Filter by:Rationale: Hypoglycaemia is the most frequent complication of insulin treatment in individuals with type 1 diabetes and a limiting factor for achieving optimal glycaemic control. When recurrent, hypoglycaemia can induce a process of habituation, leading to impaired awareness of hypoglycaemia (IAH), a process that can be reversed by meticulous avoidance of hypoglycaemia. In the past 5-10 years, the use of continuous real-time (RT-CGM) or flash glucose monitoring (FGM) has increased rapidly in the clinical management of type 1 diabetes to improve overall glycaemic control and reduce the frequency of hypoglycaemic events, in particular in patients with IAH. It is unknown, however, whether the use of these devices, as well as other improvements in clinical management, has reduced the prevalence IAH and exposure to severe hypoglycaemia (SH) in subjects with type 1 diabetes in a real-world setting. Therefore, it becomes highly appropriate to investigate the current state of IAH and SH in type 1 diabetes. Also, since invites to this study will specifically include people who have taken part of previous assessments, this study will be able to investigate the change in IAH over time and the potential contributing role of RT-CGM/FGM. Furthermore, we want to explore associations of IAH and SH with clinical parameters, quality of life and psychosocial impact. This knowledge will help people with diabetes and their healthcare providers to better adjust treatment recommendations to individual targets. Objective: The primary objective of our study is to investigate the current prevalence of IAH and exposure to severe hypoglycaemia in individuals with diabetes type 1. The secondary objectives of our study are to: - Study the difference in IAH prevalence over time in individuals with diabetes type 1. - Assess the association of RT-CGM/FGM with IAH and SH. - Study thoughts, emotions and worries which lead to a certain behaviour in case of hypoglycaemia and prevention of hypoglycaemia. - Study associations of IAH and history of SH with productivity in different situations (work/study, relation/sexuality, driving behaviour/traffic and sport/leisure). - Study association between partner involvement and handling in case of (unawareness for) hypoglycaemia. - Study knowledge of subjects with diabetes about hypoglycaemia and IAH. - Study burden of IAH and severe hypoglycaemia on family members of people with type 1 diabetes, as experienced by patients themselves. Study design: This study will be a cross-sectional observational cohort study. The study will be conducted at the Radboud university medical center, department of internal medicine. Subjects with type 1 diabetes will be recruited from outpatient diabetes clinic as well as subjects who participated in two earlier cohorts and agreed to be approached again. Study population: The study population will be individuals with diabetes type 1, older than sixteen years old. Main study parameters/endpoints The main study parameter will be the current prevalence of IAH and exposure to severe hypoglycaemia in the past 12 months.
Hypoglycaemia or low blood glucose, and its fear are major barriers to achieving optimal glucose control. New technology, such as continuous glucose monitors (CGM), help to better identify hypoglycaemia and develop strategies to avoid it. These devices measure glucose in the skin, rather than in the blood, and provide information not only on how low glucose is, but also for how long. Recent studies showed that over half of episodes of low glucose with these systems are not recognised by people with diabetes, and even people without diabetes have sensor values that are below the current thresholds for hypoglycaemia [ low blood glucose] that we measure with traditional monitors. In this study, the investigators will evaluate the impact of symptomatic as well as asymptomatic episodes of low sensor glucose on a variety of clinical, patient-related and health economic outcomes such as mood, quality of sleep and productivity. The investigators will test different levels and durations of low sensor glucose to identify the one that best matches episodes that are symptomatic to best define hypoglycaemia using these systems. The investigators will also look at factors that influence this such as sleep or activity as well as diabetes management behaviours (such as insulin dosing, carb counting, etc). At the end of this study, the investigators will be able to provide a better definition of clinically relevant low sensor glucose readings that will help inform clinical as well as academic interpretation of CGM data.
This study is a RCT of 3 month at home comparing closed-loop control (CLC) system vs sensor and pump therapy (S&P), with a 3-month extension phase, in Type 1 diabetic patient prone to hypoglycemia. After a 2-week run-in phase with blinded CGM, patients who spent 5% or more time below 70mg/dL will be eligible to continue. They will will be randomly assigned 2:1 to the use of closed-loop control (CLC) using Tandem Control-IQ vs S&P for 3 months, which is the timing of the primary outcome for the RCT. After 3 months, the S&P group will use CLC for up to 3 months and the CLC group will continue using CLC for up to 3 additional months.
There are evidences that some healthcare teams are not proposing new therapeutic and technology options that have the potential to reduce hypoglycemia for people with type 1 diabetes. In practice, people living with type 1 diabetes report receiving education related to insulin pumps usage mainly on key functions (how the device works) at initiation and not enough about proactive adjustments (how to optimally use the device) especially on the long-term. In brief, short-term education is technical and product-specific, rather than being based on patients' needs.There is a need to test the efficacy of different programs that may be more suited to patients' needs and desires while offering the opportunity to reduce costs (e.g. web based). Since there is a lack of expertise related to optimal use of new technologies and therapies for people living with type 1 diabetes, we propose to design and test a web-based training (e.g. courses including videos and quizzes) and support (e.g. discussion forum) platform. This will be tested through a registry-based trial. The overall purpose of this study is to evaluate, among a group of adults living with type 1 diabetes, the SUPPORT online education platform in terms of users' satisfaction, engagement and efficacy to change the fear and the frequency of hypoglycemia.
