Diabetes Paid Clinical Trials in Iowa

Women with a history of gestational diabetes mellitus (GDM) are at a 2-fold greater risk for the development of overt cardiovascular disease (CVD) following the effected pregnancy. While subsequent development of type II diabetes elevates this risk, prior GDM is an independent risk factor for CVD morbidity, particularly, within the first decade postpartum. GDM is associated with impaired endothelial function during pregnancy and decrements in macro- and microvascular function persist postpartum, despite the remission of insulin resistance following delivery. Collectively, while the association between GDM and elevated lifetime CVD risk is clear, and available evidence demonstrates a link between GDM and vascular dysfunction in the decade following pregnancy, the mechanisms mediating this persistent dysfunction remain unexamined. The purpose of this investigation is to examine the role of endothelin-1, a potent vasoconstrictor, in aberrant microvascular function in otherwise healthy women with a history of GDM and to identify whether this mechanism is influenced by physical activity and sedentary behavior.

The goal of this clinical trial is to investigate whether metformin improves vascular function in individuals with prediabetes. The main questions it aims to answer are: 1. Does metformin improve large conduit artery endothelial function in individuals with prediabetes? 2. Does metformin improve microvascular endothelial function in individuals with prediabetes? Researchers will compare metformin to a placebo to see if metformin improves vascular function in prediabetes. The trial duration is 12 weeks. Participants will take metformin or a placebo once a day for 2 weeks. After 2 weeks, participants will take metformin or a placebo twice a day for the remaining 10 weeks. There will be a screening visit, two baseline visits, a 4-week safety visit, and two 12-week end-of-study visits. Adherence will be calculated from pill count and adverse events will be quantified via a questionnaire. Read Less

The purpose of this study is to assess the safety and efficacy (including durability) of up to 2 REACT injections given 3 months (+30 days) apart and delivered percutaneously into biopsied and non-biopsied contralateral kidneys in participants with T2DM and CKD. Read Less

This is a multi-center, prospective, non-interventional study that focuses on the long- term effects following participation in selected ITN new-onset Type1 Diabetes Mellitus studies with immunomodulatory agents (T1DM, T1D). This observational study will: * follow participants to determine how long they continue to produce insulin, and * will also assess how changes in the immune system over time relate to the ability to produce insulin. This information could help design better therapies for type 1 diabetes in the future. 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

Kidney transplantation improves the health and quality of life for those Veterans with end stage kidney disease (ESKD). While early patient and graft survival are excellent, long-term outcomes continue to be challenging. Patient death with existing kidney graft function occurs in about half of all recipients over time. This is primarily due to the development of cardiovascular disease in a patient population with multiple preexisting cardiac disease risk factors. There has been little progress in improving outcomes in this area for over two decades. Recent studies in chronic kidney disease (CKD) patients using SGLT2 inhibitors (SGLT2i), regardless of the presence of type 2 diabetes mellitus (T2DM), results in both kidney protective and cardiac protective impacts and improved patient outcomes. However, kidney transplant recipients (KTRs) were excluded from these clinical trials due to concerns that these agents promote infection, diminish graft function, and may alter immunosuppressive drug levels that are the mainstay of patient's transplant therapy. There are limited published data of SGLT2i treatment of selected KTRs. Read Less

This study will examine whether continuous glucose monitoring in patients hospitalized in the immediate postpartum period is more effective than traditional point of care glucose testing in identifying patients with hypoglycemia. Read Less
