Effect of peritoneal dialysis, haemodialysis and kidney transplantation on blood platelet function. I. Platelet aggregation by ADP and epinephrine.

Quantitation of the thrombocytopathy of uraemics may be one useful way of evaluating forms of therapy. 24 patients treated by haemodialysis and peritoneal dialysis at two different times had platelet aggregation studies whose parameters were compared with those of 24 normal persons, 5 successful transplants or 13 untreated uraemics. Renal transplantation and peritoneal dialysis improved platelet function. The haemodialysis procedure itself impaired platelet function: this was not due to heparin.
