Open Access Abstract Considering the relation between synovial inflammation and global disease activity in rheumatoid arthritis RA and the distinct but heterogeneous histology of spondyloarthropathy SpA synovitis the present study analyzed whether histopathological features of synovium reflect specific phenotypes and or global disease activity in SpA. Synovial biopsies obtained from 99 SpA and 86 RA patients with active knee synovitis were analyzed for 15 histological and immunohistochemical markers. Correlations with swollen joint count serum C-reactive protein concentrations and erythrocyte sedimentation rate were analyzed using classical and multiparameter statistics. SpA synovitis was characterized by higher vascularity and infiltration with CD163 macrophages and polymorphonuclear leukocytes PMNs and by lower values for lining-layer hyperplasia lymphoid aggregates CD1a cells intracellular citrullinated proteins and MHC-HC gp39 complexes than RA synovitis. .
