Brief Summary:
According to the WHO, major depressive disorders have become the second worldwide cause of disability. Treatment, long-term medication, leads to frequent resistance (up to 40%).
Establishing a cerebral molecular signature of depression is not feasible in humans (need for cerebral samples). The alternative is to use peripheral biological samples (blood, urine, saliva).
Metabolomic is the integrated and quantitative study of all the metabolites of a biological system. This aims to define the metabolic status of an organism for a particular condition.
Metabolites are derived from biological extracts (cells, tissues, serum, plasma, urine, etc.) and are detected by:
* liquid or gas chromatography coupled to mass spectrometry (LC-MS, GC-MS),
* proton nuclear magnetic resonance (1 H-NMR). The biomarkers resulting from these studies have become important diagnostic criteria, measured objectively and evaluated as indicators of a normal or pathological state, or even predictors of treatment efficacy.
This approach allows the discovery of biomarkers that best describe the status of a disease for better understanding and are usable in a context of individualized medicine, with effects on clinical practice and management.
