A study found DNA methylation profiling may predict if a patient will progress from a diagnosis of undifferentiated arthritis to that of rheumatoid arthritis (RA). The findings also suggest a pre-established epigenetic signature exists in patients diagnosed with undifferentiated arthritis that evolves into RA.
Disease outcomes in rheumatoid arthritis (RA) have improved dramatically since the introduction of biologic agents and improved treatment strategies. Nevertheless, the majority of patients still require prolonged, if not lifelong, therapy. Therefore, the ultimate goal would be to prevent RA. This study analyzed the effect of a one-year course of methotrexate in high-risk UA patients (studied in a previous trial) after post-randomization exclusion of patients without a high risk of developing RA…
