin prior to conception and/or completion of the 1st trimester decreases the incidence of GDM at 26 weeks' gestation. Evaluate the effects on maternal and fetal pregnancy outcomes of pre-conception metabolic intervention with metformin in women at risk for GDM. Use these pilot study results to: identify specific demographic characteristics associated with an intervention effect calculate effect size for specific outcomes provide range-finding data for a subsequent study design Metformin therapy for women at risk for gestational diabetes, started prior to conception and before the onset of hyperglycemia, both decreases the incidence of and improves the maternal and neonatal outcomes from GDM.

The purpose of this study is to determine whether metformin is effective and safe in the treatment of diabetes in pregnancy.
