title: Chronic T-lymphocyte activation in chronic renal failure: a study of hemodialysis, CAPD and pre-dialysis patients.
abstract: In this study we measured indices of T-lymphocyte activation in normal volunteers, chronic hemodialysis patients, CAPD patients and chronic renal failure patients not yet on dialysis. Serum IL-2 levels were elevated in patients compared to controls. Soluble IL-2 receptors were elevated in all three patient groups and were highest in CAPD patients. Clearance of IL-2 and soluble interleukin receptors was negligible in dialysis and renal failure patients. Hemodialysis patients had a significantly lower percentage of CD3-positive cells than all other groups. Hemodialysis with a variety of membrane/bath combinations did not significantly affect any of the parameters measured. This study provides some support for the hypothesis that chronic T-cell activation is present in renal failure.
