| Study Title | A Longitudinal Study in Rheumatoid Arthritis Unveils Metabolomic Biomarkers Preceding Clinical Onset, Assessing Disease Severity, and Anticipating Treatment Response to csDMARDs |
| Study Summary | Rheumatoid arthritis (RA) is a bundle of systemic inflammatory diseases mainly affecting the joints, complicating the identification of biomarkers for early diagnosis, predicting disease progress and therapeutic outcomes. This study scrutinizes a longitudinal cohort of RA, inclusive of follow-ups, alongside OA, UA and ACPA/RF-RA and healthy controls, aiming to discover plasma metabolic markers that can precede RA onset, assess disease activity, and forecast treatment efficacy. Our investigation revealed substantial metabolic alterations at both the pathway and individual metabolite levels across RA, at-risk or RA and healthy control. The drug response predictive models constructed on critical differential metaboites showed optimal performance. Additionally, our longitudinal data sheds light on the molecular impacts on metabolism of csDMARDs in RA. |
