Title

Peripheral tryptophan, serotonin, kynurenine, and their metabolites in major depression: a case-control study

Overall design

The aim of this study was to extensively investigate plasma tryptophan levels and 10 metabolites of the serotonin and kynurenine pathways. A total of 173 patients suffering from a current major depressive episode (MDD group) and 214 healthy controls (control group) were recruited. Fasting plasma levels of peripheral metabolites, including tryptophan, serotonin, 5-hydroxytryptophan, 5-hydroxyindoleacetic acid, kynurenine, anthranilic acid, kynurenic acid, nicotinamide, picolinic acid, xanthurenic acid, and 3-hydroxyanthranilic acid, were quantified using ultra-performance liquid chromatography coupled with mass spectrometry.
