Abstract

Factor VIII (FVIII) response to desmopressin (deamino-8-D-arginine vasopressin, abbreviated DDAVP) was studied in patients with mild Hemophilia A and von Willebrand Disease (vWD) who attend our Hemophilia Clinic. Thirty eight children and 9 adults had their F VIII components assayed 60 minutes after intravenous (IV) administration of DDAVP, 0.35 microgram/kg. Among 27 hemophiliacs, F VIII coagulant activity (F VIII: C) increased from a mean of 16.8 to 59.2 u/dL; with an average 3.2-fold increase. In 20 vWD patients, the mean F VIII:C and von Willebrand Factor increased from a mean of 50.1 to 136%; and from 22.6 to 75.6%; with an average 3.0 and 5.7-fold increase, respectively. The overall F VIII:C response was good or excellent in 81.5% of the hemophiliacs, and in 89.5% of the vWD patients tested. No significant side effects were observed. This study has demonstrated that IV DDAVP can cause an increase of F VIII:C and vWF to hemostatic levels, and thus it may be useful for the control of bleeding episodes in most of the patients tested in our clinic.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
