title: Evaluation of clinical and prognostic significance of T cell regulatory subsets in rheumatoid arthritis.
abstract: Phenotypic analysis of circulating lymphocytes and T cell subsets using monoclonal antibodies was performed on 60 patients with rheumatoid arthritis (RA). A significant lymphopenia was observed in RA patients and correlated with the use of disease suppressant drugs (p less than 0.0001). A significant decrease in the number of suppressor/cytotoxic T cells resulted in an increase in the TH/TS ratio in 40% of RA patients. This elevated ratio did not correlate with disease activity, the presence of extraarticular features, autoantibody production or immune complex formation. We conclude that the evaluation of the TH/TS ratio has no diagnostic or prognostic value.
