title: Monoclonal antibodies to human T cell subsets: use for immunological monitoring and immunosuppression in renal transplantation.
abstract: Sequential monitoring of peripheral blood T cell populations was performed in normal control individuals and in 55 renal allograft recipients. In addition, 66 patients exhibiting prolonged renal allograft survival were each evaluated at least once with the same monoclonal antibodies. A normal or elevated OKT4:OKT8 ratio, especially in the presence of rising numbers of OKT4+ cells was predictive of possible future graft rejection. This observation, when followed by rising serum creatinine values coupled with biopsy evidence of glomerulopathy, was found in at least 15% of graft recipients. In a small number of patients, graft rejection episodes were successfully suppressed by administration of therapeutic doses of OKT3 antibody. However, production of anti-OKT3 antibodies was observed and may be expected to limit administration of this agent to a single short course in each patient.
