About
There are few longitudinal studies in the Caucasian population and even less in the Italian population in subjects with impaired glucose regulation to allow:
In order to set up a longitudinal study capable of defining the above parameters it is mandatory that the physiological, biochemical, and, genetic markers specific for IGR are identified. The goals of the present research proposal are:
The subjects who will be identified will add up to other 900 individuals who will be recruited as part of a follow-up program sponsored by the Italian Society of Diabetes, specifically designed to assess conversion rate to diabetes.
Full description
The main goal of the present research program is to recruit about 600 new subjects with IGR to be added to the 900 subjects which are collected as part of the GENFIEV project which has been designed as a 6-yr follow-up study to ascertain the rate of conversion to type 2 diabetes in the Italian population. In particular the goal of the present research program will be to determine in a sample of the Italian population at greater risk for type 2 diabetes than the general population:
the pathophysiologic mechanisms responsible for the disorders of impaired glucose regulation (IGR). In particular we will evaluate insulin action and insulin secretion as a function of the degree of glucose tolerance by analyzing these parameters in normal subjects as well as in IFG/NGT, NFG/IGT, and IFG/IGT individuals; the biochemical markers associated with the disorders of impaired glucose regulation (IGR). In particular we will evaluate several biochemical parameters (lipid profile, coagulative profile, microlbuminuria, free-fatty acids, PAI-1, fibrinogen, creatinine, uric acid, HbA1c); the cardiovascular risk profile associated with the disorders of impaired glucose regulation (IGR). In particular, the relevant biochemical parameters will be integrated with measurements of arterial blood pressure as well as ECG recording; the genetic markers associated with the disorders of impaired glucose regulation (IGR). In particular subjects will be screened for HHEX, IGF2,BP2 CDKAL1,TCF2L7, CDKN2A/B,WFS1; the impact of environmental factors on the disorders of impaired glucose regulation (IGR).
Finally, we will endeavour to assess the cellular pathways that may be affected by metabolic alterations typically occurring in concomitance with the disorders of impaired glucose regulation (IGR).

Inclusion criteria
Each consecutive subject referred to a diabetes clinic for a diagnostic OGTT meeting the above criteria will be assessed as a potential candidate for the study till a total recruitment of 75 individuals will be reached.
Subjects who had both IFG and IGT will included as well.
Subjects with normal glucose tolerance (FPG <6.1 and 2-h PG <7.8 mmol/l) will be also recruited as controls
