Active clinical trials for "Hypoglycemia"

You are invited to participate in a study designed to investigate the effects of diabetes mellitus, high and low glucose, and high blood insulin on the brain. You were selected as a possible participant because you fit into one of the following categories. a) you are either healthy and competent, are not pregnant and you have no known medical disease and therefore your glucose metabolism will be typical of a normal person, or b) you have diabetes.

No studies have investigated if the dietary composition of carbohydrate influences the glycaemic effect of single and multiple boluses of subcutaneous low-dose glucagon. Further, the recommended diet composition to patients with type 1 diabetes has not been thoroughly validated. Many patients with type 1 diabetes practice low carbohydrate eating patterns due to the assumption that this diet can reduce fluctuations in plasma glucose. Before glucagon can be used as an add-on to intensive insulin treatment, these aspects need to be elucidated. The purpose of this study is to determine, whether diet composition of carbohydrate affects the glycogen stores in the liver and affects the glucose response of glucagon during hypoglycaemia. HYPOTHESIS: In patients with type 1 diabetes, the glucose response of a single bolus of low-dose glucagon is not associated with diet carbohydrate content. AIM: The aim is to investigate how one week of high- compared to low-carbohydrate diet influence the glycaemic response of low-dose glucagon in patients with insulin pump treated type 1 diabetes. The secondary aim is to investigate how two dietary intervention weeks differ in the incidence of hypoglycaemia, postprandial hyperglycaemia, and daily glucose excursions. DESIGN:A non-blinded two-way cross-over, randomized study will be conducted. After participants have given an informed consent, they will go through four steps: 1) screening visit 2) Run-in period, 3) first meal intervention for one week finalizing with one study visit and 4) second meal intervention for one week finalizing with another study visit.

Neonatal hypoglycemia is associated with brain injury and impaired neurodevelopment outcomes in very low birth weight infants (VLBWI). Glycemic monitoring is usually performed by capillary or central line sampling but does not identify up to 81% of hypoglycemic episodes in preterm newborns. The investigators aim to assess if a continuous glucose monitor (CGM) can be used to maintain euglycemia (defined as a target value 72-144mg/dl) in VLBWI. It will be enrolled newborns ≤32 weeks gestational age and/or of birthweight ≤1500 g, within 48 hours of life, they will be randomized in two study arms, both them will wear Dexcom G4 Platinum CGM: 1) Unblinded group (UB): glucose daily intake will be modulated according to CGM (Dexcom G4 Platinum) during the first 7 days of life, alarms for hypos/hyper will be active; 2) Blinded group (B), glucose infusion rate will be modified according to 2-3 daily capillary glucose tests, alarms for hypos will be switched off. Pain at insertion will be evaluated with the validated Premature Infant Pain Profile (PIPP) scale. The estimated numerosity is 50 patients (25 for each arm).

Glucose is a sugar carried in the blood stream that body uses for energy. If someone has diabetes, blood glucose level can be erratic, sometimes becoming very low this is called Hypoglycaemia (or a "hypo"), and can happen when blood glucose levels drop below 4 mmol/l. So far in order to prove that a hypo happened for a patient, blood glucose level can only be measured at time of the hypo and not after it. In this study we are trying to identify certain chemical substances (biomarkers) in diabetic patients that may be measured in blood tests of the patient up to after 24 hours of the hypo and if we could prove that a hypo has happened we could adjust tablets and or insulin dosage in a way to prevent further hypos. The study will be conducted in the Diabetes Centre in Hull Royal Infirmary and will involve three visits to the diabetes centre. The study can finish in a week time after the first visit. Visit 1 is the screening visit to identify eligibility to take part in the study. Visit 2 insulin infusion will be given to make participants blood sugar level fall lower than normal for a short time and corrected quickly afterward. This is a stress for participant's body and should stimulate certain chemicals that we are trying to identify during hypo. In Visit 3, the main purpose of this visit which is done 24 hours after insulin infusion is to take a blood sample and check how participants is after visit 2. We will recruit 25 Type 2 Diabetic patients and 25 none diabetics to compare both results. Both groups should not have ischemic heart disease, underactive thyroid or seizures and on stable dosage of medications.

