Primary Outcome Measures:
  • Type 2 Diabetes occurrence [ Time Frame: 5 years (or less if occurrence of the condition) ]
    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 this population

Secondary Outcome Measures:
  • Biomarkers [ Time Frame: 7 to 10 years ]
    To highlight biomarkers of prediabetes, type 2 diabetes and cardiometabolic diseases, through genomics, proteomics and transcriptomics analyses performed on a biological sample collection.

  • Number of patients with pre-diabetes in North of France [ Time Frame: 5 years ]
    To estimate the prevalence of prediabetes in the region Nord-Pas-de-Calais (France)

  • HbA1c measurement [ Time Frame: 5 years ]
    To evaluate the role of HbA1c in screening for pre-diabetes and type 2 diabetes

  • Diabetes Risk Score [ Time Frame: 5 years ]
    To assess the interest of Diabetes Risk Score (questionnaire used to evaluate a clinical risk) in identifying subjects at risk of type 2 diabetes

  • Others cardiovascular risk factors [ Time Frame: 5 years ]
    To measure the prevalence of other cardiovascular risk factors observed along with prediabetes: dyslipidemia, metabolic hepatopathy

Enrollment: 207
Study Start Date: September 2011
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Intervention Details:
    Other: Prediabetes screening and prospective follow-up over 5 years

    The study period per patient is 5 years. The planned schedule of the study is as follows :

    • Enrollment at visit V0 of subjects at high metabolic risk, based on a biological value (within the past 2 months) of moderate fasting hyperglycaemia (blood glucose ≥ 1,10 g/l and < 1,26 g/l) or fasting blood glucose ≥ 1 g/l and < 1,10 g/l with HbA1c ≥ 6,5%.
    • First biological sample (B0) within 1 month following V0 (measuring fasting blood glucose + glycated hemoglobin HbA1c + lipid profile + creatinemia + liver function; and establishment of a biological sample collection to identify biomarkers).
    • Annual follow-up for five years consisting in one blood sample (B1 to B5) measuring the same parameters as V0 + biological sample collection, and questionnaire on major health events or health events related to study procedures.

Detailed Description:
Type 2 diabetes (T2D) is a real public health issue, with an exponential incidence. Before its diagnosis, several physiopathological changes are already taking place, such as insulin resistance of target tissues and the progressive inability of pancreatic beta cells to produce insulin. The objective of this study is a better understanding of the prediabetic stage and mechanisms involved in the possible development of T2D, by way of a five-year follow-up cohort study in 207 prediabetic subjects.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Previous history (within 2 months prior to enrollment visit) of fasting blood glucose ≥ 1,10 g/l and < 1,26 g/l OR fasting blood glucose ≥ 1 g/l and < 1,10 g/l with HbA1c ≥ 6,5%.

Exclusion Criteria:

  • Fasting glycemia ≥ 1.26 g/l
  • History of treatment with oral antidiabetics
  • History of treatment with insulin, except gestational diabetes
  • Subject with any history or presence of significant hematologic (coagulation, thrombopenia, …), hepatic, renal, or psychiatric disorders
  • Subject unable to follow the study during the 5 years of follow-up
  • Subject in exclusion period of a previous study or simultaneously participating to any other clinical trial on metabolism
