Abstract
We have examined platelet aggregation in patients with chronic uremia using ADP, thrombin and calcium ionophore A23187 as inducers. The study was performed on patients treated conservatively, by hemodialysis and peritoneal dialysis. Platelet aggregation was most significantly depressed in patients treated conservatively and by hemodialysis. Different mechanisms are responsible for platelet dysfunction.
