Researchers are looking for a better way to help Chinese people who have diabetes to monitor their blood sugar (blood glucose) situation. There are 2 types of diabetes. In people with type 1 diabetes, the body's immune system attacks and destroys cells in the pancreas that produce a hormone called insulin. In people with type 2 diabetes, the body does not make enough insulin or does not use insulin well. This results in high blood glucose levels. Over time, high blood glucose levels can cause damage to certain parts of the body. These include the eyes, the kidneys, the nerves, and the heart. There are tests and devices available for doctors and patients to measure blood glucose levels. Repeated measurements of blood glucose levels are needed to see whether the treatments that prevent blood glucose levels from becoming too high work well and to notice when the blood glucose is decreasing too much. Such tracking of the blood glucose is also called blood glucose monitoring. Blood glucose monitoring tests and devices can however be difficult to use, and one test or device may not work for all patients. Researchers think that better monitoring systems would help patients improve the control of their blood glucose levels. This could help stop their diabetes from getting worse. In this study, the researchers want to learn more about how well a new monitoring system called CGM works in Chinese patients with diabetes. CGM is a continuous glucose monitoring system. It regularly measures the level of glucose in the tissue throughout the day and night. CGM is made up of a small sensor that patients apply in the belly region where it is placed just under the skin, into the so-called subcutaneous tissue. The sensor measures the level of glucose in the fluid that surrounds cells in the subcutaneous tissue. It also has a transmitter which attaches to the sensor and sends via Bluetooth the results to a device, which can instantly display the glucose level. The glucose levels can then be used to adjust the treatment. The main purpose of this study is to learn how well CGM monitors glucose levels in Chinese patients when used in usual practice. To answer this question, the researchers will compare the glucose levels collected with the CGM monitor to the blood glucose levels collected with another type of monitoring called "venous blood glucose testing". This is where a blood sample is taken from the veins, and then the level of glucose in the blood sample is measured. The study will include adult Chinese patients who have type 1 or type 2 diabetes and who the study doctors think need to monitor their diabetes using CGM and venous blood glucose testing. There will be no treatments given as part of this study. The device will be worn up to a maximum of 14 days. The patients will get training on how to use the CGM monitor and will attach it to their belly on Day 1 of the study. The researchers will then collect the information about their glucose levels. The study doctors will also take blood samples and measure blood glucose levels using venous blood glucose testing. They will compare the glucose levels recorded from the blood samples to the glucose levels recorded by CGM at the closest time points. After wearing CGM for 14 days, the study doctors will remove it from the patients' bellies. About 3 days later, the researchers will call the patients to check if they have any swelling or areas of rash where CGM was worn. The patients may also take photos of the area and send these to the study doctors. During the study, the study staff will: - take blood samples as part of the usual care - compare glucose levels recorded by CGM to the levels recorded from the venous blood glucose tests - check the skin for any swelling or areas of rash where CGM was worn - record any instances of CGM errors or alarms for when glucose levels are too high or too low - check the patients' overall health - ask the patients about how they are feeling and what medical problems they are having.
The purpose of this study is to determine whether continuous glucose monitoring will improve glucose variability as measured by the coefficient of variation of glucose levels in very young children with T1D. The study adopts an open-label, multi-centre, multinational, prospective registry-based population cohort design contrasting CGM use to SMBG alone in young children with type 1 diabetes over 12 months. The primary endpoint is the difference between treatment modalities (CGM vs SMBG alone) in glycaemic variability, measured as the coefficient of variation of glucose levels, during the 12 months observational period. Other Key edpoints include time in range 70-180 mg/dl, time below range 70 mg/dl and time above range 180 mg/dl.
Prospective observational cohort study. Elderly patients >65 years with type 2 diabetes mellitus (T2DM) on insulin therapy and HbA1c between 7% and 9%, with or without oral agents, will be identified from medical records and invited to participate. Patients will wear a FreeStyle Libre Flash CGM during a 6-week study period. Using CGM technology, we will assess an efficacy outcome : time in range (TIR) between 70-180 mg/dl and a safety outcome: incidence of hypoglycemia (time below range (TBR) less than 70, 54, and 40 mg/dl in insulin treated older adults with T2DM. Patients will return to clinic every 2 weeks for new continuous glucose monitoring (CGM) placement, assessment of glycemic control and hypoglycemia, adherence to therapy and CGM use. CGM data will be downloaded every 2 weeks.
The aim is to investigate the correlation between mean glucose measured by continuous glucose monitoring (CGM) and mean glucose estimated from glycated haemoglobin A1c (HbA1c) in persons with type 2 diabetes undergoing peritoneal dialysis compared with patients with type 2 diabetes and normal renal function. Furthermore, the aim is to compare CGM and HbA1c with glycated albumin and fructosamine.
To validate the feasibility of a 15-day wear period of the Cascade CGM system
The purpose of this project is to investigate whether the glucose response in type 1 diabetes patients measured using Continuous Glucose Monitoring measurement is reproducible in repeated standardized test sessions that include physical activity.
Continuous glucose monitoring (CGM) methods provide details of magnitude and duration of glucose fluctuations, giving a unique insight on daily blood sugar control. Limited data are available on glucose variability (GV) in pregnancy. The aim of this study was to assess GV in normal pregnant women and cases of type 1 diabetes mellitus or gestational diabetes (GDM), and its possible association with HbA1c.
Achieving near-normoglycaemia has been established as the main objective for most patients with diabetes. However, it is well known that intensification of treatment is associated with an increase in the frequency of hypoglycemia, especially in the context of insulin therapy. The burden of hypoglycemia in terms of psychological implications, morbidity and even mortality, explains why it has been defined as the main limiting factor to achievement of good metabolic control. Continuous subcutaneous glucose monitoring (CGM) devices have been claimed to be useful in hypoglycemia detection/prevention, allowing theoretically for safer intensification of therapy in diabetic patients. However, accuracy of CGM devices, especially in the hypoglycemic range, raises some concerns. In fact, commercially available CGM devices estimate plasma glucose from measurements in the interstitial fluid and not in plasma. However, the relationship between plasma and interstitial glucose is not fully understood, especially under dynamic conditions, and this may explain the poor CGM performance during rapid changes in blood glucose and hypoglycemia. In this project, the relationship between plasma and interstitial glucose will be evaluated under conditions of normal glucose concentrations and hypoglycemia. Experiments will be performed to assess the role, if any, of different plasma insulin concentrations on the accuracy of CGM. All the information obtained may be relevant to the improvement of the ability of CGM devices to detect hypoglycemia and hypoglycemic risk.
