title: Danazol therapy in haemophilia.
abstract: Three patients with severe haemophilia A and one patient with moderately severe Christmas disease were given danazol and placebo in a double blind cross over trial to study the effects on haemostatic variables and bleeding tendency. In each case there was a shortening of the activated partial thromboplastin time (APTT) and euglobulin clot lysis time (ECLT) during danazol therapy but factor VIII and IX levels did not show any consistent change and there was no improvement in the bleeding tendency.