The Brigham and Women's Hospital (BWH) Patient Safety Learning Laboratory (PSLL) focuses on developing health information technology (HIT) tools to engage patients, family, and professional care team members in reliable identification, assessment, and reduction of patient safety threats in real-time, before they manifest in actual harm.

Patients with type 1 diabetes (T1DM) who are unable to perceive symptoms of hypoglycemia, referred to as impaired awareness of hypoglycemia (IAH), are at very high risk of severe hypoglycemia. IAH affects approximately 25% of patients with T1DM. Brain lactate may be involved in the development of IAH. A recent study indicated increased brain lactate utilization during hypoglycemia in T1DM patients with IAH, which did not occur in patients with normal awareness of hypoglycemia (NAH). Conversely, administration of lactate to patients with NAH has been shown to attenuate counterregulatory hormone responses to and symptomatic awareness of hypoglycemia, thus causing a situation that resembles IAH. It has, however, not been demonstrated whether the excess of lactate is actually taken up or metabolized by the brain, and if so whether this occurs under euglycemic or hypoglycemic conditions or both. This project consists of two related studies. The objective of part 1 is to investigate the effect of elevated plasma lactate levels that are sufficient to impair awareness of hypoglycemia on brain lactate concentrations during euglycemia and hypoglycemia in T1DM patients with NAH. The objective of part 2 is to compare the effect of exogenous lactate on brain lactate concentrations between T1DM patients with NAH and T1DM patients with IAH. Furthermore, this study aims to determine the effect of acute hypoglycemia on the inflammatory function and composition of peripheral blood mononuclear cells.

This study will look at two FDA approved medications that improve how the pancreas works in patients with Type 2 Diabetes. In order to understand how these medications work in patients with diabetes we must first measure the normal response in healthy volunteers without diabetes. We will be looking at the body's normal physiological response to low blood sugar and whether this will be modified by these medicationsThe hypothesis would be that glimepiride induced insulin secretion will be inhibited by hypoglycemia.

Postprandial hyperinsulinaemic hypoglycaemia is an increasingly recognized adverse side effect of bariatric surgery. Affected individuals experience low glucose levels 1-3 hours after intake of meals, accompanied by symptoms such as drowsiness, sweating, hunger and palpitations. Hypoglycaemia can be serious and have potential dangerous health impact (e.g. road accident or fall due to loss of consciousness). The pathophysiology is incompletely understood and more research is needed in search of preventive and therapeutic strategies.

The primary objective of this study is to assess the effect of the natural course of postprandial hypoglycemia vs. a postprandial euglycaemic condition on driving performance in individuals with confirmed postprandial hyperinsulinaemic hypoglycaemia after gastric-bypass surgery.

Reducing hypoglycemia is an important aspect of management of type 1 diabetes (T1D) in older adults, many of whom have hypoglycemic unawareness, cognitive impairment, or both. Continuous Glucose Monitoring (CGM) offers the opportunity to reduce hypoglycemia and its related complications such as fractures from falls and hospitalizations and improve QOL including reducing hypoglycemic fear and diabetes distress. The potential benefit of CGM in reducing hypoglycemia in the older adult population has not been well studied. Prior and on-going trials compare CGM to self-monitoring of blood glucose levels, but none look at remote daily monitoring of CGM data or provision of telemedicine based on clinic notification of hypoglycemic events. This study is a 14 week, single center, pilot study of 10 subjects 65-75 yrs old with type 1 diabetes. The primary aim is to determine the effect of continuous remote CGM reporting coupled with a telemedicine intervention (Tele-CGM program) on rates of hypoglycemia in adults with T1D >65 years old. Study staff will review Tidepool uploads and call/email to the patient if one of the following occur has occurred in the past 24 hours: ≥4 hours without CGM signal, ≥2 hours 54 - 70 mg/dl and/or 15 minutes <54 mg/dl. Tele-monitoring call will include questions to find out why the event happened and then suggestions on how to trouble shoot to avoid issues in the future. As this is a feasibility study, statistical considerations were not used.
