What the trial is, and whether it could suit you
The HAGI-T1D study aims to determine the effect of improved glycemic control on the composition and function of high-density lipoproteins (HDL) in patients with type 1 diabetes (T1D). It requires the establishment of a biological plasma/serum bank.
T1D patients hospitalized in the Endocrinology-Diabetology-Metabolic Diseases Department at the Dijon Bourgogne University Hospital for poorly controlled diabetes (defined by glycated hemoglobin HbA1c \>8.0%).
The study includes a T1D group of 80 patients with unsatisfactory glycemic control, who will undergo intensified therapy in accordance with standard clinical practice (modification of insulin therapy, therapeutic education, and lifestyle and dietary guidelines). The study also includes a control group of 63 non-diabetic, non-dyslipidemic subjects enrolled based on the results of laboratory tests from the screening visit to assess wheth
