We initiated allopurinol at low doses during an acute gout attack in patients who met criteria for starting urate-lowering therapy and did not have abnormal kidney or liver function. In this cohort, allopurinol did not prolong the acute, treated attack.

Accumulating evidence implicates a central role for synovial T cells in the pathogenesis of rheumatoid arthritis, but the activation pathways that drive proliferation and effector function of these cells are not known. We have recently generated a novel monoclonal antibody against a rheumatoid synovial T cell line that recognizes an antigen termed UM4D4 (CDw6O). This antigen is expressed on a minority of peripheral blood T cells, and represents the surface component of a distinct pathway of human T cell activation. The current studies were performed to examine the expression and function of UM4D4 on
