Rheumatoid arthritis (RA) can be typed, grouped and categorized in different ways, and subgroup identification could help guide future research and treatment strategies based on which subtypes respond to which treatment. A new study explored an approach associating gene expression profiling with histologic analysis of synovium samples to define RA subtypes and then examined how…
NEW YORK (Reuters Health)—Synovial gene expression and histology can be used to divide rheumatoid arthritis (RA) into high, low, and mixed inflammatory subtypes, according to results from the Accelerating Medicine Partnership: RA/SLE Network. “The actionable implication of these findings is that it may be worth considering synovial biopsies in patients who are not responding to…
