Active clinical trials for "Diabetes Mellitus, Type 1"

This study is conducted in Asia. The aim of this observational study is to evaluate current status of diabetes management, control, complications in diabetic subjects in Thailand.

LO5 study: The investigators are inviting a new group of youth (ages 7-16) who have been recently diagnosed with type 1 diabetes and their non-diabetic siblings. These youth will complete cognitive tests and a MRI scan of the brain. This scan uses strong magnets to obtain pictures and does not involve any radiation or injections. The investigators will recruit patients within three months of their diagnosis date. The study entails 1 study visit that lasts 3.5 hours. Evening and weekend times are available. The investigators plan to enroll 135 participants. HY5 study: The investigators are inviting a cohort of youth and young adults (ages 9-21) with type 1 diabetes and their non-diabetic siblings for a follow-up to a study they have already completed. This group of people will complete several memory and thinking tests along with several MRI scans of their brain, just as they did at their previous visits. The investigators plan to enroll 150 participants.

This trial is conducted in Europe. The aim of this observational study is to evaluate the blood glucose control (HbA1c) using NovoRapid® (insulin aspart) and Levemir® (insulin detemir) after switch from human insulins for treatment of type 1 diabetes under normal clinical practice conditions in Romania.

This study is conducted in Asia. The aim of this observational study is to describe the diabetes management, control status and complication profile in a diabetic population of Philippines.

This is an observational study designed to help researchers understand the genetics and pathogenesis of type 1 diabetes, and to identify biomarkers for disease and disease complication prediction.

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.

This is a mono-centre trial performed at the Center for Clinical Research at the Medical University Graz. There will be a screening information and a study visit.In the study visit arterialized venous blood glucose values will be monitored and subcutaneous sampling of interstitial fluid (ISF) with microdialysis for glucose determination will be performed. Additionally to the laboratory analysis of the subcutaneous glucose samples, the glucose will be measured with extracorporeal on-line sensors and two marketed devices (Guardian RT and Glucoday S).The study visit will last 30 hours starting with the insertion of microdialysis catheters in the abdominal subcutaneous tissue and the insertion of the catheters for the Glucoday S system and Guardian RT system. The primary hypothesis of the study is: Interstitial fluid glucose concentration profiles correlate to the arterialized venous blood glucose concentration profile in type 1 diabetic subjects.

A study designed to determine the appropriate doses of Oral HDV Insulin at meal times.

The landmark study Diabetes Control and Complication Trial (DCCT) clearly showed that intensive insulin management delays the onset and progression of longterm complications in adolescents with type 1 diabetes mellitus (T1DM). The same clinic trial also showed increased rate of severe hypoglycemia which required assistance. The risks of severe hypoglycemia, defined as loss of consciousness or seizure associated with hypoglycemia, include lower HbA1C, younger age, higher insulin dose, male sex, lower parental socioeconomic status, non-Hispanic white ethnicity, longer duration of disease, the presence of psychiatric disorders, and underinsurance. The purpose of this protocol is to explore the relationship between hypoglycemic seizures and BMI.

The objectives of this study are to: quantitate the level of insulin mRNA in the while cell fraction of whole blood in selected groups of subjects, determine the gene expression of markers of white cell activation in the white cell fraction of whole blood in selected subjects, determine the identity of the white cell responsible for expression of insulin mRNA and determine protein expression of mRNA of insulin/proinsulin and selected genes of white cell activation.