Hypoglycemia is the most common diabetes-related adverse event. However, it is often under-reported to healthcare providers by patients and simultaneously, not often asked about by healthcare providers. As a result, little is known about how often hypoglycemia occurs and consequently, which individuals with diabetes will experience such events. The aims of this study are to determine the real- world occurrence of hypoglycemia and develop/validate real-world risk prediction models for hypoglycemia. These risk prediction models will generate a risk score that indicates an individual's risk for hypoglycemia given their socio-demographic, clinical, and/or behaviour-related characteristics. They can be used to promote clinician awareness around patients' hypoglycemia risks, guide point- of-care and patient decision-making with regard to treatment changes, inform the development and conduct of population-based interventions, and lead to tailored, cost-effective management strategies.
Eating Disorders (ED) are a major public health problem. Current care remains only partially effective and the pathophysiology of the disorders remains to be deepened. With regard to compulsive ED (bulimia and binge eating disorder), our clinical experience suggests that one of the major triggers for crisis may be related to glycemia. In fact, bulimia could be considered as a vicious circle where the binge eating disorder is going to be followed by a food restriction in order to control weight , putting the subject in a situation of "energy deficiency" which will favor the emergence of new crises . Technological advances have resulted in the emergence of new measuring devices, such as "tracking", which records continuous glycemia, which would allow us to explore these clinical hypotheses.
Hypoglycemic complications are a major impediment to the maintenance of healthy glucose levels in persons with diabetes. The investigators recently completed a clinical pilot and feasibility study (GLIMPSE, NCT02690168), which identified a novel biomarker, glial acetate metabolism, that appears to predict the susceptibility to hypoglycemia. By providing an assay to predict hypoglycemic events and therefore diabetic complications, the development of this biomarker could significantly improve the treatment of persons with diabetes. The goal of this study is to determine the efficacy of our biomarker for predicting susceptibility to insulin-induced hypoglycemia. In order to accomplish this goal the investigatiors will pair our 13C magnetic resonance spectroscopy procedure to assess glial acetate metabolism, developed in the GLIMPSE study, with a hyperinsulinemic-hypoglycemic clamp procedure, developed in the HYPOCLAMP study (NCT03839511). The two procedures will be separated by a three day interval. The investigators will then correlate the participants' rates of glial acetate metabolism with their neuroendocrine responses to the hypoglycemic clamp. This proof of concept study will test the hypothesis that glial acetate metabolism is inversely proportional to the neuroendocrine response to hypoglycemia, that is, as glial acetate metabolism increases the neuroendocrine response will decrease.

This proof-of-principle study to assess effects of different doses (mini and micro) of subcutaneous glucagon analog Dasiglucagon (Zealand Pharma, Copenhagen, Denmark) on the change in blood glucose concentration during moderate-intensity exercise in people with T1D.
Neonatal hypoglycemia understood as a reduction in plasma glucose can result in long-term neurological damage. Serious monitoring of neonatal blood glucose is indicated in patients at risk of hypoglycemia. Glycaemic monitoring in the newborn at risk should be started not before of the two hours of life, in fact at birth the neonatal blood glucose values are very low because they are conditioned by the metabolic activity of the foetus in the intrauterine phase, while later these values rise again until arrive at similar values to the adult within 48-72 hours. In recent years, various research groups have been evaluating the possibility of arriving at non-pharmacological prophylaxis of hypoglycemia. In particular, the Hegarty group has set up a protocol that uses dextrose gel at 40% in the risk categories that could reduce the number of hypoglycemia cases and consequently of painful procedures. In 2013 Harris et al. conducted a study to evaluate the failure rate in the treatment of hypoglycaemia in a sample of 242 newborns assigned in the 1:1 ratio to case or control group. The cases were treated with 40% dextrose in gel with a concentration of 200 mg/kg while the controls with a placebo solution. Newborns of both groups were encouraged to feed but if the feeding was insufficient, it was administered breast milk or formula milk through a syringe. Treated group showed a failure rate in reversion of lower hypoglycaemia compared to controls (14% vs 24%, RR = 0.57 (0.33-0.98), p = 0.04). Hegarty et al conducted a clinical trial in which 416 newborns were randomized and assigned to one of 4 types of treatment: dextrose 40% in gel in a single-dose (200 mg/kg) or double-dose (400 mg/kg ) 1 hour after birth or followed by 3 additional doses of dextrose (200 mg/kg) in the first 12 hours. Blood glucose was measured at 2 hours from birth then every 2-4 hours for the first 12 hours of life. The incidence of hypoglycaemia was lower in the treated than in the control group treated with a placebo solution (41% vs 52%, RR = 0.79 (0.64-0.98), p = 0.03). The group of newborns treated with a single administration of gel at a concentration of 200 mg/kg showed a greater reduction in the incidence of hypoglycaemia compared to the other types of treatment (38% vs 56%, RR = 0.66 (0.47-0.99), p=0.04)
