Active clinical trials for "Hypoglycemia"

The purpose of this study is to assess the burden of hypoglycemia and identify unmet need related to the management of hypoglycemia among Type 2Diabetes Mellitus (T2DM) patients on OADs and/or insulin. This is an observational study which will identify patients with T2DM in an administrative claims database and will link claims data with results of patient and physician surveys concerning hypoglycemia.

This is a non-interventional, cross sectional, multicentric study in T2DM patients which will involve a single visit for study related procedures. This study will be conducted in approximately 5,000 patients at around 300 hospitals/primary care clinics across India. Approximately 18-20 patients per site will be enrolled. This study has been designed to evaluate diabetes related quality of life (DQoL), frequency and impact of hypoglycaemia in relation to HbA1c control and to assess disease modifying variables-BMI and BP in T2DM patients on oral / injectable anti-diabetic drugs with/without insulin therapy.

This survey is conducted in South America. The aim of this survey is to investigate hypoglycaemia among Insulin-treated patients with diabetes.

Hypoglycaemia is associated with characteristic changes in the EEG with the appearance of slow frequency waves. In a recent study the investigators have shown that these changes can be recorded from subcutaneous electrodes and processed by an automated mathematical algorithm based on non-linear spectral analysis, and that changes are present before the occurrence of severe hypoglycaemia in type 1 diabetes patients. An alarm device based on real-time analysis of continuous EEG-recordings may thus be possible. For many diabetes patients nocturnal hypoglycaemia is a feared complication which may thus be preventable.

Long-acting insulin injected at bedtime may cause hypoglycemia (low blood sugar) in the night in patients with diabetes. The aims of the study are 1) to compare the dynamic characteristics of long-acting insulin analog glargine with those of NPH insulin and placebo during the night and the early morning hours, 2) investigate differences on glucose metabolism of bedtime glargine versus NPH insulin at induced hypoglycemia.

This study will help determine the frequency and magnitude of nocturnal hypoglycemia (low blood sugar at night during sleep), in children with type 1 diabetes who are on a standard insulin regimen, by using a Continuous Glucose Monitoring System (CGMS). Secondary objectives include the establishment of a definition of nocturnal hypoglycemia for the CGMS and for the calculation of sample size needed for future studies using CGMS. Nocturnal hypoglycemia (NH) can be associated with significant morbidity including seizure and coma. The investigators intend to use the CGMS in a future study investigating the use of a new insulin combination aimed to decrease the frequency of NH in the pediatric population. Thirty pediatric subjects with established type 1 diabetes mellitus will be asked to wear a CGMS for 3 days. During this time the participants will be required to test and record self-monitored blood glucose readings at designated time periods and if they have symptoms of hypoglycemia. The comparison of these values with each other and with different previously defined values of NH will allow for a clear definition of NH to be made. A survey has also been designed to assess participant satisfaction with the CGMS.

The Minimed®640G system (MM640G) consists of a combination of insulin and glucose sensor for continuous glucose monitoring (CGM). Here, the glucose sensor transmits not only the continuous glucose data on the display of insulin pump but, in the case of hypoglycemia also interrupt their insulin delivery of pump. In the currently available system Paradigm®VEO, the interruption takes place at a settled threshold level. In difference in the new system MM640G the shutdown algorithm can already be proactive and help avoid hypoglycemia completely. The so called PLGM algorithm (predictive low glucose management) should be tested in the user evaluation. The main objective is to answer the question of reducing the rate of hypoglycemia by application of the new PLGM algorithm. Included are a total of 24 patients, aged 1-21 years, in three pediatric diabetes centers.

Subjects with type 1 diabetes will be observed in the diabetes research center clinic following a meal and an insulin injection. Breath and sweat samples will be collected at intervals throughout the visit, with increased frequency during hypoglycemia. Collaborators with the MITRE Corporation will perform analyses on these samples to identify any relationships between volatile organic compounds in breath and sweat and hypoglycemia.

Diabetes is a major public health problem that has been growing steadily in recent years. Its prevalence is very high in the elderly, in whom there is an increased risk of hypoglycemia. Hypoglycaemia in elderly diabetics has serious consequences: increased mortality, increased cardiovascular morbidity, increased risk of falling, impairment of quality of life. Hypoglycaemia is also a risk factor for dementia in type 2 diabetes. The frequency of asymptomatic and atypical hypoglycemia has been shown to be greater in the elderly, but the exact prevalence of hypoglycemia in the elderly remains unknown. Elderly diabetic patients in institutions are particularly fragile and have more frequent cognitive problems than non-diabetic subjects. A study conducted in this population of patients showed that a third of them had HbA1C <6.5%, which suggests a higher frequency of hypoglycemia though the figures were not available. We therefore decided to conduct a study to assess the frequency of hypoglycemia in order to better understand the contributing factors and to improve the management of this fragile population.

The primary objective of this study is to evaluate the utility of [18F]-DOPA PET to provide improved presurgical planning and distinguish between focal and diffuse forms of HI. The investigators will perform descriptive analysis, relying on visual analysis to diagnose and localize a focal lesion. Our findings will be compared to surgical histopathology to determine sensitivity and specificity or this technique. The investigators will also track patient surgical outcomes, specifically whether the patient is surgically "cured" or still requires medical management to control residual hypoglycemia.
