Gestational Diabetes Clinical Trials

The objective of this study is to compare the accuracy of a 2hr glucose tolerance test administered during the postpartum hospitalization with the standard of care glucose tolerance testing (administered at 6 weeks postpartum). The primary hypothesis is that the glucose tolerance test administered in the postpartum period will be accurate and will improve compliance with postpartum testing for gestational diabetics.

The overarching research question is: "Does the provision of healthy food (Delivering HOPE) during pregnancy reduce the proportion of women who experience excessive gestational weight gain compared with enhanced standard of care (ESoC)?" To answer this question, the investigators will conduct a large multi-site randomized controlled trial with 1,440 women. Women will be randomized to either the Delivering HOPE arm or the ESoC arm, with approximately 720 participants per arm. Participants randomized to the ESoC arm will receive the standard clinical protocol for nutritional and gestational weight gain counseling recommended for all pregnant women, WIC and SNAP enrollment assistance, referrals to safety net food organizations.Those randomized to the Delivering HOPE arm will be provided the same nutritional and gestational weight gain counseling, WIC and SNAP assistance, and food referrals, as well as a total of $1000/$2000/$3000 (depending on household size) during pregnancy to be used specifically for the purchase of healthy foods recommended in the nutritional counseling. Data for the primary outcome (pre-pregnancy weight and weight at delivery) will be collected from birth records. Read Less

The purpose of the research study is to better understand how beta-cells (cells in the pancreas that make insulin and help regulate blood sugar) respond to growth hormone in people with a personal history of gestational diabetes (high blood sugar in pregnancy) at the University of Missouri. The aim of the study is to advance understanding of how growth hormone affects beta-cells and risk factors for developing gestational diabetes and type 2 diabetes. Read Less

The purpose of this study is to assess whether an AI based counseling service can be beneficial for patients to assist in management of gestational diabetes. Read Less

The purpose of this investigation is to examine NADPH oxidase as a source of reactive oxygen species contributing to aberrant microvascular function in otherwise healthy women with a history of GDM. Read Less

The purpose of this investigation is to examine the mechanisms mediating vascular dysfunction in women who have had gestational diabetes and how metformin may be a valuable treatment tool to improve microvascular function in these women before the onset of disease. Read Less

The purpose of this investigation is to examine the role of oxidative stress in aberrant microvascular function in otherwise healthy women with a history of GDM. Read Less

One third of women with gestational diabetes (GDM), diabetes diagnosed during pregnancy, have abnormal glucose levels within 3 years after pregnancy, but follow up is low. Continuous glucose monitors (CGM), a small sensor inserted under the skin, may be able to screen women with GDM for diabetes risk. The investigators will ask postpartum women to use CGM at 6-8 weeks postpartum and answer surveys about quality of life after wearing the CGM. The investigators will collect data on blood glucose trends for future studies if participants find CGM use acceptable. The investigators hope to learn if CGM could improve postpartum follow up experiences for people with recent GDM. Read Less

Healthy for Two, Healthy for You (H42/H4U) is an innovative evidence-based pregnancy/postpartum health coach intervention that is remotely-delivered (phone coaching using motivational interviewing, web-based platform, mobile phone behavioral tracking). The aim of this randomized controlled trial (RCT) is to embed H42/H4U into Johns Hopkins prenatal care clinics that serve a racially and economically diverse population, leveraging existing staff as trained health coaches to test its effectiveness and implementation. The investigators hypothesize that women in the H42/H4U arm will have lower gestational weight gain and lower rates of gestational diabetes, without an increase in low birth weight infants, and that implementation into the investigators' prenatal care clinics will be feasible and scalable.

This study's primary purpose is to determine the relationship between aspirin metabolism and markers of metabolic dysfunction among patients at risk for preeclampsia. Further, we will add an exploratory outcome to evaluate the neonatal body composition and anthropometric data to better understand neonatal impacts of maternal metabolic dysfunction. Read Less

This will be a randomized trial of patients with gestational diabetes who start hypoglycemic therapy with metformin but eventually require insulin. It will examine whether continuing metformin when adding insulin versus discontinuing metformin when insulin is added is beneficial. The investigators hypothesize that continuing metformin will reduce the needed insulin dosage and improve maternal and neonatal outcomes in these patients. Read Less

This study is being done to study how exenatide, an FDA-approved drug that lowers blood sugar in non-pregnant patients with type II diabetes, works in pregnant women. To do this, the investigators will study the drug's pharmacokinetics (what the body does to the drug; specifically, how quickly your body breaks down and excretes exenatide) and pharmacodynamics (what the drug does to the body; specifically, how effectively exenatide helps the participants' pancreas secrete insulin and how well it controls blood sugar after a meal). There are only two main drug therapies (insulin injections and glyburide pills) currently used for gestational diabetes and not all women achieve good enough blood sugar control without side effects. Therefore, the investigators hope to find out if exenatide might also be helpful in gestational diabetes. Read Less
