Study of High Blood Sugars and Insulin in Hospitalized, Critically Ill Children
Critical IllnessHyperglycemiaBACKGROUND AND PURPOSE Critical illness hyperglycemia (CIH) - elevated blood glucose in the critically ill patient population - has gained much interest among health care providers over the past several years. Clinical studies in adults have documented a high rate of hyperglycemia in some post-surgical and medical intensive care units (ICUs). However, the primary reasons for interest in this topic are not due just to its high rate, but also to the fact that by returning the high glucose levels found in this population to normal with insulin therapy can dramatically improve clinical outcomes by decreasing both morbidity and long-term mortality. Because of this, aggressive glucose control has become common practice in adult ICU critical care management. Although there is substantial data describing the high incidence of CIH in adult patients, there is little information regarding this condition in children. A single retrospective study recently published also suggested a high incidence of CIH in children with critical illness secondary to both medical and surgical causes. It is yet to be determined if, like in adults, normalizing blood glucose levels with insulin improves outcomes in this pediatric population. Because evidence appears compelling that hyperglycemia is both common and detrimental in adults, many pediatric ICUs have likewise begun to focus on aggressively treating hyperglycemia in critically ill children. The proposed study is a prospective observational pilot study to occur in the Pediatric Intensive Care Unit (PICU) at Children's Healthcare of Atlanta at Egleston. This prospective pilot study is being done to evaluate the endocrine factors associated with, if not responsible for, CIH, and the changes that take place with the restoration of normal blood glucose levels by insulin therapy. To address these profound issues this study will pursue two interrelated Aims: Aim #1: To determine if critical illness hyperglycemia is associated with absolute insulin deficiency, peripheral insulin resistance, or both. Aim #2: To characterize the requirement of insulin required to initially restore and maintain normal blood glucose levels, and compare the changes in insulin that take place with this normalization in patients with CIH. We hypothesize that the hyperglycemic response to critical illness will be associated with abnormally low levels of insulin as compared to patients without critical illness hyperglycemia.
The Effect of Late Night Meals on Fasting Glucose in Type 2 Diabetes Patients
Fasting HyperglycemiaHigh fasting glucose is a very common problem in type 2 diabetic patients. The cause is probably glucose production by the liver, known as the "dawn phenomenon". The investigators hypothesize that a late night meal can lower the fasting glucose level by early morning insulin secretion stimulated by the food. In this study the investigators intend to test the effect of different kinds of late night meals on fasting glucose in type 2 diabetic patients.
GLP 1 for Intraoperative Glycemic Control

Bone Marrow as an Alternative Site for Islet Transplantation
Type 1 DiabetesPostpancreatectomy HyperglycemiaThe goal of this study is to evaluate safety and feasibility of bone marrow (BM) as site for islet transplantation (Tx) in humans. The investigators hypothesis is that BM represents a better site than liver thanks to its potential capacity to favor islet engraftment in face of a more easiness of access and bioptic follow up.
The Effect of a Low Glycemic Index Diet on Blood Sugar Control in Women With Gestational Hyperglycemia...
Gestational DiabetesThe purpose of the study is to see if a low glycemic index diet will reduce blood sugar levels in pregnant women with high blood sugar levels.
A 56-Week Extension to a Clinical Study to Assess the Efficacy and Safety of Vildagliptin Compared...
Diabetes MellitusType 2This study is not being conducted in the United States. Key long-term clinical studies have shown that people with type 2 diabetes should try to achieve overall blood glucose levels as close to normal as possible. The purpose of this study is to gather data on the long-term safety and effectiveness of vildagliptin, an unapproved drug, compared to placebo in lowering overall blood glucose levels in people with type 2 diabetes who have not been previously treated with drug therapy to lower their blood sugar and whose blood glucose levels are close to normal.
Computerized Glucose Control in Critically Ill Patients
HyperglycemiaCritical IllnessThe aim of the study is to determine whether the use of the CGAOtm software is associated with a decrease in 90-day mortality when compared with the use of standard care methods for glucose control with target blood glucose levels inferior to 180 mg/dl. The CGAOtm software is designed to assist physicians and nurses in achieving tight glucose control (defined by a target for blood glucose levels between 80 and 110 mg/dl) in critically ill patients.
Home Versus Hospital Care in Glucose Monitoring of Gestational Diabetes and Mild Gestational Hyperglycemia...
Gestational Diabetes MellitusPregestational Diabetes Mellitus1 morePregnancies complicated by diabetes and mild gestational hyperglycemia are associated with increased perinatal and maternal complications. The most serious maternal complication is the risk of developing type 2 diabetes after 10-12 years of the delivery. Perinatal complications include fetal macrosomia with consequent increased risk of obstetrical trauma and hypoxia/asphyxia, high rates of cesarean section, respiratory distress syndrome, and metabolic disorders at birth. Regardless of the diagnosis of diabetes and mild gestational hyperglycemia, the perinatal outcome is directly related to maternal metabolic control. For the tight control of blood glucose, pregnant women are treated as home care (outpatient) or hospital care. Objective: To evaluate the cost-effectiveness and safety of home versus hospital care of gestational diabetes and mild gestational hyperglycemia.
