Abstract

Background

Hemophilia A is the most common serious bleeding disorder, and the hallmark of this disease is joint bleeding episodes. These result in hemophilic synovitis, an inflammatory and proliferative condition of the joint, which progresses into a chronic degenerative arthritis, hemophilic arthropathy.

Methods

In this paper, we describe the effect of recombinant factor VIIa (rFVIIa), and an analogue NN1731 as well as rFVIII on needle-induced bleeding in hemophilia A mice.

Conclusions

Here we show a reducing effect of rFVIIa and NN1731 on bleeding induced in hemophilic mice, and we show that preventive treatment with rFVIII normalizes bleeding.
