- Brief Summary
More than half of all new cases of type 1 diabetes (T1D) are diagnosed in the first decade of life. It has been reported that early onset T1D may be associated with deterioration in cognitive performance. It mainly affects working memory or the ability to perform complex tasks involving planning (executive functions) or decision-making. Brain magnetic resonance imaging (MRI) has reported alteration brain growth alteration related to impaired cognitive performance. Exposure to hypoglycemia, hyperglycemia and glycemic variability are thought to be responsible for these structural changes, especially in younger patients. Those changes can be detected early after diagnosis. Automatized insulin delivery systems (AIDS) can dramatically improve glycemic profile in children with T1D by reducing the occurrence of hypo and hyperglycemia. However, in France, market authorization are limited to children with unbalanced T1D who have failed to respond to other therapies and to the reinforcement of diabetes education. It therefore does not concern newly diagnosed patients. 60% of patients under 10 diagnosed with T1DM for less than 3 years are not treated in France by these systems. The aim of this study is therefore to determine whether early treatment of patients with AIDS would have a positive impact on cerebral growth and and on cognitive function in pediatric patients with T1DM.
- Detailed Description
The aim of the study was to evaluate the neuroanatomical damage to gray matter associated with type 1 diabetes in young children according to their glycemic profile (use of a AIDS or not) and compared with an age-matched control subject.
Prospective case-control cohort study (T1DM or not) and exposed/non-exposed (CL or not), multicenter with 2 visits at 6 and 24 months of T1DM and 2 parallel visits for the control group.
The AIDS system used is a "mylife CamAPS application", marketed by CamDiab Ltd. class III, (YpsoPump, marketed by Ypsomed, Dexcom G6 blood glucose sensor, used in their respective indications).
One experimental group (AIDS group) and two comparator groups, Standard treatment group (TS group): patients with T1DM treated with insulin pump + blood glucose sensors and group C (control): age-matched control subjects without T1DM.
The expected benefits are early access to an automated insulin delivery system for study participants, as well as evidence of the neurocognitive benefit of early use of AIDs leading to changes in care practices.

- Primary Outcome Measures
Name Time Method volume of total gray matter measured with high-resolution morphometric MRI at inclusion and at 18 months after inclusion The primary endpoint will be changes in total gray matter volume measured with high-resolution morphometric MRI (vox based morphometry method).
It will be measured at randomization (within 6 months of diagnosis) and 18 months after randomization in the intervention group (treatment of T1DM with SADI), in a control group of T1DM patients (treatment of T1DM with insulin pump and blood glucose sensor) and in a group of non-diabetic control subjects in the same age range.
- Secondary Outcome Measures
Name Time Method Intelligence score at month 6 and 24 months after diagnosis of T1DM Assessment of neurocognitive performance: Scale scores Wechsler Intelligence Scale for Children (WIPPSI-IV)
Score of Nepsy II scale at month 6 and 24 months after diagnosis of T1DM Auditory attention test
Score of Stroop big small et Stropp fruits scale at month 6 and 24 months after diagnosis of T1DM Assessment of inhibitory control
volume of total gray matter measured with high-resolution morphometric MRI at month 6 and 24 months after diagnosis of T1DM Variation in other morphometric measures (localized gray matter, total and localized white matter, measurement of anatomical connectivity) and resting brain function (measurement of cerebral blood flow by arterial label spin ALS) will be compared between the two groups of diabetic children between randomization and the end of the 18-month intervention
glycemic variability indexes at month 6 and 24 months after diagnosis of T1DM Glycemic variability measured from data from continuous measurement of interstitial glycemia though the sensor worn by the patient. The standard deviation (SD) of the glycemic mean, the coefficient of variation (CV), the continuous overall net glycemic action (CONGA) 1 hour - 2 hours - 4 hours will be calculated from the full 72 hours recording closest to the visit. Their changes will be compared between the two measurement times between the groups.
Score of test "attention go/nogo" of KiTAP scale at month 6 and 24 months after diagnosis of T1DM Behavioral control assessment and focused attention test
Score on BRIEF ((behavioral assessment inventory) scale at month 6 and 24 months after diagnosis of T1DM behavioral assessment inventory
