title: Shortening of bleeding time after intranasal administration of 1-deamino-8-D-arginine vasopressin to patients with chronic uremia.
abstract: 1-deamino-8-D-arginine vasopressin (DDAVP) was administered intranasally in a dose of 2 micrograms/kg BW to 17 uremic patients (16 maintained on chronic hemodialysis and 1 treated conservatively). The bleeding time was significantly shortened 120 minutes after DDAVP administration (from 18.1 +/- 7.5 minutes to 12.3 +/- 6.4 minutes p less than 0.001). Factor VIII related antigen (VIII: Ag) did not change. Factor VIII ristocetin cofactor activity (VIII: RCof) significantly increased (from 251.2 +/- 162.0 to 336.5 +/- 167.2 p less than 0.025). Platelet count decreased significantly after DDAVP (from 174.9 +/- 43.8 X 10(9)/l to 155.6 +/- 45.9 X 10(9)/l 30 minutes p less than 0.01 and 129.8 +/- 45.2 X 10(9)/l p less than 0.005 120 minutes after DDAVP). Antithrombin III concentration, and hematocrit did not change. Our data indicate that further clinical studies of intranasal DDAVP in uremic patients during episodes of bleeding are warranted.
