kynurenine and Diarrhea

kynurenine has been researched along with Diarrhea in 7 studies

Kynurenine: A metabolite of the essential amino acid tryptophan metabolized via the tryptophan-kynurenine pathway.
kynurenine : A ketone that is alanine in which one of the methyl hydrogens is substituted by a 2-aminobenzoyl group.

Diarrhea: An increased liquidity or decreased consistency of FECES, such as running stool. Fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. Diarrhea is not hyperdefecation or increased fecal weight.

" The purpose of this study was to evaluate the efficacy of a low-FODMAP diet with a concomitant reduction in tryptophan (TRP) intake in irritable bowel syndrome with diarrhea predominance (IBS-D) in relation to its metabolism via the serotonin and kynurenine pathways."9.69The Usefulness of the Low-FODMAP Diet with Limited Tryptophan Intake in the Treatment of Diarrhea-Predominant Irritable Bowel Syndrome.

"Irregularities of serotonin function in irritable bowel syndrome (IBS) may be due to changes in the metabolism of the serotonin precursor l-tryptophan."9.14Increased serum free tryptophan in patients with diarrhea-predominant irritable bowel syndrome.

"Our objectives are to demonstrate whether the kynurenine pathway is activated in diarrhea-type irritable bowel syndrome (IBS-D) patients, and whether the neurotoxic metabolite quinolinic acid (QUIN) is out of balance with the neuroprotective metabolite kynurenic acid (KYNA), and further explore whether this can lead to increase of N-methyl D-aspartate receptor 2B (NMDAR2B) expression in the enteric nervous system and in turn leads to intestinal symptoms and mood disorders."7.96Characterization of kynurenine pathway in patients with diarrhea-predominant irritable bowel syndrome.
