Effect of Agonist GLP1 on Adipose Tissue in Patients Undergoing Bariatric Surgery (Maigrir_OT)
March 15, 2024 updated by: Centre Hospitalier Universitaire de Nice
Normalizing weight gain and preventing the redistribution of body fat is a major health issue, and could help prevent the onset of various symptoms of metabolic syndrome.
Above all, it is important to understand the mechanisms by which these different treatments affect adipose tissue.
To this end, the investigators will first study the impact of GLP-1 analogues on adipose tissue.
The main objective is to show that subjects treated with a GLP-1 agonist have a significant change in their oxytocin levels compared with subjects not treated with a GLP-1 agonist.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: whole blood in a GLP1
Oxytocyne assay in a GLP1 analogue or non-analogue patient population
|
On the day of surgery, the surgeon will remove visceral adipose tissue (1 cm3) from the operative waste.
The adipose tissue is separated into 2 samples, one frozen in nitrogen, the other embedded in formalin.
The samples are then sent to the Institut de Biologie de Valrose (iBV) to assess any differences between the two groups of patients (patients treated with anti-GLP-1 analogues
