Filter by: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.
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.
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)
Hypoglycemia (HG) is common and can be dangerous in diabetes mellitus, so identifying patients at risk may lead to useful preventive strategies and improved quality of care and health outcomes. This study will test the implementation of a computerized alert tool for clinicians.
Observational, within-subject, crossover study To assess the impact of Dexcom G6 RT-CGM with a predictive hypoglycaemia alert function on the frequency, duration and severity of hypoglycaemia occurring before, during and after regular physical activity in people with type 1 diabetes At Imperial College Healthcare NHS Trust have established the multi-disciplinary Imperial Physical Activity and Diabetes (IPAD) clinic to empower, educate and enable people with diabetes to manage their blood glucose when they undertake physical activity. The investigator utilise the skills and expertise of a consultant diabetologist, a diabetes dietitian, a consultant in sports & exercise medicine, and a diabetes specialist nurse with expertise in diabetes technology. The investigator have access to diagnostic & therapeutic radiology, physiotherapy and psychology services.
In the effort of better understanding the glucose control in people with type 1 diabetes, in-depth insight into the physiology of hepatic glucose production and its influencing factors is essential. Previously, a number of potential influencing factors of hepatic glucose production have been investigated, including insulin-on-board, low carbohydrate diet, preceding ethanol intake, exercise and multiple stimulations of hepatic glucose production. Previous post-hoc analysis of dual-hormone closed-loop systems has indicated that the rate of fall in blood glucose influences the following stimulation of hepatic glucose response. However, the rate of fall in blood glucose is highly related to insulin levels, which may explain those findings. Thus, in this study the investigators want to examine whether the different rates of fall in blood glucose with similar insulin levels on board affect the hepatic glucose response in individuals with type 1 diabetes. In the study, which will be conducted at Steno Diabetes Center Copenhagen, participants will complete two study visits. On each visit, a hypoglycemic clamp technique will be used to lower the blood glucose levels of the participants (using either a rapid or slow decline rate), whereupon hepatic glucose production will be stimulated using low-dose glucagon. The study days are divided into four phases: 1) preparation phase, 2) hyperinsulinemic euglycemic phase (stabilization of blood glucose), 3) hyperinsulinemic hypoglycemic phase (rapid or slow decline in blood glucose) and 4) post-glucagon administration phase. This design will allow the investigators to examine whether differences in hepatic glucose response exist depending on preceding rate of fall in blood glucose. We hypothesize that the rate of fall in blood glucose does not affect the hepatic glucose production.
According to the Standards of Medical Care in Diabetes by the American Diabetes Association, people with diabetes should aim for 30 minutes of moderate-to-vigorous intensity aerobic exercise at least 5 days a week or a total of 150 minutes per week and doing some type of strength training at least 2 times per week in addition to aerobic activity. However, the effects of different forms and intervals of exercise on glycemic control are not well established. Exercise increases the risk of hypoglycemia both during and several hours after exercise. There are several strategies to avoid hypoglycemia during exercise. The most common strategy is to reduce insulin and to take carbohydrates before the exercise starts. Short-acting insulin analogs have a duration of approximately four hours, thus reductions need to be planned and done well in advance before the exercise starts. Since different types of exercise (aerobic, strength training or high intensity training) affect blood glucose in different ways and most exercise sessions include a combination of the types, these strategies are often associated with difficulties in obtaining stable blood glucose. The American Diabetes Association guidelines do not explicitly recommend a daily workout routine but outline recommendations for weekly amounts of exercise as there is currently insufficient evidence on the ideal timing, frequency and duration of exercise for preventing hypoglycemia. Hypothesis: in people with type 1 diabetes, time in hypoglycemia can be reduced if exercise is performed daily over five consecutive days compared to the same total amount of exercise performed at 2 days with at least 2 days interval. Aim: to evaluate the impact of the same total amount of exercise split into either five consecutive sessions or two sessions with at least 2 days in between on percentage of time spent in hypoglycemia and other glycemic parameters in people with type 1 diabetes.
This study involves two parts: a randomised controlled trial, and a nested qualitative study. The main aim of the trial is to evaluate the effectiveness of a pharmacist-led, medications-focused patient counselling on reducing the frequency of hypoglycaemia in older adults diagnosed with type 2 Diabetes Mellitus within 12 weeks in Jordan. The study hypothesis is that individualised patient counselling which is provided by pharmacists and involves recommendations about anti-diabetic medications will reduce the risk of hypoglycaemia by preventing further episodes in the elderly Jordanians with type 2 Diabetes Mellitus. The qualitative study aims at evaluating the experience of participants in both groups with the study (process evaluation). This involves exploring which components are effective and which are not with the reasons, the contextual factors affecting the delivery and implementation of the study and the intervention, and how the study and the intervention can be scaled up in the future.
The overall objective of this study is to investigate whether hypoglycaemia (the most potent stimulus of pancreatic glucagon secretion) affects the secretion of gut-derived glucagon in totally pancreatectomized patients.
Despite recent pharmacological and technological advantages, hypoglycemia remains to be the key limiting factor in achieving optimal glycemic control in people with type 1 diabetes. State-of-the-art treatment for type 1 diabetes is insulin in pens or pumps that focus on reducing hyperglycemia after relative insulin deficiency e.g. after food intake. In recent years, we focused on adding low-dose glucagon to insulin therapies for the treatment and prevention of hypoglycemia - referred to as "dual-hormone treatment". We have shown that low-dose glucagon is efficient in treating mild hypoglycemia and that several factors may affect its glucose response. Our next step is to test whether the combined delivery of insulin and glucagon can improve glucose control in individuals with type 1 diabetes. In this proposal, we want to test the efficacy, safety and feasibility of a dual-hormone closed-loop system, also known as an artificial pancreas. The closed-loop system involves automatic infusion of glucagon and insulin based on continuous glucose measurements. The system will be tested in a 33-hour in-clinic study comparing the glucose control by the combined automatic delivery of insulin and glucagon with the automatic delivery of insulin-only. The study is performed at Steno Diabetes Center Copenhagen (SDCC) in collaboration with the Technical University of Denmark (DTU). We expect that the study will clarify whether low-dose glucagon added to insulin therapy can improve the glucose control in adults with type 1 diabetes. We believe that the utilization of glucagon will allow for a weight neutral optimization of glucose control, reduce risk of hypoglycemia and reduce disease burden that will reduce diabetes complications and cardiovascular diseases.
