Platelet surface receptors for von Willebrand factor and for fibrinogen (glycoproteins GPIb and GPIIb/IIIa) were studied with monoclonal antibodies CD42 and CD41 and cytofluorometry in 31 healthy subjects, 10 hemodialysis patients with no A-V fistula obstruction (patent original fistula), 10 hemodialysis patients with frequent A-V fistula obstruction (more than twice), 12 patients with mild chronic renal failure (creatinine 1.75 +- 0.40 mg/100ml), 11 patients with advanced chronic renal failure (creatinine 5.62 +- 1.22 mg/100ml), and 10 patients with end-stage renal disease (ESRD) treated with peritoneal dialysis. There was a significant increase of platelet surface glycoproteins GPIb and GPIIb/IIIa in the population of hemodialysis patients with frequent A-V fistula obstruction. The expression of these platelet receptors might be related to the prothrombotic tendency of a group of patients with ESRD, who suffer more occlusive and thrombotic events of the A-V fistula. This group of patients may also have a higher frequency of systemic thrombotic and atherosclerotic complications.
