Active clinical trials for "Hyperglycemia"

Patients with diabetes have an increased risk of sudden cardiac death compared to the general population. Severe hypoglycemia is associated with an increased risk of cardiovascular (CV) disease (CVD) and events, including cardiac arrhythmias and sudden cardiac death; likewise, increased glycemic variability is associated with macrovascular complications and increased mortality. The physiological mechanisms linking hypoglycemia and glycemic variability to CVD and CV events remain unclear. Myocardial work and mechanical dyssynchrony will be measured by speckle tracking echocardiography during euglycemia, hypoglycemia and hyperglycemia in individuals with type 1 diabetes, type 2 diabetes, and without diabetes. Echocardiographic images from three experimental clamp studies - Hypo-Heart 1 (sub-study 1), Hypo-Heart 2 (sub-study 2) and Rapid-Heart - will be included in this study.

In this study, the investigators will test the hypothesis that acute in vivo exposure to hyperglycemia increases mitochondrial network fragmentation and mitochondrial reactive oxygen species production (ROS) production in human arterial endothelial cells.

Normoglycemia is important for the outcome of surgical and medical conditions. Insulin infusions have been studied to achieve normoglycemia during these circumstances and have proved to be useful. Insulin given by subcutaneous injections has longer duration compared to intravenous given insulin which makes it more difficult to control. The hypothesis behind the trial is the concept that insulin infusion is more effective in reaching normoglycemia in diabetic subjects during treatment for ulcer infections and/or planned cardio-vascular surgery. The study evaluates a target controlled insulin infusion or conventional therapy as antidiabetic treatment during ulcer infection and after cardio- vascular surgery. Secondary efficacy parameter will be hospital stay, laboratories for inflammation and oxidative stress.

The primary purpose of this study is to evaluate two glycemic control regimens on clinical outcome in patients with necrotizing soft tissue infections. Secondary aim is to evaluate the inflammatory and immune responses to the glycemic control regimens.

This is a randomized controlled trial to determine the safety and efficacy of Sitagliptin in patients with stress hyperglycemia or mild diabetes following cardiac surgery. Patients will receive Sitagliptin or placebo. Sitagliptin may be of particular use in this patient population due to the effects on hepatic glucose production (a major feature of SH), safety (lack of contra-indications for heart failure or renal failure and no hypoglycemia), and tolerability. The secondary objective of this study is to determine whether the management of patients with persistent insulin requirements following cardiac surgery differs among patients with stress hyperglycemia or mild diabetes.

No consensus guidelines exist for management of post-transplant glucocorticoid induced hyperglycemia, but most published reviews recommend insulin as first line therapy. A variety of insulin regimens have been proposed, including mealtime short-acting regular or analog insulin, once daily neutral protamine hagedorn (NPH) insulin, pre-mixed insulin, or basal insulin alone such as glargine or detemir. However, no randomized trial has ever examined different insulin regimens to determine which most effectively controls post-transplant steroid-induced hyperglycemia. Consequently, the proposed study intends to examine three commonly used insulin regimens used for managing post-transplant once-daily glucocorticoid-induced hyperglycemia to determine which is most effective: Group 1: Intermediate-acting (NPH) insulin at breakfast Group 2: Short-acting insulin (regular or aspart) before meals Group 3: Insulin glargine at breakfast Question/Hypothesis: Among three commonly used insulin regimens, which is most effective for managing post-transplant once-daily glucocorticoid-induced hyperglycemia?

The main aim of the investigation is to clarify, whether vitamin D supplementation in coronary artery disease patients with vitamin D deficiency and postchallenge hyperglycemia has an impact on endothelial dysfunction and parameters of insulin sensitivity and beta-cell function.

The purpose of this study is to determine the effect of preventing hyperglycaemia in patients admitted to hospital with acute exacerbations of chronic pulmonary disease.

To determine whether intensive glucose control results in improved mortality and reduced hospital stay length by performing a randomized trial of intensive glucose management (blood glucose goal 110 mg/dl) using continuous IV insulin and glucose vs. non-intensive glucose management (goal 200 mg/dl)

In response to the evidence supporting "tight" glucose control (70 - 110) in the critical care setting, the MMH ICU developed a protocol utilizing regular intravenous insulin. This protocol was initiated in 2002. Monitoring of the data collected revealed effective glycemic control when this protocol was used. However, limited utilization has led to overall ineffective glycemic control in this ICU. The poor utilization is largely due to a general reluctance of physicians to start their patients on an intravenous insulin infusion. As contributing to this poor compliance is the "open" nature of the ICU. The MMH ICU is an "open" ICU, meaning that many physicians across multiple subspecialties admit to this unit. Approaches to controlling hyperglycemia vary greatly, depending largely upon the treating physician. In an attempt to improve overall glycemic control in this "open" ICU, the Subcutaneaous Insulin Aspart Hyperglycemia Protocol (SIAP) was developed which incorporates a subcutaneous insulin aspart regimen that triggers the use of a regular insulin infusion protocol when the SIAP is not adequately controlling the patient's blood glucose. This study aims to evaluate 1) the effect the SIAP on overall glycemic control in the ICU, 2) the effectiveness that the SIAP has on controlling blood glucose as compared with past practices using regular insulin, and 3) the effect the SIAP has on patient complications and outcomes in the MMH ICU.
