Tryptophan metabolism in rheumatoid arthritis is associated with rheumatoid factor and predicts joint pathology evaluated by the Rheumatoid Arthritis MRI Score (RAMRIS).

CONCLUSIONS: This study supports the hypothesis that tryptophan and its metabolites can be used as biomarkers predicting radiologic outcome and discriminate between RA and OA patients. Overall, our results strengthen the notion that tryptophan metabolism is closely linked to RA disease mechanisms. PMID: 30557125 [PubMed - as supplied by publisher]
