Abstract
To examine in a cohort of rheumatoid arthritis (RA) patients undergoing serial ultrasound (US)-guided biopsies of small joints in the context of clinical trials whether sufficient synovial tissue could be obtained at both baseline and second biopsy to: 1) accurately evaluate the synovial immune phenotype, 2) permit adequate RNA extraction to determine molecular signatures, and 3) sensitively detect change in the number of synovial sublining macrophages (CD68+) following effective therapy.File in questo prodotto:
