Abstract
We have evaluated the duration of the effect of replacement therapy with two different doses of fibrinogen on the prolonged bleeding time of an afibrinogenaemic patient and the relationship between changes in bleeding time and plasma and platelet fibrinogen concentrations. The infusion of 40 mg/kg fibrinogen, as fresh frozen plasma (FFP), corrected the prolonged bleeding time of the patient from longer that 30 min to 8 min. The bleeding time was still normal 9 d after infusion, at a time when the plasma and platelet fibrinogen levels were low (0.13 g/l and 27 μg/109 platelets; normal ranges 1.6-4.0 and 60-190). Two months later, the infusion of a smaller dose of fibrinogen (4 mg/kg) also corrected the bleeding time, which remained normal until the second day after infusion, despite the fact that plasma and platelet fibrinogen were very low (0.02 g/l and 3.4 μg/109 platelets). The bleeding time returned to the prolonged baseline values only by day 6 post-infusion, when plasma and platelet fibrinogen levels were 4 x 10-4 g/l and 1.4 μg/109 platelets. Therefore, sustained correction of the prolonged bleeding time may be obtained in afibrinogenaemic patients with a single infusion of fibrinogen at lower doses than usually recommended.
