Active clinical trials for "Hyperglycemia"

The purpose of this prospective study is to determine if trial use of a Dexcom G6 CGM system for a 10 day wear period in pediatric Type 2 diabetes patients improves short term time in range glucose control and 3-6 month glycemic control.

The clinical relevance of the observed stress induced hyperglycemia in trauma patients remains unclear. The earlier studies suggested the implications of cytokines in stress induced hyperglycemia and the outcomes after trauma. To date, there is little information available regarding the effect of diabetic hyperglycemia (occult or known) on outcomes after trauma and whether these patients represent a distinct group with differential outcomes when compared to those with stress-induced hyperglycemia. Herein, the purpose of this study is to identify the incidence of stress induced hyperglycemia as well as diabetic hyperglycemia in trauma patients and to investigate the association between proinflammatory cytokine levels and hyperglycemia in our trauma population.

This study was a partly controlled laboratory-based study comparing the glycemic and insulinemic indices of 3 test meals containing soft drink alone or with SUGARDOWN™ (Galactomannan) in overweight adults.

Orange juice naturally contains high concentrations of hesperidin, which affects glucose absorption in in vitro experiments. This study is to test if hesperidin and other components of orange juice (not other sugars or organic acids) affect the post-prandial blood glucose concentration derived from sugars already present in the orange juice.

Intensive care unit (ICU) patients commonly display hyperglycemia, even without previously known diabetes. It was demonstrated that hyperglycemia was associated with increased hospital mortality in various medical and surgical ICU situations. However, discrepant results from recent randomized, clinical trials of tight blood glucose control in ICUs have not allowed conclusions regarding whether there is a causal link between hyperglycemia and ICU mortality. In addition to the mean blood glucose level, glucose variability has recently been emphasized as an independent predictor of ICU and hospital mortality. This concept has been described in a wide variety of medical, surgical and trauma ICU patients. In all of these settings, glycemic variability was measured with various indices but was steadily associated with ICU and/or hospital mortality in non-diabetic ICU patients. Conversely, glycemic variability was either weakly or not associated with mortality in ICU patients with previously known diabetes. Notably, all of these data have been observational, and interventional trials remain lacking to assess the impact of glycemic variability reduction on ICU mortality and thus to demonstrate causality. However, glycemic variability was considered sufficiently important to be mentioned in recent international guidelines for the management of hyperglycemia in critically ill patients. In these publications, experts from the American College of Critical Care Medicine emphasized that glycemia should be maintained at less than 9.9 mmol/L in ICU patients while avoiding hypoglycemia and minimizing glycemic variability. To achieve these goals, computer-based insulin infusion protocols have demonstrated their superiority to paper-based protocols. Glucose concentrations, variation per unit of time between the last and current glucose measurements, insulin dosage, and carbohydrate intake were the main input variables used in these different computerized algorithms. However, such protocols are not widely available because commercial systems have licensing fees and academic protocols do not always go beyond the pilot phase. To address this issue, the investigators adapted a previously validated, paper-based, dynamic protocol (DP) to an actual recommended glycemic target range. Our aim was to assess the efficacy, safety, feasibility and acceptance by nurses of this dynamic insulin protocol, compared to a paper-based, sliding scale static protocol (SP).

The purpose of this study is to assess safety and device performance of the Medtronic Hospital Glucose Management System (HGMS) for up to 72-hours.

To determine whether intraoperative hyperglycemia potentiates renal injury in the setting of cardiac surgery requiring cardiopulmonary bypass.

Hyperglycemia is frequent manifestations of the human metabolic response to systemic inflammatory response syndrome (SIRS),sepsis and septic shock, and are implicated in the clinical outcome. Adrenomedullin is elevated in SIRS, sepsis and septic shock and has been demonstrated the inhibitory role on insulin and adrenocorticotropic hormone secretion. Our hypothesis is that: AM elevation after SIRS could be the responsible to maintain hyperglycemia

The overall goal of this proposal is to determine the effects of acute hyperglycemia and its modulation by Glucagon-like Peptide-1 (GLP-1) on myocardial perfusion in type 2 diabetes (DM). This study plan utilizes myocardial contrast echocardiography (MCE) to explore a) the effects of acute hyperglycemia on myocardial perfusion and coronary flow reserve in individuals with and without DM; and b) the effects of GLP-1 on myocardial perfusion and coronary flow reserve during euglycemia and hyperglycemia in DM. The investigators will recruit individuals with and without DM matched for age, gender and degree of obesity. The investigators will measure myocardial perfusion at rest and during vasodilator stress (to ascertain coronary flow reserve) while subjects are under controlled pancreatic clamp conditions during euglycemia (glucose ~100 mg/dl) and hyperglycemia (glucose ~250 mg/dl) in the presence and absence of concomitant GLP-1 infusion. The investigators believe that the translational significance of their studies is immense, impacting upon both acute and chronic cardiovascular disease manifestations. The effect of glycemic control on cardiovascular outcomes, morbidity and mortality remains an area of active investigation, fueled by the recent conflicting results of several large clinical trials (ACCORD, United Kingdom Prospective Diabetes Study (UKPDS), ADVANCE, VADT). If the investigators find that hyperglycemia is associated with altered myocardial perfusion, the mechanistic implications in the prevention and management of acute and chronic cardiovascular diseases in DM will be groundbreaking. Furthermore, if GLP-1 augments myocardial perfusion (as it does in the peripheral vasculature), the therapeutic benefits for prevention of cardiovascular events in this predisposed population are clear.

A blood glucose level of equal to or greater than 180 mg/dL that occurred during stress in a patient without diabetes mellitus (DM) is termed stress hyperglycemia (SH). The stress hyperglycemia ratio (SHR) is defined as the fasting blood glucose divided by the blood glucose level that is calculated from the glycosylated hemoglobin (HBA1c) value on admission. A significantly higher SHR is associated with worse prognostic biomarkers in diabetic patients with complications
