• B-lymphocyte functions were studied in peripheral blood mononuclear cells of end-stage renal disease patients undergoing intermittent hemodialysis for longer than two years. T-cell—dependent B lymphocyte proliferation after pokeweed mitogen stimulation was low in half of the hemodialyzed patients. T cell—independent B cell response to Staphylococcus aureus, Cowan I, was also significantly reduced. Spontaneous production of immunoglobulin in cultures of peripheral blood mononuclear cells of uremic patients was comparable with that of healthy controls, but pokeweed mitogen—stimulated antibody secretion was significantly reduced with cells from patients undergoing hemodialysis. Helper T-cell functions in B-cell activation were also qualitatively deficient in uremic patients. It is concluded that B-cell activation and immunoregulation is defective in patients undergoing long-term hemodialysis.
