Active clinical trials for "Hypoglycemia"

The purpose of this study is to evaluate the usefulness of plasma 1,5-anhydro-D-glucitol (1,5-AG) as a novel surrogate marker of hypoglycemia

This project will study whether infants with Prader-Willi Syndrome experience low blood sugars after short periods of fasting. This study will also evaluate metabolic markers in the blood to determine if infants with Prader-Willi Syndrome process energy differently than other children during fasting.

The purpose of this study is to assess whether the current recommendation for a 50% dose reduction in insulin for diabetic patients with a creatinine clearance (CrCl) ≤15 mL/min or on hemodialysis results in an increased number of hypoglycemic episodes.

This study will assess the correlation between glycemic control and the hypoglycemia symptom score in patients with Type 2 diabetes, 12 weeks after addition of a sulfonylurea to an ongoing regime of oral hypoglycemic agents.

Hypoglycemia occurs frequently during intensive blood glucose control in critically ill patients. The incidence of hypoglycaemia is associated with impaired outcome. However, it is hitherto unknown if hypoglycaemia itself predisposes patients to neurological impairment, e.g. cognitive dysfunction, or if it is the underlying medical condition that makes the patient prone to a high risk of hypoglycaemia and, concomitantly, neurocognitive impairment. Therefore we investigate neurocognitive function in patients who had hypoglycemias during their intensive care stay and compare the results to patients without hypoglycaemia whose medical conditions are matched to the hypoglycaemia patients.

125 children with Type 1 Diabetes mellitis (T1DM) between 4 and 16 were recruited and 62 healthy siblings also enrolled in the study. Children with T1DM and sibling controls ages 4 to 16 were assessed on memory and executive control skills at entry to the study (Test 1) and after two years of close monitoring for blood sugar events (Test 2). Diabetic children have their blood sugar tested directly before and after cognitive testing to ensure their blood sugar is within range during the testing. The 2-year follow-up period involves parents/child reporting any severe diabetic episode and periodically providing the results of the diabetic child's usual blood tests from their glucose monitoring device. Children 7 and older also underwent high resolution MRI scans.

Hypothesis: Low blood sugar (hypoglycemia) decreases function of the lining of the blood vessels in normal humans. This study is designed to explore how hypoglycemia affects the function of the blood vessel lining. This will be determined by measuring blood flow to the arm before and after occlusion of flow. Blood vessel function will be measured before induction of hypoglycemia, during insulin induced hypoglycemia, and after recovery from hypoglycemia. A second study will be done but without hypoglycemia.

This will be a single centre study at the Prince of Wales Hospital, Hong Kong. Patients will be identified from an existing registry of diabetes patients with CKD. Potential subjects will be identified from patients attending diabetes, general medical and renal clinics. Following informed consent, patients will undergo screening where baseline HbA1c, renal function will be measured along withcomprehensive medical and drug history to confirm eligibility. All eligible patients will be fitted with a blinded CGM (Medtronic iPro2 professional CGM) on week-1 for baseline glucose profiles for capturing baseline CGM profile. In case of blinded CGM sensor loss or malfunction, the sensor will be replaced once. Patients with at least 50% sensor data during the blinded wear period will proceed to randomization. At week 0, patients will be randomized to the flash glucose monitoring or SMBG. Both groups will receive standardised education on diabetes self-management, prevention and treatment of hypoglycaemia. This will be accordance with the usual practice at the study site. In the FGM group, patients will receive training on insertion, operation of the device with access to the device software for viewing of ambulatory glucose profiles. Patients will be advised to confirm blood glucose readings with SMBG in the event of hypoglycaemic symptoms, if FGM displays glucose <3.9mmol or in event of glucose instability. Patients randomized to the control group will perform SMBG using dedicated blood glucose meter at least twice daily. Blinded CGM will again be worn in both groups at week 16 for assessment of primary and secondary outcomes. Subjects will compete a hypoglycaemia diary for documenting symptomatic or asymptomatic hypoglycaemia during the study period. Questionnaires on hypoglycaemia unawarenesss, fear of hypoglycaemia and patient-reported outcomes will be completed at baseline, week 8 and week 16 in both groups.

Intense exercise is a major challenge to the management of type 1 diabetes. The management is even more difficult, during a camp, probably due to increased hypoglycemia maybe from increase of intensity of physical activity. The investigators want to evaluate steps, energy expenditure, sleep time and glycemic control and insulin dosage, through use of a wrist accelerometer, in pediatric type 1 patients attending a camp. Finding a correlation between these parameters could be useful not only for educational purposes but also in the development of algorithms for artificial pancreas.

Uncontrolled diabetes is associated with increased risk for micro-vascular complication. Hypoglycemia is one of the major barriers in achieving good glucose control. Hypoglycemia is associated with a range of unpleasant symptoms including palpitations, tremor, hunger, sweating, confusion, difficulties in thinking as well as other idiosyncratic symptoms. Fear of hypoglycemia (FOH) refers to phobic avoidance reactions associated with hypoglycemia FOH may increase behavioral attempts to avoid hypoglycemia including decreased consumption of insulin and/or increased consumption of carbohydrates, resulting in poor glycemic control and an increased risk of diabetic complication. In this study, the investigators present a novel system, which simultaneously employs BioFeedback and Virtual Reality in order to cope with fear of hypoglycemia.
