Primary Outcome Measures:
  • To identify new biomarkers [ Time Frame: 5 years ] [ Designated as safety issue: No ]
    The main objective of the study is to understand the pathophysiological mechanisms involved in switching from pre-diabetes to type 2 diabetes and to identify new biomarkers of type 2 diabetes risk in the population of patients with pre-diabetes


Secondary Outcome Measures:
  • To identify new therapeutic targets [ Time Frame: 5 years ] [ Designated as safety issue: No ]
    To identify new therapeutic targets for the prevention of the appearance of the diabetes in the population of patients with pre-diabetes

  • To connect identified biomarkers with the degree of insulinoresistance [ Time Frame: 5 years ] [ Designated as safety issue: No ]
    To connect identified biomarkers with the degree of insulinoresistance (HOMA-R) and with β pancreatic function (IOG) in the population of patients with pre-diabetes.

  • Number of patients with high Diabetes Risk Score and pre-diabetes [ Designated as safety issue: No ]
    To evaluate the interest of the Diabetes Risk Score in identifying subjects with pre-diabetes in the French population

  • Number of patients with others cardiovascular risk factors [ Time Frame: 5 years ] [ Designated as safety issue: No ]
    To evaluate the prevalence of others cardiovascular risk factors associated with pre-diabetes: dyslipidemia, hypertension, metabolic liver disease

Intervention Details:
    Other: Biopsies of muscular and fat tissue

    3 half days of metabolic exploration including blood sample, urinary taking, OGTT (oral glucose tolerance test), biopsies of muscular and fat tissue:

    • 1 visit the first year (inclusion visit)
    • 1 visit at the end of 5 years of follow-up or in the appearance of type 2 diabetes
    • 1 intermediary visit (in 3 years) or activated by the following conditions:

      • Escalation of the glycemia (increase of 0.1g / l of the glycemia and/or 0.3 % of the HbA1c)
      • Normalization of the glycemia (fasting blood glucose < 1 g/l)
