Link Between the Peripheral Mononuclear Cells' Capacity to Induce Insulin

Status Completed

Clinical Trial Summary

This is a two-center proof-of-concept study, ancillary to the MetACTIV study, whose objective is to define immune activation profiles from the data of individuals followed by the Caisse Primaire d'Assurance Maladie du Gard (health insurance fund). The IRACTIV study will include a subset of volunteers from the MetACTIV study for whom a blood sample will be taken as part of the IRACTIV study.

Clinical Trial Description

The local health insurance fund regularly offers people who have already had a free health check-up the opportunity to re-do a check-up. This invitation will be made as part of the routine, by mail. People who have participated in the MetACTIV study will be asked to participate in the present IRACTIV study ( they will be sent an information note). That way, up to 30 volunteers who previously participated in the MetACTIV study, including 10 for whom a particular profile has been identified will be recruited again in sequence. On the day of consultation at the Gard health insurance fund, consent will be collected from subjects who have agreed to participate. The participation of the volunteers will be reduced to this single visit and 16 mL of blood will be collected on EDTA for the purpose of this study. As in the previous MetACTIV study, this blood will be transported to the Biological Resource Center at Nîmes University Hospital. From this blood, the plasma will be frozen and stored at -80°C for subsequent determination of insulin levels under the same conditions as for the MetACTIV study. Peripheral blood mononuclear cells will be frozen and, later, cultured at the Institute of Human Genetics in complete medium for 48 hours. The effect of the supernatants of these cultures on Akt phosphorylation in HepG2 cells exposed to 10nM of insulin will then be quantified by two different techniques (Western Blot and ELISA). This effect will be expressed as a percentage of inhibition compared to the phosphorylation of Akt induced by insulin alone. The insulin slope between the measurement performed in the MetACTIV study and this IRACTIV study will also be calculated and compared to the peripheral blood mononuclear cells ability to induce insulin resistance in vitro. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
