Clinical Trial Summary

This study will evaluate the 2-5 year outcome of a cohort of 250 patients with early synovitis, who were recruited into protocol 94-AR-0194 (The Pathogenesis of Inflammatory Synovitis: A Study of Early Arthritis). Clinical, radiographic, and functional outcome parameters, particularly those relating to articular damage and functional loss, will be evaluated and related back to clinical, serologic, immunogenetic, and pathologic variables identified at the onset of the arthropathy. A model will be generated which incorporates and weighs the variables in order to determine diagnostic and prognostic markers in the early stages of arthritis. Synovial tissue samples have been obtained from the entire cohort at the initial visit of protocol 94-AR-0194. Studies of these biopsies have so far demonstrated evidence for the presence of infectious agents in a proportion of the samples, and have generated information regarding the cytokine profiles in the early stages of synovitis. In an attempt to further define the pathogenetic mechanisms of synovitis longitudinally, biopsies will be repeated on selected subsets of the cohort. Specific questions to be answered relate to the persistence of microbial agents in the synovium, and to the evolution of cellular and molecular mechanisms which mediate the invasive, destructive potential of the synovial lesion. It is anticipated that these studies should prove valuable to clinicians who are attempting to stratify patients for therapeutic strategies, early in their disease course. They should also prove valuable in enhancing the understanding of the pathogenetic mechanisms of synovitis.
