Active clinical trials for "Diabetes Mellitus, Type 1"

The overall objective of this study is to investigate the glycemic response of a 0%, 50%, 100% and 150% bolus insulin correction (based on personal insulin correction factor) of post-exercise hyperglycemia in physically active adults with type 1 diabetes (T1D) using multiple daily injections (MDI) in a controlled, but clinically representative, experimental setting.

The study is going to include 20 adolescents, 5-10 years after onset of T1D, aged 12-20 years, on insulin pump. The participants are going to have MRI of the head in euglycaemic and hyperglycaemic state. During both MRI, the participants are going to preform Flanker test, Tower of London test and Spatial memory test. The investigators are going to evaluate the response of inflammation markers and oxidative stress marekers in blood during hypreglycaemia.

To investigate whether saxagliptin could reduce the fluctuation of glycemia and improve the glycemic control in those type 1 diabetes through mechanisms of suppressing glucagon secretion, improving beta cell function, and re-regulating of the T cell immune system.

The overall objective of this study is to evaluate glycemic control and patient-reported outcomes in patients with Type 1 diabetes (T1D) who use insulin degludec and continuous subcutaneous insulin infusion in a combination untethered regimen during moderate or high-intensity exercise.

The objective is to assess the impact of 12 weeks supplement of sodium-butyrate twice daily or placebo on intestinal inflammation and albuminuria. A randomized, placebo-controlled, double-blind, two-site trial including 48 patients with type 1 diabetes, albuminuria and intestinal inflammation. Participants will be randomized 1:1 to active treatment or placebo for a period of 12 weeks. The primary endpoint is change from baseline to week 12 in intestinal inflammation, measured by fecal calprotectin.

testing of autonomic function and relationship with exercise and Qol in diabetic patients and controls

This study is a single-center, non-randomized, prospective single arm study of adult subjects with type 1 diabetes utilizing 670G insulin pump therapy with Continuous Glucose Monitoring (CGM). These subjects will be using 4 DUO Extended sets that will serve as an exploratory pilot study to assess the 7-day survival of the Duo Extended set.

The aim of this clinical study was to obtain type 1 diabetes data to identify models for glucose prediction and control and to construct a physiological pharmaco-kinetic/pharmaco-dynamic computer model of a type 1 diabetic person.

A couple of studies have shown that illuminating the eye with diffuse flickering light is accompanied by an increase of retinal vessel diameters, optic nerve head blood flow and retinal blood flow. We have recently used this visual stimulation technique as a new and powerful tool for the non-invasive investigation of vascular reactivity. Additionally, we could show that this response is diminished in patients with vascular pathologies and that the response is dependent on nitric oxide, indicating that flicker induced vasodilatation may reflect endothelial dysfunction and may be a new approach to test endothelial function in vivo. One of the most widely used method for the assessment of endothelial function is flow mediated dilatation (FMD). FMD has been shown to give a reliable estimate of vascular function in vivo. In the present study, we set out to compare the standard method for the evaluation of endothelial function, FMD, to flicker induced vasodilatation in the retina.

This study will be conducted in subjects with Type 1 diabetes mellitus on multiple daily insulin injections to determine the correct insulin dosing formulas. Subjects will be evaluated using continuous glucose monitoring.
