Growing evidence suggests that a dysregulation of the kynurenine pathway (KP) occurs in bipolar disorder (BD). This systematic review and meta-analysis aimed at assessing the possible differences in peripheral blood levels of KP metabolites between individuals with BD and healthy controls. We searched Medline, Embase, and PsycInfo electronic databases for articles indexed up to February 2020. We included any observational study comparing the peripheral blood levels of at least one KP metabolite… 

Tryptophan Catabolites in Bipolar Disorder: A Meta-Analysis

The TRYCAT pathway appears to be downregulated in bipolar disorder (BD) patients, and there is a need for more and high-quality studies of peripheral and central TRYCat levels, preferably using longitudinal designs.

The Role of Kynurenines in Cognitive Dysfunction in Bipolar Disorder

Future large-scale longitudinal studies are warranted to confirm the role of KYN metabolites in cognitive impairment in patients with BD and the possible therapeutic implications of this relationship.

Tryptophan Metabolism in Bipolar Disorder in a Longitudinal Setting

Investigation of tryptophan metabolism in bipolar disorder compared to controls (C), stratified by weight classes, in a longitudinal setting, indicates that tryPTophan, kynurenine, and IDO-1 activity may play a role in pathophysiology in BD but are not necessarily associated with clinical manifestations.

Blood concentrations of neopterin and biopterin in subjects with depression: A systematic review and meta-analysis

Is Poor Lithium Response in Individuals with Bipolar Disorder Associated with Increased Degradation of Tryptophan along the Kynurenine Pathway? Results of an Exploratory Study

The data indicate that lithium exerts anti-inflammatory effects by inhibiting indoleamine-2,3-dioxygenase (IDO)-1 activity and strengthens the assumption that the clinical drug response might be associated with biochemical processes.

Comprehensive Bibliometric Analysis of the Kynurenine Pathway in Mood Disorders: Focus on Gut Microbiota Research

A comprehensive bibliometric analysis of publications relating to the KP in MD provides an updated perspective on research associated with the KP, with a focus on the current status of GM research in this field.

Gut Microbiota – A Potential Contributor in the Pathogenesis of Bipolar Disorder

A review of the relationship between the GBA and brain function, the composition and changes of gut microbiota in patients with BD, and the potential role of GBA-related pathway in the pathogenesis of BD is explored to provide new ideas for the future etiology research and drug development.

Metabolomic Identification of Serum Exosome-Derived Biomarkers for Bipolar Disorder

The findings for the first time revealed a potential role of exosomal metabolite dysregulations in the onset and/or development of BD and suggested that bloodExosomal metabolites are strong candidates to inform the diagnosis of BD.



Kynurenic Acid in Schizophrenia: A Systematic Review and Meta-analysis

Overall, KYNA levels are increased in patients with schizophrenia, specifically within the central nervous system, and an improved understanding of KYNA in Patients with schizophrenia may contribute to the development of novel diagnostic approaches and therapeutic strategies.

Peripheral and central levels of kynurenic acid in bipolar disorder subjects and healthy controls

These findings implicate brain-specific regulation of KYNA under physiological as well as under pathophysiological conditions and strengthen the previous observation of CSF KYNA as a biomarker in BD.

The Metabolic Factor Kynurenic Acid of Kynurenine Pathway Predicts Major Depressive Disorder

This study provides a new diagnostic method to study MDD based on plasma KYNA level, and suggests that KYNA would be a potential biomarker in diagnosing depression patients.

Metabolic dysfunctions in the kynurenine pathway, noradrenergic and purine metabolism in schizophrenia and bipolar disorders

The present results suggest the kynurenine pathway of tryptophan metabolism, noradrenergic and purinergic system dysfunction as trait factors in schizophrenia spectrum and bipolar disorders.

Tryptophan and Kynurenine Metabolites: Are They Related to Depression?

Findings are opposite to expectations and not consistent with a hypothesized increased conversion from TRY to KYN in depressed subjects, and there is no evidence of altered production of serotonin as 5-HIAA concentration was unchanged.

Meta-analysis of Cerebrospinal Fluid Cytokine and Tryptophan Catabolite Alterations in Psychiatric Patients: Comparisons Between Schizophrenia, Bipolar Disorder, and Depression

There is preliminary evidence for similarities in the pattern of CSF cytokine and tryptophan catabolite alterations across major psychiatric disorders, although findings must be interpreted with caution in light of small numbers of studies/subjects.
