Effect of Hypoglycemia on Sleep
HypoglycemiaGrowing evidence provided by many observational studies has established a strong link between decreased sleep duration and poor glucoregulation. Sleep deprivation and poor sleep quality induce insulin resistance and decrease glucose tolerance in healthy individuals. However, the influence of poor sleep quality on glycemic control of patients with Type 1 diabetes mellitus (T1DM) is unknown. Persistent sleep deprivation among patients with T1DM has been reported, and this sleep loss can be attributed in part to nocturnal hypoglycemia. Nocturnal iatrogenic hypoglycemia is a limitation of current intensive insulin therapies. Although severe hypoglycemia is associated with adverse events such as seizures and death, less severe nocturnal hypoglycemia has been linked to broad range of adverse consequences, both acutely and long term. Hypoglycemia stimulates the sympathetic nervous system as a stress response, leading to the stimulation of the hypothalamic-pituitary-adrenal axis (HPA). This results in a counter regulatory hormone cascade, which elicits an excessive cortisol secretion, which is known to cause sleep disturbance and could impair glucose homeostasis after the hypoglycemic event. The hyperinsulinemia in T1DM patients promotes HPA hyperactivity as well, which is also associated with impaired sleep quality by leading to sleep fragmentation, decreased slow wave sleep and shortened sleep duration. Sleep disturbances due to nocturnal hypoglycemia can exacerbate HPA axis dysfunction, adversely affecting the sleep-wake cycle. The goal of the study is to understand the impact of nocturnal hypoglycemia on sleep.

Treatment of Hypoglycemia Following Gastric Bypass Surgery
HypoglycemiaObesity1 moreObesity is increasing worldwide and consequently the need for efficient treatment opportunities. Roux-en-Y gastric bypass (RYGB) is one of the most commonly performed bariatric procedures used in the treatment of severe obesity. The surgery results in significant and sustained weight loss and has a beneficial effect on blood glucose regulation. However, some patients experience the syndrome postprandial hyperinsulinemic hypoglycemia years after the operation, with symptoms varying from mild dizziness to confusion, loss of consciousness and seizures. Larger insulin and glucagon-like peptide 1 (GLP-1) responses to an oral glucose load are believed to play a role in the syndrome, which is not yet fully understood. There are no current treatment guidelines beside dietary recommendations. The purpose of this study is to compare different pharmacological treatments on daily blood glucose variations as well as postprandial hormonal and autonomous changes in subjects with symptoms of postprandial hyperinsulinemic hypoglycemia after RYGB.
Multiple Ascending Doses of ZP4207 Administered to HV to Evaluate the Safety, Tolerability, PKs...
HypoglycemiaThe trial is a single-centre, randomized, double-blind, phase 1b trial of multiple ascending doses of ZP4207 administered s.c. to healthy volunteers (HV) to evaluate the safety, tolerability, pharmakocinetic (PK) and pharmacodynamic (PD). Three cohorts of 8 subjects are planned. Within each cohort, the subjects will be randomly assigned to five repeated doses of ZP4207 or placebo in a 3:1 treatment allocation at trial site.
Clinical Usability of Nasal Glucagon in Treatment of Hypoglycemia in Children and Adolescents
HypoglycemiaDiabetes MellitusUp to fifty (50) children and adolescents with type 1 diabetes (T1D) aged 4 to ˂18 years at time of enrolment will be selected for inclusion in the study. The target is to obtain treatment response and user-experience data following use of Nasal Glucagon (LY900018) in treating episodes of hypoglycemia.
Glucagon Ready to Use (RTU) in Subjects With Hyperinsulinemic Hypoglycemia After Bariatric Surgery...
Hyperinsulinemic HypoglycemiaThis is a double-blind, placebo-controlled Phase 2 study to assess the efficacy, safety and tolerability of Glucagon RTU when administered to subjects with a history of bariatric surgery during episodes of post-postprandial hypoglycemia. Twelve eligible subjects will be randomly assigned to receive Glucagon RTU or placebo at the first of two clinical research center (CRC) visits, followed by the other treatment at the second CRC visit. Subjects will be randomly assigned to either Glucagon RTU or Placebo for the duration of a 12-week Outpatient Stage. A follow-up safety assessment visit will occur 14 to 28 days after a subject's last dose of study drug.
Effectiveness of Donor Human Milk Supplementation for the Treatment of Hypoglycemia in the Breastfed...
Neonatal HypoglycemiaThe purpose of this study is to compare if newborn infant hypoglycemia can be improved with bottle supplementation of commercially-sterilized donor human milk compared to standard infant formula. Hypothesis is that supplementation with commercially-sterilized donor human milk will improve hypoglycemia and limit formula use in exclusively breastfed infants.

Hyperinsulinemic HypoglycemiaPostprandial HypoglycemiaThe aim of this study is investigating the effect of a novel glucagon analogue administration in gastric bypass operated individuals, who are reactive hypoglycemic.
Dapagliflozin During Exercise for the PrevenTion of Hypoglycaemia
Diabetes MellitusType 1There are approximately 400,000 people in the UK who are living with type 1 diabetes (T1DM), of whom 29,000 are children. People with T1DM experience on average 2 episodes of symptomatic hypoglycaemia per week , and exercise (especially aerobic) increases this risk . Strategies to prevent hypoglycaemia during and after exercise include increasing glucose consumption and reducing insulin dose, however overcompensation may result in worsening of blood glucose control. Dysregulated glucagon secretion, manifested as a reduced counter-regulatory response during hypoglycaemia, is a key feature in T1DM, occurring soon after diagnosis. Anecdotal evidence suggests that SGLT-2 (sodium/glucose cotransporter-2) inhibitors (SGLT2i) such as dapagliflozin prevent exercise-induced hypoglycaemia in T1DM. SGLT2is promote glucose excretion without causing hypoglycaemia.Paradoxically, given their mode of action, they increase plasma glucose and stimulate glucagon secretion. Studies in diabetic rats indicate that the physiological counter-regulatory response is suppressed in insulin-treated diabetes, a defect that can be corrected by somatostatin antagonists. The DEPTH trial will test the novel hypothesis that hypoglycaemia results from hypersecretion of somatostatin, and that this defect can be corrected by SGLT2i. As these medications are already in clinical use, our findings may be rapidly translated into practice. Understanding these key processes has the potential to generate novel therapeutic strategies to improve glycaemic control, thereby facilitating a more active lifestyle in people with T1DM.
A Cognitive Behavioral Therapy (CBT) Intervention to Reduce Fear of Hypoglycemia in Type 1 Diabetes...
Type 1 Diabetes MellitusAll persons with type 1 diabetes are at risk for developing hypoglycemia (low blood sugar). This is a life-threatening condition that leads to profound fear of hypoglycemia and reduced quality of life. Fear of hypoglycemia results in glucose fluctuations (from high to low glucose levels). Young adults are particularly at risk because they report high levels of fear of hypoglycemia and poor glucose control. Currently, no diabetes self-management programs specifically address how to cope with fear of hypoglycemia. The investigators propose to pilot test a fear reduction intervention (Fear Reduction Efficacy Evaluation [FREE]) and its effects on fear of hypoglycemia, diabetes self-management, glucose control, and glucose variability.
