Prospective Follow-up of a Cohort of Pre-diabetics in the North of France (DiabeNord)
DiabeNord: A 5-year Prospective Follow-up Cohort Study in Pre-diabetic Subjects for the Identification of New Biomarkers
The purpose of this study is to identify in prediabetic subjects, physiopathological changes involved in the evolution to type 2 diabetes mellitus and to identify new biomarkers of type 2 diabetes risk in this population.
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.

Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
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.
  • End of study visit
