Targeting Glutamine Metabolism to Prevent Diabetic Cardiovascular Complications

The aim of the study is to investigate the role of glutamine metabolism in the pro-inflammatory activation of macrophages in diabetes and related cardiovascular complications. The study focuses on 3 adult patients' population with different diabetic status and level of cardiovascular risk: * Patients with uncomplicated type 1 or type 2 diabetes and low cardiovascular risk * Patients with uncomplicated type 1 or type 2 diabetes and high cardiovascular risk * Patients with complicated type 1 or type 2 diabetes Participants (n=975) will be recruited at clinical sites, in the diabetes and cardiology departments (APHP, Bichat - Claude-Bernard Hospital and APHP, Lariboisière Hospital), over a 2-year period. The study will consist in a single visit. During a scheduled hospitalization or consultation as part of the follow-up of their diabetes or as part of the follow-up of their cardiological problems, clinical data will be collected as well as additional blood and urine samples for analyses and biobanking. There will be no other intervention specific to the study.
