Impact of Changes in Muscle Secretome in the Remission of Type 2 Diabetes Mellitus Induced by Bariatric Surgery

Overview

Bariatric surgery is recognized as a therapeutic modality of type 2 diabetes. The mechanisms of this remission of diabetes remain poorly understood. The aim of our research is to characterize the changes in muscle secretome induced by bariatric surgery and to determine their role in improving the insulin sensitivity of skeletal muscle and insulin secretion by the B cell responsible for the remission of diabetes.

Detailed Description

Bariatric surgery is recognized as a therapeutic modality of type 2 diabetes. The mechanisms of this remission of diabetes remain poorly understood. The aim of our research is to characterize the changes in muscle secretome induced by bariatric surgery and to determine their role in improving the insulin sensitivity of skeletal muscle and insulin secretion by the B cell responsible for the remission of diabetes. This prospective study will be carried out in insulin-resistant diabetic patients or not in whom blood and muscle samples will be carried out before and after bariatric surgery

Interventions

  • Diagnostic Test: Muscle biopsy and blood test
    • Characterize the changes in muscle secretion induced by bariatric surgery and determine their role in improving the insulin sensitivity of skeletal muscle and insulin secretion by B cell responsible for the remission of diabetes mellitus.

Arms, Groups and Cohorts

  • Experimental: Muscle secretion
    • Characterize the changes in muscle secretion induced by bariatric surgery and determine their role in improving the insulin sensitivity of skeletal muscle and insulin secretion by B cell responsible for the remission of diabetes mellitus.

Clinical Trial Outcome Measures

Primary Measures

  • Changes in myokine (muscle secretome) secretion induced by bariatric surgery
    • Time Frame: Level of myokines in culture media conditioned by muscle cells taken before and 3 months after bariatric surgery.
