DEPLIPIDO Study: Functional and Lipidomic Analysis of Plasma HDL in Patients With Depression Compared to Controls

Study Overview
=================
Brief Summary
-----------------
Depression is a disabling condition in terms of psychosocial alteration and also in terms of physical comorbidities. Depression doubles the risk of myocardial infarction compared with the general population, and this cardiovascular comorbidity leads to an increase in mortality in patients suffering from depression, even exceeding suicide-related mortality. It is therefore important to better understand the mechanisms linking depression and cardiovascular disease. Among the hypotheses that may account for the increased cardiovascular risk in patients with depression, lipid abnormalities are likely to play a crucial role. Thus, qualitative and functional abnormalities in HDL lipoproteins are an important line of research, insofar as these lipid abnormalities have been recognized as important atherogenic abnormalities in populations at high cardiovascular risk, which is the case of patients with depression. In this clinical, epidemiological and scientific context, a collaborative study undertaken by both the Department of Psychiatry of the Dijon Bourgogne University Hospital of and the INSERM LNC-UMR 1231 (PADYS) Laboratory of the UNIVERSITY OF BOURGOGNE FRANCHE-COMTE is an original translational research project, and the first study to perform a lipidomic analysis of HDL, coupled with a functional analysis of these lipoproteins in depression.
